Abstract

Biogas is one of alternative fuel which is cheap and environment welfare. Component of biogas are CH4, CO2, N2, H2, O2, and H2S. Besides of methane the other content is much in biogas is carbondioxide as a pollutanttha is off 10%-55%. If the carbondioxide in biogas is too much, that can decrease of heat value or biogas quality. Improve of biogas quality can be conducted by way of regulating nutrient ratio and start up pH .The purpose of this reseaarch are to know the methane produced by differences nutrient and start up pH The result of the research are at start up pH 9 methane’s volume is 1823 ml, at start up pH 8 methane’s volume is 523 ml, and at start up pH 7 methane’s volume is 1202 ml.0,013 m3 of  methane is produced per gram ofCODMn removed.At nutrient ratio C/N:P is 43:1 methane’s volume is 523 ml, at nutrient ratio C/N:P is 42:1 methane’s volume is 773 ml, and at nutrient ratio C/N:P is 41:1 methane’s volume is 1823 ml. The best quality of biogas is obtained at the start up pH is 7 and the ratio of C/N:P is 41:1 with methane's composition is 96.64% and carbon dioxide's composition is 2,94%.
