Abstract

Human’s increasing activity causes an immense increase in domestic waste. one form of domestic waste which could harm environment is vegetable waste. in this research, vegetables waste is used as based material of liquid compost. The process of producing liquid compost with vegetables waste as the base materials was using EM4 fermentation method as a starter and zeolite 80-100  mesh as the bind for soil nutrient in liquid compost. In the fermentation process, the researcher conducted 3 different behaviors in adding EM4 and Zeolite, in each 10 gr, 20 gr and 30 gr of EM4; and 40 gr, 60 gr and 80 gr of Zeolite. The fermentation process was conducted  in 40 days. The liquid compost samples were analized for pH, C-Organic, N-total, P-total and K-total. The results showed that highest concentrate of soil nutrient was from the adding of 30 gr EM4 and 80 gr Zeolite in which the result was 0.27% C- organik, 0,07 %  N-total, 0,04 % , P-Total dan 0,46 %  K-Total.
