The research purposed to find out interaction between oil palm trunk concentrations and ligninase doses to increase the fiber
fractions of oil palm trunk before using as animal feeding. The oil palm trunk treated by ligninase thermostable aimed to
hydrolysis of lignin as cell wall through separation of fiber fraction such as ADF, NDF, cellulose, and hemicellulose. The design used
in this study was a Completely Randomized Design (CRD) factorial using 2 factors: (1) Factor A consisting of three levels of ligninase
enzymes A1: 250 U/kg, A2: 500 U/kg, and A3: 750 U/kg; and (2) Factor B which is the concentration of oil palm trunks B1: 40%; B2:
60% that were repeated 3 times. The results showed that there is highly significant effect of interactions (p<0.01) between levels of
ligninase enzyme (factor A) with the concentration of oil palm trunks (factor B) to ADF, NDF, cellulose, hemicellulose and lignin
contents of hydrolysis products of oil palm trunk. The optimum concentration of oil palm trunks was 60% (v/w) and 750 U/kg of
ligninase thermostable that were required to improve the fiber fractions quality to be easily digested by ruminantia animal such as
cow, sheep, buffalo and goat.
