Food Waste Composting with The Addition Of Cow Rumen Using The Takakura Method and Identification of Bacteria that Role in Composting

The purpose of research to measure and analyse the quality quantity food waste composting by adding cow rumen activator efective microorganisme (EM4). This do identify dominant bacteria that play a role in composting. method applied this is Takakura for bacterial identification was referred as Bergey's manual which consisted gram stain test biochemical test. Three types composter variation are being use composting, 1 consist (food maturecompost), 2 waste, mature compost EM4 activator) 3 activator). parameter include maturity, (moisture content, temperature, pH, texture, color, C/N ratio, P K), compost. results showed not all variations met maturity qualitybased on SNI 19-7030-2004 standart such organic carbon 1B ratio 1A 1B. affects addition activators give short time good Composting with fastest 7 days ratiois 19.22%, 0.34%, Kis 2.08%. EM 4 occurred 8 20.53%, 0.30%, K 1.82%. without longest 11 23.74%, 0.21%, 1.76%. show cow's best score 15. some Bacillus sp degrade matter.
