Bioethanol production from durian shell wastes by saccharification and liquefaction processes

Author(s): Irhamni, Dewi Mulyati, Diana, Saudah
Abstract: Durian shell wastes can serve as the main raw materials for advanced fermentation in bioethanol manufacture and can be used for wider applications to generate renewable fuels for industrial and rural communities in developing countries. This paper aims to study the process of bioethanol production and to look at the proper saccharification process for further fermentation which produces good bioethanol. The fermentation was observed for 48 hours. Enzyme α-amylase and glucoamylase are used in the process of saccharification and liquefaction to produce bioethanol. The results showed the fermentation of durian shell wastes was at pH 4.5that became the maximum percentage of bioethanol production and was the highest ethanol content in water that is equal to 16,69%. The purity of bioethanol was analyzed using GC-MS and the highest peak of chromatogram reached 96.99% at 2,163 minutes which was detected as the first peak of bioethanol. The second peak of acetic acid reached 3.01% at 13,279 minutes. The purity of bioethanol that can be used for fuel should be 95% so this bioetahnol could replace premium. It is concluded the durian shells are very well used as an alternative fuel and the shells are renewable in nature as well as environmentally friendly for motor vehicles.
