Abstract
The great need for energy and the problems of environmental pollution make it necessary for the use of bioethanol as an alternative energy produced from renewable and eco-friendly resources. Sorghum can produce sugar, grain, bran and biomass which can be used as raw materials to produce bioethanol. The present study used the bran and biomass which are sorghum waste to produce bioethanol. The process of bioethanol production from bran and sorghum waste consists of a number of stages including pre-treatment using NaOH, hydrolysis, fermentation, and two step distillations finally produce bioethanol 99% used for fuel. Conditions for pre-treatment and hydrolysis are made varied at 24 hrs., 48 hrs. and 72 hrs. in order to maximally produce bioethanol. Fermentation was carried out using the yeast of Saccharomyces cerevisiae. Based on the results of this study, it is expected that sorghum which can be grown easily in Indonesia especially in rural areas can be utilized both as a resource of energy.
