PHYSICAL QUALITY OF BISCUIT CONCENTRATE CONTAINED INDIGOFERA AND SENGON WITH DIFFERENT TYPE AND CONCENTRATION OF ADHESIVE MATERIAL
Abstrak
Physical quality of biscuit concentrate as preservative feed for livestock is affected by among are the type
and concentration of adhesive material which used for binding the ingredient of feedstuff in order to be
compact. Adhesive power of the concentrate feed or complete feed ingredients depends on the amount of
concentration of binder. This experiments was aimed to reveal the effect of type and concentration of adhesive
material on physical quality of biscuit concentrate feed contained Indigofera zollingeriana. The experiment
arranged in factorial completely randomized design with two factors. The first was the type of adhesive material
consisted of molasses, cassava powder and tapioca flour. The second factor was concentration of adhesive
consisted of three level i.e. 3, 5, and 7% from total ingredients used. Physical quality of biscuit concentrate
feed comprised organoleptic test (colour, flavor, texture, and compaction), water content, spesific gravity,
material density, impact resistance of biscuit concentrate feed was measured. The result showed that type
of adhesive material significantly (P<0,05) affected of all variables observed, meanwhile the concentration
of adhesive material used significantly (P<0.05) affected only on water content, water activity, material
density, and impact resistance of biscuit concentrate feed. The interaction was found only in water content
and impact resistance variables. In conclusion that the best type of adhesive material was cassava powder
and level of 5% was the best concentration for binding the biscuit concentrat feed. The biscuit with cassava
powder at levels of 5% was physically best quality.
