Abstract

Proyek pengabdian kepada masyarakat ini bertujuan mengatasi tantangan efisiensi produksi di sektor industri kecil dan menengah dengan mengeksplorasi transisi dari penggunaan CNC ke proses blanking. Fokus utama inisiatif ini adalah meningkatkan efektivitas biaya dan waktu produksi melalui penerapan teknologi blanking yang lebih efisien. Metodologi yang digunakan adalah Participatory Action Research (PAR), yang mengedepankan kolaborasi sinergis antara tim Universitas Buana Perjuangan (UBP) Karawang dan tim PT Gama Satya Engineering. Tahapan kegiatan meliputi identifikasi masalah, pengembangan solusi, hingga implementasi perubahan yang diperlukan di lapangan. Hasil menunjukkan bahwa penerapan proses blanking dengan mesin 40-ton berhasil menekan biaya produksi per komponen menjadi Rp 2.061,14, menghasilkan penghematan hingga 95,71% dibandingkan dengan proses CNC. Sementara itu, penggunaan mesin 80-ton mencatatkan biaya produksi sebesar Rp 2.200,03 per komponen dengan tingkat efisiensi 95,42%. Dari sisi waktu, proses blanking hanya memerlukan 0,0139 jam (sekitar 0,834 menit) per komponen, jauh lebih cepat dibandingkan proses CNC yang memakan waktu hingga 12 menit per unit. Temuan ini tidak hanya menunjukkan potensi signifikan dalam penghematan biaya dan waktu, tetapi juga memperkuat hubungan antara akademisi dan industri. Selain itu, hasil penelitian ini memberikan panduan praktis yang dapat diterapkan secara berkelanjutan di sektor industri kecil dan menengah, sekaligus memberikan dampak positif bagi mitra industri.

Abstract

Musculoskeletal disorders (MSDs), known in Indonesia as Gangguan Otot Tulang-Rangka Akibat Kerja (GOTRAK) are one of the most common ergonomic problems in the workplace, caused by poor posture, repetitive movements, and long working hours. These conditions have a negative impact on employee health and productivity and increase healthcare costs for companies. This study aims to analyze the potential for GOTRAK complaints among workers in the box packaging process in the food seasoning industry, in accordance with Indonesian National Standard (SNI) 9011:2021. This study was conducted using a quantitative approach with a Musculoskeletal Disorder Questionnaire to assess MSD complaints. Data were collected through field observation, questionnaire completion, and work posture analysis using the methods outlined in SNI 9011:2021. The research variables included work posture, work duration, and physical strain of the workers. The results of the worker interviews regarding body part complaints showed a high risk level with risk scores of 19 and 20. The most common parts of the body to experience pain were the shoulders, upper back, lower back, and hips. The results of the ergonomic assessment of the upper body in carton packing work gave a score of 38, indicating hazardous conditions that require immediate improvement. In addition, the results of the analysis were used to develop ergonomic-based improvement recommendations to increase safety and comfort in the workplace. It is hoped that this study will provide companies with guidance on how to reduce ergonomic risks in the workplace, improve workers' wellbeing and support the development of a more sustainable industry.

Abstract

A reliable safety climate model is essential for evaluating safety behavior and predicting risks such as accidents or injuries, yet no research has specifically addressed the safety climate in the paper industry, either globally or in Indonesia. Recognized as high-risk due to its reliance on large machinery and hazardous chemicals, the paper industry has been understudied in this context. This research addresses the gap by developing a safety climate model tailored to the Indonesian paper industry, following a rigorous methodology that included a literature review, model design, validation processes, and Goodness-of-Fit testing. The study identified nine dimensions and 36 initial indicators, with strong content validity confirmed through Aiken’s V index, and refined through a survey of 313 employees—including managers, supervisors, and operators—at a paper factory in West Java, Indonesia. Confirmatory factor analysis (CFA) led to the final model, comprising nine dimensions and 32 validated indicators, achieving excellent fit across key criteria. These dimensions include management commitment, safety environment, safety communication, safety involvement, safety rules and procedures, safety training, safety competence, work pressure, and local wisdom. The validated model offers valuable insights into safety practices, providing a practical framework for improving safety performance in the Indonesian paper industry. By fostering a proactive safety culture and addressing sector-specific risks, this model has the potential to significantly reduce workplace accidents and improve overall safety performance, marking an important advancement in industry-specific safety research.

Abstract

Spring-back and spring-go are critical elastic recovery phenomena in sheet metal forming that affect the angular precision of bent components. This study investigates the influence of punch angle, die opening, and punch speed on these behaviors during the Vee-bending process of SCGA340BHX high-strength galvanized steel. A Taguchi design of experiments with an L8 orthogonal array was applied, and spring-back angles were measured and analyzed using the “smaller-is-better” signal-to-noise (S/N) ratio criterion. The results reveal that punch angle is the most influential parameter governing spring-back and spring-go tendencies, followed by die opening and punch speed. A punch angle of 50° and a die opening of 35 mm produced the highest average spring-back (3.03°), while spring-go behavior was observed primarily at higher punch speeds (35–40 mm/min). The study further confirmed the inverse relationship between bending force and spring-back, with lower forming forces correlating to greater elastic recovery. These findings provide a comprehensive understanding of the interdependence between geometric and kinematic factors in elastic recovery phenomena, offering quantitative insights for optimizing Vee-bending operations involving thin, high-strength steel.
