KADAR NDF DAN ADF LIMBAH AMPAS TEBU DIFERMENTASI DENGAN ARAS RAGI ISI RUMEN YANG BERBEDA

Abstract

Bagasse (bagasse) is a sugar factory solid waste that has not been utilized optimally. Through the fermentation process using Rumen Contents Yeast (RIR), it is expected to improve the quality and digestibility level. Rumen contents yeast  is the rumen contents of fresh cattle that are added with RAC (Readly Available Carbohydrat) in the form of corn as a source of energy fermenters in fermentation. The study aims to determine the level of addition of rumen contents yeast to reduce  levels of NDF and ADF in bagasse pulp fermentation. In this study used a completely randomized design (CRD). There were 5 treatments namely : P₀ = Bagasse + 0% RIR, P₁ = Bagasse + 5% RIR, P₂ = Bagasse + 10% RIR, P₃ = Bagasse + 15% RIR, P₄ = Bagasse + 20% RIR and 4 replications. The material used was 400 gr of bagasse which was chopped, mixed with yeast of rumen contents and homogenized by stirring. Put in a biodogester using a jar. The fermentation process lasts for 21 days anaerobically.The variables observed were NDF and ADF. The conclusion from the results of this study was obtained that the value of NDF and ADF  ​​in the treatment of bagasse which are fermented with different levels of rumen content  can reduce NDF levels of 71.51% and ADF levels of 44.78%. The highest NDF levels were found at P0, which was 76.01% while the lowest levels were found in P4, which was 68.07%. For the highest ADF levels, it is at P0, which is 50.81 and is lowest at P4, which is 41.61%. This is because the content of the postulated microbes can produce certain enzymes to degrade the content of lignocellulose and cellulose contained in sugarcane bagasse in the form of crystals.
