Daftar Isi:
- Banana peels, once only a waste, can be used as biomass sources. Banana peels contain enough carbohydrate which can be used as carbon sources in ethanol production. In this experiment, banana peels were hydrolized by HCL 37% in pH 1. The hydrolysis was done on temperature of 50, 60, 70, and 80oC in 60 minutes. After that they were fermented by Saccharomyces cereciceae with variable of nutrient Diammonium phosphat 10, 20, and 30 gr/l in 12 days. Result showed that the optimum ammount of glucose was 83,021 gr/l. It was obtained from hydrolysis of 70oC in 60 minutes. Conversion carbohydrate to glucose reached 91,2% mole. Fermentation product decreased when concentration of ethanol reached 5,32%v. The optimum ammount of ethanol was 314,46 gr ethanol/ kg dry banana peels, obtained from the 8th of fermentation.
