Introduction

In today's fast-paced industrial environment, companies are constantly seeking ways to improve productivity and reduce operator complaints. One approach that has gained significant attention in recent years is Macroergonomic Analysis and Design (MEAD). This method analyzes and designs a comprehensive work system, taking into account human factors and the work environment. In this case study, we will explore the application of MEAD to CV. Topaz Profile and Frame, a private company engaged in the industry of manufacturing profiles and frames.

Background

CV. Topaz Profile and Frame has five work stations: Blower, Mixing, Mintage, Coating, and Cutting & Packing. The focus of this study lies on the Cutting & Packing Station, which is faced with the challenges of engine design and a hot and dusty work environment. As a result, operators experience discomfort and complaints. The company's goal is to design more ergonomic work facilities to reduce operator complaints and increase work productivity.

Methodology

To achieve this goal, this study uses the MEAD approach, which involves the analysis and design of the work system by considering anthropometric, biomechanical, and psychosocial factors. The Standard Nordic Questionnaire (SNQ) method is used to identify operator complaints at each work station. The results showed a significant complaint at the Cutting & Packing Station, especially related to less ergonomic work posture.

Identifying Problems and Finding Solutions

The Rapid Entire Body Assessment (Reba) method is used to analyze the operator's work posture and determine the optimal design requirements for work facilities. The results of the Reba analysis showed that the operator's work posture was not optimal, leading to discomfort and complaints. To overcome this problem, researchers designed new work facilities in the form of work chairs with specifications:

Backrest width: 44.62 cm
Backrest height: 65.36 cm
Sitting Length: 44.88 cm
Height of chairs and adjustable footrests

Application of Mead to Increase Work Comfort

The new work facilities design is designed to ensure more emphasis and more ergonomic work posture for operators, thereby reducing the risk of injury and increasing productivity. The design takes into account the anthropometric, biomechanical, and psychosocial factors of the operators, ensuring that the work facilities are comfortable and effective.

Significant Results

After the application of new work facilities design, an increase in operator productivity at the Cutting & Packing station looks significant. The work in one day increased from 466 profiles of profiles to 488 rod profiles. This shows that the application of Mead can be an effective solution to improve work efficiency and productivity in the industrial environment.

Conclusion

This study proves that the application of Mead in the design of work facilities can significantly increase the comfort and productivity of operators in the industrial environment. By understanding the needs of the operator and analyzing the factors that affect the work environment, Mead allows more ergonomic and effective designs. In addition, this research provides several important points for the design of work facilities in the manufacturing industry:

The Importance of Work Posture Analysis

The Reba method can be an effective tool to identify work posture problems and design the right solution. By analyzing the operator's work posture, designers can identify areas for improvement and design work facilities that are comfortable and effective.

Adjustable Work Facility Design

Work chairs with adjustable features can be adjusted to the needs of different operators, thereby ensuring optimal comfort and productivity. This design allows operators to adjust the work facilities to their individual needs, ensuring that they are comfortable and effective.

The Importance of Paying Attention to Psychosocial Factors

Mead not only focuses on physical factors, but also considers psychosocial factors such as motivation and job satisfaction, which can increase the effectiveness of the work system as a whole. By considering these factors, designers can create work facilities that are not only comfortable and effective but also motivating and satisfying.

Recommendations

Based on the findings of this study, we recommend that CV. Topaz Profile and Frame and other companies in the manufacturing industry apply the principles of Mead to design more ergonomic work facilities. By doing so, they can increase the comfort and productivity of their operators, improve the quality and efficiency of the production process, and contribute to a healthier and safer work environment.

Limitations

This study has several limitations. Firstly, the study was conducted in a single company, and the results may not be generalizable to other companies. Secondly, the study only focused on the Cutting & Packing Station, and the results may not be applicable to other work stations. Finally, the study only considered a limited number of factors, and the results may not be comprehensive.

Future Research Directions

Future research should aim to replicate this study in other companies and work stations to confirm the findings and generalize the results. Additionally, future research should consider a wider range of factors, including physical, biomechanical, and psychosocial factors, to provide a more comprehensive understanding of the factors that affect work comfort and productivity.

Conclusion

In conclusion, this study demonstrates the effectiveness of Mead in improving work comfort and productivity in the industrial environment. By applying the principles of Mead, companies can create a healthier, safer, and more productive work environment for their operators, thereby contributing to the improvement of the quality and efficiency of the production process.

Introduction

Macroergonomic Analysis and Design (MEAD) is a method used to analyze and design a comprehensive work system, taking into account human factors and the work environment. In this article, we will answer some frequently asked questions about MEAD to provide a better understanding of this method.

Q: What is Macroergonomic Analysis and Design (MEAD)?

A: MEAD is a method used to analyze and design a comprehensive work system, taking into account human factors and the work environment. It involves the analysis and design of the work system by considering anthropometric, biomechanical, and psychosocial factors.

Q: What are the benefits of using MEAD?

A: The benefits of using MEAD include:

Improved work comfort and productivity
Reduced operator complaints and injuries
Increased efficiency and effectiveness of the production process
Improved quality and safety of the work environment

Q: How does MEAD differ from other ergonomic analysis methods?

A: MEAD differs from other ergonomic analysis methods in that it considers a comprehensive range of factors, including anthropometric, biomechanical, and psychosocial factors. This allows for a more holistic understanding of the work system and the factors that affect it.

Q: What are the key steps involved in the MEAD process?

A: The key steps involved in the MEAD process are:

Analysis: Identify the work system and the factors that affect it
Design: Design the work system to meet the needs of the operators and the organization
Implementation: Implement the designed work system
Evaluation: Evaluate the effectiveness of the designed work system

Q: What tools and techniques are used in MEAD?

A: The tools and techniques used in MEAD include:

Standard Nordic Questionnaire (SNQ): A method used to identify operator complaints and discomfort
Rapid Entire Body Assessment (Reba): A method used to analyze the operator's work posture and determine the optimal design requirements for work facilities
Anthropometric analysis: A method used to analyze the physical characteristics of the operators and the work environment
Biomechanical analysis: A method used to analyze the physical demands of the work and the operator's ability to perform the task
Psychosocial analysis: A method used to analyze the psychological and social factors that affect the work environment and the operators
