Abstract

The effect of different water spraying level and storage period on endurance of pellet broiler finisherABSTRACT. The storage is very important in a farm management, because this activity can take care of feed stability which enough and preferable to be consumed by animal and also strive for animal food availability continuously. The purpose of this research is to know the water spraying level and variation of storage period against the endurance of pellet broiler finisher ration. This research was designed by a Completely Randomized Design Factorial with two factors (water spraying different level and storage period) with four replicates, the significant result were analyzed by orthogonal contras test. On this experiment, the different level of water spraying (0, 3, 6%) were conducted during mixing at conditioning process, and then the ration were stored until four weeks to study the endurance of pellet e.g.: water content (%), water activity, specific gravity (ton/m3), pellet durability index (%), attack of insect. The water content, specific gravity, and pellet durability index was very significantly (P0.01) reduce by water spraying different level, and not significantly on water activity. The storage period showed very significantly (P0.01) increase the specific gravity, pellet durability index, and the insect attacks, and significantly (P0.01) decreased the water activity, but not effect on water content. Interaction among spraying level and storage period is very significantly (P0.01) on the values of water content, water activity, specific gravity and pellet durability.

Abstract

The effect of reduction of maize as starch source on flow rate of pellet in continuous production processABSTRACT. This experience was conducted to determine effect of reduction of maize as starch source on flow rate of pellet in continuous production process. Design of the experiment used was a completely randomized design with 3 treatments and 3 replicates. The data is analyzed by using of ANOVA and if there is a significance among treatments would tested using by contrast orthogonal. The variables observed were angle of repose, loose bulk density, compacted bulk density, and flow rate. The results showed that the reduction of maize as starch source did not give the significant effect on the variable that observed. The analyzed angle of repose showed variation 24.200 to 25.690, loose bulk density showed variation 621.6kg/m3 to 658kg/m3, compacted bulk density showed variation 668.3kg/m3 to 676.8kg/m3, and flow rate showed variation 449.69kg/minute to 491.41kg/minute. Based on the result that the reduction of maize as starch source (corn, sorghum, menir) did not give the significant effect on flow rate of pellet and the pellet treatment with menir has the fastest pellet production time so flowability pellet from pelleter to material hadling (bucket elevator) machine is faster. As higher the values of flow rate, so the time of material movement from bin to the package is shorter.

Abstract

The physical characteristic test of broiler ration pelleted that added of onggok as binder with water spraying processABSTRACT. Pellet is a kind of solidified and mechanically compressed feed. Problem frequently rise is that pellet shape is easily damaged, brittle, and broken during production, transportation and storage processing. The purpose this study was to know the influence of onggok addition as binding agent with 5% water spraying on the physical characteristic of pellet form ration.The data were analyzed by analyzed of variance and the significant experiment results would be examined by orthogonal contrast test. The treatments consist from the first experiment were: A1 = basal ration + 0% spraying water, A2 = basal ration + 5% spraying water, A3 = basal ration + 10% spraying water and A4 = basal ration + 15% spraying water. The best result from the first experiment would be used for the second experiment, the treatments second experiment were: R1 = basal ration + 5% spraying water + 0% onggok, R2 = basal ration + 5% spraying water + 2% onggok, R3 = basal ration + 5% spraying water + 4% onggok and R4 = basal ration + 5% spraying water + 6% onggok.The parameters were water content, water activity, specific gravity, loose bulk density, compressed bulk density, angle of repose, modulus of fineness, average particle sizes and the durability of pellet form. The conclusion of the experiment that added of onggok as binder significant influenced of the characteristic physical pellet, i.e.: increased loose bulk density, compressed bulk density, modulus of fineness, average particle sizes, and durability of pellet, but decreased specific gravity, water content, angle of repose and water activity.

Abstract

The effect of using synthetic binder on physical quality of chicken rationABSTRACT. The purpose of this study was learn about the influence added lignosulfonate and bentonite by some processes production on physical characteristics of pellet form ration. The experimental design had used a Randomized Completely Design with 4 x 3 factorial and 3 replocats. Factor A were processes production, i.e : A0 = without processing, A1 = added 5% water spraying, A2 = added 5% hot water spraying and A3 = steam 45 minute on 1000C and pressure 1.7-1.8 kg/cm2. Factor R were added binder, i.e: R0 = control ration, R1 = control ration + 1.25% lignosulfonate and R2 = control ration + 2.5% bentonite. The parameters observed were water content, specific weght, specific density, packed specific density, angle of repose, particle size, water activity and durability of pellet. Result from this study showed some steam process by autoclave 45 minute and added binder lignosulfonate and bentonite was obviously influence specific weight, specific density, packed specific density, angel of repose, particle size, water activity and durability of pellet by percentage was 0.67 cm, 0.68 g/cm3, 0.75 g/cm3, 1.57 g/cm3, 26.990, even the water activity 0.81 wasnt good. Added binder lignosulfonate and bentonite was obviously particle size was 0.67 cm and durability of pellet was 99.99%. Added lignosulfonate and bentonite by some process given the best on durability if it compared with commercials ration. The purpose of this study was to learn about the effect of using binder lignosulfonate and bentonite during six weeks period. The experimental design used a Randomized Completely Design with 3 x 4 factorial and 3 replications. Factor B was storage term (0. 2. 4 and 6 weeks). The parameters observed were water content, water activity factor higroskopic, particle size, specific density, bulk density, packed bulk density and pellet durability. The storage term very significant (P0.01) influenced the water content and increased the water activity, decreased the factor higroskopic, particle size, specific density, bulk density, packed bulk density and durability of pellet. The lowest water content was 10.82% in 6 weeks. The lowest water activity was 0.74 in 0 week. The highest particle size was 0.669 cm in 0 week. The highest durability of pellet was 99.95% in 0 week. The highest specific weight was 1.30 g/cm3 in 2 weeks. The highest specific density was 0.738 g/cm3 in 0 week. The highest packed density was 0.738 g/cm3 in 0 week and the lowest factor higroskopic was 0.79% in 2 weeks.
