The biodigester is a tool used to process organic matter into biogas and is a solution to manage the accumulation of organic waste. Piles of garbage, if left un-cleared, will have a negative impact on the environment in the form of water and soil pollution, and damage the aesthetics of the environment. This study aimed to create combination model of biodigester and composter in managing organic waste into biogas and compose. We focus to discuss about the parameters of observed in biodigester. This study method is a laboratory experiment. The reactor was deployed continuously, using a heater with a temperature of approximately 55-60 ºC and stirring between 100 rpm. The reactor temperature could be adjusted according to the living conditions of the thermophilic bacteria used at a temperature of 45-65 ºC and installed in an integrated manner with the fermenter. The study method on pH parameters is APHA 4500-H, chemical oxygen demand (COD) with spectrophotometry, total solid (TS) with APHA 2540B, volatile solid (VS) with APHA 2540E method, total suspended solid (TSS) with APHA 2540B method and volatile suspended solid (VSS) using the APHA 2540E method. The study results on HRT 10 with pH 7 showed an average yield of TS, VS, TSS, VSS, COD, and Alkalinity amounting to 31.613, 22.125, 12.629, 10.713, 17.625 and 4.481 mg L-1, respectively. This study proposes a new combination model of biodigester and fermenter which is effective in manufacturing biogas and compost from organic waste.
