Design of Working Aids for Inspection Operators at the Sutting Station with an Ergonomics Approach at PT. Florindo Makmur Medan

Introduction

PT. Florindo Makmur Medan is a company engaged in the manufacturing of cassava processing into tapioca flour, with a daily production of around 420 tons. The company operates in two work shifts for 25 days a month, with a total of 24 operators working at each shift. The operators work in seven work stations, including the Greening Station, where the inspection process takes place. However, the current working conditions at the Greening Station do not support the efficiency and health of the operators. The chair used by the operators has a height of 35 cm, while the conveyor belt wall is as high as 50 cm and a length of 60 cm. This non-ergonomic work attitude causes unnatural muscle movements and energy waste, which can ultimately risk causing muscle fatigue and injury.

The Importance of Ergonomic Work Aids Design

The main objective of this research is to design work aids that can increase the comfort and productivity of inspection operators at the STILLETE station. This design is expected to reduce the complaints of musculoskeletal that are often experienced by operators. The research took place between September 2016 and January 2017 at PT. Florindo Makmur Medan, with a focus on identifying the physical complaints of operators through interviews and distribution of health survey (SNQ). The interview results show complaints of pain that focuses on certain body parts.

From the analysis, it was found that the average score of the complaints of musculoskeletal inspection operators reached 42. The highest percentage of complaints occurred on the left and right shoulder and buttocks, reaching 6.587%. Meanwhile, the waist and buttocks record the percentage of 5.988%. Complaints to the back, arms, elbows, and wrists are also significant, with a percentage of 5,389%. The results of the assessment of the pain level show that 41.96% of the operators experienced illness, 17.86% felt very sick, and 11.61% felt somewhat sick.

Work Posture Assessment and Design Implementation

To understand more deeply about the operator's work posture, an assessment is carried out using a Reba Worksheet. The score obtained shows that the operator's work posture is in the moderate risk category, so immediate improvement is needed. The improvement action taken in this study was to design work aids such as chairs, tables, and cutting devices that were adjusted to the body's body dimensions.

Anthropometric data collected is the basis for designing ergonomic tools. By using the principle of anthropometry, it is important to understand extreme dimensions, such as shoulder and hip width, as well as horizontal range when sitting and diameter of grip. In addition, the average dimension, such as the height of the sitting elbow and the height of the popliteal is also taken into account. By processing this data, the design of appropriate tools can be produced, assisting operators in carrying out their duties more efficiently and comfortably.

Design of Ergonomic Work Aids

The design of ergonomic work aids is a crucial step in creating a healthier and more efficient work environment. The design of work aids such as chairs, tables, and cutting devices should be adjusted to the body's body dimensions. The use of anthropometric data is essential in designing ergonomic tools that can assist operators in carrying out their duties more efficiently and comfortably.

The design of ergonomic work aids should take into account the following factors:

Anthropometric data: The use of anthropometric data is essential in designing ergonomic tools that can assist operators in carrying out their duties more efficiently and comfortably.
Work posture analysis: The analysis of work posture is crucial in identifying the physical complaints of operators and designing work aids that can reduce the risk of musculoskeletal injury.
Ergonomic principles: The design of ergonomic work aids should be based on ergonomic principles, such as the principle of anthropometry, to ensure that the tools are designed to fit the body's body dimensions.

Conclusion

Ergonomic Working Aid Design at PT. Florindo Makmur Medan is expected to not only increase operator comfort, but also reduce the risk of musculoskeletal injury. With better working conditions, operator productivity will also increase, which ultimately contributes to the company's success in meeting the target production of tapioca flour. Design implementation based on anthropometric data and work posture analysis is an important step in creating a healthier and more efficient work environment.
