Dampak Penambahan Enzim Terhadap Nilai Fisik, Kimia, dan Biologi Kacang Koro Tanpa Kulit (Canavalia Ensiformis L.)

Abstract

Penelitian ini bertujuan menginvestigasi pengaruh pengolahan dan penambahan enzim protease dan enzim polisakarida non pati (NSP) terhadap karakteristik fisik, komposisi kimia, energi dan protein metabolis kacang koro tanpa kulit. Penelitian ini menggunakan rancangan acak lengkap dengan 4 perlakuan dan 4 ulangan. Sebanyak 20 ekor ayam digunakan dalam penelitian ini, terdiri dari 16 ekor untuk mengukur energi dan protein metabolis dan 4 ekor untuk mengukur energi endogen. Perlakuan terdiri dari P0 (kacang koro tanpa kulit), P1 (P0 + enzim protease), P2 (P0 + enzim NSP), dan P3 (P0 + enzim protease + enzim NSP). Hasil analisis menunjukkan penambahan enzim protease dan NSP pada kacang koro berpengaruh nyata (P<0,05) terhadap karakteristik fisik, komposisi kimia, dan energi metabolis. Hal ini dikarenakan enzim protease dapat memecah protein menjadi peptida sehingga lebih mudah untuk diserap oleh hewan dan enzim NSP dapat memecah polisakarida non-pati sehingga dapat meningkatkan densitas pakan. Simpulannya, penambahan enzim protease dan NSP pada kacang koro tanpa kulit dapat meningkatkan energi metabolis, menjadikannya sebagai bahan pakan sumber protein alternatif yang menjanjikan untuk ayam broiler.

The objective of this research was to investigate the effects of processing, including the addition of protease enzymes and non-starch polysaccharide (NSP) on the physical characteristics, chemical composition, metabolizable energy and protein of peeled jack bean meal. The study employed a completely randomized design with 4 treatments and 4 replications. A total of 20 animals were used in this study, including 16 for measuring metabolizable energy and protein and 4 broiler chickens to measure endogenous. The treatments consisted of P0 (peeled jack bean meal), P1 (P0 + protease enzymes), P2 (P0+ NSP enzymes), and P3 (P0+ protease enzyme + NSP enzyme). The results of the analysis showed that the addition of protease and NSP enzymes to the peeled jack bean meal had a significant (P<0.05) effect on chemical composition, physical characteristics, and metabolizable energy. This was because protease enzyme specifically broke down proteins into smaller peptides, making them more accessible for absorption by the animals and NSP enzymes broke down non-starch polysaccharides which increased the bulk density of the feed. In conclusion, the addition of protease and NSP enzymes to the peeled jack bean meal increase metabolizable energy and making it a promising alternative protein source for broiler chickens
