Organic waste is the waste residue of a material that has been thrown away, but its existence can still be utilized. So far, organic waste from traditional markets is directly disposed of in landfills. Even though organic waste if left uncontrol cause unpleasant odors, it can also cause environmental pollution because organic waste can be destroyed by itself so that it will absorb into the soil which can cause pollution to groundwater infiltration. Nutrients contained in traditional market waste can be combined with animal manure that is cow manure and chicken manure, so this research will produce alternative biogas energy, it can be used in daily life. The decomposition of organic matter with a fermentation process by microorganisms on the material which takes place anaerobically to produce methane. This study uses a variety of ingredients that have been determined to find the maximum concentration with the best results.
