Abstract

Indonesia is the leading country of palm oil producers, it reaches a total area of 12.5 million hectares plantation. It generates excessive wastes as well. Oil Palm Frond contributes to 61% of it. OPF could be used as a substrate to produce bioethanol because of its high sugar content. The objective of this study is to find the best method and condition to use OPF as bioethanol fermentation raw material. The methodology used in this study is literature review. There are 2 ways to process OPF. First method consists of physical pretreatment of milling and drying the OPF, to obtain the fibers before it goes to chemical pretreatment, which includes soaking it in acid or alkaline solution, subsequently fermentation using Saccharomyces Cerevisiae. Another method, fermentation is carried out on the juice obtained by simply pressing the OPF. From all the research reviewed, the best method is using the juice pressed from OPF. The juice consists of approximately 77.69% sugars. The OPF should be from an oil palm tree with the age of 3 – 4 years to have the optimum sugar content. Also, OPF that is directly connected to the inner part of the trunk have the possibility to contain more sugars than other fronds.
