Abstract

This study aims to determine and analyze body parts that experience musculoskeletal disorders (MSDs) and muscles that experience fatigue in guitar-making workers. The method used is the Nordic Body Map (NBM) to determine MSDs complaints, including complaints of pain in 28 parts of the worker's body, and the Muscle Fatigue Analysis (MFA) method to determine muscle fatigue that occurs in each part of the body by determining the level of effort, duration of work, and frequency of work movements. The results of research using NBM were 2 workers with high risk, 3 workers with medium risk, and 7 workers with low risk. The results of the MFA method were that 3 workers experienced muscle fatigue in the very high category with priority in the neck, back, shoulders, right arm, wrist and feet. Efforts to minimize the risk of MSDs by redesigning work facilities using SolidWorks software and reducing the risk of muscle fatigue by improving work facilities, improving the layout of the production floor, and encouraging workers to stretch their muscles and exercise regularly.

Abstract

The production process of acoustic guitars in Indonesia involves 4 workstations and 17 distinct activities. Due to the nature of the work—8-hour shifts in seated positions with frequent bending, squatting, and repetitive movements—workers are at risk of musculoskeletal disorders (MSDs), particularly in the neck, shoulders, back, arms, and wrists. This study aimed to identify and analyze body posture conditions using the Nordic Body Map (NBM) and Muscle Fatigue Analysis (MFA) methods. The NBM method was used to record pain complaints across various body parts, while the MFA assessed muscle fatigue by considering the level of effort, work duration, and movement frequency. Results from the NBM showed that among the workers, 2 were at high risk, 3 at medium risk, and 7 at low risk for MSDs. The MFA further identified 3 workers with very high to high-priority fatigue concerns, specifically affecting the neck, back, shoulders, right arm, wrist, and legs. To address these issues, the study recommended redesigning work facilities and layouts using the SolidWorks application, along with implementing regular muscle stretching and exercise routines to minimize the risk of MSDs and improve worker well-being.
