Penelitian ini bertujuan untuk mengkaji pengaruh penggunaan silase limbah daun nanas sebagai pengganti rumput gajah berdasarkan kadar Nitrogen-amonia (N-NH3) dan Konsentrasi Volatile Fatty Acid (VFA) total cairan rumen sapi potong secara in vitro. Penelitian dilaksanakan pada tanggal 25 Agustus sampai 20 September 2021 di Laboratorium Ilmu Nutrisi dan Makanan Ternak Fakultas Peternakan Universitas Jenderal Soedirman, Purwokerto. Penelitian menggunakan metode in vitro dengan rancangan acak lengkap, 5 perlakuan dan setiap perlakuan diulang sebanyak 4 kali sehingga terdapat 20 unit percobaan. Perlakuan yang diuji terdiri dari P0 (60% konsentrat + 40% rumput gajah), P1 (60% konsentrat + 30% rumput gajah + 10% silase daun nanas), P2 (60% konsentrat + 20% rumput gajah + 20% silase daun nanas), P3 (60% konsentrat + 10% rumput gajah + 30% silase daun nanas), serta P4 (60% konsentrat + 40% silase daun nanas). Hasil penelitian menunjukkan bahwa perlakuan berpengaruh tidak nyata (P>0,05) terhadap kadar N-NH3 dan konsentrasi VFA. Disimpulkan bahwa penggunaan silase daun nanas pada imbangan 40% rumput gajah dan 60% konsentrat dapat menggantikan rumput gajah dalam pakan sapi potong sampai 100% berdasarkan pengukuran kadar N-NH3 dan konsentrasi VFA total secara in vitro.

This study aims to examine the effect of using pineapple leaf waste silage as a substitute for elephant grass based on levels of Nitrogen-ammonia (N-NH3) and Volatile Fatty Acid (VFA) concentration in total rumen fluid of beef cattle in vitro. The research was conducted from August 25 to September 20, 2021 at the Laboratory of Nutrition and Animal Feed Science, Faculty of Animal Science, Jenderal Sudirman University, Purwokerto. The study using an in vitro method with a completely randomized design, 5 treatments and each treatment was repeated 4 times so that there were 20 research units. The treatments used consisted of P0 (60% concentrate + 40% elephant grass), P1 (60% concentrate + 30% elephant grass + 10% pineapple leaf silage), P2 (60% concentrate + 20% elephant grass + 20% pineapple leaf silage), P3 (60% concentrate + 10% elephant grass + 30% pineapple leaf silage), and P4 (60% concentrate and 40% pineapple leaf silage). The results showed that the treatment had no significant effect (P>0.05) on the levels of N-NH3 and the concentration of VFA. It was concluded that the use of pineapple leaf silage at a balance of 40% elephant grass and 60% concentrate could replace elephant grass in beef cattle feed up to 100% based on in vitro measurements of N-NH3 levels and total VFA concentrations.
