Bioethanol Production from Mixture of Banana and Durian Peels

Abstract

Bioethanol is ethanol produced by digesting sugar from carbohydrate sources with the assistance of microorganisms. This study was divided into four stages: durian and banana peel pre-treatment, hydrolysis, fermentation, and distillation. Banana and durian peels were mixed with a blender to make flour, then dignified with 1% NaOH and heated in an autoclave for 30 minutes at 120 o C before being cooled and stored. The pre-treatment results were mixed in an Erlenmeyer, then 1% H 2 SO 4 sulfuric acid was added and heated in an autoclave for 45 minutes at 120 o C for the hydrolysis stage. At the fermentation stage, 30 g of cultured yeast (Saccharomyces cerevisiae) and nutrients were added to a hydrolyzed mixture of banana skin pulp and durian peel, which was then fermented for 6 days. The fermented solution is placed in the distillation flask during the distillation stage. The temperature is kept between 70 and 80 degrees Celsius. The distillation process took 1.5-2 hours until the ethanol ceased leaking, after which the distillate findings were measured. The variable ratio of banana peel : durian peel was 100:0 yielding the most significant results in this trial, with an ethanol production of 0.01485%.
