Renewable Energy Resource for Small Scale Agro-Processing Unit at Turism Area: Case Study at Telaga Warna Purwanto, Y. Aris In the future, Indonesia's energy consumption is expected to increase along with economic growth. To anticipate this energy problem, the Indonesian government plans to increase the number of energy-self-sufficient village. An energy-self-suffiient village is a village capable of meeting its own energy needs and in the process creating job opportunities, reducing poverty and inducing productive activities. Renewable energy, such as solar, wind, micro-hydro and biomass, is usually available in the rural area and hence, by transforming and converting these sources of energy to power various processing machines, added value of agricultural can be made. Utilization of combined solar, wind and biomass for a small scale agro-processing unit at rural area, which uses solar, wind, and biomass as a power source to operate a small agro-processing unit, is one of method to develop rural area. The objective of this study was to explore the potency and the possibility of the use of renewable energy from solar, biomass and wind energy resources for small processing unit at Telaga Warna area, one of the tourism areas located at Bogor, West Java. The results showed that the potency of renewable energy sources at Telaga Warna area was mostly from solar energy and biomass. Potency of renewable energy from solar was 538.6 kWh/m2. Potency of biomass energy from paddy field was 140.1 7 tonlyear and from other area was 2045 m3. The average of wind velocity at Telaga Warna area was lm/s or less than 75 W/m2. The utilization of renewable energy sources at Telaga Warna area was demonstrated for mushroom cracker drying using GHE solar dryer. It was found that for one unit of GHE solar dryer (30 kg of sample) required energy of 25.1 kW. This amound of energy was supplied by solar energy of 4.62kW and the rest was added by biomass energy.

Isolation and identification of bacterial composition of composting process Effendi, Hefni; Widiyanti, Dewa Ayu Devit The research was aimed to identify species and characteristic of bacteria that live in Galuga waste dump site, and to compare hot composting (closed bin) and cold composting (ventilated bin). 7 bacterial genus (Lysteria, Neisseria, Kurthia, Rothia, Acinetobacter, Streptobacillus and Streptococcus) were able to be purified from Galuga waste dump site. Gram positive bacteria are Lysteria, Kurthia, Rothia. and Streptococcus. Gram negative bacteria are Neisseria, Acinetobacter, and Streptobacillus. Among 7 isolated bacteria Lysteria, Neissena, Kurthia, Rothia, Acinetobacter, and Streptobacillus belong to mesophilic bacteria. Meanwhile, Streptococcus is thermophilic bacteria. Composting in closed bin (hot composting) indicated better result than composting in ventilated bin (cold composting). For better composting process, material composting should not only leaves but also other organic materials.

Review on environmental management system of domestic waste management unit in Bogor Prastowo The implementation of an EMS is intended to result in improved environmental performance. In case of Domestic Waste Management Unit (DWMU) in Bogor, the organization could periodically review and evaluate its EMS to identify opportunities for improvement and their implementation. The objective of this study was to review the existing environmental management system operating under Bogor Environmental and Sanitation Agency (DLHK) in compliance with international standard requirements of IS0 14001 Environmental Management System [EMS). The expected result of this research is an evaluation of its EMS to identify opportunities for improvement and their implementation. The management review was conducted based upon the requirements established in IS0 14001 EMS and focusing only on several relevant elements of Domestic Waste Management Unit (DWMU) in Bogor. The EMS elements that were ready to be built in accordance with standard international (EMS IS0 14001), are environmental policy, environmental aspects, legal and other requirements, objectives, targets and programmes, resources, roles, responsibility and authority, competence, training and awareness, operational control, monitoring and measurement. The effectiveness of the EMS could not be evaluated because no document was found showing the trend of environment performance, especially on the significant environmental aspects as well as the achievement of the objective and the target. It is needed to improve the performance of EMS of DWMU that was related to the element of the management: resources, nonconformity, corrective action, preventive action, and management review.

The behavioral study of community to discard trash and management institutions in Bogor City Yulianto, Gatot; Fatchiya, Anna Trash or domestic waste are important to be managed in order not to cause negative impacts. Unfortunately, people's awareness to discard trash is low relatively. It showed that many households discard the trash into rivers and actually the actions are influenced some aspects. This study is important to be done to know some factors that influential to household decisions to discard trash and to know willingness to pay of households to manage the trash in order not to discard the trash into the rivers anymore. The collected data both primary and secundary analyzed by descriptive statistics and inference statistics. Proccesing data is by using a program Minitab 13 For Windows. Result of this study shown that (1) The institution of trash management could be. seen two aspects, namely institutiona on the community level and institution-policy on goverment level. The impacts of behavior change are related to river environmental performance (2) The factors influential to people behavior are household income, the distance between house and river and sufficiency trash facilities. Willingness to pay of households for managing trash in order not to discard trash to the river are lower because of influencial factors, namely amount of running trash payment and household income. Finally, the output of this study will take form as a management analysis that will inform to community, firms and government
