Judul: Performa Ayam Broiler yang Diberi Pakan Mengandung Bungkil Inti Sawit dengan atau tanpa Penyaringan
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 objective of this experiment was to determine the effect of feeding complete diet containing palm kernel powder that added pollard or rice bran on broiler performances. Experiment used 180 day old chicks (DOC) of CP 707 and reared for 28 days. The experiment used completely randomized design with 3 treatments and 6 replications consisting of 10 broilers in each replication. The treatments were: P1= feed control (100% commercial feed) without palm kernel powder, P2= Feed A (feed containing palm kernel powder + pollard), P3= Feed B (feed containing palm kernel powder + rice bran). The diet and water were given ad libitum. The results indicated that feeding palm kernel powder in broiler diet that added with pollard or rice bran decreased (P<0.01) feed consumption, final body weight, body weight gain and increased feed conversion rate. There were not significant differences between P2 and P3 treatments in terms of its effect on broiler chickens performance. The quality of feed containing palm kernel powder-pollard or palm kernel powder-rice bran could not substitute the commercial feed.

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
