One of the most important of human life is water. Water may provide easily in certain areas , however, some parts in the world are still being suffered from the lack of fresh water. In eastern part of Indonesia for example people found the source of water several kilometers from their home and meet their basic need for their life. This research was executed in Flores Island to identify and explore the underground water which might be trapped under the town of Ende.

Productivity of agricultural land contaminated with tannery wastes originatedchromium is decreased. Crop produced on the contaminated land is toxic for human and animal. An alternative to solve this problem is by using plants which are able to tolerate the contaminant, produce high yield, able to accumulate highconcentration of the contaminant and non consumed. The aim of this research was to find out the effect of cattle manure and biofertilizer in supporting the giant castor bean grown on tannery wastes originated-chromium contaminated land and the ability of cattle manure and biofertilizer in influencing chromium absorptionby the plant.The result showed that giant castor bean can grow normally on chromium contaminated soil. There was no interaction between cow manure and biofertilizer for all observed variables. Cattle manure and biofertilizer have no effect to almost all of the observed variables, except that cattle manure affecting total leaf number and leaf area ratio. Giant castor bean grown on contaminated soils contain 5 – 9 ppm chromium in the leaf. Therefore, giant castor bean could not be considered as higher accumulator plant.

Leachate, especially from the landfill, is a pollutant that can harm human health and pollute the environment including aquatic biota, because the leachate contains various chemicals both organic and inorganic substances and also pathogen bacteria. Laboratory test by Department of Health – Yogyakarta (2001) showed that leachate from landfill had Biological Oxygen Demand (BOD) of 1032 mg/liter in which this was much higher than the limit allowed (BOD = 150 mg/liter. In order to reduce BOD in leachate, a treatment is needed. In this experiment a treatment to reduce BOD in leachate was carried out by applying coagulation andanaerobic bio-filtration with the time of 1, 2, and 3 hours. Evaluation of the tests was conducted using pre-test and post-test with control design which analysis was made descriptive and analytically using T-test with the error of about 5% (á =0,05). Results of the experiment indicated that there was a tendency of BOD reduction of about 0.9% - 1.1% for the control samples, whereas the BOD reduction for leachate attained 82.3% -90.5%. Based on the T-Test, the probability result was 0.000 (p< á =0.05). This means that there is a significant difference in BOD reduction between control samples and leachate. In other words leachate treatment using coagulation – anaerobic bio-filtration can be taken as an alternative process to reduce BOD.

KONSERVASI FLORA, TANAH DAN SUMBERDAYA AIR EMBUNG-EMBUNG DI TIMOR BARAT PROVINSI NUSA TENGGARA TIMUR (STUDI KASUS â€™EMBUNGâ€™ OEMASI-KUPANG DAN â€™EMBUNGâ€™ LEOSAMA-BELU) Wahyu Widiyono

Conservation of flora, soil and water resources are very important to manage‘embung’ ecosystem, in West Timor Island. Generally, ‘embung’ watersheds in this area are degraded, and consequently resulted high runoff and erosion rate; and at the same time, ‘embung’ water has not been used efficiently yet. To conserve ‘embung’ ecosystem, three methods can be applied, i.e.: 1). Flora conservation by using priority of local species; 2). Soil conservation by usingvegetative methods; and 3). Water resources conservation in watershed area by combining flora and soil conservation; and increasing water used efficiency by using intermediate technology.

The research of land productivity through the application of alley cropping has been carried out in transmigration area Kuro Tidur, Bengkulu. The research was done continously within three planting seasons, from 1997 to 1998. The results of the research showed that Flemengia congesta as a fence crop or hedgerows was beneficial. The returning of organic matter from prunning of the hedgerows into the soil can conserve the soil through improvement of nutrients availability, increasing pH, decreasing availability of aluminium (Al) by chelate formation. The effect of dolomit 2,5 ton/ha and organic matter 5,0 ton/ha will increase soy beans production 28,9 % and increase corn production 33,1 %. The effect of dolomit 2,5 ton/ha and organic matter 10,0 ton/ha will increase soy beans production 38,6 % and increase corn production 54,9 %.

Biodiesel has been proven by world wide numerous studies as an environmental friendly alternative diesel fuel. Biodiesel is essentially sulfur free. Engines fueled by biodiesel emit significantly fewer particulates, hydrocarbons and less carbon monoxide than that operating conventional diesel fuel. The maximum utilizationof biodiesel in Indonesia could improve the air quality level in major cities especially in Jakarta. The objective of this study is to assess the effect of biodiesel utilization in transportation sector to the air pollution level in Jakarta. The targeted emission in the study are carbon monoxide (CO), nitrogen oxides (NOx),hydrocarbons (HC), sulfur oxides (SOx) and particulate matter (PM) from vehicle sources. The scenarios used in this study are the utilization of B10 in 2010 and increased to B20 in 2015, B30 in 2020 and B50 in 2025 as an automotive diesel fuel substitution in Jakarta. The result showed that the utilization of biodieselcould improve the air quality level in Jakarta, especially on SO2 and PM emission. By using B10 in 2010, the emission of SO2 and PM will decrease 7,95% (2.070 ton) and 15,62% (1.680 ton) respectively compared to utilizing of pure fossil automotive diesel oil. The highest emission improvement was shown on B50 in2025 scenario. The reduction of SO2 and PM was reached 35,69% (16.660 ton) and 23,21% (4.360 ton) respectively.

Indonesia’s rich supplies of corals and reef fish are endangered by destructive fishing practices. Cyanide and blast fishing are widespread throughout the archipelago even in protected areas. Indonesian reefs are also subject to various pressures from inland activities. Forestation and other land-use changes have increasedsediment discharge onto reefs, and pollution from industrial effluents, sewage, and fertilizer compounds the problem. Cumulatively, these pressures appear to have significantly degraded Indonesia’s reefs over time. Unfortunately, Indonesia has only limited monitoring. Few reefs are regularly studied, making the assessment of condition and change for the country quite difficult. Currently, most monitoringmindicates clearly that reef condition is declining. This article showed the status, biology, and monitoring-rehabilitation method of coral reef in Indonesia.

Buah merah (Pandanus conoideus Lam.) Pandanaceae has several local name in Kelila, Wamena – Papua based on its size, fruit colo, leaf color and taste. It has wide distribution and can be found low land to high land. Buah merah contains valuable nutrients and bioactive compounds in abundant/high concentration, such as: â-caroten, tocopherol, fatty acids (oleic acid, linoleic acid, linolenic acid and decanoic acid). Its cultivation had been done ocal people but not extensively. The easiest way of buah merah propagation was by separating buah merah seedling and stem cutting or byplanting its.The aim of the study were to compile the data that support plant identification of buah merah from Kelila, Wamena-Papua, to study is potency for antioxidant and antidiabetic properties and determine the best media in tissue culture for producing buah merah planlet. The result showed that shoot bud from stem explant cultured in media combination of MS + IBA (2 mg/l) + BA(5 mg/l) produce 10 plantlets, while callus came from leaf tip explant cultured in media combination of MS + BA (5mg/l)+TDZ (0.02 mg/l) The antioxidant test showed that ethyl acetate fraction had good antioxidant activity LC 50 (0.253) while petroleum ether fraction showed good antidiabetic properties with 0.5 % (0.560), 0.25 % (0.593) and control is 0.633.
