Abstract:
This study aims to determine the best bioethanol levels from a combination of
bagasse and banana peel mixtures with variations in yeast mass of 4 grams, 6
grams and 8 grams with a fermentation time of 60 hours, to determine the
optimum yeast mass and to determine ethanol levels according to SNI. This
research was carried out by hydrolysis or boiling of bagasse and banana peel to
break down molecules into two parts with distilled water, then the fermentation
process was carried out using Saccharomyces Cerevisae (yeast) according to the
specified variation and the distillation process was carried out using a destilator to
get ethanol from fermentation then tested with a Refractometer Pen to find out if
there is ethanol formed from the distillation process. The best sample selected
then tested the ethanol content using the Gas Chromatography tool. So the best
ethanol yield that can be categorized as achievement in SNI is a combination of
75% bagasse - 25% banana peel with the addition of 8 grams of yeast and ethanol
produced at 96.64%.
