Optimum Co-Digestion Conditions for Methane Production from Chicken Manure and Napier Grass by Single Stage Digention


The purpose of this research was to examine optimum co-digestion conditions for methane production from inoculum, chicken manure and Napier grass by single stage digestion. Combined Mixture Process Design was used to determine the optimum methane production. The experiment consist of different level of 4 factors which were temperature, Inoculums, Broiler and Napier grass in 120 ml bottle with a hydraulic retention time (HRT) of 30 day and total solids (TS) concentration was 15%. The results showed that the maximum methane production was 78% when the temperature was controlled at 40 oC and ratios of Seed : chicken manure : Napier grass was 51 : 6 : 42. The experiment result was validated the optimum methane production by five confirmation experiments which their results were closely agreed with the theoretically predicted value.
