Abstract

Waste product in Indonesia is still a crucial problem where it is increasing every day in accordance with the citizen population. The absence of waste management, especially organic waste, causing bad impact on health such as infectious diseases and water pollution due to the decomposition of organic waste into organic acid or methane. The problem of sewage coming from the food waste can be overcome by using a fermentation process in anaerobic reactor which products bio-hydrogen gas and organic fertilizer. Bio-hydrogen gas produced can be used as a source of renewable energy in which hydrogen gas has advantages when used as a fuel does not produce carbon dioxide, but only water vapor. In the research that has been done hydrogen has been produced depend on variation of rice content in food waste with grading 47.1% of the total gas produced to the highest levels of rice. Further studies using an anaerobic reactor with the addition of temperature control, pH, and substrate particle size and the expected product gas produced with a greater percentage of hydrogen gas.
