Principally, solid waste management is all activities of solid waste handling, from thepoint sources until the final disposal. Up to know solid waste management in urban areais still a complex problem, either from social, management, and technology aspects.The other problem of solid waste management is due to the people behaviour, whichis mostly still unaware. Social capacity is another word social capital means a socialcondition that a lot of citizens participate the process of decision making or policymaking and cooperation with government. The role of community in this system is onlyin paying the monthly fee. So that people still fully gave the solid waste managementsystem in to the government. There is no indication of solid waste sparation by thepeople them selves.

Various organisms, including Lemna sp., have been employed in thetoxicity test of waste, soil, and water. In this experiment Lemna sp. wereexposed to waste water collected from tanneries in Garut, West Java.The experiment system includes liquid medium (macro and micro salts ofMurashige and Skoog), to which a series of concentrations of the pre-filter-sterilized tannery waste water were added aseptically. Aseptic grownLemna sp. were placed on the medium in a density of 10 fronds permedium container. The system was then incubated for 7 days undercontinuous daylight fluorescent lamps and the number of fronds, freshweight and chlorophyll content of the plants were determined. The resultsshow that EC50 of the tannery waste water is 0.66% of waste water. TheLOEC value is 0.1% and the NOEC value could not be determined butshould below 0.1%. This experiment suggests that tannery waste water isdangerous to aquatic plants if it was discharged to public water bodywithout appropriate pre-treatment.

The effort to discover alternative source of energy in the world is still continued because the dependency from the fossil fuel should be aleviated. Since the energy crisis in 1973, the problem of energy become world hudge intention. In every energy crisis, the price of oil increase sharply and cause lack of stock. Therefore, several countries are trying to diversificate their source of energy. One of the alternative energy is biogas. The biogas can be produced from livestock waste. Through the fermentation processing of livestock waste, it can be produced biogas and the other side product and effect from this processing are: organic fertilizer, animals feeding, and prevent pollution. With the several benefits can be taken from the fermentation of livestock waste, the usage of livestock waste become biogas is necessary to be disseminated in Indonesia, where most of people are living in rural area and depending their livelihood on agriculture.

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.

Sistem fitoremediasi berbasis rumput untuk pengelolaan pencemaran lingkungan di tambang minyak telah diteliti. Lima jenis rumput, yaitu Scirpus grossus, Brachiaria humidicola, Eleusine indica, Paspalum notatum, dan Setaria splendida ditanam pada tanah tercemar minyak lama berkadar 3,1%. Pengaruh cekaman salinitas dievaluasi dengan menambahkan air formasi (850 mg/L TDS) ke dalam tanah. Setelah dua belasminggu, parameter pertumbuhan ditetapkan dan kandungan minyak dalam tanah dianalisis. Hasilnya menunjukkan, bahwa semua jenis rumput dapat tumbuh pada tanah tercemar minyak lama. Di bawah cekaman air formasi, jumlah anakan dan berat kering tunas B. humidicola dan S. splendida jelas tertekan, tetapi panjang akar meningkat. Sebaliknya, berat kering tunas pada S. grossus meningkat di bawah cekaman salinitas. Berat kering akar semua jenis rumput secara nyata berkurang dengan cekaman salinitas. Nisbah berat kering tunas terhadap akar relatif tidak dipengaruhi oleh salinitas. Kegiatan degradasi minyak dipengaruhi oleh cekaman salinitas. Kandungan minyak yang hilang dari tanah berkisar antara 32% hingga 50% pada semua jenis rumput.Kata kunci: pencemaran minyak, fitoremediasi, rumput, air formasiÃ‚Â Abstract Experiment to develop a grass based phytoremediation system for environmental management in oil industry has been established in the green house. Five species of grasses, i.e. Scirpus grossus, Brachiaria humidicola, Eleusine indica, Paspalum notatum, dan Setaria splendida, were planted in 6.5 kg oil polluted Semanggi soil (oil content of 3,1%). The effects of salinity were evaluated by adding 800 ml of produced water (850mg/L TDS) to the soil. Growth parameters of the plants and the remaining oil content in the soil were determined in the end of week 12th after planting. The results indicated that all of the grass species are capable of growing well in the polluted soil. However, under the salinity stress, the number of buds on the stolons or rhizomes and the shoot dry weight of B. humidicola and S. splendida are reduced significantly. On the contrary,the root length of the two species is increased; and the shoot dry weight of S. grossus is increased. The root dry weight of all tested species are reduced significantly; however the ratio of shoot dry weight to root dry weight is not influenced by salinity stress. Overall, the oil removal rate from the soil is in the range of 32% to 50%; S. grossus and S. splendida are being the best. The oil degradation activity of the two species is slightly increased under salinity stress condition.Key words: oil polluted soil, phytoremediation, grass, produced water

This article contained several differences of the theory about anaerobicsludge granulation biogas in the UASB reactor. The level of the granulationformation of the beginning followed same principles as the formation bio-film from the bacteria to a surface field. There exist strong facts that thematerial inert played a positive role important and granulation. Mostresearchers took the conclusion that Methanosaeta concilii was the mainkey to the formation of granulation. Only Town Stamp hypotheses thatassumed that the organism autotrophic hydrogenotrophic like for exampleMethanobacterium from strain AZ, could grow in the condition high H2-pressure, was the key to the formation organism of granulation. Severalwriters focus in the stage granulation early and only several contributionsthat discussed the following stage in granulation included maturationgranulation and multiplication. Determining factors granular in the latterstage was dominated in the existence of the manipulation of the pressureelection, through which particle of bigger sludge selectively was kept inthe UASB reactor.

ABSTRACTSeveral alternative waste management innovations from oil palm mills with a capacity of 30 tons / year have been evaluated. These waste innovations are based on the most optimal renewable energy yield produced by oil palm mills, ie biogas, compost and pellets. The evaluation stage begins by collecting data from the operations of the common palm oil factories that is used as the data base-line. Furthermore, preliminary data is compared with the data of waste management innovation which is grouped into 3 (three) activities: (1) compost production from empty bunches, (2) biogas production from liquid waste treatment and (3) pellet production. The comparative results state that the plant's ability to process 1 ton of fresh fruit bunches can produce alternative renewable energy products either 207 kg of compost or 125 kWh of electricity or 125 kg pellets. This paper aims to evaluate the performance of palm oil mills in renewable energy production that is the most optimal in generating the largest profit margin. The results showed that based on the maximum profit potential obtained from each process of waste management, the percentage of the processed waste is about 19.8; 45.5 and 34.6% for the respective compost, biogas and pellet production. The processed waste will earn profit from renewable energy products of compost, biogas and pellet of as many as 6.1; 31.3 and 54.47 US$ / ton respectively. The overall waste treatment requires operating cost of 2.34 US $/ton and will result in a total profit of 91.89 US $ / ton.Keywords: waste, palm oil mill, renewable energy, performance evaluationABSTRAKBeberapa alternatif inovasi pengelolaan limbah dari pabrik kelapa sawit dengan kapasitas 30 ton/tahun telah dievaluasi.

Pulp and paper mills are one of the important industries that contribute ingovernment’s income. Unfortunatelly, they also produce the wastes, such assludge that potentially degrade the environmental quality. The common treatments of sludge are landfilling and incinerating. However, the current trend is to recycle of sludge or it is used for producing the valuable products like absorbents, fillers, compost, etc. These are more attractives than landfilling or incinerating due to economically benefit.
