Abstract

A hovercraft is an amphibious vehicle that works on an air cushion, capable of traveling on land and water terrains. This vehicle is driven by two systems, namely the lifting system and the propulsion system. The propulsion system functions to produce a thrust that will drive the hovercraft vehicle forward. The thrust is influenced by engine speed, transmission, shaft rotation, fan design, air flow speed, flow rate mass, and air discharge. This research method is carried out by varying the engine speed, starting from 1000rpm, 1200rpm, 1400rpm, 1600rpm, 1800rpm, 2000rpm, 2200rpm rotation. The results of the research and data processing showed that the higher the rotation of the shaft, the greater the thrust generated. Where at a minimum engine speed of 1000 rpm, the shaft rotation of 436 rpm produces a thrust of 11.794 Newton. Whereas at the maximum 2200 rpm engine speed, the 1060 rpm shaft rotation produces a thrust of 87.664 Newton.

Abstract

Wear is an important factor in reducing the function of engine performance including limiting the service life and performance of various engine components that rub against each other directly, this results in increased maintenance costs. In this study aims to determine the rate of straight gear wear with SCM 440 material from the influence of load and shaft rotation. Experimental research methods with variables of 200 rpm, 500 rpm and 1000 rpm and load respectively 0, 5, 10 kg, from the test results obtained the highest value of power at 1000 rpm and 0 kg load, while for the lowest wear value obtained at 200 rpm and a load of 5 kg, this is due to the misalignment factor in the drive shaft and being driven, this can be seen from the average wear position located at the end of the gear that is in direct contact between the gear and the gear is moved, so that in rotation high and without loading the shaft rotation is not balanced, but at high rotation and with a certain load imbalance rotation due to misalignment can be suppressed and produce a low wear value.

Abstract

This research aims to find out how much capacity that could have produced a conveyor according to the rpm speed of the motor and conveyor dimensions as well as to  determine the selection of the components that are used as system power supplier. This research was carried out based on the calculation of the design of conveyor design guide book and catalogue containing components of belt conveyor. Results of the design  is to be used as a guide for designing a conveyor to transport box containing intravenous fluids in PT XY. After the design resulted in two conveyors with 22.5 m long dimension, 40 cm wide belt and 0.5 m / s speed with inclination angle of 300 and 250. The conveyor has a carrying capacity of 300 boxes / hour (4.3 ton / jam). For power supply systems used 1.5 kw AC motor, WPX 80 type gearbox reducer ratio 1:10 s / d 1:60, S 400/4 type belt, drive pulley ???? 500 mm, roller idler ???? 89 mm, take-up type screws, transition roller chain number 40, number of teeth Z1= 21 and Z2=50, sprocket ???? 90.5 mm and ???? 209.5 mm, SAE type 10 oil (43 cSt, 200 SUS at 37.80C).

Abstract

The use of hydraulic systems for various applications supporting work equipment is very widely used because of the nature and strength of the good and easy in its design. Hydraulic tracking can be widely applied in various needs. The principle of this work tool is designed for the release of bearings / mounting on a shaft or a ball bearing house vertically or horizontally. From the results of the hydraulic tracking planning analysis using solid works software, in this simulation to find static nodal stress (the received tensile strength) obtained the highest load is shown in the orange part of the tool with a stress value of 17.49 million N / m2, the load experienced is only 15% of the permitted maximum limit of 24,800,200,000 N / m2.then the strain that occurs in the highest value is shown on a scale with an orange of 0.03946 mm on the upper beam component, that value 1 mm means that the hydraulic frame tracking can be used properly.

Abstract

Compressor is a compressing device or compressing air in other words a compressor is a compressed air generator. Because of the compression process, air has a higher pressure compared to environmental air pressure (1 atm). In this Final Project the compressor is planned with an output pressure of 140 bar, a flow rate of 5000 m3 / hr, 4 levels, a shaft rotation of 15000 rpm. In the compressor planning, TURBO 10 CF software is used. Input from the software is the flow rate and pressure of each level. As output is the impeller diameter, the output pressure of each impeller. Power of each level. The average impeller diameter is 596 mm. The air coming out of each level is cooled. The cooling system is not planned in the final project.

Abstract

The development of technology, especially in the field of modern and sophisticated automotives, one of the technologies being developed is EFI (electronic fuel injection). EFI is a fuel spraying system whose performance is electrically controlled in order to obtain the value of the mixture of air and fuel that is in accordance with the needs of the combustion motor, so that optimal motor power can be obtained with minimal fuel use and has an environmentally friendly exhaust gas. The function and function of fuel injection system of the EFI system on the vehicle consists of three systems, especially the fuel system, the induction system and the electrical control system. The injector is an electromagnetic nozzle whose operation is controlled by the computer, the injector is equipped with a heat insulator on the inlet or on the cylinder line which is close to the input line. The way the injector works is as well as when the ECU sends its signal in the form of a solenoid coil then it must be converted into a magnet which will lift the nose to its upper position, so that the injector gate will open and the high pressure fuel supplied by the fuel pump can come out or spray gently. The electric injector is one of the only substances used to spray and atomize gasoline into the burner according to the Firing Order (FO) sequence.
