Abstract

The anaerobic digestion (AD) process from organic waste is often unstable due to the high concentration of Volatile Fatty Acids (VFAs). The purpose of this research was to determine/evaluate the production of methane using biochemical methane potential (BMP) test with two substrate combinations, consisted of organic waste and cow manure as buffer. BMP test conducted for 35 days at a temperature of ± 35°C by measuring the volume and concentration of biogas every week and testing the sample characteristics before and after the test. The result of the sample variation showed there was no significantly difference of methane volume in the 5th week except the variation of organic waste/cow manure: 12/1 to 3/1, but the sample with a ratio of 3/1 yielded the highest methane potential of 0,58 ± 0.015 (n = 3) LCH4/gr Volatile Solid. The addition of cow manure stabilized the condition of all variations during BMP test with VFAs/alkalinity <0.3 although Carbon/Nitogen ratio of each variation is <20.
