Ergonomic Work Facility Design Using the Quality Function Deployment (QFD) Method on UD. M. Irfan Shoes

Introduction

In today's fast-paced industrial world, the importance of ergonomic work facilities cannot be overstated. A well-designed work facility not only improves the productivity and comfort of workers but also reduces the risk of injury and musculoskeletal complaints. However, many small industries, including shoe manufacturers like UD. M. Irfan Shoes, often struggle to provide adequate work facilities due to limited resources and inadequate knowledge of ergonomic design principles. This article discusses the application of the Quality Function Deployment (QFD) method in designing ergonomic work facilities for UD. M. Irfan Shoes, with a focus on improving the assembly process and reducing the risk of injury to operators.

The Problem of Inadequate Work Facilities

UD. M. Irfan Shoes, like many small industries, faces several challenges in its production process. One of the major issues is the lack of adequate work facilities, which can be seen in the absence of a workpiece holder during the assembly process between the upper shoe section and the shoe reference. As a result, operators are forced to clamp the workpiece using their thighs, leading to musculoskeletal complaints and discomfort. Furthermore, the work chair used by operators is not ergonomic, made of cans and pillows as a sitting base, which does not match the dimensions of the operator's body. The layout of the components is also less organized, resulting in an unproductive work attitude and musculoskeletal complaints in the operator.

The Importance of Ergonomic Work Facilities

Ergonomic work facilities are essential for improving the productivity and comfort of workers. A well-designed work facility can reduce the risk of injury and musculoskeletal complaints, improve worker morale, and increase productivity. In the context of UD. M. Irfan Shoes, the improvement of work facilities is a must to overcome the problems faced by operators. The study aims to design an ergonomic workpiece clamp and work chair using the Quality Function Deployment (QFD) method.

The Quality Function Deployment (QFD) Method

The QFD method is a powerful tool for transforming the desires and needs of customers or operators into technical specifications that can be implemented in the design of work facilities. This method helps to identify the key factors that affect the quality of work facilities and prioritize them based on their importance. The QFD method involves several steps, including:

Customer Requirements: Identifying the desires and needs of operators, including their preferences and requirements for work facilities.
Technical Requirements: Translating customer requirements into technical specifications that can be implemented in the design of work facilities.
Design: Designing the work facilities based on the technical specifications.
Verification: Verifying the design of work facilities to ensure that they meet the technical specifications.

Data Processing and Analysis

The study begins with data processing from the Standard Nordic Questionnaire (SNQ), which identifies musculoskeletal complaints in various parts of the operator's body. The results of work posture analysis through the Rapid Upper Limb Assessment (RULA) show that there are many elements of movement in work postures that are not in accordance with ergonomic principles. The data processing and analysis help to identify the key factors that affect the quality of work facilities and prioritize them based on their importance.

Designing Ergonomic Work Facilities

The study designs an ergonomic workpiece clamp and work chair using the QFD method. The design is based on anthropometric data and operator preferences, which are obtained through the QFD method. The designed improvement includes a workpiece holder that can be easily adjusted to fit the dimensions of the operator's body, and a work chair that is designed to provide optimal support and comfort for the operator.

Results and Discussion

The results of the study show that the designed ergonomic work facilities can improve the productivity and comfort of operators. The time needed to complete the assembly process with the new work facility is identified to be 228 seconds, which means there is a reduction in time of 87 seconds or a decrease of 28.61%. The results also show that the designed ergonomic work facilities can reduce the risk of injury and musculoskeletal complaints in operators.

Conclusion

The application of the QFD method in designing ergonomic work facilities for UD. M. Irfan Shoes is an important step to improve the welfare of the workforce and the quality of production. The study demonstrates the effectiveness of the QFD method in transforming customer requirements into technical specifications that can be implemented in the design of work facilities. The results of the study show that the designed ergonomic work facilities can improve the productivity and comfort of operators, reduce the risk of injury and musculoskeletal complaints, and increase the quality of production.

Recommendations

Based on the results of the study, the following recommendations are made:

Implement the designed ergonomic work facilities: The designed ergonomic work facilities should be implemented in the production process to improve the productivity and comfort of operators.
Continuously monitor and evaluate the work facilities: The work facilities should be continuously monitored and evaluated to ensure that they meet the technical specifications and customer requirements.
Provide training and education: Operators should be provided with training and education on the use and maintenance of the designed ergonomic work facilities.
Invest in better work facilities: Small industries like UD. M. Irfan Shoes should invest in better work facilities to improve the welfare of the workforce and the quality of production.

Future Research Directions

The study provides several future research directions, including:

Further improvement of the QFD method: The QFD method can be further improved by incorporating new techniques and tools, such as artificial intelligence and machine learning.
Application of the QFD method in other industries: The QFD method can be applied in other industries, such as manufacturing, healthcare, and education, to improve the quality of work facilities and reduce the risk of injury and musculoskeletal complaints.
Development of new ergonomic work facilities: New ergonomic work facilities can be developed using the QFD method to improve the productivity and comfort of operators.
