Abstract

Aerodynamic characteristics are a very important thing in the field of aerodynamic application science which is intended to obtain maximum performance from an object shape. This analysis was carried out to determine the effect of fluid flow velocity on symmetrical model aircraft wings. In this research, analysis of aerodynamic characteristics was carried out by testing an object in the form of a symmetrical model of an airplane wing that was supplied with air using a Wind Tunnel and Smoke Tunnel, so that the comparison and air flow produced could be seen. In connection with this, it is certain that we will not be separated from the topic of aerodynamics which is closely related to the characteristics of the object when flying in the air, which in the end will be able to draw conclusions regarding the aerodynamic characteristics of the object. In this final assignment, what will be discussed further are the aerodynamic parameters which in the world of aviation we usually know as the lift coefficient and also the drag coefficient. The method used is the simulation analysis method. The simulation was carried out by making a symmetrical aircraft wing model, then testing it using the Wind Tunnel and Smoke Tunnel tools. The purpose of this analysis is to determine the pressure characteristics of fluid flow on a symmetrical aircraft wing with a speed of 20 m/s and variations in angle of attack ranging from -20°, -10°, 0°, 10°, and 20° to the lift coefficient and drag coefficient and to determine the effect on each wing of a symmetrical model aircraft given speeds ranging from 12 m/s, 16 m/s, and 20 m/s which are fed by air in a wind tunnel using the drag coefficient and lift coefficient methods.

Abstract

Comfort in a vehicle usually uses an air conditioning system. AC is a type of machine that works following a thermodynamic cycle, namely the vapor compression cycle. A refrigeration machine depends on the ability of the compressor to meet the amount of refrigerant gas that needs to be circulated. The compressor is a tool for pumping cooling material (refrigerant) so that it continues to circulate in the system. The performance of the car's AC compressor is controlled by the thermostat, where the thermostat signals whether it is active or not active depending on whether the temperature in the car has been reached or not.This research includes variations in cooling load with a fixed compressor rotation of 759 RPM, each variation of cooling load is tested with a fixed compressor rotation of 759 RPM using one R-134a refrigerant to determine the COP, then this research is continued by calculating the on-off time of the compressor. to save energy used.The results of the research carried out show that the greater the cooling load, the greater the compressor inlet pressure and compressor outlet pressure (∆P = P1 – P2).

Abstract

TNI-AD is an army unit whose mobility is mostly in the mainland area. In mengkaver all regions of Indonesia, requires a vehicle that is able to cross all terrain both flat terrain, and bumpy terrain that is difficult to pass by ordinary vehicles. As well as being able to transport personnel with a high level of mobility in the field of operation, so it requires a truck that is tough enough to overcome it. No less important is also the ability of the body of the truck, so that in transporting personnel and logistics must be strong and use materials made of armored are. This study aims to analyze and test the material from the content of the type of steel used in the truck body Unimog on physical and mechanical properties, when heat treated with a certain temperature.Steel type ST40 steel coating on military Unimog trucks has high hardness, can be seen from the results of hardness tests and tensile tests carried out in this experiment. The steel is broken when the steel is pulled with a strength of 5910 kg after undergoing a heat treatment process without being welded. Then the steel is broken when the steel is pulled with a strength of 4360 kg after undergoing a welded heat treatment process. Pure steel containing carbon content below 1% is a type of high quality steel, so it is suitable for use as a steel coating on the body of military vehicles.

Abstract

This research is about comparing the physical and mechanical properties of motorbike piston made in China (Kanzen) and motorbike pistons made in Japan (Honda GL). The aim is to find out which material structure is better between motorbike piston made in China and motorbike piston made in Japan. Because in field use Japanese motorbike pistons are superior to motorbike piston made in China.The piston is an engine component that changes or transfer combustion pressure into straight motion (sliding) which then, through the piston rod, piston rod and crankshaft, converts the straight motion of the piston into rotary motion. This piston has an aluminum alloy composition with the dominant elements, namely Mn, Zn, Ti, Cr, Pb, and Sn.From the test of the material composition of these two pistons, the material elements are almost the same, but the Honda GL motorbike pistons is better than the Kanzen motorbike pistons, judging from its elements. From the hardness test, it turns out that motorbike pistons made in China (Kanzen) are superior to pistons made in Japan (Honda GL) but that doesn’t mean that hard is good for the piston, then from the micro structure the piston of Japanese motorbikes (Honda GL) are better than Chinese motorbikes (Kanzen) because the crystals spread out so that they can cause cracks in the piston more quickly.

Abstract

The engine capacity of a vehicle, especially a diesel engine, is greatly influenced by the fuel used, in this case the diesel used. What is meant by engine capacity is the performance produced by the engine, including the power produced by the engine, the specific fuel coefficient, and others. Therefore, choosing the right diesel will certainly make the engine able to produce good performance but diesel consumption remains efficient. So an alternative replacement is needed when the diesel runs out, one of which is using biodiesel. Biodiesel is a fuel made from base oil or renewable oil sources that are transesterified lipids into the desired ester by removing fatty acids. So biodiesel is the closest alternative to replacing fossil fuels which are the main source of transportation energy. Based on the test experiments of diesel engine performance using biodiesel and Shell diesel, namely at 2500 rpm, 2300 rpm, 2000 rpm, 1800 rpm, and 1600 rpm, there are differences in engine performance, although not significant, but can still be used as a guideline for choosing the right fuel, especially for vehicles in the Indonesian Army and if later biodiesel is known to the wider community, it can be used as an alternative fuel and can be considered to be used as fuel for diesel vehicles in the Indonesian Army.
