Ergonomics Analysis Re-Design of Employee Work Chair Stamping at PT. SC Johnson Manufacturing Medan

Abstract

In today's fast-paced work environment, employee comfort and health are crucial factors that contribute to productivity and overall well-being. One of the most important work facilities for employees who do work in a sitting position is the chair. However, the use of non-ergonomic chairs can result in poor work posture and negative impacts on the health of the spine. Musculoskeletal disorders (MSDs) are a significant concern for companies, as they can lead to increased healthcare costs and additional costs to produce defective products. This study aims to analyze the ergonomic design of employee work chairs at PT. SC Johnson Manufacturing Medan (PT. SCJMM) and propose a re-design to reduce health risks.

Introduction

PT. SCJMM is a leading manufacturer of anti-mosquito products, and its employees in the stamping section are responsible for product inspection and sorting. However, the current chair used in this section does not meet ergonomic standards, particularly in terms of height and backrest. This can lead to discomfort, pain, and even musculoskeletal disorders among employees. The use of Nordic Questionnaire (SNQ) standards to identify problems has shown that employees often experience complaints of pain in the waist, buttocks, and back. Therefore, it is essential to re-design the chair to reduce health risks and improve employee comfort.

Re-Design Approach

The re-design process of the sorting chair involved an anthropometric approach, which takes into account the physical characteristics of employees. Before re-designing, the analysis was carried out on the results of the SNQ questionnaire, the current chair dimension, and employee work posture. The re-designed chair was designed with adjustable height and equipped with a backrest to support employee comfort and health.

Methodology

The study employed a mixed-methods approach, combining both qualitative and quantitative data collection and analysis methods. The SNQ questionnaire was used to identify problems and gather data on employee complaints. The current chair dimension and employee work posture were also analyzed to inform the re-design process. The re-designed chair was then simulated, and the employee's work posture was recorded to evaluate the effectiveness of the re-design.

Results

The results showed that the current employee's work posture was at level 6, indicating an urgent need for improvement to avoid the possibility of musculoskeletal disorders. After the simulation of the use of the re-designed chair, the employee's work posture was recorded at level 3, indicating a significant reduction in health risks. This suggests that the re-designed chair is more ergonomic and can reduce the risk of musculoskeletal disorders among employees.

Added Value and Benefits

Ergonomic chair design not only helps reduce employee health complaints but can also increase work productivity. Employees who feel comfortable tend to be more focused and can carry out tasks better. In addition, companies can also feel the benefits of reducing medical costs due to musculoskeletal disorders, as well as improving the quality of the products produced due to better employee concentrations.

Conclusion

The re-design of the employee work chair at PT. SC Johnson Manufacturing Medan has shown significant benefits in reducing health risks and improving employee comfort. The use of an anthropometric approach and the SNQ questionnaire has informed the re-design process, resulting in a more ergonomic chair that can reduce the risk of musculoskeletal disorders. This study highlights the importance of ergonomic design in creating a healthier work environment and contributing to the efficiency and sustainability of company operations.

Recommendations

Based on the findings of this study, the following recommendations are made:

Implement the re-designed chair: PT. SC Johnson Manufacturing Medan should implement the re-designed chair in the stamping section to reduce health risks and improve employee comfort.
Conduct regular ergonomic assessments: Regular ergonomic assessments should be conducted to identify potential problems and inform the re-design process.
Provide training and education: Employees should be provided with training and education on the importance of ergonomic design and how to use the re-designed chair correctly.
Monitor and evaluate: The effectiveness of the re-designed chair should be monitored and evaluated regularly to ensure that it continues to meet the needs of employees.

By implementing these recommendations, PT. SC Johnson Manufacturing Medan can create a healthier work environment, reduce health risks, and improve employee comfort and productivity.
