As a result of population pressure, deforestation in Java has increasedconsiderably that causes an increase on critical land. The situation is worsened by increasing of kerosene and diesel prices that causes to an increase on fuelwood utilization that would lead to increase of illegal cutting. The increase of critical land could lead to increase of soil erosion, landslide, and flood as a result of a reduction in water absorption and soil retention. The Department of Forestry has initiated a reforestation program to ameliorate the situation. However, as the limited budget, the economics of the program needs to be examined further. Based on benefit-cost ratios, economic contributions of the fuelwood component indicated that the reforestation program or energy plantation was economically unfeasible. However, by including benefits of soil erosion control the program waseconomically attractive on some sites. A methodology was developed to prioritize which critical land to reforest. This was applied by identifying market price of fuelwood at minimum yield that would justify an energy plantation investment. The method indicated that subject to budget availability, critical lands should be reforested in descending order of productive potential until the site of minimum yields is reached.

The application of high technology (hitech) for solid waste management andtreatment in Singapore is one of examples of solving the municipal solid waste problem. Singapore with more than 4 million inhabitants produced 7676 ton wastes per day in 2001. Now, all the combustible solid wastes goes to the incinerator plant that can convert the heat into electricity. The ash from incinerator and the incombustible solid wastes are transported via waste harbour in Tuas to the Semakau off shore landfill. Also, before incinerating in the plant, the activities of collecting and transporting of munocipal solid wastes are suported by such kind of new technologies for example pneumatic refuse transport system. The typical of the high tecnology is need high cost for building, operating and maintaining and should be operated by high skill staff. Singapore has all the need and also has a strong political will in combating the solid waste problems. So that, Singapore is one of the cleanest metropolitan cities in the world.

Recycling used battery to collect lead (Plumbum) have been executed by communities. This practice has been accepted for generations, and they have not accomplished scientific assessments yet, particularly in term of environmental aspect. In order to create synergy between potential economic and prevent environmental impact of this performance, therefore it is absolutely necessary to manage lead recycling from battery activities. Using appropriate technology could also reduce air pollution of lead dust (Pb particulate) andexcess air.

Analysis methods by using passive sampler for the content of pollutant materials in the ambient air, such as the content of NO2, SO2, O3, etc, has been widely used and applied in several countries. The advantage of this method is easier to carry and more moveable, and taking samples among various locations with different weather, compares to others. In Indonesia this method is not much known yet.The writers through a collaboration of research with The University of Tokushima-Japan, is trying to apply one of passive sampler method in order to measure the concentration of NO2 in the air on several locations in Jakarta, Surabaya and Bandung. Hence, The result of analyze in Indonesian was comparing with the result in the others country by used thesame methods. The conclusion of this research is the quality of the air on Indonesian city worse than the Asia city, so in the future Indonesian government can give more attention to handle the air pollutant.

The catchment area “Citarum” has been being in a very critical condition relating to extremely environmental problems. River water pollution in this catchment is obviously caused by industrial and domestic waste water. Nowadays the pollution load is already too high and the BOD, COD contents exceed the WHO standard. The activity evaluating groundwater environment in the up steam of the catchment area has the objective wich is to monitor the effect of groundwater pollution brought about by decreasing of surface water quality in upstream Citarum. The observed locations are village Suleman, Mekarrahayu, Margarahayu and Nanjung. They are all in Bandung regency. The four observed locations can be as representative for the three parts of upstream Citarum, ie. Upper, middle and lower part. Results of the evaluation are able to described groundwater quality condition, especially in the upstream Citarum cathment area.

Along with the increase of population and industries in Indonesia especially in DKI Jakarta, the river’s water quality for raw water supply for drinking water treatment is decreasing. And society’s growing concern towards sanitation prompted an increase in the usage of detergents as a cleaning item. In effect, waste excerted by these items contributes to that decrease.This decrease in river’s water quality has increase the expense needed to process drinking water out of it. At this time, PAM (Drinking Water Enterprise) use Active Carbon Powder to remove the detergents from raw water by the adsorption method. The Active Carbon Powder is the main reason behind the increase expense as the powder is quite expensive.To counter the problem, an alternative method is a biological process such as an Aeration Contact using a charcoal as a medium. The process utilizes microbe activities within the river’s water itself. Previous experiments resulted in this : A process with a hydraulic retention time of six hours result in a 90,95 % efficiency rate of detergents removal and a 72,22 % efficiency rate of other organic substance removal.

As the capital city of West Kutai Regency, Sendawar still has a lot of problems relating to clean water supply for its residence. Those problems are caused by the very limited capability of local water authority (PDAM), the worse of environment management and water pollutions. Water pollutions occur because of improper mining activities (gold, silver and coal), domestic wastewater and sediment particles affected by increasing run off coefficient and erosion. Therefore the quality of surface water (River Mahakam) becomes worse and worse. PDAM Problems are not only being able to serve clean water need just for 19% residence in Sendawar, but also the low capability of human resources. There are three ways to solve those problems. Firstly, it is very important to apply a concept “One River One Management” in the Mahakam Catchment Area. Secondly, Application ofwastewater treatment technology must be carried out to reduce the pollutants produced from mining industries and municipal area. The third is by improving the human resource quality, especially in the field of environment and sustainable development.
