Abstract

Material handling activities in the Inspecting Department of PT Behaestex are still carried out manually, particularly in the process of moving fabric rolls. Fabric rolls weighing approximately 30 kg have to be moved repeatedly, potentially increasing the physical workload of operators. This study aims to determine the level of physical workload of operators, design a material handling aid that meets operator needs and working area conditions, and evaluate changes in physical workload after using the material handling aid. Physical workload was measured using the Cardiovascular Load (%CVL) method based on working and resting pulse rates involving 12 material handling operators. The trolley was designed by considering operator anthropometric data and the working path conditions, which had a width of approximately 1 meter. The measurement results showed that the average %CVL value before using the trolley was 60.1%, while after using the trolley it decreased to 29.7%. Thus, there was a reduction of 30.4 percentage points compared with the initial condition. In addition, material handling operator productivity increased, with the average output rising from 80.4% before using the trolley to 95.3% of the established target of 95%, representing an increase of 14.9 percentage points. These results indicate that the use of the trolley reduced operator fatigue, as indicated by the decrease in physical workload based on the %CVL value. The designed trolley can serve as an alternative material handling aid for fabric roll transportation activities in the Inspecting Department.

Abstract

PT EQY is a textile company, especially yarn spinning. The activities of the staffing/packing department at PT EQY are packing, lifting, and moving cardboard boxes. This activity still relies on human power or manual material handling. This work is carried out repeatedly and continuously, causing complaints of pain in several parts of the body during work. This raises the risk of work postures such as Musculoskeletal disorders (MSDs). This research aims to produce a design for work aids that can reduce the risk of Musculoskeletal disorders (MSDs) using the Ovako Work Analysis System (OWAS) method. Based on the problem, work posture analysis was carried out using the OWAS method to find out whether the work posture of staffing/packing employees falls into the risky posture category or not. Based on the results of the Ovako Work Analysis System (OWAS) analysis research, it shows that the posture of staffing/packing workers is included in the high risk category and needs immediate improvement. This improvement involves designing work facilities, namely a handlift and packing table with an ergonomics approach, resulting in a handlift design with a height of 200 cm (2000 mm) and a packing table with a width of 200 cm (2000 mm) and a packing table with a length of 60 cm (600mm), width 60 cm(600mm), and height 104 cm(1040mm).

Abstract

Work fatigue is a significant issue faced by employees in Indonesia, with approximately 65% experiencing symptoms that reduce their concentration and performance. Excessive workload, particularly mental workload, can result in cognitive strain and decreased productivity. This study aims to measure the level of mental workload experienced by quality control employees at PT Delta Dunia Tekstil I using the NASA Task Load Index (NASA-TLX) method. The research also investigates the relationship between employees’ age, length of service, and perceived mental workload through T-tests and F-tests to provide a more comprehensive analysis. Data were collected from 20 quality control employees who are responsible for monitoring textile production under strict standards. Results from NASA-TLX calculations indicate that the average mental workload falls within the high category, with effort and own performance emerging as the dominant dimensions contributing to mental strain. Correlation analysis shows a negative but not statistically significant relationship between age, length of service, and mental workload, suggesting that other factors play a stronger role in shaping employees’ perceptions. The study further highlights fluctuations in employee attendance and quality performance indicators, emphasizing the importance of workload evaluation. To address these issues, recommendations include adding more operators per machine, which is projected to reduce mental workload scores by approximately 33%. Such measures can optimize task distribution, improve efficiency, and promote employee well-being. Overall, the findings suggest that systematic workload assessments using tools such as NASA-TLX are essential for enhancing productivity and supporting sustainable human resource management in the textile industry.

Abstract

This study was conducted to analyze the causes of occupational accidents and to identify potential hazards in the material cutting process at PT Kanaan Global Indonesia using the Job Safety Analysis (JSA) approach. The high number of occupational accidents, totaling 15 cases during the period of December 2024–May 2025, indicates the existence of gaps in occupational safety control in this area. Data were collected through direct observation, interviews with workers, and the collection of historical data from the Occupational Health and Safety (OHS) unit. Risk analysis was carried out using a risk matrix to determine likelihood and severity values, followed by JSA for each work stage. The results identified 25 potential hazards, consisting of 4 risks in the extreme category, 9 in the high category, 7 in the medium category, and 5 in the low category. High-risk hazards were predominantly found in roll cutting and cutting press machines, which are characterized by mechanical hazards. Control recommendations focus on the implementation of engineering controls such as the installation of guarding systems and safety light curtains, improvements in safe work procedures, and increased discipline in the use of personal protective equipment (PPE). These findings demonstrate that the JSA method provides a comprehensive overview of risk sources and serves as an effective basis for formulating occupational accident control strategies within the company.

Abstract

Low productivity and high sick leave in the weaving division of PT XYZ in Yogyakarta are caused by excessive physical and mental workload on Shuttle Loom Unit 2 operators. The productivity of the weaving division of PT XYZ was recorded at only 61.96% (target 75%) with sick leave of 4.17%, indicating operator fatigue. This study measured physical workload using the Cardiovascular Load (CVL) method based on heart rate and mental workload using NASA-TLX, and analyzed the correlation with age and length of service. The results showed a moderate physical workload category (40% light CVL <30, 60% moderate 30-60) at a temperature of 30.5°C, and high-very high mental workload (45% high 50-79, 55% very high ≥80, average EF 79.3) due to strict quality targets (0.5% defects). There is a correlation between CVL and NASA-TLX with age. Recommendations include reducing the daily production target from 100 to 85-88 yards, optimizing ergonomics, and training to reduce EF to 65 and defects to 0.3, to increase effective productivity.

Abstract

PT. X is a textile company that produces greige fabric. One of the crucial stages in the greige fabric production process is inspection. Currently, the facility layout of the inspection area at PT X is still suboptimal. This results in longer fabric movement distances and increased time, leading to delivery delays and higher material handling costs. This study aims to design an optimal facility layout in the inspection area using the Activity Relationship Chart (ARC) method and to determine the distances, times, and costs for the proposed layout. In the initial production layout, the fabric movement distance reached 26,130 meters in one working day, and the fabric movement time was 936 minutes. Furthermore, the initial production layout generated a relatively high OMH of Rp 13,742,980 per month. After designing the facility layout using the Activity Relationship Chart (ARC) and Blockplan methods, the proposed layout was arranged according to the production process sequence, resulting in a smoother material flow. The proposed layout yields 16,830 meters of fabric movement per workday, 660 minutes of required time, and a monthly OMH of Rp 7,945,622, with an efficiency of 39.32%.
