Abstract

It is about 2.64 tons per day of organic waste is disposal by 8.470 residents of Nogotirto Gamping Village Sleman Yogyakarta. The odor of the waste is very disturbing for the neighborhood when the waste untreated well. Thus, it is important to treat the waste properly in order to encounter the problem. The present work aims to develop Biosam digester which is used for converting organic waste into useful renewable energy ^biogas^. The present work also objective to fundamentally examine optimization characteristics organic matter degradation of organic household waste by anaerobic method and utilizing cow manure in biogas production. Utilizing microorganisms from cow dung is an innovation and is the novelty of this research. Removal of organic material is unique because it is facilitated by two factors. The first factor is the amount of concentration microorganisms from cow dung that function as decomposers of organic matter and controller removal selectivity to degrade organic matter. The second factor is the HRT is the average period required for the substrate to react with the bacteria methanogen in digester. The results shows that the 10 m3 biosam digester is able to be built using simple and low cost in Nogotirto Gamping Village and able to generate biogas which has been used for cooking fuel by neighboring household.
