Penelitian bertujuan mengkaji pengaruh proteksi bungkil kedelai menggunakan ekstrak daun mahoni terhadap produk fermentasi rumen secara in vitro. Materi yang digunakan yaitu cairan rumen sapi, ransum basal terdiri dari konsentrat dan rumput gajah dengan rasio 60:40%, serta daun mahoni. Penelitian dilaksanakan dalam tiga tahap yaitu ekstraksi mahoni, proteksi protein menggunakan ekstrak mahoni, dan tahap in vitro. Pengujian dilakukan secara in vitro dan mengunakan rancangan acak lengkap (RAL). Perlakuan terdiri 4 macam proteksi bungkil kedelai dengan konsentrasi tanin 0% (P0); 1,5% (P1); 3% (P2); dan 4,5% (P3). Data yang diperoleh dianalisis dengan analisis variansi dan perbedaan rerata perlakuan diuji menggunakan orthogonal polinomial. Hasil penelitian menunjukan bahwa penambahan bungkil kedelai terproteksi estrak daun mahoni berpengaruh sangat nyata (P<0,01) terhadap VFA parsial (asetat, propionat, dan butirat), gas metan, protozoa, N-NH3, SPM, RUDP, dan protein terlarut. Pemberian taraf 1,5% menghasilkan produk VFA parsial yang tidak berbeda nyata dengan kontrol dan mampu meningkatkan SPM dengan efisiensi energi terbaik. Pemberian taraf 3% mendapatkan produksi VFA parsial tertinggi, namun menghasilkan produksi gas metan tertinggi pula. Pemberian taraf 4,5% menghasilkan konsentrasi VFA, SPM, dan RUDP tertinggi namun terjadi penunurunan pada protein terlarut yang menunjukan terjadinya over proteksi. Berdasarkan penelitian dapat disimpulkan bahwa taraf 1,5% menghasilkan efisiensi energi terbaik dibanding taraf lainnya, dan secara efektif mampu meningkatan RUDP dan protein terlarut tanpa mengganggu aktivitas bakteri rumen.

This study examines the protective effect soybean meal using mahogany leaf extract on in vitro rumen fermentation products. The materials used were beef rumen fluid, basal ration consisting of concentrate and elephant grass with a ratio of 60: 40%, and mahogany leaves. The study was carried out in three stages, namely mahogany extraction, protein protection using mahogany extract, and in vitro stages. The test was carried out in vitro and used a completely randomized design (CRD). The treatments consisted of 4 types of protection for soybean meal with a concentration of tannins 0% (P0); 1.5% (P1); 3% (P2); and 4.5% (P3). The study used a analyzed by analysis of variance and the mean difference in treatment was tested using orthogonal polynomials. The results showed that the addition of soybean meal protected by mahogany leaf extract had a very significant effect (P <0.01) on partial VFA (acetate, propionate, and butyrate), methane gas, protozoa, N-NH3, SPM, RUDP, and dissolved protein. Level of 1.5% resulted in a partial VFA product that was not significantly different from the control and was able to increase the SPM with the best energy efficiency. Level of 3% obtained the highest partial VFA production, but also produced the highest methane gas production. Administration of 4.5% level resulted in the highest concentrations of VFA, SPM, and RUDP but there was a decrease in dissolved protein which indicated overprotection. Based on the research, it can be concluded that the level of 1.5% produces the best energy efficiency compared to other levels, and can effectively increase RUDP and dissolved protein without disturbing the activity of rumen bacteria.
