EKSISTENSI WAKTU FERMENTASI TERHADAP RENDEMEN BIOGAS MENGGUNAKAN GREEN PHOSKKO® (GP-7)

Time Existence of fermentation Against To Biogas Yield By Using Green Phoskko ® (Gp-7) (Agustiawan, 2014, 53 Page, 12 Table, 21 Picture, 4 Appendix) Large consumtion of energy makes the energy reserved become lower, for it to need alternative renewable energy, saving energy and enviromentally friendly, is using of biogas. Biogas is a gaseous fuel produced from fermentation of organic materials with the help of anaerobic bacteria that can be used as an alternative energy. In producting of biogas partition reactor type that uses waste vegetable raw materials by adding cow dung as an early starter. Biogas production is done by adding green Phoskko (GP-7) as a medium to accelerate the bioconversion of organic matter degradation process. Biogas fermentation process carried out for 13 days. Biogas produced biogas composition was analyzed to determine the highest during the fermentation process. From the analysis and calculation result biogas yield in optimal conditions at the 12th day 4,99% and calorific value (LHV) 8435kkal/kg. Keywords: vegetable waste, time, yield, green phoskko, LH
