Organic waste dominates the waste composition percentage in Bandung city. If not managed properly, organic waste can be one of the main causes of climate change due to greenhouse gases released during the process in landfill. Therefore, organic waste processing at the source is required. One of the major contributors to organic waste production in the city of Bandung is the culinary sector especially food waste production. This food waste processing experiment carried out using the techniques of anaerobic digester using cafeteria kitchen waste as input. Research conducted on one day of the kitchen waste generated, using batch system reactor with the capacity of 13 liters in three sets of reactors; Reactor A, B1, and B2 varying in aerobic pretretment techniques. Physical and chemical characteristics of the kitchen garbage showed the sample has water content percentage of 81.24% and volatile content of 78.61% shows the kitchen waste sample is potential to be processed using anaerobic digestion technique, although the pH and the C / N ratio respectively at 4.5 and 50 still in need of adjustments before the sample is processed. Preliminary results of the research showed removal of volatile, organic carbon, and NTK but not in it’s optimal result due to the lack of stability of the pH during the process. The latest monitoring of the biogas production shows values as in Reactor A 0.006 m3 / kg-VS, Reactor B1 0.012 m3 / kg-VS, and Reactor B2 0,007 m3 / kg-VS with methane gas percentage at 11.5%, 36, 0%, and 22.5% for each reactor.
