Abstrak: Ginger, meniran, temu ireng and sambiloto are plants which is used as feed formulation anti-avian influenza. Using that plants worry will change broiler physical properties and proximate. Design experiment is randomized block design with five treatments. Threre are control, crude dose 1, crude dose 0.5, extract dose 1 and extract dose 0.5. The parameters are the texture, color and proximate of broiler. There is no effect of treatment on the texture of the meat. The color of all treatments is red. Water and fat content of crude dose 1 is the lowest among other treatments. Crude dose 1 and dose 0.5 have the highest protein than the others. All treatment had profiles as fit as the profile of chicken meat should be.

Abstrak: Curcuma xanthorrhiza Roxb., Phyllanthus niruri, Curcuma aeruginosa and Andrographis paniculata Nees are used in feed formulation of anti-virus of the bird flu, may change description chicken blood profile. This study aims to describe chicken blood profile fed finisher period plus herbal formula as a natural antibiotic. Experimental design that used was a randomized complete design with five treatment groups; were the control, simplicia dose 1 and dose 0.5, extract dose 1 and dose 0.5. The parameters tested were Feed Convertion Ratio (kg/kg), mortality rate (%), erythrocytes numbers (millions/mm3), hematocrit value (%), hemoglobin levels (g%), leukocyte numbers (thousands/mm3) and differentiation (%), serum protein total (mg/ml). The 0,5 extract dose showed a significant effect on decreasing the number of erythrocytes, hematocrit, hemoglobin levels, monocyte values. There was no effect of the treatment on leukocytes numbers, heterophile and lymphocytes value, serum protein total. Eosinophils increased significantly in the treatment group of extracts dose 1. Highest mortality is in the simplicia dose 0.5, lowest feed efficiency found in the extract dose 0.5.

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.
