Abstract

This study identifies and evaluates occupational health and safety risks faced by workers in vehicle washing operations in Mataram, Nusa Tenggara Barat, focusing on motorcycle and car wash services. Through observational studies conducted on April 6, 2025, key hazards were identified, including musculoskeletal disorders (MSDs) from non-ergonomic postures, chemical exposure from soap, slipping on wet floors, and noise from compressors. The Rapid Entire Body Assessment (REBA) method revealed high ergonomic risks, with REBA scores of 10 for both motorcycle and car wash workers, indicating a significant risk of MSDs due to prolonged bending and repetitive motions. Bowtie Analysis further mapped causes, consequences, and control measures, emphasizing non-ergonomic postures and chemical hazards as primary concerns. Preventive strategies, such as ergonomic training, long-handled tools, and personal protective equipment (PPE), were proposed to mitigate risks. The findings align with global studies reporting high MSD prevalence among sanitation workers, underscoring the need for ergonomic interventions and safety protocols. This study contributes to the literature by offering tailored risk mitigation strategies for the vehicle washing industry, advocating for enhanced worker safety, improved productivity, and reduced occupational health risks through comprehensive risk management and ergonomic solutions..

Abstract

This study aims to analyze the efficiency of bread production processes at the MSME Tina Bakery using the stopwatch time study method. The production process was mapped with an Operation Process Chart (OPC) and a Worker–Machine Chart to identify workflow and the simultaneous involvement of operators and equipment. Work‐time data were collected through direct observation and subsequently analyzed to determine cycle time, normal time, and standard time. The findings indicate that one production cycle requires an observed time of 22,029 seconds, equivalent to approximately 6 hours and 7 minutes. Assuming a performance rating of 100% and a 20% allowance, the standard time is 26,434.8 seconds, or roughly 7 hours and 34 minutes. Proofing is the longest stage, while several manual activities—such as dough shaping—also consume substantial time. The work‐study charts reveal an imbalance between operator and machine times, indicating considerable idle time. Based on these results, this study recommends rescheduling production, productively utilizing waiting periods, and adopting mechanical aids for labor-intensive tasks to improve efficiency and productivity. The study contributes to the development of measurable work standards in the context of food-sector MSMEs
