| Summary: | Energy is the basic requrement of the human life. More people development will be more
energy requirement needs. During the time, using the energy unrenewal that become causes of energy
crisis in the future. The solution to solve this problem is by unceasing research related with the
alternative energy that can be renewal (bioenergy), one of them is bioethanol. Bioethanol is an easy
result of burn material from plants fermentation contains of glucose, carbohidrate, or cellulose. The
materials were found from the food materials as the main factor for the people. The effort to avoid
competition between the stock of food materials and the source, so the alternative is make bioethanol
from compose heap of food production example nata de coco�s waste. This observation is to analyzed
wether potential or unpotential from compose heap of nata de coco to be the substitude material of
bioethanol. From thus observation hopely can find many benefit like knowledge of the result and
process from the waste to be beneficial matter and minimize waste contamination to enviroment.
The observation start from splitting up the material cellulosa chains being glucose using
ezyme to produce higher sugar reduction, then the media will be fermentated to be bioethanol. The
fermentation using S.cerevisiae in the accurate propper time and then will be distilating till produce
etanol. Technically the solid waste of nata de coco potentionaly to be bioethanol, because reduction
sugar from sacarification process could be fermentated with S.caerevisiae. Sugar reduction from nata�s
waste are 0.86% and be 0.68% bioethanol. Product bioethanol from nata�s waste have a very small
content so unpotential to be substitution of BBM commercially. Other than that, bioethanol from
nata�s waste have a high production cost and lack of stock material.
