Abstract

Environmental life cycle assessment on Integrated solid waste management hasdeveloped rapidly during the 1990s and has reached a certain level of harmonisation and standardisation. LCA has mainly been developed for analysing material products, but can also be applied to services, e.g. treatment of a particular amount of solid waste. This paper discusses some methodological issues which come into focus when LCAs are applied to solid waste management systems. The following issues are discussed. (1) Open-loop recycling allocation: besides taking care of a certain amount of solid waste, many treatment processes also provide additional functions, e.g. energy or materials which are recycled into other products. Two important questions which arise are if an allocation between the different functions should be made (and if so how), or if system boundaries should be expanded to include several functions. (2) Multi-input allocation: in waste treatment processes, different materials and products are usually mixed. In many applications there is a need to allocate environmental interventions from the treatment processes to the different input materials. (3) Time: emissions from landfills will continue for a long time.An important issue to resolve is the length of time emissions from the landfill should be considered. Effective schemes need the flexibility to design, adapt and operate systems in ways which best meet current social, economic and environmental conditions. These are likely to change over time and vary by geography. The need for consistency in quality and quantity of recycled materials, compost or energy, the need to support a range of disposaloptions and the benefit of economies of scale, all suggest that integrated waste management should be organized on a large-scale, regional basis. Any scheme incorporating recycling, composting or waste-to-energy technologies must be market-orientated. There must be markets for products and energy.Keywords : municiple solid waste management, economic orientation of waste

Abstract

Clean water to poor communities who live in crowded municipal area is stillexpensive and a luxury. This condition is evidenced by the number of people whouse ground water for their daily water, because water taps still seems expensivefor them. Diarrheal disease is still relatively high for Indonesia, where nearly 16thousand people suffer from diarrhea due to poor sanitation. To help the poor inthe city, there are several alternative technologies that can be applied to publicaccess to clean water and adequate low-cost, including ground water treatmenttechnology with a filter system equipped with an ultraviolet sterilizer, or ozonegenerators, or using ultrafiltration, if possible can also use the reverse osmosismembrane that for fresh water. Arsinum is the best alternative should be chosenfor fulfilled potable water in slump area.Keywords : Sanitation, water treatment technology, portable water, low-cost, slump area

Abstract

The area of Citarum Watershed is cover six regencies: Bandung, Sumedang, Cianjur, Purwakarta, Bogor, and Karawang, West Java. The role and function of upper Citarum Watershed tend to declining, where total of deforestation area reach to a high of 560,095 ha or about 78 % from the total area and part of them already become critical area reach to a high of 143.798 ha. The Debit Ratio of Citarum River or Qmax/Qmin reach to a high of 1,667, it is indicate that Citarum Watershed become very critical condition and need appropriate management especially in the upper watershed. One altervative of the watershed management is application of agricultural forestry system where it is done by integrated development among agriculture, forestry, and animal husbandry. The successful application of agricultural forestry system will lead to conserve land and water where it will support flood control, agricultural irrigation, fisheries development, electric generation, industrial development, etc.Keywords: agricultural forestry, land conservation, watershed

Abstract

As a tropical country, Indonesia has riches of biomass. Cassava is one of biomass which contains plenty of carbohydrate. Carbohydrate then is utilized as a source for producing bioethanol. In producing of bioethanol, the process also yield side product named vinasse. Vinasse is produced from distillation process of solution containing ethanol which has concentration between 7 and 10%. Vinasse contents very high organic substances with COD and BOD concentration amounting of 30,000 mg/L and 27,000 mg/L respectively. Vinasse was then treated in an anaerobic process by using fixed bed digester. Anaerobic fixed bed digester volume was 225 L. The digester was provided with support materialsmade from cutted PVC pipe. The support materials has void volume of 93%. Therefore, the effective volume of the digester was 209 liters. The digester was operated by upflow mode. Research result from this experiment will be utilized as basic design for producing biogas at a bioethanol plant located in Lampung Tengah. Capacity of the plant is 8,000 litres of bioethanol per day. Whereas the vinasse produced is 100,000 litres per day.Keywords: bioethanol, vinasse,fixed bed digester, biogas, casava waste water

Abstract

Waste water produced from Crude Palm Oil’s process in Palm Oil Mill (POM) is usually treated using water treatment ponds that consist of anaerobic ponds and aerobic ponds. It is known well, methane gas is generated from degradation of organic matter in anaerobic ponds. The methane gas results global warming impacts. Regarding to tackle the global warming impact, the methane gas generated from POM can be captured and flared to convert methane gas tocarbon dioxide. This study was conducted in one of the big capacity of Pinang Tinggi POM owned by PT Perkebunan Nusantara 3. Methane gas potential was investigated by using pH, COD (Chemical Oxygen Demand) and waste water measurement. And from these result the methane gas potential was predicted. In this study, using Clean Development Mechanism (CDM), capturing methane gas generated from anaerobic pond gave a result that the project can be an economically feasible based on the condition measured.Keywords : oil palm industry, methane gas, gas rumah kaca, CDM project(CleanDevelopment Mechanism), COD (Chemical Oxygen Demand)
