Abstrak: The palm oil industry has a main product and a byproduct that can be used as a feeding. One of the product that has not been widely studied is the palm kernel powder. The purpose of this study was to evaluate the effect offeeding ration containing palm kernel powder on carcass percentage, commercial cut, and abdominal fat of broilers. There treatments were; P1 (control), P2 (ration contained palm kernel powder and pollard), P3 (ration contained palm karnel powder and rice bran) with 6 replications. The results showed that the percentage of carcass and commercial cut of broiler fed palm kernel powder (P2 and P3) was lower than control, but increased commercial cuts (thighs, upper thigh, wings, and back). Abdominal fat of P2 was higher compared to P1 and P3.Feeding palm kernel powder in the diet decreasedcarcass percentage and increased commercial cuts except the breast and abdominal fat.

Abstrak: The use of palm kernel in the diet should be limited, because it contains high crude fiber and crude fat and low protein. The objective of this study was to determine the effect of feeding diets containing palm kernel powder added pollard or rice bran on percentage of internal organs in broiler chickens. The treatments were as follow : P1: control, P2: feed A (feed containing palm kernel powder added pollard ), P3: feed B (feed containing palm kernel powder added rice bran). The results showed that percentage of weight of the liver and bile were not significantly affected by the treatment. However the treatments significantly (P<0.01) affected the percentage of weights and relative lengths digestive organs where the percentage of weights were higher, and relative lengths were longer for treatments compared with that of control, while P2 and P3 results are comparable, except pancreas and colon. It is concluded that feeding diets containing palm kernel powder added pollard or rice bran produces a comparable percentage of internal organs in broiler chicken, but not to the pancreas and colon where feed containing palm kernel powder added pollard higher than feed containing palm kernel powder added rice bran.

Abstrak: Traffic flow phenomenon can be described through mathematical model such as continuous dynamic model with an ordinary differential equation so that it can be solved with integral factors. In this paper three simple models of traffic flow are discussed, i.e, two macroscopic and one microscopic models. Macroscopic model formulates dynamics of the traffic flow that occurs on a large number of vehicles on a road. While the microscopic model explains drivers’ behavior in their interaction with other vehicles ahead, i.e, car-following model. This paper shows the existence of ordinary differential equation found in the traffic flow model and indicates some different representations in the context of the same model. It also reviews a simple model of traffic flow along a single link, which leads to some unexpected results, i.e, it can express the solution model in term of link outflows as well as trip time. In the microscopic model, simulation is done to illustrate the behavior of the drivers with a sensitivity coefficient as a benchmark parameter.
