<![CDATA[This research aims to 1) find out the effect of acid concentration and interaction of the Dextroseequivalence (DE) value hydrolysis starch, 2) to find out the type and concentration of acid that produces highest DE value starch hydrolysis results. This study used a factorial Randomized Block Design with factorial pattern. The first factor is the type of acid solvent consisting of 3 levelshydrolysis of starch with HNO33M, hydrolysis of starch with H2SO4 3M, hydrolysis of starch HCl 3M and the second factor is : 5%, 6%, 7%. Each treatment was divided into two according by the time of implementation. Variables observed that reducing sugar, total sugar, and Dextroseequivalence (DE). Determining the best treatment done with the analysis of the DE value of taro starch. Treatment acids very significant effect on the value of hydrolyzed taro starch DE while the acid concentration and interaction treatment did not significantly affect on the value of taro starch DE hydrolyzed. Starch hydrolysis involves the kinds of 3M sulfuric acid at a concentration of 7% is the best treatment to the value of Dextrose Equivalence (DE) highest, the number of 37,93%. Keywords: hydrolysis, acid, DE, starch, taro]]>
