Evaluation of a Small-Scale Anaerobic Digestion System for a Cattle Farm under an Integrated Agriculture System in Indonesia with Relation to the Status of Anaerobic Digestion System in Japan

The Integrated Agriculture System in Indonesia was established 2009. By the end of 2018, 752 small-scale anaerobic digestion (AD) systems treating beef cattle manure were successfully installed. In this study, system studied comprehensively at first attempt by considering current operating conditions, actual performance digester, and site-specific factors for biogas production. Compost bio-urine produced approximately 0.13 t/day 4.8 L/day, respectively. digester an unstable amount 0.109 to 0.521 m3/day. However, Japan produces 980 This observed difference due inputs technological peculiarities. main purpose installation AD also different. Producing compost aimed Indonesia, while producing reducing sawdust usage target Japan. Thus, study suggested that monitoring controlling operational parameters could increase production as a step without installing any additional temperature controller or mixing equipment. approach might be useful improving quality providing stable treatment conditions.
