Abstract
This research aims to evaluate the effect germination of papaya seeds (GPS) on methane production (batch mode) and the application of GPS in co-digestion (continuous mode). Batch mode study showed that, compare to non-germinated (NGPS), GPS can increase methane production (p < 0.05) by 180 %, 57 %, and 81 % for fresh GPS, fresh GPS meal, and dry GPS, respectively. Methane yields of continuous study were 173.58, 260.71; 269.92; and 329.35 L/kg volatile solid for control; 90 % dairy cow manure (DCM) and 10 % NGPS; 90 % DCM and 10 % GPS; 80 % DCM and 20 % GPS. Germination can increase (p < 0.05) methane production of PS.
