Abstract
One of the natural resources that can be utilized alternative into bioethanol is
palm sap. Preparation stater done by culturing medium Saccharomyces
cereviseae as developer on 10% yeast fermentation medium thus able to adapt
and be ready to do the fermentation. This study aims to make bioethanol from
palm sap 50-liter scale with variations in pH 4,5; 5 and 5,5 and fermentation time
24, 36, 48, 60 and 72 hours.. Batch fermentation process takes place with a
stirring speed of 200 rpm and temperature of fermentation at room temperature
(25-300C). The optimum fermentation conditions indicated on the initial
conditions of pH 4,5 and fermentation time of 48 hours the acquisition of or 9% .
