Anaerobic digestion is already an established technology in biogas production which converts biomass feedstock into biogas as a renewable fuel source. During anaerobic digestion, not only renewable biogas is produced but also its by-product can be used as organic fertilizer. The combination of Jatropha press-cake and pig manure has not been fully explored which shows a potential area in biogas production. It was observed that the substrates mix of 50JPC:50PM with water dilution ratios of 1:3 and 1:4, did not produce better results on biogas production. Fortunately, some substrates mix of JPC and PM using the above-mentioned water dilution ratios produced better results in total gas production and methane content. The most satisfactory results of methane gas contents were 172.97, 158.77 and 133.35 L/kg VSdestructed, as produced at substrates percent-mixture ratios of 80JPC:20PM (1:3 WDR), 90JPC:10PM (1:3 WDR), and 90JPC:10PM (1:4 WDR), respectively.
