  8. Proxy Records of the Indonesian Low and the El Ni{tilde n}o-Southern Oscillation (ENSO) from Stable Isotope Measurements of Indonesian Reef Corals

    The Earth`s largest atmospheric convective center is the Indonesian Low. It generates the Australasian monsoon, drives the zonal tropospheric Walker Circulation, and is implicated in the genesis of the El Nino-Southern Oscillation (ENSO). The long-term variability of the Indonesian Low is poorly characterized, yet such information is crucial for evaluating whether changes in the strength and frequency of ENSO events are a possible manifestation of global warming. Stable oxygen isotope ratios ({delta}{sup 18}O) in shallow-water reef coral skeletons track topical convective activity over hundreds of years because the input of isotopically-depleted rainwater dilutes seawater {delta}{sup 18}O. Corals also impose a temperature-dependent fractionation on {delta}{sup 18}O, but where annual rainfall is high and sea surface temperature (SST) variability is low the freshwater flux effect dominates.

    In Indonesia, herbal medicines are usually produced by small and medium enterprises which are relatively low in quality control. The purpose of this paper is to report that we have developed a taste sensor system with global selectivity, i.e., electronic tongue (e-tongue) for differentiation of Indonesian herbal medicines. The e-tongue was composed of five kinds of ion selective electrodes as working electrodes, data acquisition system, and pattern recognition system. Each ion selective electrode (ISE) was built by attaching lipid/polymer membrane. For this purpose, the five kinds of membranes were built by mixing lipid, plasticizer (nitrophenyl octyl ether/NPOE), polyvinyl chloride (PVC), and tetrahydrofuran (THF). In this study, we employed five kinds of lipid, namely oleic acid (OA), dioctyl phosphate (DOP), decyl alcohol (DA), dodecylamine (DDC), and trioctyl methyl ammonium chloride (TOMA). In this case, the membranes transform information of taste substances into electric signal. The five kinds of Indonesian herbal medicine were purchased from local supermarket in Yogyakarta, i.e., kunyit asam (made from turmeric and tamarind), beras kencur (made from rice and kencur), jahe wangi (made from ginger and fragrance), sirih wangi (made from betel leaf), and temulawak (made from Javanese ginger). Prior to detecting the taste from the Indonesian herbal medicine samples, each ion selective electrode was tested with five basic taste samples, i.e., for saltiness, sweetness, umami, bitterness, and sourness. All ISEs showed global selectivity to all samples. Furthermore, the array of ISEs showed specific response pattern to each Indonesian herbal medicine. For pattern recognition system, we employed principle component analysis (PCA). As a result, the e-tongue was able to differentiate five kinds of Indonesian herbal medicines, proven by the total variance of first and second principle components is about 93%. For the future, the e-tongue may be developed for quality control application in herbal medicine industries.

    A graph shows how Indonesia's prices for regular and premium leaded gasolines and diesel fuel compare to the world average price, in US dollars per gallon: USA $0.28 lower for regular leaded gasoline, $0.30 lower for premium leaded, and $0.48 lower for diesel. Such proximity to world averages is of note in the context that Indonesia, a developing country with pressing needs for industrial and social development, does not internally provide the deep consumer subsidies that have long persisted in many such oil-producing countries. Although the other three countries shown on the graph have recently moved to cut internal fuel price subsidies, they still price these three important fuels more deeply below the world average than does Indonesia. A table details Indonesia's internal market price changes over time, by petroleum product. A chart tracks Indonesia's oil exports since 1966. The year of the first world oil price shock, 1973, shows a dramatic increase in exports, but that near-doubling was not repeated during the period of the second price shock, 1978-1979. As of 182, exports (by now including condensates) had fallen to pre-Arab Oil Embargo levels. This issue contains the fuel price/tax series and the principal industrial fuel prices for August 1984 for countries of the Western Hemisphere. Also, beginning with this issue, Energy Detente will appear only in English rather than both English and Spanish, as heretofore.

    Over the last 20 years, the government of Indonesia has undertaken an extensive program to provide electricity to the population of that country. The electrification of rural areas has been partially achieved through the use of isolated diesel systems, which account for about 20% of the country`s generated electricity. Due to many factors related to inefficient power production with diesels, the National Renewable Energy Laboratory, in conjunction with PLN, the Indonesian national utility, Community Power Corporation, and Idaho Power Company, analyzed options for retrofitting existing diesel power systems. This study considered the use of different combinations of advanced diesel control, the addition of wind generators, photovoltaics and batteries to reduce the systems of overall cost and fuel consumption. This analysis resulted in a general methodology for retrofitting diesel power systems. This paper discusses five different retrofitting options to improve the performance of diesel power systems. The systems considered in the Indonesian analysis are cited as examples for the options discussed.

Two international independent power consortia are developing two units each, while PT Perusahaan Listrik Negara (PLN), the Indonesian state utility, owns and operates two others. Two final units have yet to be awarded.

    An Indonesian, Colombian, and Russian coal were tested in the Energy & Environmental Research Center's combustion test facility for their performance and an evaluation of mercury release and capture with selected additives in both electrostatic precipitator and baghouse configurations. Sorbents included the carbon-based materials NORIT DARCO Hg, Sorbent Technologies B-PAC and B-PAC LC, STI Rejects provided by Constellation Energy, and Envergex e-Sorb, along with ChemMod's high-temperature additive. Each coal was evaluated over several days and compared. Ash-fouling tests were conducted, and mercury levels were monitored using continuous mercury monitors (CMMs). The Ontario Hydro mercury sampling method was also utilized. The Indonesian coal had the lowest ash content, lowest sulfur content, and lowest energy content of the three coals tested. The Colombian coal had the highest mercury content and did contain a significant level of selenium which can interfere with the ability of a CMM to monitor mercury in the gas stream. All sorbents displayed very favorable results. In most cases, mercury removal greater than 86% could be obtained. The Indonesian coal displayed the best mercury removal with sorbent addition. A maximum removal of 97% was measured with this coal using Envergex's carbon-based sorbent at a rate of 4 lb/Macf across an electrostatic precipitator. The high ash and selenium content of the Colombian coal caused it to be a problematic fuel, and ash plugging of the test furnace was a real concern. Problems with the baghouse module led to limited testing. Results indicated that native capture across the baghouse for each coal type was significant enough not to warrant sorbent addition necessary. The fouling potential was the lowest for the Indonesian coal. Low sulfur content contributes to the poor potential for fouling, as witnessed by the lack of deposits during testing. The Russian and Colombian coals had a much higher potential for fouling primarily because of their high ash contents, but the potential was highest for the Colombian coal. Of the three coals tested, the Colombian would be the least desirable.

    Xie, X.F.; Ohki, A.; Maeda, S.

    1999-07-01

    Australian low-rank coals, Loy Yang coal, Yallourn coal and Indonesian Adaro coal are hydrothermally treated at 200-350 C. The simultaneous TG/DTA is used to investigate the thermal properties, which include the volatile release profile under a nitrogen atmosphere and the burning profile under an air atmosphere. It is found that the temperature of volatile matter combustion (Ti1) of the hot water dried coals (upgraded coals) increases with heat treatment temperature (HTT), whereas the temperature of char combustion (Ti2), the temperature of maximum reaction (Tmax) and the temperature of char burn out (Tout) do not have large increase on the HTT. These results suggest that the HWD process can raise the volatile matter ignition temperature, resulting in improving the spontaneous ignition temperature, but it still maintains the original combustion behavior. Results from TG-DTA measurements are consistent with those determined by FTIR and solid state {sup 13}C CP/MAS NMR.

    Tsunami is a series of wave trains which travels with high speed on the sea surface. This traveling wave is caused by the displacement of a large volume of water after the occurrence of an underwater earthquake or volcano eruptions. The speed of tsunami decreases when it reaches the sea shore along with the increase of its amplitudes. Two large tsunamis had occurred in the last decades in Indonesia with huge casualties and large damages. Indonesian Tsunami Early Warning System has been installed along the west coast of Sumatra. This early warning system will give about 10-15 minutes to evacuate people from high risk regions to the safe areas. Here in this paper, a mathematical model for Tsunami evacuation is presented with the city of Padang as a study case. In the model, the safe areas are chosen from the existing and selected high rise buildings, low risk region with relatively high altitude and (proposed to be built) a flyover ring road. Each gathering points are located in the radius of approximately 1 km from the ring road. The model is formulated as an optimization problem with the total normalized evacuation time as the objective function. The constraints consist of maximum allowable evacuation time in each route, maximum capacity of each safe area, and the number of people to be evacuated. The optimization problem is solved numerically using linear programming method with Matlab. Numerical results are shown for various evacuation scenarios for the city of Padang.

    A mega-tramway based on the Indonesian islands of Sumatra and Java is proposed to span Sunda Strait. The Java-Sumatra Aerial Mega-Tramway (JSAMT) will be self-elevating and will regularly and cheaply launch passengers and cargoes via two conveyor belt-like facilities using standard winged shipping containers like those currently used by international trucking and ocean shipping industries that are volplaned across the Sunda Strait. The JSAMT will be a self-sustaining toll facility free of any requirement for international loans or funding guarantees for its construction. Its existence will remove any immediate need for an expensive to dig/maintain Nusantara Tunnel. We offer the formative basic technical specifications for the JSAMT and indicate some of the physical and cultural geographical facts underpinning our macro-engineering proposal; offshoots of a perfected and tested JSAMT may be installed at Palk Strait between India and Sri Lanka, the Gibraltar Strait and the Bering Strait by mid-21st Century.

    The advantages of interconnecting large electric power systems has been almost universally accepted in those parts of North America that are not geographically isolated. However, interconnecting power systems can result in significant economic advantages, even in those parts of the world where power systems are small and widely separated. This paper examines two small, isolated power systems on the island of Borneo in Southeast Asia. The Malaysian State of Srawak lies on the north coast of Borneo. With an area of 123,156 square km (47,555 square mi.) and population of 1.7 million, it is the largest, but most sparsely populated, state in the Federation of Malaysia. Its neighbor to the south is the Indonesian Province of West Kalimantan. A study examining the feasibility of interconnecting these two power systems was undertaken in 1994 as a part of the Association of Southeast Asian Nations (ASEAN) initiative to interconnect the power systems in the region. The ASEAN region is characterized by rapidly growing economies and rapid load growth.

    This paper describes three wind energy related projects which are underway in Indonesia. The first is a USAID/Winrock Wind for Island and Nongovernmental Development (WIND) project. The objectives of this project are to train local nongovernmental organizations (NGOs) in the siting, installation, operation, and maintenance of small wind turbines. Then to install up to 20 wind systems to provide electric power for productive end uses while creating micro-enterprises which will generate enough revenue to sustain the wind energy systems. The second project is a joint Community Power Corporation/PLN (Indonesian National Electric Utility) case study of hybrid power systems in village settings. The objective is to evaluate the economic viability of various hybrid power options for several different situations involving wind/photovoltaics/batteries/diesel. The third project is a World Bank/PLN preliminary market assessment for wind/diesel hybrid systems. The objective is to estimate the size of the total potential market for wind/diesel hybrid power systems in Indonesia. The study will examine both wind retrofits to existing diesel mini-grids and new wind-diesel plants in currently unelectrified villages.

    All of the major international oil companies have extensive operations in the Far East, and in most cases, these operations account for a significant part of their worldwide earnings. In the refining and marketing end of the business, near-term profitability could be hampered by problems in the Singapore refining center. An expansion of Indonesian refining capacity has reduced profits from processing arrangements, and new Saudi product exports will enter Singapore starting this year. Longer term, however, the strong economic growth in the region renders it a highly attractive area in which to operate. On the producing end, rising output will boost profits for the international oil companies in Indonesia and Malaysia. Caltex (a 50/50 joint venture between Chevron and Texaco) is one of the largest marketers in the Far East. It will not initially be affected greatly by the Singapore refinery problem, as its production from this area goes directly into its own marketing system rather than into the open market. Exxon is a medium-size marketer with especially strong positions in Japan, Malaysia and Thailand. However, the company could be vulnerable to near-term problems in Singapore. Mobil, another medium-size marketer, has a very strong position in Japan but problems in Australia. As those problems are corrected, earnings should grow over time. The Royal Dutch Shell Group is one of the largest marketers in the Far East, with good positions in Singapore, Malaysia and Australia. Shell will have difficulty adjusting to the changing conditions in Singapore, but once this is complete, downstream earnings growth should resume. British Petroleum (BP) has a smaller upstream and downstream presence than the other international oils. Estimated 1983 Far East earnings are tabulated for these five companies. 5 figures.

    Sesbania sesban, locally named as Jayanti, is one of Indonesia plants belonging to Fabaceae family. This species is traditionally used by Indonesian people to cure digestive disorders, fever, or headache. Jayanti can grow well in tropical to subtropical region, such as in Asia and Africa. Based on literature, qualitative analysis of the methanol extract of leaves of S. sesban showed that it contained flavonoids, alkaloids, saponins and glycosides. In addition, the activity assay of extracts of different tissues of this species showed antitumor, antimalarial, and antidiabetic activityies (leaves and seed extracts), antioxidants (flower extract), and analgesic (wood extract). Though the extracts of S. sesban parts showed interesting activities, chemical study of those extracts have not been widely reported. Therefore, the objective of this research was to isolate the secondary metabolites from methanol extract of leaves of S. sesban and to determine their cytotoxicity against murine leukemia P-388 cells. One compound has been obtained and identified as 3-hydroxy-4',7-dimethoxyflavone (1), a new isolated compound from nature. This compound was obtained through separation of methanol extract using various chromatographic techniques, such as vacuum liquid chromatography and radial chromatography. The structure elucidation of isolated compound was based on 1D NMR ({sup 1}H-NMR and {sup 13}C-NMR) and 2D NMR (HMBC). The cytotoxicity of methanol extract and compound 1 against murine leukemia P-388 cells examined through MTT assay showed IC{sub 50} value of 60.04 ?g/mL and 5.40 ?g/mL, respectively.

    Many have come to realise that an increasing demand for and supply of energy is a necessity to support national development. Conservation efforts also contribute, by the more efficient use of energy and by avoiding its unnecessary use. However, some are of the opinion that conservation would be able to add to the supply of energy, but this viewpoint still requires further consideration. In Indonesia, the energy consumption since 1970 has been continually increasing with an average rate of 10.6%/year in support of the development in all sectors. In the case of electric energy for the whole of Indonesia, in the year 1990/1991 the installed capacity was 9275 MW in the State Electricity Company (PLN) network with an electrical consumption during that year amounting to 34.0 TWh. The increase of consumption during the last two years amounted to 17.5% and 17.9%/year. Over this period the share of supply of electricity has consistently increased. Specifically for the island of Java, which accounts for 80% of all of the Indonesian electricity consumptions, the installed capacity by PLN in the year 1990/1991 was 6363 MW (the same amount of capacity also exists outside PLN), and increased by 17%/year during it last three years. The actual and projected figures at Oven. It is worth noting that, for example, the projected installed capacity for 2003-04 is now 31.8 GW, which is far higher than the previous projection for 2010-11 of only 25.5 GW. In view of this the government has decided to conduct feasibility studies of the nuclear option, with the goal of fulfilling the deficit or gap in supply where other options are likely to reach their limitations.

    We have explored surface water mixing in the Lombok Strait through a {approx}bimonthly resolved surface water {Delta}{sup 14}C time-series reconstructed from a coral in the Lombok Strait that spans 1937 through 1990. The prebomb surface water {Delta}{sup 14}C average is -60.5{per_thousand} and individual samples range from -72{per_thousand} to 134{per_thousand}. The annual average post-bomb maximum occurs in 1973 and is 122{per_thousand}. The timing of the post-bomb maximum is consistent with a primary subtropical source for the surface waters in the Indonesian Seas. During the post-bomb period the coral records regular seasonal cycles of 5-20{per_thousand}. Seasonal high {Delta}{sup 14}C occur during March-May (warm, low salinity), and low {Delta}{sup 14}C occur in September (cool, higher salinity). The {Delta}{sup 14}C seasonality is coherent and in phase with the seasonal {Delta}{sup 14}C cycle observed in Makassar Strait. We estimate the influence of high {Delta}{sup 14}C Makassar Strait (North Pacific) water flowing through the Lombok Strait using a two endmember mixing model and the seasonal extremes observed at the two sites. The percentage of Makassar Strait water varies between 16 and 70%, and between 1955 and 1990 it averages 40%. During La Nina events there is a higher percentage of Makassar Strait (high {Delta}{sup 14}C) water in the Lombok Strait.

    Indonesia has Indonesian Tsunami Early Warning System (Ina-TEWS) since 2008. The Ina-TEWS has used automatic processing on hypocenter; Mwp, Mw (mB) and Mj. If earthquake occurred in Ocean, depth < 70 km and magnitude > 7, then Ina-TEWS announce early warning that the earthquake can generate tsunami. However, the announcement of the Ina-TEWS is still not accuracy. Purposes of this research are to estimate earthquake rupture duration of large Indonesia earthquakes that occurred in Indian Ocean, Java, Timor sea, Banda sea, Arafura sea and Pasific ocean. We analyzed at least 330 vertical seismogram recorded by IRIS-DMC network using a direct procedure for rapid assessment of earthquake tsunami potential using simple measures on P-wave vertical seismograms on the velocity records, and the likelihood that the high-frequency, apparent rupture duration, T{sub dur}. T{sub dur} can be related to the critical parameters rupture length (L), depth (z), and shear modulus ({mu}) while T{sub dur} may be related to wide (W), slip (D), z or {mu}. Our analysis shows that the rupture duration has a stronger influence to generate tsunami than Mw and depth. The rupture duration gives more information on tsunami impact, Mo/{mu}, depth and size than Mw and other currently used discriminants. We show more information which known from the rupture durations. The longer rupture duration, the shallower source of the earthquake. For rupture duration greater than 50 s, the depth less than 50 km, Mw greater than 7, the longer rupture length, because T{sub dur} is proportional L and greater Mo/{mu}. Because Mo/{mu} is proportional L. So, with rupture duration information can be known information of the four parameters. We also suggest that tsunami potential is not directly related to the faulting type of source and for events that have rupture duration greater than 50 s, the earthquakes generated tsunami. With available real-time seismogram data, rapid calculation, rupture duration discriminant can be completed within 4-5 min after an earthquake occurs and thus can aid in effective, accuracy and reliable tsunami early warning for Indonesia region.
