Introduction

Understanding the Importance of Lighting in the Workplace

In today's fast-paced industrial environment, the importance of proper lighting in the workplace cannot be overstated. One of the key areas where lighting plays a crucial role is in the plastic sorting department of CV. Plastic Lestari Mitra, a company engaged in the processing of plastic seeds. Located on Jalan Pelita II No. 22, Medan Star Industrial Area, Tanjung Morawa, this company relies heavily on the efficiency and productivity of its workers to meet the demands of its customers. However, inadequate lighting rates in the plastic sorting room can lead to eye fatigue, increase the risk of error, and ultimately affect the overall quality of the products.

The Problem Formulation

The problem formulation faced by CV. Plastic Lestari Mitra focuses on the impact of adequate lighting on the level of error in plastic sorting. The purpose of this study is to explore the relationship between the intensity of lighting and employee eye fatigue, as well as to reduce plastic packaging errors that do not meet qualifications. By understanding the effects of lighting on worker productivity and eye health, the company can take steps to improve the working conditions and reduce the risk of errors.

Research Methodology

Designing the Study

This study involved testing of lighting intensity at different levels, namely 150, 200, 250, and 300 lux, as well as work rotation intervals for 20 and 30 minutes, and the division of work shifts divided into three categories. The tool used to measure the eye fatigue is the Flicker Fusion Frequency Test, which gives an overview of the level of working resistance to fatigue due to non-optimal lighting. The data collected was then analyzed using several statistical methods, including normality testing (Kolmogorov-Smirnov) and Bartlett tests for data uniformity, followed by variance analysis (anava) and factorial experiments.

Results and Findings

Analyzing the Data

The results of the analysis showed that the three factors were tested - the intensity of lighting, work rotation intervals, and work shifts - had a significant influence on the value of flicker fusion frequency. In addition, a correlation coefficient was obtained by 0.523 between the value of Flicker Fusion Frequency and plastic packaging that did not meet the qualifications, which indicated a rather low relationship but quite significant.

Furthermore, in experiments with 250 lux lighting intensity and 20-minute work rotation interval, an error rate recorded is only 13.043%. Meanwhile, in conditions with a lighting intensity of 150 lux and a rotation interval of 30 minutes, the percentage of errors increased significantly to 39.286%. This finding shows that lighting optimization of up to 250 Lux can increase productivity and reduce errors in plastic sorting in CV. Plastic Lestari Mitra.

Recommendation

Improving Working Conditions

Based on the results of the study, it is recommended that the company increases the intensity of lighting with the addition of lights in the sorting area. In addition, choosing a 20-minute work rotation interval and compiling a good work shift turnover schedule will be very useful in reducing employee eye fatigue. With the application of this recommendation, it is hoped that a more comfortable, productive, and quality work environment can be created in CV. Plastic Lestari Mitra.

Applying the Recommendations

Applying these steps will not only improve employee performance, but also reduce the risk of errors that can have an impact on product quality. Therefore, it is important for management to pay attention and apply the results of this study for the progress and success of the company in the future.

Conclusion

The Importance of Lighting in the Workplace

In conclusion, the study highlights the importance of proper lighting in the workplace, particularly in the plastic sorting department of CV. Plastic Lestari Mitra. By understanding the effects of lighting on worker productivity and eye health, the company can take steps to improve the working conditions and reduce the risk of errors. The recommendations provided in this study can serve as a guide for the company to improve its working conditions and create a more comfortable, productive, and quality work environment.

Future Directions

Continuing Research

This study provides a foundation for further research on the impact of lighting on worker productivity and eye health. Future studies can explore the effects of different lighting intensities and schedules on worker performance and eye fatigue. Additionally, research can be conducted on the economic benefits of improving working conditions and reducing errors in the plastic sorting department.

Implementing the Recommendations

Implementing the recommendations provided in this study can have a significant impact on the productivity and quality of work in the plastic sorting department of CV. Plastic Lestari Mitra. By increasing the intensity of lighting and implementing a 20-minute work rotation interval, the company can reduce the risk of errors and improve the overall quality of its products.
Frequently Asked Questions (FAQs) about Lighting Intensity in the Plastic Sorting Department

Q: What is the importance of proper lighting in the workplace?

A: Proper lighting in the workplace is crucial for employee productivity, eye health, and overall quality of work. Inadequate lighting can lead to eye fatigue, increase the risk of error, and affect the overall quality of products.

Q: What are the factors that affect the level of lighting intensity in the plastic sorting department?

A: The factors that affect the level of lighting intensity in the plastic sorting department include the intensity of lighting, work rotation intervals, and work shifts.

Q: What is the recommended lighting intensity for the plastic sorting department?

A: The study recommends a lighting intensity of up to 250 Lux for the plastic sorting department. This level of lighting has been shown to increase productivity and reduce errors in plastic sorting.

Q: What is the impact of work rotation intervals on employee eye fatigue?

A: The study found that a 20-minute work rotation interval can reduce employee eye fatigue and improve productivity. This is because shorter work rotation intervals allow employees to take breaks and rest their eyes, reducing the risk of eye fatigue.

Q: What is the correlation between Flicker Fusion Frequency and plastic packaging errors?

A: The study found a correlation coefficient of 0.523 between Flicker Fusion Frequency and plastic packaging errors. This indicates a significant relationship between the two variables, suggesting that Flicker Fusion Frequency can be used as an indicator of plastic packaging errors.
