Judul: Protein isolation from palm kernel meal and its biological value as alternative of soybean meal in quail (Qoturnix-coturnix japonica)
Abstrak: Local feedstuffs are rarely available as soybean meal (SBM) alternative in poultry diet. Consequently, the amount of imported SBM is increasing as the increase of poultry population. Palm Kernel Meal (PKM), one of by products from palm oil processing industry, has high potency as feedstuffs due to its availability. PKM, however, has combination problems of shell contamination, containing high non starch-polysaccharide (NSP) dominated with mannan molecules, and low protein content which causes the utilization of PKM in poultry diet is very limited (< 3%).

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.

Judul: Tinjauan Matematis pada Model Makroskopik dan Mikroskopik Arus Lalu-lintas
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.
