The treatment of wastewater containing high concentration of nitrate and lowconcentration of BOD using autotrophic bacteria were conducted in batchsuspension experiment to investigate nitrate concentration level which can betreated by the bacteria. The autotrophic bacteria were enriched by acclimatingactivated sludge with inorganic substrates. The experimental result shows thatdenitrification reaction with initial nitrate concentration in synthetic wastewater from 200 to 850 mg/l proceeded according to the one-order reaction. The denitrification rate increased with increasing the initial nitrate concentration. Sulfate was detected as the by product of the denitrification reaction. The sulfate produced for 1 mmol of nitrate decreased was 1.09 mmol.

Some observation result said that the worst of enviromental uality happened is primarily caused by mislead in the aim of develoment nature resources that only concern to economic growth. Therefore, the develoment of brakisth water ecosystem as an economic growth region should be relatedto the goal of enviromental waters uality management. To enhance this goal, the people utilizing brakish water ecosystem as aquaculture site may reduce organic pollution that is producedby their activities. Integrationof Gracilaria sp as a biofilter agent in aquaculture pond or in the wastewater treatment system is an alterantivetechnology for waters quality recovery enhancement.The initial success of this method in some countries has been reported. Therefore, if the biofiltration process in reducing organic pollution run properly, waters pollution in certain brakish ecosystemmaybe reduced.

In attempt to know the trophic status and phytoplankton community in Juandareservoir this research was conducted. This research revealed that based onsecchi disk and concentration of Chlorophyll-a the Juanda reservoir have become eutrophic, with phytoplankton density was about 27,779-43,439 x 10-3 cell/l. The phytoplankton community was dominated by Synedra sp. (22.4-33.8%) and Microcystis sp. (10.2 –31.4 %;). However this result was about 1000 x bigger than previous publication which reported the phytoplankton density in Juanda reservoir was only about 621- 35,514 cell/l, and the phytoplankton community was dominated by Microcystis sp. which always > 85%. These differences were suggested due to using net-plankton in the sampling of phytoplankton.

BPPT has conducted Integrated Research on Biogas from night soil. This research has done thought pilot plant in Pondok Pesantren Tebu Ireng Jombang East Java. The product of the biogas pilot plant are compost and methane gas. The using of these products has been researched to the community. The community survey using descriptive methods, has a result that 79.5 % of the respondens said they intend to use composts for their plantation.There fore the application of biogas technology in waste water treatment should be socialized.

Integrated watershed management, which aims at restoration of a soundhydrologic regime in the watershed considering water resources utilization,appropriate landuse, water quality control and environmental conservation, is becoming crucially important in Indonesia. Because, the land degradation of watershed in Indonesia more increases every time. There is a growing concern that many parts of the Indonesia watershed will continue to face problems of watershed degradation. The basic problem in most watershed area, especially in Java, is too many people being concentrated on too small land base. Besides that, the causes of watershed degradation are complex and interrelated, such as too much emphasis being placed on economic growth in the management of natural resources, and the continuing presence of poverty, population growth, infrastructural and industrial development. Thus, the exisiting environmental problems and their overall impacts are not only biophysical in nature, but also social.The integrated watershed approach stresses the interaction of all activities that take place throughout the watershed. The strategy of watershed management approach uses new paradigm with people of participation and using community development in operational, practices and bottom up approach.

To fulfill the people’s primary need, the government is duty bound to stock remote regions with a steady supply of fresh water. That duty necessitates assasing and applying of appropriate water treatment system in these remote regions or villages. In fact the number of people needing the service is few, and the education level of the people is generally low. Having a small scale and simple water treatment technology would fit this standard. There are many water treatment technology, but only a few should be applied for a minimal capacity production. The applied technology should benefit the localpeople and, in accordance with local’s conditions, long-lasting. This paper will discuss various water treatment technology suitable for a small-scale production. The technologies are selected based on its ability to purify thewater and the cost of each system. The calculations were derived from otherwritten sources along with field data gathered by BPPT. These technology include the coagulation-filtration technology, slow-sand filtration technology, ion-exchange technology, reverse-osmosis technology and the active-carbon technology.

Aquatic plants (Eichornia crassipes, Pistia stratiotes and Salvinia cucullata)were grown in a nutrient solution in the presence of Cd ion (0,2 mg/L). Analysiswere performed to established whether there was a removal of Cd in solutionand there was accumulation of Cd in the roots and shoots of the plants.Analysis of Cd concentrations in water was performed everyday and at the endof the experiment the shoot and root of the plants was harvested. The resultsshowed that Cd concentrations in all solutions declined until tenth day.Eichornia crassipes could remove Cd in solution completely by six days. WhilePistia stratiotes and Salvinia cucullata of Cd removal rate were 93,5 % and 77,4%, respectively. Root to shoot concentration ratio of Cd was 36 for Eichorniacrassipes and 10 for Pistia stratiotes.

The degradation rate of forest in the recent 5 years increases rapidly,particulartly in Sulawesi. The biggest damaged comes from the human impact,which spreads to the conservation area. As a result, the areais decreased,whereas its function and its potency have not been explored. The ecologicalresearch has been conducted in Soloi forest, Suaka Margasatwa Buton Utara inMay 2003. The objectives of this work are to study the condition, which belongto. 75 general and 35 families with density of trees are 277 individual (stemdiameter > 10 cm ), and 1140 sampling ( 2-9,9 cm stem diameter ). The foresttype is low land primary forest, which dominated by Casearia rugulosa,Diospyros pilosanthere, Cleistanthus myriantus, Canarium hirsutum, andDrypetes longifolia. In the forest structure, trees with 10-20 cm stem diameter isin the first rankwith the total number 57,02%, then followed by the trees with 20-30 cm diameter (20,22%). In general, the forest condition in research site isgood, although a few areas are damaged due to illegal loging.

Anaerobic fixed bed reactor is a fermentation anaerobic reactor used microorganism attached growth system, where degradation of organic material done by microorganism that growth in support material as fixed film. This system mostly used for organic wastewater treatment now. The assessment is carried out for the Slaughterhouse wastewater treatmentwhere the support material for microorganism growth is a fabricated media. Plant is a demonstration scale by digester volume of 600 m . Wastewater is feeding to the digester by up flow system. The wastewater pumped from the bottom of the digester, flow through the support material, contact with the microorganism fixed on the media. Degradation of the organic waste process is take place along wastewater contact with the fixed film.Observation is on the performance of the reactor by the influence of organic loading to the pollution degradation of slaughterhouse wastewater called reactor efficiency. Fixed Bed Reactor performance still reached until 3 days hydraulic retention on organic loading rate about 3.05 kg COD/m hr, and efficiency 75 %.
