Optimasi Biodegradasi Lignoselulosa oleh Kapang Pelapuk Kayu (KPK) Indigenous Paecilomyces Inflatus Pnum sebagai Alternatif Pengolahan Limbah Taman Kampus Menuju “Green Campus UM”

Abstract

The purpose of this study is to find out the influence of Paecilomyces inflatus PnUM cell count and fermentation time in decreasing lignin levels, crude protein levels, and crude fat levels of Pahitan grass from campus park waste can be processed into ruminant animal feed. This study is a laboratory experiment using the Method of Complete Randomized Design (CRD) with variations in the number of spores (8.08 x 106
; 2.02 x 107 ; and 4.04 x 107 cells) and fermentation time (7, 14, and 21 days). Stages of this research: (1) Preparation of grass waste, (2) Preparation of suspension of spores isolates of wood-decay fungi Indigenous Paecilomyces inflatus PnUM, (3) Fermentation of garden waste by Indigenous Paecilomyces inflatus PnUM, and (4) Analysis of lignin levels, crude fat levels, and crude protein levels.The test was carried out in two repetitions. The best treatment using 2.02 x 107 cells with a fermentation duration of seven days produced grass with lignin levels 14.13%±0,04, crude fat levels 2.75%, crude protein levels 11.71%±0,1. Fermentation uses Wood-decay fungi Indigenous Paecilomyces inflatus PnUM as an alternative to treatment of pahitan grass waste potentially enough to provide ruminant forage feed alternatives and support UM's Green Campus program.
