Abstract

Indonesia is a country that has large, widespread and diverse renewable energy potential that can support energy transition and achieve net zero emission (NZE) target by 2060 or sooner. This paper aimed to investigate characteristics of exhaust emissions and consumption fuel of biogas-fuelled electric generator. The biogas used comes from organic cow dung through an anaerobic fermentation process. About 40% vol. CH4 content observed in biogas. A 420 CC of single cylinder generator was used in this study. Based on the results, it can be seen that biogas exhaust CO emissions are relatively lower than gasoline. CO emissions are directly proportional to the electric load. The lowest CO2 emission was obtained at 4,7 % for biogas with 300 W electric load and 8,4 % for gasoline which is the highest emission. The concentration of hydrocarbons was observed to be 20 ppm for biogas while 64 ppm for gasoline with 300 W electric load. For the fuel consumption, biogas obtained relatively higher results than gasoline for each electric load.

Abstract

This study evaluates the potential of rice husk waste as a renewable energy source in Bali Island. Based on rice husk production data of 127,095 tons per year and an average calorific value of 14 MJ/kg, the estimated energy potential reaches 494,258,728.74 kWh per year. This amount is sufficient to meet the electricity needs of approximately 41,188 households, assuming an average consumption of 100 kWh per month. The evaluation results indicate that rice husks have strategic value as a local biomass resource that can be utilized through various technologies, such as direct combustion, gasification, and biomass briquetting. In addition to reducing dependence on fossil fuels, this utilization supports sustainable agricultural waste management. Therefore, an integrated approach involving policy support, appropriate technology, and community engagement is essential to effectively and sustainably implement energy utilization from rice husk waste in Bali and other agricultural regions in Indonesia.
