Abstract

This critical shaft rotation test tool is used to calculate the maximum deflection of a steel shaft. Currently, the critical shaft rotation test tool still uses human power to operate it, namely by rotating the handle to read the rotation value. So the test results carried out are not effective and accurate. This tool uses an electric motor with ¼ HP power and 2800 Rpm rotation as the driving force. So that the results are more accurate, this tool is designed to use an electronic system (sensor) equipped with a digital counter. Making this critical rotation test tool for the shaft goes through several processes, namely, making a table or position of the critical rotation test tool for the shaft using a digital counter, selecting the disk (load), selecting the bearing (pillow block), selecting the electric motor, selecting the shaft, and selecting the voltage regulator. . The testing phase has undergone several testing stages and the results are as planned. The tool that has been made can be operated effectively and obtain results as planned, and its operation is very easy.

Abstract

This study aims to analyze the causes of overheating in Pertamax fuel pumps at PT. Pertamina Patra Niaga–Fuel Terminal Medan Group and determine the appropriate maintenance actions to prevent operational failures. Overheating in pumps can cause serious damage and operational disruptions that have the potential to disrupt fuel distribution. The methodology used includes collecting operational data, analyzing pump conditions using infrared thermography, and evaluating pump performance based on industry standards. The results of the study indicate that overheating is caused by several factors such as component wear, inadequate lubrication, and fluid flow instability. Based on these findings, several preventive and predictive maintenance actions are recommended, including maintenance rescheduling, improving the lubrication system, and implementing real-time temperature monitoring. The implementation of these maintenance actions is expected to improve pump reliability and reduce the risk of overheating in the future.

Abstract

The generator set on the ship has the function of supplying electrical power needs. MT Tanker Ship. Sea Serenity is one of the ships that delivers goods between islands. In operation, the diesel generator engine on the MT. Sea Serenity sometimes experiences problems resulting in blackouts. This research aims to determine the factors that cause damage as well as appropriate maintenance actions and the method used is trouble shooting. Based on the research results, it is found that the causes of damage are: Engine knock, engine exhaust smoke, problems with the injection pump, worn plunger, damage to delivery valve seat, injection nozzle interference, valve opening pressure too low, engine output unstable, worn piston rings. Maintenance carried out: Injection timing must be adjusted according to ignition sequence, set injection timing, replace plunger and delivery valve seat, set valve opening pressure, replace spring, and clean injection orifice. On unstable engine output, the control rack stroke must be checked. Perform regular oil changes and regular tune ups

Abstract

PLTU Teluk Sirih is a coal-fired steam power plant as an energy source that produces ash with a capacity of 2 . The compressor is a medium for transferring ash by using compressed air. The compressor used is a SCREEW OIL INJECTED SULLAIR LS20-150H compressor. Currently there is a decrease in performance on the compressor, which initially had a compression ratio of 1,600 Psia, polytropic head 14,500,599, capacity 10,938,438, flow rate 11,379,622 lb/s, efficiency 98.5%. After analyzing this compressor, the data obtained was a compression ratio of 1,540 Psia, polytropic head 13,805,166, capacity 10,950,733, flow rate 11,392,412, and efficiency of 95.3%. The reason is because the compressor room area does not have an active blower so that dirt/ash stuck to the radiator fins causes heat transfer to be hampered and this greatly affects the performance of the compressor parts to work optimally

Abstract

Slicing tempeh, which is generally done manually, can slow down the production process. Therefore, a tool was designed that is capable of slicing tempeh precisely, so that the results of slicing tempeh are more precise, efficient, save time, save labor, and reduce the possibility of work accidents. . In making this tempeh slicing machine, a ½ HP 1400 Rpm electric motor is the main driver, the rotation of the electric motor is transmitted to the cutting knife (circular knife), which will later be used to slice the tempeh. The tempeh slicing process is done by placing the tempeh on a sliding table slide. The basic materials used in making a tempeh slicing machine are 4x4 hollow iron, a dynamo adapter, and an electric motor. After the tool was ready to be used, the tempeh slicing machine was tested. The test was carried out for 10 seconds and produced 8 tempeh slices, 5 suitable tempeh slices and 3 unfit tempeh slices, so it could be concluded that the suitability of the tempeh slicing results was 68 percent

Abstract

Current technological advances have produced many products that aim to make human work easier. One of them is an iron burning tool that uses a blower as a tool used to increase or enlarge the air or gas pressure that will flow into the combustion container (furnace). The blower used is a 2 inch snail blower as a tool to increase the air pressure so that the air that is supplied can enlarge the burning flame. The furnace used is a drum coated with heat-resistant cement which can withstand the heat of the combustion fire so that the furnace does not melt. The frame materials used are hollow iron measuring 40 x 40 and angle iron measuring 40x40. For combustion, it uses coal as the main fuel and the blower itself as an air distributor so that it can produce the desired fire. Based on the test results in a metal burning furnace, a temperature of 340°C can be obtained as planned so that by heating the metal, various types of equipment can be formed as desired

Abstract

The design of this metal burning stove was made to speed up and make it easier for blacksmith craftsmen to produce quality products. Using this tool, blacksmith craftsmen can produce a stable flame in the metal burning process. Where the planning for a metal burning stove uses coal as the main fuel, because coal can produce a longer lasting fire compared to charcoal or firewood. The working principle of this metal burning stove is to use a machine tool that is driven by a blower to increase or enlarge the air or gas pressure that will transmit to the connecting pipe, and produce a stable fire so that combustion is faster and more efficient. The metal burning furnace planning process consists of: Power planning in the metal burning furnace planning p_d = 0.3 Kw, using a blower with a rotation of 2800 rpm, using 2 pipes as air conductors, the furnace volume is 7,385.28 m^3 and using a C18 castabble, weight 25 kg, cement resistance capacity 1800?.
