Production Of Bioethanol From Corncob And Sugarcane Bagasse With Hydrolysis Process Using Aspergillus niger and Trichoderma viride

Abstract

Abstrack : Bioethanol is an alternative fuels derived from biomass that is more environmentally friendly and renewable. Corncob and sugarcane bagasse are a potential agricultural wastes used as raw material for bioethanol because it has a high carbohydrate content and abundant availability. The efforts to increase bioethanol production performed by enzymatic hydrolysis method using fungus cultures of Aspergillus niger and Trichoderma viride. This study aims to determine the best combination of the addition of A. niger and T. viride cultures on corncob and sugarcane bagasse raw materials which produces optimal bioethanol production with high substrate efficiency and low residual sugars content. The results showed that the use of corncob raw materials with the addition of Aspergillus niger culture is the best treatment combination that produces ethanol at 282,3 ml/kg with 90,35% substrate efficiency. While the bagasse raw material, the addition of Trichoderma viride culture is the best treatment combination that produces ethanol at 299,2 ml/kg with 90,95% substrate efficiency.
