Indonesia, a nation with more than 230 million population, is the world’s largest archipelagic state located between Asia and Australia continents. In 2000, the production of municipal solid waste (MSW) or refuse in 384 Indonesian cities was about 80,235 tons or 320,940 m3 per day. Refuse generation is predicted to increase five times by 2020. Waste composition is influenced by external factors, such as geographical location, the population’s standard of living, energy source, and weather. Generally, ahigh percentage of organic matter of refuse is between 61 and 72 per cent by weight. The presence of paper, plastic, glass, and metal ranges from 0.4 to 13 per cent. The current handling of refuse in Indonesia is mostly used the disposal land of unhealthy landfill in the form of open dumping. Around 450 units of open dumping have been in operation in Indonesian big cities. These open dumping landfills cause some problems ranging from odor to health problems. Center of Environmental Technology, BPPT has been preparing to carry out landfill mining both for its compost and gas. The gassampling must be done first before it is pumped for energy use. The gas is suggested to be utilized for generating energy, for example for electricity. Initial test indicated that the composition of methane gas (CH4) is around 50%, which is a good enough for energy generation. If the percentage of burnable gas is too low to be used for generating electric energy, it might be mixed with high content of heating value of natural gas (dual fuel system). This paper will present the conditions of open dumping of landfill inIndonesia, and the status and the distribution of its containing gas. From this knowledge of the amount and distribution of landfill gas, it will be analyzed for suggestion how the mined gas will be suitably utilized by the people.

Being located in the equator and also has bondaries with two tectonic plates, Indopnesia has various of energy resources, such as oil, coal, natural gas, as well as, renewable energy resources such as geothermal, solar, hydro, wind etc. In relation to the above mentioned conditions, Indonesia has a lot of potential to reduce greenhouse gas emmission through increasing the energy efficiency, fuel swiching, as well as utilization of CCS (carbon dioxide capture and storage) in the oil, gas and coal mining. Although Indonesia is not included in Kyoto Protocol’s country list, Annex I or Annex II, Indonesia is inclkuded among countries that had ratified the Earth Summit and the Kyoto Protocol. Therefore, it has a responsibility to help the developed country reduce their greenhouse gas emmission through application of environmental friendly technologies in the framework of Clean Development Mechanism.

In the last ten years water pollution problem in Jakarta has been becoming more serious. The highly increasing population causes the rising amount of domestic wastewater. Rivers in Jakarta have already been polluted by various wastewaters, such as from industries, domestic and many institutionals (offices, hospitals, markets/shop areas, etc.). It has been well known that the domestic wastewater contributes 70% in causing the river pollution, especially in Jakarta. Therefore it is very important to apply the proper domestic wastewater treatment system which is able to reduce thecontaminants until an environmentally required standard. Some types of domestic wastewater treatment have already been used, but the results do not fulfil the environmental required standard. At least a unit of domestic wastewater treatment should have a control tank as the beginning filter, anaerobic part, aerobic part and a sedimentation tank as the final part of the whole system. An advanced technology using a biofilter media has been proposed and based on the experiment, the result has proven that it can reduce BOD from more than 1,000 ppm to less than 30 ppm. The retention time is about 3 days. The conclusion shows that this new wastewatertreatment system is properly suitable alternative to be applied in domestic area, especially in a densely populated region. By applying the system we can also cope with the water pollution problem caused by domestic wastewater.

The organic concentration of soft drink factory waste water has not high organic concentration, therefore one of the alternatives of the treatment technology is using aerobic system : activated sludge. On this observation can be seen that the system can be used as waste water treatment for soft drink that is not so high in COD contain and the criteria parameters design can be fulfilled by process parameters during operation the system. The parameters that are not fulfill the design parameters is caused by the shock loading of toxic material or by the high loading rate of substrate of waste water. Based on parameter criteria as mention above, the efficiency that can be reached of this process is about 61,22%.

Ground water potential map showed that the Salimpaung in Tanah Datar District has very low water resources potential. Deep and shallow water resources were found in some places and in a limited area.Interpretation of imaging resistivity showed that water resources potential lies in P1 and P2 layers. This layers were found in 90 to 150 meters to the south of the mosque. The potential layer was found between 10 to 30 meter depth and thickness between 5 to 25 meter and lies in observation point between 50 – 125 meter. Water resources at layer P1, P2, P3 and P4 has medium to low potential and the water layers was interpreted as water trap above the rock layer. The other water resources potential were found at P5, P6 and P7, at 90 – 150 meter to the north of the mosque. The potensial aquifer lies beneath hard rock at depth 40 to 60 meter.

Leather industries contribute significant problems due to the hazard wastes, that threat to environmental sustainability and to human health. The negative impacts are particularly caused by the chemical compounds used in the conventional process of the leather tannery, such as lime, sodium sulphide, chrome, etc. Enzyme is protein compound from biological system, that acts as catalyst (bio-catalyst). Enzyme can be used to replace partly or complete the chemicals used in tannery processes. Recently, micro-organisms are considered a appropriate device to produce enzymes. Furthermore, it is necessary to select potential micro-organisms for enzyme production.“Exolite”, that is first enzyme produced in pilot scale in Indonesia, proved to reduce significantly pollutant in waste of leather tannery industries. Therefore, the development of enzyme industry in Indonesia is needed to be supported.
