Abstract

ABSTRACT. The objective of this research is to evaluate economic benefit and greenhouse gas (GHG) emission reduction potential of a family-scale anaerobic cowdung biogas digester. Research was conducted at two villages in Lampung Province, namely Marga Lestari, District of South Lampung and Pesawaran Indah, District of Pesawaran. Economic benefit and GHG emission reduction potential were evaluated based on LPG saving due to biogas utilisation for cooking and slurry digestate utilisation for fertilizer substitution. Results showed that a family-scale anaerobic cowdung biogas digester demonstrated a good potential to reduce GHG emission, but not in economic. A digester with 5 heads of cow produced biogas at a rate of 1582 L/day. With average methane content of 53.6%, energy value of the biogas was equivalent to 167 kg LPG and able to substitute 52 bottles LPG annually. A family-scale biogas digester contributed 111.6 USD/year and potentially reduced GHG emission by 2674.8 kg CO2e/year. Development of family scale biogas-digesters should be integrated with organic fertilizer production and smallholder agriculture.
