Effect of probiotic duration and dose of coffee peel fermentation (Coffea sp.) on crude protein and crude fiber as an alternative fish feed ingredient

Abstract

The research aimed to find out whether there was interaction between fermentation duration and probiotics dose toward the increase in crude protein and decrease in crude fiber content in coffee peel. This research was experimental using complete randomized design (RAL) factorial, data analysis using duncan. The result of the research showed that there was interaction between duration and probiotics doses in coffee peel fermentation to crude protein in day 5 of fermentation duration with probiotics dose of 5%, it was the highest result of crude protein content. There was no interaction between duration fermentation and probiotics dose in fermentation of coffee peel toward crude fiber content in day 7 duration of fermentation with probiotics dose of 5%, it was the result of the lowest crude fiber. Fermentation in 7 days with dose of 5% was the best result. There was increase of protein from 12.15% to 13.93% and decrease of fiber from 34.27% to 30.8%.

The Effect of Feed Protein Levels on The Growth of Kissing Gourami (Helostoma temminckii)

“…According to Mukti (2012), high crude fiber causes a more significant portion of excreta, so the absorption of digestible protein decreases. In general, fish require a maximum of 8-12% crude fiber (Fatmawati et al, 2020). The crude fiber level in this study was still within the range of fish needs in general.…”

Peningkatan Kualitas Kulit Kopi dengan Metode Fermentasi untuk Budidaya Ikan (Review)

“…Di tahun yang sama, Fatmawati et al (2020), melaporkan hasil penelitian menggunakan tepung kulit kopi yang telah difermentasikan dengan dosis probiotik 0, 1, 3, 5 % dengan menggunakan waktu fermentasi 5 dan 7 hari. Mereka ingin melihat interaksi antara lama fermentasi dan dosis probiotik terhadap peningkatan protein kasar dan penurunan kandungan serat kasar.…”
