Abstract

Untuk menjadi tenaga kerja siap pakai dan terampil, lulusan SMK dituntut memiliki kompetensi yang memadai. Data BPS Agustus 2021 menyatakan bahwa 11,38% jumlah pengangguran berasal dari lulusan SMK. Kenyataan ini membuktikan bahwa kompetensi lulusan SMK belum sesuai dengan harapan dunia kerja. Masalah ini timbul karena belum terciptanya keselarasan kompetensi lulusan SMK dengan kebutuhan dunia kerja. Keselarasan ini dipengaruhi oleh sumber daya, sarana dan prasarana sekolah. Jurusan TBSM SMKN 1 Sungai Aur Kabupaten Pasaman Barat Provinsi Sumatera Barat merupakan jurusan yang baru berdiri sehingga sarana dan prasarana yang dimiliki juga masih sedikit. Hasil observasi menemukan bahwa jurusan ini belum memiliki media pembelajaran simulator engine cutting sepeda motor programmed fuel injection, sehingga menyebabkan rendahnya kompetensi siswa. Salah satu kompetensi yang harus dikuasai siswa jurusan TBSM dan sesuai dengan tuntutan dunia kerja saat ini adalah teknologi sepeda motor programmed fuel injection. Upaya yang dilakukan melalui kegiatan pengabdian kepada masyarakat untuk meningkatkan kompetensi siswa jurusan TBSM adalah rancang bangun simulator engine cutting dan pelatihan teknologi programmed fuel injection sepeda motor. Hasil evaluasi awal dan akhir kegiatan menunjukkan bahwa terdapat peningkatan kompetensi siswa TBSM SMKN 1 Sungai Aur tentang teknologi programmed fuel injection sepeda motor sebesar 60,71%.

Abstract

Occupational safety is a critical concern in automotive workshop environments due to the high-risk nature of tasks such as engine repair, welding, and electrical diagnostics. This study investigates automotive workshop risks at the Mitsubishi DIPO Workshop in Bukittinggi by identifying hazards, assessing risk levels, and formulating workplace accident prevention strategies. The HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method was applied to evaluate 28 potential hazards, two of which were classified as extreme risks. Further analysis of these risks was conducted using the Fishbone Diagram to identify root causes across six contributing factors: human, machine, material, method, environment, and management. Based on these findings, targeted risk control measures were developed following the hierarchy of control, including engineering interventions, administrative policies, and personal protective equipment. This research demonstrates how integrated methods such as HIRARC and Fishbone Diagram can support comprehensive occupational safety planning and risk mitigation in automotive workshops.

Abstract

This study investigates the mechanical performance of coconut coir fiber-reinforced composites with volume fractions of 30% and 40%, fabricated using the Manual Hand Lay-Up method. Specimens were tested under three-point bending following ASTM D790-03 to evaluate flexural strength. Results show that composites with a 30% fiber volume exhibit superior bending strength and stiffness compared to those with 40%, indicating a more optimal fiber–matrix ratio. The reduction in performance at higher fiber content is attributed to uneven resin distribution and inadequate fiber impregnation. These findings highlight the potential of coconut coir as a sustainable reinforcement material and emphasize the importance of optimizing fiber volume and manufacturing methods. The study recommends the use of alternative fabrication techniques, such as vacuum infusion, to improve resin homogeneity and mechanical reliability, particularly for structural and lightweight composite applications.

Abstract

This study presents a thermo-structural finite element analysis of a single-cylinder diesel piston using ANSYS, comparing three aluminum alloys: Al2618-T61, Al4032-T6, and Al6061-T6. A coupled simulation approach was applied, where steady-state thermal results were imported into static structural analysis. Realistic boundary conditions, including applied combustion pressure, symmetry constraints, and cylindrical pin supports, were implemented based on Yanmar TF55 engine geometry. Results indicate that Al6061-T6 experienced the highest deformation and stress, nearing its yield limit at elevated temperatures. In contrast, Al2618-T61 and Al4032-T6 maintained structural integrity, with lower stress and elastic deformation within safe limits. Al4032 demonstrated superior dimensional stability, while Al2618 exhibited better strength under thermal load. These findings validate the importance of coupled thermal-structural analysis and material selection in piston design. The proposed framework offers reliable guidance for developing more durable, thermally resilient pistons for modern diesel engines.
