Ergonomic Tests on the Mechanical Rice Seeds of the Dapog System: A Study on Operator Fatigue and Tool Design

Introduction

Ergonomics is a crucial aspect of designing tools and equipment to ensure that they are physically suitable for use by operators. In the context of agricultural tools, such as the Dapog Mechanical Rice Seeds, it is essential to evaluate the dimensions of the tool in relation to the human body and measure the level of fatigue experienced by the operator. This study aims to investigate the ergonomic aspects of the Dapog Mechanical Rice Seeds and provide recommendations for improving the design of the tool to reduce operator fatigue.

Background

The Dapog Mechanical Rice Seeds is a tool used in agricultural settings to facilitate the process of planting rice seeds. However, the design of the tool may not be optimized for the physical needs of the operator, leading to fatigue and discomfort. Ergonomic studies have shown that the design of tools and equipment can significantly impact the level of fatigue experienced by operators, which can ultimately affect their productivity and health.

Methodology

This study involved 100 students of agricultural engineering study programs, Faculty of Agriculture, University of North Sumatra, as correspondents. The participants were asked to perform tasks using the Dapog Mechanical Rice Seeds, and various data were collected, including:

Hand coverage length: The length of the hand coverage was measured to determine the distance between the operator's hands and the tool.
Hip distance to the sole of the feet: The distance between the operator's hip and the sole of their feet was measured to determine the comfort level of the operator while using the tool.
Pulse measurement: The pulse of the operator was measured before and after work to determine the level of fatigue experienced.

Results

The results of the study showed that the high hopper of the tool reached 45.7 cm, which was declared ergonomic for the operator. Additionally, the height of the bottom frame, which reached 70 cm, was also classified as ergonomic. However, despite the tool meeting ergonomic standards, the study found that there was a working position that caused a higher level of fatigue. The operator responsible for filling the ground into the hopper and lifting the tray containing rice seeds experienced more fatigue levels than other positions.

Operator Fatigue Analysis

Operator fatigue is a significant concern in agricultural settings, where physical activity is a major part of the work. Excessive fatigue can lead to a decrease in productivity and increased risk of injury. The high level of fatigue in operators can affect their long-term work efficiency and health. In the context of agriculture, it is essential to identify fatigue-prone points in order to take precautions.

Recommendations

Based on the findings of this study, the following recommendations are made to reduce operator fatigue:

Rotation system of work position: A rotation system of work position (rolling operator) can be implemented to distribute the workload and allow each operator to have the opportunity to rest periodically.
Better work position settings: Steps can be taken to improve the work position settings, such as adjusting the height and angle of the tool to reduce the level of fatigue experienced by the operator.
Ergonomic design: The design of the tool can be improved to reduce the level of fatigue experienced by the operator. This can be achieved by incorporating ergonomic principles, such as reducing the weight and size of the tool, and improving the grip and handle design.

Conclusion

This research provides valuable insights about the suitability of the Dapog Mechanical Rice Seeds from the ergonomic point of view. By paying attention to the device dimensions and operator working conditions, we can increase the design of the tool to be more in line with the physical needs of humans. Furthermore, steps such as better work position settings and rotation systems can help reduce fatigue levels, ensuring operators can work more comfortably and productively. Continuous efforts in research and development of ergonomic agricultural tools are very important to improve the efficiency and welfare of farmers.

Future Directions

Future studies can build on the findings of this research by investigating the impact of ergonomic design on operator fatigue and productivity. Additionally, studies can explore the development of new tools and equipment that incorporate ergonomic principles to reduce operator fatigue and improve work efficiency.

Limitations

This study had several limitations, including the small sample size and the use of a specific tool (Dapog Mechanical Rice Seeds). Future studies can address these limitations by using a larger sample size and investigating the ergonomic aspects of different tools and equipment.
