The combination of materials from dangke whey and casein can form an edible flm. The addition of a plasticizer such as glycerol, sorbitol and polyethylene glycol (PEG), in the manufacture of the edible flm can improve the characteristics of the edible flm becoming elastic, fexible and not easily fragile. The purpose of this research was to study the effect of plasticizer glycerol, sorbitol and polyethylene glycol (PEG) to the edible flm characteristics such as thickness, yield, and color (* L, * a and * b). This study was run according to completely randomized design with plasticizer types as the treatment consisted of glycerol, sorbitol, and polyethylene glycol (PEG) with a concentration of 35%. Each treatment was repeated 5 times. The results obtained indicated that the type of plasticizer did not affect the thickness of the edible flm. The yield of edible flm was 26.45 ± 0.34%, 24.53 ± 0.29%, and 22.56 ± 0.30% for glycerol, PEG, and sorbitol, respectively. The color value (*L) of edible flm was 88.40 ± 0.33 for sorbitol, 87.28 ± 0.25 for PEG, and 88.40 ± 0.33 for glycerol. The color value (*a) was 5.97 ± 0.10, 3.86 ± 0.13, and 0.09 ± 0.02, for glycerol, PEG, and sorbitol, respectively. While the color value (*b) of edible flm was 4.36 ± 0.10 for PEG, 1.32 ± 0.36 for sorbitol, and 1.10 ± 0.13 for glycerol. It was concluded that the use of sorbitol would increase brightness (*L) and the yield of edible flm. The use of glycerol has an efect on the reddish color of the edible flm (*a), while the PEG increase the yellowish color of the edible flm (*b).

Bacteria 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.

DRY MATTER PRODUCTION, CARBOHYDRATE RESERVE CONTENT AND NITROGEN UTILIZATION IN SOME TROPICAL GRASSES AS INFLUENCED BY NITROGEN FERTILIZATION AND AGE OF PLANTS . Rusdy
Jurnal Ilmu dan Teknologi Peternakan Vol. 1 No. 1 (2010)
Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

An experiment was conducted at Kyushu University Experimental Field Japan, to evaluate the effect of nitrogen fertilization and cutting age on dry mater yield, reserve carbohydrate content and nitrogen utilization in alang-alang, bahia grass and guinea grass. The grasses species were fertilized with 0. 7 and 1.5 g N/pot and cut at 50 and 70 days after nitrogen fertilization. Results of the experiment showed that as nitrogen rates increased, dry matter yield, foliage (stubble + underground parts) ratio, nitrogen concentration and nitrogen uptake of the three species increased. Alang-alang allocated a greater proportion of dry matter to stubble and underground plant parts than to foliage compared to those of bahia grass and guinea grass. Nitrogen fertilization had no consistent effect on reserve carbohydrate content, apparent nitrogen recovery and nitrogen use efficiency. Cutting at 70 days increased dry matter yield and nitrogen uptake but reduced nitrogen concentration of the three grass species. As plant grew older, foliage (stubble + underground parts) ratio decreased in alang-alang but in bahia grass and guinea grass it increased. Alang-alang was less responsive to applied nitrogen in term of nitrogen uptake compared with those of bahia grass and guinea grass, however as the plants grew older, guinea grass showed the highest nitrogen use efficiency compared with those of alang-alang and bahia grass.

SEASONAL CHANGE OF BAHIAGRASS TILLER UNDER DIFFERENT NITROGEN FERTILIZER RATE AND CUTTING HEIGHT W. Pakiding

Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

Seasonal change of bahiagrass tiller under different nitrogen fertilizer rate and cutting height was investigated over a 4-year period. Tiller dynamics were examined using a tagging technique, with treatments of two nitrogen rates [5 g N/m2 /year (LN) and 20 g N/m2/year (HN)] x three cutting heights above ground level [20 mm (LH), 120 mm (MH) and 220 mm (HH)]. Total tiller density in the first one or two years increased in LH treatments, whereas that in MH and HH treatments decreased. Thereafter, the density reached annually constant values, showing seasonal fluctuations consisting of the spring increase and the subsequent decrease. The decrease in cutting height usually increased TAR, and the increase in nitrogen rate often increased TAR in the LH treatments. TDR increased from spring to summer and decreased thereafter. In summer and autumn, HN/LH treatment often showed higher TDR than the other treatments. The balance in LH treatments increased with increasing nitrogen rate. In the other months, the balance was usually close to zero or negative, except for LH treatments in the first year. The half-life of tillers tended to increase with decreasing nitrogen rate and cutting height. Tillers appearing in autumn survived longest, and those appearing in spring shortest. The results show that bahiagrass copes with severe management conditions by increasing its tiller longevity. This is taken as an important mechanism for the high persistence of the grass. In addition, bahiagrass tolerates severe defoliation (LH treatments) also by increasing TAR and thus tiller density

Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

The meat of rabbit is one of animal protein sources. Prerigor meat is having a better quality in processing the meat especially for meatballs, however, the availability of this prerigor meat is difficult to obtain. Therefore, the use of postrigor meat could be used with consequently that should be add by a binder such as starch or others binder. Sago flour was not often used as binder, the present study was conducted to know whether the quality of rabbit meatballs using sago flour as a binder similar of that the meatballs using starch as a binder. The design of this study was completely randomized of factorial pattern 2 x 5 with 3 replications. The first factor was the condition of rigor (prerigor and postrigor), while the second factor was the combination levels between starch and sago flour (30% starch, 30% sago, 15% starch +15 % sago, 20% starch +10% sago and 10% starch +20% sago). The strength of meatballs using compression method, cooking loses, and the microscopic structures of rabbit meatballs were test in the study. The results of this study showed that different rigormortis condition of the meat affected the quality of rabbit meatballs, in terms of strength, cooking loses, and microscopic structures. The addition of a combination of starch and sago at a different levels influenced the quality of meatballs in terms of strength, and microscopic structures. The best meatballs quality was obtained by using prarigor meat with 15% starch +15% sago flour.

Publisher : Fakultas Peternakan, Universitas Hasanuddin, Makassar

Goat milk is a liquid medium having a very complete composition, but it can not last long when stored at room temperature. Milk stored at room temperature can be easily spoiled if it does not receive special treatment such as pasteurization. The purpose of this study was to obtain the right temperature and time in the processing of pasteurized milk. The experiment was carried out according to completely randomized design consisted of 3 treatments and 5 replications. The treatments of this research were the method of pasteurization , i.e. A1 = LTLT (Low Temperature Long Time, temperature of 65oC for 30 minutes) A2 = HTST (High Temperature Short Time, temperature of 75oC for 30 seconds) and A3 = Pasteurization UHT (temperature of 81oC for 30 minutes). The observed parameters were color, smell, taste, gravity weight, pH, acidity and the reductase score. The results of the study showed that different pasteurization methods had no significant effects (P>0.05) on the color, smell and taste of the goat milk, but significantly affected (P <0.05) gravity weight and lactic acid percentage. Similarly, the treatments did not have significant effects (P>0.05) on the reductase score of pasteurized goat milk.
