Efek Pemanasan Limbah Udang Yang Direndam Dalam Air Abu Sekam Terhadap Kandungan Nutrisi Dan Energi Metabolis Pakan

The experiment was conducted to examine the eilect of soaking and steam heat treatment of shrimp heads waste (SHW) on nutritional quality. The objectives of this research were to determine wether the effect of the shrimp heads waste were treated in 10% of dusk rice husk solution with five level of length of steam heat (control; 0; 15; 30; 45 and 60 min) on the improvement of its the nutritive value. The feed was soaked for 48 h prior to steam heat The experiment was designed in Completely Randomized Design of 6 x 3.The results showed that there was significant effects (P < 0.05) length of steam heat to dry matter, crude protein, fat, ash contens and metabolizable energy of SHW. Increasing length of steam heat was caused reduce dry matter, crude protein, fat contens and metabolizable energy of SHW. Based on comparative cost analyses and nutritive value indicated, the best treatment was filtered of the dusk rice solution 10% and length of steam heatfor 45 min

Penggunaan Tepung Limbah Udang Yang Diolah Dengan Filtrat Air Abu Sekam Dalam Ransum Ayam Broiler

The objective of this study was to measure the effect of different levels of shrimp head waste (SHW) substituting fish meal (FM) in broiler diets. FM is the sole crude protein from animal sources. A control fish meal broiler diet and four different levels of SHW substituted for crude protein FM were fed to CP 707 Arbor Acres broiler strains from day old chick to four weeks of age. The crude proteins FM were replaced with 0 (R0); 25 (R1); 50 (R2); 75 (R3); and 100 (R4) percent of crude protein SHW. The five treatments were assigned to completely randomized design. Feed consumption, body weight gain, feed conversion and carcass percentage were recorded to measure the performances. The results of Duncan's revealed that feed consumption, feed conversion and carcass percentage were not significantly different with increasing level of SHW as substituted crude protein FM in broiler diets. However these parameters in bird fed 100 % SHW diets did not differ from those in birds fed 16 % FM (7.32% crude protein from FM). While body weight gain decreased with increasing levels of SHW in broiler diets (R4). The decrease body weight gain may be due to the decreased feed intake and amino acid in balance and the increased chitin content in the diet. The conclusion of this experiment that SHW can be used as a protein source in broiler diets up to 75% to replace FM

Pengolahan Limbah Udang untuk Memperoleh Bahan Pakan Sumber Protein Hewani Pengganti Tepung Ikan

The objective of this study was to measure the effect of preparation the shrimp head waste to poultry feed. The experiment was conducted to examine the effect of soaking and steam heat treatment of shrimp heads waste (SHW) on nutrient and nutritional quality. The treatment is soaking and length of steam heat the shrimp heads waste. The experiment was designed in Completely Randomized Design, using factorial (3 x 3) with three replication. The first factors was three level concentration of the dusk rice solution (C1 = 10%; C2 = 20%; and C3 =30%), and the second factors was length steam heat ( W1 = 30 min; W2 = 45 min; and W3 = 60 min). Feed was soaked for 48 h prior to steam heat. The results showed that there was no interaction effects (P > 0.05) between concentration of the dusk rice solution and length of steam heat to dry matter (DM), crude protein (CP), lipid and fiber contents of SHW but length of steam factors was significant (P<0.05) to dry matter, crude protein, lipid and fiber contents of SHW and digestibility coefficient (in-vitro) of crude protein. There were interactions (P<0.01) concentration of the dusk rice solution and length of steam factors to chitin contents. There are no significant differences on metabolizable energy but nitrogen retention and protein digestibility was found to be significantly (P<0.05) between the SHW processed than unprocessed. Based on comparative cost analyses and nutritive value indicated, the best treatment was filtered of the dusk rice solution with concentratin 20 % and length of steam heat for 45 min

Berbagai Teknik Pengolahan Terhadap Kualitas Ikan Tongkol (Eutynnus SP) Afkir Sebagai Pakan Ternak

Rejected little tuna (Eutynnus sp) is alternative feed ingredient which same quality to commercial fish meal and the price is relatively cheaper. The aim of this research were to study the interaction between the salt level with time of steaming on the nutritional content (dry matter, crude protein, extract ether, crude fiber, calcium and phosphorus) of rejected little tuna meal. The experimental design was completely randomized design (CRD) 3 x 3 factorial pattern with 3 replications. The first factor was level of salting (A) (A1 = 2.5 %, A2 = 5.0%, A3 = 7.5%) the second factor was times of steaming (B) (B1 = 15 min, B2 = 30 min, B3 = 45 minutes). The results showed that the interaction between the level of salt to the time of steaming can maintain quality of rejected little tuna fish processed, it was seen with increasing of nutrient content of crude protein of rejected little tuna (50.16-64.42%), and the processing of rejected little tuna by salting and steaming highly significant effect (P <0.01) and there is a higly significant interaction (P <0.01) through the on dry matter and extract ether rejected little tuna processed. In conclusion, the processing of rejected little tuna by salting and steaming can maintain quality of rejected little tuna, it was seen with increasing of nutrient especially on crude protein (50.16-64.42), so that it can be used as animal feed

Penggunaan Urea Sebagai Sumber Nitrogen Pada Proses Biodegradasi Substrat Lumpur Sawit Oleh Jamur Phanerochaete Chrysosporium

The research was conducted to study the biodegradation capability on palm oil sludge substrate by Phanerochaete chrysosporium with increasing urea as nitrogen source. The experiment was designed using Completely Randomized Design (CRD) with 5 treatments and 4 replications, namely : U-0 = 0,0 % Urea, U-1= 0,5 % Urea, U-2 = 1,0 % Urea, U-3 = 1,5 % Urea and U-4 = 2,0 % Urea. The observed variables were the amount of spore, C/N ratio, pH, crude fiber, crude protein, lignin, cellulose and enzyme activities. The result of this study showed that added urea were significantly (P&lt;0.01) crude fiber, crude protein, lignin, cellulose and enzyme activities. The use of urea on the first level amounting to 1.5 % in palm oil sludge can help Phanerochaete chrysosporium to reduce crude fiber to (30,71%), lignin (29.89 %), cellulose (36.42 %) and it can increase the content of crude protein to (34.50 %), reduction sugar and enzyme activities

Optimization of Nutrient Medium for Pediococcus acidilactici DS15 to Produce GABA

Nutrition is an essential factor for microorganisms to grow and survive. Carbon and nitrogen sources are used in producing primary and secondary metabolites. Gamma-Aminobutyric acid (GABA), a non-coded amino acid, is a secondary metabolite which acts as an inhibitory neurotransmitter of the central nervous system. Pediococcus acidilactici DS15 is a bacterium belonging to the order of Lactic Acid Bacteria. This study aimed to determine the effects of nutrients including glutamate, nitrogen and carbon sources on GABA production by Pediococcus acidilactici DS15. The tests were carried out using a range of 30 mM, 40 mM, 50 mM, 60 mM, and 70 mM glutamate as inducer and carbon sources in the form of peptone, yeast extract, skim milk, NH4NO3, KNO3, whey tofu and soy milk as nitrogen sources, and then glucose, lactose, maltosa, sucrose, palm, and cane sugar as carbon sources. The best sources of both will be tested with levels 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100% for nitrogen and 1, 3, 5, 7, 9, 11, 13 and 15% for carbon. The results of this investigation revealed that the addition of 60 mM glutamate caused the higher amount of GABA production and the best source of nitrogen and carbon for Pediococcus acidilactici DS15 were 100% whey tofu and 15% palm sugar, respectively. Production rate of GABA by Pediococcus acidilactici DS15 could reach up to 311,485 mg / L
