Komponen Serat Sabut Kelapa yang Difermentasi Menggunakan Mikroba Pencerna Serat dari Rumen Kerbau

Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengkaji pengaruh perbedaan lama pemeraman dan aras starter mikroba pencerna serat dari rumen kerbau terhadap komponen serat dan perubahan struktur jaringan sabut kelapa fermentasi. Percobaan menggunakan rancangan acak lengkap pola faktorial 3x3 dan 4 ulangan. Fermentasi sabut kelapa menggunakan mikroba pencerna serat dari rumen kerbau sebagai starter dengan perlakuan aras starter (0, 2,5 dan 5%) dan lama peram (0, 7 dan 14 hari). Parameter yang diamati adalah komponen serat dan perubahan struktur jaringan. Data dianalisis menggunakan analisis ragam, dilanjutkan uji jarak berganda Duncan. Hasil penelitian menunjukkan tidak terdapat pengaruh interaksi (P>0,05) antara perbedaan aras starter dan lama peram terhadap kadar neutral detergent fiber (NDF), acid detergent fiber (ADF), hemiselulosa, selulosa dan lignin. Kesimpulan penelitian ini adalah penurunan kadar komponen serat serta peningkatan kerusakan jaringan seiring dengan peningkatan aras starter dan lama pemeraman. Hal ini disebabkan oleh penurunan kadar selulosa dan lignin sedangkan kadar hemiselulosa tidak dipengaruhi. Hal ini didukung oleh pengamatan terhadap perubahan struktur jaringan. 

(Fiber components of fermented coconut husk using fibre degrading microbes from buffalo rumen) 

ABSTRACT. This study aimed to examine the effect of different fermentation periods and levels of fiber-degrading microbial starter from buffalo rumen fluid on fiber component and tissue structure alteration of coconut husk. The experimental design used was factorial randomized complete 3x3 and 4 replications. The coconut husk fermentation was using fiber-degrading microbial obtained from buffalo rumen fluid as a starter with different treatments of starter levels (0, 2.5 and 5%) and fermentation periods (0, 7 and 14 days). Parameters observed were fiber component and tissue structure alteration. The data were analyzed by analysis of variance and continued by Duncan’s Multiple Range Test. The results of this research showed that there was no interaction effect (P>0.05) between starter level and fermentation period on NDF, ADF, hemicellulose, cellulose and lignin contents. The conclusion of this research was decreased fiber component content and damage to tissue structure of coconut husk along with increased starter level and fermentation period. This is caused by decreased levels of cellulose and lignin while hemicellulose levels were not affected. This is supported by observations of changes in tissue structure alteration.
