Abstract:
This study aims to determine the best levels of bioetanol from a combination of
bagasse and banana peel mixtures with 6 gram yeast mass and 72 hours, 96 hours
and 120 hours fermentation time, to determine the optimum fermentation time and
to know ethanol levels according to SNI. This research was carried out by
hydrolysis or boiling of bagasse and banana peel to break down the molecules into
two parts, then the fermentation process was carried out using Saccharomyces
Cerevisae (yeast) and the distillation process was carried out using a destilator to
obtain ethanol from fermentation which was then tested by means of Pen
Refractometer to find out whether there is an ethanol level formed from the
distillation process. The best sample selected was then tested for ethanol content
using the Gas Chromatography tool. So that the best ethanol yield that can be
categorized as achieving in SNI is a combination of 100% bagasse – 0% banana
peel with 6 gram yeast and 96 hour fermentation time of ethanol produced at
95.53%.
