Pengaruh Perbedaan Aras Aspergillus Niger dan Lama Peram terhadap Kecernaan Protein Kasar dan Serat Kasar Fermentasi Kelobot Jagung Amoniasi secara In Vitro

Abstract

This research aimed to examined the effect of combination treatments of the level of Aspergillus niger (A. niger) and incubation time corn husk amoniated on crude protein (CP) and crude fiber (CF) digestibility. This research used a completely randomized factorial pattern design 3 x 3, with the treatments of A. niger levels (0, 2.5 and 5 % DM) and incubation durations (0, 7 and 14 days) with 3 replications of each treatment. The parameters observed were CP and CF digestibility. Materials used in the research were corn husk, urea, A. niger mold and ruminal fluid. Procedures used in research were preparation of amoniation of corn husk used 6% of ammonia level on 60ºC temperature with 4 days incubation time, next was fermentation, then analyzed corn husk used in vitro digestibility test also analyzed CP and CF tests. The data analyzed used ANOVA and if the result was significant, continued with Duncan's multiple range test. The result showed that the interaction of A. niger level and incubation time had a significant (p<0.05) increased CP and CF digestibility. Aspergillus niger 5% level and 14 days incubation time showed the best result on CP digestibility with 63.07% and CF digestibility with 54.39%. The conclusion were combination of A. Niger level and incubation time increased CP and CF digestibility on corn husk.

Pengaruh Pengolahan Kimia Dan Biologis Pada Kelobot Jagung Terhadap Kandungan Adf Dan NDF

“…Hasil penelitian pada Tabel 1 menunjukkan bahwa perlakuan amofer mengalami penurunan kadar ADF kelobot jagung dengan rata-rata kadar ADF 41,36%. Hal ini sesuai dengan hasil penelitian Moeda et al (2017) proses fermentasi menggunakan kapang Aspergilus niger mampu memutus ikatan atau sebagian ikatan antara selulosa dan hemiselulosa dengan lignin dan silika, sehingga merombak sistem dinding sel. Kapang mampu tumbuh dan mengurai ikatan lignoselulosa dan hemiselulosa.…”
