Peningkatan Agribisnis di Pedesaan Melalui Pemanfaatan Bekatul untuk Produksi Bahan Bakar Bioetanol dalam Mewujudkan Ketahanan Pangan

Abstract

Carbohydrate biomass is considered as the future feedstock for bioethanol production because of its low cost and its huge availability. One of the major carbohydrate materials found in great quantities to be considered, especially in tropical countries, is rice bran. The effect of different pH and temperature with enzymatic saccharification treatment on conversion of rice bran was studied. Finally the sample was fermented using Saccharomyces cereviceae yeast and the amount of produced bioethanol was measured. Enzym treatment at 60ºC and pH 5 is an effective treatment method for converting rice bran to glucose. Up to 22.75% glucose v/v could be achieved after enzyme treatment. Fermentation of treated rice bran shown that glucose after 3 days fermentation the maximum bioethanol of 17.31% (v/v) was attained.
