Abstract

Palm oil empty fruit bunches (EFB) waste contains ±45% cellulose  which can be hydrolyzed into simple sugars using hydrochloric acid (HCl) and fermented into ethanol. The objective of this study was to determine the optimum HCl concentration and hydrolysis time for ethanol production. HCl concentration level used was  2N and 3N, and the variation of hydrolysis time period was 2 hourse and 3 hourse. The hydrolysis product was then fermented using Saccharomyces cerevisae. The results showed that the optimum condition of  EFB hydrolysis was obtained from concentration 3N HCl  during 2 hourse process with 16,34% of reducing sugar. The optimum ethanol content was 0.30% which was abtainst after 3 day process. Mean while the optimum of  carbon dioxide (CO2) was reached on the three day.
