Abstract

Implementing the use of Autodesk Inventor software in technical drawing learning for vocational learners can significantly improve their competence. By learning this software, learners can develop the skills necessary to produce accurate and detailed technical drawings. From the Inventor software training that has been carried out to students of SMK Nurul Islam and SMK Muhammadiyah 1 Gresik, students have understood and increased their knowledge of Inventor software from 30% of students who have never tried this software before. Pelathan is conducted by lectures, questions and answers, demonstrations and exercises. The results of this Inventor software training received a 50% satisfaction assessment for the speakers, facilitators, and facilities obtained. As for the material provided by 63% with a good rating scale. Suggestions from participants during the training that training like this is often held to increase the competence of SMK students in Gresik.

Abstract

Penelitian ini menganalisis sistem kompresor udara screw di PT. Pertamina Patra Niaga – Bitumen Plant Gresik dengan menggunakan metode Failure Mode and Effect Analysis (FMEA). Tujuan dari penelitian ini adalah untuk mengidentifikasi komponen-komponen kritis yang memiliki potensi kegagalan signifikan berdasarkan nilai Risk Priority Number (RPN). Hasil analisis menunjukkan bahwa komponen dengan nilai RPN tertinggi adalah dinamo (270), valve minimum pressure (192), oil filter (168), air filter (140), separator (105), dan actuator (72). Nilai RPN yang tinggi menunjukkan bahwa komponen tersebut memerlukan perhatian lebih dalam hal perawatan preventif untuk mencegah potensi kegagalan yang dapat mengganggu operasional sistem. Rekomendasi yang diberikan dalam penelitian ini meliputi penerapan perawatan berbasis waktu dan kondisi, penjadwalan perawatan rutin, pembersihan kompresor secara berkala, serta penerapan sistem monitoring otomatis untuk meningkatkan keandalan sistem secara keseluruhan.

Abstract

This study  focuses on the assembly and testing process of a Vacuum Test device as one of the Non-Destructive Testing (NDT) methods for detecting leakage in welded joints. The activities were conducted at PT. Kintomo Engineering Group, Gresik, with the objective of understanding the working principles, assembly procedures, and effectiveness of the Vacuum Test device in industrial applications. The methods applied included direct observation, participation in technical activities, and simulation analysis using Autodesk Inventor software. The test results indicate that the Vacuum Test device is capable of achieving vacuum pressures of 50–100 mbar and performs effectively in detecting defects such as porosity and micro-cracks in welded joints. Simulation results show a maximum stress of 0.613 MPa with a safety factor of 15, indicating that the device is structurally safe for repeated use. Based on these findings, the Vacuum Test method is proven to be an effective visual inspection tool for detecting leakage without causing damage to the material structure.

Abstract

Bearings are critical elements for supporting shaft rotation in industrial equipment. In the AST-MPV detergent-packaging machine at PT. X, ASB 6302-2RS bearings frequently experience jamming because of detergent-dust contamination. This study analyzed bearing service life and evaluated, as an initial comparative observation, the effect of additional grease under detergent-water exposure. The analytical stage used rotational speed, load conversion, dynamic equivalent load, and nominal bearing-life calculation with standardized N and kN units. The experimental stage compared two specimens: bearing A with manually applied Black Grease NLGI 3 LA and bearing B without additional grease. Both specimens were immersed in a 2 kg detergent and 1 L water mixture for five days, rotated at 1000 rpm for 30 min and 1500 rpm for 30 min, and measured using caliper and dial indicator. The corrected spring deflection was 0.006 m, and the calculated service life was 3479.1223 h at 1930 rpm. Additional grease reduced radius wear from 0.52 mm to 0.13 mm and outer-diameter wear from 0.10 mm to 0.03 mm. These findings suggest that scheduled grease lubrication may reduce wear in detergent-contaminated environments, although replicated testing is required.

Abstract

Rolling bearings are critical machine elements, but catalogue rating life and short-duration workshop observations must be interpreted separately. This study calculated the ISO 281 basic rating life of a Koyo/JTEKT 6302-2RS deep-groove ball bearing (JTEKT Corp., Kariya, Aichi Japan) and conducted a preliminary comparison of three lubrication treatments. The calculation used the current JTEKT basic dynamic load rating C = 14.3 kN, an equivalent radial load P = 98.1 N, and the ball-bearing exponent p = 3. Three bearings were used (n = 1 per treatment). Their seals were removed, the factory grease was cleaned out, and the specimens were either left without reapplied grease or manually filled with Cobra® Chassis Grease Green No. 3 or Deltalube® 056 General Purpose Grease EP 2; the applied grease mass was not recorded. Each specimen was tested sequentially for 30 min at 1000 rpm and 30 min at 1500 rpm under the same radial load. The corrected basic rating life was 3.097 × 10¹² revolutions, equivalent to 5.162 × 10⁷ h at 1000 rpm and 3.442 × 10⁷ h at 1500 rpm. These very large values reflect an idealized rating-life calculation at a load far below the catalogue capacity and are not an experimentally validated service life. After cumulative testing, the recorded outer-diameter changes were 0.05 mm for the grease-free control, 0.03 mm for Cobra® grease, and 0.01 mm for Deltalube® grease; these changes are comparable with the stated caliper accuracy. At 1500 rpm, the outer-ring radial runout values were 0.30, 0.16, and 0.15 mm, respectively, while the inner-ring values were 0.09, 0.05, and 0.04 mm. Deltalube® grease produced the lowest observed dimensional change and runout under the present conditions, but the unreplicated, sequential test does not support statistical or long-term reliability claims.
