Abstract

This research aims to 1)  find out the effect of acid concentration and  interaction of the  Dextrose
equivalence  (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  levels
hydrolysis of starch with HNO
3
3M, 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  Dextrose
equivalence (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%.
