    Studies on ancient coral communities living in marginal conditions, including low light, high turbidity, extreme temperatures, or high nutrients, are important to understand the current structure of reefs and how they could potentially respond to global changes. The main goal of this study was to document the rich and well-preserved fossil coral fauna preserved in Miocene exposures of the Kutai Basin in East Kalimantan, Indonesia. Our collections include almost forty thousand specimens collected from 47 outcrops. Seventy-nine genera and 234 species have been identified. Three different coral assemblages were found corresponding to small patch reefs that developed under the influence of high siliciclastic inputs from the Mahakam Delta. Coral assemblages vary in richness, structure, and composition. Platy coral assemblages were common until the Serravallian (Middle Miocene), while branching coral assemblages became dominant in the Tortonian (Late Miocene). By the late Tortonian massive coral assemblages dominated, similar to modern-style coral framework. Our results suggest that challenging habitats, such as the Miocene turbid habitats of East Kalimantan, might have played an important role during the early diversification of the Coral Triangle by hosting a pool of resilient species more likely to survive the environmental changes that have affected this region since the Cenozoic. Further research that integrates fossil and recent turbid habitats may provide a glimpse into the dynamics and future of coral reefs as "typical" clear-water reefs continue to decline in most regions.

    Faecal samples from 163 captive and semi-captive individuals, 61 samples from wild individuals and 38 samples from captive groups of Bornean orangutans (Pongo pygmaeus) in Kalimantan, Indonesia, were collected during one rainy season (November 2005-May 2006) and screened for intestinal parasites using sodium acetate-acetic acid-formalin-concentration (SAFC), sedimentation, flotation, McMaster- and Baermann techniques. We aimed to identify factors influencing infection risk for specific intestinal parasites in wild orangutans and individuals living in captivity. Various genera of Protozoa (including Entamoeba, Endolimax, Iodamoeba, Balantidium, Giardia and Blastocystis), nematodes (such as Strongyloides, Trichuris, Ascaris, Enterobius, Trichostrongylus and hookworms) and one trematode (a dicrocoeliid) were identified. For the first time, the cestode Hymenolepis was detected in orangutans. Highest prevalences were found for Strongyloides (individuals 37%; groups 58%), hookworms (41%; 58%), Balantidium (40%; 61%), Entamoeba coli (29%; 53%) and a trichostrongylid (13%; 32%). In re-introduction centres, infants were at higher risk of infection with Strongyloides than adults. Infection risk for hookworms was significantly higher in wild males compared with females. In groups, the centres themselves had a significant influence on the infection risk for Balantidium. Ranging patterns of wild orangutans, overcrowding in captivity and a shift of age composition in favour of immatures seemed to be the most likely factors leading to these results. PMID:19765342

    Large-scale fires occur frequently across Indonesia, particularly in the southern region of Kalimantan and eastern Sumatra. They have considerable impacts on carbon emissions, haze production, biodiversity, health, and economic activities. In this study, we demonstrate that severe fire and haze events in Indonesia can generally be predicted months in advance using predictions of seasonal rainfall from the ECMWF System 4 coupled ocean-atmosphere model. Based on analyses of up-to-date and long series observations on burnt area and rainfall, and tree cover, we demonstrate that fire activity is negatively correlated with rainfall, and is positively associated with deforestation in Indonesia. There is a contrast between the southern region of Kalimantan (high fire activity, high tree cover loss and strong non-linear correlation between observed rainfall and fire) and the central region of Kalimantan (low fire activity, low tree cover loss and weak non-linear correlation between observed rainfall and fire). The ECMWF seasonal forecast provides skilled forecasts of burnt area with several months lead time explaining at least 70% of the variance between rainfall and with burnt area. Results are strongly influenced by El Niño years which show a consistent positive bias. Overall, our findings point to a high potential for using a more physical-based method for predicting fires with several months lead time in the tropics, rather than one based on indexes only. We argue that seasonal precipitation forecasts should be central to Indonesia's evolving fire management policy.

    These many and intense land clearing fires in the Kalimantan region of the island of Borneo, Indonesia (3.5S, 113.5E) are indicative of the many deforestation activities on a worldwide scale. In order to feed and house ever increasing populations, more cleared land is required for agriculture to feed ever increasing populations. More pasture lands are needed for livestock. And, more cleared lands are needed for housing.

    The Kenyah Dayak in East Kalimantan (Indonesia), who migrated from their mountainous homeland to a riverine village in the 1940s, have subsisted on slash-and-burn rice cultivation. To cope with rapidly increasing population, the villagers have not changed their farming practice to increase land productivity but instead have exploited fields in remote riverbanks, using motorized canoes.

    Smoke and haze blanketed western Indonesia during August and September 2002, signaling the arrival of another El Niño event in Southeast Asia. Although not as severe as the 1997-1998 El Niño event, the 2002 El Niño produced drought conditions in western Indonesia that favored extensive biomass burning in lowland areas of Borneo, Sumatra, and Sulawesi, three of the largest islands that form part of the vast Indonesian archipelago. Data derived from the Moderate Resolution Imaging Spectrometer (MODIS) on board the NASA Terra satellite showed that most of the burning during 2002 occurred in central and western Kalimantan (Indonesian Borneo), where forests are being cleared to make way for industrial oil palm and pulp plantations.Comparison of fire data from several different satellite sensors also reveals that fires detected in Kalimantan during 1997 appeared more numerous (Figure 1) and burned over a longer period (Figure 2) than fires that burned in late 2002 (see discussion below). This result is consistent with recent El Niño observations that characterize the current event as moderate relative to the 1997-1998 event (see http://www.cpc.ncep.noaa.gov/ products/analysis_monitoring/enso_advisory/).

    Interpretations of Oligocene shelfal limestones from Central Kalimantan, Indonesia, suggest caution in predicting sea-level lowstands from seismic reflector patterns or published sea-level curves. Three major depositional sequences, each 200-400 m thick, were delineated in outcrops and seismic lines: late Eocene to early Oligocene (34-38 Ma), middle Oligocene (29.7-32 Ma), and early late Oligocene (28-29.7 Ma). The lowest sequence is mainly shale with tin sandstones and limestones (large-foram wackestone). The middle and upper sequences are carbonate with transgressive systems tracts (TSTs) overlain by highstand systems tracts (HSTs). TSTs contain large-foram wackestone-packstones and coral wackestone-packstones. HSTs are characterized by (1) shale and carbonate debris flows deposited on the lower slope, (2) argillaceous large-foram wackestones on the upper slope, (3) discontinuous coral wackestones and boundstones on the shelf margin, (4) bioclastic packstones and grainstones on backreef flats and shelf-margin shoals, and (5) branching-coral and foraminiferal wackestones in the lagoon. Bases of sequences are characterized by transgression and onlap. Deepending and/or drowning of the carbonate shelf occurred at the top of the middle and upper sequences. Basinal strata that apparently onlap the middle and upper carbonate shelf margins might be misinterpreted as lowstand deposits, although regional studies indicate they are prodelta sediments baselapping against the shelf. Shallowing the subaerial exposure of the carbonates might be expected during the large mid-Oligocene (29.5-30 Ma) sea-level drop of Haq et al. (1987), instead of the observed deepening and local drowning.

  9. Oil palm plantation effects on water quality in Kalimantan, Indonesia

    Global demand for palm oil has stimulated a 7-fold increase in oil palm (Elaeis guineensis) plantation area in Indonesia since 1990. Expansion will continue as Indonesia plans to double current production by 2020. Oil palm fertilizers, effluent from oil palm mills, and erosion from land clearing and roads threaten river water quality near plantations. These rivers provide essential ecosystem services including water for drinking, cooking, and washing. Robust empirical measurements of plantation expansion impacts on water resources are necessary to discern the effects of agribusiness on local livelihoods and ecosystems. In Ketapang District, West Kalimantan, Indonesian Borneo, we evaluated the effects of land cover change on water quality by assessing water chemistry in streams draining four end-member watersheds ( ~600-1900 ha watershed-1): Logged forest, mixed agro-forest dominated by rubber and upland rice fallows, young oil palm forest (0-5 years), and old oil palm forest (10-15 years). To assess land cover change, we used CLASLite software to derive fractional cover from a time series (1989-2008) of Landsat data. Nearest neighbor classification and post-classification change detection yielded classes including primary forest, logged forest, secondary forest regrowth, smallholder agriculture, and oil palm. Stream water quality (temperature, dissolved oxygen, turbidity, optical chlorphyll, and pH) and quantity (discharge) were quantified with the YSI 6600-V2 sonde. The sonde was deployed in each stream for month-long intervals 2-3 times from 2009-2010. Such extended deployment captures episodic events such as intense storms and allows examination of interdiel dynamics by sampling continuously and at high frequency, every 10 minutes. We find that across the Ketapang District study region (~12,000 km2), oil palm has cleared mostly forests (49%) and agroforests (39%). What are the impacts of such land cover changes on water quality? Compared to forests and

    Introduction Indonesia is an archipelago of more than 17,000 islands that stretches astride the equator for about 5,200 km in southeast Asia (figure 1) and includes major Cenozoic volcano-plutonic arcs, active volcanoes, and various related onshore and offshore basins. These magmatic arcs have extensive Cu and Au mineralization that has generated much exploration and mining in the last 50 years. Although Au and Ag have been mined in Indonesia for over 1000 years (van Leeuwen, 1994), it was not until the middle of the nineteenth century that the Dutch explored and developed major Sn and minor Au, Ag, Ni, bauxite, and coal resources. The metallogeny of Indonesia includes Au-rich porphyry Cu, porphyry Mo, skarn Cu-Au, sedimentary-rock hosted Au, epithermal Au, laterite Ni, and diamond deposits. For example, the Grasberg deposit in Papua has the world's largest gold reserves and the third-largest copper reserves (Sillitoe, 1994). Coal mining in Indonesia also has had a long history beginning with the initial production in 1849 in the Mahakam coal field near Pengaron, East Kalimantan; in 1891 in the Ombilin area, Sumatra, (van Leeuwen, 1994); and in South Sumatra in 1919 at the Bukit Asam mine (Soehandojo, 1989). Total production from deposits in Sumatra and Kalimantan, from the 19thth century to World War II, amounted to 40 million metric tons (Mt). After World War II, production declined due to various factors including politics and a boom in the world-wide oil economy. Active exploration and increased mining began again in the 1980's mainly through a change in Indonesian government policy of collaboration with foreign companies and the global oil crises (Prijono, 1989). This recent coal revival (van Leeuwen, 1994) has lead Indonesia to become the largest exporter of thermal (steam) coal and the second largest combined thermal and metallurgical (coking) coal exporter in the world market (Fairhead and others, 2006). The exported coal is desirable as it is low sulfur

    The author describes the role of population pressure in the current transition from tree crops to wet rice cultivation (sawah) in Northwestern Kalimantan, Indonesia. He contends that this change is occurring "because the senescent trees no longer produce enough commodities to exchange for rice to feed an enlarged population." The historical background is described, policies of the Indonesian government are discussed, and data are presented on the rate of population growth

    During the PACE-5 campaign over Australia and Indonesia in October 1997, we used an aircraft to measure carbon monoxide (CO) and hydrogen (H2). Latitudinal distributions of CO and H2 clearly showed a large increase from northern Australia to Kalimantan in Indonesia. Elevated CO levels over northern Australia were observed only in the smoke plumes of savanna fires. A thick smoke haze from forest fires over Kalimantan contained very high CO mixing ratios of 3 to 9 ppm. These enhanced CO mixing ratios correlated well with increased concentrations of H2, nitrogen oxides (NOx), and aerosols. Emission ratios from biomass burning in Kalimantan ranged 0.06 0.1 for H2/CO (ppb/ppb), 0.0002 to 0.0005 for NOx/CO (ppb/ppb), and 0.43 to 1.0 for number of aerosols/CO (cm-3/ppb). These values were much lower than emission ratios in northern Australia. This difference suggests that the biomass burning in Indonesia was intense and that, due to a strong El Niño event, an unique composition of trace gases was formed in the smoke haze.

    In order to improve the knowledge and skills of midwives at health facilities and those based in villages in South Kalimantan, Indonesia, three in-service training programmes were carried out during 1995-98. A scheme used for both facility and village midwives included training at training centres, peer review and continuing education. One restricted to village midwives involved an internship programme in district hospitals. The incremental cost-effectiveness of these programmes was assessed from the standpoint of the health care provider. It was estimated that the first scheme could be expanded to increase the number of competent midwives based in facilities and villages in South Kalimantan by 1% at incremental costs of US$ 764.6 and US$ 1175.7 respectively, and that replication beyond South Kalimantan could increase the number of competent midwives based in facilities and villages by 1% at incremental costs of US$ 1225.5 and US$ 1786.4 per midwife respectively. It was also estimated that the number of competent village midwives could be increased by 1% at an incremental cost of US$ 898.1 per intern if replicated elsewhere, and at a cost of US$ 146.2 per intern for expanding the scheme in South Kalimantan. It was not clear whether the training programmes were more or less cost-effective than other safe motherhood interventions because the nature of the outcome measures hindered comparison.

    A survey was carried out among inhabitants of eight villages in West Kalimantan Province (Borneo), whereby blood smears were examined for malaria, stools examined for intestinal parasites and sera tested by the indirect hemagglutination test for antibodies to Entamoeba histolytica and toxoplasma gondii. The prevalence of malaria among 3017 people examined was 5.6% (Plasmodium vivax 2.8%, Plasmodium falciparum 2.8%). Brugia malayi microfilariae were found in 3.6% and Wuchereria bancrofti in 0.3%. Ninety-seven percent of 2101 stool specimens examined contained evidence of intestinal parasites. Trichuris trichiura (90%) was most common followed by Ascaris lumbricoides (76%), hookworm, (60%), Etamoeba coli (23%), Entamoeba histolytica (6%), Endolimax nana (6%), Iodamoeba butschlii (4%), Giardia lamblia (3%), Chilomastix mesnili (1%) and Strongyloides stercoralis (1%). Other parasites found were Entamoeba hartmanni, Trichomonas hominis, Balantidium coli, Enterobius vermicularis, Hymenolepis nana, Echinostoma sp. and Physalopterid, Dicrocoeliid, and Heterophyid type-eggs. The amoeba prevalence rate was 30%. Indirect hemagglutination antibody titers equal to or greater than 1:128 for Entamoeba histolytica and 1:256 for Toxoplasma gondii were detected in 7% and 3%, respectively, of 1511 sera tested.

    The identity of the common lowland freshwater crab in western Sarawak, Borneo, East Malaysia, Parathelphusa oxygona Nobili, 1901 (family Gecarcinucidae), is clarified. The species is redescribed and figured, and its taxonomy discussed. Specimens from western Kalimantan, Borneo, Indonesia, which have been referred to P. oxygona are here referred to a new species, Parathelphusa nobilii. The new species can be differentiated from congeners by its relatively more swollen branchial regions of the carapace, wider and lower external orbital tooth, relatively more slender male abdomen and a straight male first gonopod.

    The past decade marked record high air pollution episodes in Indonesia. In this study, we specifically focus on vegetation fires in Palangkaraya located near a Mega Rice Project area in Indonesia. We analyzed various gaseous air pollution data such as particulate matter (PM10), SO2, CO, O3, and NO2 study region. We also conducted elemental analysis at two different sites. Results from 2001 to 2010 suggested the longest hazardous air pollution episode during 2002 lasting about 80 days from mid-August to late-October. Maximum peak concentrations of PM10, SO2, CO, and O3 were also observed during 2002 and their values reached 1905, 85.8, 38.3, and 1003×10(-6) gm(-3) respectively. Elemental analysis showed significant increase in concentrations during 2011 and 2010. Satellite retrieved fires and weather data could explain most of the temporal variations. Our results highlight peat fires as a major contributor of photochemical smog and air pollution in the region.

    Indonesia has become the world's largest exporter of thermal coal and is a major supplier to the Asian coal market, particularly as the People's Republic of China is now (2007) and perhaps may remain a net importer of coal. Indonesia has had a long history of coal production, mainly in Sumatra and Kalimantan, but only in the last two decades have government and commercial forces resulted in a remarkable coal boom. A recent assessment of Indonesian coal-bed methane (CBM) potential has motivated active CBM exploration. Most of the coal is Paleogene and Neogene, low to moderate rank and has low ash yield and sulfur (generally < 10 and < 1??wt.%, respectively). Active tectonic and igneous activity has resulted in significant rank increase in some coal basins. Eight coal samples are described that represent the major export and/or resource potential of Sumatra, Kalimantan, Sulawesi, and Papua. Detailed geochemistry, including proximate and ultimate analysis, sulfur forms, and major, minor, and trace element determinations are presented. Organic petrology and vitrinite reflectance data reflect various precursor flora assemblages and rank variations, including sample composites from active igneous and tectonic areas. A comparison of Hazardous Air Pollutants (HAPs) elements abundance with world and US averages show that the Indonesian coals have low combustion pollution potential.

    Around the world, governments are establishing national forest monitoring systems (NFMS) that use a combination of remote sensing and ground-based forest carbon inventory approaches to estimate anthropogenic forest-related greenhouse gas emissions and removals. The NFMS forms the link between historical assessments and current/future assessments of forests, enabling consistency in the data and information to support the implementation of REDD+ activities. The creation of a reliable, transparent, and comprehensive NFMS is currently limited by a dearth of relevant data that are accurate, low-cost, and spatially resolved at subnational scales. With funding from a 3-year NASA Carbon Monitoring System project beginning in September 2013, we are developing, evaluating, and validating several critical components of an NFMS in Kalimantan, Indonesia, focusing on the use of LiDAR and radar imagery for improved carbon stock and forest degradation information. Here, we present results from an initial analysis of a spatially extensive set of LiDAR data collected across the Indonesian provinces on the island of Borneo together with RADAR and optical data. Our objectives are to evaluate sensor and platform tradeoffs systematically against in situ investments, as well as provide detailed tracking and characterization of uncertainty in a cost-benefit framework. Kalimantan is an ideal area to evaluate the use of remote sensing methods because measuring forest carbon stocks and their human caused changes with a high degree of certainty on the ground can be difficult. While our work focuses at the subnational scale for Kalimantan, we are targeting these methods for applicability across broader geographies and for implementation at various scales.

    Our society faces the pressing challenge of increasing agricultural production while minimizing negative consequences on ecosystems and the global climate. Indonesia, which has pledged to reduce greenhouse gas (GHG) emissions from deforestation while doubling production of several major agricultural commodities, exemplifies this challenge. Here we focus on palm oil, the world's most abundant vegetable oil and a commodity that has contributed significantly to Indonesia's economy. Most oil palm expansion in the country has occurred at the expense of forests, resulting in significant GHG emissions. We examine the extent to which land management policies can resolve the apparently conflicting goals of oil palm expansion and GHG mitigation in Kalimantan, a major oil palm growing region of Indonesia. Using a logistic regression model to predict the locations of new oil palm between 2010 and 2020 we evaluate the impacts of six alternative policy scenarios on future emissions. We estimate net emissions of 128.4-211.4 MtCO2 yr(-1) under business as usual expansion of oil palm plantations. The impact of diverting new plantations to low carbon stock land depends on the design of the policy. We estimate that emissions can be reduced by 9-10% by extending the current moratorium on new concessions in primary forests and peat lands, 35% by limiting expansion on all peat and forestlands, 46% by limiting expansion to areas with moderate carbon stocks, and 55-60% by limiting expansion to areas with low carbon stocks. Our results suggest that these policies would reduce oil palm profits only moderately but would vary greatly in terms of cost-effectiveness of emissions reductions. We conclude that a carefully designed and implemented oil palm expansion plan can contribute significantly towards Indonesia's national emissions mitigation goal, while allowing oil palm area to double.

    We evaluated three spatially explicit land use and cover change (LUCC) models to project deforestation from 2005-2020 in the carbon-rich peat swamp forests (PSF) of Central Kalimantan, Indonesia. Such models are increasingly used to evaluate the impact of deforestation on carbon fluxes between the biosphere and the atmosphere. We considered both business-as-usual (BAU) and a forest protection scenario to evaluate each model's accuracy, sensitivity, and total projected deforestation and landscape-level fragmentation patterns. The three models, Dinamica EGO (DE), GEOMOD and the Land Change Modeler (LCM), projected similar total deforestation amounts by 2020 with a mean of 1.01 million ha (Mha) and standard deviation of 0.17 Mha. The inclusion of a 0.54 Mha strict protected area in the LCM simulations reduced projected loss to 0.77 Mha over 15 years. Calibrated parameterizations of the models using nearly identical input drivers produced very different landscape properties, as measured by the number of forest patches, mean patch area, contagion, and Euclidean nearest neighbor determined using Fragstats software. The average BAU outputs of the models suggests that Central Kalimantan may lose slightly less than half (45.1%) of its 2005 PSF by 2020 if measures are not taken to reduce deforestation there. The relatively small reduction of 0.24 Mha in deforestation found in the 0.54 Mha protection scenario suggests that these models can identify potential leakage effects in which deforestation is forced to occur elsewhere in response to a policy intervention.

We considered both business-as-usual (BAU) and a forest protection scenario to evaluate each model's accuracy, sensitivity, and total projected deforestation and landscape-level fragmentation patterns. The three models, Dinamica EGO (DE), GEOMOD and the Land Change Modeler (LCM), projected similar total deforestation amounts by 2020 with a mean of 1.01 million ha (Mha) and standard deviation of 0.17 Mha. The inclusion of a 0.54 Mha strict protected area in the LCM simulations reduced projected loss to 0.77 Mha over 15 years. Calibrated parameterizations of the models using nearly identical input drivers produced very different landscape properties, as measured by the number of forest patches, mean patch area, contagion, and Euclidean nearest neighbor determined using Fragstats software. The average BAU outputs of the models suggests that Central Kalimantan may lose slightly less than half (45.1%) of its 2005 PSF by 2020 if measures are not taken to reduce deforestation there. The relatively small reduction of 0.24 Mha in deforestation found in the 0.54 Mha protection scenario suggests that these models can identify potential leakage effects in which deforestation is forced to occur elsewhere in response to a policy intervention.

    Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have been requested to establish robust and transparent national forest monitoring systems (NFMS) that use a combination of remote sensing and ground-based forest carbon inventory approaches to estimate anthropogenic forest-related greenhouse gas emissions and removals, reducing uncertainties as far as possible. A country's NFMS should also be used for data collection to inform the assessment of national or subnational forest reference emission levels and/or forest reference levels (RELs/RLs). In this way, the NFMS forms the link between historical assessments and current/future assessments, enabling consistency in the data and information to support the implementation of REDD+ activities in countries. The creation of a reliable, transparent, and comprehensive NFMS is currently limited by a dearth of relevant data that are accurate, low-cost, and spatially resolved at subnational scales. We are developing, evaluating, and validating several critical components of an NFMS in Kalimantan, Indonesia, focusing on the use of LiDAR and radar imagery for improved carbon stock and forest degradation information. Our goal is to evaluate sensor and platform tradeoffs systematically against in situ investments, as well as provide detailed tracking and characterization of uncertainty in a cost-benefit framework. Kalimantan is an ideal area to evaluate the use of remote sensing methods because measuring forest carbon stocks and their human caused changes with a high degree of certainty in areas of dense tropical forests has proven to be difficult. While the proposed NFMS components are being developed at the subnational scale for Kalimantan, we are targeting these methods for applicability across broader geographies and for implementation at various scales. Our intention is for this research to advance the state of the art of Measuring, Reporting, and Verification (MRV) system methodologies in ways

    Quantification of the spatial needs of individuals and populations is vitally important for management and conservation. Geographic information systems (GIS) have recently become important analytical tools in wildlife biology, improving our ability to understand animal movement patterns, especially when very large data sets are collected. This study aims at combining the field of GIS with primatology to model and analyse space-use patterns of wild orang-utans. Home ranges of female orang-utans in the Tuanan Mawas forest reserve in Central Kalimantan, Indonesia were modelled with kernel density estimation methods. Kernel results were compared with minimum convex polygon estimates, and were found to perform better, because they were less sensitive to sample size and produced more reliable estimates. Furthermore, daily travel paths were calculated from 970 complete follow days. Annual ranges for the resident females were approximately 200 ha and remained stable over several years; total home range size was estimated to be 275 ha. On average, each female shared a third of her home range with each neighbouring female. Orang-utan females in Tuanan built their night nest on average 414 m away from the morning nest, whereas average daily travel path length was 777 m. A significant effect of fruit availability on day path length was found. Sexually active females covered longer distances per day and may also temporarily expand their ranges.

    Forested tropical peatlands in Southeast Asia are being rapidly converted to agriculture or degraded into non-forest vegetation. Although large areas have been abandoned, there is little evidence for subsequent forest recovery. As part of a study of forest degradation and recovery, we used seed removal experiments and rodent surveys to investigate the potential role of post-dispersal seed predation in limiting the regeneration of woody plants. Two 14-day seed removal trials were done in deforested and forested peatland habitat in Central Kalimantan, Indonesia. Seeds of Nephelium lappaceum, Syzygium muelleri, Artocarpus heterophyllus (all animal-dispersed) and Combretocarpus rotundatus (wind-dispersed) were tested. Significantly more seeds (82.8%) were removed in forest than non-forest (38.1%) and Combretocarpus had the lowest removal in both habitats. Most handled seeds were eaten in situ and little caching was observed. Six species of rodents were captured in forest and five in non-forest. The most trapped taxa were three Maxomys spp. in forest (85.5% of individuals) and Rattus tiomanicus in non-forest (74.8%). Camera traps confirmed that rodents were responsible for seed removal. Seed predation in deforested areas, which have a much lower seed rain than forest, may contribute to the low density and diversity of regenerating forest. PMID:26369444

    There is increasing experience with the valuation of ecosystem services. However, to date, less attention has been devoted to who is actually benefiting from ecosystem services. This nevertheless is a key issue, in particular, if ecosystem services analysis and valuation is used to support environmental management. This study assesses and analyzes how the monetary benefits of seven ecosystem services are generated in Central Kalimantan Province, Indonesia, are distributed to different types of beneficiaries. We analyze the following ecosystem services: (1) timber production; (2) rattan collection; (3) jelutong resin collection; (4) rubber production (based on permanent agroforestry systems); (5) oil palm production on three management scales (company, plasma farmer, and independent smallholder); (6) paddy production; and (7) carbon sequestration. Our study shows that the benefits generated from these services differ markedly between the stakeholders, which we grouped into private, public, and household entities. The distribution of these benefits is strongly influenced by government policies and in particular benefit sharing mechanisms. Hence, land-use change and policies influencing land-use change can be expected to have different impacts on different stakeholders. Our study also shows that the benefits generated by oil palm conversion, a main driver for land-use change in the province, are almost exclusively accrued by companies and at this point in time are shared unequally with local stakeholders.

    Our society faces the pressing challenge of increasing agricultural production while minimizing negative consequences on ecosystems and the global climate. Indonesia, which has pledged to reduce greenhouse gas (GHG) emissions from deforestation while doubling production of several major agricultural commodities, exemplifies this challenge. Here we focus on palm oil, the world’s most abundant vegetable oil and a commodity that has contributed significantly to Indonesia’s economy. Most oil palm expansion in the country has occurred at the expense of forests, resulting in significant GHG emissions. We examine the extent to which land management policies can resolve the apparently conflicting goals of oil palm expansion and GHG mitigation in Kalimantan, a major oil palm growing region of Indonesia. Using a logistic regression model to predict the locations of new oil palm between 2010 and 2020 we evaluate the impacts of six alternative policy scenarios on future emissions. We estimate net emissions of 128.4–211.4 MtCO2 yr-1 under business as usual expansion of oil palm plantations. The impact of diverting new plantations to low carbon stock land depends on the design of the policy. We estimate that emissions can be reduced by 9-10% by extending the current moratorium on new concessions in primary forests and peat lands, 35% by limiting expansion on all peat and forestlands, 46% by limiting expansion to areas with moderate carbon stocks, and 55–60% by limiting expansion to areas with low carbon stocks. Our results suggest that these policies would reduce oil palm profits only moderately but would vary greatly in terms of cost-effectiveness of emissions reductions. We conclude that a carefully designed and implemented oil palm expansion plan can contribute significantly towards Indonesia’s national emissions mitigation goal, while allowing oil palm area to double.

    The main purpose of this paper is looking at the relationship between the factors of technical, financial and legal with enterprise value in mergers and acquisitions of coal companies in Kalimantan, Indonesia over the last 10 years. Data obtained from secondary data sources in the company works and from published data on the internet. The data thus obtained are as many as 46 secondary data with parameters resources, reserves, stripping ratio, calorific value, distance from pit to port, and distance from ports to vessels, production per annum, the cost from pit to port, from port to vessel costs, royalties, coal price and permit status. The data was analysis using structural equation modeling (SEM) to determine the factors that most significant influence enterprise value of coal company in Kalimantan. The result shows that a technical matter is the factor that most affects the value of enterprise in coal merger and acquisition company. Financial aspect is the second factor that affects the enterprise value.

    Monitoring loss of humid tropical forests via remotely sensed imagery is critical for a number of environmental monitoring objectives, including carbon accounting, biodiversity, and climate modeling science applications. Landsat imagery, provided free of charge by the U.S. Geological Survey Center for Earth Resources Observation and Science (USGS/EROS), enables consistent and timely forest cover loss updates from regional to biome scales. The Indonesian islands of Sumatra and Kalimantan are a center of significant forest cover change within the humid tropics with implications for carbon dynamics, biodiversity maintenance and local livelihoods. Sumatra and Kalimantan feature poor observational coverage compared to other centers of humid tropical forest change, such as Mato Grosso, Brazil, due to the lack of ongoing acquisitions from nearby ground stations and the persistence of cloud cover obscuring the land surface. At the same time, forest change in Indonesia is transient and does not always result in deforestation, as cleared forests are rapidly replaced by timber plantations and oil palm estates. Epochal composites, where single best observations are selected over a given time interval and used to quantify change, are one option for monitoring forest change in cloudy regions. However, the frequency of forest cover change in Indonesia confounds the ability of image composite pairs to quantify all change. Transient change occurring between composite periods is often missed and the length of time required for creating a cloud-free composite often obscures change occurring within the composite period itself. In this paper, we analyzed all Landsat 7 imagery with <50% cloud cover and data and products from the Moderate Resolution Imaging Spectroradiometer (MODIS) to quantify forest cover loss for Sumatra and Kalimantan from 2000 to 2005. We demonstrated that time-series approaches examining all good land observations are more accurate in mapping forest cover change in

    Adoption of reduced-impact logging (RIL) methods could reduce CO2 emissions by 30-50% across at least 20% of remaining tropical forests. We developed two cost effective and robust indices for comparing the climate benefits (reduced CO2 emissions) due to RIL. The indices correct for variability in the volume of commercial timber among concessions. We determined that a correction for variability in terrain slope was not needed. We found that concessions certified by the Forest Stewardship Council (FSC, N = 3), when compared with noncertified concessions (N = 6), did not have lower overall CO2 emissions from logging activity (felling, skidding, and hauling). On the other hand, FSC certified concessions did have lower emissions from one type of logging impact (skidding), and we found evidence of a range of improved practices using other field metrics. One explanation of these results may be that FSC criteria and indicators, and associated RIL practices, were not designed to achieve overall emissions reductions. Also, commonly used field metrics are not reliable proxies for overall logging emissions performance. Furthermore, the simple distinction between certified and noncertified concessions does not fully represent the complex history of investments in improved logging practices. To clarify the relationship between RIL and emissions reductions, we propose the more explicit term 'RIL-C' to refer to the subset of RIL practices that can be defined by quantified thresholds and that result in measurable emissions reductions. If tropical forest certification is to be linked with CO2 emissions reductions, certification standards need to explicitly require RIL-C practices.

    Primates spend at least half their lives sleeping; hence, sleeping site selection can have important effects on behavior and fitness. As proboscis monkeys (Nasalis larvatus) often sleep along rivers and form bands (aggregations of one male groups) at their sleeping sites, understanding sleeping site selection may shed light on two unusual aspects of this species' socioecology: their close association with rivers and their multilevel social organization. We studied sleeping site selection by proboscis monkeys for twelve months at Sungai Tolak, West Kalimantan, Indonesia to test two main hypotheses regarding the drivers of sleeping site selection: reduction of molestation by mosquitoes and anti-predator behavior. We identified to genus and collected data on the physical structure (diameter at breast height, relative height, branch structure, and leaf coverage) of sleeping trees and available trees in three forest types. We used resource selection function models to test specific predictions derived from our two hypotheses. The monkeys preferred to sleep in large trees with few canopy connections located along rivers. The selection of large emergent trees was consistent with both of our main hypotheses: decreased molestation by mosquitoes and reduced potential entry routes for terrestrial predators. Although we are only beginning to understand how sleeping sites might influence behavior, grouping, and potential survival of this species, our study has shown that proboscis monkeys (at Sungai Tolak) have a very strong preference for large trees located near the river. As these trees are often the first to be logged by local villagers, this may exacerbate the problems of forest loss for these endangered monkeys.

    The Indonesian islands of Sumatera and Kalimantan (the Indonesian part of the island of Borneo) are a center of significant and rapid forest cover loss in the humid tropics with implications for carbon dynamics, biodiversity conservation, and local livelihoods. The aim of our research was to analyze and interpret annual trends of forest cover loss for different sub-regions of the study area. We mapped forest cover loss for 2000-2008 using multi-resolution remote sensing data from the Landsat enhanced thematic mapper plus (ETM +) and moderate resolution imaging spectroradiometer (MODIS) sensors and analyzed annual trends per island, province, and official land allocation zone. The total forest cover loss for Sumatera and Kalimantan 2000-2008 was 5.39 Mha, which represents 5.3% of the land area and 9.2% of the year 2000 forest cover of these two islands. At least 6.5% of all mapped forest cover loss occurred in land allocation zones prohibiting clearing. An additional 13.6% of forest cover loss occurred where clearing is legally restricted. The overall trend of forest cover loss increased until 2006 and decreased thereafter. The trends for Sumatera and Kalimantan were distinctly different, driven primarily by the trends of Riau and Central Kalimantan provinces, respectively. This analysis shows that annual mapping of forest cover change yields a clearer picture than a one-time overall national estimate. Monitoring forest dynamics is important for national policy makers, especially given the commitment of Indonesia to reducing greenhouse gas emissions as part of the reducing emissions from deforestation and forest degradation in developing countries initiative (REDD +). The improved spatio-temporal detail of forest change monitoring products will make it possible to target policies and projects in meeting this commitment. Accurate, annual forest cover loss maps will be integral to many REDD + objectives, including policy formulation, definition of baselines, detection

    Hepatitis B virus (HBV) from gibbons was characterized, and the possibility of horizontal transmission between gibbons and humans was examined in a gibbon rehabilitation center in Central Kalimantan, Indonesia. Ten gibbons that were positive for the hepatitis B surface antigen (HBsAg) on arrival and 13 caretakers for those gibbons were included in this study. The duration of stay at the rehabilitation center ranged from 1 to 10 years. Serological and molecular analyses were performed. Six gibbons were positive for HBsAg, whereas HBV DNA was detected in all ten of the gibbons sampled. On the other hand, HBsAg was detected in only 1 of the 13 caretakers. HBV samples from seven gibbons and from the one infected human were chosen for complete genome sequencing. A phylogenetic analysis revealed that the cluster of gibbon strains in this study was distinct from strains previously reported from other countries. In the pre-S1 region, we found a unique amino acid residue substitution (P89K), three insertions between T87 and L88 in the genomes of three gibbons, and a 33-nucleotide deletion at the start of pre-S1 that is common in non-human primates. The caretaker sample was identified as HBV subgenotype B3, the most common type in Indonesia. For the complete HBV sequences, the similarity between gibbons in this study and other non-human primate and human HBV isolates was 90-91.9 % and 85.5-89.6 %, respectively. In conclusion, the gibbon HBV genotype was influenced by geographic location and species. To the best of our knowledge, this is the first report characterizing the HBV genes and genomes of indigenous gibbons in Indonesia.

    This study was undertaken to determine the level of 16 polycyclic aromatic hydrocarbon (PAH), listed as priority pollutants by the United States Environmental Protection Agency (USEPA), in surface soils around a coal-transporting facility in the western part of South Kalimantan, Indonesia. Three composite soil samples were collected from a coal stockpile, coal-hauling road, and coal port. Identification and quantification of PAH was performed by gas chromatography-mass spectrometry. The total content of 16 USEPA-PAH ranged from 11.79 to 55.30 mg/kg with arithmetic mean value of 33.14 mg/kg and median of 32.33 mg/kg. The 16 USEPA-PAH measured levels were found to be greater compared with most of the literature values. The levels of high molecular-weight PAH (5- and 6-ring) were dominant and formed 67.77-80.69 % of the total 16 USEPA-PAH The most abundant of individual PAH are indeno[1,2,3-cd] pyrene and benzo[a]pyrene with concentration ranges of 2.11-20.56 and 1.59-17.84 mg/kg, respectively. The degree of PAH contamination and subsequent toxicity assessment suggest that the soils of the study area are highly contaminated and pose a potential health risk to humans.

    To investigate the characteristics of gas emissions from a tropical peatland fire, ground-level measurement of fire-generated gases was conducted during a large fire event in Kalimantan, Indonesia in 2009. Concentrations of CO and CH4 showed positive linear correlations with that of CO2. The relationship between concentrations of N2O and CO2 were divided into two parts, suggesting the influence of additional N2O generation during sample storage. The CO2-normalized emission ratio was calculated for CO, CH4, and N2O. The molar ratio of these fire-generated gas emissions was summarized as CO2:CO:CH4:N2O = 1.00:0.382:0.0261:0.000156, whereas the emission ratio calculated on the global warming potential (GWP) basis was CO2:CH4:N2O = 1.00:0.237:0.0465. The GWP emission based on this ratio was 87.8-91.2% of a simple evaluation in which all carbon was assumed to be emitted as CO2. This is the first trial to evaluate the emission ratios of major greenhouse gases on the basis of ground-level observation during an actual tropical peatland fire.

    When peat forest fires happen, it leads to burn soil and also humic acids as a dominant organic matter contained in peat soil as well as the forest. The structure and properties of humic acids vary depending on their origin and environment, therefore the transformation of humic acid is also diverse. The impacts of the peat fires on peat soil from Central Kalimantan, Indonesia were investigated through the characterization of humic acids, extracted from soil in burnt and unburnt sites. The characterization of humic acids was performed by elemental composition, functional groups, molecular weight by HPSEC, pyrolysate compounds by pyrolysis-GC/MS, fluorescence spectrum by 3DEEM spectrofluorometer, and thermogravimetry. The elemental composition of each humic substance indicated that the value of H/C and O/C of humic acids from burnt sites were lower than that from unburnt sites. The molecular weight of humic acids from burnt sites was also lower than that from unburnt sites. Pyrolysate compounds of humic acids from unburnt sites differed from those of humic acids from burnt soil. The heating experiment showed that burning process caused the significant change in the properties of humic acids such as increasing the aromaticity and decreasing the molecular weight.

    Concentrations, spatial distribution, and sources of 16 polycyclic aromatic hydrocarbons (PAHs), listed as priority pollutants by the United States Environmental Protection Agency (USEPA), were investigated in surface soils of three different coal stockpile, agricultural, and residential sites in South Kalimantan Province, Indonesia. Total PAHs concentration ranged from 4.69 to 22.67 mg kg(-1)-dw. PAHs concentrations in soil of coal stockpile sites were higher than those in agricultural and residential soil. A complex of petrogenic origin and pyrolytic sources was found within the study area, as suggested by the isomeric ratios of PAHs. The results of principal component analysis and multiple linear regressions (PCA/MLR) showed that three sources contributed to the PAHs in the study area, including biomass and coal combustion (48.46%), raw coal (35.49%), and vehicular emission (16.05%). The high value of total benzo[a]pyrene equivalent concentration (B[a]Peq) suggests that local residents are exposed to a high carcinogenic potential.

    Extractive reserves in tropical rain forests, in which only non-timber products are harvested, have been heralded by some conservationists as a means of maintaining biodiversity while providing income for local people. The study of extraction systems in Peten, Guatemala, and in West Kalimantan, Indonesia, leads to a more tempered conclusion, for while the Peten program was quite successful, the Kalimantan program was not. The study finds the success of an extractive reserve to be contingent on: (1) ecological conditions, and (2) socioeconomic and political factors. Although the study focuses on market-oriented extractive reserves, many of the issues discussed apply as well to other land uses such as the collection of non-timber forest products for household consumption or small-scale timber extraction.

    The Mahakam River delta is a tide- and wave-dominated delta located on the edge of the Kutei basin, eastern Kalimantan, Borneo. It is a coastal deltaic sequence, Neogene to Holocene in age, from which all recoverable hydrocarbons (crude oil and natural gas) are considered to be derived from kerogen III predecessors. However, a complete understanding of the types of sediments sourcing the hydrocarbons has not yet been achieved. A vibracoring program sampled the principal fine-grained depositional environments in two transects; one within the fluvially-dominated regime, one within the tidally-dominated regime. Ten sedimentary facies are distinguished and phytoclasts have been recovered from all environments of deposition. Canopy parts from the mixed tropical forest community are preserved throughout the delta, whereas dicotyledonous angiosperm mangroves are restricted to the subtidal zone and delta front. Nypa parts are preserved in most depositional environments. In sites where there appears to be an absence of macrodetritus, dispersed cuticle is recoverable. Identifiable plant parts include wood and fibrous tissues, Nypa petioles and leaf laminae, dicotyledonous angiosperm leaves and isolated cuticles, fruits and seeds, roots and rootlets, and moss. Dammar is found either as dispersed resin ducts or amorphous clasts. Additional biotic components found in bedded plant litters include insects, gastropods, bivalves, sand dollars, ostracods, and crabs. Fluvial channels and depositional sites associated with these systems in the delta front can be differentiated from Nypa swamps and mixed tropical hardwood-palm swamps based on their phytological components and accessory biotic elements. 39 refs., 10 figs., 3 tabs.

    A district-based audit of maternal and perinatal mortality began during 1994 in three provinces of South Kalimantan, Indonesia. Both medical and non-medical factors were documented and an effort was made to progress from merely assessing substandard care to recommending improvements in access to care and the quality of care. Extensive discussions of cases of maternal death were held during regular meetings with providers, policy-makers and community members. The sources of information included verbal autopsies with family members and medical records. Between 1995 and 1999 the audit reviewed 130 maternal deaths. The leading causes of death were haemorrhage (41%) and hypertensive diseases (32%). Delays in decision-making and poor quality of care in health facilities were seen as contributory factors in 77% and 60% of the deaths, respectively. Economic constraints were believed to have contributed to 37% of the deaths. The distance between a patient's home and a health provider or facility did not appear to have a significant influence, nor did transport problems. The audit led to changes in the quality of obstetric care in the district. Its success was particularly attributable to the process of accountability of both health providers and policy-makers and to improved working relationships between health providers at different levels and between providers and the community. With a view to the continuation and further expansion of the audit it may be necessary to reconsider the role of the provincial team, the need of health providers for confidentiality, the added benefit of facility-based audits, the need to incorporate scientific evidence into the review process, and the possible consideration of severe complications as well as deaths. It may also be necessary to recognize that village midwives are not solely responsible for maternal deaths. PMID:11984609

  6. Petrographic and anatomical characteristics of plant material from two peat deposits of Holocene and Miocene age, Kalimantan, Indonesia

    1992-01-01

    Samples from two peat-forming environments of Holocene and Miocene age in Kalimantan (Borneo), Indonesia, were studied petrographically using nearly identical sample preparation and microscopic methodologies. Both deposits consist of two basic types of organic material: plant organs/tissues and fine-grained matrix. There are seven predominant types of plant organs and tissues: roots possessing only primary growth, stems possessing only primary growth, leaves, stems/roots with secondary growth, secondary xylem fragments, fragments of cork cells, and macerated tissue of undetermined origin. The fine-grained matrix consists of fragments of cell walls and cell fillings, fungal remains, spores and pollen grains, and resin. Some of the matrix material does not have distinct grain boundaries (at ??500) and this material is designated amorphous matrix. The major difference between the Holocene peat and Miocene lignite in reflected light, oil immersion is a loss of red coloration in the cell walls of tissue in the lignite, presumably due to loss of cellulosic compounds. In addition, cortex and phloem tissue (hence primary roots and stems) are difficult to recognize in the lignite, probably because these large, thin-walled tissues are more susceptible to microbial degradation and compaction. Particle size in both peat and lignite samples display a bimodal distribution when measurements are transformed to a - log2 or phi (??), scale. Most plant parts have modes of 2-3?? (0.25 - 0.125 mm), whereas the finer-grained particulate matrix has modes of 7-9?? (0.008-0.002 mm). This similarity suggest certain degradative processes. The 2-3?? range may be a "stable" size for plant parts (regardless of origin) because this is a characteristics of a substrate which is most suitable for plant growth in peat. The finer-grained matrix material (7-9??) probably results from fungal decay which causes plant material to weaken and with slight physical pressure to shatter into its component

    Tropical peatland in Southeast Asia is a vast reservoir of terrestrial carbon, which covers 24.8 million hectares and stores 68.5 PgC peat, equal to 11-14% of global peat carbon. In recent decades, large scale peatland fire has occurred frequently in that region, in which many areas of peatland were reclaimed with intention to use the land for forest plantation and rice paddy. We conducted a plot-scale peat burning experiment to elucidate the characteristics of gaseous carbon emission from a tropical peatland fire at the ground level. The experimental site was established at an open area 20 km southeast from Palangka Raya, Central Kalimantan Province, Indonesia. The size of the burning plot is 4 m in length and 3 m in width. Gas samples were collected at heights of 1.0, 0.5, 0.0 (aboveground), -0.1 and -0.2 m (belowground) through stainless steel and/or aluminum tubes settled across the edge of the plot. The concentrations of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4) and particulate matter (PM) was determined. Soil temperature was recorded every 10 minutes 0.1 and 0.2 m below the ground surface. Twelve iron rods were installed in 1-m by 1-m square grid to determine the depth of burn scar. After ignition, flaming stage of peat burning was ceased within 1-2 hours. The following smoldering stage continued for a week. In the flaming stage, soil temperature at -0.1 m increased tentatively. After the smoldering stage began, the temperature rapidly increased to 350-450°C. Response of soil temperature at -0.2 m was less prominent. Concentrations of gaseous components became maximal in the flaming stage. During the smoldering stage, the concentrations gradually decreased. The influence of burning on CO2 and PM was prominently remained at -0.1 m, whereas those at -0.2 m were not so much. The averaged burnt depth was 5.8±5.1 cm. Based on bulk density of 0.22 g/cm3 and carbon content of 55.5%, the amount of carbon lost from the plot was 85.3 kg. Most of the

    A 9.5 m core from an inland peatland in Kalimantan, Indonesia, reveals organic matter accumulation started around 26 000 cal. yr BP, providing the oldest reported initiation date for lowland ombrotrophic peat formation in SE Asia. The core shows clear evidence for differential rates of peat formation and carbon storage. A short period of initial accumulation is followed by a slow rate during the LGM, with fastest accumulation during the Holocene. Between 13 000 and 8000 cal. yr BP, > 450 cm of peat were deposited, with highest rates of peat (> 2 mm yr-1) and carbon (> 90 g C m-2yr-1) accumulation between 9530 and 8590cal.yrBP. These data suggest that Kalimantan peatlands acted as a large sink of atmospheric CO2 at this time. Slower rates of peat (0.15-0.38mmyr-1) and carbon (7.4-24.0gCm-2yr-1) accumulation between 8000 and 500cal.yrBP coincide with rapid peat formation in coastal locations elsewhere in SE Asia. The average LORCA (long-term apparent carbon accumulation rate) for the 9.5m core is 56gCm-2yr-1. These data suggest that studies of global carbon sources, sinks and their dynamics need to include information on the past and present sizeable peat deposits of the tropics. Copyright

    The bulk organic matter composition (total organic carbon (TOC) content and δ13CTOC) and composition of isoprenoid and branched glycerol dialkyl glycerol tetraethers (GDGT) in surface sediments from 43 stations in the Berau River delta (east Kalimantan, Indonesia), including two coast-shelf transects and stations within the river mouth, were examined to reveal the spatial heterogeneity in these parameters in order to assess the impact of a tropical river loaded with suspended matter on the sedimentary organic matter in the shelf system. The high-resolution study showed that, despite the extensive transport of eroded soil material by the river to the sea, terrestrial organic matter and brGDGTs are only deposited on a relatively small part of the shelf. The concentrations of brGDGTs are highest (up to 120 μg g-1 TOC) in sediments deposited in and close to the mouth of the Berau River and their distribution indicates that they represent a mixture of soil-derived and river in-situ produced brGDGTs. Crenarchaeol concentrations reach 700 μg g-1 TOC in sediments deposited on the outer shelf due to Thaumarchaeotal production in shelf waters. This results in a strong gradient (0.93-0.03) in the BIT index, with high values in the river mouth and low values on the shelf. The decline in the BIT index is caused by both decreasing concentrations of the brGDGTs and increasing concentrations of crenarchaeol. The BIT index shows a highly significant but non-linear relationship with δ13CTOC. On the shelf, in the area not under the direct influence of the Berau River, cyclic brGDGTs become relatively dominant, most probably due to in-situ production in the alkaline pore waters of the surface sediments. The spatial heterogeneity of sources of brGDGTs on the Berau shelf complicates the use of brGDGTs as temperature proxies. Application of the global soil calibration to sedimentary mixtures of brGDGTs in the river-influenced area of the shelf results in a severe underestimation of

    Platinum-group minerals occur in significant proportions in placer deposits in several localities in South Kalimantan. They consist of Pt-Fe alloy that may be intergrown with or contain inclusions of Ir-Os-Ru alloy, laurite and chromite. Alluvial PGM found along Sungai Tambanio are in part derived from chromatite schlieren in dunitic bodies intruded into clinopyroxene cumulates that may be part of an Alaskan-type ultramafic complex. A chromitite schlieren in serpentinite from one of these dunitic bodies is anomalous in PGE. The chondrite-normalized PGE pattern for this rock, pan concentrates from this area, and PGM concentrates from diamond-Au-PGM placer deposits have an "M'-shaped pattern enriched in Ir and Pt that is typical of PGE-mineralization associated with Alaskan-type ultramafic complexes. -Authors

    In an earlier study we found that there is a habit of mixing boiled and unboiled water to prepare drinks, particularly cold tea, in South Kalimantan, Indonesia. Ulamas (Islamic religious leaders) have a very influential role in that community. This study was designed to implement and evaluate a health educational campaign using local ulamas. Three study communities were selected. The first intervention area received education through Al Quran (Koranic) reading clubs. In the second area the intervention was implemented by home visits as well as by Al Quran reading clubs, since participation in Al Quran reading clubs was low. The third area served as the control. A message and intervention development was designed by the ulamas and the investigators using sarasehan (ulamas' meeting). A positive impact on knowledge and practices of drinking water preparation was observed in the first area where the community members were active participants in the Al Quran reading club. Involving ulamas in a health education campaign was indicated to be effective in changing knowledge and practices.

    Industrial agricultural plantations are a rapidly increasing yet largely unmeasured source of tropical land cover change. Here, we evaluate impacts of oil palm plantation development on land cover, carbon flux, and agrarian community lands in West Kalimantan, Indonesian Borneo. With a spatially explicit land change/carbon bookkeeping model, parameterized using high-resolution satellite time series and informed by socioeconomic surveys, we assess previous and project future plantation expansion under five scenarios. Although fire was the primary proximate cause of 1989–2008 deforestation (93%) and net carbon emissions (69%), by 2007–2008, oil palm directly caused 27% of total and 40% of peatland deforestation. Plantation land sources exhibited distinctive temporal dynamics, comprising 81% forests on mineral soils (1994–2001), shifting to 69% peatlands (2008–2011). Plantation leases reveal vast development potential. In 2008, leases spanned ∼65% of the region, including 62% on peatlands and 59% of community-managed lands, yet <10% of lease area was planted. Projecting business as usual (BAU), by 2020 ∼40% of regional and 35% of community lands are cleared for oil palm, generating 26% of net carbon emissions. Intact forest cover declines to 4%, and the proportion of emissions sourced from peatlands increases 38%. Prohibiting intact and logged forest and peatland conversion to oil palm reduces emissions only 4% below BAU, because of continued uncontrolled fire. Protecting logged forests achieves greater carbon emissions reductions (21%) than protecting intact forests alone (9%) and is critical for mitigating carbon emissions. Extensive allocated leases constrain land management options, requiring trade-offs among oil palm production, carbon emissions mitigation, and maintaining community landholdings. PMID:22523241

    Understanding the complex relationship between primates and their habitats is essential for effective conservation plans. Peat-swamp forest has recently been recognized as an important habitat for the Southern Bornean gibbon (Hylobates albibarbis), but information is scarce on the factors that link gibbon density to characteristics of this unique ecosystem. Our aims in this study were firstly to estimate gibbon density in different forest subtypes in a newly protected, secondary peat-swamp forest in the Sabangau Catchment, Indonesia, and secondly to identify which vegetation characteristics correlate with gibbon density. Data collection was conducted in a 37.1 km(2) area, using auditory sampling methods and vegetation "speed plotting". Gibbon densities varied between survey sites from 1.39 to 3.92 groups/km(2). Canopy cover, tree height, density of large trees and food availability were significantly correlated with gibbon density, identifying the preservation of tall trees and good canopy cover as a conservation priority for the gibbon population in the Sabangau forest. This survey indicates that selective logging, which specifically targets large trees and disrupts canopy cover, is likely to have adverse effects on gibbon populations in peat-swamp forests, and calls for greater protection of these little-studied ecosystems.

    Mud volcanoes often release fluids in a pulsating fashion, with periodic timescales ranging from minutes to days. These oscillations, common in natural systems of multi-phase fluid flow, are thought to result from some combination of complex feedback mechanisms between conduit and source geometry, and such factors as: fluid compressibility, viscosity and density, changes in lithostatic stresses, reservoir pressure, or vent conditions. The LUSI mud volcano is in a densely populated district of the Sidoarjo regency (East Java, Indonesia), and has been erupting since May 2006. Crisis management workers and local residents have reported observations of pulsating eruptive cycles lasting a few hours during the first two years of the eruption, and possibly beyond. Since 2010, however, the activity has shifted to individual transient eruptions recurring at intervals of a few minutes. In the summer of 2011, we documented this cyclic behavior at LUSI using a combination of high-resolution time-lapse photography, webcam, and thermal infrared imagery. The imagery reveals that hot mud and gases were released from three individual sources within the 150 m wide vent pond. The mud, consisting of at least 70% water, is erupted at temperatures close to boiling. Released gases consist principally of water vapor, carbon dioxide and methane. Eruptions ejected mud some 20 m above the vent in an unsteady fountain and formed 50 m-high plumes of hot gas. Pulses, on average 50 s in duration, were characterized by sharp onsets and exponential decays in intensity. We observed explosion periods ranging from 1 to 3 minutes during this campaign, the median period was 100 s, and pulses were separated by periods of apparent quiescence. Each vent was characterized by a different dominant period, indicating that parameters controlling activity vary among the vents. Potential conceptual eruptive models are gas accumulation and release, slug flow, or oscillations in pressure at depth to account for

    The western Sulawesi magmatic belt and the Sunda-Banda arc define the eastern and south-eastern margins of Sundaland, which is part of the relatively stable Eurasian plate. The eastern margin is bounded by the Makassar Strait which separates western Sulawesi from Kalimantan. The initial opening of the Makassar Strait took place in the late Cretaceous-Early Tertiary leading to the opening of the Pacific-Indian Ocean gateway during Neogene time. Recent studies indicate similarities in the late Cretaceous-Paleogene stratigraphic sequence and calc-alkali magmatism between Sumba, south Sulawesi and south-east Kalimantan, suggesting a Sundaland origin for all of these areas. The southward migration of Sumba to the present frontal arc position of the Sunda-Banda arc has occurred since Late Cretaceous-Paleocene time.

    Universal childhood hepatitis B vaccination was introduced in Indonesia in 1997; by 2008, coverage was estimated to be 78%. This study aimed to investigate the serologic status and virologic characteristics of hepatitis B virus (HBV) among the children in East Java. A total of 229 healthy children born during 1994-1999 were enrolled in this study. Overall, 3.1% were positive for hepatitis B surface antigen (HBsAg) and 23.6% were positive for antibody to HBsAg (anti-HBs). HBV DNA was detected in 5 of 222 HBsAg-negative carriers, which were suggested to be cases of occult HBV infection. A single amino substitution (T126I) in the S region was frequently found. HBV infection remains endemic, and the prevalence of anti-HBs remains insufficient among children in East Java, Indonesia.

    Peat fires in Southeast Asia have become a major annual source of trace gases and particles to the regional-global atmosphere. The assessment of their influence on atmospheric chemistry, climate, air quality, and health has been uncertain partly due to a lack of field measurements of the smoke characteristics. During the strong 2015 El Niño event we deployed a mobile smoke sampling team in the Indonesian province of Central Kalimantan on the island of Borneo and made the first, or rare, field measurements of trace gases, aerosol optical properties, and aerosol mass emissions for authentic peat fires burning at various depths in different peat types. This paper reports the trace gas and aerosol measurements obtained by Fourier transform infrared spectroscopy, whole air sampling, photoacoustic extinctiometers (405 and 870 nm), and a small subset of the data from analyses of particulate filters. The trace gas measurements provide emission factors (EFs; grams of a compound per kilogram biomass burned) for up to ˜ 90 gases, including CO2, CO, CH4, non-methane hydrocarbons up to C10, 15 oxygenated organic compounds, NH3, HCN, NOx, OCS, HCl, etc. The modified combustion efficiency (MCE) of the smoke sources ranged from 0.693 to 0.835 with an average of 0.772 ± 0.053 (n = 35), indicating essentially pure smoldering combustion, and the emissions were not initially strongly lofted. The major trace gas emissions by mass (EF as g kg-1) were carbon dioxide (1564 ± 77), carbon monoxide (291 ± 49), methane (9.51 ± 4.74), hydrogen cyanide (5.75 ± 1.60), acetic acid (3.89 ± 1.65), ammonia (2.86 ± 1.00), methanol (2.14 ± 1.22), ethane (1.52 ± 0.66), dihydrogen (1.22 ± 1.01), propylene (1.07 ± 0.53), propane (0.989 ± 0.644), ethylene (0.961 ± 0.528), benzene (0.954 ± 0.394), formaldehyde (0.867 ± 0.479), hydroxyacetone (0.860 ± 0.433), furan (0.772 ± 0.035), acetaldehyde (0.697 ± 0.460), and acetone (0.691 ± 0.356).

    Indonesia, an archipelago of 13,500 islands, ranks 5th as the most populous nation in the world. It has 175 million people, 105 million of which live on the island of Java alone. Indonesia has many distinct cultural and linguistic groups. Islam almost wholly replaced Hindu by the end of the 16th century, after arriving in the 12th century. Today 88% of the people are Muslim, while the rest includes Christians, Hindus, Buddhists, and others. The constitution guarantees religious freedom. Indonesia gained independence from the Netherlands in 1949. Indonesia's 1st president, Sukarno, led the rebellion leading to independence and remained in power from 1949-1967. After aligning with Asian communist countries and establishing an authoritarian regime in the early 1960s, the people rebelled, attempted a coup and, in 1967, the People's,s Consultative Assembly named Soeharto as president. He continues to be Indonesia's president and the dominant government and political figure. The constitution provides limited separation of executive, legislative, and judicial power. During the 1970s, the strong economy was based on high oil revenues and an industrial policy which protected domestic industries. Beginning in the 1980s, however, lower energy earnings assisted by low inflation, a downward float against the dollar, and the government eliminating regulatory obstacles turned the economic tide. Even though Indonesia has a larger unrescheduled external debt than any other developing nation, the government is dealing successfully with servicing this debt. Foreign interests participate in the oil and minerals sectors. Indonesia acts on its free and active foreign policy by playing a prominent role in Asian affairs, but avoiding involvement in conflicts among major powers. Indonesia is on friendly terms with its neighbors, and the military does not advocate developing the capability to project its power.

    A detailed structural and stratigraphic study of a deep water (>200 m) sub-basin in the East Java Sea utilized 2-D seismic and well log data in the vicinity of four Amoco wildcats drilled in the early 1980's. A pelitic basement was deformed in an accretionary prism during the Cretaceous and uplifted and peneplained during the early Tertiary. Extensional half-grabens trending ENE with respect to present geography formed in the Sunda back-arc during the middle Eocene to early Oligocene. The basin- bounding faults are highly listric and are inferred to sole into a sub-horizontal detachment at a depth of less than 10 km. The location and orientation of the extensional structures was strongly controlled by pre-existing thrusts and shaly bedding planes within basement. Isochron maps show Eocene rifting to be localized in a few deep basins, and Oligocene rifting to be more broadly distributed in shallower basins. Inversion began during the early Miocene as listric basin-bounding faults were reactivated in a compressional mode and graben-filling sediments were displaced towards adjacent horst blocks. Most inversions trend ENE with respect to present geography and have grown in bathyal water depths by differential subsidence due to tectonic loading of paleo-horst blocks. Inversion progressed throughout the Miocene and culminated in the development of a regional basement-involved inversion high (eastern extension of Kangean high) which was uplifted and truncated in the latest Miocene. Despite regional compression which continues today at a deep structural level, small-displacement domino-style normal faults are ubiquitous at a shallow structural level and apparently form on the flanks of the growing inversions by a gravity sliding mechanism.

    A detailed structural and stratigraphic study of a deep water (>200 m) sub-basin in the East Java Sea utilized 2-D seismic and well log data in the vicinity of four Amoco wildcats drilled in the early 1980`s. A pelitic basement was deformed in an accretionary prism during the Cretaceous and uplifted and peneplained during the early Tertiary. Extensional half-grabens trending ENE with respect to present geography formed in the Sunda back-arc during the middle Eocene to early Oligocene. The basin- bounding faults are highly listric and are inferred to sole into a sub-horizontal detachment at a depth of less than 10 km. The location and orientation of the extensional structures was strongly controlled by pre-existing thrusts and shaly bedding planes within basement. Isochron maps show Eocene rifting to be localized in a few deep basins, and Oligocene rifting to be more broadly distributed in shallower basins. Inversion began during the early Miocene as listric basin-bounding faults were reactivated in a compressional mode and graben-filling sediments were displaced towards adjacent horst blocks. Most inversions trend ENE with respect to present geography and have grown in bathyal water depths by differential subsidence due to tectonic loading of paleo-horst blocks. Inversion progressed throughout the Miocene and culminated in the development of a regional basement-involved inversion high (eastern extension of Kangean high) which was uplifted and truncated in the latest Miocene. Despite regional compression which continues today at a deep structural level, small-displacement domino-style normal faults are ubiquitous at a shallow structural level and apparently form on the flanks of the growing inversions by a gravity sliding mechanism.

    We describe Cyrtodactylus hitchi sp. nov., a new species of Bent-toed Gecko from montane forests in the Mekongga Mountains, South East Sulawesi, Indonesia. Although we cannot speculate about relationships, morphologically it shares several traits with C. batik, a large species known only from Mount Tompotika near the tip of Sulawesi's Eastern Peninsula. The following unique combination of characters distinguishes it from all other congeners: absence of precloacal groove, absence of precloacal and femoral pores, absence of enlarged femoral scales, no abrupt contact between large and small postfemoral scales, 18-20 lamellae under the fourth toes, and transversely enlarged, median subcaudal scales arranged in a single row.

    This discussion of Indonesia focuses on the following: geography; the people; history; government and political conditions; the economy; foreign relations; defense; and relations between Indonesia and the US. In 1985, Indonesia's population totaled 173 million with an annual growth rate of 2.1%. Infant mortality was 89/1000 and life expectancy 55 years. The Republic of Indonesia is an archipelago of more than 13,500 islands extending 4800 kilometers along the equator from the mainland of Southeast Asia to Australia. Indonesians are primarily of Malay stock and include many related but distinct cultural and linguistic groups. Republic based on the 1945 constitution providing for limited separation of executive, legislative, and judicial power. The president, elected for a 5-year term, is the dominant government and political figure. Over the 1983-85 period, Indonesia experienced much success in stabilizing the economy following a downturn in 1981-82. Indonesia cut government expenditures, devalued the rupiah by 28% vis-a-vis the US dollar, and introduced a financial reform package to improve efficiency in the banking system and to encourage savings. Real gross domestic product (GDP) grew 4.2% in 1983 and 6% in 1984; inflation fell from 12% in 1983 to 9% in 1984 and 4% during the 1st part of 1985; the current account deficit declined from 8% to 3% of GDP by 1984. Agriculture is the most important domestic sector, accounting for more than 25%. The manufacturing sector accounts for 12% of GDP. Since the beginning of the Soeharto government, US relations with Indonesia have been close and cordial. PMID:12233540

    The Brantas is one of Indonesia's most important catchments. It is the "rice bowl" of Java and nationally important for its industrial activity. Surabaya, Indonesia's second largest city, is located at the mouth of the Brantas River which is pivotal to the city's water supply. The challenges associated with the institutional framework for natural resource management in East Java parallels that of many states and provinces around the globe. It is multi-layered and complex. Integrated Catchment Management (ICM) may be defined as "the co-ordinated and sustainable management of land, water, soil vegetation, fauna and other natural resources on a water catchment basis". Over a period of six months, an ICM Strategy was researched and facilitated for the Brantas River Catchment in East Java via a short term advisor attachment. The aim of the Strategy is to improve coordination, co-operation, communication and consistency of government and community efforts towards sustaining the catchment's environmental, economic and social values. The attachment was part of the Pollution Control Implementation (PCI) Project funded by AusAid and the Indonesian Government. The ICM Strategy developed was broad based and addressed the priority natural resource management issues facing the Brantas Catchment. It was co-ordinated by BAPEDALDA, the Provincial Environmental Protection Agency, and developed by all agencies involved in natural resource management in the catchment. Various Universities and Non Government Organisations (NGOs) were also involved in the ICM process which developed the Strategy. At the conclusion of the attachment, a draft ICM Strategy and a proposed institutional framework had been developed. A working group of key agencies was also established to further enhance local "ownership", finalise timescales and implementation responsibilities within the Strategy and bring the institutional arrangements into being through a Governor's Decree.

    The U.S. is recognized globally for its leadership in science and technology. Scientific cooperation is an important tool in the application of "smart power" to create partnerships with countries around the world. The State Department's Office of the Science Advisor works to increase the number of scientists engaged in diplomacy through coordination with the American Association of the Advancement of Science, Science Diplomacy Fellows, Jefferson Science Fellowships, and the Embassy Science Fellows Program. In addition, scientific cooperation occurs at all levels through relationships between science faculties, scientific institutions, and technical assistance programs. President Obama made increased collaboration on science and technology, the appointment of new science envoys, and the opening of new scientific centers of excellence in Africa, and the Middle East, and Southeast Asia a central component of his Cairo speech. Indonesia, science diplomacy crosses myriad programs. Negotiations on a bilateral Science and Technology Agreement between the U.S. and Indonesia will begin in September. USAID provides assistance in volcano/earthquake monitoring, forest management and reduction of illegal logging with DOJ, clean water and sanitation, the Coral Triangle Initiative to sustain Indonesia's marine biodiversity, coastal resilience with NOAA, clean energy, clean air initiatives with EPA, and emergency disaster response. The LUSI mudflow disaster, located just 27 km south of the U.S. Consulate in Surabaya, has already displaced thousands, has contributed to environmental degradation, and threatens critical transportation infrastructure. U.S. assistance to Indonesia to mitigate the impact of the LUSI mudflow on surrounding communities and the environment was complicated by questions surrounding the cause of the mud: industrial accident or natural disaster. But, the devastating impact on the local environment, population, and businesses was unquestioned. Experts from the

  9. Coalbed methane: A partial solution to Indonesia`s growing energy problems

    Indonesia contains the largest resources of coal in Southeast Asia. Indonesian scientists estimate that the in-place coalbed methane resource in 16 onshore basins is about 213 Tcf ({approximately}6 Tcm). This volume is approximately double Indonesia`s current reserves of natural gas. Indonesia is a rapidly industrializing nation of 186 million people, of which 111 million live in Java and 38 million in Sumatra. As industrialization progresses from the present low level, the growth in energy demand will be very rapid. Indonesia`s domestic gas demand is expected to increase form 1.6 Bcf/d (0.05 Bcm/d) in 1991 to 5.7 Bcf/d (0.2 Bcm/d) in 2021. Because the major gas resources of East Kalimantan, North Sumatra, and Natuna are so remote from the main consuming area in northwest Java and are dedicated for export by virtue of the national energy policy, the need is becoming urgent to develop new resources of natural gas, including coalbed methane, for the domestic market. Due to the high geothermal gradient, the coal deposits in the back-arc basins of Sumatra and Java are expected to be of higher than normal rank at depths favorable for coalbed methane production. The oil- and gas-productive Jatibarang sub-basin in northwest Java, with estimated in-place resources of coalbed methane in excess of 20 Tcf (0.6 Tcm), is considered to be the most prospective area in Indonesia for the near-term development of coalbed methane. This area includes Jakarta and vicinity, the most populous and most heavily industrialized part of Indonesia.

    Japanese encephalitis virus (JEV) is a fatal disease in Asia. Pigs are considered to be the effective amplifying host for JEV in the peridomestic environment. Bali Island and Java Island in Indonesia provide a model to assess the effect of pigs on JEV transmission, since the pig density is nearly 100-fold higher in Bali than Java, while the geographic and climatologic environments are equivalent in these areas. We surveyed antibodies to JEV among 123 pigs in Mengwi (Bali) and 96 pigs in Tulungagung (East Java) in 2008 by the hemagglutination-inhibition (HAI) test. Overall prevalences were 49% in Bali and 6% in Java, with a significant difference between them (P < 0.001). Monthly infection rates estimated from age-dependent antibody prevalences were 11% in Bali and 2% in Java. In addition, 2-mercaptoethanol-sensitive antibodies were found only from Bali samples. Further, the average HAI antibody titer obtained from positive samples was significantly higher in Bali (1:52) than Java (1:10; P < 0.001). These results indicated that JEV transmission in nature is more active in Bali than East Java.

    By using GNSS (Global Navigation Satellite Systems) receiver to collect amplitude scintillation at L1 frequency from GPS and GLONASS, we investigated ionospheric scintillation occurrence at equator anomaly in Indonesia from July 2014 to June 2015. The receiver is installed at Bandung (6.9 deg S, 107.6 deg E; 9.9 deg S mag. latitude), Indonesia. In this study, we grouped our analysis into two groups based on duration of observation, (1) July-December 2014 (monthly F10.7 ranged from 124.7-158.7) which is named autumn equinox and (2) January-June 2015 (monthly F10.7 ranged from 120.1-141.7) which is named spring equinox. Our preliminary results can be summarized as follows; (1) the intensity of scintillations at spring equinox is higher than at autumn equinox although solar activity at autumn equinox is higher than at spring equinox, see Figure 1 and (2) as shown in Figure 2, the directional distribution of scintillation occurrences at spring equinox mostly concentrate in the western sky, so we see east-west asymmetric, but the distribution at autumn equinox doesn't show clearly east-west asymmetric. Previous studies have reported that occurrence rate of the scintillation at spring equinox season is higher than at autumn equinox. Our results suggest that equinoctial asymmetry of scintillation occurrence can be also as an asymmetric of scintillation intensity and east-west asymmetric of scintillation occurrence between spring and autumn equinox. In general, plasma bubble is tilted westward as it vertically develop due to vertical shear in the eastward plasma drift in F region, and consequently, it will be tilted westward as it extends in latitude. Scintillation intensity will be stronger when signal propagation tend to be parallel with structure of the plasma bubble. Figure 2 also imply that the latitudinal extension of plasma bubble is higher at spring equinox than at autumn equinox. More the bubble extends in latitude, more the bubble structure exists in the western

    Oil palm supplies >30% of world vegetable oil production. Plantation expansion is occurring throughout the tropics, predominantly in Indonesia, where forests with heterogeneous carbon stocks undergo high conversion rates. Quantifying oil palm's contribution to global carbon budgets therefore requires refined spatio-temporal assessments of land cover converted to plantations. Here, we report oil palm development across Kalimantan (538,346km2) from 1990 to 2010, and project expansion to 2020 within government-allocated leases. Using Landsat satellite analyses to discern multiple land covers, coupled with above- and below-ground carbon accounting, we develop the first high-resolution carbon flux estimates from Kalimantan plantations. From 1990 to 2010, 90% of lands converted to oil palm were forested (47% intact, 22% logged, 21% agroforests). By 2010, 87% of total oil palm area (31,640km2) occurred on mineral soils, and these plantations contributed 61-73% of 1990-2010 net oil palm emissions (0.020-0.024GtCyr-1). Although oil palm expanded 278% from 2000 to 2010, 79% of allocated leases remained undeveloped. By 2020, full lease development would convert 93,844km2 (~ 90% forested lands, including 41% intact forests). Oil palm would then occupy 34% of lowlands outside protected areas. Plantation expansion in Kalimantan alone is projected to contribute 18-22% (0.12-0.15GtCyr-1) of Indonesia's 2020 CO2-equivalent emissions. Allocated oil palm leases represent a critical yet undocumented source of deforestation and carbon emissions.

    Defining the spectrum of specific thalassemia mutations is an important issue when planning prevention programs in large multi ethnic countries as is Indonesia. In a first attempt to define the prevalence of the common mutations in East Java we selected a cohort of 17 transfusion-dependent patients attending the Dr. Soetomo Hospital, Surabaya, Indonesia. After basic diagnostics we performed direct DNA sequencing for all β-globin genes. The results obtained on 34 independent chromosomes revealed the following prevalence rates: c.79 G>A p. Glu27Lys (Hb E) 47.0%; c.92+5G>C (IVS-I-5 G>C) 20.6%; c.109_110 delC p.Pro37Leu fs X7 [codon 35 (-C)] 17.6%; c.46del T p.Trp16Gly fsX4 [codon 15 (-T)] 5.9%; c.126_129delCTTT p.

Our preliminary results show that the distribution of the prevalent mutations in our cohort is quite homogeneous but with different forms than previously reported. This indicates that more studies on a larger scale and in different geographical areas are needed to refine our provisional results and to characterize the molecular background of the disease in the whole country.

WHO is clariafy that road accident level in the world have to reach 1.2 mellion victim death and over 30 mellion injuries every year. As much 85% sacrifice death are accident in develop state, where vehicle number only 32% from vehicle number in the world. That becouse as the objective is to decide influence road charakteristics geometrics for motorcycle accident in Batu East Java Indonesia. Using some statistical analysis it is found that the best-fit motorcycle accident model is: Acc = 0,009F0,703exp(-0,334SW-0,361G+0.077S) Where: Acc = number of accident, F = Flow, pcu/hr, SW = shoulder width (m), S = speed, km/hr, G = Gradient (0,1) The model shows that the affecting factors are flow, shoulder width and speed, therefore local government should improve some related factor (flow, shoulder width, Gradient and speed) that can reduce the number of motorcycle accident at crossing road in Batu.

    Malaria has long been known as one of the major public health problems in West Sumba District, East Nusa Tenggara Province, Indonesia. To obtain baseline data for establishment of a suitable malaria control program in the area, malariometric surveys were conducted in two sub-districts, Wanokaka and Loli, during the periods of January, May, and August 2005. The survey included three selected villages in each sub-district, and blood smear analyses of 701, 921, and 894 randomly selected subjects in January, May, and August revealed 30.5%, 25.3%, and 28.2% malaria positives, respectively, consisting mainly of Plasmodium falciparum and P. vivax, and in a few cases, P. malariae. Analysis of malaria prevalence at different age groups clearly reflected the common phenomenon that younger individuals are more vulnerable by infection of either P. falciparum or P. vivax. In falciparum malaria, the frequency of cases carrying gametocytes was also relatively high involving all age groups. The findings indicate that the malaria incidence and transmission in the area are relatively high and that further exploration is warranted to establish a precise malaria control program.

    An imbricated Mesozoic to Palaeogene continental margin sequence is juxtaposed with ophiolitic rocks in the East Arm of Sulawesi, Indonesia. The two tectonic terranes are bounded by the Batui Thrust and Balantak Fault System, which are considered to be the surface expression of the collision zone between the Banggai-Sula Platform and the Eastern Sulawesi Ophiolite Belt. The collision complex contains three distinctive sedimentary sequences : 1) Triassic-Palaeogene continental margin sediments, ii) Cretaceous pelagic sediments and iii) Neogene coarse clastic sediments and volcanogenic turbidites. (i) Late Triassic Lemo Beds consisting largely of carbonate-slope deposits and subsidiary clastics including quartz-rich lithic sandstones and lensoidal pebbly mudstone and conglomeratic breccia. The hemipelagic limestones are rich in micro-fossils. Some beds of the limestone contain bivalves and ammonites, including Misolia, which typifies the Triassic-Jurassic sequence of eastern Indonesia. The Jurassic Kapali Beds are dominated by quartzose arenites containing significant amounts of plant remains and lumps of coal. The Late Jurassic sediments consist of neritic carbonate deposits (Nambo Beds and Sinsidik Beds) containing ammonites and belemnites, including Belemnopsis uhligi Stevens, of Late Jurassic age. The Jurassic sediments are overlain unconformably by Late Cretaceous Luok Beds which are predominantly calcilutite with chert nodules rich in microfossils. The Luok Beds are unconformably overlain by the Palaeogene Salodik Limestones which consist of carbonate platform sediments rich in both benthic and planktonic foraminifera of Eocene to Early Miocene age. These sediments were deposited on the continental margin of the Banggai-Sula Platform.

    Assessment of river 'health' using biological methods, particularly those based on macro-invertebrates, is now commonplace in most developed countries. However, this is not the case in most developing countries, where physical and chemical methods are used to assess water quality, with very little use of biological assessment methods. This paper reports on a project that aimed to assess the possible introduction of biological assessment of river condition using the Australian River Assessment System (AUSRIVAS) into Indonesia. The paper addresses three components of the project: (1) science--does the bioassessment method work in this tropical region? (2) resources--are they adequate and if not what additional resources are needed? (3) politics--what needs to be done to convince the agencies (both central and provincial) to take up such a new philosophy and approach? A pilot study was run in the upper Brantas River, East Java. A total of 66 reference sites and 15 test sites were sampled and the macro-invertebrates collected were identified to family level. A rigorous quality-control protocol was introduced to ensure the data were reliable and reproducible. The macro-invertebrate data were used to develop a predictive model of the AUSRIVAS type for the upper Brantas River, and the model was then used to assess the 'health' of sites that were presumed to be damaged in this section of the river. A number of difficulties were experienced during the study, including: locating reference sites sufficiently unmodified by humans; lack of skills to identify animals collected; and a paucity of facilities required for aquatic macro-invertebrate identification (e.g. identification keys and good quality binocular microscopes). For resources, the major constraint to the introduction of a bioassessment capability in Indonesia is the lack of personnel trained in the bioassessment techniques. An 'on-the-job' training approach was adopted, largely because of the specialist nature of

    Excavations at Liang Bua, a limestone cave on the island of Flores, East Indonesia, have yielded a well-dated archaeological and faunal sequence spanning the last 95k.yr., major climatic fluctuations, and two human species -H. floresiensis from 95 to 17k.yr.(1), and modern humans from 11k.yr. to the present. The faunal assemblage comprises well-preserved mammal, bird, reptile and mollusc remains, including examples of island gigantism in small mammals and the dwarfing of large taxa. Together with evidence from Early-Middle Pleistocene sites in the Soa Basin, it confirms the long-term isolation, impoverishment, and phylogenetic continuity of the Flores faunal community. The accumulation of Stegodon and Komodo dragon remains at the site in the Pleistocene is attributed to Homo floresiensis, while predatory birds, including an extinct species of owl, were largely responsible for the accumulation of the small vertebrates. The disappearance from the sequence of the two large-bodied, endemic mammals, Stegodon florensis insularis and Homo floresiensis, was associated with a volcanic eruption at 17 ka and precedes the earliest evidence for modern humans, who initiated use of mollusc and shell working, and began to introduce a range of exotic animals to the island. Faunal introductions during the Holocene included the Sulawesi warty pig (Sus celebensis) at about 7ka, followed by the Eurasian pig (Sus scrofa), Long-tailed macaque, Javanese porcupine, and Masked palm civet at about 4ka, and cattle, deer, and horse - possibly by the Portuguese within historic times. The Holocene sequence at the site also documents local faunal extinctions - a result of accelerating human population growth, habitat loss, and over-exploitation.

    The 29th of may 2006, gas water and mud breccia started to erupt at several localities along the Watukosek fault system, in the Sidoarjo Regency in East java, Indonesia. The most prominent eruption, named Lusi, is still active and covering a surface of nearly 7 km2, resulting in the displacement of ~ 30 000 people. Although the origin and the chemical composition of the erupted fluids have been documented, the mechanical and physical properties of the mud are poorly constrained, and many aspects still remain not understood. Very little is known about the internal dynamics of the Lusi conduit(s). In this study, conducted in the framework of the Lusi Lab project (ERC grant n°308126) we use both analytical and numerical methods to better understand the flow dynamics within the main conduit and to try to explain the longevity of the edifice. The 2D numerical model considers a vertical conduit with a reservoir at its base and solves the stokes equations, discretized on a finite element mesh. Although, three phases (solid, liquid and gas) are present in nature, we only consider the liquid phase. The solid phase is treated as rigid particles in suspension in the liquid. The gaseous phase (methane and carbon dioxide) is treated in an analytical manner using the equations of state of the H2O-CO2 and H2O-CH4 systems. Here, we discuss the effects of density, viscosity, gas concentration and clasts concentration and size on the dynamics of the flow in the conduit as well as implications of the conduit stability.

    Arjuno-Welirang is a twin strato-volcano system located in the East of Java (Indonesia). It features two main peaks: Arjuno (3339 masl) and Welirang (3156 masl). The last recorded eruptive activity took place in August 1950 from the flanks of Kawah Plupuh and in October 1950 by the NW part of the Gunung Welirang. This strato-volcano is characterized by a solfataric area, with high T-vent fumarole at least up to 220°C, located mainly in the Welirang crater zone where sulphur deposits are abundant. In addition, several hot springs vent from the flanks of the volcano, indicating the presence of a large hydrothermal system During July 2015 we carried out a geochemical field campaign on the Arjuno-Welirang volcano-hydrothermal system area sampling water and dissolved gases from the thermal and cold springs located on the flanks of the volcano and from two high-T fumaroles located on the summit area of Welirang. Hydrothermal springs reveal temperatures up to 53°C and pH between 6.2 and 8.2. The hydrothermal springs show a volatile content (mainly CO2 and He) that is several order of magnitude higher than the Air Saturated Waters values (ASW) indicating a strong gas/water interaction processes between waters of meteoric origin and deep volatiles of volcanic origin. The hydrothermal springs have dissolved helium isotopic values with clear magmatic signature (R/Ra around 7) that is remarkably close to the helium isotope values from the fumaroles (R/Ra= 7.30).

    The Tiris geothermal field (TGF) is indicated by the presence of two sets of surface warm springs located within the proximity of two volcanoes: Mt. Lamongan and Mt. Argopuro. Preliminary assessment of TGF in terms of petrology of the volcanic rock and geochemistry of springs has been studied by Deon et al. (2012). The combination of petrology and geochemistry studies suggests: 1) the relation between sea water and the origin of warm springs and 2) the existence of a concealed layer responsible for capturing H2S gas which, in turn, accounts to the observed HCO3- excess of the springs. In order to support hypotheses resulting from those petrology and geochemistry studies, two passive seismic field experiments have been deployed successively. The first small-scale seismic noise study in 2011 was carried out by setting up 5 geophones for 5-days monitoring positioned around Mt. Lamongan. The second larger-scale passive seismic study has been performed since October 2012 setting up 16 short period stations and 4 broad-band stations around TGF for 6 months monitoring period. The goal of preliminary seismic noise test in 2011 was to identify pre-dominant noise characteristics in the area, while passive seismic monitoring in 2012 attempts to reveal the underground geologic structure of TGF derived from seismic properties. We report the set-up of both experiments and describe first result of seismic noise analysis and preliminary monitoring analysis. References Deon, F.; Moeck, I.; Scheytt, T.; Jaya, M.S.

    The LUSI mud volcano has been erupting since May 2006 in a densely populated district of the Sidoarjo regency (East Java, Indonesia), forcing the evacuation of 40,000 people and destroying industries, farmlands, and 10,000 homes. Peak mud extrusion rates of 180,000 m3/d were measured in the first few months of the eruption, which have decreased to <20,000 m3/d in 2012. Mud volcanoes often release fluids in a pulsating fashion, with periodic timescales ranging from minutes to days, and LUSI is no exception. These oscillations, common in natural systems of multi-phase fluid flow, are thought to result from some combination of complex feedback mechanisms between conduit and source geometry, fluid compressibility, viscosity and density, changes in lithostatic stresses, reservoir pressure, fluid phases or vent conditions. Crisis management workers and local residents reported observations of pulsating eruptive cycles lasting a few hours during the first two years of the eruption, and possibly beyond. Since that time, activity has shifted to individual transient eruptions recurring at intervals of a few minutes. In May and October of 2011, we documented the periodic explosive release of fluids at LUSI using a combination of high-resolution time-lapse photography, continuous webcam, open path FTIR, and thermal infrared imagery. The mud, consisting of approximately 70% water, is erupted at temperatures close to boiling. Gases are periodically released by the bursting of bubbles approximately 3 m in diameter, triggering mud fountains ~20 m in height. No appreciable gas seepage was detected in the quiescent intervals between bubble bursts. Absorption spectrometry in the infrared spectrum reveals that the gas released during explosions consists of 98.5% water vapor, 1% carbon dioxide, and 0.3% methane. On rare occasions, minor amounts of ammonia were also detected. Using simplified plume geometries based on observations, we estimate that LUSI releases approximately 1,500 T

    The El Niño-Southern oscillation and associated changes in the Walker Circulation are major controls on variability in precipitation and convection across the tropical Pacific Ocean. Despite the importance of these phenomena to Pacific, as well as global rainfall, there is considerable debate over whether radiative heating of the tropical Pacific Ocean enhances or reduces Walker Circulation strength and ENSO variability. Paleolimnological reconstructions from Peru (Moy et al., 2002, Nature) and the Galapagos (Conroy et al., 2008, Quat. Sci. Rev.) suggest large variations in precipitation and surface runoff driven by El Niño events during the past millennium at one of ENSO's centers of action in the eastern Pacific. However, these records are rectified signals in that they unable to record ENSO's other phase, La Niña, which results in anomalously high rainfall in the Indo-Pacific Warm Pool region. To gain new perspective on the history of rainfall on the western end of the Walker Circulation over the last 1,200 years, we present a new record of runoff from the southwestern edge of the Indo-Pacific Warm Pool. Our runoff record is constructed with grain size and magnetic susceptibility data from a sediment core from Lake Lading, located in East Java, Indonesia. This core consists of laminated sediments accumulating at 0.45 cm/yr, allowing us to reconstruct surface runoff at 2.2 yr resolution. Runoff events preserved in the well-dated core-top sediments correspond to high monthly rainfall anomalies in instrumental data, and all runoff events between 1950 and 2010 occur during La Niña years. Our data suggests highly variable surface runoff over the past millennium at the multi-decadal timescale, but indicates relatively weak variability at the multi-centennial band, i.e. the well-known Medieval Climate Anomaly (MCA) and Little Ice Age (LIA). During the Medieval Climate Anomaly, when the Asian Summer Monsoon was strong, variations in surface runoff appear to be

    This article identifies the effects of the 1997-98 East Asian economic crisis on health care use and health status in Indonesia. The article places the findings in the context of a framework showing the complex cause and effect relationships underlying the effects of economic downturns on health and health care. The results are based on primary analysis of Indonesian household survey data and review of a wide range of sources from the Indonesian government and international organizations. Comparisons are drawn with the effects of the crisis in Thailand. The devaluation of the Indonesian currency, the Rupiah, led to inflation and reduced real public expenditures on health. Households' expenditures on health also decreased, both in absolute terms and as a percentage of overall spending. Self-reported morbidity increased sharply from 1997 to 1998 in both rural and urban areas of Indonesia. The crisis led to a substantial reduction in health service utilization during the same time period, as the proportion of household survey respondents reporting an illness or injury that sought care from a modern health care provider declined by 25%. In contrast to Indonesia, health care utilization in Thailand actually increased during the crisis, corresponding to expansion in health insurance coverage. The results suggest that social protection programmes play a critical role in protecting populations against the adverse effects of economic downturns on health and health care.

    Subduction-zone volcanism produces a large variety of compositions and eruption styles, but silica-rich explosive eruptions from arc volcanoes are those that pose the most direct threat for those living on and around the volcanoes. The little known Gede volcano (East-Java, Indonesia) is a composite arc-volcano showing evidences of recurrent silicic explosive eruptions and it is a hazard to its 1 million residences settled on its flank also to the two most populated neighboring metropolises: Jakarta and Bandung. Here we present the results of a detailed petrological and geochemical study of Gede's deposits to untangle its magmatic evolution, the key magma reservoir processes, and try to use this information to better anticipate possible future eruptions at Gede. After field-work and dating of the main deposits we identified 5 pyroclastic units ranging from basaltic andesite to dacite, and of eruption ages from about 1 ky to > 45 ky. Bulk-rock major and trace element compositions can be explained as a combination of fractional crystallization and magma mixing/mingling. Crystallization trends evolve with time from wet (amphibole present and plagioclase delayed) to 'dry' (olivine and two pyroxenes, and plagioclase). Petrological and geochemical evidence for within-trend mixing/mingling are common and involve high-Si basalt and dacite end-members. Core to rim electron microprobe and LA-ICP-MS trace element analysis of main phenocrysts (amphibole, plagioclase, ortho- and clinopyroxene) record the details of repetitive magma mixing and mingling events. Cores of amphibole, ortho- and clinopyroxene in the Holocene units have low Mg/Fe, high REEs and Eu-anomaly, and are rimmed Mg/Fe, low REEs and no Eu-anomaly zones. These minerals are thus recording the intrusions of mafic, water-richer and crystal-poor magma into an evolved and partly crystallized magma reservoir. Modeling the diffusive re-equilibration between the crystal cores and rims provides the time elapsed since the

    The spectacular Lusi eruption started in northeast Java, Indonesia the 29 of May 2006 following a M6.3 earthquake striking the island. Initially, several gas and mud eruption sites appeared along the reactivated strike-slip Watukosek fault system and within weeks several villages were submerged by boiling mud. The most prominent eruption site was named Lusi. Lusi is located few kilometres to the NE of the Arjuno-Welirang volcanic complex. Lusi sits upon the Watukosek fault system. From this volcanic complex originates the Watukosek fault system that was reactivated by the M6.3 earthquake in 2006 and is still periodically reactivated by the frequent seismicity. To date Lusi is still active and erupting gas, water, mud and clasts. Gas and water data show that the Lusi plumbing system is connected with the neighbouring Arjuno-Welirang volcanic complex. This makes the Lusi eruption a "sedimentary hosted geothermal system". To verify and characterise the occurrence of seismic activity and how this perturbs the connected Watukosek fault, the Arjuno-Welirang volcanic system and the ongoing Lusi eruption, we deployed 30 seismic stations (short-period and broadband) in this region of the East Java basin. The seismic stations are more densely distributed around LUSI and the Watukosek fault zone that stretches between Lusi and the Arjuno Welirang (AW) complex. Fewer stations are positioned around the volcanic arc. Our study sheds light on the seismic activity along the Watukosek fault system and describes the waveforms associated to the geysering activity of Lusi. The initial network aims to locate small event that may not be captured by the Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG) seismic network and it will be crucial to design the second phase of the seismic experiment that will consist of a local earthquake tomography of the Lusi-Arjuno Welirang region and temporal variations of vp/vs ratios. Such variations will then be ideally related to

    We examined gonococci isolated in 2004, in East Java and Papua, Indonesia, to review the suitability of ciprofloxacin-based and other treatment regimens. Gonococci from the two provinces were tested in Sydney for susceptibility to penicillin, tetracycline, spectinomycin, ceftriaxone, ciprofloxacin, gentamicin, azithromycin and rifampicin. Of 163 gonococcal isolates from East Java (91) and Papua (72), 120 (74%) of gonococci, 62 (68%) and 58 (80%) from East Java and Papua, respectively, were penicillinase-producing gonococci and 162 displayed high-level tetracycline resistance. Eighty-seven isolates (53%) were ciprofloxacin resistant, 44 (48%) from East Java and 43 (60%) from Papua. All isolates were sensitive to cefixime/ceftriaxone, spectinomycin and azithromycin. Minimum inhibitory concentrations of gentamicin were in the range 0.05-8 mg/L. Sixty-nine gonococci (42%) showed combined resistance, to penicillin, tetracycline and quinolones. Quinolone resistance has now reached unacceptable levels, and their use for the treatment of gonorrhoea in Indonesia should be reconsidered.

    Sidoarjo, East Java, Indonesia is the site of LUSI, a terrestrial mud volcano that has been erupting since May 29, 2006. In response to a U.S. Department of State request, the U.S. Geological Survey has been assisting the Indonesian Government to describe the geological and geochemical aspects and potential health risk of the mud eruption. We report here on the organic chemical composition of the mud. Organic chemical analyses were carried out by gas chromatography/mass spectroscopy following organic extraction by microwave-assisted solvent extraction and compound fractionation by adsorption chromatography. There is a petroliferous component in the mud that is fresh, immature, and nonbiodegraded. There is a complete suite of n-alkanes with a bell-shaped pattern typical of fresh petroleum with a Cmax around C20. The alkane content ranges from 0.12 to 1.01 mg/kg dry mud. The presence of certain hopanes (i.e. 17 α,21β(H)-30-norhopane and 17α,21β(H)-hopane) is also indicative of the presence of oil. The proportions of other biomarker compounds (pristane/phytane = 2.4) and the dominance of the C27 sterane (5α(H),14α(H),17α(H)-chlolestane) suggest that oil formed under oxic conditions and has a likely coastal marine or terrigenous source. The presence of oleanane indicates a Cretaceous or younger age for the petrogenic material. These geochemical parameters are consistent with Indonesian oil derived from Tertiary marlstone source rocks that contained kerogen deposited under oxic conditions, probably the upper Miocene Klasafet Formation. Polycyclic aromatic hydrocarbons (PAHs) are present and range in content from 0.1 to 2.2 mg/kg dry mud. The low molecular weight (LMW) PAHs, in particular, naphthalene and methyl-naphthalene are dominant except for perylene which is ubiquitous in the environment. The presence of both parent and higher homologue PAHs indicate a petrogenic rather than combustion source. PAHs are known carcinogens but toxicity data in sediments are

    In 1982, the Far East region was one of the brighter parts of the world for the petroleum industry. Exploratory acreage acquisition, drilling, and seismic activity maintained the busy pace set in 1981. Most parts of the Far East region showed significant and even increased activity compared with 1981. Although drilling was active in 1982, there were no nationally important oil or gas discoveries in the region. Indonesia, Philippines, Malaysia, and India all recorded multiple discoveries, but these for the most part followed the pattern of previous years. Indonesia was the most active country outside of China. A record number of exploratory and delineation wells was drilled in 1982. As in previous years, a plethora of oil and gas discoveries was recorded, but only 1 discovery, a gas discovery in onshore east Kalimantan, is possibly of major significance. Countries which had disappointing exploration programs in 1982 are Bangladesh, Burma, Japan, Philippines, and Taiwan. Exploration in these countries did little to enhance their resource bases. Production in the Far East declined slightly in 1982 to approximately 4.3 million BOPD from 4.4 million BOPD in 1981. This appears to have been mainly due to market conditions. Curtailment of production in Indonesia as a result of the worldwide oil glut offset healthy production gains in India, Malaysia, Philippines, and Thailand. The general attitude of the petroleum industry toward the region was enthusiasm for exploration prospects. Acreage acquisition was brisk in Indonesia, Malyasia, and Thailand. Drilling was on the increase in India, Indonesia, and Thailand. Seismic activity continued strong in most parts of the reporting area. Exploration appears to be alive and well in the Far East.

    This paper describes the progress made in developing geothermal resources at Ulumbu Flores, Indonesia for utilization mini geothermal power generation. Two deep exploratory wells drilling drilled by PLN confirmed the existence of the resources. The well measurement carried out during drilling and after completion of the well indicated that the major permeable zone at around 680 m depth and that this zone is a steam cap zone, which is likely to produce high enthalpy steam. The above information indicates that well ULB-01 will produce a mass flow at least 40 tonnes per hour, which will ensure a 3 MW (E) Ulumbu mini geothermal power plant.

    Peatlands cover around 13 Mha in Sumatra and Kalimantan, Indonesia. Human activities have rapidly increased in the peatland ecosystems during the last two decades, invariably degrading them and making them vulnerable to fires. This causes high carbon emissions that contribute to global climate change. For this article, we used 94 high resolution (10-20 m) satellite images to map the status of peatland degradation and development in Sumatra and Kalimantan using visual image interpretation. The results reveal that less than 4% of the peatland areas remain covered by pristine peatswamp forests (PSFs), while 37% are covered by PSFs with varying degree of degradation. Furthermore, over 20% is considered to be unmanaged degraded landscape, occupied by ferns, shrubs and secondary growth. This alarming extent of degradation makes peatlands vulnerable to accelerated peat decomposition and catastrophic fire episodes that will have global consequences. With on-going degradation and development the existence of the entire tropical peatland ecosystem in this region is in great danger. PMID:21053723

    The 29th of May 2006 numerous eruption sites started in northeast Java, Indonesia following to a M6.3 earthquake striking the island.Within a few weeks an area or nearly 2 km2 was covered by boiling mud and rock fragments and a prominent central crater (named Lusi) has been erupting for the last 9.5 years. The M.6.3 seismic event also triggered the activation of the Watukosek strike slip fault system that originates from the Arjuno-Welirang volcanic complex and extends to the northeast of Java hosting Lusi and other mud volcanoes. Since 2006 this fault system has been reactivated in numerous instances mostly following to regional seismic and volcanic activity. However the mechanism controlling this activity have never been investigated and remain poorly understood. In order to investigate the relationship existing between seismicity, volcanism, faulting and Lusi activity, we have deployed a network of 31 seismometers in the framework of the ERC-Lusi Lab project. This network covers a large region that monitors the Lusi activity, the Watukosek fault system and the neighboring Arjuno-Welirang volcanic complex. In particular, to understand the consistent pattern of the source mechanism, relative to the general tectonic stress in the study area, a detailed analysis has been carried out by performing the moment tensor inversion for the near field data collected from the network stations. Furthermore these data have been combined with the near field data from the regional network of the Meteorological, Climatological and Geophysical Agency of Indonesia that covers the whole country on a broader scale.

    Classical swine fever virus (CSFV) is a highly infectious disease of pigs. It has had significant impacts on East Nusa Tenggara, eastern Indonesia since its introduction in 1997. In spite of its importance to this region, little is known about its seroprevalence and distribution, and pig-level and farmer-level factors that may have an impact on the serological status of an individual pig. To address this knowledge deficit, a cross-sectional seroprevalence survey was conducted in 2010 involving 2160 pigs and 805 farmers from four islands in the region. Farmer questionnaires and pig record forms were used to collect data about the farmers and pigs surveyed. Blood was collected from each pig to determine its CSFV serological status. Apparent and true prevalence were calculated for each island, district, subdistrict, and village surveyed. CSFV serological status was used as an outcome variable in mixed effects logistic regression analyses. Overall true CSFV seroprevalence was estimated at 17.5% (lower CI 16.0%; upper CI 19.5%). Seroprevalence estimates varied widely across the islands, districts, subdistricts, and villages. Manggarai Barat, a district on the western end of Flores Island, contained pigs that were positive for antibody to CSFV. This result was unexpected, as no clinical cases had been reported in this area. Older pigs and pigs that had been vaccinated for CSFV were more likely to test positive for antibody to CSFV. The final multivariable model accounted for a large amount of variation in the data, however much of this variation was explained by the random effects with less than 2% of the variation explained by pig age and pig CSFV vaccination status. In this study we documented the seroprevalence of CSFV across four islands in East Nusa Tenggara, eastern Indonesia. We also identified risk factors for the presence of antibody to CSFV. Further investigation is needed to understand why clinical CSFV has not been reported on the western end of Flores Island

    On May 29, 2006, mud and gases began erupting unexpectedly from a vent 150 meters away from a hydrocarbon exploration well near Sidoarjo, East Java, Indonesia. The eruption, called the LUSI (Lumpur 'mud'-Sidoarjo) mud volcano, has continued since then at rates as high as 160,000 m3 per day. At the request of the United States Department of State, the U.S. Geological Survey (USGS) has been providing technical assistance to the Indonesian Government on the geological and geochemical aspects of the mud eruption. This report presents initial characterization results of a sample of the mud collected on September 22, 2007, as well as inerpretive findings based on the analytical results. The focus is on characteristics of the mud sample (including the solid and water components of the mud) that may be of potential environmental or human health concern. Characteristics that provide insights into the possible origins of the mud and its contained solids and waters have also been evaluated.

    It is important to decipher tropical climate history over the last millennium bercause the tropics is a critical region to drive the global climate system. Although geochemical records in stalagmites have been widely recognized as a powerful tool for the elucidation of paleoclimate/environment of the terrestrial areas, the previous data are mainly reported from areas that are located in middle latitude. Accordingly, this study aims at reconstructing past climate variations in the Asian equatorial regions by using oxygen and carbon isotope ratios recorded in Indonesian stalagmites. In this study, we performed a systematic comparison between temporal variation in precipitation and those in δ18O and δ13C of two stalagmites from western and eastern Java, Indonesia in order to assess the reliability of stable isotopic ratios of stalagmites as climate proxies. We measured annual variations of stable isotpic data and compared with that of rainfall amounts, showing significant, negative correlations. These correlations suggest that stable isoptopic ratios of stalagmites are a useful proxy for reconstructing anient precipitaions in this study areas. Furthermore, we reconstructed rainfall variation over the 500 years (1440-2006 AD), based on stable isotopic data recorded in the stalagmite of western Java. δ18O and δ13C vary from -7.7 permil to -5.4 permil and from -14.1 permil to -11 permil, respectively.

    We report new helium isotope analyses of olivine and clinopyroxene separates from recent lavas for eleven volcanoes from Flores in the east Sunda arc through the inactive segment between the arcs to Banda Island at the extreme of the contiguous Banda arc. In the east Sunda arc, 3He /4He ratios ( R) vary between 4.5 RA ( R A = air 3He /4He ) for the leucitic Batu Tara volcano to a remarkable low of pure radiogenic helium (0.0075 RA) for Werung at the southern tip of Lomblen Island. Lavas from the inactive zone, which represents the locus of collision of the Australian continent with the arc, have a narrower range in R/R A - from 3.9 for Kisu in the straits of Pantar to 1.0 for Romang Island. Our one locality (Banda Island) in the Banda arc gives the highest R/R A ratio (3.1) observed along this arc to date. The results are consistent with the involvement of crustal material in magma genesis throughout the east Sunda/Banda arcs, as far west as Iya in central Flores. We combine these helium isotope results with published and on-going strontium isotope studies, and show that the source of the helium in the crustal component is unlikely to be terrigenous sediments derived from the Australian continent; rather, degassing of Australian continental crust appears to be the dominant process controlling the helium budget. The He-Sr isotope systematics also provide a framework to account for the areal pattern of 3He /4He in this part of the arcs: the radiogenic crustal component is diluted with mantle helium both in a down-dip direction and with increasing lateral distance from the collision zone. These factors result in an excellent first-order relationship between the 3He /4He ratio, degree of He/Sr enrichment (relative to the postulated mantle endmember), and alkalinity of the erupted lavas. Such a relationship has a direct bearing on models of the tectonic evolution of the collision zone, and on the observation that helium isotopes are decoupled from strontium and other

    The crater lake of Kawah Ijen volcano, East Java, Indonesia, has displayed large and rapid changes in temperature at point locations during periods of unrest, but measurement techniques employed to date have not resolved how the lake's thermal regime has evolved over both space and time. We applied a novel approach for mapping and monitoring variations in crater lake apparent surface ("skin") temperatures at high spatial (˜32 cm) and temporal (every 2 min) resolution at Kawah Ijen on 18 September 2014. We used a ground-based FLIR T650sc camera with digital and thermal infrared (TIR) sensors from the crater rim to collect (1) a set of visible imagery around the crater during the daytime and (2) a time series of co-located visible and TIR imagery at one location from pre-dawn to daytime. We processed daytime visible imagery with the Structure-from-Motion photogrammetric method to create a digital elevation model onto which the time series of TIR imagery was orthorectified and georeferenced. Lake apparent skin temperatures typically ranged from ˜21 to 33 °C. At two locations, apparent skin temperatures were ˜4 and 7 °C less than in situ lake temperature measurements at 1.5 and 5-m depth, respectively. These differences, as well as the large spatio-temporal variations observed in skin temperatures, were likely largely associated with atmospheric effects such as the evaporative cooling of the lake surface and infrared absorption by water vapor and SO2. Calculations based on orthorectified TIR imagery thus yielded underestimates of volcanic heat fluxes into the lake, whereas volcanic heat fluxes estimated based on in situ temperature measurements (68 to 111 MW) were likely more representative of Kawah Ijen in a quiescent state. The ground-based imaging technique should provide a valuable tool to continuously monitor crater lake temperatures and contribute insight into the spatio-temporal evolution of these temperatures associated with volcanic activity.

    We focus in this paper on the processes and consequences of an unusual volcanic eruption at Kelut volcano, East Java. In November 2007, after two months of worrying precursor signs, Kelut volcano erupted. But neither explosions nor the usual hazards observed during the historic eruptions happened (e.g. ash falls, volcanic bombs and pyroclastic flows). Instead of an explosive eruption, the 2007 eruption was extrusive. Given than such an eruption could not be predicted, the authorities had to manage a new situation. We conducted interviews with nine stakeholders of the crisis management team, and undertook a questionnaire-based survey in the settlement nearest to the crater, in order to understand how the authorities managed the crisis, and how people reacted. Inquiries and questionnaires were carried out shortly after the end of the evacuation process, when the volcano was still under surveillance for fear of an explosive phase. The results display a real gap in what it takes to manage a crisis or live through a crisis. This suggests that the "unusual" eruption pattern of Kelut volcano was not the only factor of the misunderstanding between the authorities and the population. These problems stem from more structural causes such as the lack of communication and information when there is a need to adapt to a new scenario. In such a situation, the inability of the crisis management system to take decisions underscored the intrinsic vulnerability of the population despite a hierarchical and strategic top-down crisis management approach.

  3. Diplomacy Through Earth Sciences: An Overview of US Geological Survey Technical Assistance Regarding the Ongoing LUSI Mud Eruption, East Java, Indonesia

    In June 2007, the US Department of State (DOS) requested assistance from the USGS to provide technical guidance and advice to the US Mission in Indonesia regarding the Lumpur Sidoarjo (LUSI) mud crisis. In May 2006, LUSI began as a mud eruption from a series of mud springs adjacent to an oil and gas exploration well being drilled near Surabaya, East Java, Indonesia. The production of mud and waters from the LUSI crater area has now continued for more than 3 years with no significant change in mud production rate (~110,000 cubic meters per day) nor in temperature of the mud (70-80 degrees C). Engineers suggest that mud production will continue at these rates for years to decades to come. Regardless of future activity at LUSI, the current mud accumulation of more than 100 million cubic meters poses a physical and environmental hazard which requires continuous monitoring and observation. The first response to the 2007 DOS request involved a site visit to Indonesia in September 2007. The result of that visit was to recommend to the Government of Indonesia (GOI) that they focus on long-term management of the mud rather than focus on the controversy as to the cause of the eruption or the debate about stopping the flow. Other recommendations from the initial 2007 technical visit included contracting for a US scientist to be co-located with engineers of the Sidoarjo Mud Management Board (BPLS) in Surabaya, East Java, to advise and consult on day-to-day developments at the site of the mud eruption. A second technical team visit by USGS scientists and an engineer from the US Army Corps of Engineers in October-November 2008 made additional recommendations on the long-term management of the mud and was followed in December by the start of a 6 month contract for the US mud adviser. From the start of activity in mid-2006 through late-2008, there was a clear sense of urgency at the US Mission in Indonesia to provide guidance and advice and included the personal intervention of

    In the course of searching for new materials to use as whitening agents, we screened 19 methanol extracts prepared from 14 medicinal plants from Central Kalimantan province, Indonesia. The screening methods used were the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging assay, a tyrosinase inhibition assay, and a melanin formation inhibition assay using B16 melanoma cells. The extracts of Willughbeia coriacea (bark part of aerial root), Phyllanthus urinaria (root), Eleutherine palmifolia (bulb), Eusideroxylon zwageri (seed), Dendrophthoe petandra (aerial root), Passiflora foetida (stem), and Vitex pinnata (root) showed DPPH radical-scavenging activity of more than 70% at 100 microg/ml. The extracts of W. coriacea (bark part of aerial root), P. urinaria (root), and D. petandra (aerial root) showed tyrosinase inhibitory activity of more than 40% using L-tyrosine as a substrate at 500 microg/ml. The extracts of W. coriacea (bark part of aerial root) and D. petandra (aerial root) showed tyrosinase inhibitory activity of more than 40% using L-DOPA as a substrate at 500 microg/ml. The extracts of W. coriacea (bark part of aerial root, 200 microg/ml), Glochidion philippcum (aerial root, 200 and 300 microg/ml), E. palmifolia (bulb, 50 microg/ml), E. zwageri (seed, 100 microg/ml), D. petandra (aerial root, 200 microg/ml), Lansium domesticum (bark, 25 microg/ml), P. foetida (stem, fruit, 300 microg/ml), and Solanum torvum (root, 300 microg/ml) strongly inhibited the melanin production of B16 melanoma cells without significant cytotoxicity. These findings indicate that some medicinal plants from Central Kalimantan are potential ingredients for skin-whitening cosmetics if their safety can be confirmed. PMID:19618251

    To expand the documentation of rickettsioses in Indonesia, we conducted an ectoparasite and small mammal investigation involving four major islands: Java, Sumatra, Sulawesi, and Kalimantan. Coastal and highland regions on each island surveyed were chosen to represent different ecologies in Indonesia. Indication of the presence of Rickettsia spp. was evident in all areas sampled. Typhus group rickettsiae-specific antibodies had significantly higher prevalence among small mammals captured in Java compared to the other islands surveyed (78% in coastal and 50% in highland regions) and the prevalence of spotted fever group rickettsiae-specific antibodies was significantly higher in Kalimantan than the other islands investigated. Hosts and vectors were restricted by Rickettsia spp. but not by coastal or highland regions. Our findings expand the range in which rickettsial pathogens have been documented within the Indonesian archipelago and point to a significant risk to human health.

    The crater lake of Kawah Ijen volcano, East Java, Indonesia, has displayed large and rapid changes in temperature at point locations during periods of unrest, but measurement techniques employed to-date have not resolved how the lake’s thermal regime has evolved over both space and time. We applied a novel approach for mapping and monitoring variations in crater-lake apparent surface (“skin”) temperatures at high spatial (~32 cm) and temporal (every two minutes) resolution at Kawah Ijen on 18 September 2014. We used a ground-based FLIR T650sc camera with digital and thermal infrared (TIR) sensors from the crater rim to collect (1) a set of visible imagery around the crater during the daytime and (2) a time series of co-located visible and TIR imagery at one location from pre-dawn to daytime. We processed daytime visible imagery with the Structure-from-Motion photogrammetric method to create a digital elevation model onto which the time series of TIR imagery was orthorectified and georeferenced. Lake apparent skin temperatures typically ranged from ~21 to 33oC. At two locations, apparent skin temperatures were ~ 4 and 7 oC less than in-situ lake temperature measurements at 1.5 and 5 m depth, respectively. These differences, as well as the large spatio-temporal variations observed in skin temperatures, were likely largely associated with atmospheric effects such as evaporative cooling of the lake surface and infrared absorption by water vapor and SO2. Calculations based on orthorectified TIR imagery thus yielded underestimates of volcanic heat fluxes into the lake, whereas volcanic heat fluxes estimated based on in-situ temperature measurements (68 to 111 MW) were likely more representative of Kawah Ijen in a quiescent state. The ground-based imaging technique should provide a valuable tool to continuously monitor crater-lake temperatures and contribute insight into the spatio-temporal evolution of these temperatures associated with volcanic activity.

    Instrumental and historical records of earthquakes, supplemented by paleoeseismic constraints can help reveal the earthquake potential of an area. The Pasuruan fault is a high angle normal fault with prominent youthful scarps cutting young deltaic sediments in the north coast of East Java, Indonesia and may pose significant hazard to the densely populated region. This fault has not been considered a significant structure, and mapped as a lineament with no sense of motion. Information regarding past earthquakes along this fault is not available. The fault is well defined both in the imagery and in the field as a ~13km long, 2-50m-high scarp. Open and filled fractures and natural exposures of the south-dipping fault plane indicate normal sense of motion. We excavated two fault-perpendicular trenches across a relay ramp identified during our surface mapping. Evidence for past earthquakes (documented in both trenches) includes upward fault termination with associated fissure fills, colluvial wedges and scarp-derived debris, folding, and angular unconformities. The ages of the events are constrained by 23 radiocarbon dates on detrital charcoal. We calibrated the dates using IntCal13 and used Oxcal to build the age model of the events. Our preliminary age model indicates that since 2006±134 B.C., there has been at least five ground rupturing earthquakes along the fault. The oldest event identified in the trench however, is not well-dated. Our modeled 95th percentile ranges of the next four earlier earthquakes (and their mean) are A.D. 1762-1850 (1806), A.D. 1646-1770 (1708), A.D. 1078-1648 (1363), and A.D. 726-1092 (909), yielding a rough recurrence rate of 302±63 yrs. These new data imply that Pasuruan fault is more active than previously thought. Additional well-dated earthquakes are necessary to build a solid earthquake recurrence model. Rupture along the whole section implies a minimum earthquake magnitude of 6.3, considering 13km as the minimum surface rupture

    The existence of multiple independently derived populations in landlocked marine lakes provides an opportunity for fundamental research into the role of isolation in population divergence and speciation in marine taxa. Marine lakes are landlocked water bodies that maintain a marine character through narrow submarine connections to the sea and could be regarded as the marine equivalents of terrestrial islands. The sponge Suberites diversicolor (Porifera: Demospongiae: Suberitidae) is typical of marine lake habitats in the Indo-Australian Archipelago. Four molecular markers (two mitochondrial and two nuclear) were employed to study genetic structure of populations within and between marine lakes in Indonesia and three coastal locations in Indonesia, Singapore and Australia. Within populations of S. diversicolor two strongly divergent lineages (A & B) (COI: p = 0.4% and ITS: p = 7.3%) were found, that may constitute cryptic species. Lineage A only occurred in Kakaban lake (East Kalimantan), while lineage B was present in all sampled populations. Within lineage B, we found low levels of genetic diversity in lakes, though there was spatial genetic population structuring. The Australian population is genetically differentiated from the Indonesian populations. Within Indonesia we did not record an East-West barrier, which has frequently been reported for other marine invertebrates. Kakaban lake is the largest and most isolated marine lake in Indonesia and contains the highest genetic diversity with genetic variants not observed elsewhere. Kakaban lake may be an area where multiple putative refugia populations have come into secondary contact, resulting in high levels of genetic diversity and a high number of endemic species.

    Indonesia is subject to rapid land use change. One of the main causes for the conversion of land is the rapid expansion of the oil palm sector. Land use change involves a progressive loss of forest cover, with major impacts on biodiversity and global CO2 emissions. Ecosystem services have been proposed as a concept that would facilitate the identification of sustainable land management options, however, the scale of land conversion and its spatial diversity pose particular challenges in Indonesia. The objective of this paper is to analyze how ecosystem services can be mapped at the provincial scale, focusing on Central Kalimantan, and to examine how ecosystem services maps can be used for a land use planning. Central Kalimantan is subject to rapid deforestation including the loss of peatland forests and the provincial still lacks a comprehensive land use plan. We examine how seven key ecosystem services can be mapped and modeled at the provincial scale, using a variety of models, and how large scale ecosystem services maps can support the identification of options for sustainable expansion of palm oil production.

Indonesia has made substantial progress in domestic disaster management with the establishment of central administrative authority, strategic planning, and training programs. Nevertheless, the Indonesian experience reveals recurrent issues in international humanitarian health assistance. Clinical care remains complicated by absences of treatment protocols, inappropriate drug use, high procedural complication rates, and variable referral practices. Epidemiological surveillance remains complicated by unsettled clinical case definitions, non-standardized case management of diseases with epidemic potential, variable outbreak management protocols, and inadequate epidemiological analytic capacity.

    The 1997 El Niño unfolded as one of the most sever El Niño Southern Oscillation (ENSO) events in this century and it coincided with massive biomass burning in the equatorial western Pacific region. To assess the influence on the atmosphere, aircraft observations of trace gases and aerosol were conducted over Kalimantan in Indonesia and Australia. Over Kalimantan in Indonesia, high concentrations of O3, NOx, CO, and aerosols were observed during the flight. Although the aerosol and NOx decreased with altitude, the O3 had the maximum concentration (80.5 ppbv) in the middle layer of the smoke haze and recorded very low concentrations (˜20 ppbv) in the lower smoke layer. This feature was not observed in the Australian smoke. We proposed several hypotheses for the low O3 concentration at low levels over Kalimantan. The most likely are lack of solar radiation and losses at the surface of aerosol particles.

    Beginning a few thousand years ago, global climate and environmental change have become more and more affected by human activities. Hence, quantifying the 'human component' becomes increasingly important in order to predict future developments. Indonesia and the surrounding oceans are key in this respect, because it is in the region (i) that receives the highest inputs of water, sediment and associated dissolved and particulate substances and (ii) that suffers from anthropogenically modified landscapes and coastal zones. As opposing the global trend, land-based human activities have increased the sediment input into the ocean from Indonesia since pre-human times. Nevertheless, there are strong gradients in land use/cover and resulting river fluxes within Indonesia as, for example, between Java and Kalimantan. Major goal of this study is to identify the contribution of human activities in river catchments (i.e. land use/cover change, hydrological alterations) to gradients in carbon and nitrogen deposition in sediments of the Java Sea between densely populated Java and sparsely populated Kalimantan during the Late Holocene. We hypothesized that the riverine input of C and N increased during the late Holocene and increased more off Java than off Kalimantan. Sediment cores (80 to 130 cm long) off major river mouths from Java (2 cores off Bengawan Solo) and Kalimantan (1 core off Pembuang, 1 core off Jelai) were dated and analysed for Corg, Ntot, carbonate and stable isotope composition (δ13Corg, δ15N) in 3 cm intervals. Sedimentation rates off the Kalimantan rivers with 0.05-0.11 cm yr-1 were higher than off the Bengawan Solo, the largest river catchment on Java (<0.04 cm yr-1). Ntot contents in all sediment cores were low with ~0.07% and varied little over time. A higher Corg content, molar C/N ratio and variability over the past 5000 years in all parameters in the core closer to the river mouth off the Bengawan Solo than the one further offshore indicates that

    A fossil femur excavated by Eugène Dubois between 1891–1900 in the Lower/Middle Pleistocene bonebed of the Trinil site (Java, Indonesia) was recognised by us as that of a Hylobatidae. The specimen, Trinil 5703 of the Dubois Collection (Leiden, The Netherlands), has the same distinctive form of fossilization that is seen in many of the bonebed fossils from Trinil in the collection. Anatomical comparison of Trinil 5703 to a sample of carnivore and primate femora, supported by morphometric analyses, lead to the attribution of the fossil to gibbon. Trinil 5703 therefore provides the oldest insular record of this clade, one of the oldest known Hylobatidae fossils from Southeast Asia. Because living Hylobatidae only inhabit evergreen rain forests, the paleoenvironment within the river drainage in the greater Trinil area evidently included forests of this kind during the Lower/Middle Pleistocene as revealed here.

Trinil 5703 therefore provides the oldest insular record of this clade, one of the oldest known Hylobatidae fossils from Southeast Asia. Because living Hylobatidae only inhabit evergreen rain forests, the paleoenvironment within the river drainage in the greater Trinil area evidently included forests of this kind during the Lower/Middle Pleistocene as revealed here.

    We quantitatively analyze the area-age distribution of sedimentary, igneous and metamorphic bedrock based on data from the most recent digital geologic maps of East and Southeast Asia (Coordinating Committee for Coastal and Offshore Geosciences Programmes in East and Southeast Asia (CCOP) and the Geologic Survey of Japan, 1997; 1:2,000,000), published as Digital Geoscience Map G-2 by the Geological Survey of Japan. Sedimentary rocks, volcanic rocks, plutonic rocks, ultramafic rocks and metamorphic rocks cover 73.3%, 8.5%, 8.8%, 0.9%, and 8.6% of the surface area, respectively. The average ages of major lithologic units, weighted according to bedrock area, are as follows: sedimentary rocks (average stratigraphic age of 123 Myr/median age of 26 Myr), volcanic rocks (84 Myr/20 Myr), intrusive rocks (278 Myr/195 Myr), ultramafic rocks (unknown) and metamorphic rocks (1465 Myr/1118 Myr). The variability in lithologic composition and age structure of individual countries reflects the complex tectonic makeup of this region that ranges from Precambrian cratons (e.g., northeast China and North Korea) to Mesozoic-Cenozoic active margins (e.g., Japan, the Philippines, Indonesia and New Guinea). The spatial resolution of the data varies from 44 km2 per polygon (Japan) to 1659 km2 per polygon (Taiwan) and is, on average (490 km2/polygon), similar to our previous analyses of the United States of America and Canada. The temporal and spatial resolution is sufficiently high to perform age-area analyses of individual river basins larger than ˜10,000 km2 and to quantitatively evaluate the relationship between bedrock geology and river chemistry. As many rivers draining tropical, mountainous islands of East and Southeast Asia have a disproportionate effect on the dissolved and particulate load delivered to the world oceans, bedrock geology in such river drainage basins disproportionately affect ocean chemistry.

  3. Application of synthetic aperture radar (SAR) imagery to volcano mapping in the humid tropics: a case study in East Java, Indonesia

    NASA Astrophysics Data System (ADS)

    Carn, Simon A.

    Volcanoes in humid tropical environments are frequently cloud covered, typically densely vegetated and rapidly eroded. These factors complicate field and laboratory studies and even the basic identification of potentially active volcanoes. Numerous previous studies have highlighted the potential value of radar remote sensing for volcanology in equatorial regions. Here, cloud- and vegetation-penetrating LHH-band (λ 24cm) synthetic aperture radar (SAR) data from the Japanese Earth Resources Satellite (JERS-1) are used to investigate persistently active volcanoes and prehistoric calderas in East Java, Indonesia. The LHH-band JERS-1 SAR produces high-spatial-resolution (18m) imagery with relatively high incidence angle that highlights structures and topographic variations at or greater than the wavelength scale while minimising geometrical distortions such as layover and foreshortening. These images, along with Internet browse data derived from the Canadian RADARSAT mission, provide new evidence relating regional tectonics to volcanism throughout East Java. Volcanic events, such as caldera collapse at the Tengger caldera, appear to have been partly controlled by northwest-aligned faults related to intra-arc sedimentary basins. Similar regional controls appear important at historically active Lamongan volcano, which is encircled by numerous flank maars and cinder cones. A previously undocumented pyroclastic sheet and debris avalanche deposit from the Jambangan caldera complex is also manifested in the synoptic radar images. At the currently active Semeru volcano these data permit identification of recent pyroclastic flow and lahar deposits. Radar data therefore offer a valuable tool for mapping and hazard assessment at late Quaternary volcanoes. The criteria developed in the analysis here could be applied to other regions in the humid tropics.

    The Lusi eruption began on May 29, 2006 in the northeast of Java Island, Indonesia, and to date is still active. Lusi is a newborn sedimentary-hosted hydrothermal system characterized by continuous expulsion of liquefied mud and breccias and geysering activity. Lusi is located upon the Watukosek fault system, a left lateral wrench system connecting the volcanic arc and the bakarc basin. This fault system is still periodically reactivated as shown by field data. In the framework of the Lusi Lab project (ERC grant n° 308126) we conducted several types of monitoring. Based on camera observations, we characterized the Lusi erupting activity by four main behaviors occurring cyclically: (1) Regular activity, which consists in the constant emission of water and mud breccias (i.e. viscous mud containing clay, silt, sand and clasts) associated with the constant expulsion of gas (mainly aqueous vapor with minor amounts of CO2 and CH4) (2) Geysering phase with intense bubbling, consisting in reduced vapor emission and more powerful bursting events that do not seem to have a regular pattern. (3) Geysering phase with intense vapor and degassing discharge and a typically dense plume that propagates up to 100 m height. (4) Quiescent phase marking the end of the geysering activity (and the observed cycle) with no gas emissions or bursts observed. To investigate the possible seismic activity beneath Lusi and the mechanisms controlling the Lusi pulsating behaviour, we deployed a network of 5 seismic stations and a HD camera around the Lusi crater. We characterize the observed types of seismic activity as tremor and volcano-tectonic events. Lusi tremor events occur in 5-10 Hz frequency band, while volcano tectonic events are abundant in the high frequencies range from 5 Hz until 25 Hz. We coupled the seismic monitoring with the images collected with the HD camera to study the correlation between the seismic tremor and the different phases of the geysering activity. Key words: Lusi

    Rabies is a major fatal zoonotic disease in Indonesia. This study was conducted to determine the recent dynamics of rabies virus (RABV) in various areas and animal species throughout Indonesia. A total of 27 brain samples collected from rabid animals of various species in Bali, Sumatra, Kalimantan, Sulawesi, Java, and Flores in 2008 to 2010 were investigated. The cDNA of the nucleoprotein gene from each sample was generated and amplified by one-step reverse transcription-PCR, after which the products were sequenced and analyzed. The symmetric substitution model of a Bayesian stochastic search variable selection extension of the discrete phylogeographic model of the social network was applied in BEAST ver. 1.7.5 software. The spatial dispersal was visualized in Cartographica using Spatial Phylogenetic Reconstruction of Evolutionary Dynamics. We demonstrated inter-island introduction and reintroduction, and dog was found to be the only source of infection of other animals. Ancestors of Indonesian RABVs originated in Java and its descendants were transmitted to Kalimantan, then further to Sumatra, Flores, and Bali. The Flores descendent was subsequently transmitted to Sulawesi and back to Kalimantan. The viruses found in various animal species were transmitted by the dog.

    The blue swimming crab Portunus pelagicus is an important catch species for many coastal villages along the Java Sea coastline, but little is known regarding its reproductive biology or stock status. We examined the batch fecundity of female crabs that were collected monthly at landing sites from June 2011 to May 2012, calculated the relationships with body size, egg mass and month of the year, and determined the size at which females became potentially reproductive in the population inhabiting East Lampung waters (western Java Sea). Fecundity values ranged from 229,468 to 2,236,355 (mean = 926,638±30,975 [±SE]). The fecundity was positively and linearly correlated with carapace width (CW), but the relationships with body weight and egg mass were best described by logarithmic regression. A peaked, temporally cyclical pattern in fecundity was observed, with a peak period that was significantly different (F = 226.36; df = 22, p<0.05) from March to May 2012. Reproductive females were within the 111.0–155.9 mm CW size range; significantly higher reproductive potentials (F = 14.59; df = 30, p<0.05) were found in females within the 126.0–130.9 mm CW size group. The current minimum legal size (MLS = 100 mm CW) is not an appropriate limit reference point, and a precautionary approach is needed for a sustainable harvesting strategy. Resetting the MLS to 115 mm CW would potentially provide adequate protection for spawning females and increase total egg production, thereby maintaining population productivity and enhancing resilience in the face of current fishing pressures.

    To evaluate the lateritization process and supergene Ni enrichment in the tropical rainforest, a well developed laterite profile over the serpentinite in the Kolonodale area of East Sulawesi, Indonesia, has been investigated using field geology methods, mineralogical and geochemical techniques. Three lithostratigraphic horizons over the bedrock are distinguished from bottom to top: the saprolite horizon, the limonite horizon, and the ferruginous cap. In general, the profile is characterized by (1) a depth-related pH ranging from 5.56 to 8.56, with a higher value in the saprolite horizon and a lower value in the ferruginous cap, (2) a highly variable organic matter concentration from 1.11% to 4.82%, showing a increasing trend from bottom to top, (3) a progressive mineral assemblage transition from the silicate mineral dominant (mainly serpentine) to the Fe-oxyhydroxide dominant (mainly goethite), and (4) a typical laterite geochemical pattern with an increase of Fe, Al, Mn, Cr and Ti but a decrease of Mg, Ca, Na and K upward from the bedrock. The highest concentration of Ni (up to 11.53%NiO) occurs in the saprolite horizon, showing nearly 40 times richer compared to the bedrock. The mineral evolution during the lateritization process shows various paths from the primary minerals to altered minerals, which is integrally affected by the nature of the primary minerals and environmental conditions. Garnierite, as a significant ore mineral formed by the secondary precipitation processes in the study profile, is identified as a mixture of talc- and serpentine-like phases. The mass-balance calculation reveals that there are diversified elemental behaviors during the serpentinite lateritization under the rainforest conditions. In particular, Ni, as the ore-forming element in the laterite profile, is associated closely with the pH environment, organic matter concentration and mineral evolution during the lateritization process. The findings of the present study support a

    Indonesia has reported the most human infections with highly pathogenic avian influenza (HPAI) A(H5N1) virus worldwide. We implemented enhanced surveillance in four outpatient clinics and six hospitals for HPAI H5N1 and seasonal influenza viruses in East Jakarta district to assess the public health impact of influenza in Indonesia. Epidemiological and clinical data were collected from outpatients with influenza-like illness (ILI) and hospitalized patients with severe acute respiratory infection (SARI); respiratory specimens were obtained for influenza testing by real-time reverse transcription-polymerase chain reaction. During October 2011-September 2012, 1131/3278 specimens from ILI cases (34·5%) and 276/1787 specimens from SARI cases (15·4%) tested positive for seasonal influenza viruses. The prevalence of influenza virus infections was highest during December-May and the proportion testing positive was 76% for ILI and 36% for SARI during their respective weeks of peak activity. No HPAI H5N1 virus infections were identified, including hundreds of ILI and SARI patients with recent poultry exposures, whereas seasonal influenza was an important contributor to acute respiratory disease in East Jakarta. Overall, 668 (47%) of influenza viruses were influenza B, 384 (27%) were A(H1N1)pdm09, and 359 (25%) were H3. While additional data over multiple years are needed, our findings suggest that seasonal influenza prevention efforts, including influenza vaccination, should target the months preceding the rainy season.

    Palm oil is a promising source of cooking oil and biodiesel. The demand for palm oil has been increasing worldwide. However, concerns exist surrounding the environmental and socio-economic sustainability of palm oil production. Indonesia is a major palm oil producing country. We explored scenarios for palm oil production in Indonesia until 2050, focusing on Sumatra, Kalimantan and Papua. Our scenarios describe possible trends in crude palm oil production in Indonesia, while considering the demand for cooking oil and biodiesel, the available land for plantations, production capacity (for crude palm oil and fresh fruit bunches) and environmentally restricting conditions. We first assessed past developments in palm oil production. Next, we analysed scenarios for the future. In the past 20years, 95% of the Indonesian oil palm production area was in Sumatra and Kalimantan and was increasingly cultivated in peatlands. Our scenarios for the future indicate that Indonesia can meet a considerable part of the global and Asian demand for palm oil, while avoiding further cultivation of peatlands and forest. By 2050, 264-447Mt crude palm oil may be needed for cooking oil and biodiesel worldwide. In Indonesia, the area that is potentially suitable for oil palm is 17 to 26Mha with a potential production rate of 27-38t fresh fruit bunches/ha, yielding 130-176Mt crude palm oil. Thus Indonesia can meet 39-60% of the international demand. In our scenarios this would be produced in Sumatra (21-26%), Kalimantan (12-16%), and Papua (2%). The potential areas include the current oil palm plantation in mineral lands, but exclude the current oil palm plantations in peatlands.

    Over millennia, atmospheric carbon dioxide has been sequestered and stored in Indonesia's tropical wetland forests. Waterlogged conditions impede decomposition, allowing the formation of deep organic soils. These globally significant C pools are highly vulnerable to deforestation, degradation and climate change which can potentially switch their function as C sinks to long term sources of greenhouse gas (GHG) emissions. Also at risk are critical ecosystem services which sustain millions of people and the conservation of unique biological communities. The multiple benefits derived from wetland forest conservation makes them attractive for international C offset programs such as the proposed Reduced Emissions from Deforestation and Degradation (REDD+) mechanism. Yet, ecosystem C pools and fluxes in wetland forests remain poorly quantified. Significant knowledge gaps exist regarding how land use changes impact C dynamics in tropical wetlands, and very few studies have simultaneously assessed above- and belowground ecosystem C pools in Indonesia's freshwater peat swamps and mangroves. In addition, most of what is known about Indonesia's tropical wetland forests is derived from few geographic locations where long-standing research has focused, despite their broad spatial distribution. Here we present results from an extensive survey of ecosystem C stocks across several Indonesian wetland forests. Ecosystem C stocks were measured in freshwater peat swamp forests in West Papua, Central Kalimantan, West Kalimantan, and Sumatra. Carbon storage was also measured for mangrove forests in W. Papua, W. Kalimantan, and Sumatra. One overarching goal of this research is to support the development of REDD+ for tropical wetlands by informing technical issues related to carbon measuring, monitoring, and verification (MRV) and providing baseline data about the variation of ecosystem C storage across and within several Indonesian wetland forests.

    Kelut volcano, East Java, is an active volcanic complex hosting a summit crater lake that has been the source of some of Indonesia's most destructive lahars. In November 2007, an effusive eruption lasting approximately 7 months led to the formation of a 260-m-high and 400-m-wide lava dome that displaced most of the crater lake. The 2007-2008 Kelut dome comprises crystal-rich basaltic andesite with a texturally complex crystal cargo of strongly zoned and in part resorbed plagioclase (An47-94), orthopyroxene (En64-72, Fs24-32, Wo2-4), clinopyroxene (En40-48, Fs14-19, Wo34-46), Ti-magnetite (Usp16-34) and trace amounts of apatite, as well as ubiquitous glomerocrysts of varying magmatic mineral assemblages. In addition, the notable occurrence of magmatic and crustal xenoliths (meta-basalts, amphibole-bearing cumulates, and skarn-type calc-silicates and meta-volcaniclastic rocks) is a distinct feature of the dome. New petrographical, whole rock major and trace element data, mineral chemistry as well as oxygen isotope data for both whole rocks and minerals indicate a complex regime of magma-mixing, decompression-driven resorption, degassing and crystallisation and crustal assimilation within the Kelut plumbing system prior to extrusion of the dome. Detailed investigation of plagioclase textures alongside crystal size distribution analyses provide evidence for magma mixing as a major pre-eruptive process that blends multiple crystal cargoes together. Distinct magma storage zones are postulated, with a deeper zone at lower crustal levels or near the crust-mantle boundary (>15 km depth), a second zone at mid-crustal levels (~10 km depth) and several magma storage zones distributed throughout the uppermost crust (<10 km depth). Plagioclase-melt and amphibole hygrometry indicate magmatic H2O contents ranging from ~8.1 to 8.6 wt.% in the lower crustal system to ~1.5 to 3.3 wt.% in the mid to upper crust. Pyroxene and plagioclase δ18O values range from 5.4 to 6.7 ‰, and 6

    On May 29, 2006, mud and gases began erupting from a vent 150 meters away from a gas exploration well near Sidoarjo, East Java, Indonesia. The eruption, called the LUSI mud volcano, has continued at rates as high as 160,000 m3 per day. At the request of the United States Department of State, the U.S. Geological Survey (USGS) has been providing technical assistance to the Indonesian Government on the geological and geochemical aspects of the mud eruption. This paper will present analytical results of mud samples collected in Sept. 2007 and Nov. 2008, and interpretive findings based on the analytical results. The 2007 mud sample contains high proportions of particles that could be ingestible by hand-mouth transmission (~98 vol % <250 microns,), inhalable into the upper respiratory tract (~80 vol % <10 microns), and respirable into the lung alveoli (~ 40 vol % <2.5 microns), so the mud and dust from the dried mud could be readily taken up by exposed individuals. Our results confirm those of a previous study that the levels of potentially toxic heavy metals or metalloids in the mud are low. A complex mixture of organic compounds in the mud is likely derived from petroleum source rocks. Although the 2007 mud sample contains several percent iron sulfides, net acid production tests indicate that enough carbonate material is also present to prevent the mud from becoming acid-generating due to weathering and sulfide oxidation in the near-surface environment. Water derived from settling mud deposits may have the potential to adversely affect the quality of surface- or groundwater sources for drinking water, due to high levels of fluoride, nitrate, iron, manganese, aluminum, sulfate, chloride, and total dissolved solids. The very high nitrate levels in the waters contained within the mud may present a source of nutrients that could enhance algal blooms and resulting adverse impacts such as hypoxia in fresh-water and marine ecosystems into which some of the mud is being

    Increasingly, landscapes are managed for multiple objectives to balance social, economic, and environmental goals. The Ex-Mega Rice Project (EMRP) peatland in Central Kalimantan, Indonesia provides a timely example with globally significant development, carbon, and biodiversity concerns. To inform future policy, planning, and management in the EMRP, we quantified and mapped ecosystem service values, assessed their spatial interactions, and evaluated the potential provision of ecosystem services under future land-use scenarios. We focus on key policy-relevant regulating (carbon stocks and the potential for emissions reduction), provisioning (timber, crops from smallholder agriculture, palm oil), and supporting (biodiversity) services. We found that implementation of existing land-use plans has the potential to improve total ecosystem service provision. We identify a number of significant inefficiencies, trade-offs, and unintended outcomes that may arise. For example, the potential development of existing palm oil concessions over one-third of the region may shift smallholder agriculture into low-productivity regions and substantially impact carbon and biodiversity outcomes. While improved management of conservation zones may enhance the protection of carbon stocks, not all biodiversity features will be represented, and there will be a reduction in timber harvesting and agricultural production. This study highlights how ecosystem service analyses can be structured to better inform policy, planning, and management in globally significant but data-poor regions. PMID:26255358

    A new clitellate species of Pristininae (Naididae), Pristina armata n. sp., found in the pitcher of the carnivorous plant Nepenthes sp., is reported from East Kalimantan, Indonesia. P. armata n. sp. is a very small clitellate, less than 1 mm long in fixed state, and without proboscis on the prostomium. Signs of reproduction by paratomy were observed, but the generic placement remains preliminary because sexually mature individuals were not found. P. armata n. sp. is characterized by giant hook-like dorsal chaetae at IV. The description of P. armata n. sp. was based on six fixed specimens of different size and stage of development. Noteworthy is the habitat of P. armata n. sp. in Nepenthes pitchers, this being the first clitellate species described from such a habitat. P. armata n. sp. may be a member of the nepenthebionts' community, realizing its life cycle inside the digestive fluid of the Nepenthes pitcher, or it belongs to nepenthephiles, species that commonly occur in this habitat but do not specialize on it.

    Indonesia's fire and haze problem is reviewed, and a model quantifying the relationship between drought and haze from biomass burning in western Indonesia is presented. Visibility observations from weather stations in Sumatra and Kalimantan were used as a haze indicator. The Drought Code component of the Canadian Forest Fire Weather Index System was used as a drought indicator. Using meteorological data from 1994 to 1998, we obtained regional haze and drought signals for western Indonesia. Nonlinear regression analysis was performed between the two signals to obtain a model of haze potential based on the Drought Code. Using the curvature properties of the nonlinear model, we estimated that severe haze is likely above a threshold Drought Code of 388.2. Using this threshold value, we propose four levels of drought that can be used operationally as an early warning tool in managing Indonesia's serious haze problem.

    Scientists at Applied GeoSolutions, Jet Propulsion Laboratory, Winrock International, and the University of New Hampshire are working with the government of Indonesia to enhance the National Forest Monitoring System in Kalimantan, Indonesia. The establishment of a reliable, transparent, and comprehensive NFMS has been limited by a dearth of relevant data that are accurate, low-cost, and spatially resolved at subnational scales. In this NASA funded project, we are developing, evaluating, and validating several critical components of a NFMS in Kalimantan, Indonesia, focusing on the use of LiDAR and radar imagery for improved carbon stock and forest degradation information. Applied GeoSolutions and the University of New Hampshire have developed an Open Source Software package to process large amounts LiDAR data quickly, easily, and accurately. The Open Source project is called lidar2dems and includes the classification of raw LAS point clouds and the creation of Digital Terrain Models (DTMs), Digital Surface Models (DSMs), and Canopy Height Models (CHMs). Preliminary estimates of forest structure and forest damage from logging from these data sets support the idea that comprehensive, well documented, freely available software for processing LiDAR data can enable countries such as Indonesia to cost effectively monitor their forests with high precision.

    Indonesia is a very big country with over 238 million people. And we only have one higher learning institution on astronomy, so how do we reach and convey astronomical information effectively to the whole country? The answer lies in Astronomy Clubs who play an increasingly important role to communicate and educate the public. As part of South East Asia, Indonesia is actively involved in the region to develop astronomy.

  3. Indonesia's migration transition.

    This article describes population movements in Indonesia in the context of rapid and marked social and economic change. Foreign investment in Indonesia is increasing, and global mass media is available to many households. Agriculture is being commercialized, and structural shifts are occurring in the economy. Educational levels are increasing, and women's role and status are shifting. Population migration has increased over the decades, both short and long distance, permanent and temporary, legal and illegal, and migration to and between urban areas. This article focuses specifically on rural-to-urban migration and international migration. Population settlements are dense in the agriculturally rich inner areas of Java, Bali, and Madura. Although the rate of growth of the gross domestic product was 6.8% annually during 1969-94, the World Bank ranked Indonesia as a low-income economy in 1992 because of the large population size. Income per capita is US $670. Indonesia is becoming a large exporter of labor to the Middle East, particularly women. The predominance of women as overseas contract workers is changing women's role and status in the family and is controversial due to the cases of mistreatment. Malaysia's high economic growth rate of over 8% per year means an additional 1.3 million foreign workers and technicians are needed. During the 1980s urban growth increased at a very rapid rate. Urban growth tended to occur along corridors and major transportation routes around urban areas. It is posited that most of the urban growth is due to rural-to-urban migration. Data limitations prevent an exact determination of the extent of rural-to-urban migration. More women are estimated to be involved in movements to cities during the 1980s compared to the 1970s. Recruiters and middlemen have played an important role in rural-to-urban migration and international migration. PMID:12347370

    The population of Indonesia is 175 million, of which 65% live in Java. Java has only 7% of the land area, causing a population density of 2,000/square mile. This has lead the government to introduce a policy of transmigration which encourages people to move from Java to the larger outer islands. In the last 35 years 4.3 million people have moved from Java to Sumatra, Borneo, Celebes, and Irian Jaya. The total area of Indonesia stretches over 3,200 miles and has 16,000 islands of which 1,000 are inhabited. It has vast resources of oil, lumber, rubber, tin, palm oil, copra, coffee, tea, pepper, cloves, nutmeg, and quinine. Indonesia is also rich in minerals, including coal, bauxite, iron ore, and gold. Even with a national family planning program, population growth has reached 2.1% a year. 3 other islands that people are induced to move from are Madura, Bali, and Lombok, although their population densities are less then Java. The small islands near Singapore are being developed and Batam will be a free port to compete with Hong Kong. The most intense migration has been to Kalimantan (Borneo) which has 4 provinces. The migration policy began in 1905 and by 1930 100,000 people, had moved to other islands; 600,000 people were relocated to plantations in Java for labor needs. In 1979-84, a more ambitious program costing 2.3 billion moved 1.5 million people. In the most recent 1984-89 plan, a goal of 3.1 million were to be relocated but due to budgetary restrictions only 150,000 families have moved. The main social issue addresses the domination of other people by Javanese, not only in numbers but cultural differences. Some observers say the real reason for migration is political in ensuring the boundaries and geographic integrity of Indonesia. PMID:12316071

    The worsening environmental situation of the Brantas River, East Java, is addressed by a comprehensive basin management strategy which relies on accurate water quantity and quality data retrieved from a newly installed online monitoring network. Integrated into a Hydrological Information System, the continuously measured indicative parameters allow early warning, control and polluter identification. Additionally, long-term analyses have been initiated for improving modelling applications like flood forecasting, water resource management and pollutant propagation. Preliminary results illustrate the efficiency of the installed system.

    Because of the large-scale destruction of Borneo's rainforests on mineral soils, tropical peat-swamp forests (TPSFs) are increasingly essential for conserving remnant biodiversity, particularly in the lowlands where the majority of habitat conversion has occurred. Consequently, effective strategies for biodiversity conservation are required, which rely on accurate population density and distribution estimates as a baseline. We sought to establish the first population density estimates of the endemic red langur (Presbytis rubicunda) in Sabangau TPSF, the largest remaining contiguous lowland forest-block on Borneo. Using Distance sampling principles, we conducted line transect surveys in two of Sabangau's three principle habitat sub-classes and calculated group density at 2.52 groups km⁻² (95% CI 1.56-4.08) in the mixed-swamp forest sub-class. Based on an average recorded group size of 6.95 individuals, population density was 17.51 ind km⁻², the second highest density recorded in this species. The accessible area of the tall-interior forest, however, was too disturbed to yield density estimates representative of the entire sub-class, and P. rubicunda was absent from the low-pole forest, likely as a result of the low availability of the species' preferred foods. This absence in 30% of Sabangau's total area indicates the importance of in situ population surveys at the habitat-specific level for accurately informing conservation strategies. We highlight the conservation value of TPSFs for P. rubicunda given the high population density and large areas remaining, and recommend 1) quantifying the response of P. rubicunda to the logging and burning of its habitats; 2) surveying degraded TPSFs for viable populations, and 3) effectively delineating TPSF sub-class boundaries from remote imagery to facilitate population estimates across the wider peat landscape, given the stark contrast in densities found across the habitat sub-classes of Sabangau.

    Orangutans (genus Pongo) are the largest arboreal mammals, but Bornean orangutans (P. pygmaeus spp.) also spend time on the ground. Here, we investigate ground use among orangutans using 32,000 hr of direct focal animal observations from a well-habituated wild population of Bornean orangutans (P. p. wurmbii) living in a closed-canopy swamp forest at Tuanan, Central Kalimantan, Indonesia. Ground use did not change with increasing observation time of well-habituated individuals, suggesting it was not an artifact of observer presence. Flanged males spent the most time on the ground (ca. 5% of active time), weaned immatures the least (around 1%). Females and immatures descended mainly to feed, especially on termites, whereas flanged males traveled more while on the ground. Flanged males may travel more inconspicuously, and perhaps also faster, when moving on the ground. In addition, orangutans engaged in ground-specific behavior, including drinking from and bathing in swamp pools. Supplementary records from 20 ground-level camera traps, totaling 3986 trap days, confirmed the observed age-sex biases in ground use at Tuanan. We conclude that ground use is a natural part of the Bornean orangutan behavioral repertoire, however it remains unclear to what extent food scarcity and canopy structure explain population differences in ground use.

  10. Human amplification of drought-related biomass burning in Indonesia since 1960

    Biomass burning in Indonesia is a singularly large source of greenhouse gas emissions at a global scale, with pronounced regional impacts on air quality. Although some fire events have been documented on a case- by-case basis, no continuous record exists prior to 1996, due to the absence of satellite estimates or ground- truthed records of fire extent. Here, we provide a continuous record of severe haze in Indonesia from 1960 to 2006 using the visibility reported at airports, which was found to be an excellent proxy for particulate matter emissions. We used the visibility proxy to show that the haze events in Indonesia were worse, by a factor of five, than extreme periods in cities with the world's worst air quality, and to better understand the underlying climatic and anthropogenic causes of the fire. Large fire events have occurred in Sumatra at least since the 1960s, but in Kalimantan only since the 1980s, despite the occurrence of several severe droughts during 1960- 1980. This difference can be attributed to different patterns of deforestation and population growth, which intensified in Kalimantan only in the 1980s during Indonesia's official program of transmigration. In the presence of intensive land use, there is a non-linear relationship between rainfall and fire, whereby fire events occur only during drought years when rainfall falls below a certain threshold, which we estimated using change-point analysis. Whereas recent fire events have been linked to exclusively El Niño, our long- term record suggests that the Indian Ocean Dipole is equally as, if not more, important a factor. Better understanding of these controls may help to assess future fire risk in Indonesia, which recent studies suggest could increase due to reduced precipitation and accelerated deforestation.

    Dredgings conducted during the French-Indonesian cruises Banda Sea II and III collected volcanic rocks from several ridges of the Banda Sea area (Tukang Besi ridge, site 218; Lucipara ridge, sites 214 and 305; Nieuwerkerk-Emperor of China, sites 219 and 220). With the exception of one 46-Ma-old N-MORB type basalt, thought to belong to an ophiolitic complex, K-Ar and Ar-Ar datings indicate that all the dredged volcanics are Neogene. They range in age from ca. 10 Ma (Tukang Besi back-arc basalts) to 8-7 Ma (Nieuwerkerk-Emperor of China calc-alkaline andesites) and to 7-3 Ma (Lucipara OIB-type transitional basalts and cordierite-bearing andesites). Radiogenic isotopic signatures of andesites are consistent with an AFC (Assimilation coupled with Fractional Crystallization) process involving assimilation of continental crust. 8-3-Ma-old calc-alkaline volcanic activity is also recorded on the Wetar segment, an inactive part of the East Sunda arc, and corresponding isotopic compositions are also consistent with an AFC process involving continental crust. These features suggest that Lucipara-Nieuwerkerk-Emperor of China ridges and the Wetar segment were representing a single volcanic arc 8-7 Ma ago. The corresponding calc-alkaline activity was related to the subduction of the Indian oceanic lithosphere beneath continental blocks of Australian origin. Back-arc opening processes occurred from 6 to 3 Ma as a multi-rift opening for the Wetar basin and as a single-rift opening for the Damar basin while subduction-related magmatism was still active in the Wetar segment. Volcanic activity stopped at 7 Ma in the Nieuwerkerk-Emperor of China ridge. On Lucipara ridge, 6-3 Ma volcanic activity emplaced concomitantly transitional basalts and cordierite-bearing andesites. The mineralogical and chemical features of the latter are consistent with an AFC process involving assimilation of continental crust by mantle-derived basaltic magmas. The end of magmatic activity on both volcanic

    The Java Island is characterized by an intense volcanic activity with more then 100 active volcanoes. Moreover, this island is also known by the presence of many mud volcanoes and hydrothermal springs. In particular, in the 2006 several sudden hot mud eruptions, with fluids around 100° C, occurred in the NE side of the island resulting in a prominent eruption named Lusi (contraction of Lumpur Sidoarjo) located along the major Watukosek strike-slip fault zone. The Watukosek fault system, strikes from the Arjuno-Welirang volcanic complex, intersects Lusi and extends towards the NE of the Java island. Conversely of the normal mud eruptions (cold fluids emitted in a short time period of few days), the Lusi eruption was characterized by a persistent effusive hot fluids emissions for a long-time period of, so far, nearly a decade. Moreover, the isotopic composition of emitted gases like Helium showed a clear magmatic origin. For this reasons we decided to investigate the near Arjuno-Welirang complex located on the same strike-slip fault. Arjuno-Welirang is a twin strato-volcano system located in the East of Java along the Watukosek fault, at about 25 km SW respect to the Lusi volcano system. It features two main peaks: Arjuno (3339 masl) and Welirang (3156 masl). The last recorded eruptive activity took place in August 1950 from the flanks of Kawah Plupuh and in October 1950 from the NW part of the Gunung Welirang. This strato-volcano is characterized by a S-rich area, with high T-vent fumarole at least up to 220° C (and likely higher), located mainly in the Welirang crater. In addition, several hot springs vent from the flanks of the volcano, indicate the presence of a large hydrothermal system. During July 2015, in the framework of the Lusi Lab project (ERC grant n° 308126), we carried out a geochemical field campaign on the Arjuno-Welirang volcano hydrothermal system area, sampling water and dissolved gases from the thermal and cold springs located on the flanks of

    The dominant tectonic-force factor in the Sulawesi Island is the westward Bangga-Sula microplate tectonic intrusion, driven by the 12 mm/year westward motion of the Pacific Plate relative to Eurasia. This tectonic intrusion are accommodated by a series of major left-lateral strike-slip fault zones including Sorong Fault, Sula-Sorong Fault, Matano Fault, Palukoro Fault, and Lawanopo Fault zones. The Lawanopo fault has been considered as an active left-lateral strike-slip fault. The natural exposures of the Lawanopo Fault are clear, marked by the breaks and liniemants of topography along the fault line, and also it serves as a tectonic boundary between the different rock assemblages. Inpections of IFSAR 5m-grid DEM and field checks show that the fault traces are visible by lineaments of topographical slope breaks, linear ridges and stream valleys, ridge neckings, and they are also associated with hydrothermal deposits and hot springs. These are characteristics of young fault, so their morphological expressions can be seen still. However, fault scarps and other morpho-tectonic features appear to have been diffused by erosions and young sediment depositions. No fresh fault scarps, stream deflections or offsets, or any influences of fault movements on recent landscapes are observed associated with fault traces. Hence, the faults do not show any evidence of recent activity. This is consistent with lack of seismicity on the fault.

    Fires associated with agricultural and plantation development in Indonesia impact ecosystem services and release emissions into the atmosphere that degrade regional air quality and contribute to greenhouse gas concentrations. In this study, we estimate the relative contributions of the oil palm, timber (for wood pulp and paper), and logging industries in Sumatra and Kalimantan to land cover change, fire activity, and regional population exposure to smoke concentrations. Concessions for these three industries cover 21% and 49% of the land area in Sumatra and Kalimantan respectively, with the highest overall area in lowlands on mineral soils instead of more carbon-rich peatlands. In 2012, most remaining forest area was located in logging concessions for both islands, and for all combined concessions, there was higher remaining lowland and peatland forest area in Kalimantan (45% and 46%, respectively) versus Sumatra (20% and 27%, respectively). Emissions from all combined concessions comprised 41% of total fire emissions (within and outside of concession boundaries) in Sumatra and 27% in Kalimantan for the 2006 burning season, which had high fire activity relative to decadal emissions. Most fire emissions were observed in concessions located on peatlands and non-forested lowlands, the latter of which could include concessions that are currently under production, cleared in preparation for production, or abandoned lands. For the 2006 burning season, timber concessions from Sumatra (47% of area and 88% of emissions) and oil palm concessions from Kalimantan (33% of area and 67% of emissions) contributed the most to concession-related fire emissions from each island. Although fire emissions from concessions were higher in Kalimantan, emissions from Sumatra contributed 63% of concession-related smoke concentrations for the population-weighted region because fire sources were located closer to population centers. In order to protect regional public health, our results

    In response to unsustainable timber production in tropical forest concessions, voluntary forest management certification programs such as the Forest Stewardship Council (FSC) have been introduced to improve environmental, social, and economic performance over existing management practices. However, despite the proliferation of forest certification over the past two decades, few studies have evaluated its effectiveness. Using temporally and spatially explicit village-level data on environmental and socio-economic indicators in Kalimantan (Indonesia), we evaluate the performance of the FSC-certified timber concessions compared to non-certified logging concessions. Employing triple difference matching estimators, we find that between 2000 and 2008 FSC reduced aggregate deforestation by 5 percentage points and the incidence of air pollution by 31%. It had no statistically significant impacts on fire incidence or core areas, but increased forest perforation by 4 km2 on average. In addition, we find that FSC reduced firewood dependence (by 33%), respiratory infections (by 32%) and malnutrition (by 1 person) on average. By conducting a rigorous statistical evaluation of FSC certification in a biodiversity hotspot such as Indonesia, we provide a reference point and offer methodological and data lessons that could aid the design of ongoing and future evaluations of a potentially critical conservation policy.

    Smoke-haze episodes caused by vegetation and peat fires affect parts of Indonesia every year with significant impacts on human health and climate. The forest fires 1997/1998 were by far the largest in Indonesian history, burning between 5 and 8 million hectares before they were stopped by the monsoon rains in December 1997. Fires sprang up again in 1998 on Kalimantan when monsoon rain paused. Peat forests and peatlands are in particular severely affected. In the 1997/1998 haze event, 2.1-2.5 million hectare of peat swamp forest burnt in Indonesia. The remaining ash contains high concentrations of sulphur and sulphuric compounds which eventually leach into the groundwater, thus polluting groundwater and drinking water. The thicker the peat layer is and the higher the number of fires in the respective area the more sulphuric compounds will leach into the groundwater. Risk areas for the sulphur loads of the ash are identified.

The forest fires 1997/1998 were by far the largest in Indonesian history, burning between 5 and 8 million hectares before they were stopped by the monsoon rains in December 1997. Fires sprang up again in 1998 on Kalimantan when monsoon rain paused. Peat forests and peatlands are in particular severely affected. In the 1997/1998 haze event, 2.1-2.5 million hectare of peat swamp forest burnt in Indonesia. The remaining ash contains high concentrations of sulphur and sulphuric compounds which eventually leach into the groundwater, thus polluting groundwater and drinking water. The thicker the peat layer is and the higher the number of fires in the respective area the more sulphuric compounds will leach into the groundwater. Risk areas for the sulphur loads of the ash are identified. PMID:17711022

    Optical and chemical studies of maceral concentrates from a Miocene lignite and an Eocene high-volatile bituminous C coal from southeastern Kalimantan, Indonesia were undertaken using pyro-Lysis, optical, electron microprobe and FTIR techniques Pyrolysis products of vitrinite from bituminous coal were dominated by straight-chain aliphatics and phenols. The huminite of the Miocene lignite produced mostly phenolic compounds upon pyrolysis. Differences in the pyrolysis products between the huminite and vitrinite samples reflect both maturation related and paleobotanical differences. An undefined aliphatic source and/or bacterial biomass were the likely contributors of n-alkyl moieties to the vitrinite. The resinite fraction in the lignite yielded dammar-derived pyrolysis products, as well as aliphatics and phenols as the products of admixed huminite and other liptinites. The optically defined resinite-rich fraction of the bituminous coal from Kalimantan produced abundant n-aliphatic moieties upon pyrolysis, but only two major resin markers (cadalene and 1,6-dimethylnaphthalene). This phenomenon is likely due to the fact that Eocene resins were not dammar-related. Data from the electron microprobe and Fourier transform infrared spectrometry strongly support the results obtained by Py GC MS and microscopy.

    Much of the interannual variability in global atmospheric carbon dioxide concentrations has been attributed to variability of emissions from biomass burning. Under drought conditions, agricultural burning in Indonesia escapes control, and is a disproportionate contributor to these emissions, as seen in the 1997/98 haze disaster. Yet our understanding of the frequency, severity and underlying causes of severe biomass burning in Indonesia is limited because of the absence of satellite data that are useful for fire monitoring before the mid- 1990s. Here we present a continuous monthly record of severe burning events from 1960 to 2006 using the visibility reported at airports in the region. We find that these fires cause what are possibly the world's worst air quality conditions and that they occur only during years when precipitation falls below a well defined threshold. Historically, large fire events have occurred in Sumatra at least since the 1960s. By contrast, the first large fires are recorded in Kalimantan (Indonesian Borneo) in the 1980s, despite earlier severe droughts. We attribute this difference to different patterns of changes in land use and population density. Fires in Indonesia have often been linked with El Niño, but we find that the Indian Ocean Dipole pattern is as important a contributing factor.

    In this first study of lignin geochemistry in the world's longest river on an island, surface sediments were collected along the Kapuas River, three lakes in the upper river, a tributary in the lower river and a separate river during June-July 2007 and December 2007-January 2008. The samples were analyzed for lignin-derived phenols and bulk elemental and stable carbon isotope compositions. Λ values (the sum of eight lignin phenols, expressed as mg/100 mg organic carbon (OC)) ranged from 0.13 to 3.70. Ratios of syringyl/vanillyl (S/V) and cinnamyl/vanillyl (C/V) ranged from 0.34 to 1.18 and 0.28 to 1.40, respectively, indicating the presence of non-woody angiosperm tissues. The high vanillic acid to vanillin (Ad/Al)v (0.71-2.01) and syringic acid to syringaldehyde (Ad/Al)s (0.72-2.12) ratios indicate highly degraded lignin materials. In the upper Kapuas River, highly degraded soil materials discharged from lands that were barren as a result of deforestation activities were detected in the locations directly in those vicinities. The middle Kapuas River showed rapid organic matter degradation, probably due to the presence of fresh terrestrial and phytoplankton organic matter fueling the biogeochemical cycling. The Kapuas Kecil River, one of the two branches in the lower reach of the Kapuas River, showed higher levels and diagenesis of sedimentary organic matter due to input from anthropogenic sources and increased marine organic matter near the mouth. This study shows that different stretches along the river exhibit different levels and composition of sedimentary organic matter, as well as different carbon dynamics, which is directly attributable to the varying landscapes and quality of organic matter.

Information regarding Indonesia obtained from World Bank Report and Statistical Yearbook of Indonesia 2007, epidemiological data obtained from Histopathological Data of Cancer in Indonesia 2002, Department of Health-Registry Body of Indonesian Specialist of Pathology Association-Indonesian Cancer Society; Various Hospitals in big Cities in Indonesia. Indonesia is an Archipelago with a total area of 1,922,570.00 km(2), the population is 222,192,000 (2006), the fourth world rank. Female is 49.86% with life expectancy 69 years. Gross National Product per Capita is 690.00 USD. Histopathological report in 2002 revealed that cervical cancer, ovarian cancer and uterine cancer were the most frequent cancer among female, which were the first (2,532 cases), the third (829 cases) and the eighth (316 cases) rank respectively. The peak age for cervical, uterine and ovarian cancer was 45-54 years. HPV 16, 18 were found in 82% of invasive cervical. Data from various academic hospitals in 2007 showed that cervical cancer is the most common malignancy followed by ovary, uterus, vulva and vagina. Five-year survival rate of stage I, II, III, IV cervical cancer were 50%, 40%, 20%, and 0% respectively. Overall five-year survival rate of carcinoma of the ovary was 54.8%. If sub-classified by stage, five-year survival rate are 94.3%, 75.0%, 31%, and 11.7% for stage I, II, III, and IV respectively. Five-year disease-free survival rate of endometrial cancer was 71.9%. Indonesia is the biggest Archipelago with a dense population but the income per capita still low (poor country). The most common gynecologic cancer is cervical cancer, followed by ovarian and uterine cancer. These cancers are included in top ten cancers in Indonesia. HPV 16, 18 were the most cause of cervical cancer. The five-year survival rates are comparable with world report.

    The development of an operational water quality monitoring method based on remote sensing data requires information on the apparent and inherent optical properties of water (AOP and IOP respectively). This study was performed to determine the apparent and inherent optical properties of coastal waters of the Mahakam Delta, Kalimantan, Indonesia. Inherent optical properties (IOPs) were derived from above-water radiometric measurements and ocean color model inversion. Retrieved IOPs and measured concentrations show good agreement both for total suspended matter (TSM) and chlorophyll a (Chl a) (R2 = 0.72 and 0.80 respectively). The linear relationship between the retrieved IOPs and the measured concentrations was then used to estimate the specific inherent optical properties (SIOPs) using the basic equation of the Lambert-Beer law. The specific backscattering coefficient of TSM (bb,TSM∗(550)) was found to be 0.0087 m2 g-1, and the specific absorption coefficient of Chl a (aChl∗(440)) was found to be 0.023 m2 g-1 in the Mahakam Delta. The estimated values of SIOP for TSM and Chl a could be considered spatially constant for the Mahakam Delta, and resulted in reliable estimates of TSM and Chl a concentrations (R2 = 0.84 and 0.85 respectively). The specific backscattering coefficient of TSM found in this study is similar to that of the Barito Estuary (in the southern part of Kalimantan) but lower than that of the Berau Estuary (in the northern part of Kalimantan), whereas the specific backscattering coefficient of Chl a is similar to that found in the Berau Estuary. This study contributes to the development of an operational method based on remote sensing data to map water constituent concentrations in the Mahakam Delta, as well as to enrich the information about the optical properties of Indonesian waters.

    During the dry season, biomass burning is an important source of ozone precursors for the tropical troposphere, and ozone formation can occur in biomass burning plumes originating in Indonesia and northern Australia. Satellite based GOME (Global Ozone Measuring experiment) data are used to characterize the amount of tropospheric ozone production over this region during the El Niño event in September 1997 compared to a so called "normal" year 1998. Large scale biomass burning occurred over Kalimantan in 1997 caused by the absence of the northern monsoon rains, leading to significant increases in tropospheric ozone. Tropospheric ozone was determined from GOME data using the Tropospheric Excess Method (TEM). Backtrajectory calculations show that Indonesia is influenced every summer by the emissions of trace gases from biomass buring over northern Australia. But in 1997 over Indonesia an increasing of tropospheric ozone amounts can be observed caused by the fires over Indonesia itself as well as by northern Australia. The analysis of the measurements of BIBLE-A (Biomass Burning and Lightning Experiment) and using ATSR (Along the Track Scanning Radiometer) data show differences in the view to the intensity of fire counts and therefore in the amount of the emission of precursors of tropospheric ozone comparing September 1997 to September 1998.

    Non-communicable diseases, including cancer, start to become more common in Indonesia. According to the government statement, incidence of malignant diseases increased annually up to 8% in the last decade and these diseases become the seventh leading cause of death in Indonesia. On the basis of the latest Globocan report on cancer incidence in Indonesia, prostate cancer ranks sixth; followed by bladder (12th) and kidney (18th). More than half of patients with kidney cancer are diagnosed in the advanced stage. Besides renal cell carcinoma, there are significant number of people affected with squamous cell and transitional cell carcinoma because of kidney stones. Radical nephrectomy or cytoreductive nephrectomy was the primary treatment, mostly done as an open procedure. Transitional cell carcinoma is the commonest histology type in bladder cancer cases followed by squamous cell carcinoma, which almost always related to bladder stones. Unfortunately, >70% of our cases were diagnosed with muscle invasive bladder cancer, and ∼60% of these patients refused further radical treatment. Incidence of prostate cancer is increasing rapidly and it becomes the third most common cancer in men. However, most of our patients are diagnosed in the advanced stage. Radical prostatectomy or external beam radiotherapy is the treatment of choice in localized disease. Nearly 40% of the elderly patients are treated with primary androgen deprivation therapy. Therefore, it requires more research by the Indonesian urologists and other healthcare providers to diagnose these cancers in earlier stage as well as community education for prevention.

    Tropical peatland could be a source of greenhouse gases emission because it contains large amounts of soil carbon and nitrogen. However these emissions are strongly influenced by soil moisture conditions. Tropical climate is characterized typically by wet and dry seasons. Seasonal changes in the emission of carbon dioxide (CO(2)), methane (CH(4)) and nitrous oxide (N(2)O) were investigated over a year at three sites (secondary forest, paddy field and upland field) in the tropical peatland in South Kalimantan, Indonesia. The amount of these gases emitted from the fields varied widely according to the seasonal pattern of precipitation, especially methane emission rates were positively correlated with precipitation. Converting from secondary forest peatland to paddy field tended to increase annual emissions of CO(2) and CH(4) to the atmosphere (from 1.2 to 1.5 kg CO(2)-C m(-2)y(-1) and from 1.2 to 1.9 g CH(4)-C m(-2)y(-1)), while changing land-use from secondary forest to upland tended to decrease these gases emissions (from 1.2 to 1.0 kg CO(2)-C m(-2)y(-1) and from 1.2 to 0.6 g CH(4)-C m(-2)y(-1)), but no clear trend was observed for N(2)O which kept negative value as annual rates at three sites.

    Fire emissions associated with land cover change and land management contribute to the concentrations of atmospheric pollutants, which can affect regional air quality and climate. Mitigating these impacts requires a comprehensive understanding of the relationship between fires and different land cover change trajectories and land management strategies. We develop future fire emissions inventories from 2010-2030 for Sumatra and Kalimantan (Indonesian Borneo) to assess the impact of varying levels of forest and peatland conservation on air quality in Equatorial Asia. To compile these inventories, we combine detailed land cover information from published maps of forest extent, satellite fire radiative power observations, fire emissions from the Global Fire Emissions Database, and spatially explicit future land cover projections using a land cover change model. We apply the sensitivities of mean smoke concentrations to Indonesian fire emissions, calculated by the GEOS-Chem adjoint model, to our scenario-based future fire emissions inventories to quantify the different impacts of fires on surface air quality across Equatorial Asia. We find that public health impacts are highly sensitive to the location of fires, with emissions from Sumatra contributing more to smoke concentrations at population centers across the region than Kalimantan, which had higher emissions by more than a factor of two. Compared to business-as-usual projections, protecting peatlands from fires reduces smoke concentrations in the cities of Singapore and Palembang by 70% and 40%, and by 60% for the Equatorial Asian region, weighted by the population in each grid cell. Our results indicate the importance of focusing conservation priorities on protecting both forested (intact or logged) peatlands and non-forested peatlands from fire, even after considering potential leakage of deforestation pressure to other areas, in order to limit the impact of fire emissions on atmospheric smoke concentrations and

Here we report three cases of melioidosis in Makassar, South Sulawesi, Indonesia occurring between 2013 and 2014. Two patients died and the other was lost to follow-up. Burkholderia pseudomallei isolates from all three cases were identified by the VITEK2 Compact installed in the hospital in 2012. None of the three patients reported received antimicrobials recommended for melioidosis because of the delayed recognition of the organism. We reviewed the literature and found only seven reports of melioidosis in Indonesia. Five were reported before 1960. We suggest that melioidosis is endemic throughout Indonesia but currently under-recognized. Training on how to identify B. pseudomallei accurately and safely in all available microbiological facilities should be provided, and consideration should be given to making melioidosis a notifiable disease in Indonesia.

    Volcanological investigations in Indonesia were started in the 18th century, when Valentijn in 1726 prepared a chronological report of the eruption of Banda Api volcno, Maluku. Modern and intensive volcanological studies did not begin until the catastrophic eruption of Kelut volcano, East Java, in 1919. The eruption took 5,011 lives and destroyed thousands of acres of coffee plantation. An eruption lahar generated by the crater lake water mixed with volcanic eruptions products was the cause of death for a high number of victims. An effort to mitigate the danger from volcanic eruption was first initiated in 1921 by constructing a tunnel to drain the crater lake water of Kelut volcano. At the same time a Volcanological Survey was established by the government with the responsibility of seeking every means for minimizing the hazard caused by volcanic eruption.

    Tropical peatlands are one of the largest near-surface reserves of terrestrial organic carbon, and hence their stability has important implications for climate change. In their natural state, lowland tropical peatlands support a luxuriant growth of peat swamp forest overlying peat deposits up to 20 metres thick. Persistent environmental change-in particular, drainage and forest clearing-threatens their stability, and makes them susceptible to fire. This was demonstrated by the occurrence of widespread fires throughout the forested peatlands of Indonesia during the 1997 El Niño event. Here, using satellite images of a 2.5 million hectare study area in Central Kalimantan, Borneo, from before and after the 1997 fires, we calculate that 32% (0.79 Mha) of the area had burned, of which peatland accounted for 91.5% (0.73 Mha). Using ground measurements of the burn depth of peat, we estimate that 0.19-0.23 gigatonnes (Gt) of carbon were released to the atmosphere through peat combustion, with a further 0.05 Gt released from burning of the overlying vegetation. Extrapolating these estimates to Indonesia as a whole, we estimate that between 0.81 and 2.57 Gt of carbon were released to the atmosphere in 1997 as a result of burning peat and vegetation in Indonesia. This is equivalent to 13-40% of the mean annual global carbon emissions from fossil fuels, and contributed greatly to the largest annual increase in atmospheric CO(2) concentration detected since records began in 1957 (ref. 1).

    The elemental composition of individual aerosol particles of 0.15-3 μm radius, collected over Kalimantan during the 1997 Indonesian forest fire event, was analyzed using a transmission electron microscope equipped with an energy-dispersive X-ray analyzer (EDX). Although 60-90% of the particles collected at altitudes of 1-5 km contained K, they exhibited high weight ratios of S/K with median values of 9-18 independent of particle size. These were much larger than those (median values of 2-4) obtained from the forest fires in northern Australia. The high weight ratios over Kalimantan are considered to be due to the heterogeneous growth of particles through the oxidation of SO 2. In addition to SO 2 from the combustion of forest biomass, SO 2 originating from the combustion of peat below the ground is believed to have been important in producing the high S/K ratios.

    The great archipelago in Indonesia with its wealthy and various nature, the products and commodities of tropic agriculture and the rich soil, was through the centuries a region of interest for other countries all over the world. For several reasons some of these countries came to Indonesia to establish their existence and tried to monopolize the trading. These countries such as the Portuguese, the Spanish, the Dutch and the British built strengthened trade stations which later became forts all over Indonesia to defend their interest. The archipelago of Indonesia possesses a great number of fortification-works as legacies of native rulers and those which were built by European trading companies and later became colonial powers in the 16th to the 19th centuries. These legacies include those specific structures built as a defence system during pre and within the period of World War II. These fortresses are nowadaysvaluable subjects, because they might be considered as shared heritage among these countries and Indonesia. It's important to develop a vision to preserve these particular subjects of heritage, because they are an interesting part of the Indonesian history and its cultural treasures. The Government of the Republic of Indonesia has national program to compile a comprehensive documentation of the existing condition of these various types of forts as cultural heritage. The result of the 3 years project was a comprehensive 442 forts database in Indonesia, which will be very valuable to the implementation of legal protection, preservation matters and adaptive re-use in the future.

    include the possibilities of environmental damage due to the high intensity electromagnetic energy from outer space. As is well known, most Indonesian land areas consist of tropical forest which is rich with flora and fauna; these may face risks from receiving such electromagnetic energy illumination. It is considered that rectenna location selection in the main islands (like Java, Sumatra, Kalimantan, Sulawesi, Irian, etc.) which are densely populated should be avoided. The same conditions should also be considered for the location in the forest, due to the flora and fauna damage possibilities during the physical development process. From this study it can be considered that the appropriate rectenna location should be placed on uninhabited small coral islands (atoll) sized about 5x5 km 2 , which are located along the equator. Such coral islands are vailable in the western and eastern parts of Indonesia. It is also considered that such coral islands should be located not too far from major inhabited islands, that is about 5-10 km offshore due to the convenience of physical rectenna development and electric energy distribution to the mainland. Such a coral island is to be considered to suffer minimal effects if the surface is illuminated by microwave energy. The same effect suffered by resident creatures like birds and reptiles should also be minimal. Because of the very limited infrastructure available on the mainland (and likely no facilities at all), a rectenna development study should consider all technical risks. For example, antenna installation and building of other support components should be done in such a location so that sea surface transportation can be easily performed. Communication system may be performed only by radio transceivers and satellite systems. The existence of human resources, that are needed to physically develop buildings, must be considered since the location is a remote island. There will also be no expert staff available, so that they will

    In Indonesia, rapid economic development has led to a reduction in poverty among the 195 million inhabitants. While population increased more than 50% from 1971 to 1990, the annual growth rate, crude birth rate, and total fertility rates have declined rapidly. Life expectancy has increased from 45.7 years in 1971 to 62.7 in 1994 as crude death rates and infant and child mortality rates have declined. Causes of death have shifted from infectious to chronic diseases, but in 1992 major causes of death in children under 5 years old were preventable, and the maternal mortality rate was 425/100,000. Policies which guide the development of health care call for improvements in quality of life, adherence to humanitarian principles, use of scientifically approved traditional medicine, and provision of public health through a three-tiered system. Health care is financed by the government and the community, and managed care has been encouraged. Foreign aid has bolstered development in the health sector. Adequate sanitation has been achieved for 35% of the population, and 65% of urban and 35% of rural residents have reasonable access to clean water. Improvements in health indicators include 55% contraceptive prevalence, reduction in prevalence of anemia during pregnancy, 55.8% of pregnant women receiving prenatal care, a decrease in protein-energy malnutrition among children under five, and high vaccination coverage. Remaining public health problems include malaria, tuberculosis, dengue hemorrhagic fever, an increase in HIV/AIDS, iodine-deficiency, an increasing number of traffic fatalities, and an increasing number of smokers. New health policies have been instituted to meet these challenges as Indonesia's need for a productive and competitive labor force increases.

  12. Family planning Indonesia.

    The growth of family planning activities in Indonesia in the Postwar period is traced; and future prospects for family planning are assessed. Transmigration projects initiated by the Dutch and supported by President Sukarno after Indonesian independence as a means of decreasing population pressure on the island of Java, are identified as the only official response to the population problem until 1965. In the face of the government's opposition to the idea of birth control as a population control measure, the activities of the Indonesian Planned Parenthood Association (IPPA) after its founding in 1957 were limited to advising mothers on spacing of their children for health reasons. Statements made in support of a national family planning program by government officials at a 1967 IPPA Congress and on other occasions are noted. The major components of an approved national family planning program to start in 1969 are described. However, the government's policy as of late 1967 and early 1968 is characterized as one of mainly benevolent encouragement and help to voluntary organizations. The chief impediment to family planning in Indonesia is said to be a lack of motivation and the force of traditional values that favor large families. On the positive side are: 1) Studies showing considerable interest in birth control by the rural population; 2) A long history of traditional birth control practices; 3) The absence of outright opposition by religious groups to the principle of family planning. However, financial costs, the need for the training of personnel, and a general unawareness of the magnitude of the task lying ahead constitute other formidable obstacles.

    Evaluation of CO2 flux from peatland soil respiration is important to understand the effect of land use change on the global carbon cycle and climate change and particularly to support carbon emission reduction policies. However, quantitative estimation of emitted CO2 fluxes in Indonesia is constrained by existing field data. Current methods for CO2 measurement are limited by high initial cost, manpower, and the difficulties associated with construction issues. Measurement campaigns were performed using a newly developed nocturnal temperature-inversion trap method, which measures the amount of CO2 trapped beneath the nocturnal inversion layer, in the dry season of 2013 at a drained tropical peatland near Palangkaraya, Central Kalimantan, Indonesia. This method is cost-effective and data processing is easier than other flux estimation methods. We compared CO2 fluxes measured using this method with the published data from the existing eddy covariance and closed chamber methods. The maximum value of our measurement results was 10% lower than maximum value of eddy covariance method and average value was 6% higher than average of chamber method in drained tropical peatlands. In addition, the measurement results shows good correlation with groundwater table. The results of this comparison suggest that this methodology for the CO2 flux measurement is useful for field research in tropical peatlands.

    Smoldering peat fires in Indonesia are responsible for large quantities of trace gas and particulate emissions. However, to date no satellite remote sensing technique has been demonstrated for the identification of smoldering peat fires. Fires have two distinct combustion phases: a high temperature flaming and low temperature smoldering phases. The flaming phase temperature is approximately twice that of the smoldering phase. This temperature differential results in a spectral displacement of the primary radiant emissions of the two combustion phases. It it is possible to exploit this spectral displacement using widely separated wavelength ranges. This paper examines active fire features found in short-wave infrared (SWIR) and long-wave infrared (LWIR) nighttime Landsat data collected on peatlands in Sumatra and Kalimantan. Landsat 8’s SWIR bands are on the leading edge of flaming phase radiant emissions, with only minor contribution from the smoldering phase. Conversely, Landsat 8’s LWIR bands are on the trailing edge of smoldering phase radiant emissions. After examining the LWIR fire features, we conclude that they are the result of smoldering phase combustion. This has been confirmed with field validation. Detection limits for smoldering peat fires in Landsat 8 is in the 40-90 m2 range. These results could lead to improved management of peatland fires and emission modeling.

    Approximately 230 million people live in Indonesia. The country is also home to over 20 anopheline vectors of malaria which transmit all four of the species of Plasmodium that routinely infect humans. A complex mosaic of risk of infection across this 5000-km-long archipelago of thousands of islands and distinctive habitats seriously challenges efforts to control malaria. Social, economic and political dimensions contribute to these complexities. This chapter examines malaria and its control in Indonesia, from the earliest efforts by malariologists of the colonial Netherlands East Indies, through the Global Malaria Eradication Campaign of the 1950s, the tumult following the coup d’état of 1965, the global resurgence of malaria through the 1980s and 1990s and finally through to the decentralization of government authority following the fall of the authoritarian Soeharto regime in 1998. We detail important methods of control and their impact in the context of the political systems that supported them. We examine prospects for malaria control in contemporary decentralized and democratized Indonesia with multidrug-resistant malaria and greatly diminished capacities for integrated malaria control management programs.

    This article addresses two dimensions of the complex interrelationship between the family and international labor migration in Indonesia: the role of the family in influencing labor movements out of Indonesia; and the consequences of this movement on family well-being, structure, and functioning. Research on this topic in Indonesia is highly limited due mainly to the recency of large scale international labor migration, inadequate data collection systems, a high incidence of undocumented migration, and failure of available research to be sensitive to family related issues. Against a rapidly changing economic and social situation, two major overlapping systems of migration have developed. The official system is focused strongly on the Middle East (although other Asian destinations are increasing in significance) and is dominated by female migrants. The undocumented system is much larger in volume, is focused upon Malaysia, involves more males than females, and is becoming permanent in some cases. The role, status, and experiences of women migrants in relation to their families (decision making, networks, remittances) are discussed with recommendations for other areas needing further research attention.

    Biomass burning is a significant source of fine particulate matter (PM2.5). Forest, bush, and peat fires in Kalimantan and Sumatra, Indonesia are major sources of transboundary haze pollution in Southeast Asia. However, limited data exist regarding the chemical characteristics of aerosols at sources. We conducted intensive field studies in Riau Province, Sumatra, Indonesia, during the peatland fire and non-burning seasons in 2012. We characterized PM2.5 carbonaceous aerosols emitted from peatland fire based on ground-based source-dominated sampling. PM2.5 aerosols were collected with two mini-volume samplers using Teflon and quartz fiber filters. Background aerosols were also sampled during the transition period between the non-burning and fire seasons. We analyzed the carbonaceous content (organic carbon (OC) and elemental carbon (EC)) by a thermal optical reflectance utilizing the IMPROVE_A protocol and the major organic components of the aerosols by a gas chromatography/mass spectrometry. PM2.5 aerosols emitted from peatland fire were observed in high concentrations of 7120 ± 3620 μg m-3 and were primarily composed of OC (71.0 ± 5.11% of PM2.5 mass). Levoglucosan exhibited the highest total ion current and was present at concentrations of 464 ± 183 μg m-3. The OC/EC ratios (36.4 ± 9.08), abundances of eight thermally-derived carbon fractions, OC/Levoglucosan ratios (10.6 ± 1.96), and Levoglucosan/Mannosan ratios (10.6 ± 2.03) represent a signature profile that is inherent in peatland fire. These data will be useful in identifying contributions from single or multiple species in atmospheric aerosol samples collected from peatland fires.

    Timely and accurate data on forest change within Indonesia is required to provide government, private and civil society interests with the information needed to improve forest management. The forest clearing rate in Indonesia is among the highest reported by the United Nations Food and Agriculture Organization (FAO), behind only Brazil in terms of forest area lost. While the rate of forest loss reported by FAO was constant from 1990 through 2005 (1.87 Mha yr-1), the political, economic, social and environmental drivers of forest clearing changed at the close of the last century. We employed a consistent methodology and data source to quantify forest clearing from 1990 to 2000 and from 2000 to 2005. Results show a dramatic reduction in clearing from a 1990s average of 1.78 Mha yr-1 to an average of 0.71 Mha yr-1 from 2000 to 2005. However, annual forest cover loss indicator maps reveal a near-monotonic increase in clearing from a low in 2000 to a high in 2005. Results illustrate a dramatic downturn in forest clearing at the turn of the century followed by a steady resurgence thereafter to levels estimated to exceed 1 Mha yr-1 by 2005. The lowlands of Sumatra and Kalimantan were the site of more than 70% of total forest clearing within Indonesia for both epochs; over 40% of the lowland forests of these island groups were cleared from 1990 to 2005. The method employed enables the derivation of internally consistent, national-scale changes in the rates of forest clearing, results that can inform carbon accounting programs such as the Reducing Emissions from Deforestation and Forest Degradation in Developing Countries (REDD) initiative.

    At least once a year for a period lasting from a week to several months, northern Sumatra is obscured by smoke and haze produced by agricultural burning and forest fires. These data products from the Multi-angle Imaging SpectroRadiometer document the presence of airborne particulates on March 13, 2002, during Terra orbit 11880. On the left is an image acquired by MISR's 70-degree backward-viewing camera. On the right is a map of aerosol optical depth, a measure of the abundance of atmospheric particulates. This product utilized a test version of the MISR retrieval that incorporates an experimental set of aerosol mixtures. The haze has completely obscured northeastern Sumatra and part of the Strait of Malacca, which separates Sumatra and the Malaysian Peninsula. A northward gradient is apparent as the haze dissipates in the direction of the Malaysian landmass. Each panel covers an area of about 760 kilometers x 400 kilometers.

    Haze conditions had posed a health concern during late February (when schools in some parts of North Sumatra were closed), and worsened considerably in the first two weeks of March. By mid-March, local meteorology officials asked residents of North Sumatra's provincial capital, Medan, to minimize their outdoor activities and wear protective masks. Poor visibility at Medan airport forced a passenger plane to divert to Malaysia on March 14, and visibility reportedly ranged between 100 and 600 meters in some coastal towns southeast of Medan.

    The number and severity of this year's fires was exacerbated by dry weather conditions associated with the onset of a weak to moderate El Nino. The governments of Indonesia, Malaysia, and Brunei have agreed to ban open burning in plantation and forest areas. The enforcement of such fire bans, however, has proven to be an extremely challenging task.

    Despite the worldwide oil glut and the resulting slowdown in exploration, the Far East region maintained a relatively high level of activity in 1985. Seismic acquisition nearly doubled, and exploratory drilling declined by only 8%. India, Pakistan, and Republic of China showed a significant increase in wildcat drilling. Multiple discoveries of modest sizes were made in India, Indonesia, Pakistan, and People's Republic of China. New acreage awards were high in Japan, Pakistan, People's Republic of China, and Thailand. However, Indonesia, one of the most active countries in the region, offered no new acreage. Oil production was up by about 2% (620,000 BOPD), and gas output increased by 7% (625 MMCFGD). Crude production declined in Brunei, Indonesia, and Malaysia, which was offset by increased output in People's Republic of China. Development drilling was up by 42%, mostly due to increased drilling in People's Republic of China. 32 figures, 9 tables.

    The Indonesian archipelago encompasses a wide range of tectonic environments, including island arc volcanism, subduction zones, and arc-continent collision. Many of the details of this tectonic activity are still poorly understood, especially where the Australian continent collides with Indonesia, separating the Sunda Arc in west from that at the Banda Arc in the east. While it seems clear that the Australian plate is subducted under both the Sunda and Banda Arcs, it is not clear what happens along the 1000 km -long stretch in between. The question of just where the plate motion is accommodated is of major importance to assessments of earthquake and tsunami hazard in the region. To help resolve these questions the Geospatial Information Agency of Indonesia has collaborated with the Australian National University and the Bandung Institute of Technology in a GPS campaign spanning much of eastern Indonesia, from Lombok in the west to Alor in the east. We have combined these data with those from previous campaigns, resulting in over 27 campaign and 18 continuous GPS sites being used in the analysis. The improvement in site density allowed us to develop of a more complete description of tectonic activity in this region than has been obtained in previous studies. Our preliminary results suggests that there is a relatively simple transition from subduction at the Java Trench off east Java, to a partitioned convergence along both the Timor Trough and the Flores Thrust in the Nusa Tenggara region.

    Current estimates of carbon (C) storage in peatland systems worldwide indicate tropical peatlands comprise about 15% of the global peat carbon pool. Such estimates are uncertain due to data gaps regarding organic peat soil thickness and C content. Indonesian peatlands are considered the largest pool of tropical peat carbon (C), accounting for an estimated 65% of all tropical peat while being the largest source of carbon dioxide emissions from degrading peat worldwide, posing a major concern regarding long-term sources of greenhouse gases to the atmosphere. We combined a set of indirect geophysical methods (ground penetrating radar, GPR, and electrical resistivity imaging, ERI) with direct observations from core samples (including C analysis) to better understand peatland thickness in West Kalimantan (Indonesia) and determine how geophysical imaging may enhance traditional coring methods for estimating C storage in peatland systems. Peatland thicknesses estimated from GPR and ERI and confirmed by coring indicated variation by less than 3% even for small peat-mineral soil interface gradients (i.e. below 0.02°). The geophysical data also provide information on peat matrix attributes such as thickness of organomineral horizons between peat and underlying substrate, the presence of wood layers, buttressed trees and soil type. These attributes could further constrain quantification of C content and aid responsible peatland management in Indonesia.

    From epidemiological point of view, Indonesia is an extremely interesting area owing its insular structure and ecological, anthropological, cultural and economical diversity. As everywhere, vector-borne diseases are the result of complex and variable epidemiological systems, subject both to biogeographical rules and human activity. Two main arboviroses are present in Indonesia: dengue and Japanese encephalitis. Dengue appears as an endemoepidemic disease and is mostly circumscribed to urban areas. Haemorrhagic cases were first observed in 1968; since then, the incidence has been constantly increasing and the disease is now one of the principal causes of child lethality. Japanese encephalitis is a rural endemic disease transmitted by rice-field mosquitoes; its incidence remains relatively low since pigs, which are usual link-hosts for the virus, are uncommon in this mainly Muslem country. Human clinical cases are recorded from non-Muslem islands such as Bali or Irian Jaya which raises the question of immunisation for travellers. Recently, Japanese encephalitis was observed on east of the Wallace line which had been considered as the eastern cut-off line. Malaria is common throughout the country, Plasmodium vivax being the most frequent species. Some of the Anopheline vectors are related to brackish water as are coastal species; others have been favoured by rice growing. Several species bite and rest outdoors, rendering control measures complex. Moreover, chloroquine resistance is increasing in both P. falciparum and P. vivax. All three filaria species responsible for human lymphatic filariasis exist in Indonesia. Bancroft filariasis is present in rather limited foci on most of the islands; malayan filariasis is very prevalent on many islands, mostly in coastal areas, and Timor filariasis exist only on a few small islands. These parasitic diseases are cumulative and do not practically endanger the health of travellers. In the past, plague was common on Java island

    We combined data from a population-based longitudinal survey with satellite measures of aerosol levels to assess the impact of smoke from forest fires that blanketed the Indonesian islands of Kalimantan and Sumatra in late 1997 on adult health. To account for unobserved differences between haze and nonhaze areas, we compared changes in the health of individual respondents. Between 1993 and 1997, individuals who were exposed to haze experienced greater increases in difficulty with activities of daily living than did their counterparts in nonhaze areas. The results for respiratory and general health, although more complicated to interpret, suggest that haze had a negative impact on these dimensions of health.

    2010-05-01

    As a carbon-rich ecosystem, tropical peatland contributes significantly to terrestrial carbon storage and stability of the global carbon cycle. Vast areas of tropical peatland in SE Asia are degraded by the increasingly intensive scale of human activities, illustrated by high rates of deforestation, poor land-use management, selective illegal logging, and frequently repeated fires. Analysis of time-series satellite images performed in this study confirmed that fire regimes have dramatically changed in tropical peatlands over the last three decades (1973-2005). The study was conducted in the southern part of Central Kalimantan (Indonesian Borneo). We found that there was an evident increase in fire frequency and a decline in the fire return interval after implementation of the Mega Rice Project (1997-2005). Up until 1997, fires had affected a relatively small area, in total 23% of the study area, and were largely related to land clearance. This situation changed significantly during the last decade (1997-2005), when the widespread, intensive fires of 1997 affected a much larger area. Five years later, in 2002, extensive fires returned, affecting again 22% of the study area. Then, in 2004 and 2005, a further large area of peatland was on fire. Fire frequency analysis showed that during the period 1997-2005, around 45% of the study area was subject to multiple fires, with 37% burnt twice and 8% burnt three or more times. Near-annual occurrence of fire events reduces the rate and nature of vegetation regrowth. Hence, we observed a shift in the fire fuel type and amount over the period of investigation. After 1997, the fire fuel shifted from mainly peat swamp forest biomass towards non-woody biomass, dominated by regenerating vegetation, mainly ferns and a few trees. This secondary vegetation has been shown to be fire prone, although fire propagation is slower than in forest and restricted by both low fuel quality and load. Furthermore, we investigated the interaction

    The Sangsang deposit of the Eocene Senakin coal bed, Tanjung Formation, southeastern Kalimantan, Indonesia, contains 11 layers, which are thin ( 70%). These layers are characterized by their pelitic macroscopic texture. Examination of eight of the layers by scanning-electron microscopy, energy-dispersive X-ray, and X-ray diffraction analyses show that they are composed primarily of fairly well-crystallized kaolinite, much of which is vermicular. Accessory minerals include abundant Ti oxide, rare-earth element-rich Ca and A1 phosphates, quartz that luminescences in the blue color range, and euhedral to subhedral pyroxene, hornblende, zircon, and sanidine. Although this mineral suite is suggestive of volcanic ash-fall material, only the four pelitic layers in the middle of the bed are thought to be solely derived from volcanic ash-falls on the basis of diagnostic minerals, replaced glass shards, and lithostratigraphic relationships observed in core and outcrop. The three uppermost pelitic layers contain octahedral chromites, some quartz grains that luminesce in teh orange color range, and some quartz grains that contain two-phase fluid inclusions. These layers are interpreted to be derived from a combination of volcanic ash-fall material and hydrologic transport of volcaniclastic sediment. In contrast, the lowermost pelitic layer, which contains large, rounded FeMg-rich chromites, is thought to have been dominantly deposited by water. The source of the volcanic ash-fall material may have been middle Tertiary volcanism related to plate tectonic activity between Kalimantan and Sulawesi. The volcanic ash was deposited in sufficient amounts to be preserved as layers within the coal only in the northern portions of the Senakin region: the southern coal beds in the region do not contain pelitic layers. ?? 1993.

  17. Space Radar Image of Central Sumatra, Indonesia

    1994-01-01

    This is a radar image of the central part of the island of Sumatra in Indonesia that shows how the tropical rainforest typical of this country is being impacted by human activity. Native forest appears in green in this image, while prominent pink areas represent places where the native forest has been cleared. The large rectangular areas have been cleared for palm oil plantations. The bright pink zones are areas that have been cleared since 1989, while the dark pink zones are areas that were cleared before 1989. These radar data were processed as part of an effort to assist oil and gas companies working in the area to assess the environmental impact of both their drilling operations and the activities of the local population. Radar images are useful in these areas because heavy cloud cover and the persistent smoke and haze associated with deforestation have prevented usable visible-light imagery from being acquired since 1989. The dark shapes in the upper right (northeast) corner of the image are a chain of lakes in flat coastal marshes. This image was acquired in October 1994 by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the space shuttle Endeavour. Environmental changes can be easily documented by comparing this image with visible-light data that were acquired in previous years by the Landsat satellite. The image is centered at 0.9 degrees north latitude and 101.3 degrees east longitude. The area shown is 50 kilometers by 100 kilometers (31 miles by 62 miles). The colors in the image are assigned to different frequencies and polarizations of the radar as follows: red is L-band horizontally transmitted, horizontally received; green is L-band horizontally transmitted, vertically received; blue is L-band vertically transmitted, vertically received. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Mission to Planet Earth program.

  18. "Peer" educator initiatives for adolescent reproductive health projects in Indonesia.

    2004-05-01

    Since the ICPD in 1994, the Government of Indonesia has struggled with the challenge of providing sexual and reproductive health education to adolescents. Following an attempt at a family-centred approach, a pilot project was carried out in Central and East Java to train peer educators, coordinated by the National Family Planning Coordinating Board (BKKBN). A total of 80 peer educators (male/female teams) carried out small-group information sessions in ten different districts. Over 1,300 adolescents attended in all. Forty peer counsellors in 20 teams then carried out five outreach sessions each in their communities, attended by nearly 4,000 adults and adolescents. Educators chosen were older in age, knowledge level, authority and communication skills than adolescents, but were well accepted as mentors. Adolescents wanted to know how to deal with sexual relationships and feelings, unwanted pregnancy and STDs. With 42 million Indonesian adolescents needing information, the government cannot produce enough manuals to satisfy demand. New strategies are required to put information in the public domain, e.g. via the media. The approach described in this paper would probably be beyond the staffing and resource capacity of most districts in Indonesia. Nonetheless, it shows that there was great enthusiasm across a variety of communities for efforts to educate young people on protecting their reproductive health.

  19. Subduction Initiation in Eastern Indonesia

    NASA Astrophysics Data System (ADS)

    Hall, R.

    2014-12-01

    Subduction is often reported to be difficult to initiate, yet in the West Pacific and Eastern Indonesia there are many young subduction zones. Few theoretical or modelling studies consider such settings in which subduction commonly began close to boundaries between ocean crust and thickened crust of arc or continental origin. In Eastern Indonesia there are subduction zones at different stages of development. Some young examples such as the Banda Arc developed by propagation of an existing trench into a new area by tearing, probably along an ocean-continent boundary. This 'solves' the problem since the older subducted slab provides the driving force to drag down unsubducted ocean lithosphere. However, similar explanations cannot account for other subduction zones, such as North Sulawesi, nearby examples in which the subducted slab is not yet at 100 km depth, or troughs where subduction appears to be beginning. These examples show that subduction initiated at a point, such as a corner in an ocean basin, where there were very great differences in elevation between land and adjacent ocean floor. Depression of ocean crust by flow of arc/continent crust is associated with granitic magmatism and detachments within the upper crust. Once the oceanic corner reaches depths of c.100 km, eclogite formation may lead to slab pull that causes the new subduction zone to grow in both directions along strike; arc magmatism may or may not begin. The close relationship between subduction and extension in Eastern Indonesia links dramatic elevation of land, exhumation of deep crust, and spectacular subsidence of basins imaged by oil exploration seismic and multibeam data. Exhumed granites and high-grade metamorphic rocks at elevations up to 3 km, separated by Neogene alluvial sediments from carbonate reefs now at depths of 2 kilometres, imply vertical movements of several kilometres in a few million years. These observations raise the question of whether subduction is driving extension

    Dengue haemorrhagic fever (DHF) was first recognized in Indonesia in the cities of Jakarta and Surabaya in 1968, 15 years after its recognition in the Philippines. During the 1968 outbreak, a total of 58 clinical cases with 24 deaths were reported. The number of reported cases since then has increased sharply, with the highest number of cases recorded in the years 1973 (10, 189 cases), 1983 (13,668 cases), and 1985 (13,588 cases). Outbreaks of the disease have spread to involve most of the major urban areas, as well as some of the rural areas. In 1985, the disease had spread to 26 of 27 Provinces and 160 of 300 regencies or municipalities. At present, the disease is endemic in many large cities and small towns. Interestingly, DHF has not been reported in some cities, even though dengue virus transmission rates in those cities are high. The epidemic pattern of DHF for the country as a whole has become irregular. Since 1982, the intensity and spread of DHF has created an increasing public health problem in Indonesia, particularly in Java where 60% of the total population of the country resides. Java contributed about 71% of all cases occurring in the country in 1982, 84% in 1983, and 91% in 1984. The peak monthly incidence of DHF was frequently reported during October through April, months which coincide with the rainy season. The morbidity rate for Indonesia, estimated from reported cases over five years (1981-1985), ranged between 3.39 to 8.65 per 100,000 population.

  5. Women and tobacco in Indonesia

    Barraclough, S.

    1999-01-01

    OBJECTIVES—To present a broad exploration of the relationship of women and tobacco in Indonesia and to describe action on tobacco and health specific to women taken by government and non-government agencies.
DATA SOURCES—Published and unpublished prevalence surveys, official documents, vernacular newspapers, secondary sources, unstructured interviews, and personal observations.
STUDY SELECTION—Data on smoking prevalence among women was primarily sought from official household surveys but several smaller scale local surveys were also examined. The only representative national household data on smoking prevalence from 1995 suggested a national prevalence for occasional and regular smoking of 2.6% for women aged 20 years or older. Smaller, local level surveys had reported rates varying from 4% for junior high school girls, and 2.9% for women undergraduates at a provincial university, to 6.4% of women in a representative sample in Jakarta. Claims that the incidence of female smoking is increasing cannot be confirmed due to an absence of comparable national longitudinal data.
CONCLUSION—Although Indonesian women are conspicuous in growing and processing tobacco, their rates of smoking are low in comparison with their male compatriots and internationally. Anecdotal evidence suggests that their disinclination to smoke is commonly attributed to cultural values, which stigmatise women smokers as morally flawed, while at the same time sanctioning smoking by men. Although there is little evidence of tobacco advertising directly targeting women, Indonesian health activists interviewed by the author felt that women are increasingly taking up smoking due to a weakening of stigma and to Western cultural influences. Cultural factors in the low rates of smoking among Indonesian women deserve closer investigation as they have proved to be a major source of health protection, albeit within a stigmatising context. More also needs to be known about the dynamics of

The need for family planning on the outer Indonesian islands is not as great, but programs are being set under way. These programs are the beginning of an attempt to alleviate problems that could be encountered if Indonesia's population growth continues unchecked.

    Approximately 240 million people are chronically infected with hepatitis B virus (HBV), 75% of whom reside in Asia. Approximately 600000 of infected patients die each year due to HBV-related diseases or hepatocellular carcinoma (HCC). The endemicity of hepatitis surface antigen in Indonesia is intermediate to high with a geographical difference. The risk of HBV infection is high in hemodialysis (HD) patients, men having sex with men, and health care workers. Occult HBV infection has been detected in various groups such as blood donors, HD patients, and HIV-infected individuals and children. The most common HBV subgenotype in Indonesia is B3 followed by C1. Various novel subgenotypes of HBV have been identified throughout Indonesia, with the novel HBV subgenotypes C6-C16 and D6 being successfully isolated. Although a number of HBV subgenotypes have been discovered in Indonesia, genotype-related pathogenicity has not yet been elucidated in detail. Therefore, genotype-related differences in the prognosis of liver disease and their effects on treatments need to be determined. A previous study conducted in Indonesia revealed that hepatic steatosis was associated with disease progression. Pre-S2 mutations and mutations at C1638T and T1753V in HBV/B3 have been associated with advanced liver diseases including HCC. However, drug resistance to lamivudine, which is prominent in Indonesia, remains obscure. Although the number of studies on HBV in Indonesia has been increasing, adequate databases on HBV infection are limited.

  11. Theft of electricity in Indonesia

    Priatna, Dedy Supriadi

    In 1996, among 196 million Indonesian people, only 47.6% had access to electricity; 45.4% in rural areas and 51.5% in urban. 64% of population lived in 61,975 villages, and electric power was supplied to 69% of villages. The government has set a goal to achieve nearly universal services by the year 2014. The government can use existing installed capacity of PLN's system more efficiently. Theft of electricity, which currently constitutes a large share of PLN's losses, should be reduced. The potential of the private sector including captive power and local communities, to participate in electric power generation can also be utilized. The large interest that has been shown by the private sector might be followed by making electric power provision profitable and therefore attractive for the private sector. PLN profits, that in 1996 were only 5.22% instead of the 8% recommended by the World Bank as the best practice for Indonesia, have to be increased by improving their performance levels. The government should also seek solutions for the extremely poor households who will never be able to afford both connection charges and a monthly bill. In 1996 the extremely poor households included 5,251,788 households, constituting 12.1% of the total Indonesian households. Only 1.2% of these households had access to electricity. The objective of this study is to seek the policies that can be implemented in Indonesia that will make it possible to generate and deliver electricity profitably, and reduce theft while providing nearly universal services. For this purpose, the options that are proposed in this study are reducing theft of electricity; something like the CAMPFIRE that has successfully reduced poaching of elephants in Africa: that is, consumer-owned systems, both partially (distribution facilities) and completely (generation and distribution facilities); performance-based regulation (PBR); and solutions for supplying the extremely poor based on the minimum subsidies from the

    This Indonesian study evaluates associations between near-miss status/death with maternal demographic, health care characteristics, and obstetrical complications, comparing results using retrospective and prospective data. The main outcome measures were obstetric conditions and socio-economic factors to predict near-miss/death. We abstracted all obstetric admissions (1,358 retrospective and 1,240 prospective) from two district hospitals in East Java, Indonesia between 4/1/2009 and 5/15/2010. Prospective data added socio-economic status, access to care and referral patterns. Reduced logistic models were constructed, and multivariate analyses used to assess association of risk variables to outcome. Using multivariate analysis, variables associated with risk of near-miss/death include postpartum hemorrhage (retrospective AOR 5.41, 95 % CI 2.64-11.08; prospective AOR 10.45, 95 % CI 5.59-19.52) and severe preeclampsia/eclampsia (retrospective AOR 1.94, 95 % CI 1.05-3.57; prospective AOR 3.26, 95 % CI 1.79-5.94). Associations with near-miss/death were seen for antepartum hemorrhage in retrospective data (AOR 9.34, 95 % CI 4.34-20.13), and prospectively for poverty (AOR 2.17, 95 % CI 1.33-3.54) and delivering outside the hospital (AOR 2.04, 95 % CI 1.08-3.82). Postpartum hemorrhage and severe preeclampsia/eclampsia are leading causes of near-miss/death in Indonesia. Poverty and delivery outside the hospital are significant risk factors. Prompt recognition of complications, timely referrals, standardized care protocols, prompt hospital triage, and structured provider education may reduce obstetric mortality and morbidity. Retrospective data were reliable, but prospective data provided valuable information about barriers to care and referral patterns.

    Background Plasmodium vivax imposes substantial morbidity and mortality burdens in endemic zones. Detailed understanding of the contemporary spatial distribution of this parasite is needed to combat it. We used model based geostatistics (MBG) techniques to generate a contemporary map of risk of Plasmodium vivax malaria in Indonesia in 2010. Methods Plasmodium vivax Annual Parasite Incidence data (2006–2008) and temperature masks were used to map P. vivax transmission limits. A total of 4,658 community surveys of P. vivax parasite rate (PvPR) were identified (1985–2010) for mapping quantitative estimates of contemporary endemicity within those limits. After error-checking a total of 4,457 points were included into a national database of age-standardized 1–99 year old PvPR data. A Bayesian MBG procedure created a predicted PvPR1–99 endemicity surface with uncertainty estimates. Population at risk estimates were derived with reference to a 2010 human population surface. Results We estimated 129.6 million people in Indonesia lived at risk of P. vivax transmission in 2010. Among these, 79.3% inhabited unstable transmission areas and 20.7% resided in stable transmission areas. In western Indonesia, the predicted P. vivax prevalence was uniformly low. Over 70% of the population at risk in this region lived on Java and Bali islands, where little malaria transmission occurs. High predicted prevalence areas were observed in the Lesser Sundas, Maluku and Papua. In general, prediction uncertainty was relatively low in the west and high in the east. Conclusion Most Indonesians living with endemic P. vivax experience relatively low risk of infection. However, blood surveys for this parasite are likely relatively insensitive and certainly do not detect the dormant liver stage reservoir of infection. The prospects for P. vivax elimination would be improved with deeper understanding of glucose-6-phosphate dehydrogenase deficiency (G6PDd) distribution, anti-relapse therapy

    Plague in man occurred from 1968 to 1970 in mountain villages of the Boyolali Regency in Central Java. Infected fleas, infected rats, and seropositive rats were collected in villages with human plague cases. Subsequent isolations of Yersinia pestis and seropositive rodents, detected during investigations of rodent plague undertaken by the Government of Indonesia and the WHO, attested to the persistence of plague in the region from 1972 to 1974. Since 1968, the incidence of both rodent and human plague has been greatest from December to May at elevations over 1000 m. Isolations of Y. pestis were obtained from the fleas Xenopsylla cheopis and Stivalius cognatus and the rats Rattus rattus diardii and R. exulans ephippium. The major risk to man has been fleas infected with Y. pestis of unique electrophoretic phenotype. Infected fleas were collected most often in houses. Introduced in 1920, rodent plague had persisted in the Boyolali Regency for at least 54 years. The recent data support specific requirements for continued plague surveillance.

    The volcanic rock is seldom considered as good reservoir rocks. However, in Indonesia there is a volcanic layer called the Jatibarang Formation in Jatibarang Field, West Java, that has proven to be a producer of oil and gas of adequate amount. The lateral development of this rock extent along the whole of the basin, about 400 km over a Tertiary block-faulting system of the North West Java Basin. It is estimated that the volume of the spread is about 2360 km[sup 3]. Beside from the primary volcanic rock, the developing reservoir rock could also resulted from rework of massive volcanics or agglomerate, and other volcanic product resedimented as clastic deposits. The hydrocarbon is sourced from the younger Talang Aker Formation that is in direct contact with the reservoir rock. It migrated through the faults. Present cumulative production has reached 1.2 BBC and 2.7 TCFG, while speculative reserve is estimated at 4.0 BBO and 3 TCFG. Regionally, the volcanic rock of the Jatibarang Formation where the hydrocarbon is found is the result of eruptions along the magmatic trend during Late Cretaceous. In North West Java Basin, the trapping system includes both the structural and stratigraphic traps. Reservoir analysis yields pororsity values of around 16-25% and permeability of around 10 Darcies. It is concluded that there are good opportunities still left for hydrocarbon exploration in volcanic rocks. The study is discussed in detail, supported by data from cores and laboratories.

However, in Indonesia there is a volcanic layer called the Jatibarang Formation in Jatibarang Field, West Java, that has proven to be a producer of oil and gas of adequate amount. The lateral development of this rock extent along the whole of the basin, about 400 km over a Tertiary block-faulting system of the North West Java Basin. It is estimated that the volume of the spread is about 2360 km{sup 3}. Beside from the primary volcanic rock, the developing reservoir rock could also resulted from rework of massive volcanics or agglomerate, and other volcanic product resedimented as clastic deposits. The hydrocarbon is sourced from the younger Talang Aker Formation that is in direct contact with the reservoir rock. It migrated through the faults. Present cumulative production has reached 1.2 BBC and 2.7 TCFG, while speculative reserve is estimated at 4.0 BBO and 3 TCFG. Regionally, the volcanic rock of the Jatibarang Formation where the hydrocarbon is found is the result of eruptions along the magmatic trend during Late Cretaceous. In North West Java Basin, the trapping system includes both the structural and stratigraphic traps. Reservoir analysis yields pororsity values of around 16-25% and permeability of around 10 Darcies. It is concluded that there are good opportunities still left for hydrocarbon exploration in volcanic rocks. The study is discussed in detail, supported by data from cores and laboratories.

    Current estimates of carbon (C) storage in peatland systems worldwide indicate that tropical peatlands comprise about 15% of the global peat carbon pool. Such estimates are uncertain due to data gaps regarding organic peat soil thickness, volume and C content. We combined a set of indirect geophysical methods (ground-penetrating radar, GPR, and electrical resistivity imaging, ERI) with direct observations using core sampling and C analysis to determine how geophysical imaging may enhance traditional coring methods for estimating peat thickness and C storage in a tropical peatland system in West Kalimantan, Indonesia. Both GPR and ERI methods demonstrated their capability to estimate peat thickness in tropical peat soils at a spatial resolution not feasible with traditional coring methods. GPR is able to capture peat thickness variability at centimeter-scale vertical resolution, although peat thickness determination was difficult for peat columns exceeding 5 m in the areas studied, due to signal attenuation associated with thick clay-rich transitional horizons at the peat-mineral soil interface. ERI methods were more successful for imaging deeper peatlands with thick organomineral layers between peat and underlying mineral soil. Results obtained using GPR methods indicate less than 3% variation in peat thickness (when compared to coring methods) over low peat-mineral soil interface gradients (i.e., below 0.02°) and show substantial impacts in C storage estimates (i.e., up to 37 MgC ha-1 even for transects showing a difference between GPR and coring estimates of 0.07 m in average peat thickness). The geophysical data also provide information on peat matrix attributes such as thickness of organomineral horizons between peat and underlying substrate, the presence of buried wood, buttressed trees or tip-up pools and soil type. The use of GPR and ERI methods to image peat profiles at high resolution can be used to further constrain quantification of peat C pools and

  20. Japan, Indonesia to investigate condom plant feasibility.

    The Japanese government has begun investigations on the possibility of constructing a condom manufacturing plant in Indonesia in response to a request by the Indonesian government. Indonesia, which hopes to reduce its birthrate as of 1971 by 1/2 by 1990, asked for Japanese assistance in building a condom plant based on the expectation that demand for this contraceptive method, although quite low at present, will increase rapidly in the near future with stepped-up motivation campaigns. As a 1st step in the investigation, the Japan International Cooperation Agency (JICA) sent a study team of family planning experts headed by Family Planning Federation of Japan Chairman Dr. Hidebumi Kubo and including JOICFP International Division Director MR. Tameyoshi Katagiri to Indonesia from March 15-24. During its visit, the JICA team held discussions with representatives of BKKBN (the National Family Planning Coordinating Board) including its Chairman and Minister of Health Dr. Suwardjono and reached agreement on the scope and schedule of work toward determining the feasibility of building and operating a condom plant in Indonesia. In defining the scope of work and the schedule, the JICA team and the BKKBN representatives decided on specific issues to be investigated in the feasibility study to be carried out by JICA and scheduled to be completed by the end of October of this year. To be included in the feasibility study are: estimation of future domestic demand for condoms, examination of the domestic supply of latex capacity, chemicals and packaging materials, and collection of information on infrastructure relating to water, energy, transportation, etc. Actual data collection for the study is expected to begin in late May or early June. Dr. Kubo and Mr. Katagiri, upon returning to Japan, reported great enthusiasm for the project in Indonesia and expressed the hope that the plant construction will be feasible so that the country's family planning program can be given a boost

    Indonesia depends heavily on revenues from the export of LNG and oil, the availability of which appears to be decreasing. It is therefore making a strong effort to accelerate development of a domestic natural gas industry. A high priority has been given to the conversion of power plants and city gas systems, including local industries and commercial facilities, from liquid fuels to natural gas. This will release more oil for export, help to meet the objectives of Repelita V, and provide substantial environmental benefits. The World Bank recently provided loans to the Indonesian Government for two projects that are aimed at substituting natural gas for oil and manufactured gas in domestic markets. One project involves expansion of the gas distribution systems of Indonesia's natural gas utility (PGN) in three cities: Jakarta and Bogor in Java, and Medan in Sumatra. The project also includes training programs for PGN staff and an energy pricing policy study to be carried out by Indonesia's Ministry of Mines and Energy. The second project involves expansion of the supply of natural gas for Surabaya and twelve other towns in its vicinity in East Java, and further expansion of Medan's supply system. Technical assistance will be provided to enhance the skills ofPGN and the Ministry of Mines and Energy, and a Gas Technology Unit similar to the Institute of Gas Technology will be established at Indonesia's Research and Development Center for Oil and Gas (LEMIGAS) in Jakarta. 14 refs., 3 figs., 11 tabs.

    1997-01-01

    These images of the Pacific Ocean near Indonesia were produced using sea surface height measurements taken by the U.S.-French TOPEX/Poseidon satellite. The images show sea surface height relative to normal ocean conditions during December 1996 and August 1997. The difference in sea level between these months is tied to the movement of warm water away from Indonesia.

    In December (left image), red and white areas indicate the presence of warm, higher than average sea level around Indonesia. At this time, massive amounts of warm water were detected around Indonesia by the TOPEX/Poseidon satellite. The warm, wet air from this water fed the normally heavy rainfall in this region.

    By August 1997 (right image), sea level had dropped well below average as shown by purple areas (sea level at least 18 centimeters (7 inches) below normal). The warm water had shifted east towards the west coast of North and South America, taking the rains with it.

    The white and red areas indicate patterns of unusually high heat storage; in the white areas, the sea surface is between 14 and 32 centimeters (6 to 13 inches) above normal; in the red areas, it's about 10 centimeters (4 inches) above normal.

    The movement of warm water away from the western Pacific is tied to the weather-disrupting phenomenon known as El Nino. The departure of the large mass of warm water that is normally located near Indonesia has affected where rain clouds form, altered the typical atmospheric patterns and brought devastating drought to Indonesia. The El Nino phenomenon is thought to be triggered when the steady westward blowing trade winds weaken and even reverse direction.

    Using these global data, limited regional measurements from buoys and ships, and a forecasting model of the ocean-atmosphere system, the National Centers for Environmental Prediction (NCEP) of the National Oceanic and Atmospheric Administration (NOAA) has issued an advisory indicating the presence of the early indications of El

    The Centre for Development and Population Activities (CEDPA) and the Indonesian Midwives Association (IBI) have developed a two-phase training program regarding gender issues for the association's midwives. The first phase focuses on the leadership, management, and advocacy skills necessary to articulate program needs and to take part in making decisions regarding family planning and reproductive health. The second phase concerns the integration of gender into project design. Proposals developed by the midwives include the following: 1) to improve counseling services for women in a district where 70% of the women using contraception do not decide for themselves which methods to use; 2) to reduce maternal mortality in a district where it has increased by 20% and where women have died while waiting for husbands or fathers-in-law to make the decision to bring them to hospitals; 3) to develop gender-sensitive materials concerning HIV/AIDS; and 4) to expand gender training to all levels of IBI, to provide follow-up technical support, and to integrate gender into the mission statement of the organization. Dr. Nafsiah Mboi (member of Parliament and vice chair of the Global Commission on Women's Health), Dr. Widyastuti Wibisana (director of community participation in the Ministry of Health), Dr. Kokila Vaidya (WHO Medical Officer), Carla Bianpoen (gender specialist with the World Bank), and Titi Sumbung (director of the Melati Foundation) helped to develop and to conduct the program.

  5. Population and food problems in Indonesia.

    Rusli, S

    1979-06-01

    This discussion examines the relationship between population growth and food problems in Indonesia and their connection with the total food production requirement particularly of staples or basic foods in the country. In 1976 Indonesia's population numbered about 130 million. The uneven distribution of population by regions is 1 of the outstanding features of Indonesia's demographic situation. The estimates of mortality levels for the period 1961-1971 mostly refer to life expectancies at birth over 40 years. Using 1971 census data Nicoli and Mamas estimated that life expectancy at birth in Indonesia during 1960-1970 was around 45-46 years. Heligman, considering the situation of economics, food, health facilities, and so forth questioned that there was a considerable improvement in mortality levels during the 1960s compared with that in the 1950s. In the 1960-1970 period the infant mortality rate was estimated at about 143/1000 births. The crude birthrate was around 43-44/1000 for the whole of Indonesia over the 1970-1971 period. Currently, Indonesia is implementing a family planning program which the government adopted in 1968. The recent estimate of crude birthrate is about 38/1000. Indonesia's projected population in 1990-1991 ranges from 180-202 million; its range will be from 209-272 million around the year 2000. A wide range of foods is produced in Indonesia, but some are more prominent than others. These are the basic foods such as rice, corn (maize), cassava. The availability of food production per head per year in Indonesia is at this time relatively similar to what it was in the pre World War 2 period, although rice production per head per year has increased in recent years due to wet land extensification and the involvement of Indonesia in the green revolution. Non-rice basic food available per head continues to seem far below that in the pre World War 2 period. Population increase is in part responsible for the deteriorating non-rice basic food available

    Indonesia contains 27 active volcanoes passing the West through the East part. Therefore, Indonesia is the most hazard front due to the volcanic activities. To obtain the new precursory signals leading to the eruptions, we applied remote sensing technique to observe ground surface change series at the summit of Sinabung and Kelud volcanoes. Sinabung volcano is located at Karo Region, North Sumatra Province. This volcano is a strato volcano type which is re-activated in August 2010. The eruption continues to the later years by ejecting volcanic products such as lava, pyroclastic flow, and ash fall deposits. This study is targeted to observe ground surface change series at the summit of Sinabung volcano since 2007 to 2011. In addition, we also compared the summit ground surface changes after the eruptions of Kelud volcano in 2007. Kelud volcano is also strato volcano type which is located at East Java, Indonesia. The Synthetic Aperture Radar (SAR) remotely sensed technology makes possible to observe rapidly a wide ground surface changes related to ground surface roughness. Detection series were performed by extracting the backscattering intensity of the Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard the Advanced Land Observing Satellite (ALOS). The intensity values were then calculated using a Normalized Radar Cross-Section (NRCS). Based on surface roughness criterion at the summit of Sinabung volcano, we could observe the ground surface changes prior to the early eruption in August 2010. The continuous increment of NRCS values showed clearly at window size 3×3 pixel of the summit of Sinabung volcano. The same phenomenon was also detected at the summit of Kelud volcano after the 2007 eruptions. The detected ground surface changes were validated using optical Landsat-8, backscattering intensity ratio for volcanic products detection, and radial component of a tilt-meter data.

    Road networks in Indonesia consist of 446,000 km of national, provincial and local roads as well as toll highways. Indonesia is one of countries that exposed to various natural hazards, such as earthquakes, floods, landslides, etc. Within the Indonesian archipelago, several global tectonic plates interact, such as the Indo-Australian, Pacific, Eurasian, resulting in a complex geological setting, characterized by the existence of seismically active faults and subduction zones and a chain of more than one hundred active volcanoes. Roads in Indonesia are vital infrastructure needed for people and goods movement, thus supporting community life and economic activities, including promoting regional economic development. Road damages and losses due to earthquakes have not been studied widely, whereas road disruption caused enormous economic damage. The aim of this research is to develop a method to analyse risk caused by seismic hazard to roads. The seismic risk level of road segment is defined using an earthquake risk index, adopting the method of Earthquake Disaster Risk Index model developed by Davidson (1997). Using this method, road segments' risk level can be defined and compared, and road risk map can be developed as a tool for prioritizing risk mitigation programs for road networks in Indonesia.

    Although over 400 languages are spoken in Indonesia, by 1986 60% of the population had some competence in the Indonesian national language, a substantial increase over 1971. Bahasa Indonesia was declared the state language in the 1945 constitution, and reformed spelling was agreed in 1972. It is the sole medium of instruction, except in the first three grades of elementary school in nine regions, where vernaculars may be used transitionally. Thereafter vernaculars are taught as school subjects. Bilingualism, and even multilingualism in Indonesian and one or more vernaculars and/or foreign languages is increasing, and despite the use of Indonesian for official documentary purposes at all levels it does not appear that vernaculars are dying out, although their spheres of use are restricted. Bahasa Indonesia fulfils the four functions: cognitive, instrumental, integrative and cultural, while vernaculars are only integrative and cultural. The curriculum of Indonesian, established centrally, is pragmatic or communicative. It is expressed in a standard syllabus for course books. This approach equally applies to foreign languages, which are introduced at secondary level, although here receptive reading is given more weight than productive skills. A full description of the syllabus organization of the various languages is given. Nonformal language learning also takes place, in the national basic education and literacy programme, which teaches Bahasa Indonesia, and in vocational courses in foreign languages for commerce.

    The ongoing eruption of the Lusi mud volcano (East Java, Indonesia), which began on May 29, 2006, has displaced more than 60,000 people and cost billions of US dollars in economic losses. We measured ground deformation near Lusi using interferometric processing of 46 L-band synthetic aperture radar images acquired by the ALOS satellite between 2006 and 2011. We analyzed the ground deformation using principal component analysis (PCA) and found that the dominant spatial mode of ground deformation is decreasing exponentially in amplitude with a timescale of 2.1+0.5-0.3 years, implying that the eruption rate will decrease by an order of magnitude, to less than 1000 m3/day, by 2016±1 year, much sooner than previously anticipated (Istadi et al. 2009, Davies et al. 2011, Rudolph et al. 2011). We also modeled the observed ground deformation to determine the mud chamber radius and pressure time history subject to geologic constraints on depth and thickness. The co-evolution of the mud chamber geometry and pressure suggest progressive mobilization of mud during the eruption, a process analogous to one that may occur in large explosive silicic volcanic eruptions.

    2001-12-01

    A policy of allowing public hospitals to provide some better quality, higher priced hospital beds for those able to pay was introduced as government policy in Indonesia after 1993. A study was conducted in 1998 in three public hospitals in East Java to investigate if the policy objective of cost-recovery was being achieved. Hospital revenue from these commercial beds was less than both the recurrent and total costs of providing them in all three hospitals, but exceeded recurrent costs minus staff salaries in two hospitals. One reason for the low cost-recovery ratios was that between 55% and 66% of the revenue was used as staff incentives, mostly to doctors. This was more than the maximum of 40% stipulated in the policy. The high proportions of total revenue going to staff were a result of hospital management having set bed fees too low. The policy may be contributing to the retention of doctors within public sector employment; however, it is not achieving its stated objective, especially over the longer term where full recovery of salaries and investment costs needs to be considered. Public hospitals that wish to invest in commercial beds need effective management and accounting systems so as to be able to monitor and control costs and set fees at levels that recoup the costs incurred. Further research is required to determine if this form of public-private mix has negative effects on equity and access for poorer patients. PMID:11772986

    In 1977 and 1978 selected in-patients at the Tegalyoso Hospital, Klaten, Indonesia who had recent onsets of acute fever were serologically studied for evidence for alphavirus and flavivirus infections. A brief clinical history was taken and a check list of signs and symptoms was completed on admission. Acute and convalescent phase sera from 30 patients who showed evidence that a flavivirus had caused their illnesses were tested for neutralizing antibodies to several flaviviruses which occur in South-east Asia. Paired sera from seven patients demonstrated a fourfold rise in antibody titre from acute to convalescent phase. The most common clinical manifestations observed in this series of patients included high fever, malaise, stomach ache, dizziness and anorexia. None of the seven patients had headache or rash despite the fact that headache and rash had been associated with two of the three previously studied. The onsets of illness clustered toward the end of the rainy season when populations of Aedes aegypti, a probable vector in Malaysia, were most abundant.

    As a result of the stabilization of oil prices in 1987 following their collapse in 1986, the rate of slowdown in Far East exploration activities began to ease. Seismic acquisition increased slightly, and the fall in exploratory drilling was less dramatic in 1987 than in 1986. No major discoveries were reported during 1987, although small-to-medium-size oil and gas discoveries added to the potential reserves of Bangladesh, India, Indonesia, Japan, People's Republic of China, Pakistan, Republic of China, and Thailand. Development drilling continued to rise by a modest amount. Far East oil and condensate production decreased in 1987 by just over 1% to 5.37 million b/d, whereas gas output rose to 11.7 bcf/day. New acreage awards were significantly higher in 1987 than in 1986, particularly in some of the region's key producing countries. 16 figs., 11 tabs.

The community oriented primary health care program has established new health centers and significantly increased health manpower. To enhance the role of women in socioeconomic development, the family planning program has introduced income-generating schemes in rural areas throughout the country. A network of information services on population and family planning has been established, and the government is working on the Indonesian Population Plan of Action to provide a longterm perspective on integrating population and development.

    The emphasis of Indonesia's experiment with village distribution of contraceptives, begun in 1974, is on maintenance rather than initiation of oral contraceptive use. As part of the experiment, it was decided to make resupplies available without charge outside the clinics on Java and Bali experimentally. The effort operated on the principles of avoiding standardization and focusing on resupply. In the province of West Java, resupply depots were established in the homes of acceptors whoowere also known village leaders. Each month the depot holders received a resupply, had their record-keeping reviewed, and were advised on how to deal with complaints. Presently, there are about 1600 village distribution centers with each of these units serving several subunits of a village. Effective village distribution efforts have also been established in Central Java and East Java. A unique feature of the East Java program is a lottery created to sustain the interest of those already in the program as well as to attract new acceptors. The Bali program is different from those of East Java in that most acceptors are IUD users. In this program emphasis is on recruiting new acceptors and maintaining those already in the program, and motivational effort is directed to the male. Village distribution effort data in Indonesia suggest that as the number of village distribution outlets increases, the proportion of married women of reproductive age who use contraception also increases. In addition to the government supported family planning program, there is now a combined effort supported by the Indonesian government and Aid to International Development to achieve acceptance of the condom and increased involvement of men in family planning.

    Knowledge of live animal movement through markets and from farm-to-farm is needed to inform strategies for control of trans-boundary animal diseases (TADs) in south-east Asia, particularly due to consumer preference for fresh meat. In eastern Indonesia a TAD of principal interest for control is classical swine fever (CSF) due to its impacts on smallholder farmers. Pig movement is considered a contributor to failure of current CSF control efforts but pig movement patterns are not well understood. This study investigated movement of live pigs in West Timor, Flores and Sumba islands during 2009-2010, with the aim of informing CSF control policies for Nusa Tenggara Timor province. A market survey of 292 pig sellers and 281 pig buyers across nine live pig markets and a farmer survey across 18 villages with 289 smallholder farmers were conducted and information collected on pig movements. The data obtained was used for social network analysis (SNA) on formal (via a market) and informal (village-to-village) movements using information on trading practices, source and destination locations, and the number of pigs being moved. Both inter- and intra-island movements were identified, however inter-island movement was only observed between Flores and Sumba islands. West Timor and Sumba had highly connected networks where large numbers of villages were directly and indirectly linked through pig movement. Further for West Timor, both formal and informal pig movements linked the capital Kupang, on the eastern end of the island to the western districts bordering East Timor connecting all five districts and demonstrating that informal movement transports pigs over distances similar to formal movement on this island. Sumba had a higher potential for pigs to move to a greater number of sequential locations across the entire island. Flores was found to have a more fragmented network, with pig movements concentrated in its eastern or western regions, influenced by terrain. Markets were

    The influx of refugees from Vietnam had created some consequences especially in transmission of certain communicable diseases. During several months of their first arrival, most of illness (90%) were caused by upper respiratory tract infections, skin diseases and diarrhoeal diseases. Several efforts and measures had been done by the Government of Indonesia in collaboration with several agencies i.e. P3V, PMI, UNHCR, W.VI, etc. As a result of the activities, a reduction of diarrhoeal diseases, has been observed. There was no cholera or typhoid cases detected through routine surveillance activities or by special survey. If we examine the morbidity and mortality pattern of refugees or we are comparing with Indonesian figures, it can be concluded that diarrhoeal diseases is not a significant health problem among refugees in Indonesia.

    We present the first national probabilistic tsunami hazard assessment (PTHA) for Indonesia. This assessment considers tsunami generated from near-field earthquakes sources around Indonesia as well as regional and far-field sources, to define the tsunami hazard at the coastline. The PTHA methodology is based on the established stochastic event-based approach to probabilistic seismic hazard assessment (PSHA) and has been adapted for tsunami. The earthquake source information is primarily based on the recent Indonesian National Seismic Hazard Map and included a consensus-workshop with Indonesia's leading tsunami and earthquake scientists to finalize the seismic source models and logic trees to include epistemic uncertainty. Results are presented in the form of tsunami hazard maps showing the expected tsunami height at the coast for a given return period, and also as tsunami probability maps, showing the probability of exceeding a tsunami height of 0.5m and 3.0m at the coast. These heights define the thresholds for different tsunami warning levels in the Indonesian Tsunami Early Warning System (Ina-TEWS). The results show that for short return periods (100 years) the highest tsunami hazard is the west coast of Sumatra, the islands of Nias and Mentawai. For longer return periods (>500 years), the tsunami hazard in Eastern Indonesia (north Papua, north Sulawesi) is nearly as high as that along the Sunda Arc. A sensitivity analysis of input parameters is conducted by sampling branches of the logic tree using a monte-carlo approach to constrain the relative importance of each input parameter. The results from this assessment can be used to underpin evidence-based decision making by disaster managers to prioritize tsunami mitigation, such as developing detailed inundation simulations for evacuation planning.

  17. CO₂ efflux from shrimp ponds in Indonesia.

    2013-01-01

    The conversion of mangrove forest to aquaculture ponds has been increasing in recent decades. One of major concerns of this habitat loss is the release of stored 'blue' carbon from mangrove soils to the atmosphere. In this study, we assessed carbon dioxide (CO₂) efflux from soil in intensive shrimp ponds in Bali, Indonesia. We measured CO₂ efflux from the floors and walls of shrimp ponds. Rates of CO₂ efflux within shrimp ponds were 4.37 kg CO₂ m⁻² y⁻¹ from the walls and 1.60 kg CO₂ m⁻² y⁻¹ from the floors. Combining our findings with published data of aquaculture land use in Indonesia, we estimated that shrimp ponds in this region result in CO₂ emissions to the atmosphere between 5.76 and 13.95 Tg y⁻¹. The results indicate that conversion of mangrove forests to aquaculture ponds contributes to greenhouse gas emissions that are comparable to peat forest conversion to other land uses in Indonesia. Higher magnitudes of CO₂ emission may be released to atmosphere where ponds are constructed in newly cleared mangrove forests. This study indicates the need for incentives that can meet the target of aquaculture industry without expanding the converted mangrove areas, which will lead to increased CO₂ released to atmosphere.

    Indonesia has set an ambitious target of reducing its maternal mortality rate to 125 maternal deaths per 100,000 live births by the year 2010. This poses formidable challenges in a geographically diverse country where the majority of births occur at home. One option for the Indonesian government in order to reduce its maternal mortality would be to increase rates of skilled assistance for home deliveries. In order to design appropriate policies to achieve this, it is imperative to understand the determinants of use of birth attendants by mothers delivering at home. We use the Andersen Behavioral Model as a theoretical framework to understand the determinants of the use of a trained provider, traditional birth attendant, or no trained assistance during home deliveries in Indonesia. The 1997 Indonesia Demographic and Health Survey (IDHS) was used, and data from the most recent home delivery was abstracted for analysis. Out of a total sample of 10,692 home deliveries, a majority (53%) used the services of a TBA, 40% had a doctor, nurse or midwife in attendance, and only 7% delivered with the help of family and/or friends. A multinomial logit model was used to predict determinants of use. Our results indicate that maternal education, religion, asset index quartile and number of antenatal visits are significant determinants among all choice sets.

    Sumedang Observatory (6.91°S, 107,84°E) was established in 1975 and is one of the solar observation facilities of the Space Science Center of Indonesian National Institute of Aeronautics and Space (LAPAN), located around 40 km, east part of Bandung City, West Java, Indonesia. Several instrumentations for solar and space observation such as optical telescopes, radio solar spectrograph, flux gate magnetometer, etc. are operated there, together with an ionosphere sounding system (ionosonde) that was set up later. In July 2014, a standard Callisto (Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory) spectrometer was installed at Sumedang Observatory for solar radio activity monitoring. Callisto has been developed in the framework of IHY2007 and ISWI, supported by UN and NASA. Callisto spectrometer has observation capability in the frequency range of 45-870 MHz. The Callisto spectrometer receives signal by using a set of 21 elements log-periodic antenna, model CLP5130-1N, pointed to the Sun and equipped with a low noise pre-amplifier. With respect to the Radio Frequency Interferences (RFI) measurements, the Callisto spectrometer is operated individually in frequency ranges of 45-80 MHz and 180-450 MHz. Observation status and data flow are monitored in on-line from center office located in Bandung. The data was transferred to central database at FHNW (Fachhochschule Nordwestschweiz) server every 15 minutes to appear on e-Callisto network subsequently. A real time data transfer and data processing based on Python software also has been developed successfully to be used as an input for Space Weather Information and Forecasting Services (SWIFtS) provided by LAPAN. On 5th November 2014, Callisto spectrometer at Sumedang observed the first clear solar radio event, a solar radio burst type II corresponding to a coronal mass ejection (CME), indicated by a strong X-ray event of M7.9 that was informed on by Space Weather

  20. An optimal renewable energy mix for Indonesia

    2016-04-01

    Indonesia has experienced a constant increase of the use of petroleum and coal in the power sector, while the share of renewable sources has remained stable at 6% of the total energy production during the last decade. As its domestic energy demand undeniably continues to grow, Indonesia is committed to increase the production of renewable energy. Mainly to decrease its dependency on fossil fuel-based resources, and to decrease the anthropogenic emissions, the government of Indonesia has established a 23 percent target for renewable energy by 2025, along with a 100 percent electrification target by 2020 (the current rate is 80.4 percent). In that respect, Indonesia has abundant resources to meet these targets, but there is - inter alia - a lack of proper integrated planning, regulatory support, investment, distribution in remote areas of the Archipelago, and missing data to back the planning. To support the government of Indonesia in its sustainable energy system planning, a geographic explicit energy modeling approach is applied. This approach is based on the energy systems optimization model BeWhere, which identifies the optimal location of energy conversion sites based on the minimization of the costs of the supply chain. The model will incorporate the existing fossil fuel-based infrastructures, and evaluate the optimal costs, potentials and locations for the development of renewable energy technologies (i.e., wind, solar, hydro, biomass and geothermal based technologies), as well as the development of biomass co-firing in existing coal plants. With the help of the model, an optimally adapted renewable energy mix - vis-à-vis the competing fossil fuel based resources and applicable policies in order to promote the development of those renewable energy technologies - will be identified. The development of the optimal renewable energy technologies is carried out with special focus on nature protection and cultural heritage areas, where feedstock (e.g., biomass

    In developing countries, like Indonesia, apheresis is still a relative new procedure. Nowadays, therapeutic apheresis procedures are performed in the field of hematology and neurology, especially in the teaching hospitals in Indonesia. Therapeutic apheresis procedure, that is, leukocytapheresis, therapeutic plasma exchange (TPE), and thrombocytapheresis are already performed. In the period 2009-2013, 204 apheresis procedures in 137 patients to reduce the leukocytes, 72 TPE procedures in 17 patients, and 14 thrombocyte reductions were performed in the Sardjito hospital, Yogyakarta, Indonesia. In the future, to improve the therapeutic apheresis implementation, it is important to increase the insurance coverage and also should be considered to introduce the apheresis medicine into the curriculum of appropriate physician programs in Indonesia. Especially in Indonesia, a lot of efforts are still being needed to improve implementation of therapeutic apheresis.

    Indonesia's infant mortality rates are among the highest in South-East Asia, and there are substantial variations between its sub-national regions. This qualitative study aims to explore early mortality-related health service provision and gender inequity issues based on mothers' pregnancy, delivery and early-age survival experience in Ende district, Nusa Tenggara Timur province. Thirty-two mothers aged 18-45 years with at least one birth in the previous five years were interviewed in depth in May 2013. The results show most mothers have little knowledge about the danger signs for a child's illness. Mothers with early-age deaths generally did not know the cause of death. Very few mothers had received adequate information on maternal and child health during their antenatal and postnatal visits to the health facility. Some mothers expressed a preference for using a traditional birth attendant, because of their ready availability and the more extensive range of support services they provide, compared with local midwives. Unprofessional attitudes displayed by midwives were reported by several mothers. As elsewhere in Indonesia, the power of health decision-making lies with the husband. Policies aimed at elevating mothers' roles in health care decision-making are discussed as measures that would help to improve early-age survival outcomes. Widening the public health insurance distribution, especially among poorer mothers, and equalizing the geographical distribution of midwives and health facilities are recommended to tackle geographical inequities and to increase early-age survival in Ende district.

    The International Megaregional Project is a worldwide project involving the compilation and interpretation of long regional seismic lines which cross several basins with the same transect. The goal of the project is to synthesize the current geologic knowledge of the areas traversed and to identify new areas of exploration interest. The International Megaregional framework which has been established serves as a focus for the geologic efforts and seismic data compilation. This project was conducted with the cooperation of a consortium of multinational oil companies as well as Pertamina and CGG. Megaregional lines can provide new insights into: (1) what is and is not basement, (2) maturation history and migration pathways, (3) regional structure, and (4) regional stratigraphy. The lines can thereby lead to the development of new exploration concepts. The project is based on 4900 km, of state-of-the-art marine seismic data acquired in 1993. The poster session includes examples of several Megaregional lines from three areas in Eastern Indonesia and another area east of Natuna Island. Key geologic features imaged by the transacts include, subduction zones (lava Trench, Timor Trough) Island Arcs (Sumatra/Bali Arc), back arc basins (eg.. Bali Basin) and major wrench zones (Sorong Fault). The seismic expression of reef plays (Natuna Sea, Salawati Basin), deltaic plays (eg, Mahakam Delta), and other plays is well illustrated. These lines provide an unprecedented perspective on the petroleum setting of Eastern Indonesia.

    Site selection for modern astronomical observatory is based on various meteorological parameters to determine the quality of the sky above the corresponding sites. Recent study for Indonesian astronomical site selection has indicated that regions of East Nusa Tenggara have favorable meteorological conditions, mostly derived from clear sky fraction. As a further study of comparative site analysis, in this paper, we present an evaluation of aerosol distribution over Indonesia as an important parameter of site quality. The long-term availability of meteorological satellite data is obviously useful to obtain the general trends of the corresponding parameter. It is known that the presence of aerosol in the atmosphere can affect astronomical extinction and, therefore, may influence the quality of observational data. The aerosol data analyzed here are from satellite measurements of TOMS-EP, N7, and OMI-AURA of Level 3, from the period of 1978 to mid-2014. We select several locations in Indonesia and compare them to a candidate site in Timor, to obtain the variation of aerosol distribution over the regions of interest. This result is useful to compare with astronomical observations from site testing.

    There are so many definitions for ergonomics terms such as human factors, human factors engineering, human engineering, human factors psychology, engineering psychology, applied ergonomics, occupational ergonomics, industrial ergonomics and industrial engineering. The most inclusive terms are ergonomics and human factors. Both represent the study of work and the interaction between people and their work environmental systems. The main objective is especially fitting with the need to design, develop, implement and evaluate human-machine and environment systems that are productive, comfortable, safe and satisfying to use. The work of the ergonomists in Indonesia--most of them are academicians--have one thing in common, i.e. with the appropriate type of ergonomic approaches to interventions; there would be improvements in productivity, quality of working conditions, occupational safety and health (OSH), costs reduction, better environment, and increase in profits. So many researches, training, seminars and socialization about ergonomics and OSH have been done concerning micro-to-macro themes; but it seems that we are practically still running at the same place up to now. In facts, workers are still working using their traditional or obsolete methods in poor working conditions. Accidents are still happening inside and outside industry with the main root-cause being human "unsafe behavior" and errors. Industrial products cannot compete in the global market, and so many manufacturing industries collapsed or relocated to foreign countries. This paper discusses such a roadmap and review what we ergonomists in Indonesia have done and where we are going to? This review will be treated in the field of ergonomics and OSH to take care the future Indonesia challenges. Some of the challenges faced are care for the workers, care for the people, care for the quality and productivity of work, care for the new advanced technologies, care for the environment, and last but not least

    Probabilistic hazard assessments are a fundamental tool for assessing the threats posed by hazards to communities and are important for underpinning evidence-based decision-making regarding risk mitigation activities. Indonesia has been the focus of intense tsunami risk mitigation efforts following the 2004 Indian Ocean tsunami, but this has been largely concentrated on the Sunda Arc with little attention to other tsunami prone areas of the country such as eastern Indonesia. We present the first nationally consistent probabilistic tsunami hazard assessment (PTHA) for Indonesia. This assessment produces time-independent forecasts of tsunami hazards at the coast using data from tsunami generated by local, regional and distant earthquake sources. The methodology is based on the established monte carlo approach to probabilistic seismic hazard assessment (PSHA) and has been adapted to tsunami. We account for sources of epistemic and aleatory uncertainty in the analysis through the use of logic trees and sampling probability density functions. For short return periods (100 years) the highest tsunami hazard is the west coast of Sumatra, south coast of Java and the north coast of Papua. For longer return periods (500-2500 years), the tsunami hazard is highest along the Sunda Arc, reflecting the larger maximum magnitudes. The annual probability of experiencing a tsunami with a height of > 0.5 m at the coast is greater than 10% for Sumatra, Java, the Sunda islands (Bali, Lombok, Flores, Sumba) and north Papua. The annual probability of experiencing a tsunami with a height of > 3.0 m, which would cause significant inundation and fatalities, is 1-10% in Sumatra, Java, Bali, Lombok and north Papua, and 0.1-1% for north Sulawesi, Seram and Flores. The results of this national-scale hazard assessment provide evidence for disaster managers to prioritise regions for risk mitigation activities and/or more detailed hazard or risk assessment.

    After a review of the traditional society as found in Indonesia, the role of Islam in this changing, modernizing society, and changes which must be made by religious leaders to cope with development, which is bettering life for the people, are discussed. Centuries of oppressive colonial rule have kept many Indonesian Moslem village-families locked into a passive, subsistence way of life. A fatalistic mentality makes family and children together with performing the religious rituals the chief rewards of earthly life. With modernization many young people have left the villages hoping for economic opportunity. Instead they do not have technical skills and they find themselves without either the material advancements promised by modernization or the traditional dignity and pride which is found in the village family. Through centuries of distortion the position of Islam on the family, which is one of love and justice, became viewed as a system in which the traditional faith no longer meets modern situations and church leaders do not help matters by protesting and exhorting insteading of going back to basic truths and showing the way to a better life. The 1st field which demands attention is the attitude toward human reproduction. Leaders should find verses like Al Baqarah verse 233 and explain in easy language to village families why responsible parents do not have more children than they can care for. The 2nd step is to teach families to take social and family welfare into their own hands and not to submit to fatalism. The 3rd is to establish educational systems which systematically change families' attitudes and awaken them from outmoded practices. It is shown that of 28 million school age children in Indonesia, only 13 million can attend schools. By helping in this educational task, religious leaders will improve the outlook for these children and become a vital force in a changing Indonesia. PMID:12256866

    This paper presents interpretations of the satellite radar images of cloud-covered portions of Indonesia and Amazonia obtained from NASA's Shuttle imaging radar experiments in 1981 (SIR-A) and 1984 (SIR-B). It was found that different terrain categories observed from distinctive image textures correlate well with major lithologic associations. The images show geologic structures at regional and local scales. The SIR-B images of East Kalimantan, Indonesia, reveal structural features and terrain distributions that had been overlooked or not perceived in previous surface mapping. Variability in radar response from the vegetation cover is interpretable only in coastal areas or alluvial areas that are relatively level.

    Vast and disastrous fires occurred on Borneo during the 2015 dry season, pushing Indonesia into the top five carbon emitting countries. The region was affected by a very strong El Niño-Southern Oscillation (ENSO) climate phenomenon, on par with the last severe event in 1997/98. Fire dynamics in Central Kalimantan were investigated using an innovative sensor offering higher sensitivity to a wider range of fire intensities at a finer spatial resolution (160 m) than heretofore available. The sensor is onboard the TET-1 satellite, part of the German Aerospace Center (DLR) FireBird mission. TET-1 images (acquired every 2-3 days) from the middle infrared were used to detect fires continuously burning for almost three weeks in the protected peatlands of Sebangau National Park as well as surrounding areas with active logging and oil palm concessions. TET-1 detection capabilities were compared with MODIS active fire detection and Landsat burned area algorithms. Fire dynamics, including fire front propagation speed and area burned, were investigated. We show that TET-1 has improved detection capabilities over MODIS in monitoring low-intensity peatland fire fronts through thick smoke and haze. Analysis of fire dynamics revealed that the largest burned areas resulted from fire front lines started from multiple locations, and the highest propagation speeds were in excess of 500 m/day (all over peat > 2m deep).

    Vast and disastrous fires occurred on Borneo during the 2015 dry season, pushing Indonesia into the top five carbon emitting countries. The region was affected by a very strong El Niño-Southern Oscillation (ENSO) climate phenomenon, on par with the last severe event in 1997/98. Fire dynamics in Central Kalimantan were investigated using an innovative sensor offering higher sensitivity to a wider range of fire intensities at a finer spatial resolution (160 m) than heretofore available. The sensor is onboard the TET-1 satellite, part of the German Aerospace Center (DLR) FireBird mission. TET-1 images (acquired every 2–3 days) from the middle infrared were used to detect fires continuously burning for almost three weeks in the protected peatlands of Sebangau National Park as well as surrounding areas with active logging and oil palm concessions. TET-1 detection capabilities were compared with MODIS active fire detection and Landsat burned area algorithms. Fire dynamics, including fire front propagation speed and area burned, were investigated. We show that TET-1 has improved detection capabilities over MODIS in monitoring low-intensity peatland fire fronts through thick smoke and haze. Analysis of fire dynamics revealed that the largest burned areas resulted from fire front lines started from multiple locations, and the highest propagation speeds were in excess of 500 m/day (all over peat > 2m deep). Fires were found to occur most often in concessions that contained drainage infrastructure but were not cleared prior to the fire season. Benefits of implementing this sensor system to improve current fire management techniques are discussed. Near real-time fire detection together with enhanced fire behavior monitoring capabilities would not only improve firefighting efforts, but also benefit analysis of fire impact on tropical peatlands, greenhouse gas emission estimations as well as mitigation measures to reduce severe fire events in the future.

    In remote, tropical areas human influences increase, potentially threatening pristine seagrass systems. We aim (i) to provide a bench-mark for a near-pristine seagrass system in an archipelago in East Kalimantan, by quantifying a large spectrum of abiotic and biotic properties in seagrass meadows and (ii) to identify early warning indicators for river sediment and nutrient loading, by comparing the seagrass meadow properties over a gradient with varying river influence. Abiotic properties of water column, pore water and sediment were less suitable indicators for increased sediment and nutrient loading than seagrass properties. Seagrass meadows strongly responded to higher sediment and nutrient loads and proximity to the coast by decreasing seagrass cover, standing stock, number of seagrass species, changing species composition and shifts in tissue contents. Our study confirms that nutrient loads are more important than water nutrient concentrations. We identify seagrass system variables that are suitable indicators for sediment and nutrient loading, also in rapid survey scenarios with once-only measurements.

    Although climate change is a global concern, there are particular considerations for Indonesia as an archipelagic nation. These include the vulnerability of people living in small islands and coastal areas to rising sea levels; the expansion of the important mosquito-borne diseases, particularly malaria and dengue, into areas that lack of immunity; and the increase in water-borne diseases and malnutrition. This article proposes a set of public health responses to climate change health impacts in Indonesia. Some important principles and practices in public health are highlighted, to develop effective public health approaches to climate change in Indonesia. PMID:20032032

    In order to understand the role of raw meat and viscera eating habits in the transmission of taeniasis in Asian countries, 1502 infected aborigines in ten mountainous districts/towns of six counties in Taiwan, 58 infected persons in two villages on Cheju Island, Korea, and 97 cases in Ambarita District on Samosir Island, North Sumatra, Indonesia were studied during the field surveys. All infected Taiwan aborigines had the habit of eating raw meat and viscera of wild and/or domestic animals. Among these aborigines, 73% ate wild boar, 66% flying squirrel, 65% wild goat, 56% muntjac, 49% wild rats, 46% monkey, 38% hare, 20% civet-cats, 18% weasel, 17% pheasant, 14% squirrel, 4% grouse, 1% deer, 1% snake, less than 1% bamboo partridge, less than 1% frog, less than 1% bear, less than 1% dog, and less than 1% fox. Of the 58 infected persons with Taenia on Cheju Island, Korea, 72% ate raw meat and/or viscera of pig and cattle, 19% raw pork only, and 9% raw beef only. Among 12 infected persons infected with T. saginata-like tapeworms, 7 had eaten raw pork, 2 raw beef and pork and 3 raw pork. Almost all of the 97 cases of taeniasis on Samosir Island of North Sumatra, Indonesia, had eaten only undercooked pork. Eleven of 15 cases were found to be infected with T. saginata-like tapeworms. Eating habits observed suggest an unusual way of transmission of Taenia in East Asia. PMID:1356301

  11. Indonesia: community participation key to success.

    PubMed

    1984-12-01

    Population growth was first recognized as a serious problem in Indonesia in 1969, and attention was focused on 3 main aspects of the country's demographic structure: the population is the 5th largest after China, India, Union of Soviet Socialist Republics, and the US; the high rate of population growth, which was 24/1000 population in 1969; and the unequal spatial distribution of the population, with more than 66.4% living on the small islands of Java and Bali. To deal with these constraints to Indonesia's socioeconomic development, high priority was given to the initiation of a phased family planning program and enhancement of the organized population redistribution program. With regard to spatial population distribution, the biased economic development in urban areas in the 1970s led to an increasing flow of rural-urban migration, which placed too heavy a burden on the urban administrators in providing basic necessities of life and often resulted in the growth of slums and squatter settlements in urban areas. Taking into consideration these major constraints, the national family planning program is based on a 2-fold objective: to achieve the demographic goal of lowering the population growth rate through fertility decline and also to change traditional values toward acceptance of the small happy family norm among the people. At the end of the third 5-year period in 1983, remarkable results had been achieved in recruiting contraceptive users. To date around 14 million eligible couples are practicing family planning, and prevalence is particularly high in rural areas. Almost 60% of eligible couples are regulating their fertility through contraception. Behind these achievements are the high dedication of field workers and local administrators as well as a high level of community participation. Efforts are being made to curb Indonesia's mortality in order to improve the quality of life. The current high level of mortality -- 15/1000 population -- is mainly due to the

  12. Identification of recently active faults and folds in Java, Indonesia

    2013-12-01

    We analyze the spatial pattern of active deformation in Java, Indonesia with the aim of characterizing the deformation of the upper plate of the subduction zone in this region. The lack of detailed neotectonic studies in Java is mostly because of its relatively low rate of deformation in spite of significant historical seismic activity. In addition, the abundance of young volcanic materials as well as the region's high precipitation rate and vegetation cover obscure structural relationships and prevent reliable estimates of offset along active faults as well as exhumed intra-arc faults. Detailed maps of active faults derived from satellite and field-based neotectonic mapping, paleoseismic data, as well as new data on the fault kinematics and estimates of orientation of principal stresses from volcano morphology characterize recently active faults and folds. The structures in West Java are dominated by strike-slip faulting, while Central and northern part of East Java are dominated by folds and thrusting with minor normal faulting. The structures vary in length from hundreds meters to tens of kilometers and mainly trend N75°E, N8°E with some minor N45°W. Our preliminary mapping indicates that there are no large scale continuous structures in Java, and that instead deformation is distributed over wide areas along small structures. We established several paleoseismic sites along some of the identified structures. We excavated two shallow trenches along the Pasuruan fault, a normal fault striking NW-SE that forms a straight 13 km scarp cutting Pleistocene deltaic deposits of the north shore of East Java. The trenches exposed faulted and folded fluvial, alluvial and colluvial strata that record at least four ground-rupturing earthquakes since the Pleistocene. The Pasuruan site proves its potential to provide a paleoseismic record rarely found in Java. Abundant Quaternary volcanoes are emplaced throughout Java; most of the volcanoes show elongation in N100°E and N20

  4. Seasonal variations in geochemistry of the hyperacidic Ijen Crater Lake, East Java, Indonesia

    NASA Astrophysics Data System (ADS)

    Sumarti, S.; Sumarti, S.; van Bergen, M. J.; Takano, B.; Sukarnen, S.

    2001-12-01

    Kawah Ijen is a typical crater lake in a tropical climate where there is a balance between the volume of atmospheric precipitation and the level of water in the lake. The crater lake has a regular oval form (600 x 1000 m2), is 180 m deep, and contains about 36 million m3 of turquoise-green colored water (pH ~ 0.2). The water contains extremely high Cl, SO4, F concentrations, the maximum values being about 2,500 mg/kg, 80,000 mg/kg and 1,300 mg/kg respectively. Twenty-four samples of lake water taken during August 1996 (dry season) show most major elements to be homogeneously distributed throughout the lake at this time to a depth of 165 m within a standard deviation of less than 10 %. Homogeneity is most likely due to thorough mixing driven by thermal convection. However, iron and sulphur do not behave in the same way showing variations up to 14 % variation. Monthly monitoring of surface water (1997-2001) shows temporal fluctuations in acidity (pH 0 ~ 0.6) and water level, concentrations of major elements, temperature (20 ~ 45° C). Between 1976-1996, the water level varied by ~ 15 m; and from 1997-2001 by ~ 10 m. The onset of the wet season may coincide with an episodical decrease, a spike, in major element concentrations up to 70 % of their dry season value. This spike occurs annually at the lowest temperature and highest degree of dilution, indicates of the influence of rainfall. However, volcanic gases entering beneath the lake bottom may have added to these temporal changes in the lake especially during phreatic eruptions. Shallow earthquake records do not indicate correlations between seismic activity and chemical changes in the lake. Temporal variations of lake surface temperature show good agreement with major element variations in surface water. Crater lake surface water collected at three points on August 1996, March 2001, May 2001 revealed that the surface water was homogenous in the dry and rainy season within a standard deviation below 7 %. The geochemical and seasonal variations in the lake are important in assessing the environmental impact of acidic water that drains in to the Banyupahit-Banyuputih River, particularly in the Asembagus area (40 km from the lake) where the water is used for irrigation. The fluoride level in the 55 well water samples was high. In 50 % of the samples it was above the 1.5 mg/kg limit recommended by the World Health Organization (WHO). Ratios of B/F, B\\Cl, B/SO4 as conservative elements indicate that Banyuputih River contaminates the groundwater.

  5. Challenges modeling clastic eruptions: applications to the Lusi mud eruption, East Java, Indonesia.

    NASA Astrophysics Data System (ADS)

    Collignon, Marine; Schmid, Daniel; Mazzini, Adriano

    2016-04-01

    Clastic eruptions involve brecciation and transport of the hosting rocks by ascent fluids (gas and/or liquids), resulting in a mixture of rock clasts and fluids (i.e. mud breccia). This kind of eruptions is often associated with geological features such as mud volcanoes, hydrothermal vents or more generically with piercement structures. Over the past decades, several numerical models, often based on those used in volcanology, have been employed to better understand the behavior of such clastics systems. However, modeling multiphase flow is challenging, and therefore most of the models are considering only one phase flow. Many chemical, mechanical and physical aspects remain still poorly understood. In particular, the rheology of the fluid is one of the most important aspects, but also the most difficult to characterize. Experimental flow curves can be obtained on the finest fraction, but coarser particles (> 1mm) are usually neglected. While these experimental measurements usually work well on magma, they are much more difficult to perform when clay minerals are involved. As an initial step, we use analytical and simplified numerical models (flow in a pipe) to better understand the flow dynamics within a main conduit connected to an overpressured reservoir. The 2D numerical model solves the stokes equations, discretized on a finite element mesh. The solid phase is treated as rigid particles in suspension in the liquid. The gaseous phase (methane and carbon dioxide) is treated in an analytical manner using the equations of state of the H2O-CO2 and H2O-CH4 systems. Here, we present an overview of the state-of-the-art in modeling clastic eruptions as well as the limitations and challenges of such numerical models. We also discuss the challenges associated to the specific case of Lusi. In particular the difficulty to characterize the mud properties and the technical challenges associated with the acquisition of new data and development of more sophisticated models. Previous attempts to model e.g. the longevity of the Lusi eruption were not particularly successful. A possibility is because the sedimentary hosted hydrothermal system is reactivated by frequent seismicity and by the connection with the neighboring volcanic complex feeding it.

    Indonesia is one of the biggest dengue endemic countries, and, thus, is an important place to investigate the evolution of dengue virus (DENV). We have continuously isolated DENV in Surabaya, the second biggest city in Indonesia, since 2008. We previously reported sequential changes in the predominant serotype from DENV type 2 (DENV-2) to DENV type 1 (DENV-1) in November 2008 and from DENV-1 to DENV-2 in July 2013. The predominance of DENV-2 continued in 2014, but not in 2015. We herein phylogenetically investigated DENV-2 transitions in Surabaya between 2008 and 2014 to analyze the divergence and evolution of DENV-2 concomitant with serotype shifts. All DENV-2 isolated in Surabaya were classified into the Cosmopolitan genotype, and further divided into 6 clusters. Clusters 1-3, dominated by Surabaya strains, were defined as the "Surabaya lineage". Clusters 4-6, dominated by strains from Singapore, Malaysia, and many parts of Indonesia, were the "South East Asian lineage". The most recent common ancestor of these strains existed in 1988, coinciding with the time that an Indonesian dengue outbreak took place. Cluster 1 appeared to be unique because no other DENV-2 isolate was included in this cluster. The predominance of DENV-2 in 2008 and 2013-14 were caused by cluster 1, whereas clusters 2 and 3 sporadically emerged in 2011 and 2012. The characteristic amino acids of cluster 1, E-170V and E-282Y, may be responsible for its prevalence in Surabaya. No amino acid difference was observed in the envelope region between strains in 2008 and 2013-14, suggesting that the re-emergence of DENV-2 in Surabaya was due to the loss or decrease of herd immunity in the 5-year period when DENV-2 subsided. The South East Asian lineage primarily emerged in Surabaya in 2014, probably imported from other parts of Indonesia or foreign countries.

    2014-07-01

    Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

    Cancer is a major cause of mortality and morbidity throughout the world, including the countries of North-East and South-East Asia. Assessment of burden through cancer registration, determination of risk and protective factors, early detection and screening, clinical practice, interventions for example in vaccination, tobacco cessation efforts and palliative care all should be included in comprehensive cancer control programs. The degree to which this is possible naturally depends on the resources available at local, national and international levels. The present review concerns elements of cancer control programs established in China, Taiwan, Korea, and Japan in North-East Asia, Viet Nam, Thailand, Malaysia, and Indonesia as representative larger countries of South-East Asia for comparison, using the published literature as a guide. While major advances have been made, there are still areas which need more attention, especially in South-East Asia, and international cooperation is essential if standard guidelines are to be generated to allow effective cancer control efforts throughout the Far East.

    Observations are made related to the review of family planning activities in East Asia in 1973. The number of new acceptors for the region increased from 2.7 million in 1972 to 3.4 million in 1973. The leaders were Indonesia, which almost doubled its achievement of calendar year 1972, the Philippines, and Korea. In Thailand, the number of new acceptors dropped by about 10%. South Vietnam is the only country in the region without an official policy. Most couples still think that the ideal number of children is 4, with at least 2 sons. Some religious opposition does exist, particularly with reference to sterlization and abortion. More attention is being paid to women in their 20s. Sterilization and condoms are becoming more popular. Korea reports a sharp increase in vasectomies. Better methods and continuation rates should be stressed. In Taiwan a couple who start with 1 method and continue to practice some method lower their reproduction rate by 80%. More responsibility is being delegated to nurses and midwives, but too slowly. In Indonesia, the number of field workers rose from 3774 in 1972 to 6275 in 1973. The Philippines and Thailand are experimenting to see what kind of workers get best results and under what kind of salary and incentive arrangements. In-service training tends to be neglected, but preservice training is improving. Costs, in general, have risen, though in Korea the cost per acceptor has dropped from US$8.00 to US$7.80. Korea and Taiwan have reduced their annual population growth rates by more than 1/3 in 10 years, from 30 to 19-20 per 1000 each. Singapore's rate is 17 and Hong Kong's 14 (exclusive of inmigration). The number of couples currently practicing contraception in Singapore is 71%. Target systems assigning quotas to clinics are generally used except in Thailand and Malaysia, where programs emphasize maternal and child health, rather than population planning. Most programs require about 10 years to get the annual growth rate down to 2% by

    Limited availability of IEC materials is hindering efforts to promote adolescent reproductive health in Indonesia. This, in turn, reflects a lack of awareness on the part of policy makers and community leaders about the importance of interventions directed at young people. Two ongoing United Nations Population Fund projects seek to promote awareness of adolescent reproductive health needs in Jakarta, Yogyakarta, West Java, Bali, Lampung, and Riau. A coalition of governmental and nongovernmental agencies has been established to implement the project. By project end in 1999, government agencies and nongovernmental organizations are expected to have incorporated youth-oriented activities into their overall programming and formulated relevant policy guidelines. Another project (Strengthening Strategies to Improve Adolescent Reproductive Health through Materials Development), implemented by the Indonesian Planned Parenthood Association, is focusing on the development and distribution of reproductive health materials for specific target audiences.

    Because of the active tectonic setting of the region, the risks of geological hazards inevitably increase in Indonesian Archipelagoes and other ASIAN countries. Encouraging community living in the vulnerable area to adapt with the nature of geology will be the most appropriate strategy for earthquake risk reduction. Updating the Earthquake Hazard Maps, enhancement ofthe existing landuse management , establishment of public education strategy and method, strengthening linkages among stake holders of disaster mitigation institutions as well as establishement of continues public consultation are the main strategic programs for community resilience in earthquake vulnerable areas. This paper highlights some important achievements of Earthquake Hazard Mitigation Programs in Indonesia, together with the difficulties in implementing such programs. Case examples of Yogyakarta and Bengkulu Earthquake Mitigation efforts will also be discussed as the lesson learned. The new approach for developing earthquake hazard map which is innitiating by mapping the psychological aspect of the people living in vulnerable area will be addressed as well.

  16. Scientists assess impact of Indonesia fires

    Showstack, Randy

    The fires burning in Indonesia over the past several months are setting aflame the biomass and wildlife habitat of the tropical forests, spreading a dangerously unhealthy haze across the populous country and nearby nations in southeast Asia, causing transportation hazards, and sending plumes of smoke up into the troposphere.Most of the fires have been set—by big landowners, commercial loggers, and small farmers—in attempts to clear and cultivate the land, as people have done in the past. But this year a drought induced by El Niño limited the rainfall that could help extinguish the flames and wash away the smoke and haze. In addition, some scientists say that smoke could even delay the monsoon, which usually arrives in early November.

    2014-06-01

    We present, for the first time, evidence for triggered tremor beneath the island of Sumbawa, Indonesia. We show triggered tremor in response to three teleseismic earthquakes: the Mw9.0 2011 Tohoku earthquake and two oceanic strike-slip earthquakes (Mw 8.6 and Mw8.2) offshore of Sumatra in 2012. We constrain an apparent triggering threshold of 1 mm/s ground velocity that corresponds to about 8 kPa dynamic stress. Peak tremor amplitudes of about 180 nm/s are observed, and scale with the ground velocity induced by the remote earthquakes. Triggered tremor responds to 45-65 s period surface waves and predominantly correlates with Rayleigh waves, even though the 2012 oceanic events have stronger Love wave amplitudes. We could not locate the tremor because of minimal station coverage, but data indicate several potential source volumes including the Flores Thrust, the Java subduction zone, or Tambora volcano.

    2016-01-01

    This paper responds to recent calls for empirical study of the impact of age-structural transition. It begins by reviewing evidence of cohort oscillations in twentieth-century Indonesia, which indicates that current older generations are likely to have smaller numbers of children on whom they may rely than generations before and after them. However, to assess whether the imbalances implied by this situation are actually influencing people’s lives, attention to further factors shaping the availability and reliability of younger generations, notably differences in socio-economic status and in patterns of inter-generational support flows, is required. Community-level Indonesian data confirm that elders in the lower social strata are child-poor. Social structural and family network patterns, however, have a greater influence on the availability of inter-generational support than cohort differentials. PMID:27158254

    This study investigates the relationship between economic trends and entry into marriage in a rapidly developing setting. We examine Indonesian marriage in the 1990’s, a decade of substantial economic growth followed by a sudden financial collapse in 1998. We use discrete-time hazard models to analyze information on 4,078 women and 4,496 men from the Indonesia Family Life Survey. While previous research has shown that marriages may be postponed after economic downturn, we find no evidence of such delays at the national level following the 1998 financial crisis. In contrast, we use regional wage rate data to show that entry into marriage is inversely related to economic growth throughout the decade for all women and for men from lower socioeconomic strata.

    THE ACCEPTANCE STRATEGY FOR NUCLEAR POWER PLANT IN INDONESIA. Indonesia has planned to build nuclear power plants. Some feasibility studies have been conducted intensively. However, the processes of NPP introduction are still uncertain. National Energy Plan in Indonesia, which has been made by some governmental agencies, does not yet give positive impact to the government decision to construct the nuclear power plant (NPP). This paper discusses the process of NPP introduction in Indonesia, which has been colored with debate of stakeholder and has delayed decision for go-nuclear. The technology paradigm is used to promote NPP as an alternative of reliable energy resources. This paradigm should be complemented with international politic-economic point of view. The international politic-economic point of view shows that structural powers, consisting of security, production, finance, and knowledge structures, within which the NPP is introduced, have dynamic characteristics. The process of NPP introduction in Indonesia contains some infrastructure development (R&D, legislation, regulation, energy planning, site study, public acceptance efforts, etc), but they need a better coherent NPP implementation program and NPP Acceptance Program. Strategic patterns for NPP acceptance described in this paper are made by considering nuclear regulation development and the interest of basic domestic participation. The first NPP program in Indonesia having proven technology and basic domestic participation is and important milestone toward and optimal national energy-mix.

    Energy consumption in Indonesia is growing fast in line with the development of national economy. During (1990 - 1993) the emission of CO{sub 2} gas coming from energy sector increased from 150 million tones to 200 million tones in 1993. Whereas, the total methane emission from the oil, gas and coal sub-sector reached 550 kilo tones in 1991 and increased to 670 kilo tones in 1994. This amount of CO{sub 2} and Methane from energy sector was 26% and 10 % respectively of the total emission of Indonesia. Based on the last two decades of Indonesia`s economic growth experience, as a developing country this high economic growth rate of Indonesia in the future will be kept until reaching the newly industrialized country level, which is more than 6% annually in the next decade. This high growth rate economic projection will also added the level of GHG emission in the future. As a developing country Indonesia is one of the fast growing countries. The GDP growth in the year 1995 was more than 7 percent, therefore growth rate of energy consumption in this country also rose following the economic growth.

    This research note aims to understand the impact of parental migration on the children who stay behind by examining the issue of smoking. It asks whether tobacco use and exposure are higher among children in migrant households compared with those in non-migrant households in Java, Indonesia. Data were collected in 2008 in two provinces, West Java and East Java, as part of the Child Health and Migrant Parents in South-East Asia (CHAMPSEA) Project. The analytical sample used here relates to children aged 9, 10 and 11 living in both non-migrant and transnational households (N=451). The findings show that the incidence of ever having smoked among these primary school-aged children is relatively low at less than 10 percent, but that boys are much more likely to have used tobacco than girls. Findings from multivariate logistic models predicting smoking behavior show no difference between the children of migrants and non-migrants; nor does household wealth appear to influence whether or not a child has tried tobacco. Gender, child stunting (low height-for-age), carer’s education, family functioning and tobacco use by friends are the four main factors found to be significantly associated with child smoking.

    A recent field expedition in Central Java targeted the mapping and sampling of several piercements structures in central Java (Indonesia), most of which have never been documented before. Here, at least seven structures erupting mud water and gas are distributed along a NE-SW alignment that extends for about 10 kilometers. Some of the mapped structures (Bledug Kuwu, Bledug Cangkring Krabagan, Mendikil, Banjarsari, Krewek) have been named after the neighboring local village. None of these have obvious elevation despite the vigorous emission of gas and mud, suggesting that significant caldera collapse is ongoing. Among the most relevant: Bledug Kuwu is certainly the most impressive structure with three main eruption sites in the crater area bursting more than 5 m large hot mud bubbles. Similar characteristics are present at the smaller (200 m in diameter) Bledug Cangkring Krabagan, that is also surrounded by numerous pools and gryphons seeping around the main crater. The smaller sized Mendikil is the only visited structure that, at the moment of the sampling, did not show seepage of hot fluids. Banjarsari and Krewek (up to 200 m wide) are characterized by scattered hot water-dominated pools where gas is vented vigorously. In particular the hot pools are systematically covered by travertine concretions. Water and gas geochemisty confirms the seepage of CO2 dominated gas and water with hydrothermal signature. The investigated structures appear to follow an obvious NE-SW oriented lineament that most likely coincides with a tectonic structure (fault?) that controls their location. Indeed the field observations and the analyses suggest that likely scenario is that this fault (?) acts as a preferential pathway for the expulsion of hydrothermal fluids to the surface. Very little is known about this region, neither is known why several of these structures erupt hot mud despite their significant distance from the two closest volcanic structures (i.e. Mt.

    2012-01-01

    Background The Indonesia Maternal Mortality Rate (MMR) of 420/100.00 live births remains among the highest in East Asia while coverage of births assisted by skilled providers is still low. Traditional beliefs have been a key factor associated with the choice between midwives or traditional birth attendants (TBA) and the low number of antenatal care visits in rural West Sumatra. Methods We conducted three focus groups with 16 women from rural West Java to describe their perception regarding issues related to traditional beliefs. Focus group discussions provided data for the content analysis. Results The majority of the 16 women interviewed was from Village Dago, West Java and had only an elementary school education. Their ages ranged from 19 to 40 years. Most were multiparous housewives with an income of IDR 918.750 per month, which was lower than the monthly income in West Java (IDR. 1.172.060). Emerging from the focus group discussion were four main themes regarding their pregnancy and traditional beliefs: 1) pregnancy was a normal cycle in women’s life (pregnancy is a natural phenomena, not a sickness; no recognition of danger signs during pregnancy and death of baby or mother during pregnancy was brought about by God’s will); 2) women followed the traditional beliefs (positive motivation to follow the traditional beliefs and fear of not following the traditional beliefs); 3) relying on TBA called paraji rather than midwife (parajis are kind, tolerant and patient and have more experience than midwives; more accessibility than midwives and encouragement of natural birth) and 4) midwives are more secure than paraji; (they use a medical standard of care). Conclusions Women’s beliefs grounded in religion and tradition permeated the village culture making it difficult to counter their long held health practices with practices based on recent advances in health care. Use of TBA in this village was still dominant and women believed that following traditional

    The Banda Arc of Indonesia remains one of the least understood tectonic domains on the modern Earth. The island of Sumba, located approximately 50 km south of Flores and 120 km north of the Java Trench, northwest of where it transitions into the Timor Trough, lies in a region of tectonic transition and potentially offers insights into regional dynamics. The Banda Arc is volcanically active, but Sumba itself is not volcanic. The northern coast of Sumba is covered in Quaternary coral terraces, with the rest of the island's surface geology composed of Mio-pliocene carbonates and uplifted Late Cretaceous-Oligocene forearc basin and volcanic rocks. The purpose of this study is to remotely map the topographic expression of the coral terraces and use the information gained to better understand deformation on Sumba since their deposition. The ages of the coral terraces, of which many platforms are exposed over significant areas of the island, have been constrained at Cape Luandi in north central Sumba, but uplift rates calculated from those ages may not be representative of the island as a whole. The lateral continuity of these dated terraces can help constrain the extent to which uplift of Sumba is spatially variable. Analysis of the terraces using SRTM digital elevation data with ArcGIS software makes it possible to trace the same terrace platforms over large distances, and shows that the north central part of the island has experienced the most uplift since the deposition of the terraces, forming an anticline with the east limb dipping more steeply than the west. The terraces are not well preserved on the southern half of the island. Exposure of older rocks and lack of terrace preservation, as well as a south-skewed drainage divide suggests the southern half of the island experiences greater exhumation, but this could be driven by climate or other factors and does not necessarily indicate more rapid uplift. Study of Quaternary deformation of Sumba can offer greater

    East Asian observations are of established importance in Applied Historical Astronomy. The earliest astronomical records from this part of the world (China, Japan and Korea) originate from China. These observations, mainly of lunar eclipses, are recorded on oracle bones from the period ca. 1300 - 1050 BC. Virtually all later Chinese and other East Asian astronomical records now exist only in printed copies. The earliest surviving series of solar eclipse observations from any part of the world is contained in the Chunqiu (722 - 481 BC), a chronicle of the Chinese state of Lu. However, not until after 200 BC, with the establishment of a stable empire in China, do detailed astronomical records survive. These are mainly contained in specially compiled astrological treatises in the official dynastic histories. Such records, following the traditional style, extend down to the start of the present century. All classes of phenomena visible to the unaided eye are represented: solar and lunar eclipses, lunar and planetary movements among the constellations, comets, novae and supernovae, meteors, sunspots and the aurora borealis. Parallel, but independent series of observations are recorded in Japanese and Korean history, especially after about AD 800. Sources of Japanese records tend to be more diverse than their Chinese and Korean counterparts, but fortunately Kanda Shigeru (1935) and Ohsaki Shyoji (1994) have made extensive compilations of Japanese astronomical observations down to the 1860s. Throughout East Asia, dates were expressed in terms of a luni-solar calendar.

  12. Remotely triggered nonvolcanic tremor in Sumbawa, Indonesia

    NASA Astrophysics Data System (ADS)

    Fuchs, Florian; Lupi, Matteo; Miller, Stephen

    2015-04-01

    Nonvolcanic (or tectonic) tremor is a seismic phenomenom which can provide important information about dynamics of plate boundaries but the underlying mechanisms are not well understood. Tectonic tremor is often associated with slow-slip (termed episodic tremor and slip) and understanding the mechanisms driving tremor presents an important challenge because it is likely a dominant aspect of the evolutionary processes leading to tsunamigenic, megathrust subduction zone earthquakes. Tectonic tremor is observed worldwide, mainly along major subduction zones and plate boundaries such as in Alaska/Aleutians, Cascadia, the San Andreas Fault, Japan or Taiwan. We present, for the first time, evidence for triggered tremor beneath the island of Sumbawa, Indonesia. The island of Sumbawa, Indonesia, is part of the Lesser Sunda Group about 250 km north of the Australian/Eurasian plate collision at the Java Trench with a convergence rate of approximately 70 mm/yr. We show surface wave triggered tremor beneath Sumbawa in response to three teleseismic earthquakes: the Mw9.0 2011 Tohoku earthquake and two oceanic strike-slip earthquakes (Mw 8.6 and Mw8.2) offshore of Sumatra in 2012. Tremor amplitudes scale with ground motion and peak at 180 nm/s ground velocity on the horizontal components. A comparison of ground motion of the three triggering events and a similar (nontriggering) Mw7.6 2012 Philippines event constrains an apparent triggering threshold of approximately 1 mm/s ground velocity or 8 kPa dynamic stress. Surface wave periods of 45-65 s appear optimal for triggering tremor at Sumbawa which predominantly correlates with Rayleigh waves, even though the 2012 oceanic events have stronger Love wave amplitudes and triggering potential. Rayleigh wave triggering, low-triggering amplitudes, and the tectonic setting all favor a model of tremor generated by localized fluid transport. We could not locate the tremor because of minimal station coverage, but data indicate several

  13. Dynamic triggering of Lusi, East Java Basin

    2016-04-01

    On the 27th of May 2006, a M6.3 strike slip earthquake struck beneath Yogyakarta, Java. Forty-seven hours later a mixture of mud, breccia, and gas reached the surface near Sidoarjo, 250 km far from the epicenter, creating several mud vents aligned along a NW-SE direction. The mud eruption reached a peak of 180.000 km3 of erupted material per day and it is still ongoing. The major eruption crater was named Lusi and represents the surface expression of a newborn sedimentary-hosted hydrothermal system. Lusi flooded several villages causing a loss of approximately 4 billions to Indonesia. Previous geochemical and geological data suggest that the Yogyakarta earthquake may have reactivated parts of the Watukosek fault system, a strike slip structure upon which Lusi resides. The Watukosek fault systems connects the East Java basin to the volcanic arc, which may explain the presence of both biogenic and thermogenic fluids. To quantify the effects of incoming seismic energy at Lusi we conducted a seismic wave propagation study on a geological model of Lusi's structure. A key feature of our model is a low velocity shear zone in the Kalibeng formation caused by elevated pore pressures, which is often neglected in other studies. Our analysis highlights the importance of the overall geological structure that focused the seismic energy causing elevated strain rates at depth. In particular, we show that body waves generated by the Yogyakarta earthquake may have induced liquefaction of the Kalibeng formation. As consequence, the liquefied mud injected and reactivated parts of the Watukosek fault system. Our findings are in agreement with previous studies suggesting that Lusi was an unfortunate case of dynamic triggering promoted by the Yogyakarta earthquake.

    Previous lahar disasters caused at least 44.252 death toll worldwide from 1600 to 2010 of which 52 % was due to a single event in the late 20th century. The need of a better understanding of lahar flow behavior makes general public and stakeholders much more curious than before. However, the dynamics of lahar in motion is still poorly understood because data acquisition of active flows is difficult. This research presents debris-flow-type lahar on February 28, 2014 at Merapi volcano in Indonesia. The lahar dynamics was studied in the frame of the SEDIMER Project (Sediment-related Disasters following the 2010 centennial eruption of Merapi Volcano, Java, Indonesia) based on coupling between video and seismic data analysis. We installed a seismic station at Gendol river (1090 meters asl, 4.6 km south from the summit) consisting of two geophones placed 76 meters apart parallel to the river, a high definition camera on the edge of the river and two raingauges at east and west side of the river. The results showed that the behavior of this lahar changed continuously during the event. The lahar front moved at an average speed of 4.1 m/s at the observation site. Its maximum velocity reached 14.5 m/s with a peak discharge of 473 m3/s. The maximum depth of the flow reached 7 m. Almost 600 blocks of more than 1 m main axis were identified on the surface of the lahar during 36 minutes, which represents an average block discharge of 17 blocks per minute. Seismic frequency ranged from 10 to 150 Hz. However, there was a clear difference between upstream and downstream seismic characteristics. The interpretation related to this difference could be improved by the results of analysis of video recordings, especially to differentiate the debris flow and hyperconcentrated flow phase. The lahar video is accessible online to the broader community (https://www.youtube.com/watch?v=wlVssRoaPbw). Keywords: lahar, video, seismic signal, debris flow, hyperconcentrated flow, Merapi, Indonesia.

    Pasasa, Linus; Fechter, Nadine; Bustaman, Yosman

    2010-12-01

    This paper examines the characteristics of short-term and long-term fluctuations/volatility of Indonesia exchange rate and investigates whether this volatility has affected Indonesia's exports flows. In particular the paper investigates the impact of exchange rate volatility on aggregate Indonesia exports flows to the United State and also on imports. The Augmented Dickey-Fuller Test was employed on quarterly data for the period January 2000 to December 2008 to test for stationarity on the variables of interest. Estimates of the long-term influence of exchange rate volatility on the trade flows are obtained using the Johansen Cointegration Test. The results suggest that a significant long-term relationship linking exchange rate volatility and the trade volume between Indonesia and the United States exists. A negative long-term relationship between exchange rate fluctuations and the export volume sent from Indonesia to the US is obtained. On the other hand, exchange rate volatility exerts a positive long-term effect upon the import volume.

    The introduction of pentavalent vaccine containing Haemophilus influenzae type b antigen in Indonesia's National Immunization Program occurred nearly three decades after the vaccine was first available in the United States and 16 years after Indonesia added hepatitis B vaccine into the program. In this study, we analyzed the process that led to the decision to introduce pentavalent vaccine in Indonesia. Using process tracing and case comparison, we used qualitative data gathered through interviews with key informants and data extracted from written sources to identify four distinct but interrelated processes that were involved in the decision making: (a) pentavalent vaccine use policy process, (b) financing process, (c) domestic vaccine development process and (d) political process. We hypothesized that each process is associated with four necessary conditions that are jointly sufficient for the successful introduction of pentavalent vaccine in Indonesia, namely (a) an evidence-based vaccine use recommendation, (b) sufficient domestic financing capacity, (c) sufficient domestic vaccine manufacturing capacity and (d) political support for introduction. This analysis of four processes that led to the decision to introduce a new vaccine in Indonesia may help policy makers and other stakeholders understand and manage activities that can accelerate vaccine introduction in the future.

    Kobe-Indonesia Collaborative Research Center was established in Institute of Tropical Disease (ITD), Airlangga University, Surabaya, Indonesia in 2007 under the program of ''Founding Research Centers for Emerging and Reemerging Infectious Diseases'' supported by the Ministry of Education, Culture, Sports, Science and Technology, Japan, and then it has been under the Japan Initiative for Global Research Network on Infectious Diseases (J-GRID) since 2010. Japanese researchers have been stationed at ITD, conducting joint researches on influenza, viral hepatitis, dengue and infectious diarrhea. Also, another Japanese researcher has been stationed at Faculty of Medicine, University of Indonesia, Jakarta, carrying out joint researches on'' Identification of anti-hepatitis C virus (HCV) substances and development of HCV and dengue vaccines'' in collaboration with University of Indonesia and Airlangga University through the Science and Technology Research Partnership for Sustainable Development (SATREPS) supported by the Japan Science and Technology Agency (JST) and Japan International Cooperation Agency (JICA) since 2009. In this article, we briefly introduce the background history of Kobe University Research Center in Indonesia, and discuss the research themes and outcomes of J-GRID and SATREPS activities.

  19. The hematopoietic stem cell transplantation in Indonesia: an unsolved dilemma.

    Allogeneic BMT was performed in Indonesia, but had to be stopped prematurely because of the small number of patients. In the beginning, only patients with sufficient financial resources to travel to western countries could undergo transplant procedures. When neighbouring countries (Singapore and Malaysia) began performing transplant, patients were referred to those centres. In both countries, the procedure is more economical and therefore patients come from a broader range of economic classes. The Indonesian hematologist must deal with the post-transplantation side effects, such as GVHD, which are mostly of the chronic type of GVHD. The types of the post-transplant complications do not differ too much from other centres and need the same treatment used in the transplant centres. Hematologists in Indonesia also treat complications of HSCT performed in other countries. When there is no recovery of HSCT development in Indonesia so far, many commercially oriented companies or centres from other countries see Indonesia as a good commercial market and offer services, some of which are not scientifically sound. One of the main problems is umbilical cord blood stem cell banking from foreign countries, which is eagerly offered to parents expecting a baby. Moreover, parents are not fully protected by law. In conclusion, Indonesia needs to revive its own HSCT program to serve and protect its own patients of being used as commercial targets by other countries. PMID:18724313

    New well data from Somalia, together with the history of sea-floor spreading in the Indian Ocean derived from magnetic anomalies, show that the East African margins from latitude 15/sup 0/S into the Gulf of Aden comprise four distinct segments that formed successively by the southward drift of Madagascar from Somalia during the Middle to Late Jurassic and Early Cretaceous, by the northeastward drift of India along the Owen Transform during the Late Cretaceous and Paleocene, and by the opening of the Gulf of Aden during the Neogene.

  1. Subduction in eastern Indonesia: how many slabs?

    2001-08-01

    Seismicity associated with arc-continent collision in eastern Indonesia testifies to past north-directed subduction of Indian Ocean lithosphere beneath the Banda Sea. The complex patterns of deep seismicity have been cited as evidence for simultaneous south-directed subduction at the northern margin of the sea but this interpretation has not been universally accepted. Recently available recomputations of hypocentre locations have provided increased resolution of eastern Indonesian Wadati-Benioff Zones (WBZs). Shallow to intermediate depth seismic activity around the Banda Arc appears to support models involving subduction of two separate and distinct lithospheric slabs, but between 150 and 500 km the WBZ has a continuous 'shoehorn' shape. This shape confirms the presence of subducted lithosphere beneath Seram, in the north, as well as beneath Timor, in the south, is incompatible with independent subduction of two unconnected plates and implies rapid eastwards retreat of the subduction trace across a now vanished northern spur of the Indian Ocean. This 'roll-back' is unlikely to have been driven by local gravitational forces alone and may have been sustained by injection behind the Banda slab of asthenospheric material escaping from the Molucca Sea arc-arc collision.

    A parasitology survey was conducted in five villages in North Sumatra, Indonesia. A total of 3,207 blood smears, 2,066 stool specimens and 969 sera were examined. Sixty (1.9%) inhabitants had malaria (Plasmodium vivax 41, P. falciparum 19), and 20 had Brugia malayi microfilaraemia. The most common intestinal helminths were Trichuris trichiura (87%), Ascaris lumbricoides (75%) and hookworm (58%). Other helminths found in low numbers were Enterobius vermicularis, Strongyloides stercoralis, Taenia sp., Fasciolid, Dicrocoeliid and Echinostoma sp. eggs. Entamoeba coli (25%) was the most common intestinal protozoa followed by Endolimax nana (8%), Entamoeba histolytica (7%), Giardia lamblia (6%), Iodamoeba bütschlii (5%), Entamoeba hartmanni (1%) and Chilomastix mesnili (1%). The amoeba prevalence rate was 31 per cent. Testing of sera for Entamoeba histolytica and Toxoplasma gondii antibodies by the indirect haemagglutination test demonstrated positive reactors in 13 per cent and nine per cent of the population respectively. The greatest number of seropositives for Toxoplasma gondii was at elevations of sea level to five meters and the lowest number at elevations of 5OO-1,000 meters. PMID:950682

    The tsunami brought into focus many issues related to mental health and psychosocial distress. A prompt response to the disaster relies on existing disaster management plans so that appropriate interventions can be put in place in order to meet the needs of the affected populations. The response must involve both physical and psychological aspects of care. The Indonesian experience was unique in a number of ways and it allowed us to explore the lessons in order to develop strategies to maximize the resources in order to ensure that the whole affected population was cared for. Massive destruction of the physical structures and the work force made the task particularly difficult. Existing policies did not include psychosocial efforts in the plan. However, mental health and psychosocial relief efforts are now being integrated into the disaster preparedness plan of Indonesia. To further implement the plan, a strong community mental health system is being developed. This system will be able to deliver mental health and psychosocial interventions on a routine basis and could be scaled up in times of disasters. PMID:17162698

    Within mathematics curricula, algebra has been widely recognized as one of the most difficult topics, which leads to learning difficulties worldwide. In Indonesia, algebra performance is an important issue. In the Trends in International Mathematics and Science Study (TIMSS) 2007, Indonesian students' achievement in the algebra domain was significantly below the average student performance in other Southeast Asian countries such as Thailand, Malaysia, and Singapore. This fact gave rise to this study which aims to investigate Indonesian students' difficulties in algebra. In order to do so, a literature study was carried out on students' difficulties in initial algebra. Next, an individual written test on algebra tasks was administered, followed by interviews. A sample of 51 grade VII Indonesian students worked the written test, and 37 of them were interviewed afterwards. Data analysis revealed that mathematization, i.e., the ability to translate back and forth between the world of the problem situation and the world of mathematics and to reorganize the mathematical system itself, constituted the most frequently observed difficulty in both the written test and the interview data. Other observed difficulties concerned understanding algebraic expressions, applying arithmetic operations in numerical and algebraic expressions, understanding the different meanings of the equal sign, and understanding variables. The consequences of these findings on both task design and further research in algebra education are discussed.

    In Indonesia, more than 200 illegal used lead acid battery (ULAB) smelters are currently operating. Only a few health studies support the finding of lead-related symptoms and diseases among populations living near the smelters. To assess the blood lead levels (BLLs) and potential health impacts among the population surrounding ULAB recycling smelters, we evaluated health effects reported from 2003 to 2013, conducted focus group discussions with lead smelter owner/workers and a group of 35 female partners of smelter owners or workers not actively engaged in smelter work, and retook and measured BLLs. It was found that many children in the areas were having difficulty achieving high grades at school and having stunting or other problems with physical development. The average mean of BLLs increased by almost double in 2015, compared with in 2011. The risk of having hypertension, interference in the ability to make red blood cells in females occurred among 24% of respondents; Elevated blood pressure, hearing loss, and interference in the ability to make red bloods cell occurred in 20% of males; Kidney damage, infertility in male, nerve problems, including decreased sensation and decreased ability to move quickly occurred in 13%; Decreased ability to make red blood cells (20%), and; Frank anemia, decreased life-span, coma/seizures were experienced by 22%. The populations living in areas surrounding ULAB smelters are experiencing severe chronic health problems. It is recommended that the smelters must be moved and placed far away from the municipality.

    As part of a multidisciplinary study of the population of Bali, Indonesia, treponemal serology was carried out on 2452 serum samples from subjects of both sexes. Sera reactive to the Treponema pallidum immobilisation test (TPI) were found in 81 (3.3%) subjects with a male prevalence of 4% and a female prevalence of 2%. All the reactive sera were from villagers. Of 1118 students sampled in various towns, none had reactive TPI tests. The prevalence of reactive sera varied greatly from one village to another; up to 50% of the sera examined were reactive. Geographical and socioeconomic analyses of the data show a strict correlation between poor socioeconomic status and high reactivity rates to the TPI test. Fifty-seven per cent of all the reactive sera originated from subjects living in two districts where yaws had recently been reported. Only three of the 1406 subjects, aged 15-29 years, had reactive sera. The reactivity rate steadily increased in the age groups 30-44, 45-59, and 60 years and over. Biological false-positive reactions occurred in 3.8% of the sera tested. PMID:6756541

    Semarang is one of the biggest cities in Indonesia and nowadays suffering from extended land subsidence, which is due to groundwater withdrawal, to natural consolidation of alluvium soil and to the load of constructions. Land subsidence causes damages to infrastructure, buildings, and results in tides moving into low-lying areas. Up to the present, there has been no comprehensive information about the land subsidence and its monitoring in Semarang. This paper examines digital elevation model (DEM) and benchmark data in Geographic Information System (GIS) raster operation for the monitoring of the land subsidence in Semarang. This method will predict and quantify the extent of subsidence in future years. The future land subsidence prediction is generated from the expected future DEM in GIS environment using ILWIS package. The procedure is useful especially in areas with scarce data. The resulting maps designate the area of land subsidence that increases rapidly and it is predicted that in 2020, an area of 27.5 ha will be situated 1.5 2.0 m below sea level. This calculation is based on the assumption that the rate of land subsidence is linear and no action is taken to protect the area from subsidence.

    Despite the high endemicity of hepatitis A virus (HAV) in Indonesia, genetic information on those HAV strains is limited. Serum samples obtained from 76 individuals during outbreaks of hepatitis A in Jember (East Java) in 2006 and Tangerang (West Java) in 2007 and those from 82 patients with acute hepatitis in Solo (Central Java), Denpasar on Bali Island, Mataram on Lombok Island, and Makassar on Sulawesi Island in 2003 or 2007 were tested for the presence of HAV RNA by reverse transcription PCR with primers targeting the VP1-2B region (481 nucleotides, primer sequences at both ends excluded). Overall, 34 serum samples had detectable HAV RNA, including at least one viremic sample from each of the six regions. These 34 strains were 96.3-100 % identical to each other and formed a phylogenetic cluster within genotype IA. Six representative HAV isolates from each region shared 98.3-98.9 % identity over the entire genome and constituted a IA sublineage with a bootstrap value of 100 %, consisting of only Indonesian strains. HAV strains recovered from Japanese patients who were presumed to have contracted HAV infection while visiting Indonesia were closest to the Indonesian IA HAV strains obtained in the present study, with a high identity of 99.5-99.7 %, supporting the Indonesian origin of the imported strains. These results indicate that genetic analysis of HAV strains indigenous to HAV-endemic countries, including Indonesia, are useful for tracing infectious sources in imported cases of acute hepatitis A and for defining the epidemiological features of HAV infection in that country.

    The government of Indonesia plans to intensify the utilization of geothermal energy for electrical generation as part of its energy diversification policy. Presently only 1.6% of the 19,650 megawatts country-wide potential are being utilized. To accelerate the development of geothermal energy, the government invites private companies as Contractor to cooperate with PERTAMINA, the State Company that is authorized to explore and exploit oil, gas and geothermal reserves in Indonesia, in a form of Joint Operation Contract (JOC) and gives incentives in fiscal and other terms to contractors that develop this source of energy. In the JOC, PERTAMINA is responsible for the management of operation and Contractor is responsible for the execution of the operation. Contractor has to provide financial, technical assistance and all facilities required to conduct geothermal operation and carries the risks of operating cost and therefore has an economic interest from the project. Each party involved in the development has a right to demand a certain portion of the Net Operating Income (NOI). The Energy Sales Contract (ESC) is made in conjunction with the JOC whereby the buyer agrees to purchase from PERTAMINA geothermal steam or electricity which is generated from geothermal energy produced and delivered by Contractor to the buyer on behalf of PERTAMINA.

    The developing nations of the Mideast, Far East, and Africa face a bleaker - and more-complicated - energy picture than that of the West. Rapid industrial and agricultural expansion in the region severely drains already-inadequate energy systems. Energy-importing countries find they must diversify and develop indigenous resources, but often lack the technical known-how to do so. Volume 1 is a compilation of official US government intelligence reports examining the way 22 countries in the Mideast, Far East, and Africa are responding to the energy problems. The countries covered are: Algeria, Australia, Burma, China, Egypt, Gabon, India, Indonesia, Ivory Coast, Japan, Korea, Kuwait, Lebanon, Morocco, Mozambique, Pakistan, Saudi Arabia, South Africa, Sudan, Taiwan, Tunisia and Turkey. The range and detail of country reports vary, due to availability of reports. Although the book details current energy situations, its main emphasis is on the future, including estimates of future production and consumption, and descriptions of energy development plans. Some of the countries in this region are fortunate to have petrochemical resources, while electric energy expansion is crucial to national development in all. Coal will be filling the gap left by diminishing oil supplies. 61 tables.

    Labor force interdependence creates a complex pattern among countries in the Middle East. Oil-rich countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) must import two-thirds of their labor force, including 80% of their professional and technical workers. These migrant workers come from Egypt (60%), Jordan, Yemen, Sudan, and South Asia, and the money they send home is a major factor in the economies of their native lands. Many Arabs who are considered foreign laborers have spent their entire lives, or have even been born, in the oil-rich countries; they have no hope of attaining citizenship. South Asians compete with Arabs for work in the Gulf States and tend to accept less-desirable jobs and lower wages. South Asian workers migrate from Bangladesh, India, Pakistan, Sri Lanka, Indonesia, Korea, the Philippines, and Thailand. Middle Eastern women have social constraints on labor force participation, and most of the women working n the Gulf States are Asian; they often work as domestics. The women of the Middle East are an untapped resource for this labor market. PMID:12286978

According to our estimation, there is an annual loss of US$18,673,495, US$13,641,021, and US$2,425,500 due to taeniasis in the mountainous areas of Taiwan, Cheju Island of Korea, and Samosir Island of Indonesia, respectively. Although taeniasis and cysticercosis due to Taenia solium have been reported, T. saginata asiatica is the dominate species in part of the world, especially in the mountainous and remote areas where the inhabitants are fond of eating raw or undercooked meat and/or viscera of domestic or wild animals. Therefore, sociocultural factors and local customs are the determinants in the transmission of taeniasis. In this paper, local customs and sociocultural factors including local dishes, accidental infection during dish preparation, and treatment for anaemia of children in the countries of East Asia were reviewed.

    Middle East respiratory syndrome (MERS) is a highly lethal respiratory disease caused by a novel single-stranded, positive-sense RNA betacoronavirus (MERS-CoV). Dromedary camels, hosts for MERS-CoV, are implicated in direct or indirect transmission to human beings, although the exact mode of transmission is unknown. The virus was first isolated from a patient who died from a severe respiratory illness in June, 2012, in Jeddah, Saudi Arabia. As of May 31, 2015, 1180 laboratory-confirmed cases (483 deaths; 40% mortality) have been reported to WHO. Both community-acquired and hospital-acquired cases have been reported with little human-to-human transmission reported in the community. Although most cases of MERS have occurred in Saudi Arabia and the United Arab Emirates, cases have been reported in Europe, the USA, and Asia in people who travelled from the Middle East or their contacts. Clinical features of MERS range from asymptomatic or mild disease to acute respiratory distress syndrome and multiorgan failure resulting in death, especially in individuals with underlying comorbidities. No specific drug treatment exists for MERS and infection prevention and control measures are crucial to prevent spread in health-care facilities. MERS-CoV continues to be an endemic, low-level public health threat. However, the virus could mutate to have increased interhuman transmissibility, increasing its pandemic potential.

    The intent of this paper is to give a basic overview presentation on Canada's east coast play - most likely the number one offshore play in the free world - and possibly the world. The play stretches 2,500 miles north and south, as it follows the Labrador Coast, past the Strait of Belle Isle and onto the Grand Banks of Newfoundland and as it makes a 90 degree turn, 1,000 miles east to west along the coast of Nova Scotia to the Georges Bank. 3,500 miles in all - which if placed in western Canada, would stretch from northern Alberta to southern Mexico. It's geologic potential is immense - 15-20 billion barrels of oil and 80-90 Tcf of natural gas. And so far only approximately 2 billion barrels of oil and 5 Tcf of natural gas have been found. There is more out there. And less than 200 wells have been drilled - still very virgin territory. Two world size discoveries have been made in the area. Hibernia, on the Grand Banks, is estimated to contain 1.8 billion barrels. Venture, on the Scotian Shelf, has a natural gas reserve of 2.5 Tcf - big by Canadian standards and significant in that Mobil Oil has also made some other interesting discoveries on the same Sable Island block which have not been delineated.

    Places where the earth's crust has formed deep fissures and the plates have begun to move apart develop rift structures in which elongate blocks have subsided relative to the blocks on either side. The East African Rift is a world-famous example of such rifting. It is characterized by 1) topographic deep valleys in the rift zone, 2) sheer escarpments along the faulted walls of the rift zone, 3) a chain of lakes within the rift, most of the lakes highly saline due to evaporation in the hot temperatures characteristic of climates near the equator, 4) voluminous amounts of volcanic rocks that have flowed from faults along the sides of the rift, and 5) volcanic cones where magma flow was most intense. This example in Kenya displays most of these features near Lake Begoria.

    Background Indonesia is the world’s fifth largest cigarette market in the world but for decades, transnational tobacco companies (TTCs) have had limited success infiltrating this market, due to their inability to compete in the kretek market. Kreteks are clove/tobacco cigarettes that most Indonesians smoke. Objective To determine how Phillip Morris International (PMI) and British American Tobacco (BAT) have now successfully achieved a substantial market presence in Indonesia. Methods We analyzed previously secret, tobacco industry documents, corporate reports on Indonesia operations, the Tobacco Trade press, Indonesia media, and “The Roadmap.” Results Internal, corporate documents from BAT and PMI demonstrate that they had known for decades that kreteks are highly carcinogenic. Despite that knowledge, BAT and PMI now own and heavily market these products, as well as new more westernized versions of kreteks. BAT and PMI maintained the basic strategy of keeping cigarettes affordable by maintaining the social responsibility of smoking and opposing smoke-free workplace laws but in the 21st century, they added the acquisition of and Westernization of domestic kretek manufacturers as an additional strategy. These acquisitions allowed them to assert influences on health policy in Indonesia and to grow their business under current government policy embodied in the 2007-2020 Roadmap of Tobacco Products Industry and Excise Policy which calls for increased cigarette production by 12% over the next 15 years. Conclusion PMI and Bat have successfully entered and are expanding their share in the Indonesia cigarette market. Despite the obvious and pervasive influence of the tobacco industry on policy decisions, the Indonesian government should ratify the FCTC and implement effective legislation to reduce tobacco consumption and exposure to tobacco smoke and revise the Roadmap to protect future generations of Indonesians.

  8. Medical care as the carrot: the Red Cross in Indonesia during the war of decolonization, 1945-1950.

    PubMed

    van Bergen, L

    2013-01-01

    During the war of decolonisation in Indonesia 1945-1950, the Dutch Red Cross and the Dutch East Indies Red Cross delivered aid to sick and wounded soldiers and civilians. This was supposed to happen in cooperation with organisations including the Indonesian Red Cross, the International Committee of the Red Cross, the military health service and civilian health services. Due to lack of resources, doctors and nurses, and due to differing interests, cooperation went anything but smoothly, severely undermining medical aid. On top of that, the aid that was given turned out be a tool of propaganda for the Dutch cause. Aid was deliberately--and with Red Cross consent--used as a political-military tool in the service of Dutch national interests. In a military strategy of carrot and stick, medical care served as the carrot.

    In Indonesia, an ongoing government "war on drugs" has resulted in numerous arrests and anecdotal reports of abuse in detention, but to date there has been little documentation or analysis of this issue. JANGKAR (also known in English as the Indonesian Harm Reduction Network), a nongovernmental organization (NGO) based in Jakarta, surveyed 1106 injecting drug users in 13 cities about their experiences of police abuse. Of those interviewed, 667 or 60% reported physical abuse by police. These findings indicate the importance of continuing efforts to promote police reform and harm reduction in Indonesia.

  10. East Candor Chasma

    NASA Technical Reports Server (NTRS)

    1997-01-01

    During its examination of Mars, the Viking 1 spacecraft returned images of Valles Marineris, a huge canyon system 5,000 km long, up to 240 km wide, and 6.5 km deep, whose connected chasma or valleys may have formed from a combination of erosional collapse and structural activity. The view shows east Candor Chasma, one of the connected valleys of Valles Marineris; north toward top of frame; for scale, the impact crater in upper right corner is 15 km (9 miles) wide. The image, centered at latitude 7.5 degrees S., longitude 67.5 degrees, is a composite of Viking 1 Orbiter high-resolution (about 80 m/pixel or picture element) images in black and white and low-resolution (about 250 m/pixel) images in color. The Viking 1 craft landed on Mars in July of 1976.

    East Candor Chasma occupies the eastern part of the large west-northwest-trending trough of Candor Chasma. This section is about 150 km wide. East Candor Chasma is bordered on the north and south by walled cliffs, most likely faults. The walls may have been dissected by landslides forming reentrants; one area on the north wall shows what appears to be landslide debris. Both walls show spur-and-gully morphology and smooth sections. In the lower part of the image northwest-trending, linear depressions on the plateau are younger graben or fault valleys that cut the south wall.

    Material central to the chasma shows layering in places and has been locally eroded by the wind to form flutes and ridges. These interior layered deposits have curvilinear reentrants carved into them, and in one locale a lobe flows away from the top of the interior deposit. The lobe may be mass-wasting deposits due to collapse of older interior deposits (Lucchitta, 1996, LPSC XXVII abs., p. 779- 780); this controversial idea requires that the older layered deposits were saturated with ice, perhaps from former lakes, and that young volcanism and/or tectonism melted the ice and made the material flow.

    An outbreak of dengue fever (DF), dengue haemorrhagic fever (DHF), and dengue shock syndrome (DSS) in the city of Palembang, south Sumatra, Indonesia was investigated to (i) validate epidemic occurrence, (ii) confirm dengue virus aetiology and associated serotype(s), (iii) provide a demonstrable measure of community impact, and (iv) identify causative relationship (if any) with climatic El Niño Southern Oscillation (ENSO) influences. Trend analysis based on a 6-year retrospective review of hospital records demonstrates a 3-fold increase in clinical cases for the outbreak period (January-April 1998), relative to historical records. In the 2 hospitals surveyed, the monthly mean number of outbreak-related dengue cases over 4 months was 833 (range 650-995 cases/month); the mean monthly value for the previous 72 months was 107 (range 14-779 cases/month). An apparent trend in epidemic transmission was observed, evolving from a 5-year cyclic phenomenon to an annual occurrence, often indistinguishable from one year to the next. The proportional distribution of clinical outbreak cases into DF, DHF and DSS diagnostic categories was 24%, 66%, and 10%, respectively. The population aged 10-19 years accounted for the largest (35%) proportion of hospitalized DHF cases, followed by children aged 5-9 years (25%) and children aged 4 years (16%). Serum samples obtained during acute illness from 221 hospitalized patients were examined using serology, RT-PCR, and virus isolation in cell culture: 59% of samples had laboratory evidence of a dengue infection. All 4 dengue virus serotypes (DEN 1-4) were identified in epidemic circulation, with DEN 3 predominating (43%). DEN 1 was the principal serotype associated with less severe dengue illness, suggesting that virulence may be, in part, a function of infecting serotype. The climatic influence of ENSO on rainfall and temperature in the months leading up to and during the outbreak was dramatic, and is likely to contribute to favourable

  12. Cleaner production: Minimizing hazardous waste in Indonesia

    SciTech Connect

    Bratasida, D.L.

    1996-12-31

    In the second long-term development plan, industry plays a significant role in economic growth. In Indonesia, industries grow very fast; such fast growth can adversely effect the environment. Exploitation of assets can mean depletion of natural resources and energy, which, if incorrectly managed, can endanger human life and the environment. The inefficient use of natural resources will accelerate their exhaustion and generate pollution, resulting in environmental damage and threats to economic development and human well being. In recent years, changes in the approach used to control pollution have been necessary because of the increasing seriousness of the problems. Initial environmental management strategies were based on a carrying capacity approach; the natural assimilative capacity accommodated the pollution load that was applied. The environmental management strategies adopted later included technologies applied to the end of the discharge point (so-called {open_quotes}end-of-pipe{close_quotes} treatments). Until now, environmental management strategies focused on end-of-pipe approaches that control pollutants after they are generated. These approaches concentrate on waste treatment and disposal to control pollution and environmental degradation. However, as industry develops, waste volumes continue to increase, thereby creating further environmental problems. In addition, the wastes produced tend to have more complex characteristics and are potentially more difficult to treat for a reasonable cost. There are often technical and financial obstacles to regulatory compliance if waste treatment is relied on as the only means of achieving environmental objectives. Consequently, the reactive end-of-pipe treatment approach has been changed to a proactive cleaner production approach. This approach is based on the concept of sustainable development and is designed to prevent pollution as well as to protect natural resources and the quality of the environment.

    The menopause is universal, but what about the climacteric? In an attempt to answer this question, a study was conducted in seven south-east Asian countries, namely, Hong Kong, Indonesia, Korea, Malaysia, the Philippines, Singapore and Taiwan. Samples of approximately 400 women in each country were questioned about a number of climacteric complaints, incontinence and dyspareunia, consultation of a physician, menopausal status and several background characteristics. Special care was taken to overcome linguistic and cultural problems, and the data collected were kept as objective as possible. From the results obtained we were able to show that the climacteric was indeed experienced in south-east Asian countries, although in a mild form. The prevalence of hot flushes and of sweating was lower than in western countries, but was nevertheless not negligible. The percentages of women who reported the more psychological types of complaint were similar to those in western countries. The occurrence of climacteric complaints affected perceived health status. A physician was consulted for climacteric complaints by 20% of the respondents, although this was most frequently associated with the occurrence of psychological complaints and less so with that of hot flushes and sweating. The median age at menopause (51.09) appeared to be within the ranges observed in western countries. Ethnic background and age at menarche were found to have a significant influence on age at menopause. The study clearly demonstrated that climacteric complaints occur in south-east Asia. The findings suggest, however, that vasomotor-complaint-related distress might be 'translated' into psychological complaints, which are more frequently considered to warrant consulting a physician.

    2016-01-01

    SUMMARY The Middle East Respiratory Syndrome (MERS) is a newly recognized highly lethal respiratory disease caused by a novel single stranded, positive sense RNA betacoronavirus (MERS-CoV). Dromedary camels, host species for MERS-CoV are implicated in the direct or indirect transmission to humans, although the exact mode of transmission remains unknown. First isolated from a patient who died from a severe respiratory illness in June 2012 in Jeddah, Saudi Arabia, as of 16 February 2015, 983 laboratory-confirmed cases of MERS-CoV (360 deaths; 36.6% mortality) were reported to the WHO. Cases have been acquired in both the community and hospitals with limited human-to-human transmission reported in the community. Whilst the majority of MERS cases have occurred in Saudi Arabia and the United Arab Emirates, cases have been reported from Europe, USA and Asia in people who traveled from the Middle East or their contacts. Clinical features of MERS range from asymptomatic or mild disease to acute respiratory distress syndrome and multi-organ failure resulting in death, especially in individuals with underlying co-morbidities. There is no specific drug treatment for MERS and infection prevention and control measures are crucial to prevent spread of MERS-CoV in health care facilities. MERS-CoV continues to be an endemic,low level public health threat. However, the concern remains that the virus could mutate to exhibit increased interhuman transmissibility, increasing pandemic potential. Our seminar presents an overview of current knowledge and perspectives on the epidemiology, virology, mode of transmission, pathogen-host responses, clinical features, diagnosis and development of new drugs and vaccines.

    2014-01-01

    Background The practice of sharing sanitation facilities does not meet the current World Health Organization/UNICEF definition for what is considered improved sanitation. Recommendations have been made to categorize shared sanitation as improved sanitation if security, user access, and other conditions can be assured, yet limited data exist on user preferences with respect to shared facilities. Objective This study analyzed user perceptions of shared sanitation facilities in rural households in East Java, Indonesia, and Bangladesh. Methods Cross-sectional studies of 2,087 households in East Java and 3,000 households in Bangladesh were conducted using questionnaires and observational methods. Relative risks were calculated to analyze associations between sanitation access and user perceptions of satisfaction, cleanliness, and safety. Results In East Java, 82.4% of households with private improved sanitation facilities reported feeling satisfied with their place of defecation compared to 68.3% of households with shared improved facilities [RR 1.19, 95% CI 1.09, 1.31]. In Bangladesh, 87.7% of households with private improved facilities reported feeling satisfied compared to 74.5% of households with shared improved facilities [RR 1.15, 95% CI 1.10, 1.20]. In East Java, 79.5% of households who reported a clean latrine also reported feeling satisfied with their place of defecation; only 38.9% of households who reported a dirty latrine also reported feeling satisfied [RR 1.74, 95% CI 1.45, 2.08]. Conclusion Simple distinctions between improved and unimproved sanitation facilities tend to misrepresent the variability observed among households sharing sanitation facilities. Our results suggest that private improved sanitation is consistently preferred over any other sanitation option. An increased number of users appeared to negatively affect toilet cleanliness, and lower levels of cleanliness were associated with lower levels of satisfaction. However, when sanitation

    1988-01-01

    Husband's approval of contraceptive use plays a decisive role in Indonesia. Despite this, no previous study of contraceptive use in Indonesia has evaluated the importance of husband's approval. Such evaluation is especially important in metropolitan areas where family planning programs have encountered more difficulty than those elsewhere in recruiting contraceptive users. Using data from the first Indonesia Contraceptive Prevalence Survey for metropolitan cities, husband's approval and other determinants of contraceptive use among fecund women were evaluated. The levels of contraceptive use varied among cities, ranging from 34.2 percent in Ujung Pandang to 56.5 percent in Semarang. For all cities, however, husband's approval was the most important determinant, followed by number of living children and wife's education. Among women who desire to have no more children, 17.4 percent and 27.8 percent of contraceptive nonuse in Medan and Jakarta, respectively, was attributable to husband's disapproval. Because most of the family planning programs in Indonesia are designed to serve primarily women, the finding of husband's approval as the most important determinant has important program implications.

    The introduction of pentavalent vaccine containing Haemophilus influenzae type b antigen in Indonesia’s National Immunization Program occurred nearly three decades after the vaccine was first available in the United States and 16 years after Indonesia added hepatitis B vaccine into the program. In this study, we analyzed the process that led to the decision to introduce pentavalent vaccine in Indonesia. Using process tracing and case comparison, we used qualitative data gathered through interviews with key informants and data extracted from written sources to identify four distinct but interrelated processes that were involved in the decision making: (a) pentavalent vaccine use policy process, (b) financing process, (c) domestic vaccine development process and (d) political process. We hypothesized that each process is associated with four necessary conditions that are jointly sufficient for the successful introduction of pentavalent vaccine in Indonesia, namely (a) an evidence-based vaccine use recommendation, (b) sufficient domestic financing capacity, (c) sufficient domestic vaccine manufacturing capacity and (d) political support for introduction. This analysis of four processes that led to the decision to introduce a new vaccine in Indonesia may help policy makers and other stakeholders understand and manage activities that can accelerate vaccine introduction in the future.

    PubMed

    Priosoeryanto, Bambang Pontjo; Arifiantini, Iis

    2014-01-01

    The beginning of the veterinary profession in Indonesia dates back to the middle of the 19th century. During the Dutch colonization period a development program for large ruminants was started by the 'Nederlandsch-Indië' government. In 1907 this government established a veterinary laboratory, planned by Dr. J.K.F. de Does. The laboratory was then merged with a veterinary training course for Indonesian (bumiputera) 'veterinarians' named 'Cursus tot Opleiding van Inlandsche Veeartsen'. In 1910 the name of the training course was changed to 'Inlandsche Veeartsenschool', and in 1914 the school was named 'Nederlandsch-Indische Veeartsenijschool' (NIVS). During the Japanese occupation (1942-1945) the veterinary school was named 'Bogor Semon Zui Gakko'. After the declaration of independence by Indonesia in August 1945, it became the High School of Veterinary Education. In 1946 the curriculum was extended from 4 to 5 years. Thereafter the school was closed and re-opened a few times due to the changing political circumstances. In 1947 the first Faculty of Veterinary Medicine ('Diergeneeskundige Faculteit') of the University of Indonesia was established in the former building of NIVS at Taman Kencana Campus in Bogor. Between 1948 and 1963, four more veterinary faculties were established in Indonesia: Gajah Mada, Syiahkuala, Airlangga and Udayana. The Indonesian Veterinary Medical Association (IVMA) was established on January 9, 1953. The membership now exceeds 20,000 veterinarians and the association has 15 special interest groups. Since 2008, five new faculties of veterinary medicine have been established, bringing the total to 10.

    Using published data about consumption, economic aspects, and legislation, this paper analyzes tobacco control in Indonesia, a major consumer and producer of tobacco products. Given its large population and smoking prevalence, Indonesia ranks fifth among countries with the highest tobacco consumption globally. Over 62% of Indonesian adult males smoke regularly, contributing to a growing burden of non-communicable diseases and enormous demands on the health care system. Tobacco control policies, however, have remained low on the political and public health agenda for many years. One reason was the contribution of tobacco to government revenues and employment, particularly in the industrial sector. But tobacco's importance in employment has fallen significantly since the 1970s from 38% of total manufacturing employment compared with 5.6% today. Widespread use of tobacco since the 1970s and the concomitant burden of non-communicable diseases have given rise to a more balanced view of the costs and benefits of tobacco production over the last decade. The first tobacco control regulation passed in 1999, succeeded by amendments in 2000 and 2003. Today, few restrictions exist on tobacco industry conduct, advertising, and promotion in Indonesia. We examine the relevance and prospects of advancing in Indonesia four cost-effective tobacco control strategies: price and tax measures, advertising bans, clean air legislation, and public education. We conclude with several suggestions for action for the public health community.

  1. Indonesia: a delicate balance between people and land.

    PubMed

    1981-12-01

    60% of Indonesia's approximately 148 million people live on the island of Java, which accounts for only 6% of Indonesia's total land area. Because of the alarming projected population growth increase by the year 2000, it is imperative that Java's population problems be approached with regard to the environment rather than urban planning alternatives. A rural family of 5 or 6 persons should have at least 3 quarters to 1 hectare of rice-filled land to live decently. Java's current situation precludes the use of any more land for urban purposes as it would reduce the amount of land available for food production. To maintain the delicate balance between human needs and nature, existing forests should be enlarged, extensive critical land areas restored, and rice fields maintained as they are now. It is estimated that a maximum of approximately 60 million people can live humanely in Indonesia's rural areas; if 126 million people will inhabit Java by 2000, 66 million will have to live in urban areas. This means being prepared for high density cities with all their implications and complications. Jakarta, Indonesia's capital city, has a current population of about 6.6 million people but is expected to grow to 9.7 million by 2001. Its annual growth rate is 4.5%, 42% of which results from in-migration from rural areas. In view of the projected population problems, rapid urbanization of Java appears to be more a solution rather than a problem.

    The eastern part of Indonesia covers approximately 3 million square kilometers, 35 percent being landmass and 65 percent covered by ocean. Only three of 38 sedimentary basins are producing hydrocarbon (Salawati, Bintuni, and Seram Basins). Oil and gas have discovered in the Lariang, Bone, Timor, Banggai, Sula and Biak Basins, however the discoveries have not developed yet. Hydrocarbon systems in Northern Australia and Papua New Guinea give the major contributions to the geological idea of Pre-Tertiary section in the less explored area in the Eastern Indonesia. The Triassic-Middle Jurassic marine carbonaceous shale sequences are the main hydrocarbon source rock in the Irian Jaya and surrounding area (Buton, gula and Seram basins). The main Mesozoic reservoir are the Kembelangan Formation in the Bintuni Basin of Irian Jaya and Bobong Formation in the North Sula Region. Exploration play types in the Eastern Indonesia can be divided into five types: 1 - Peri Cratonic, 2 - Marginal Rift Graben, 3 - Thrust Fold Belt Island Arc, 4 - Early Collision and 5 -Microcontinental Block - Advanced Collision. Recent discoveries through Mesozoic section in Eastern Indonesia are: Roabiba-1 (1990) in Bintuni Basin-Irian Jaya (Kambelangan Formation); Loku- 1 (1990) in North Sula region (Pre-Tertiary sediments); Oseil-1 (1993/94) in Bula-Seram Basin (Jurassic Manusela Formation); Elang-1 (1 994); Kakaktua-1 (1994) and Laminaria-1 in North Bonaparte Basin (Upper Jurassic Sands).

Additional discussion focuses on family planning methods, marriage patterns, fertility prospects, theories of fertility change, and policy implications for the labor supply, labor migrants, increased female participation in the labor force (LFP), human resource development, and social policy measures. Figures provide graphic descriptions of total fertility rates (TFRS) for 12 countries/areas for selected years between 1960-90, TFR for selected Chinese cities between 1955-90, the % of currently married women 15-44 years using contraception by main method for selected years and for 10 countries, actual and projected TFR and annual growth rates between 1990-2020 for Korea and Indonesia. It is noted that the 1st southeast Asian country to experience a revolution in reproductive behavior was Japan with below replacement level fertility by 1960. This was accomplished by massive postponement in age at marriage and rapid reduction in marital fertility. Fertility was controlled primarily through abortion. Thereafter every southeast Asian country experienced fertility declines. Hong Kong, Penang, Shanghai, Singapore, and Taipei and declining fertility before the major thrust of family planning (FP). Chinese fertility declines were reflected in the 1970s to the early 1980s and paralleled the longer, later, fewer campaign and policy which set ambitious targets which were strictly enforced at all levels of administration. Korea and Taiwan's declines were a result of individual decision making to restrict fertility which was encouraged by private and government programs to provide FP information and subsidized services.

    2016-03-01

    The variability of lightning flash and thunderstorm on the ENSO time scales over East/Southeast Asia was investigated by using 17-year (1995-2011) lightning data from the Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS), and 14-year (1998-2011) Tropical Rainfall Measuring Mission satellite (TRMM) precipitation feature data. In addition, ERA-Interim reanalysis data of the European Centre for Medium-Range Weather Forecasts (ECMWF) were used to present related environmental characteristics. It was found that the response of lightning flash to ENSO events shows remarkable seasonal and regional variations. The regions of positive (negative) lightning anomaly are mainly located at both sides of 5°-20°N (5°-15°N) in El Niño (La Niña) spring and winter, and located north of the equator in summer and autumn. There is a significantly positive correlation between lightning anomaly and the Oceanic Niño Index (ONI) over both East China and Indonesia during El Niño episodes, but no obvious correlation during La Niña episodes. The positive thunderstorm anomalies during El Niño periods are dispersed. The distribution of thunderstorm anomalies in La Niña summer and autumn is almost opposite to that in spring and winter. The correlation between thunderstorm anomaly and ONI is better over East China than that over Indonesia. In general, lightning variation follows thunderstorm intensity (number) variation over East China during El Niño (La Niña) episodes, and follows a combination of thunderstorm intensity and number variations over Indonesia on ENSO time scales. During ENSO time scales, variations of surface wind can be considered as one of the key factors to LAs. More lightning flashes present in the regions where warm moist flows intersection, and less in the regions where surface wind changes slightly or diverges. Dramatic lightning increases also occur with higher values of convective available potential energy (CAPE). In addition, higher (lower

    Micronutrient deficiency remains a serious problem in Indonesia with approximately 100 million people, or 40% of the population, suffering from one or more micronutrient deficiencies. In rural areas with poor market access, forests and trees may provide an essential source of nutritious food. This is especially important to understand at a time when forests and other tree-based systems in Indonesia are being lost at unprecedented rates. We use food consumption data from the 2003 Indonesia Demographic Health Survey for children between the ages of one and five years and data on vegetation cover from the Indonesian Ministry of Forestry to examine whether there is a relationship between different tree-dominated land classes and consumption of micronutrient-rich foods across the archipelago. We run our models on the aggregate sample which includes over 3000 observations from 25 provinces across Indonesia as well as on sub-samples from different provinces chosen to represent the different land classes. The results show that different tree-dominated land classes were associated with the dietary quality of people living within them in the provinces where they were dominant. Areas of swidden/agroforestry, natural forest, timber and agricultural tree crop plantations were all associated with more frequent consumption of food groups rich in micronutrients in the areas where these were important land classes. The swidden/agroforestry land class was the landscape associated with more frequent consumption of the largest number of micronutrient rich food groups. Further research needs to be done to establish what the mechanisms are that underlie these associations. Swidden cultivation in is often viewed as a backward practice that is an impediment to food security in Indonesia and destructive of the environment. If further research corroborates that swidden farming actually results in better nutrition than the practices that replace it, Indonesian policy makers may need to

    1993-12-01

    This paper describes the case of a middle-class woman in Indonesia who travels 60 kilometers to receive family planning services instead of going to a locally-based private or public facility. She is a long-term IUD-using mother with children aged 18, 15, and 6 years who attends a private Yayasan Kusuma Buana (YKB) clinic in northern Jakarta. YKB is an independent nongovernmental organization (NGO) which promotes private sector involvement in urban family planning in Indonesia. Its 6 clinics served an estimated 9284 acceptors in 1993. Two clinics are self- sufficient, one is almost, and the rest should be within a few years. The case described reflects a trend in Indonesia of women increasingly seeking fee-based family planning services. While 20% of family planning acceptors now use family planning services provided by the private sector and NGOs in Indonesia, only 12% did so 6 years ago. Purely free family planning services are quickly disappearing in Indonesia. The National Family Planning Coordinating Board encourages this trend. Friendly and competent female midwives and support staff; short waiting times; the absence of sick and injured patients; bright and clean atmospheres; and affordable prices at YKB clinics attract and hold clients. YKB also promotes various community-based health programs such as the fee-charging school health program in Jakarta since 1987. Further, the organization has offered technical assistance to other private/NGO groups who wish to replicate similar programs elsewhere. The Executive Director notes in closing that maternal and child health services should account for an ever larger share of YKB services over time.

    2004-05-01

    Since the 1994 International Conference on Population and Development, the need for sexuality education for youth has been articulated, and numerous activities in Indonesia, especially Java, have been directed at young people. However, many parents, teachers and religious leaders have considered it essential that such education should suppress youth sexuality. This article reflects upon current discourses on youth sexuality in Java as against the actual sexual behaviour of young people. Using examples from popular magazines and educational publications, and focus group discussions with young men and women in Surabaya, East Java, we argue that the dominant prohibitive discourse in Java denounces youth sexuality as unhealthy, reinforced through intimidation about the dangers of sex. In contrast, a discourse of competence and citizenship would more adequately reflect the actual sexual behaviour of youth, and raises new challenges for sexuality education. Information should be available to youth concerning different sexualities, respecting the spectrum of diversity. Popular youth media have an especially important role to play in this. The means to stay healthy and be responsible--contraceptives and condoms--should be available at sites where youth feel comfortable about accessing them. Meanwhile, young Indonesians are engaging in different forms of sexual relationships and finding their own sources of information, independent of government, religion and international organisations.

    The Sumba Island lies in a key area to study the eastern Indonesia geodynamics. It is located in the Sunda-Banda fore-arc in the area of transition from subduction of the Indian oceanic lithosphere (W) beneath the Sunda-Banda arc to arc-continent collision between the Australian continental margin and the Sunda-Banda arc (E). East of the Sumba Island, the western boundary of the Savu basin originated during Middle Miocene by the southeastward slab retreat below the Sunda-Banda arc (Rigg and Hall, 2001). Previous studies has detected a global uplift of the island accommodating the Australian plate - South West Banda Arc convergence (Fleury et al., 2009). This uplift is associated with northeastward tilting and gravitational collapse to the South. Analyses of various geomorphic markers (perched low relief landscapes, rockyshore platform, coral reef terraces, drainages) and of morphometric indices allowed us to localise new structures (faults and folds), to determine the chronology of their activation and to better constraint the uplift history of Sumba Island. These results aim to understand the evolution of the deformation in Sumba Island in regard with its geodynamic context from Middle Miocene to present-day.

    Sangiran (Solo Basin, Central Java, Indonesia) is the singular Homo erectus fossil locale for Early Pleistocene Southeast Asia. Sangiran is the source for more than 80 specimens in deposits with (40)Ar/(39)Ar ages of 1.51-0.9 Ma. In April 2001, we recovered a H. erectus left maxilla fragment (preserving P(3)- M(2)) from the Sangiran site of Bapang. The find spot lies at the base of the Bapang Formation type section in cemented gravelly sands traditionally called the Grenzbank Zone. Two meters above the find spot, pumice hornblende has produced an (40)Ar/(39)Ar age of 1.51 ± 0.08 Ma. With the addition of Bpg 2001.04, Sangiran now has five H. erectus maxillae. We compare the new maxilla with homologs representing Sangiran H. erectus, Zhoukoudian H. erectus, Western H. erectus (pooled African and Georgian specimens), and Homo habilis. Greatest contrast is with the Zhoukoudian maxillae, which appear to exhibit a derived pattern of premolar-molar relationships compared to Western and Sangiran H. erectus. The dental patterns suggest distinct demic origins for the earlier H. erectus populations represented at Sangiran and the later population represented at Zhoukoudian. These two east Asian populations, separated by 5000 km and nearly 800 k.yr., may have had separate origins from different African/west Eurasian populations.

  17. Indonesia: government plans to speed up transmigration; analysis transmigration program.

    PubMed

    The Indonesian government plans to resettle 2.5 million people during the current Third Five-Year Development Plan (1979-84). The plan involves round-the-clock shuttle flights from overcrowded Java to the neighboring and relatively empty islands. The government recently purchased 3 wide-bodied planes to ferry migrants to new homes in Sumatra, Kalimantan, Sulawesi, and West Irian. Some 500,000 people should have been resettled by last March, but because of lack of land preparation, only 16,000 families (as opposed to 100,000) could be relocated. The implementation of the plan would bring about 1 million ha of land into agricultural production. The program will cost about $2,500 million, but it is the only solution to Java, Bali, and Madura's population problems and food shortages. The Indonesian archipelago stretches over 5,150 kilometers and is composed of 13,680 tropical islands with a land territory of 1.92 million square kilometers. The population of 142 million is not spread evenly. 70% of the population is crowded onto about 7% of te terrirory. At present there are far more applicants for tranmigration than available new houses and prepared resettlements.

    This discussion of population focuses on the regions of Africa and the Middle East. In South Africa more white women are working but fewer black women work. The overall result is that the percentage of women who work is declining. Marita de Beer, research liaison executive at the South African Advertising Research Foundation, reports that the female population grew by 31% in the past 10 years while the number of working women has grown by only 11%. Among blacks the female population rose by 36%, but the number of workers among them declined by about 1%. Married women are among the fastest growing groups of working women in South Africa. The most recent estimate of the population of Nigeria is 92 million. According to Professor Vremudia Diejomaoh, Nigeria's population will probably reach 155 million by 2000 with 33% living in urban areas. In Saudi Arabia the Pan Arab Research Center recently completed a census of retail outlets in 3 metropolitan areas: Jeddah, Riyadh, and Dammam. The types of outlets surveyed include large supermarkets, small supermarkets, groceries with and without deep freeze, tobacco shops, meat shop/delis, small cafeterias, large restaurants/hotels, cosmetics shops or perfumeries, camera stores, toy shops, pharmacies, watch and gift shop, newsstands, department store, and appliance outlets.

    This discussion of population focuses on the regions of Africa and the Middle East. In South Africa more white women are working but fewer black women work. The overall result is that the percentage of women who work is declining. Marita de Beer, research liaison executive at the South African Advertising Research Foundation, reports that the female population grew by 31% in the past 10 years while the number of working women has grown by only 11%. Among blacks the female population rose by 36%, but the number of workers among them declined by about 1%. Married women are among the fastest growing groups of working women in South Africa. The most recent estimate of the population of Nigeria is 92 million. According to Professor Vremudia Diejomaoh, Nigeria's population will probably reach 155 million by 2000 with 33% living in urban areas. In Saudi Arabia the Pan Arab Research Center recently completed a census of retail outlets in 3 metropolitan areas: Jeddah, Riyadh, and Dammam. The types of outlets surveyed include large supermarkets, small supermarkets, groceries with and without deep freeze, tobacco shops, meat shop/delis, small cafeterias, large restaurants/hotels, cosmetics shops or perfumeries, camera stores, toy shops, pharmacies, watch and gift shop, newsstands, department store, and appliance outlets.

    Some aspects of mobility behavior were examined within a group of Indonesian village areas. Specifically, the objectives were to investigate for samples of residents the characteristics and locations of extra village employment; the nature of select short, repetitive trip activities with respect to frequency, distance, and mode of travel; and the characteristics of transport ownership and usage in the mobility behavior. The characteristics of contact and movement behavior were compared between a group of villages located on the fringe of large urban areas and another more rural and remote group of villages. Movement behavior was examined in conjunction with and as a possible impact of improved and new rural feeder road construction under the Cash Incentive Rural Works Program of the Indonesia government. The data were obtained from interviews at households in the immediate hinterlands of the feeder road improvements. The selected households were all located within 3 kilometers of the road projects, for few residences were found beyond this distance in the various areas. Proximity to an urban area did not greatly influence the total number of individuals who had obtained outside employment, for the totals were quite similar. And there was no evidence to support the idea that the kotamadya with the largest population in the urban fringe groups had drawn more rural individuals in search of employment opportunities than those kotamadya with smaller proportions. The data did show that many more individuals in the urban fringe groups tended to seek employment either in the nearest kotamadya or other large cities. Nearly 50% in the urban fringe groups working outside found employment in various kotamadya whereas, on the average, only 25% in the more remote, rural groups did so. In general, the information gathered reveals that extravillage employment is quite low in these very poor areas and that, rather than size of city, the information about those opportunities in

    Indonesia has participated in cooperative technical programs with the IAEA since 1957, and has cooperated with regional partners in all of the traditional areas where nuclear science is employed: in medicine, public health (such as insect control and eradication programs), agriculture (e.g. development of improved varieties of rice), and the gas and oil industries. Recently, Indonesia has contributed significantly to the Reduced Enrichment Research and Training Reactor (RERTR) Program by conducting experiments to confirm the feasibility of Mo-99 production using high-density low enriched uranium (LEU) fuel, a primary goal of the RERTR Program. Indonesia's first research reactor, the TRIGA Mark II at Bandung, began operation in 1964 at 250 kW and was subsequently upgraded in 1971 to 1 MW and further upgraded in 2000 to 2 MW. This reactor was joined by another TRIGA Mark II, the 100-kW Kartini-PPNY at Yogyakarta, in 1979, and by the 30-MW G.A. Siwabessy multipurpose reactor in Serpong, which achieved criticality in July 1983. A 10-MW radioisotope production reactor, to be called the RPI-10, also was proposed for construction at Serpong in the late 1990s, but the project apparently was not carried out. In the five decades since its nuclear research program began, Indonesia has trained a cadre of scientific and technical staff who not only operate and conduct research with the current facilities, but also represent the nucleus of a skilled labor pool to support development of a nuclear power program. Although Indonesia's previous on-again, off-again consideration of nuclear power has not gotten very far in the past, it now appears that Indonesia again is giving serious consideration to beginning a national nuclear energy program. In June 2006, Research and Technology Minister Kusmayanto Kadiman said that his ministry was currently putting the necessary procedures in place to speed up the project to acquire a nuclear power plant, indicating that, ''We will need around

    Archaeologists have long been puzzled by the appearance in Europe ∼40-35 thousand years (kyr) ago of a rich corpus of sophisticated artworks, including parietal art (that is, paintings, drawings and engravings on immobile rock surfaces) and portable art (for example, carved figurines), and the absence or scarcity of equivalent, well-dated evidence elsewhere, especially along early human migration routes in South Asia and the Far East, including Wallacea and Australia, where modern humans (Homo sapiens) were established by 50 kyr ago. Here, using uranium-series dating of coralloid speleothems directly associated with 12 human hand stencils and two figurative animal depictions from seven cave sites in the Maros karsts of Sulawesi, we show that rock art traditions on this Indonesian island are at least compatible in age with the oldest European art. The earliest dated image from Maros, with a minimum age of 39.9 kyr, is now the oldest known hand stencil in the world. In addition, a painting of a babirusa ('pig-deer') made at least 35.4 kyr ago is among the earliest dated figurative depictions worldwide, if not the earliest one. Among the implications, it can now be demonstrated that humans were producing rock art by ∼40 kyr ago at opposite ends of the Pleistocene Eurasian world. PMID:25297435

  8. Variations in Organic Matter Burial and Composition in Sediments from the Indian Ocean Continental Margin Off SW Indonesia (Sumatra - Java - Flores) Since the Last Glacial Maximum

    Global climate change is a mosaic of regional changes to a large extent determined by region-specific feedbacks between climate and ecosystems. At present the ocean is forming a major sink in the global carbon cycle. Organic matter (OM) storage in sediments displays large regional variations and varied over time during the Quaternary. Upwelling regions are sites of high primary productivity and major depocenters of organic carbon (OC), the least understood of which is the Indian Ocean upwelling off Indonesia. In order to reconstruct the burial and composition of OM during the Late Quaternary, we analyzed five sediment cores from the Indian Ocean continental margin off the Indonesian islands Sumatra to Flores spanning the last 20,000 years (20 kyr). Sediments were analyzed for bulk composition, stable carbon and nitrogen isotopes of OM, amino acids and hexosamines and terrestrial plant wax n-alkanes and their stable carbon isotope composition. Sedimentation rates hardly varied over time in the western part of the transect. They were slightly lower in the East during the Last Glacial Maximum (LGM) and deglaciation, but increased strongly during the Holocene. The amount and composition of OM was similar along the transect with maximum values during the deglaciation and the late Holocene. High biogenic opal covarying with OM content indicates upwelling-induced primary productivity dominated by diatoms to be a major control of OM burial in sediments in the East during the past 20 kyr. The content of labile OM was low throughout the transect during the LGM and increased during the late Holocene. The increase was stronger and the OM less degraded in the East than in the West indicating that continental margin sediments off Java and Flores were the major depocenter of OC burial along the Indian Ocean margin off SW Indonesia. Temporal variations probably resulted from changes in upwelling intensity and terrestrial inputs driven by variations in monsoon strength.

    Precipitation in the Indonesian archipelago has varied significantly over the past millennium and is highly susceptible to future changes in atmospheric greenhouse gas concentrations. Modern studies reveal considerable spatial complexity in Indonesian precipitation and isotopes of precipitation, with strong teleconnections to large-scale tropical circulation patterns related to the Walker circulation, the Intertropical Convergence Zone (ITCZ), and regional monsoons. However, a paucity of continental precipitation proxy reconstructions and limited 20th century observations have lead to large uncertainties in Indonesian rainfall history, particularly on multi-decadal to centennial timescales, making the interactions among these mechanisms unclear. Stable isotopes in Indonesian precipitation reflect moisture source, transport, and rainfall amount, and thus provide a useful tool for discerning past and present circulation patterns. We present a new, decadally-resolved reconstruction of precipitation δD (δDprecip) from Lake Towuti, Sulawesi, central Indonesia. This reconstruction is based on the δD of terrestrial plant wax compounds (δDwax) preserved in the lake's sediments. We find ~30‰ variation in δDwax during the past 500 years in Sulawesi, with pronounced variability during the late Little Ice Age and significant D-enrichment, implying drying, during the late 19th and 20th centuries. We compare these findings to a recent, high-resolution δDwax record from Java, western Indonesia, where precipitation has steadily intensified over the past millennium, including the 20th century. Differences between Java and Sulawesi starting in the mid-19th century, as well as heterogeneity within other continental proxy reconstructions from the Indo-Pacific and East Africa, suggest that considerable spatial complexity in Indonesian precipitation has persisted for at least several centuries. As with modern precipitation, this complexity is likely due to regionally diverse

  10. Major earthquakes and tsunami of the Banda Arc region, Indonesia: the past 400 years

    Dutch historical records document several large earthquakes and tsunami throughout eastern Indonesia that we use to assess geophysical hazards in this densely populated region. For example, a large earthquake in 1629 generated a tsunami at least 15 m high. The first wave arrived at Banda Neira 30 minuets after violent shaking ceased. The event was followed by at least 8 years of aftershocks and other strong earthquakes over the next few decades. These data are consistent with a mega-thrust earthquake of Mw > 8.8 on the Seram Trough to the east or a >Mw 9.0 earthquake on the Timor-Tanimbar Trough to the south. Smaller tsunami from regional earthquakes that inflicted heavy damage throughout the Banda Arc is also documented in 1648, 1672, 1674 (2 m wave), 1710, 1754, 1778, 1802, 1820 (>20 m wave), 1835, 1836 (wave) and 1852 (8 m wave). These events are likely associated with earthquake activity along the thrust front of the collision zone or along a developing thrust system in the back arc. For example, the > 20 m wave from the 1820 event struck SE Sulawesi after 2-4 minuets of violent shaking throughout a region spanning over 1000 km. The most likely source for this event is the Flores Thrust, which produced a much smaller tsunami from a Mw 7.8 earthquake in 1992. However, the 1820 event is most likely > Mw 8.5 to produce a tsunami as large as the one recorded, 17 years of aftershocks and two possible related nearby volcanic eruptions. Since the seismic drama of 1629-1852, only one earthquake of > Mw 8 is documented in the Banda Arc region, and it was not along the subduction zone interface (Okal and Reymond, 2003). During this time of relative seismic quiescence at least 11 m of strain has accumulated across the active Banda arc-continent collision. A similar scenario is currently playing out in western Indonesia where Dutch records proved extremely reliable in documenting several mega-thrust earthquakes during the 18th and 19th centuries that are reoccurring and

    Preliminary deformation model for the Indonesia's National Seismic Hazard (NSH) map is constructed as the block rotation and strain accumulation function at the elastic half-space. Deformation due to rigid body motion is estimated by rotating six tectonic blocks in Indonesia. The interseismic deformation due to subduction is estimated by assuming coupling on subduction interface while deformation at active fault is calculated by assuming each of the fault`s segment slips beneath a locking depth or in combination with creeping in a shallower part. This research shows that rigid body motion dominates the deformation pattern with magnitude more than 15 mm/year, except in the narrow area near subduction zones and active faults where significant deformation reach to 25 mm/year.

    The introduction of the rotavirus vaccine in Indonesia is currently in its infancy. Delay in its development might be caused by factors related to the perceived value of the vaccine, health system characteristics and policy considerations. Other factors, which may also interfere with optimizing the introduction, are financial barriers because Indonesia is a lower-middle-income country. Creating fiscal space to finance new immunization programs, such as for the rotavirus immunization, is very important to ensure the sustainability of new programs so that such programs would be financed over the long term and not endanger the sustainability of the Indonesian government's financial position. This article provides an illustration of the various steps needed to accelerate the introduction of the rotavirus immunization.

    In this study, patterns of Norplant use in Indonesia are reviewed to assess the implications of this experience for the introduction of new contraceptive methods. Data from the Norplant Use-Dynamics Study and the 1994 Indonesia Demographic and Health Survey are analyzed, and patterns of acceptance, continuation, and removal are described. Acceptance of Norplant has increased steadily since it was first introduced. The method is now used by more than 5 percent of all married women of reproductive age. Continuation rates among Norplant users are higher than among users of the IUD. One factor behind high continuation rates may be that a substantial proportion of acceptors were not told that removal before five years was possible. Results indicate that deficits occurred in the quality of service delivery and that a need exists for improved provider training, better supervision, and clearer and better-enforced guidelines regarding women's right to have Norplant removed on demand.

    Monsoon droughts, which often coincide with El Niño warm events, can have profound impacts on the populations of Southeast Asia. Improved understanding and prediction of such events can be aided by high-resolution proxy climate records, but these are scarce for the tropics. Here we reconstruct the boreal autumn (October-November) Palmer Drought Severity Index (PDSI) for Java, Indonesia (1787-1988). This reconstruction is based on nine ring-width chronologies derived from living teak trees growing on the islands of Java and Sulawesi, and one coral δ18O series from Lombok. The PDSI reconstruction correlates significantly with El Niño-Southern Oscillation (ENSO)-related sea surface temperatures and other historical and instrumental records of tropical climate, reflecting the strong coupling between the climate of Indonesia and the large scale tropical Indo-Pacific climate system.

  19. Assessment of undiscovered conventionally recoverable petroleum resources of Indonesia

    The estimates of undiscovered conventionally recoverable petroleum in Indonesia at probability levels of 95 percent, 5 percent, and statistical mean are for oil (in billions of barrels): 5, 35, and 16; and for gas (in trillions of cubic feet): 13, 94, and 42. In Indonesia, petroleum occurs in five types of basins: forearc, back-arc (foreland), median, inner-arc, and downwarp into-small-ocean basins. The back-arc, median, and downwarp basins have significantly greater petroleum potential than do the fore-arc and inner-are basins. The latter two types are expected to yield only small discoveries; also, significant portions of such basins lie in water depths in excess of 1,000 m. The back-arc basins have been the most petroleum productive, but they also have been the most extensively explored. The greatest undiscovered petroleum potential is estimated to lie in the downwarp and median basins. In Indonesia, six general types of geological settings or plays have been identified as being favorable for petroleum accumulation. They are transgressive clastic sequences, regressive clastic sequences, deltas, carbonate platforms, pinnacle reefs, and fractured igneous and volcanic rocks. The multiple-pay transgressive clastic reservoirs in the back-arc basins have produced most of Indonesia's crude oil. In several basins, carbonate platform porosity has become a primary exploration target, but each reservoir (reef, bank, or bioclastic zone) tends to be restricted in size. Typically, Indonesian oil is of medium gravity with a paraffin base and has a moderate to high pour point, a low sulfur content, and a relatively low gas to oil ratio.

    Bats are an important natural reservoir for a variety of viral pathogens, including polyomaviruses (PyVs). The aims of this study were: (i) to determine which PyVs are present in bats in Indonesia and (ii) to analyze the evolutionary relationships between bat PyVs and other known PyVs. Using broad-spectrum polymerase chain reaction (PCR)-based assays, we screened PyV DNA isolated from spleen samples from 82 wild fruit bats captured in Indonesia. Fragments of the PyV genome were detected in 10 of the 82 spleen samples screened, and eight full-length viral genome sequences were obtained using an inverse PCR method. A phylogenetic analysis of eight whole viral genome sequences showed that BatPyVs form two distinct genetic clusters within the proposed genus Orthopolyomavirus that are genetically different from previously described BatPyVs. Interestingly, one group of BatPyVs is genetically related to the primate PyVs, including human PyV9 and trichodysplasia spinulosa-associated PyV. This study has identified the presence of novel PyVs in fruit bats in Indonesia and provides genetic information about these BatPyVs.

  1. Structural change and higher educated labour in Indonesia.

    PubMed

    Pasay, N H

    1990-12-01

    This paper describes an impending shortage of higher-educated labor in Indonesia. Dynamic change is occurring in both Indonesia's population and economy. Its rapidly growing population demands annual national economic growth of 2.2% to avoid declining per capita output. Accordingly, investments have surged in banking and manufacturing industries as Indonesia undergoes structural change from an agricultural to service-based economy. Plagued by a majority of low productivity, elementary-level educated workers, increased productivity is called for to ensure continued development. As the age structural shift progresses, many of these workers will be absorbed in the services sector. Jobs exist requiring workers of all skill levels. This paper is mainly concerned, however, with higher-educated labor's failure to be oriented to the research and development required for sustained economic growth and development, and their entry into clerical positions potentially filled by less educated and less skilled labor. The services sector, particularly public services, is responsible for absorbing much of this labor. As professional, technical, and managerial capabilities and qualifications become increasingly needed in the near future as sector investments take effect, a shortage of higher-educated labor will become apparent. Policy makers are advised to anticipate these shortages and contemplate investments in human capital to facilitate a more smooth adjustment to structural change. PMID:12343084

    The variation of ocean acidity (pH) in the Indonesia waters is strongly influenced by monsoon. Since the climate change tends to potentially change monsoonal variation over the Indonesian region, it will give also implication to the ocean pH variation. Moreover, changes of ocean pH will give effects to the marine lifes and their environment. In order to investigate this issue, we tried to calculate monthly variation of sea surface pH in the Indonesia waters based on monthly average temperature and salinity over past 18 years data. Temperature and salinity data used in this study were taken from the hydrodynamic model of Hamburg Shelf Ocean Model (HAMSOM), while alkalinity and dissolved inorganic carbon (DIC) were from World Ocean Atlas 2009 (WOA 2009). Algorithm from Ocean Carbon Model Intercomparison Project-version.3 (OCMIP-3) was used to calculate the pH. The estimation results indicate that pH variation in the Indonesia waters changes insignificantly over 18 years. El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) contribute to physical changes of seawater, but did not affect the pH significantly. The average pH of seawater is higher during northwest monsoon than during southeast monsoon.

    Indonesia is predicted to face a severe AIDS epidemic in the near future. More than 60% of the reported HIV-positive cases in Indonesia can be attributed to heterosexual transmission; therefore, by the nature of their work, female commercial sex workers (FCSWs) constitute one of the communities at risk. No meaningful or effective STD/HIV prevention programs for FCSWs can be planned if there is no contextual understanding of these women as persons, the nature and the risks of their job and their relations with their clients and managers. Just as it is incorrect to assume that all women enter prostitution for the same reasons, educational approaches that are modeled on shallow stereotypes will be ineffective. Interweaving qualitative and quantitative methods, this research investigates the FCSWs in an 'official' brothel complex in Jakarta, Indonesia. Results of this study give insights of four typologies of FCSWs observed in Kramat Tunggak. The personal, professional, social and other differences which influenced the women into full-time sex work and affected their willingness and ability to engage in healthy and protective behaviors, are presented. Finally, based on those findings a recommendation on how to deliver health messages to the FCSWs is offered.

    Indonesia and Australia are close neighbours sharing agro-ecological zones and common parasitological interests. Australia is an industrialised country and Indonesia is both industrialising and a developing country. The types of collaboration, contractual, collegiate, research collaboration and partnerships are briefly described. All forms of collaboration have and continue to exist between Australia and Indonesia. A survey of mammalian parasitology publications over the last 23 years indicates that the bulk of papers have been by Indonesian and non-Australian authors. Australian and Indonesian authors provided 4% of the total number of publications. The rational for collaboration is suggested to be the high degree of common multiple interests and the synergy of effort that can be derived from research partnerships. The most difficult issues in research collaboration are establishing the research priorities and, to a lesser extent, funding. The globalisation of the international research centre, International Livestock Research Institute, to include Asia will expand the opportunities for research collaboration. Details of the Australian Centre for International Agricultural Research mandate in supporting parasitology research collaboration is briefly described. The past and current research collaborative activities are reviewed and opportunities for future collaboration are listed.

    The main aim of this study is to overview the past and present situations of human taeniases and cysticercosis in Indonesia and including future perspectives. Through joint projects from 1996, we have confirmed the occurrence of Taenia saginata (beef tapeworm) in Bali, of Taenia solium (pork tapeworm) mainly in Papua and sporadically in Bali, and of Taenia asiatica in North Sumatra. These taeniases were caused through eating uncooked pork and pig viscera for T. solium and T. asiatica, respectively, and beef for T. saginata. The distribution of these tapeworms in Indonesia is basically highly restricted by the traditional cultural and religious backgrounds in each island. T. saginata is relatively common in Bali although people consume pork 'lawar' more than beef 'lawar'. Taeniases due to T. saginata or T. asiatica and T. solium and cysticercosis due to T. solium have also been sporadically reported in some other islands. Among these species, T. solium is exceptional since humans can be infected not only by larval stages (cysticerci) in pork but also by eggs released from human tapeworm carriers. Cysticercosis has been confirmed in Indonesia in humans, pigs and even dogs. PMID:23965293

    Indonesia is one of the 10 most populous countries in the world and is highly vulnerable to (river) flooding. Catastrophic floods occur on a regular basis; total estimated damages were US 0.8 bn in 2010 and US 3 bn in 2013. Large parts of Greater Jakarta, the capital city, are annually subject to flooding. Flood risks (i.e. the product of hazard, exposure and vulnerability) are increasing due to rapid increases in exposure, such as strong population growth and ongoing economic development. The increase in risk may also be amplified by increasing flood hazards, such as increasing flood frequency and intensity due to climate change and land subsidence. The implementation of adaptation measures, such as the construction of dykes and strategic urban planning, may counteract these increasing trends. However, despite its importance for adaptation planning, a comprehensive assessment of current and future flood risk in Indonesia is lacking. This contribution addresses this issue and aims to provide insight into how socio-economic trends and climate change projections may shape future flood risks in Indonesia. Flood risk were calculated using an adapted version of the GLOFRIS global flood risk assessment model. Using this approach, we produced probabilistic maps of flood risks (i.e. annual expected damage) at a resolution of 30"x30" (ca. 1km x 1km at the equator). To represent flood exposure, we produced probabilistic projections of urban growth in a Monte-Carlo fashion based on probability density functions of projected population and GDP values for 2030. To represent flood hazard, inundation maps were computed using the hydrological-hydraulic component of GLOFRIS. These maps show flood inundation extent and depth for several return periods and were produced for several combinations of GCMs and future socioeconomic scenarios. Finally, the implementation of different adaptation strategies was incorporated into the model to explore to what extent adaptation may be able to

    Both countries face considerable challenges to their rehabilitation services. Although contextually different, the problems and challenges are common to both. Two contrasting views of disability have been presented. In the UK disability may be viewed as a disaster, while in Asia illness and disability may be viewed as inevitable. Personal independence is not a universal goal of rehabilitation, because in some cultures dependence on others is an expected consequence of disability. Disability in Indonesia translates into a large burden of care for the family, whereas English families may expect greater help from the government in caring for their relative. Western rehabilitation is increasingly patient directed, whereas the Indonesian model is more likely to be determined solely by professionals. The problems observed by the team in Indonesia were remarkably similar to those experienced in the UK. A patient centered goal setting approach can be considered vital to neurological rehabilitation, although the focus of the goals set is likely to be very different in these two cultures. The fundamental importance of a multidisciplinary team is recognized in both cultures, although team working may not be easy in either situation. Managerial commitment is essential for the survival of a team, yet both structures sometimes fail to provide the necessary support. Hierarchical leadership can inhibit team development both in the UK and in Indonesia, as can frequent rotation of staff. Prescription of therapy by doctors inhibits the development of therapists in both cultures, and therefore the overall effectiveness of the team. In both the UK and Indonesia, the value of rehabilitation as a specialty is not widely recognized. The absence of life and death situations means that services are often out of the public eye, and poorly understood. However, the prevalence of disability will increase the need for rehabilitation services worldwide. Many challenges remain in both the UK and

    The aim of this study was to analyse the contemporary policies regarding avian and human pandemic influenza control in three South-East Asia countries: Thailand, Indonesia and Vietnam. An analysis of poultry vaccination policy was used to explore the broader policy of influenza A H5N1 control in the region. The policy of antiviral stockpiling with oseltamivir, a scarce regional resource, was used to explore human pandemic influenza preparedness policy. Several policy analysis theories were applied to analyse the debate on the use of vaccination for poultry and stockpiling of antiviral drugs in each country case study. We conducted a comparative analysis across emergent themes. The study found that whilst Indonesia and Vietnam introduced poultry vaccination programmes, Thailand rejected this policy approach. By contrast, all three countries adopted similar strategic policies for antiviral stockpiling in preparation. In relation to highly pathogenic avian influenza, economic imperatives are of critical importance. Whilst Thailand's poultry industry is large and principally an export economy, Vietnam's and Indonesia's are for domestic consumption. The introduction of a poultry vaccination policy in Thailand would have threatened its potential to trade and had a major impact on its economy. Powerful domestic stakeholders in Vietnam and Indonesia, by contrast, were concerned less about international trade and more about maintaining a healthy domestic poultry population. Evidence on vaccination was drawn upon differently depending upon strategic economic positioning either to support or oppose the policy. With influenza A H5N1 endemic in some countries of the region, these policy differences raise questions around regional coherence of policies and the pursuit of an agreed overarching goal, be that eradication or mitigation. Moreover, whilst economic imperatives have been critically important in guiding policy formulation in the agriculture sector, questions arise

    Informal movement of domesticated poultry and wild birds is considered a major threat in terms of highly pathogenic avian influenza (HPAI) H5N1 transmission between birds and from birds to humans. However, the risk of transmission from informal illegal poultry movement has received little attention in Indonesia where human fatalities are the highest in the world. This research investigated the illegal movement of adult poultry between the islands of Java, Bali and Lombok to determine the potential risk of HPAI H5N1 transmission. The aim was to determine known origins and destinations of poultry, estimated quantity and types of birds, people involved and the drivers of illegal movement. Transportation and handling methods and views on how to minimise illegal movement were also investigated. In-depth interviews were carried out with 71 key informants in Bali and Lombok in 2009. East Java was the main origin of poultry entering Bali, followed by Central Java and Lombok. Interviewees estimated that over 10,000 village chickens, 500 ducks and 50 fighting cocks were brought into Bali per month from all origins. However, there were significant discrepancies with quarantine records indicating that the majority of birds imported illegally are not detected. We conclude that although informal illegal movement of poultry in Indonesia poses a potentially high risk for potential HPAI H5N1 transmission if birds are infected, much can be done to increase surveillance, encourage reporting of sick birds, educate traders about the risks and provide effective quarantine within an appropriate cultural framework.

  14. Distribution and burial of organic carbon in sediments from the Indian Ocean upwelling region off Java and Sumatra, Indonesia

    Sediments were sampled and oxygen profiles of the water column were determined in the Indian Ocean off west and south Indonesia in order to obtain information on the production, transformation, and accumulation of organic matter (OM). The stable carbon isotope composition (δ 13C org) in combination with C/N ratios depicts the almost exclusively marine origin of sedimentary organic matter in the entire study area. Maximum concentrations of organic carbon (C org) and nitrogen (N) of 3.0% and 0.31%, respectively, were observed in the northern Mentawai Basin and in the Savu and Lombok basins. Minimum δ 15N values of 3.7‰ were measured in the northern Mentawai Basin, whereas they varied around 5.4‰ at stations outside this region. Minimum bottom water oxygen concentrations of 1.1 mL L -1, corresponding to an oxygen saturation of 16.1%, indicate reduced ventilation of bottom water in the northern Mentawai Basin. This low bottom water oxygen reduces organic matter decomposition, which is demonstrated by the almost unaltered isotopic composition of nitrogen during early diagenesis. Maximum C org accumulation rates (CARs) were measured in the Lombok (10.4 g C m -2 yr -1) and northern Mentawai basins (5.2 g C m -2 yr -1). Upwelling-induced high productivity is responsible for the high CAR off East Java, Lombok, and Savu Basins, while a better OM preservation caused by reduced ventilation contributes to the high CAR observed in the northern Mentawai Basin. The interplay between primary production, remineralisation, and organic carbon burial determines the regional heterogeneity. CAR in the Indian Ocean upwelling region off Indonesia is lower than in the Peru and Chile upwellings, but in the same order of magnitude as in the Arabian Sea, the Benguela, and Gulf of California upwellings, and corresponds to 0.1-7.1% of the global ocean carbon burial. This demonstrates the relevance of the Indian Ocean margin off Indonesia for the global OM burial.

    Recently, Indonesia was ranked as the fourth most populous country in the world. Based on 2012 data, 85000 general practitioners and 25000 specialists are in service around the country. Gastrointestinal (GI) disease remains the most common finding in daily practise, in both outpatient and inpatient settings, and ranks fifth in causing mortality in Indonesia. Management of patients with GI disease involves all health-care levels with the main portion in primary health care. Some are managed by specialists in secondary health care or are referred to tertiary health care. GI endoscopy is one of the main diagnostic and therapeutic modalities in the management of GI disease. Development of GI endoscopy in Indonesia started before World War II and, today, many GI endoscopy procedures are conducted in Indonesia, both diagnostic and therapeutic. Based on August 2013 data, there are 515 GI endoscopists in Indonesia. Most GI endoscopists are competent in carrying out basic endoscopy procedures, whereas only a few carry out advanced endoscopy procedures, including therapeutic endoscopy. Recently, the GI endoscopy training system in Indonesia consists of basic GI endoscopy training of 3-6 months held at 10 GI endoscopy training centers. GI endoscopy training is also eligible as part of a fellowship program of consultant gastroenterologists held at six accredited fellowship centers in Indonesia. Indonesian Society for Digestive Endoscopy in collaboration with GI endoscopy training centers in Indonesia and overseas has been working to increase quality and number of GI endoscopists, covering both basic and advanced GI endoscopy procedures.

    The humanitarian crises caused by the recent droughts (2008-2009 and 2010-2011) in East Africa have illustrated that the ability to make accurate drought forecasts with sufficient lead time is essential. The use of dynamical model precipitation forecasts in combination with drought indices, such as the Standardized Precipitation Index (SPI), can potentially lead to a better description of drought duration, magnitude and spatial extent. This study evaluates the use of the European Centre for Medium-Range Weather Forecasts (ECMWF) products in forecasting droughts in East Africa. ECMWF seasonal precipitation shows significant skill for March-May and October-December rain seasons when evaluated against measurements from the available in situ stations from East Africa. The forecast for October-December rain season has higher skill than for the March-May season. ECMWF forecasts add value to the consensus forecasts produced during the Greater Horn of Africa Climate Outlook Forum (GHACOF), which is the present operational product for precipitation forecast over East Africa. Complementing the original ECMWF precipitation forecasts with SPI provides additional information on the spatial extent and intensity of the drought event.

    In spite of increasing number of cremations in the U.S., little is known about weights of cremated remains. This research was undertaken in order to add to the limited literature on cremains weights and to explore variation. Weights of cremated remains were obtained from the East Tennessee Crematorium. The sample consists of 151 males and 155 females. Age, sex, and race were obtained for each individual. Males are about 1000 g heavier than females. Both sexes lose weight with age, but females lose weight at about twice the rate of males. East Tennessee cremation weights were compared with those from Florida reported by Warren and Maples, and those from Southern California reported by Sonek. East Tennessee results were also compared with an earlier study on ash weight of anatomical human skeletons carried out by Trotter and Hixon. East Tennessee cremations weigh about 500 g more than the samples from Florida and California, and about the same as the earlier anatomical samples. We hypothesize that variation reflects variation in body weight and activity. This variation must be taken into account when cremation weights are at issue.

    2015-01-01

    Recent increases in the volume of labour migration from South-east Asia – and in particular the feminisation of these movements – suggest that millions of children are growing up in transnational families, separated from their migrant parents. Drawing on both quantitative and qualitative data collected in Indonesia, the Philippines, Thailand and Vietnam, the study seeks to elucidate care arrangements for left-behind children and to understand the ways in which children respond to shifts in intimate family relations brought about by (re)configurations of their care. Our findings emphasise that children, through strategies of resistance, resilience and reworking, are conscious social actors and agents of their own development, albeit within constrained situations resulting from their parents’ migration.

    Liang Bua, in Flores, Indonesia, was formed as a subterranean chamber over 600ka. From this time to the present, a series of geomorphic events influenced the structure of the cave and cave deposits, creating a complex stratigraphy. Within these deposits, nine main sedimentary units have been identified. The stratigraphic relationships between these units provide the evidence needed to reconstruct the geomorphic history of the cave. This history was dominated by water action, including slope wash processes, channel formation, pooling of water, and flowstone precipitation, which created waterfalls, cut-and-fill stratigraphy, large pools of water, and extensive flowstone cappings. The reconstructed sequence of events over the last 190k.yr. has been summarized by a series of time slices that demonstrate the nature of the occupational environment in Liang Bua. The earliest artifacts at the site, dated to approximately 190ka, testify to hominin presence in the area, but the reconstructions suggest that occupation of the cave itself may not have been possible until after approximately 100ka. At approximately 95ka, channel erosion of a basal unit, which displays evidence of deposition in a pond environment, created a greater relief on the cave floor, and formed remanent areas of higher ground that later became a focus for hominin occupation from 74-61ka by the west wall and in the center of the cave, and from approximately 18-17ka by the east wall. These zones have been identified according to the sloping nature of the stratigraphy and the distribution of artifacts, and their locations have implications for the archaeological interpretation of the site.
