Abstract

Small and Medium Enterprises (SMEs) in Indonesia continue to experience rapid growth, including Kerupuk Latansa SME in Batam City. However, the packaging activities at this SME are still performed using non-ergonomic work facilities, causing physical complaints among workers. This study aims to identify the level of Musculoskeletal Disorders (MSDs) experienced by workers and to design ergonomic work facilities to improve posture and enhance work comfort. The methods used in this research include posture analysis using RULA (Rapid Upper Limb Assessment) and identification of physical complaints through the Nordic Body Map (NBM) questionnaire. Workers' anthropometric data were used as the basis for designing the work facilities. The results of the study revealed that the most common MSD complaints occurred in the neck, shoulders, back, upper arms, waist, knees, and calves, with a high-risk category. The total percentage of MSD complaints was 64% for Worker 1, 43% for Worker 2, 63% for Worker 3, and 64% for Worker 4. As a solution, an ergonomic worktable was designed with specifications of 90.6 cm in height, 250 cm in length, a partition height of 20 cm, and a table tilt angle of 100°, adjusted according to workers' anthropometric data.

Abstract

This study aims to analyze the physical workload and determine the optimal rest time for welders at PT McDermott Indonesia using a physiological approach. Workload was measured through the Cardiovascular Load (CVL) method and energy consumption based on heart rates during work. The results showed that %CVL ranged from 30%–59%, categorized as "needs improvement." Most workers had energy consumption <5 Kcal/min, but three workers exceeded this threshold: two morning shift level-2 welders (Putra 5.07 Kcal/min; Hotmianto 5.05 Kcal/min) and one night shift level-4 welder (Deo 5.25 Kcal/min). These workers required additional rest times of 11.8 minutes, 8.5 minutes, and 38.7 minutes, respectively. Meanwhile, the standard 30-minute rest period was sufficient for others.

Abstract

This study is a study conducted on the Department Store operator at PT Pegaunihan Tecnology Indonesia, in the manual handling work process workers have a high risk of mulculoskeletal Disorders (MSDs). The study was conducted by observation and distributing questionnaires to workers, the results of the Nordyc Body Map (NBM) questionnaire showed a total of 24 workers complained of upper neck body parts, stiff neck with a percentage of over 90% of workers feeling these complaints. Furthermore, calculations with Rapid Entire Body Assessment (REBA) resulted in 3 workers with the highest risk with a high risk category. From this situation, improvements need to be made. To make improvements, anthropometric data is used, the body dimension data needed in the design is PTD (Front Arm Length), TSB (Standing Elbow Height) and Arm Span. After the calculation, the dimensions of the table were obtained with a width of 70 cm, a length of 110 cm and a height of 103 cm, the complaint value decreased from initially high risk to low risk.

Abstract

Muscoskeletal Disorder is one of the causes of poor work posture during work activities. Efforts to minimize this complaint are by identifying, evaluating, and improving the products that are the work media and body posture while working. This study is a study conducted on the three work activities at UMKM Kerupuk Khas Bandung Rasa Puncar Tower Piayu Batam such as sorting crackers, frying and filtering crackers. Based on the results of body posture with Rapid Entire Body Assessment (REBA) the three activities of sorting crackers, frying and filtering crackers are high-risk activities are frying activities with a bent position when taking or moving raw cracker materials to the fryer or other places can put excessive pressure on the lower spine (lumbar). If workers often lift materials in a non-ideal position, the risk of back and shoulder muscle injuries increases. The improvements made by the researcher were to design a frying table using anthropometric data with the Front Arm Length (JTD) used for a frying pan diameter of 80 cm. Standing Elbow Height (SEL) is used as a benchmark for table height with a result of 100 cm. Hand Span (RT) is used for the length of the cracker frying table with 240 cm by placing 2 frying pans for 2 cracker frying workers.

Abstract

Occupational Safety and Health (OSH) is a crucial aspect in ensuring the well-being of workers and supporting productivity and the continuity of work processes. However, at PT Candi Guna Mandiri, particularly within the Architectural Furniture installation division, there are still indications of low employee awareness regarding OSH practices, which may increase the risk of workplace accidents. This study aims to analyze the factors influencing employee awareness of OSH, including knowledge, attitude, training, managerial supervision, age, and work experience. The research uses a quantitative approach with a descriptive-analytic design and total sampling involving 79 respondents. Data were collected using a questionnaire that had been tested for validity and reliability. Data analysis was conducted using the Spearman correlation test. The results showed that among the six independent variables examined, only two had a statistically significant relationship with OSH awareness: training (r = 0.279; r = 0.013) and managerial supervision (r = 0.410; r = 0.000). Other variables - knowledge, attitude, age, and work experience - did not show a significant correlation. It can be concluded that OSH awareness among employees is more influenced by institutional approaches, such as effective training and consistent supervision. Therefore, the company is advised to strengthen its training and supervision systems to foster a work culture that is more aware of occupational safety and health.
