Abstract

The development of technology and industry has also affected the level of pollution. Side effects that are very influential on human health include the level of noise that comes out of the exhaust gas (exhaust). Sound pollution comes from either gasoline-fueled or diesel-fueled engine vehicles, especially in diesel engines. To reduce noise levels there are several ways that can be done; (1) Giving a silencer to the engine, (2) Designing a muffler on the exhaust gas line, (3) Placing the sound source in the correct position, and (4) Setting the engine operation and maintenance schedule. One way to reduce the noise level in a diesel engine is to trap a particulate trap installed in the exhaust gas (exhaust). This method can reduce the gas particles from combustion to the disposal process, so that the noise level can be reduced. The purpose of this study was to determine how much influence the installation of particulate trap made of brass metal in the exhaust of a diesel engine to the level of noise caused. This study uses a factorial type random design by varying the weight of the active ingredient of metal particulate trap 200gr, 300gr, 400g at engine speed between 900-1700rpm. The results of this study indicate that the lowest noise level is obtained from a 300 gr particulate trap ranging from 79.3 dB - 79.4 dB.

Abstract

Motorized vehicles are one of the most widely used means of transportation in everyday life by the community. Engine performance is supported by the presence of an engine that complements the vehicle's performance due to the engine as a lubricant in motorized vehicles. In motorized vehicles, it is often found that engine problems are quickly hot when used by drivers when traveling long distances and even when stuck in traffic. To overcome this problem, an Oil Breather System will be added to the vehicle by punching a hole on the right side of the engine and planting a nipple for the hose holder Oil Breather System. From that point on, the oil will flow quickly directly from the oil pump. The oil is then passed on the hose to the Oil Breather System. From there the oil is cooled by gusts of wind received by the Oil Breather System and proceed to the Oil Breather System hole. Therefore, the Oil Breather System was installed in motorized vehicles. With the installation of the Oil Breather System in the Cover Valve section, the Cover driven chain air heat temperature on the 2012 Yamaha Mio-J vehicle engine can be reduced by a temperature of 5 ° C. This research will continue for other types of vehicles.

Abstract

Motor bakar adalah suatu mesin konversi energi yang merubah energi thermal menjadi energi mekanik. Tetapi emisi gas buang yang dihasilkan dari proses pembakaran bahan bakaryang tidak sempurna dapat menyebabkan polusi udara, sehingga konsentrasi emisi gas buang yang dihasilkan dari proses pembakaran perlu diminimumkan. Penelitian ini dilakukan untuk mengetahui sejauh mana pengaruh variasi diameter filter active carbon terhadap konsentrasi emisi gas buang dan unjuk kerja motor bensin empat langkah pada putaran 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm dan 3000 rpm. Sedangkan diameter filter active carbon yang digunakan yaitu 20 mm, 30 mm, 40 mm, 50 mm dan 60 mm. Hasil penelitian menunjukkan bahwa pengaruh variasi diameter filter active carbon pada muffler terhadap konsentrasi emisi gas buang yaitu dapat mengurangi emisi gas CO, CO2 dan gas HC. Dimana Semakin kecil diameter filter active carbon maka konsentrasi emisi gas CO, CO2 dan gas HC yang dihasilkan akan semakin rendah. Pengaruh variasi diameter filter active carbon pada muffler terhadap torsi (T), Daya efektif (Ne), Spesifik Fuel Consumption Effective (SFCe) dan Efisiensi thermal (ηt) yaitu dimana semakin kecil diameter filter active carbon maka torsi, daya efektif dan Spesifik Fuel Consumption Effective yang dihasilkan akan semakin menurun tetapi efisiensi thermal yang dihasilkan meningkat

Abstract

Welding technology is an important process in the field of manufacturing in metal welding. SMAW welding uses electrical energy as a heat source and additional electrodes in joining metal welding. The angle of the electrode and the current strength greatly affect the welding strength. In this research, the design and analysis of variations in electrode angle and current strength in SMAW welding were carried out on tensile strength. The material used for testing is ST37 steel. The electrode angles used are 65o, 70o and 75o. The magnitude of the current used is 3 variations, namely 90 A, 95 A, and 100 A. In this research, the data processing method used is a factorial design with data from the results of tensile strength testing. In this study, the largest tensile strength test results were obtained at an electrode angle of 70o with a current strength of 100 A, getting a result of 32.668 kg/mm2, while the smallest result was obtained at an electrode angle of 65o with a current strength of 90 A, getting a result of 19.96 kg/mm2. The results of this research will be used as a reference for further research with variations in angle and current, using different test materials.
