摘要：The circular economic scheme is applied to utilize the waste cooking oil from semarang barat resident area as raw material of biodiesels, the results shown that biodiesels production was able to produce 82.54% of biodiesels yields and analyzed refer to Keputusan Direktur Jendral Minyak dan Gas Bumi No.13483K/24/DJM/2006 specification including FAME concentration, Flash Point, Density, Viscosity and calorie value. Based on the analysis, the biodiesel produced has the potential as a substitute for diesel oil used for boiler fuel. This scheme is able to generate net income of IDR 135,542,430 per year from the biodiesel utilization on the difference of diesel oil utilization for boiler fuel and IDR 14,928,656 per year from crude glycerol sales.
