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.

Judul: Dynamics Model for Rural and Urban Economic Growth
Abstrak: Lewis theory of structural change has focused on mechanisms that allow countries to transform their domestic economic structure to a more modern economy. The proposed model deals with the mechanism of interaction between rural and urban Economic. This model is concerned with the process of labor transfer from rural to urban areas. This study aims to model the dynamics of economic growth in rural and urban areas, including determining the equilibrium solution and to carry out simulation of the model. The simulation results show that the transfer of labor from rural to urban areas will increase the rate of change of capital so that structural changes can be realized. In addition, increased propensity to save in rural areas will also accelerate structural change
