Abstract

one source of material that has high potential to be proceed become biogas is tofu liquid waste.The composition of tofu liquid waste mostly consist of dissolved and insoluble solid particles amounting to 0,1%. Solid particles of organic substances (± 70%) and inorganic substances (± 30%). Organic substances consist of protein (± 65%), carbohydrates (± 25%), fat (± 25%). This research focus on processing liquid waste from the tofu industry into biogas by codigestion using cow dung in a fixe dome type biodigester by finding the optimum fermentation time to produce biogas. From the research results, with the characteristic of Tofu waste with COD of 11.105 mg/l and TSS 1938 mg/l, it was found that the optimum time for codigestion of tofu liquid waste with cow dung was 20 days, with a CH4 content obtained from biogas of 50.32%, CO2 content of 11.78% and H2S of 256 ppm..
