| Abstract | Cassava ( Manihot esculenta) leaf was treated with enzymes
namely, cellulase, pectinase, papain and bromelain. Only cellulase
was succeed in cassava leaves treatment in term of degradation
cellulose in cassava leaves to glucose by Glucostat as the method
of glucose determination . Other enzymes such pectinase, papain and
bromelain showed no reaction with cassava leaves as substrate. The
optimum conditions of cellulase enzyme are pH 4.8 and temperature
50°C . The optimum of cassava leaves concentration for cellulase
reaction is 25.0% (w/v) and the optimum cellulase concentration is
1 . 0% (w/w). The reaction time was indicated when the reaction was
taken placed in 10 liter reactor which pointed 6 hours for the
reaction time. Treated cassava leaves was recovered by oven dry at
70"C for 24 hours which provided 10.86% in fiber content (lower
than untreated sundried cassava leaves) and higher in ash content
i.e . 12.00%. Daily Weight Gain (DWG) of fish fed by treated cassava leaves (cellulase treatment) was 0 . 68 which was not significant higher than untreated cassavs leaves . For feed utilization of fish fed by treated cassava leaves there were 59.53% in Apparent Prate in Digestibility ( APD) , 5 8. 60% in Total Digestibility (TD), 15.26% in Apparent Net Pratein Utilization ( ANPU) and 1. 0% . in Protein Eff iceincy Ratio (PER) which were comparable to untrated cassava leaves. |
