Judul: Performan Ayam Broiler yang Diberi Pakan Bentuk Pelet Berbahan Baku Wheat Pollard Hasil Olahan Enzim Cairan Rumen
Abstrak: High quality of feedstuff is very important to support animal productivity. Corn is the main energy source for broiler chickens. Due to its supply and high price probiems from local corn. We recommended wheat pollard as alternative feed of sourch energy like corn. Wheat pollard as alternative has high crude fiber that disturbs digestion for broiler chickens. So, supplementation of enzymes from rumen liquor may increase the quality of wheat pollard. More over, steam pelleting of diet containing the wheat pollard may improve its quality. The research was conducted to study of performance of broiler feed pelleted diet containing with wheat pollard processed by enzymes from rumen liquor. We were used 360 broiler chickens Arbor acres strain age 21-35 days. The animals were devided into 36 group and assigned to one of the nine diets treatments i.e : PI (Feed with enzymes dossage 0 U/kg and stearn pelleting at temperature 60°C), P2 (Feed with enzymes dossage 0 U/kg and stearn pelleting at temperature 80°C), P3 (Feed with enzymes dossage 0 U/kg and steam pelleting at temperature 100°C), P4 (Feed with enzymes dossage 620 U/kg and stearn pelleting at temperature 60°C), P5 (Feed with enzymes dossage 620 U/kg and stearn pelleting at temperature 80°C), P6 (Feed with enzymes dossage 620 U/kg and stearn pelleting at temperature 100°C), P7 (Feed with enzymes dossage 1,240 U/kg and stearn pelleting at temperature 60 QC), P8 (Feed with enzymes dossage 1,240 u/kg and steam. p.elleting at temperature 80 DC) dan P9 (Feed with enzymes dossage 1,240 U/kg and stearn pelleting at temperature 100°C). Water and feed were given ad libitum.

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.
