Effect of Adding Palm Oil Mill Effluent (POME) and Slurry on Biogas From Cow Manure to Produced Methane Gas

Biogas is a renewable energy source that is environmentally friendly and economical. High of Palm Oil Mill Effluent (POME) and cow manure have great potential as a source of raw material for making biogas. The purpose of this study was to determine the effect of the addition of POME and biogas slurry to the production of biogas from cow manure raw material. The composition of raw materials used are 40 L cow manure, 20 L water, 20 L POME in the first experiment and 40 L cow manure, 20 L water, 20 L biogas slurry in the second experiment. The composition of methane gas was analyzed using the Gas Chromatography. From the results obtained, the addition of POME produced 64.65% of methane gas with biogas production of 54 L and the addition of biogas slurry produced 53.83% of methane gas with biogas production of 58 L.
