Abstract

Penelitian ini menganalisis pengaruh variasi jarak penyemprotan terhadap ketebalan lapisan cat pada body kendaraan di dalam spray booth. Metode yang digunakan adalah eksperimen kuantitatif dengan pendekatan quasi-experimental deskriptif pada pelat baja yang dicat Penta Super Gloss NC Metallic. Spray gun gravitasi dioperasikan pada tekanan konstan 2,8 bar dengan jarak penyemprotan 10, 15, 20, 25, dan 30 cm. Setelah pengeringan oven pada 60 °C selama 20 menit, ketebalan lapisan cat warna diukur menggunakan coating thickness gauge pada tiga titik untuk setiap jarak. Hasil menunjukkan tren penurunan ketebalan rata-rata dari 64,33 µm pada jarak 10 cm menjadi 47,20-48,50 µm pada jarak 25-30 cm, yang paling mendekati standar industri sekitar 50 µm dan menghasilkan permukaan yang lebih halus serta merata. Temuan ini menegaskan pentingnya pengaturan jarak penyemprotan di dalam spray booth sebagai parameter utama untuk mengendalikan ketebalan lapisan cat. This study investigates the effect of spraying distance using a spray gun on coating thickness on vehicle body panels inside a spray booth. A quantitative quasi-experimental method was applied on steel plates coated with Penta Super Gloss NC Metallic paint. A gravity spray gun was operated at a constant pressure of 2.8 bar with spraying distances of 10, 15, 20, 25, and 30 cm. After oven drying at 60 °C for 20 min, the coating thickness of the color layer was measured using a coating thickness gauge at three points for each distance. The results show a decreasing trend in average coating thickness from 64.33 µm at 10 cm to 47.20–48.50 µm at 25–30 cm, which is closest to the 50 µm automotive standard and produces smoother, more uniform surfaces on the vehicle body. These findings highlight spraying distance as a key controllable parameter for achieving target coating thickness in spray booth applications.

Abstract

This training activity was conducted for a group of farmers in Saureinu Village, Mentawai Islands Regency. Based on the team's observation data, we found that many farmers in Saureinu Village still do not understand how to maintain agricultural machinery. As a result, many agricultural machines in Saureinu Village are damaged and cannot be used, thereby reducing farmer productivity. Through this activity, training on agricultural machinery maintenance was provided to the Saureinu village farmer group using the Practical Demonstration method. The Practical Demonstration method was considered appropriate for participants who had diverse backgrounds and no prior understanding of machinery. Based on the team's assessment at the beginning and end of the activity, there was an increase in the participants' knowledge and competence related to the material provided. In the theory session, participants' knowledge increased by 52%, and in the practice session, participants' competence increased by 40%. Participants' mastery of each sub-topic increased by 35-40%. Based on the conversion of scores to assessment categories, this activity was able to improve participants' competencies from poor to good. This improvement is expected to enable the Saureinu Village farmer group to maintain the agricultural machinery they use and maintain stable agricultural productivity.

Abstract

Pekerjaan mekanik kendaraan niaga melibatkan postur dan aktivitas fisik yang dapat disertai keluhan muskuloskeletal. Penelitian ini bertujuan memetakan lokasi dan intensitas keluhan pada tiga mekanik Bengkel X menggunakan Nordic Body Map (NBM). Penelitian kuantitatif deskriptif dengan pendekatan studi kasus menggunakan NBM pada 28 bagian tubuh berskala 1–4 dan pertanyaan jawaban jamak mengenai aktivitas yang dipersepsikan berkaitan dengan keluhan. Enam bagian tubuh memenuhi kriteria operasional dominan, yaitu leher bagian atas, leher bagian bawah, bahu kiri, bahu kanan, punggung, dan pinggang. Punggung menunjukkan pola paling konsisten dengan skor 3 pada seluruh mekanik. Dari 84 penilaian bagian tubuh, 45,2% termasuk tidak sakit, 40,5% agak sakit, dan 14,3% sakit. Temuan bersifat spesifik pada studi kasus ini dan dapat digunakan sebagai skrining awal untuk memprioritaskan asesmen ergonomi objektif di Bengkel X. Commercial vehicle mechanics perform physically demanding tasks that may be associated with musculoskeletal complaints. This study aimed to identify the location and intensity of musculoskeletal complaints among three mechanics at Workshop X using the Nordic Body Map (NBM). A descriptive quantitative case-study design was applied. The NBM assessed 28 body regions on a 1–4 scale, supplemented by multiple-response questions on activities perceived to trigger complaints. Six body regions met the dominant-complaint criterion: upper neck, lower neck, left shoulder, right shoulder, back, and lower back. The back showed the most consistent complaint intensity, with all mechanics reporting a score of 3. Of 84 body-region ratings, 45.2% were classified as no pain, 40.5% as mild pain, and 14.3% as pain. These findings provide preliminary screening information for prioritizing objective ergonomic assessment at Workshop X and should not be interpreted as population prevalence or causal evidence.

Abstract

Abstract: Cold spray is a rapidly advancing solid-state deposition technology for coating and repairing metal-alloy components, valued for minimizing oxidation and phase transformation compared to conventional thermal spray. This study analyzes research trends on mechanical properties, wear resistance, corrosion, and fatigue/fracture mechanisms of cold-sprayed metal-alloy coatings from 2020-2025 publications, using a Systematic Literature Review (SLR) guided by PRISMA 2020. Literature searching via Publish or Perish on the Scopus database yielded 200 initial records; after title screening and eligibility assessment, 18 articles met the inclusion criteria for synthesis. Results show: (1) research concentrated in 2020 (9 of 18 articles, 50.0%) with consistently high citation impact across the period; (2) research focus was dominated by wear/tribological behavior studies (33.3%), followed by microstructure and process modeling and general application reviews (16.7% each); (3) hard reinforcing phases (WC, TiC, CoCr) consistently improved wear resistance, while residual porosity and inter-particle bonding quality remained dominant factors affecting fatigue, fracture, and corrosion performance. VOSViewer bibliometric analysis revealed close linkage among eight key terms within one coherent thematic cluster. This study concludes that optimizing process parameters to minimize porosity and maximize inter-particle bonding is the most crucial direction for future structural applications of cold spray coatings/repairs on metal alloys.Keywords: Cold Spray; Fatigue And Fracture Mechanism; Wear Resistance; Corrosion; Metal Alloy.

Abstract

Stunting awareness campaigns conducted through the Community Service Program (Kuliah Kerja Nyata/KKN) serve as a strategic initiative to raise public awareness about the importance of balanced nutrition for child growth and development, considering that stunting resulting from chronic nutritional deficiencies can have long-term effects on children's physical and cognitive development. In this activity, students acted as agents of change by educating the community on healthy eating patterns, the importance of exclusive breastfeeding, and routine child growth monitoring. The outreach methods included counseling sessions, interactive discussions, demonstrations of nutritious food preparation, and social media campaigns to reach a broader audience. Challenges encountered included low public understanding and limited access to nutritious food. However, through participatory approaches and collaboration with healthcare professionals and local government, the activity successfully increased community awareness of the dangers of stunting and preventive measures. The implementation results showed a significant improvement in understanding the importance of family nutrition, with the potential to contribute to a reduction in stunting rates in the target area. This initiative not only produced short-term impacts but also fostered long-term awareness that supports healthy lifestyles within families. Therefore, stunting-focused KKN programs should continue to be developed and expanded to promote the emergence of a healthy and stunting-free generation.
