Quality Improvement of Oil Palm Waste-Based Feed Product Through Indigenous Microbial Fermentation to Reach Sustainable Agriculture

Abstract

This study aims to improve the quality of oil palm waste-based feed product through indigenous microbial fermentation. The methods used Factorial Completely Randomized Design (CRD) with a pattern of  3 x 4 with 3 replications. Treatment of factor I was the substrat combination of oil palm waste and factor II the inoculum combination of microbial. Parameters which is observed such as: dry matter, crude protein, and crude fiber.  The result showed that the uses of inoculums of indigenous microbial (Bacillus YL.B1, Trichordema YL.F8, Yeast YL.YS3) fermentation on oil palm created a significant improvement (P<0.01) by increasing crude protein content and decreasing crude fiber content. It caused the crude protein content up to 57.65% and crude fiber content down to 15,60%. This study proved that the uses of indigenous microbial fermentation improved the quality of oil palm-based waste feed product to reach sustainable agriculture.
