PEMANFAATAN LIMBAH AMPAS TEBU (BAGASSE) UNTUK PRODUKSI BIOETANOL MELALUI PROSES SAKARIFIKASI DAN FERMENTASI SERENTAK

Abstract

The aim of this research is to describe the process of bio ethanol production from
bagasse with simultaneous sacharification and fermentation.
The subject of this research was bagasse. The object of research was the amount of bio
ethanol from fermentation of bagasse using Sacharomyces cerevisiae. The independent
variable in this research was the concentration of yeast in the fermentation. There were
0.4%; 0.6%; and 0.8% of solution weight. The chemistry analysis in the research was a
quantitative and qualitative analysis of ethanol using Micro Conway Diffusion and spectronic
20.
The results showed the yeast concentration of 0.4% by weight solution of the hydrolysis,
ethanol result was 24.555%. In the yeast concentration of 0.6% by weight of hydrolysis
solution, the ethanol content was 39.571%. In the yeast concentration of 0.8% by weight of
hydrolysis solution, 35.005% of ethanol was obtained. It was the highest level of ethanol on
yeast concentration of 0.6% by weight solution of the hydrolysis.
