Abstract

Rubber cassava (manihot glaziovii) is a tuber which is not considered food because it contains cyanide acid (HCN) which is toxic. Rubber cassava is potential as raw material of alternative energy source of bioethanol due to its carbohydrate content about 98,47%. Rubber cassava plants as bioethanol feedstocks can gow on infertile soil and their harvest period is not dependent on the season so that the harvest can take place throughout the year. This research aimed to investigate the influence of temperature and time of acid hydrolysis on the glucose levels produced. Hydrolysis of starch was done by cid hydrolysis process using chloride acid (HCl), which would convert starch to glucose. The produced glucose was measured by using chromatogaphy method. This research used time variations (120 minutes and 180 minutes) and temperature variations (60°C, 70°C, 80°C, 90°C) in the acid hidrolysis process. The results obtained the optimum temperature and time in acid hydrolysis process are 60°C and 120 minutes with glucose level of 18,88%
