The purpose of this research is to design and develop dummy (anthropometric test dummy) for motorcycle frontal collision test. The conceptual design of dummy is male aging between 25-55 years old 6 pieces of rib and deformable 76.2 mm. In order to performance test it was classified into 2 testing by static testing and dynamic testing. For static testing the energy absorption behavior between force and deflection or “ static curves” is determined. While dynamic testing is considered to the energy absorption behavior between forces and several velocities or dynamic forcedeformation curves impact acceleration impact force on sternum and injury severity with the relationship of viscous in velocity function. The results of the energy absorption behavior on chest of dummy from static testing the tendency of chest deflection is relatively low during the initial force and suddenly increasing when rise to the critical point. This behavior is similar to the energy absorption of the human chest. Therefore the design features of this test dummy can reflect behavior that is close to the human anatomy. In case of dynamic testing it is discovered the ability of the dummy testing to absorb up to 560 J impact acceleration 3 8 . 4 3 g impact force on sternum 5 . 0 9 4 kN. The viscous in velocity function is 0 . 8 2 5 m/ s which compared to injury severity at AIS3+ ( or higher than serious injury) . Therefore the dummy design in this research project corresponds to the collision test of a motorcycle.

A design and development of powertrain module crash test using with the motorcycle crash test is aim to create a special tool for automotive assessment and safety engineering based on the realistic test. In order to main system of power module tester is consisting of powertrain system using electrical motor transferring system using chains and gears and control direction system using dual rails respectively. Based on powertrain module tester performance crashing speed relative angle between target and distance before crash are regarded. Nevertheless the result of testing performance was conducted to statistic hypothesis test by Mean Absolute Deviation: MAD Standard Deviation: SD Mean Square Error: MSE Mean Absolute Percent Error: MAPE and Root Mean Square Error: RMSE. The results of this approach discovered that the crashing speed was the highest error with 96% and the lowest was distance before crash. Furthermore it was corresponding to the statistic hypothesis test. However the result of the error was influence of the rails distance which limit by funding. In case of crash energy the mean of energy was appeared on 10.978 J. Whereas the tendency of variable was similar to polynomial equation.

The purpose of this research is to study on variables affecting fuel injection performance of biodiesel fuel injection and pyrolysis fuel. To test for variables affecting the fuel injection performance of biodiesel fuel injectors and pyrolysis fuel. By experimenting and modeling using computer programs to compare results. Finally for to use the information in the design of the car nozzle to work well with Biodiesel and pyrolysis fuel. The tested fuels which are pyrolysis fuel Bio-diesel fuel and diesel fuel are tested by tester Anton Paar@ Stabinger Viscosmeter (model SVM 3000/G2) ASTM D341 standard. The result shown that the density of the fuel is increasing normally. However the viscosity of the diesel and biodiesel are strong increased whereas the reducing of temperature is unaffected to the pyrolysis fuel. The fuel injection performance test showed that the density and viscosity of fuel were the major variables that affected the injection performance of the fuel. In case of using pyrolysis oil Injection performance is trend to higher other fuels and cold conditions.

This research aims to develop the coconut coir and fiber indoor acoustic and thermal insulation boards mixed with natural latex. The 5 ratios of coconut coir: coconut fiber: natural rubber were equal to 0.1: 0.9: 0.1 0.1: 0.9: 0.15 0.1: 0.9: 0.2 0.1: 0.9: 0.25 and 0.1: 0.9: 0.3 by weight. The indoor acoustic and thermal insulation boards were produced by knitting the coconut coir and fiber spraying the natural latex and heat compressing. The properties testing of indoor acoustic and thermal insulation boards included the density test water absorption test tensile strength test thermal conductivity test sound protection efficiency test and real usage test. From the results 0.1: 0.9: 0.15 ratio is the most suitable ratio of coconut coir and fiber indoor acoustic and thermal insulation board mixed with natural latex. The natural latex which putted in these indoor acoustic and thermal insulation boards can reduce the water absorption and increase tensile strength and sound protection efficiency.

System of The Provincial Electricity Authority using the grounding wire connected between the cable end and Surge arrester format it is connect the cable from the end of the cable set to the end of the Surge arrester and grounded wire that splits the ground between the cable connecting point and the Surge arrester format it is a separate grounding connecting point to the cable end and Surge arrester on both sides of cable riser pole by Computer program. Resulting from computer analysis and the comparison of line setting found that if setting line lead to ground and join with ending cable line and Surge arrester lead in to line voltage drop less than setting line to ground with separate line and Surge arrester.
