Effect of Time and Concentration of Sulfuric Acid on Yield Bioethanol Produced In Making Bioethanol from Peat Soil

Abstract

The depletion of petroleum reserves, the price of fuel oil (BBM) which tends to increase, and environmental safety reasons encourage the search for other materials to be made as raw materials for making bioethanol. One of the most potent ingredients as raw material for making bioethanol is lignocellulosic biomass. Lignocellulosic biomass consists of three main components, namely: lignin, cellulose, and hemicellulose. Cellulose and hemicellulose are sugar polymers which can be broken down / hydrolyzed to produce sugar and then fermented into bioethanol. One of the lignocellulosic biomass that can be used as a substrate for bioethanol production is peat. This study will review the effect of the delignification process and hydrolysis of the yield percent of ethanol produced in bioethanol production from peat soil.
