Abstract

PT Lautan Warna Sari (LWS) which produces modified starch-based raw materials at 200 tons per day can now use biogas as energy alternative. The high content of waste biomass has high economic value when processed into biogas. Proper waste handling only slightly remove the odor. Based on field observation, the formation of gas as characterized by the emergence of gas bubbles arising from the equalization basin. It raises the idea for managing and processing of waste into biogas. Biogas reactor (digester) models are made of plastic polyethylene balloon mounted on the anaerobic pond and placed half buried in the ground in order not to be separated when the product reaches the peak bio gas. Biomass intake holes and drain holes arranged to prevent blockage. The prototype digester used balloon model with a capacity of 17000 m³, biogas purification unit is equipped with a capacity of 5.8 m³ minˉ¹. The application of biogas as modified starch product dryers can replace the diesel fuel. The best production capacity of 4.6 m³ minˉ¹ in biodigester occurred at 35˚C temperature condition. The ratio of waste discharge to the flow of wash water utilizing the cassava as eddy currents was 1:0.5 and was capable of producing 42% methane gas. Moreover, purifying the biogas increased the methane gas content up to 73%.
