摘要：A research that analyzed the relationship between biogas production as renewable energy and performance of waste water treatment in tofu small industry using AnSBR reactor has been conducted. This research used system operation method in batches in to get a description of how the biogas production system works as it was operated in the batch mode, which is applied in tofu industry. An instrument capable of operation in batch mode using AnSBR reactor was designed as it does not require sludge re-circulation. An AnSBR reactor includes five stages of; filling, reaction, settling, decanting, and stabilization (idling state). The research was run for 24 days using biogas collected in a tank. Biogas was measured for each HRT starting on the second day HRT to 24thday HRT. Biogas characteristics were monitored on day 16thfor contents of CH4, CO2and heat value. Results show that CH4content in the biogas amounts to 78.26 %, while CO2comprises 20.16 %. Meanwhile, the heat value, which depends on acid methane and CO2content, is 4,246.55 kkal/kg.
