- Analysis of Leachate Recycling Rate toward Biogas Quality with Green Phoskko (GP7) and Partitioned Reactor Muhammad Adi Nugraha, 2014, 45 Page, 14 Table, 19 Picture, 3 Appendix Energy is one of essential elements in life community because all of human activities always depend on energy. Most of the energy used by people nowadays come from fossil energy such as petroleum. Some researches have been done in order to discover alternative energy resources. One of them is biogas. Biogas is a term that is used to refer to a type of gass that can be renewed and produced from anaerobic digestion or fermentation of organic matter with the help from metanogenesis bacteria. One factor that can influence the production of biogas in fermentation process was concentration level of organic feed or leachate recycling. The function of leachate recycling is to accelerate degradation process or the breakdown of organic matter by anaerobic bacteria which caused the stages to form methane (CH4) become faster. Therefore, the percentage of methane (CH4) increased. The production of biogas was done by varying the rate of leachate recycling. The variation of rate were 15L/minute and 20L/minute. The result of the study showed that concentration value of methane (CH4) with leachate recycling on 12th day where the rate was 15L/minute was 63,48 % and low heating value was 7669 kkal/kg. Otherwise, the concentration value of methane (CH4) with leachate recycling on 12th day where the rate was 20L/minute was 69,83 % and low heating value was 8436 kkal/kg. Key words: leachate recycling, biogas, methane.
