Abstract

Organic waste should be used to minimize environmental problems. Organic waste can be mixed with Saccharomyces cerevisiae and cows manure as a raw material of biogas production. Appropriate Saccharomyces cerevisiae dose and cows manure are needed to get the best biogas production with distillery sludge as fertilizer that meets the standards. This research is aimed to determine whether organic waste utilization with addition of Saccharomyces cerevisiae and cows manure provides good biogas production. Research was done experimentally based on Completely Randomized Design 4 x 3 with factorial patterns. Treatments consisted of three factors, namely the addition of different Saccharomyces cerevisiae concentrations (0 gr, 2 gr and 4 gr) and combination of organic waste and cows manure ratio (1:0, 2:1, 1:1, 1:2 v/v) with three replications. The result showed that 2 gr of Saccharomyces cerevisiae on kitchen waste and cows manure with ratio 1:1 (F2S1) can produce 0,0128m3 with a decrease in the C / N ratio of 60.07% and the final pH of sludge 6.81.
