Abstract

Bukittinggi city with approximately 132 industry crackers Sanjai spend 300-500 kg of
cassava per day for each industry. Solid waste production process results Sanjai crackers this
one is skin cassava. Cassava’s peel produces 15-20% carbohydrate content of 68-85% of the
weight of the bulb, so it has great potential to be converted into bioethanol.
Carbohydrates in the tuber peel can be processed into ethanol by fermentation and for separating
ethanol from it’s mixture used method of distillation. Distillation temperature and time used
affects the quality and quantity of bioethanol produced. This study aims to determine the best
time and temperature distillation to produce bioethanol at the highest levels. Ethanol content
analysis was conducted using the specific gravity using line arregression equation and Table
gravity of Indonesian Pharmacopoeia. The results showed that the highest levels of ethanol
distillate obtained in the distillation temperature of 71o C for 5 hours is 16.60% using regression
methods and 14.1% according to Table Pharmacopoeia with yield ranging between 2.30%-
5.80% and the efficiency of distillation 28, 94% -57.50%. Time and temperature distillation
have a real impact on the levels of ethanol produced atthe level of 5%.
