Abstract

Limbah pertanian merupakan salah satu sumberdaya yang dapat dimanfaatkan sebagai sumber pakan seperti dedak dari tanaman sorgum. Riset ini dilakukan guna mengetahui pengaruh pemanfaatan dedak sorgum dalam konsentrat   terhadap kecernaan bahan kering (KcBK), kecernaan bahan organik (KcBO), dan konsentrasi metana (CH4) secara in vitro. Riset ini memakai Rancangan Acak Lengkap (RAL) dengan 4 perlakuan serta 4 ulangan. Perlakuannya meliputi S0: konsentrat tanpa dedak sorgum, S1: konsentrat yang mengandung 25% dedak sorgum pengganti jagung, S2: konsentrat yang mengandung 50% dedak sorgum pengganti jagung, serta S3: konsentrat yang mengandung 75% dedak sorgum pengganti jagung. Nilai rerata dari kecernaan bahan kering adalah 71,29-77,71%, kecernaan bahan organik 70,61-76,61%, konsentrasi CH4 adalah 51735,81-61415,63 ml/L. Hasil penelitian menunjukkan perlakuan berpengaruh sangat nyata (P<0,01) terhadap kecernaan bahan kering dan kecernaan bahan organik, serta berpengaruh tidak nyata (P>0,05) terhadap konsentrasi CH4. Dapat disimpulkan bahwa penggunaan level dedak sorgum sampai 75% selaku pengganti jagung dalam konsentrat bisa menambah kecernaan bahan kering serta kecernaan bahan organik, tetapi konsentrasi metana yang dihasilkan relatif sama. Agricultural waste is one of the resources that can be used as a source of feed such as bran from sorghum plants. This research was conducted to determine the effect of using sorghum bran in concentrate on dry matter digestibility (KcBK), organic matter digestibility (KcBO), and methane (CH4) concentration in vitro. This research used a completely randomized design (CRD) with 4 treatments and 4 replications. The treatments included S0: concentrate without sorghum bran, S1: concentrate containing 25% sorghum bran substitute for corn, S2: concentrate containing 50% sorghum bran substitute for corn, and S3: concentrate containing 75% sorghum bran substitute for corn. The mean value of dry matter digestibility was 71.29-77.71%, organic matter digestibility was 70.61-76.61%, CH4 concentration was 51735.81-61415.63 ml/L. The results showed that the treatment had a very significant effect (P<0.01) on dry matter digestibility and organic matter digestibility, and an insignificant effect (P>0.05) on CH4 concentration. It can be concluded that the use of sorghum bran levels up to 75% as a substitute for corn in concentrate can increase dry matter digestibility and organic matter digestibility, but the concentration of methane produced is relatively the same.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh imbangan Karbon-Nitrogen dalam ensilase campuran lelehanak (Mucuna pruriensis)dan rumput kume (Sorghum Plumosum Var Timorense) terhadap kecernaan in vitro bahan kering, bahan organik dan protein kasar. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 4 ulangan.  Perlakuan tersebut yaitu C/N20 = mucuna 4591 gr + rumput kume 387 gr + dedak padi 20 gr, C/N30 = mucuna 2772 gr + rumput kume 2115 gr + dedak padi 111 gr dan C/N40 = mucuna 728 gr + rumput kume 4057 gr + dedak padi 213 gr. Data dianalisis menggunakan Analisis of Variance (ANOVA) dan dilanjutkan dengan uji jarak berganda Duncan. Hasil analisis statistik menunjukkan bahwa perlakuan berpengaruh sangat nyata (p<0,01) terhadap kecernaan bahan kering, kecernaan bahan organik dan kecernaan protein kasar.Perlakuan C/N20 nyata lebih tinggi kecernaan in vitro bahan kering dibanding perlakuan lainnya sedangkan perlakuan C/N20 dan CN30 kecernaan bahan organic dan protein kasar tidak berbeda tetapi lebih tinggi dari CN40. Disimpulkan bahwa penggunaan Imbangan C/N 20 dalam ensilase campuran lelehanak (mucuna pruriensis) dan rumput kume (sorghum plumosum var. timorense) lebih baik dalam meningkatkan Kecernaanbahan kering,  bahan organik dan protein kasar secara in vitro. The aim of this study was to determine the effect of the carbon-nitrogen balance in the ensilage of a mixture of molasses (Mucuna pruriensis) and kume grass (Sorghum Plumosum Var Timorense) on in vitro digestibility of dry matter, organic matter and crude protein.This study used a completely randomized design (CRD) with 3 treatments and 4 replications. The treatments were C/N20 = mucuna 4591 gr + kume grass 387 gr + rice bran 20 gr, C/N30 = mucuna 2772 gr + kume grass 2115 gr + rice bran 111 gr and C/N40 = mucuna 728 gr + kume grass 4057 gr + rice bran 213 gr. Data were analyzed using Analysis of Variance (ANOVA) and continued with Duncan's multiple range test. The results of statistical analysis showed that the treatment had a very significant effect (p<0.01) on dry matter digestibility, organic matter digestibility and crude protein digestibility. The C/N20 treatment significantly higher in vitro dry matter digestibility than other treatments, while in the C/N20 and CN30 treatments, the digestibility of organic matter and crude protein was not different but higher than CN40. It was concluded that the use of the C/N 20 balance in the ensilage of a mixture of lelehanak (Mucuna pruriensis) and kume grass (Sorghum plumosum var. timorense) was better in increasing the digestibility of dry matter, organic matter and crude protein in vitro.
