Cassava waste is solid waste from the production of tapioca which still has a relatively high starch content. As it's overflow, low rices and small manufacture scale, make some glucose syrup making research as using it as raw material. Glucose syrup is defined as aclear and viscous liquid which is the main component of glucose obtained from starch hydrolysisi. These onggok starch hidrolysis using hydrochloric acid with a temperature of 130 C and shaking speed of 50 rpm. The experimental design, consisting of 3 variables and 2 replicates. Variables consisted of sample preparation, acid concentration and hidrolysis time. Sample preparation consisted of stem blancong and percolation, the concentration used in 0.03 N, 0.05 N HCL an time of hidrolysis 20 munutes, 40 minutes and 60 minutes.
Glucose syrup produced to analyze glucose, total sugar, dextrose equivalent (DE) value, Degree of Polymerization (DP), clarity, pH, ash content and dry solids. Gluxose syrup gluxose syrup were compared with results of cassava starch hydrolysis using the method of enzymatic hydrolysis and acid-enzyme, Cassava starch hydrolysis using the optimum yield is the hudroluusis of starch, gluxose syrup with a percolation treatment sample preparation, concentration of 0.05 N HCl and the gydrolysis time of 20 minutes. These conditions produce gluxose syrup with DE value of 60.80;DP value of 1.64; clarity glucose 71.83 and 273.65 g/L
