Abstract

The kepok banana hump waste contains 76% of starch and patent production of bioethanol biosphere is biomass ethanol and acts as alternative energy instead of oil fuels. The study aims to determine the comparison of methods of Simultaneous Saccharification and Fermentation (SSF) and Separate Hydrolysis and Fermentation (SHF) %yield and the influence of raw materials masses on %yield. The study uses the process of enzymatic hydrolysis, the enzyme used in the hydrolytic process of α-amylase to break starch into a complex sugar with temperature 95˚C for two hours and the glucoamylase to break the complex sugar into a simple compound of 66˚C for three hours after which it is sterilized for 30 minutes using an autoclave device to kill bacteria. Then supported to convert sugar into ethanol at temperature. the mass used is 50 and 100 grams and concentrations of α-amylase enzymes, glucoamylase, and alcoholics by 10 (b/b) and was then dissented according to the 78˚C ethanol dedication to get mummified ethanol. Improved results include SHF and %yield methods extracted from raw materials of 6,4% and 1,5% respectively while the kepok banana hump mass. The best group banana from the SHF and SSF methods is 50 grams with an %yield  produced by 6,4% and 3,2% respectively.
