Abstrak: Palm kernel meal (PKM) is a by-product of oil extractions of palm kernel. The use of PKM in the ration of monogastric animals is limited as a result of high fibre. The main objective of this study was to evaluated the performance of broiler fed diet containing PKM with or without screening. Two hundreds DOC were divided into 20 groups and assigned to one of four diet treatment i.e : P1 = treatment diet + 7.5% PKM without screening and adding grit; P2 = treatment diet + 7.5% screened PKM without adding grit; P3 = treatment diet + 7.5% screened PKM + 2% shell of PKM; P4 = treatment diet + 7.5% screened PKM + 2% commercial grit. Data from completely randomized design were analyzed variance (ANOVA). Feed and water were given ad libitum. The result showed that screened palm kernel meal decreased crude fibre (from 33.13% to 30.58%). However, screened PKM did not affect feed intake, body weight gain, and feed conversion. It is concluded that PKM with ot without screening did not affect broiler performance.

Abstrak: The aim of this research was to study percentage carcass and commercial cut of broiler fed diet containing screened or unscreened palm kernel meal (PKM). Two hundred day old chicks (DOC) of broiler strain Hubbard were used and kept for 35 days. The diet treatments were R1 = diet containing unscreened PKM, R2 = diet containing screened PKM, R3 = diet containing screened PKM plus shell of PKM as grit, and R4 = diet containing screened plus commercial grit in completely randomized design with four treatments and four replications. Water and diet were given ad libitum. The results showed that there were significantly different (P<0.05) among treatments on the final body weight and carcass weight where broiler fed R1 and R4 were higher body weight and carcass weight than those broiler fed R2 and R3. Percentage carcass, commercial cut and abdominal fat were not significantly different all on all PKM diets. It was concluded that screening PKM did not affect percentage carcass and commercial cut of broiler.

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.
