Abstract
The global oil energy crisis is caused by the imbalance between consumption and production of petroleum. In order to compensate for this imbalance, the conversion of organic waste and biomass into fuel is carried out appropriately and quickly. This review article aims to determine the potential for solid waste from oil palm, Oil Palm Empty Bunches (TKKS) and Palm Oil Palm Ribs (PKS) as raw materials for making bioethanol. The production process of ethanol from palm oil solid waste is carried out starting from lignocellulosic pretreatment using alkaline and oxidation methods, with the highest results getting a decrease in lignin content in the EFB substrate from 35.51% to 9.47% or a decrease of 73.33%, while cellulose and hemicellulose content increased by 69% and 20.68% respectively, then the hydrolysis process with acid and enzyme catalysts with the highest yield obtained glucose levels of 60.02%, followed by a fermentation process using Saccharomyces Cerevisiae with the highest yield of ethanol content of 7.93%. Utilization of empty oil palm fruit bunches (TKKS) and oil palm midribs (PKS) as raw materials for the manufacture of bioethanol has enormous potential.
