Abstract

After peeled, cassava bark is usually just thrown away or being used for fodder. Cassava bark mainly consists of carbohydrate, and potentially to convert it to be glucose by acid hydrolysis. The objectives of this research are to determine acid concentration, reaction time and temperature effects to glucose-yield. The experiment was developed in three-necked bottle equipped with thermometer, stirrer and heater. Hydrochloric acid was used as catalyst. The higher concentration of the acid gave the higher concentration of glucose. It was the same as the effect of time and reaction temperature. The highest glucose concentration was resulted on 0.1 N hydrochloric acid concentration, at the boiling point and 60 minutes reaction. The reaction rate constant was 0.0003/minute.
