Abstract

This community service activity aims to introduce the laboratory environment and facilities of the Mechanical Engineering Study Program at Institut Teknologi Sumatera (ITERA) to students of SMKN 1 Raman Utara, East Lampung. The activity was conducted in the form of a campus visit involving 62 12th-grade students from the Light Vehicle Engineering Department. The agenda included a presentation on higher education opportunities, interactive discussions, a Q&A session, and a direct tour of ITERA’s Mechanical Engineering laboratories, including the Materials Engineering, Energy Conversion, Fabrication, Manufacturing, Internal Combustion Engines, and Foundry laboratories. This activity was designed to inspire students to pursue higher education and broaden their understanding of engineering fields. The outcome showed a high level of enthusiasm among the students and successfully achieved the goal of introducing campus life and technological exposure. This initiative is expected to serve as an initial step in strengthening synergy between vocational high schools and higher education institutions.

Abstract

The effects of global warming are very impactful in everyday life, one of which makes the air feel hot, a cooling machine is needed to be able to reduce hot air in a room. Cooling machines have become an important necessity in everyday life. The cooling machine can be maximally utilized if the heat load above it must be appropriate or below. This research was conducted to analyze the cooling load in the public lecture room 1 of the Sumatra Institute of Technology GK-104. The data required in this study are the length of the room, the width of the room, the amount of internal heat of the room, the maximum number of people in the room, and the cooling capacity of the air conditioner. For the calculation of cooling load analysis is divided into 4 parts namely occupant load, equipment load, lighting load, and transmission load. After the analysis, the value of each is obtained 2,656.68 W, 450.09 W, 3,930.62 W, 2,238.71 W. The total cooling load of a room is 9,276.114 W. For the capacity of 2 air conditioners GK-104 room is 10,040 W. It can be concluded that the cooling load of the room is still far below the cooling capacity of the air conditioner and the room can cool according to the desired temperature.

Abstract

Bearings are important components in industry that function to reduce friction between moving parts for smoother and more efficient movement. However, friction that occurs can cause wear on the bearing surface. This study aims to analyze the wear volume, wear width, and wear rate of ASTM 440C steel material with variations of SAE 10W-30, SAE 10W-40, and SAE 140 lubricants at rotational speeds of 180 rpm, 270 rpm, and 310 rpm. Testing was carried out using a tribometer. ball-on-disc with a constant time of 10 minutes. The test results showed that the lowest wear width was obtained in SAE 10W-40 lubricant of 259.806 µm at 180 rpm, while the highest value of 417.894 µm also occurred in SAE 10W-40 at 270 rpm. The lowest wear volume was recorded in SAE 10W-40 of 0.0225 mm³ at 180 rpm, while the highest was 0.0942 mm³ at 270 rpm with the same lubricant. For the wear rate, the lowest value of 0.50 × 10?? g/mm²·s was found in SAE 140 lubricant at 180 rpm, while the highest was 1.58 × 10?? g/mm²·s occurred in SAE 10W-40 at 270 rpm. Overall, SAE 10W-40 lubricants are more suitable for use at low revs, while SAE 140 lubricants are recommended for high revs due to their greater viscosity and resistance to wear.

Abstract

Program Studi Teknik Mesin ITERA mengembangkan disiplin berbasis cabang ilmu teknik mesin yang didefinisikan sebagai ilmu teknik yang mempelajari perancangan, produksi/pembuatan dan operasi mesin. Kunjungan siswa-siswi SMKN 1 Gadingerjo ke kampus merupakan salah satu upaya yang penting dalam memperkenalkan dan mempersiapkan mereka untuk pengalaman pendidikan tinggi. Dalam beberapa kasus, kunjungan siswa ke kampus juga dapat menjadi bagian dari program orientasi atau rekrutmen mahasiswa baru. Hal ini memungkinkan siswa untuk memperoleh pemahaman yang lebih baik tentang persyaratan pendaftaran, proses seleksi, dan tata cara mengajukan aplikasi. Kunjungan dimulai dari Penerimaan Siswa Siswi SMKN1 Gadingrejo di Gedung Kuliah umum yang dilanjutkan dengan sesi diskusi. Selanjutnya kunjungan Laboratorium teknik mesin sebagai sarana pembelajaran kepada para siswa. Dengan demikian, kesimpulan dari sosialisasi program studi Teknik Mesin kepada SMKN1 Gadingrejo adalah bahwa kegiatan ini memiliki dampak positif dalam memberikan informasi, kesempatan, dan motivasi bagi siswa untuk mempertimbangkan dan memilih pendidikan tinggi di bidang teknik mesin sebagai langkah awal menuju karir yang sukses dan memuaskan.
