Abstract Cassava pulp, which is comprised of mostly carbohydrate (66%) and fiber (15%), was used as raw material in glucose production. The hydrolysis of cassava pulp was accomplished by using acids or enzymes. The hydrolyzation of cassava by hydrochloric acid produced hydrolyzate with a reducing sugar content of 61.68 + 0.62 % in 2.5 hours. This paper aimed to increase the hydrolyzation of cassava pulp by using enzymes, mixed enzymes and sequences in combination with ultra-filtration to enhance the efficiency of the process. It was found that the combination of 285.6 MWU of alpha-amylase and 0.21 DU of glucoamylase per gram of cassava pulp with a pH of 5.0 at a temperature of 50oC gave a hydrolyzate with higher reducing sugar content than using either enzyme alone. The hydrolyzation rate was 0.133 mg of reducing sugar per minute. Reducing sugar was produced at the rate of 24.1 g/100g of cassava pulp when hydrolyzed for 4 hrs. The application of the ultrafiltration system with an average pressure of 98 kPa, a flow rate passed the membrane surface of 130 ml/sec and a filter area of 28.27 cm2 gave a yield of 29 g reducing sugar /100 g cassava pulp, which was
