      Abstract
      Penelitian ini bertujuan mengevaluasi penggunaan dedak padi dan ampas sagu aren (Arenga pinnata) yang difermentasi dengan jamur tiram putih (Pleurotus ostreatus) sebagai substitusi dedak padi pada konsentrat yang dikombinasikan dengan ampas tahu dan hijauan terhadap populasi mikroba rumen, karakteristik fermentasi rumen dan sintesis protein mikroba secara in vitro. Penelitian menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan. Perlakuan tersebut adalah DASAF0 = ampas tahu 52% hijauan 18% + konsentrat (30% dedak padi + 0% dedak padi dan ampas sagu aren fermentasi), DASAF5 = ampas tahu 52% hijauan 18% + 25% dedak padi + konsentrat (5% dedak padi dan ampas sagu aren fermentasi), DASAF10 = ampas tahu 52% hijauan 18% + konsentrat (20% dedak padi + 10% dedak padi dan ampas sagu aren fermentasi), DASAF15 = ampas tahu 52% hijauan 18% + konsentrat (15% dedak padi + 15% dedak padi dan ampas sagu aren fermentasi). Peubah yang diuji meliputi populasi mikroba, VFA Parsial, gas metana, dan sintesis protein mikroba. Data dianalisis dengan ANOVA dan perlakuan yang berbeda nyata akan diuji lanjut dengan Uji Duncan menggunakan software SPSS 27. Hasil penelitian menunjukkan substitusi dedak padi dengan 10% dedak padi dan ampas sagu aren fermentasi dalam konsentrat berpengaruh nyata (p<0,05) meningkatkan sintesis protein mikroba, tetapi tidak berpengaruh nyata (p>0,05) terhadap populasi mikroba, VFA parsial, dan gas metana.
       
      This study aims to evaluate the use of rice bran and sago waste (Arenga pinnata) fermented with white oyster mushrooms (Pleurotus ostreatus) as a substitute for rice bran in concentrate combined with tofu waste and green fodder on rumen microbial population, partial VFA, rumen fermentation characteristics and microbial protein synthesis in vitro. The research used a Completely Randomized Design with 4 treatments and 4 replications. The treatments were DASAF0 = tofu dregs 52% + forage 18% + concentrate (30% rice bran + 0% fermented rice bran and aren sago waste) ; DASAF5 = tofu waste 52% + forage 18% + concentrate (25% rice bran + 5% fermented rice bran and aren sago waste); DASAF10 = tofu waste 52% + forage 18% + concentrate (20% rice bran + 10% fermented rice bran and aren sago waste); DASAF15 = tofu waste 52% + forage 18% + concentrate (15% rice bran + 15% fermented rice bran and aren sago waste). The parameters tested included total microba populations, partial VFA levels, methane gas, and microbial protein synthesis. Data were analyzed using the ANOVA method, and significantly different treatments were further tested using the Duncan Test using SPSS 27 software. The results of the study showed that substitution of rice bran with 10% rice bran and fermented sago palm dregs in the concentrate had a significant effect (p<0.05) on increasing microbial protein synthesis, but had no significant effect (p>0.05) on the microbial population, partial VFA, and methane gas
