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% .  Keywords: Bioethanol, palm sap, fermentation, Saccharomyces cerevisiae
