Abstract
This research aims to evaluate the performance of homemade bio-activator in processing household food waste through a semi-continuous process. It used a 214 litres capacity of an anaerobic digester that serve 8 households. Performance of digester with homemade bio-activator was compared to other commercial activators including Green Phosko (GP7), Effective Microorganisms 4 (EM4) and one digester control without activator. The pH of household food waste was set at a neutral using limestone, while the weight ratio of water and the waste was set at 2:1. There were 2 processes conducted, namely the preparation stage (batch process) and operational stage (semi-continuous process). The first stage means preparation for microbial activity in anaerobic conditions, while the latter stage means a biogas production process. Digester with homemade bio-activator displayed the best performance compared to other variations. The digester produced cumulative volume biogas of 335.7 L with methane gas production of 1.29 L/kg total solid or 1.52 L/kg of volatile solid.
