Abstract

Ethanol is a colorless clear liquid, volatile, has a pungent aroma and a patio painful skin. In the world of education the ethanol is used as a disinfectant and solvent in various studies, besides that ethanol can also be a source of energy to overcome the energy crisis. In previous studies of soybean husk waste tempe production which has been a waste and can be raw material for ethanol fermentation process. The purpose of this research is to increase ethanol soybean husk production, by controlling the temperature and pH of the fermentation process. The research was conducted in the ITP FPP UMM laboratory by controlling the fermentation temperature at temperatures 30oC, 35oC, 40oC and pH 4.5, 5, 5.5. The parameters measured were the levels of ethanol, reducing sugar and pH changes during fermentation 12, 24 and 36 hours. The results showed that the treatment temperature is 30oC with pH 4.5 produce ethanol with the highest levels of 4.071% at the 36. while the production of ethanol using the fastest treatment at 40 oC ph5, 5 at the 12 with 2.748% ethanol levels but decreased thereafter.
