BIOKONVERSI KULIT PISANG RAJA (Musa paradisiaca) DENGAN Rhizopus oligosphorus TERHADAP PERUBAHAN KANDUNGAN ABU, SERAT KASAR DAN LEMAK KASAR

Abstract

BIOCONVERSION OF BANANA PEEL (Musa paradisiaca)WITH Rhizopus oligosphorusTO CHANGE IN ASH CONTENT,CRUDE FIBER AND COARSE FAT.The purpose of this study was to investigate the effect of dose inoculum treatment and fermentation time on banana peel (Musa paradisiaca) to changes in ash content, crude fiber, and crude fat. This research was conducted by using banana peel waste (Musa paradisiaca) with Rhizopus oligosphorus as inoculum. The design used was RAL with 9 treatments and 3 replications. The treatments consisted of P1 (dose of inoculum 0.2% and 48 hours fermentation time), P2 (dose of inoculum 0.4% and 48 hours fermentation time), P3 (dose of inoculum 0.6% and 48 hours fermentation time), P4 (dose of inoculum 0.2% and 96 hours fermentation time), P5 (dose of inoculum 0.4% and 96 hours fermentation time), P6 (dose of inoculum 0.6% and 96 hours fermentation time), P7 (dose of inoculum 0.2% and 144 hours fermentation time), P8 (dose of inoculum 0.4% and 144 hours fermentation time) and P9 (dose of inoculum 0.6% and 144 hours fermentation time). This research has been conducted since February 12 until March 3, 2017 at the Feed Technology Laboratory of the Faculty of Animal Husbandry of Sam Ratulangi University of Manado. The variables measured in this study are changes in ash content, crude fiber and crude fat. The result of variance analysis showed that the fermented banana peel with Rhizopus oligosporus gave significant different effect (P<0,05) to the change of ash content, crude fiber and crude fat. The treatment of inoculum dose 0.4% with fermentation time 96 hours has provided an increase in ash content37.36%, provided a decrease of crude fiber content 18.38% and provided decrease of crude fat content 17.33%.Based on the results and discussion it can be concluded that bioconversion of banana peel (Musa Paradisiaca) with Rhizopus oligosporus can increase ash content, Reduce the content of crude fiber and crude fat.
