Abstract

Motorcycles are vehicles that have quite high economic value when compared to other vehicles. Motorcycles are made up of several constituent components, one of which is the use of final gear. The purpose of this study was to determine the amount of torque and the ratio of torque produced from the final gear size 13,14,15 on the new 2013 vixion motor. From the data obtained, the maximum torque when using the final gear size 13 = 15.24 Nm at a speed of 7.05 rpm. 14 = 15.49 Nm at 7.33 rpm and 15 = 15.91 Nm at 6.83 rpm. While the difference in the ratio of torque produced by the final gear (standard) size 13 and size 14, the difference in value = 0.22 Nm, the final gear size 14 is larger, the difference in the torque ratio between size 14 and size 15, the difference in value = 0.35, is greater than 15 size 14, the difference in the torque ratio between size 15 and size 13 is the difference in value = 0.57 Nm, which is 15 greater than size 13

Abstract

Semen Padang Indarung IV unit has a screw compressor type compressor unit to produce high pressure air. In its operations, one of the Atlas Copco type compressor units often experiences over heating problems, namely the working temperature exceeds 1000 C. The method used is trouble shooting the compressor system, such as checking the lubricating oil, pressure, valves, working temperature and cooling system. , as well as overhaul maintenance actions if necessary. Based on the research results, it was found that the factors that cause overheating of the compressor are: Dirty air quality affects the condition of the air filter for air supply, limited space for placing the compressor causes the air supply to decrease, the oil filter has passed its useful life and is not suitable for use, and the oil cooler is clogged with scale, which hinders the oil cooling process. Based on this damage, recommendations for maintenance activities on the Atlas Copco Compressor are: maintaining air quality, periodically cleaning the tubes in the oil cooler, replacing the new oil filter according to compressor specifications, as well as comprehensive maintenance measures

Abstract

Compressor is one of the equipment on the ship in the process of smooth sailing for the purposes of starting the main engine and also functions to increase gas pressure, distribute air to other parts so that the process runs smoothly. MT Tanker Ship. Sea Serenity is a goods delivery ship. On this ship, the compressor is used to carry out maneuvers, namely the main air compressor which produces air pressure of 12 bar for 10 minutes, but it should only be 5 minutes, meaning the compressor performance is not optimal. The causes of decreased performance in the compressor are: Dirty/clogged air valve, wear of the piston ring/housing, non-functioning of the low pressure and high pressure suction valves. Recommendations for maintenance activities on the LSHC-50A air compressor are: Ensure air circulation to the compressor room is clean/free from dust or dirt, add an air filter, and maintain room temperature stability (providing air conditioning). Maintain the cleanliness of the blower, check the oil filter, replace damaged pistons, and replace new piston rings according to compressor spare parts every 6000 working hours

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

Mesin diesel merupakan bentuk pembakaran dalam (internal combustion engine) dengan prinsip kerja penyalaan bahan bakar yang dilakukan oleh suhu secara kompresi di ruang bakar. Perawatan motor diesel pada kendaraan bermotor terutama pompa ijeksi sangat diperlukan. Tujun penelitian untuk mengetahui prinsip kerja injection pump, penyebab tersumbatnya injection pump dan mengetahui prosedur perawatan injection pump. Penelitian dilakukan dengan mengambil data tekanan penginjeksian pada Injection pump dan Injektor motor Diesel 6 silinder menggunakan tool set, nozzle pump tester, ragum dan test banch serta truck hino FM 260 JD sesuai spesifikasi yang ditentukan. Hasil dari penelitian ini pada analisis volume penginjeksian pada plunger didapatkan data dengan putaran 300, 500, dan 800 rpm secara berturut-turut yaitu rata-rata 3,6 ml, 19,3 ml dan 21,5 ml. Setelah dilakukan penyetelan pada tiap-tiap plunger, diperoleh hasil 2 ml, 20 ml dan 22ml dengan putaran yang sama secara berturut-turut. Perawatan injection pump dilakukan agar mencegah ketidak stabilan rpm dan runaway.

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
