It had been conducted a study on the making ethanol from nypa sap (Nypa
frutican Wurmb) with fermentation process. This study aimed determine the
amount of ethanol produced from nypa sap and to the amount of yeast that cauld
produce the optimum ethanol. In this fermentation using yeast (Saccharomyces
cerevisiae). To determine the amount of ethanol produced was carried out by
weighing the gravity of ethanol destlilled using piknometer.
The result of this study showed that ethanol could be produced from the
nypa sap in the amount of 5 to 6% without significantly influence by the amoun of
yeast used.
