Abstract

This study addressed a critical safety and efficiency challenge in the maintenance of air fan cooling systems at company XYZ LNG, where technicians traditionally relied on unsafe manual methods, using bare hands and a wooden block to stop rotating pulleys. These practices, observed over a decade of operations, were identified as a leading cause of near-miss incidents, exposing operators to crush injuries, entanglement, and amputations. Motivated by the need for a safer, engineered solution, this research designed, fabricated, and implemented a specialized pulley locking tool. Developed through a structured engineering design process, the tool prevents direct human contact with moving components while aligning with modern safety management principles and human factors engineering. Field trials demonstrated a reduction in braking time from 20–30 minutes to only 4 minutes, along with significant ergonomic and psychological benefits reported by operators. The tool not only improved efficiency but also strengthened confidence in maintenance procedures. This work represents a practical intervention that transforms safety theory into application, providing a replicable model for other LNG facilities and industries with rotating equipment. The results highlight how engineered tools can simultaneously mitigate risks and improve productivity in high-risk environments.

Abstract

Welding technology has an integral role in the manufacturing technology domain. To create high-quality structures requires technology that allows joining metals. It is in this phase that welding technology comes into play. TIG (Tungsten Inert Gas) welding is a form of tungsten gas arc welding, where the electrode acts as an arc supplier that does not melt during the welding process. The Gas Tungsten Acr Welding technique is generally used more on light metals such as magnesium, aluminum, and stainless steel, and other types of metal. This type 201 carbon steel has several mechanical characteristics, including a tensile strength of 580 Mpa, an elastic limit (yield strength) of 198 Mpa, an elongation rate of 50%, and a hardness of 87 HRBI. The aim of this research is to determine the tensile strength and microstructure of TIG (Tungsten Inert Gas) welding results with 45 degrees of V, U and J seams. This research was carried out with several flat 2D test models of 45 degrees of V, U and J seams with current. 110 - 120. This research was conducted at the Banyuwangi Job Training Center, in the Materials Laboratory for Mechanical Engineering at Sebelas Maret University, Surakarta and at the Mechanical Engineering Laboratory at Jember State University. In this research, the results of changes in tensile strength were quite significant. The lowest tensile strength value is found in the J weld seam with an average value of 394.4 MPA. Meanwhile, the highest tensile strength value is found in the V weld seam with an average value of 531.1 MPA. The results of the microstructure for J seam have the largest phase grains and V seam forms the smallest phase grains compared to the others. Kampuh V has quite a large number of grains because they are relatively small and dense.

Abstract

This research aims to determine the effect of variations in welding currents of 90A, 100A, and 110A on SMAW bases on the material in the tensile, hardness, and microstructure tests. This research uses ST37 low carbon steel and uses E6013 electrodes with a diameter of 3.2 mm, followed by making specimens for testing. After that, the welding process is carried out and then testing continues. In the test, the following results were obtained: The strength value of the welded material with tensile testing was obtained with the highest results at a current variation of 110A with Yp 27.33 Mpa, Max 36.47 Mpa, Break 31.08 Mpa. Because the highest pearlite microstructure value is obtained in the 110A variation. And the lowest value occurred in the welded material of variation 90A with Yp 25.48 Mpa, Max 26.86 Mpa, Break 12.33 Mpa. Because the lowest pearlite microstructure value is obtained in the 90A variation. while the comparison of the level of hardness in ST 37 carbon steel with varying welding currents ranging from 90A, 100A, and 110A has an average hardness value of 168 VHN for welding with a current of 90A for welding with a current of 100A the average hardness value is 177 VHN and finally in welding current 110A the average hardness value is 191 VHN. The hardness level of the ST 37 carbon steel specimen was the highest at a welding current of 110A, with a tensile strength test result of 36.47 MPa. And from the results of observing photos of the microstructure using the point count method, the highest percentage of pearlite was in the welding material variation 110A so the tensile strength value was higher.

Abstract

Kinerja sistem pelumasan pada mesin industri sangat dipengaruhi oleh kualitas oli yang digunakan. Kontaminasi berupa partikel logam, serpihan karbon, dan kotoran mikroskopis dapat menyebabkan penurunan efisiensi pelumasan, peningkatan temperatur kerja, hingga percepatan keausan komponen. Penelitian ini merancang dan menganalisis alat filtrasi oli berbasis filter mekanis yang diterapkan pada tangki oli skala industri guna meningkatkan kebersihan oli selama proses operasi. Sistem filtrasi dirancang dengan konsep sirkulasi kontinu, di mana oli dialirkan dari tangki menuju media filter berpori 5mikron menggunakan pompa low-pressure dan dikembalikan kembali ke dalam tangki. Pengujian dilakukan pada oli terkontaminasi partikel padat buatan dengan ukuran <= 50 mikron. Hasil menunjukkan bahwa alat filtrasi mampu menurunkan jumlah partikel hingga 80–90% setelah periode filtrasi 45–90 menit, serta meningkatkan kejernihan oli secara signifikan. Dengan demikian, alat filtrasi mekanis ini terbukti efektif dalam memperpanjang umur pakai oli, meminimalkan downtime mesin, dan mengurangi biaya perawatan pada sistem pelumasan industri.
