KUALITAS NUTRISI AMPAS SAGU HASIL FERMENTASI JAMUR TIRAM PUTIH (Pleurotus ostreatus) DENGAN WAKTU PANEN YANG BERBEDA

Abstract

Improving local feedstuff which is abundantly available in Maluku Province suh as sago (Metroxylon rumphii) by-product to be a nutritional feedstuff for live is an innovative way to address the scarcity of nutritious feed for livestock in Maluku. The purpose of this research was arranged into a complete randomized design with four treatments: control (no fermentation), before harvest (after full mycelium), the first harvest, and the second harvest. Each treatment was replicated triple. Least square test was applied to determine the statistical differences among the treatmenst. The observed variables were dry matter, crude protein, Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF) and lignin. The result showed that there were significant differences (P<0.05) on dry matter content, protein content, NDF, ADF and lignin content among treatments. Average dry matter content in each treatment was 40.08%, 35.16%, 28,78% and 27,23% for control, before harvest, the second harvest and the first harvest, respectively. Avarage protein content in each treatment was 5.52%, 5.33%, 5.21% and 2.05% for before harvest, the first harvest, the second harvest and control, respectively. Avarage NDF content in each treatment was 55.59%, 51.21%, 48.73% and 46.43% for control, before harvest, the first harvest and the second harvest, respectively. Average ADF content in each treatment was 46.53%, 44.57%, 43.74% and 42.13% for control, before harvest, the secobd harvest and the first harvest, respectively. Average lignin content in each treatment was 5.63%,4.37%, 3.29% and 3.21% for control, before harvest, the second harvest and the first harvesst, respectively. Based on nutrient content, it is suggested that fermented sago by-product on the first harvest time can be applied as livestock feedstuff. However, fermented sago by-product on the second harvest time is economical.

“…The study conducted by [27] found that the lignin content in tofu dregs was relatively the same, IOP Publishing doi:10.1088/1755-1315/1286/1/012021 7 namely 5,17% (0 day incubation) and 5,13% (70-80 day incubation) using Pleorotus ostreatus.…”

EFEK LAMA BIOKONVERSI OLEH JAMUR TIRAM PUTIH (Pleurotus ostreatus) TERHADAP KOMPONEN SERAT SABUT KELAPA TUA (The effect of bioconversion by the white oyster mushroom (Pleurotus ostreatus) to the fibrous component of old coconut fiber)

“…Degradasi ADF ada hubungannya dengan kandungan NDF dan degradasi terhadap hemiselulosa, karena ADF merupakan selisih dari NDF dan hemiselulosa. Pluerotus oestreatus mampu merombak ikatan lignoselulosa yang merupakan komponen ADF seperti yang dilaporkan Jafari et al, (2007), dan Sangadji et al (2008) bahwa semakin lama fermentasi maka semakin berkurang 48,66% (lama inkubasi 0 hari), 40,01% (lama inkubasi 70-80 hari) kadar ADF pada ampas sagu yang difermentasi dengan P. oestreatus. Hasil penelitian ini selaras dengan penelitian Manu et al (2015) yang juga mendapatkan hasil yang sama di mana kandungan komponen serat limbah kelapa muda akibat fermentasi dengan Pleurotus ostreatus yang semakin menurun dengan meningkatnya lama inkubasi.…”

“…Hasil penelitian Sangadji et al (2008) juga melaporkan bahwa kadar lignin ampas sagu relatif sama yaitu 5,17% (lama inkubasi 0 hari) dan 5,13% (lama inkubasi 70-80 hari) yang difermentasi dengan P. oestreatus. Hasil tersebut mengindikasikan bahwa lama fermentasi telah memberikan pengaruh yang relatif sama terhadap perombakan komponen sel utama terutama lignin.…”

“…Hasil penelitian Sangadji et al (2008) melaporkan bahwa semakin lama fermentasi maka semakin kadar selulosa berkurang (36,32% pada lama inkubasi 0 hari) menjadi 18,95% pada lama inkubasi 70-80 hari) pada ampas sagu yang difermentasi dengan P. oestreatus. Sama seperti yang dilaporkan Hadrawi (2014) bahwa lama inkubasi memberi pengaruh yang sangat nyata terhadap kadar selulosa substrat serbuk gergaji, yang mrndapatkan kadar selulosa terendah pada lama inkubasi 4 bulan dan lama inkubasi 2 bulan belum berbeda nyata dengan lama inkubasi 1 bulan.…”

“…Utilization of repu is still very limited and sometimes discarded so that it can become waste that causes environmental pollution. The repu content component of the proximate analysis results has a crude protein content of 2.1%; fat 1.8%; crude fiber 20.3%; gray 4.6%; cellulose 36.3%; hemicellulose 14.6%; lignin 9.7%; and 3.3% silica [3].…”
