ABSTRACT

The purpose of this study is to learn how to make yam flour and toxicity removal process in the manufacture of starch from gadung-yam. Statistical methods used in this study is completely randomized factorial design consist of two factors. The first factor is the type of absorbent material for the removal of toxins, which consists of 3 levels ie B1 = husk ash, B2= activated charcoal, B3 = bentonite. The second factor is the concentration of absorbent material (K), which consists of 3 levels ie K1=10%, K2 = 15% and K3= 20%, Combination of treatments were 3 x 3 = 9 with 3 replications, in order to obtain 27 experimental units. The results showed that the use of absorbent material with a concentration of 20% bentonite higher cyanide concentration is 6.80 ppm compared with absorbent material husk ash and activated carbon at a concentration of 20% ie 4.68 ppm and 4.82 ppm, while the type of absorbent material yam flour was highly significant (P?0.01) on water content, crude fiber content, starch content, ash content. Concentration and absorbent material as well as the interaction of both showed no effect (P >0.05) on moisture content, ash content, crude fiber content, starch content, organoleptic color and flavor.
