Abstract
Hydrolysis is a process to breakdown cellulose into glucose. Bamboo is one of the materials that have sufficiently high cellulose content. The bamboos used in the hydrolysis process those that do not contain lignin and pentose that previously performed pretreatment and delignification process. The purpose of this research is to produce glucose as a feedstock for bioethanol, knowing pentose and impurities remaining in bamboo solution. Therefore it needs to be studied in the future, what is the best process to use, biology or chemical process using acids that can optimize glucose production. The enzyme treatment is also very important because the enzyme has an optimal condition, temperature, and pH and when the enzyme is in optimal condition, it can increase the enzyme’s work rate. Variables maintained in hydrolysis process were temperature of 45 �C, bamboo solution 500 ml, and stirring speed in control 200 rpm. The free variables were enzyme’s weights of 1, 3, 5, 7, 9 gr and hydrolysis time 30, 60, 90, 110, 130 minutes. Results from the hydrolysis process can produce glucose level of 23.6% from the bamboo’s weight. The result from hydrolysis process is glucose and the next treatment is fermentation to obtain bioethanol products. Keywords: Bamboo, Cellulose, Enzyme, Hydrolysis
