【 摘 要 】

Crab picking waste is a product by process with low economic value. Waste in the form of solid wastes (shell, offal) and waste water (remnants water of crab stew). The amount of waste was generated by one of the fisheries industry Putra Mandiri Mini Plant which causes environmental pollution that has a negative impact on the community. Therefore, good and efficient waste management is needed to be effective and eco-friendly. The waste can be fermented to make gas for the picking product of the biological breakdown of organic waste under oxygen free conditions. This study aims to determine the raw material content of crab waste and the best formula in making biogas. The process of making biogas using different formulation, there are wastes; wastes + cow rumen and wastes + cow rumen + molasses. Then the samples were fermented in aerobic digester for 21 days to produces methane gas. Methane gas is best obtained from anaerobic fermentation processes with crab picking; rumen and molasses waste formulas with ration of 1:1:1 (w/v/v) can produce methane gas of 2.42%.
