Abstract

Oil Palm Empty Fruit Bunch is one of lignocellulosic biomass that has potential to be utilized as a source of renewable energy such as bioethanol. In order to increase profitability, hydrolysis of hemicellulose can be considered to produce high value chemicals such as xylitol. Xylitol is the result of degradation of xylose. This research main to obtain high yield of xylose by doing enzymatic hydrolysis to break down hemicellulose by using diluted sulfuric acid for pretreatment process, different pH and the ratio between Cellic® Ctec2 and enzyme Cellic® Htec2 on enzymatic hydrolysis process. After undergoing pretreatment process, xylose yield was 25.06% on dry basis. The optimum condition for enzymatic hydrolysis with temperature 50C using 150 rpm, was found to be with enzyme ratio of Cellic® Ctec2 and enzyme Cellic® Htec2 1:5 and pH 5.5 after 12 hours. The release yield of xylose and glucose respectively was 78.95% and 14.25% at dry basis.
