Abstract :
At this time the sweet orange peel still not get the handling significantly.
Because sweet orange peels are generally ignored and thrown away in the trash. But
peel containing cellulose can be used as raw material for the manufacture of
bioethanol alternative. Bioethanol is ethanol made from organic materials. Sweet
orange peel is used as an alternative feedstock to manufacture ethanol using
hydrolysis, fermentation and distillation. In the process of hydrolysis given variable
100,150,200 gram heavy orange peel. Hydrolysis using HCl acid solution is best
obtained sugar levels by 1.458% to as much as 200 grams of orange peel. Solvent of
fermentable sugar from hydrolysis with variable length 3,5,7 fermentation time, days.
Is derived from the fermentation process of the highest levels of ethanol is equal to
0.195% on the fifth day with a weight of 200 grams orange peel. After that ethanol is
destilled at a temperature of 70°C for 1 hour and ethanol obtained with the highest
levels of 0.054% using fermentation of an alcoholic solvent of 0.195%.
