ABSTRAKKualitas rumput tembaga merupakan hijauan dengan produksi melimpah tetapi belum banyak dimanfaatkan secara optimal sebagai pakan ternak. Oleh karena itu, perlu dikombinasi dengan daun singkong, lumpur sawit dan disuplementasi ragi Sc untuk meningkatkan nutrisi dari ransum yang berbahan dasar rumput kumpai tembaga. Penelitian ini menggunakan metode rancangan acak lengkap (RAL) dengan 4 perlakuan dan 4 ulangan. Perlakuan terdiri dari P0= 85% rumput kumpai tembaga + 15% konsenterat, P1= 55% rumput kumpai tembaga + 30% daun singkong+15% konsenterat + 0,05% (Saccharomycas Cerevisiae), P2= 55% rumput kumpai tembaga+30% lumpur sawit+15% konsenterat+0,05% (Saccharomycas Cerevisiae), P3= 55% rumput kumpai tembaga+15% lumpur sawit+15% daun singkong+15% konsenterat + 0,05 % (Saccharomycas Cerevisiae). Parameter yang diamati adalah konsentrasi SCFA (mM), Gas Metana (ppm), dan laju produksi Gas (mL/Jam) secara in vitro. Hasil penelitian menunjukkan bahwa ransum rumput kumpai tembaga dikombinasi daun singkong, lumpur sawit dan disuplementasi ragi Sc menghasilkan Konsentrasi SCFA, Gas metana, dan Produksi Gas yang berbeda nyata (P<0,05) secara in vitro. Berdasarkan hasil penelitian dapat disimpulkan bahwa perlakuan R2 (30% lumpur sawit dan 0,05% ragi) mampu mencukupi sumber energi utama ternak dengan konsentrasi SCFA yaitu 115,25 mM, dan memiliki nilai konsentrasi gas metana yang lebih rendah yaitu 537,97 ppm, serta dapat meningkatkan nilai laju produksi gas yaitu 1.44 mL/Jam.

ABSTRACTQuality grass (Hymenachne Acutigluma) is a forage that abundant production but has not been optimally utilized as animal feed. Therefore, it needs to be combined Cassava Leaves, Palm Oil and yeast Sc Suplementation to improve the nutrients of the copper based grass ration. This study aims to determine the concentration of SCFA and in vitro gas production of grass based grass ration based on cassava leaves, palm oil and Yeast Sc supplementation. This study used a complate random design method (CRD) that 4 treatments and 4 replications. The treatment consisted of P0 = 85% (Hymenachne Acutigluma) + 15% consentate, P1 = 55% (Hymenachne Acutigluma) + 30% cassava leaves + 15% consentate + 0.05% (Saccharomycas Cerevisiae), P2 = 55% (Hymenachne Acutigluma) + 30% palm oil + 15% consentate + 0.05% (Saccharomycas Cerevisiae), P3 = 55% of copper grass + 15% palm oil + 15% cassava leaves + 15% consentate + 0,05% (Saccharomycas Cerevisiae). Parameters observed were SCFA concentration (mM), Methane Gas (ppm), and Gas production (mL / Hour) in vitro. The results showed that raccoon grass (Hymenachne Acutigluma) combined cassava leaves, palm oil and yeast Sc suplementation resulted in a significantly different concentration of SCFA, methane gas and gas production (P <0.05) in vitro. Based on research result, it can be concluded that R2 treatment (30% palm oil and 0.05% yeast Sc) is able to supply primary energy source of livestock with SCFA concentration of 115,25 mM, and have lower methane gas concentration value that is 537,97 ppm, and can increase the gas production rate of 1.44 mL / hour Keywords: Combination, Gas Production, Hymenachne Acutigluma, Methane, SCFA.
