Abstract

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.
