IDENTIFIKASI DAN PENILAIAN RISIKO KERJA MENGGUNAKAN METODE SWIFT PADA BENGKEL OTOMOTIF SKALA MENENGAH STUDI KASUS: CV XYZ

Fitra Fitra — 2025-11-30

Workplace accidents remain a significant concern in small and medium enterprises (SMEs), particularly in sectors with high physical labor intensity such as automotive repair workshops. This study aims to identify and assess occupational hazards in CV XYZ, a medium-sized workshop specializing in engine and body repair, using the Structured What-If Technique (SWIFT). Through field observations, interviews, and questionnaires, data were collected on potential hazards during major work processes. The SWIFT method was applied to examine risks based on frequency and severity, culminating in a Risk Rating Number (RRN) for each hazard. The study found 23 hazards in engine repair activities and 20 in body repair, with six identified as top-priority risks (RRN = 10). These included crush injuries, lacerations, and unsafe working postures. Recommendations were proposed to reduce risk levels, including the use of ergonomic tools, implementation of personal protective equipment (PPE), safety training, and workplace layout improvements. The findings underscore the effectiveness of the SWIFT method in fostering participatory risk assessment and enhancing safety awareness in SMEs. This approach provides a practical model for similar workshops aiming to improve their occupational safety and health (OSH) performance systematically.

Rizki Prakasa Hasibuan — 2025-11-30

The participation of Micro, Small, and Medium Enterprises (MSMEs) in Indonesia’s industrial supply chains remains critically low, accounting for only 6.3% of the total 65.5 million MSMEs. This condition highlights the urgency of implementing strategic measures to enhance their integration into the national industrial ecosystem. This study aims to examine the existing conditions of MSME supply chains and to develop an efficient supply chain management (SCM) model aligned with their operational capacities. The research was conducted in two phases: (1) an assessment of current supply chain practices through a survey of 25 MSMEs in the food and handicraft sectors in Batam City, and (2) the design and simulation of an SCM model involving three partner MSMEs. The findings reveal that most MSMEs lack stable supplier networks, do not employ systematic production scheduling, and have yet to adopt information technology in their operations. To address these challenges, a Hybrid Collaborative SCM (HCSM) model comprising five core components was developed. Simulation results indicate significant improvements in delivery lead times, transportation costs, production cycle times, and a reduction in stock-out frequencies, thereby demonstrating the model’s potential to enhance MSME supply chain performance

Siti Nur Maulidina — 2025-11-30

The capture fisheries sector plays a crucial role in supporting food security and the Indonesian economy, particularly in the Riau Islands region. Traditional fishermen hold a pivotal position in the post-harvest chain of capture fisheries. However, traditional fishermen still face various challenges, one of which relates to non-ergonomic working conditions when storing fish catches. Currently, traditional fishermen use makeshift fish storage boxes without considering ergonomic and anthropometric aspects. Non-ergonomic storage boxes can cause health problems such as back pain, muscle injuries, and excessive fatigue among fishermen. This condition can negatively impact fishermen's productivity and quality of life. This research is essential to develop an ergonomic fish storage box design that aligns with the anthropometric characteristics of traditional fishermen. With ergonomic equipment, it is expected to enhance fishermen's comfort and occupational safety while minimizing health risks associated with work activities. Furthermore, ergonomic equipment can also improve fishermen's productivity and work efficiency in storing fish catches. The aim of this research is to design ergonomic equipment for traditional fishermen that corresponds to anthropometric characteristics, thereby facilitating and enhancing comfort and occupational safety for traditional fishermen. This research will employ an anthropometric approach as the foundation for designing ergonomic equipment for traditional fishermen. Data collection will involve anthropometric measurements of traditional fishermen using a sample of fishermen as respondents. Body dimension measurements will be conducted to obtain static and dynamic anthropometric data. Based on the anthropometric data, a prototype of an ergonomic fish storage device will be developed.

ANALISIS PENENTUAN JUMLAH PRODUKSI STANDAR SERTA TENAGA KERJA YANG OPTIMAL PADA PRODUKSI KEMBANG GOYANG DI UMKM JATINEGARA

Masri Pradipto — 2025-11-30

UMKM Kembang Goyang is one of the UMKM located in the Jatinegara area, East Jakarta. This UMKM has a flagship product in the form of kembang goyang cake. The high demand for kembang goyang cake orders, especially before Eid al-Fitr (Lebaran), with only 2 workers, makes this UMKM overwhelmed in fulfilling its production, resulting in this UMKM losing orders up to 100 packs. This study aims to calculate the processing time of each work station, standard output and the optimal number of workers needed. The method used in this study is a stopwatch time study. The stopwatch time study method is a direct measurement to obtain actual time or cycle time by considering the operator's work tempo and allowance, so that standard work time is obtained. The results show that kembang goyang cake produced from 1 kg of flour can produce 228 cakes. The standard time for kneading is 30 minutes per dough container. The standard heating time is 28 minutes per 2 liters of cooking oil. The standard time for frying until the dough is finished is 3 hours. Safety stock and defective products are set at 8 cakes, so there are 220 cakes ready to be packed at the packaging station. The standard time for packing 220 cakes into 10 packages is 30 minutes. The total time needed to make kembang goyang cakes from 1 kg of flour is 4 hours and 15 minutes. The number of workers needed at each work station is 1 person, but because this work is continuous, 1 person can work continuously from the kneading station, heating the oil, frying to packaging. If the order before Lebaran reaches 100 packages, then the number of workers needed is 10 people at each work station.

ANALISIS WORK-RELATED MUSCULOSKELETAL DISORDERS (WMSDS) PADA OPERATOR MANUFAKTUR ELEKTRONIK DENGAN PENDEKATAN NORDIC BODY MAP (NBM) & QUICK EXPOSURE CHECKLIST (QEC)

Nurha Vina Jingga — 2025-11-30

This study comprehensively evaluates the risk of Work-Related Musculoskeletal Disorders (WMSDs) among production operators at PT EMS, a company engaged in electronics manufacturing. Utilizing a mixed-methods ergonomic approach, the research employed the Nordic Body Map (NBM) to measure operators' subjective complaint levels and the Quick Exposure Checklist (QEC) to assess objective posture-related exposure risks. Analysis of NBM data revealed that the Printing station exhibited the lowest average complaint levels (5.6 total average complaints per operator), indicating better ergonomic conditions. Conversely, Wave Solder and Cutting Point operators reported the highest average total complaints (11.9 and 11.6, respectively), with the Wave Solder station registering the highest proportion of "Severe Pain" cases. The QEC analysis, which focused on the worst-case operator exposure, identified the Wave Solder station as the most critical, yielding the highest Exposure Score of 88% (Action Level 4), followed closely by Printing (78%) and Cutting Point (74%). The body parts most susceptible to injury across these high-risk stations were the Back (QEC score 44), Wrist (40), and Shoulder/Arm (36). The findings confirm that prolonged static posture, repetitive movements, and manual material handling are primary contributors to WMSDs prevalence. Immediate interventions are highly recommended, specifically the provision of push assistance tools, elbow supports, and footrests at the workstation to mitigate exposure risk and enhance occupational health.
