Daftar Isi:
- Availability of starch (liquid waste rice flour) and cellulose (bulrush and bamboo) are available in substantial quantities in Indonesia. This research has a goal to produce glu cose from starch, cellulose using delignification and hydrolysis process. Hydrolysis is a process for the breakdown of cellulo se into glucose; it is a raw material which gets less attention after raw material analysis have starch, cellulose and glucose levels, have potential as glucose feedstock. The Bamboos used in the hydrolysis p rocess is those that do not contain lignin and pentosan that previously performed pretreatment and delignifica tion process. This research is to produce glucose as a feedstock for bioethanol, knowing pentosan and impurities remaining in bamboo solution. This study has the objective to produce glucose and glucose as well a s an industrial prototype as a reference in developing bioethanol industry in Indonesia. Therefore it needs to be studied in the future, what is the best process that we can use, biology process or chemic al process using NaOH, HCl, and H 2 SO 4 that can optimize glucose production. The enzyme treatment is also significant bec ause the enzyme has an optimal condition, temperature and the degree of acidity (pH) and when the enzyme is in optimal conditions, it can increase its work rate. Variable remain in hydrolysis process is weight raw material 50 to 250 grams, temperature 45 � C, and stirring speed in control 200 rpm, enzyme volume on 1 to 10 ml, time 30 until 120 minutes. The comparison obtained can be used as a basis for the design of a prototype gluco se production processes and equipment. Resulting from delignification and hydrolysis process are glucose, liquid waste rice flour on 9.98% glucose contain, bulrush on 37.9% glucose contain, and bamboo on 23.6% glucose contai n. The results from hydrolysis process is glucose, and the next treatment fermented to obtain product bioethanol. Keywords: Cellulose, Delignification, Glucose, Hydrolysis, Starch
