The Estimation of Body Weight in Aceh Cattle using some Body Dimension
No full textThis study aims to find the best estimation of body weight (BW) of Aceh cattle (three year ages) by body dimensions: hearth girth (HG), body length (BL) and width height (WH) in Aceh cattle at BPTU-HPT Sapi Aceh Indrapuri. The materials in this research were 79 adults Aceh cattle (three years old) which consisted of 40 female cattle and 39 male cattle. The results showed that the regression formula for adult male cattle were BW = 2.50 (HG) + 0.19 (BL) + 0.18 (WH) – 197.89 and for adult female cattle were BW = 1.43 (HG) + 1.51 (BL) + 0.15 (WH) – 195.42. The correlation coefficient value (r) of three body size to BW in adult male-female cattle were 0.94 and 0.86 respectively. The determination coefficient value (R2) in their formula were 0.88 (male) and 0.74 (female). The adult weight of Aceh cattle could be explain by HG, BL and WH as + 80 % (male) and + 70 % (female), and the otherwise from the unknown factor in out regression model

Isolation and Identification of Bacteria that Has Potential as Producer of Protease Enzyme in the Tannery Industry, PT. Adi Satria Abadi (ASA), Yogyakarta
Get PDFBacteria are one of the microorganisms that have the potential as a producer of protease enzyme. Tannery industrial waste is one of the media predicted to contain a number of proteolytic bacteria because of the waste generated is composed largely of protein and fat which are good as growing medium for bacteria. This study aimed to isolate and identify bacteria that have the potential as a producer of protease enzyme. Research conducted at the waste water processing installation (WWPI), tannery industry of PT.Adi Satria Abadi (ASA), Sitimulyo, Bantul, Yogyakarta and Laboratory of Animal Product and Food, Faculty of Animal Science, Gadjah Mada University, Yogyakarta. Solid waste (SW), waste water (WW) and soil (S) around the industry are used as source of isolates. Random screening methods used for isolation and identification. The results obtained by isolation and identification of 1264 colonies (621 colonies from the SW, 156 of the WW and 487 of S). Thirty one colonies (2.5%) were identified as potentially proteolytic bacteria by the presence of clear zone (halo) around the colony while the 1.233 colonies (97.5%) were not potential. The third colony isolates look like a white crust, firmly attached to the medium, round, white to resemble wool and convex. Bacterial isolates from the S and SW at pH 10 and 12 were potential as a source of proteases with Proteolytic Index (PI)≥3, while the one isolated from WW was less potential

Characteristics and Mechanism of Gelatination of Dangke Curd by Physico-chemical Properties and Microstructure
Get PDFDangke is a dairy product which is known as traditional cheese of Enrekang District, South Sulawesi. It is made by heated clotting of buffalo, cow, goat or sheep milk with addition of papaya sap (Carica papaya) or pineapple juice. Dangke has been well known by South Sulawesi community but information is very limited regarding to its characteristics with standardized quality. The objective of this study was to produce dangke with standardized quality (physical properties, chemical properties and microstructure) so that, at the end, this product can become a certified product having specific characteristics, which is in turn can be introduced nationally or internationally as a genuine product of South Sulawesi. It is expected that this Indonesian cheese will be increasingly popular as Cheddar (England); Gouda and Edan (Netherland); Emmental and Gruyere (Swiss); Limburger, Cammembert and Brie (France); Gorgonzola, Mozzarella, and Romano (Italy); Brunost (Norway); Damiati (Egypt) and so on. Dangke was prepared using 18 L of raw whole milk and heated at 75, 80, 85, 90, 95 and 100oC for 1 minute and coagulated by addition of papaya sap 0.3%, 0.4% and 0.5%, and added 1% of salt. Curd was poured to Dangke cheese template and pressed until compact. The cheese was packaged riped at approximately 5oC. Dangke was evaluated towards physical properties (hardness, pH, elasticity), chemical properties (percentages of fat, protein, and lactic acid) and microstructure. Hardness and elasticity determined by rheometer, pH values measured by using a Hanna-pH-meter. Microstructure was viewed by a fasecontrast and light microscope in 1000 x of magnification. Level of fat and protein were analyzed by proximate analysis. Percentage of lactic acid was evaluated by titratable acidity. Result of this study showed that higher heating temperature decreased protein and fat contents, as well as lactose but increased pH and lactic acid. The best structure and the highest protein content of dangke was obtained by heating temperature of 75oC with 0.5% papaya sap
The Role of Marketing Agencies in Eggs Selling at Layer Farmers in Indonesia: A Case Study in West Java, Bali and South Sulawesi
Get PDFThe aim of this study was to determine the role of some marketing agencies in selling eggs of layer farmers in Indonesia. The research was conducted in West Java, Bali and South Sulawesi. The selection of those regions was based on the category that they had the most populous layer farmers compared to other regions. The number of respondents was determined using quota sampling method from FAO poultry industry data, i.e. 60 layer farmers of West Java and South Sulawesi respectively, and 41 farmers of Bali. The farmers involved in the study were those having layer population between 2000-5000 hens. Data were collected from the respondents through deep interview using a questioner that have been prepared before hand and conducted in May 2010. The results of the study indicated that among the marketing agencies studied in the three regions; West Java, Bali and South Sulawesi, the role of whole sellers in eggs selling of layer farmers was the most important one, followed by restaurants, traditional markets, consumers and the poultry shop, respectively. In terms of egg selling price in the three regions, the most expensive was in Bali and the cheapest one was in South Sulawesi
The effect of nitrogen fertilization and water stress on stomatal aperture, chlorophyll content and proline accumulation of Napier grass (Pennisetum purpureum Schum)
Get PDFThe objective of the study was to determine the effect of nitrogen fertilization and water stress on the stomatal aperture, chlorophyll and proline accumulation of Napier grass (Pennisetum purpureum Schum.) The effect of water stress and nitrogen fertilizer levels were evaluated within an arrangement of Completely Randomized Design with factorial pattern (2x3). The variables observed were stomatal aperture, total chlorophyll and proline content. The results showed interaction between water stress and the level of fertilization. Interaction between water stress with nitrogen fertilization showed that the stomatal openings were more narrow (P<0.05) in water stressed plants compared to plants with excess water and that decreased stomatal aperture was not significant (P>0.05) with increasing levels of nitrogen fertilization either with sufficient water or with water stress. The exception is treatment of enough water and fertilizer 250 kg N/ha (P<0.05) where stomatal aperture decreased compared with no fertilizer. The total chlorophyll content of both the sufficiently watered and the water stressed Napier grass on nitrogen fertilizer rose with increasing doses of nitrogen fertilizer. The conditioning of water stress with fertilizer dose of 0 kg N/ha and 150 kg N/ha did not increase the total chlorophyll, however a dose of 250 kg N/ha resulted in an increase of total chlorophyll (P<0.05). Interaction between water stress and nitrogen fertilizer levels showed that the content of proline rose (P<0.05) with increasing levels of nitrogen fertilization, as well as with water stress treatment (P<0.05). It is concluded that water stress on Napier grass plants lowers stomatal aperture width, but increases proline accumulation and nitrogen fertilizer increases total chlorophyll and proline accumulation. There was an interaction between nitrogen fertilizer with water stress
