Production Of Ethanol Using Cocoa Pulp Juice

ABSTRACT

 Cocoa pulp were used to produce ethanol using saccrornyces cerevisiae as the yeast during fermentation. The fermentation lasted for 12 days in which such as the acidity, pH, temperature, specific gravity and ethanol which varies due to the difference days of fermentation. The first day the ethanol yield was 1.915% and the last day it yielded 7.150% and pH decreases as the days go by. The titratable acidity at the first day was 0.0250 at the end of the fermentation it increased to 1.0850 which shows that there was a significance difference .
