Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh lama ensilase terhadap kualitas fraksi serat kasar silase limbah pucuk tebu (Saccharum officinarum) yang diinokulasi dengan bakteri asam laktat yang dipilih. Penelitian ini dilakukan dalam dua Tahap. Tahap pertama adalah pengayakan dan seleksi bakteri asam laktat dari pucuk tebu dan tahap kedua adalah pembuatan silase pucuk tebu dengan bakteri asam laktat hasil penelitian tahap pertama. Penelitian dilakukan di laboratorium Nutrisi dan Makanan Ternak Fakultas Pertanian Universitas Sriwijaya, Palembang. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan : P1 (lama fermentasi 7 hari), P2 (lama fermentasi 14 hari), P3 (lama fermentasi 21 hari), dan P4 (lama fermentasi 28 hari). Parameter yang diamati adalah NDF, ADF, selulosa, lignin, pHsilase dan populasi bakteri asam laktat. Hasil penelitian menunjukkan, perlakuan yang memberikan pengaruh signifikan pada NDF (P1 66.90%, P2 70.79%, P3 70.83% and P4 69.26%) dan ADF (P1 62.78%, P2 63.41%, P3 63.58% and P4 66.94%, sedangkan untuk selulosa, lignin, dan pH silase adalah non signifikan. Disimpulkan bahwa inokulasi bakteri asam laktat terseleksi dapat meningkatkan kualitas fermentasi silase pucuk tebu dan waktu ensilase dapat dipercepat dari 21 hari menjadi 7 hari. kata kunci : lama ensilase, kualitas fraksi serat kasar, inokulasi, bakteri asam laktat. AbstractThe objective of this research was to know the effect of ensilage time on fiber fraction quality of sugarcane top (Saccharum officinarum) inoculated with selected lactic acid bacteria. This research was conducted in two stage. First stage was lactic acid bacteria isolated from sugarcane top and second sugarcane top ensilage with selected lacticacid bacteria. There were held on Animal feed and Nutritive Laboratory Faculty of Agriculture, Sriwijaya University. This research used Completely Randomized Design with 4 treatments and 4 replications: P1 (7 days ensilage), P2 (14 days ensilage), P3 (21 days ensilage), P4 (28 days ensilage). Observed parameters were NDF, ADF,cellulose, lignin, pH silage and population lactic acid bacteria. The result showed that treatment gave significant effect on NDF (P1 66.90%, P2 70.79%, P3 70.83% and P4 69.26%) and ADF (P1 62.78%, P2 63.41%, P3 63.58% and P4 66.94%, however cellulose, lignin and pH silage were non significant. In conclution, selected lactic acidbacteria could improved silage fermentation quality of sugarcane top and ensilage time were improved from 21 days to 7 days. key Words: Ensilage time, fiber fraction quality, inoculant, lactic acid bactery

Abstract

Up to the present time the compost heap of sugar cane has not yet been untilized to the greatest extent. The compost heap, however, has been a major animal feed. In Indonesia about 6.49 million sugar cane tops, 2.78 million ton kletekan and 1.86 million ton sugar sogolan can be obtained each year. By product of sugar processing can yield bagasse, blotong and molasses. All of these by products are potential as a substitute for common forage in ruminants particularly during a relatively long dry season as long protein sources provided. On the other hand the supply of animal feed is becoming scarce and expensive. The farm land growth is limited, especially in dry season. With regard to the potentials mentioned along with animal feed technology, the compost heap of the sugar cane can be converted into essential animal feed. The waste of sugar cane can be processed become wafer and the use can reached 50 ? 55 % from the total of the forage in ruminants.Key words : waste, sugar can, forage, wafer, ruminants.

Abstract

Feed represent especial factors of animal husbandry because owning biggest expense from production cost. Feed effi ciency must be done to increase earnings. One of effort for the matter of that is look for alternative of raw material feed of cheaper livestock that is cassava peels. Cassava peels represent waste product from cassava industry with amount 1,998 million ton in the year 2006 in Indonesia (10 percentage of corm of yielded cassava). As constraint is its amount is which have the fl uctuation so that need depository effort of cassava peels. This research aim to know infl uence of use propionic acid as preservative to quality of nutrient of cassava peels. A period of depository observed too for its quality. Research conducted by during six-month in feed industrial laboratory of indicate that addition of 0.3% propionic acids and depository period infl uence quality of nutrient of cassava peels manifestly (P 0.05). Addition of 0.3% propionic acid gratuity not yet able to pursue growth of microorganism during depository. Growth of mould during depository infl uence to descend of water percentage, organics substance, protein, digesting of organic substance and digesting of dry substance.Key words : cassava pells, waste, propionic acids, nutrient.
