Abstract
Biohydrogen is one of promising alternative renewable energy sources. This can be produced through sugar fermentation in anaerobic condition. In this research, the potential of biohydrogen production from molasse using cow dung as inoculums is investigated. The biohydrogen was produced through fermentation of molasse in serum vials at varied initial pH (3, 5, 7) and fermentation (2, 3, and 4 days). The cow dung was preheated at 105oC and 2 hours prior to inoculation. The final sugar concentration, MLVSS, volatile fatty acids (VFAs), alcohol content (ethanol and butanol) as well as the gas production rate were analyzed at the end of fermentation. The presence of Clostridium perfringens in the inoculums had been detected. The highest biohydrogen yield was 3.065 mole H2/mole of substrate. The potential of the biohydrogen produced to produce lectricity was tested using fuel cell. It was found that it can produce 11.477 W.
