Abstract

ABSTRAKKualitas fisik silase akan menentukan kuantitas konsumsi ransum pada sapi potong. Penelitian ini bertujuan untuk mengetahui kualitas fisik silase pakan berbahan dasar rumput gajah. Penelitian ini dilaksanakan pada bulan Februari sampai Maret 2017 di Laboratorium Lapangan Kandang Percobaan Program Studi Peternakan dan Laboratorim Nutrisi dan Makanan Ternak Program Studi Peternakan Fakultas Pertanian Universitas Sriwijaya. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dan 5 ulangan. Perlakuan terdiri dari P0: 50% daun rumput gajah + 50% batang rumput gajah, P1: 100% daun rumput gajah + EM-4, P2: 100% batang rumput gajah + EM-4, dan P3: (50% daun rumput gajah + 50% batang rumput gajah) + EM-4. Parameter yang diamati dalam penelitian ini meliputi aroma, warna, tekstur dan pH. Hasil penelitian menunjukkan bahwa proporsi bagian tanaman tidak berpengaruh (P>0,05) terhadap karakteristik warna dan tekstur silase rumput gajah (Pennisetum Purpureum), namun berpengaruh terhadap karakteristik aroma dan nilai pH pada taraf (P<0,05). Proporsi bagian tanaman mempengaruhi kualitas fisik silase tanaman bagian daun dibandingkan bagian batang.

Abstract

The isolated and characteristiclactic acid bacteriain broilers intestineABSTRACT. The objective of the research was to evaluate and characterize of a Lactic Acid Bacteria isolated frombroilers small intestine. The research was done by three steps : (1) Isolated Lactic Acid Bacteria, (2) Gram colourize and microscopic observation and (3) Inhibitory test with pathogen bacteria. The isolation of lactic acid bacteria was proceed by clone from broilers small intestine with MRS Broth for 24 hours, thinned until 10 9with serial number, invested in MRS jell, purify by streak plate method and storage the lactic acid bacteria in an MRS angle jell. Gram colourize was done with crystal violet liquid, Iodium, Alkohol 95% and Safranin, and also microscopic observation was done by electron microscope with 40 zooming. Inhibitory test with pathogen bacteria was evaluated with Escherichia coli as testing bacteria in 2, 4, 6, 8, 10, 12, 24 dan 48 hours incubation period.The isolation result showed two sample of isolate (A1 dan A2) and consist of the observation in shape as well as colour of the bacteria growth, for sample of isolate A1 the colonies had coccus and white colour. The isolate of A2 had sarcinar. After that, gram colouring was done and microscopic observation were identified into gram-negative bacteria became bacill and bacill cocco. Inhibitory test with pathogen bacteria showed that it produced antimicrobial with 11 mm clearing zone diameter. The result of the research got Lactobacillus sp as the genera of Lactic Acid Bacteria.
