Noise Level Management Design to Reduce Noise Exposure Dosages in the Guard Shop Production Unit in Jakarta Electronic Companies

Introduction

The Guard Shop Production Unit in an electronic company in Jakarta produces crucial components such as the front guard and rear guard, which functions as a protector of fan products. However, in this production area, there are serious problems related to noise. The noise produced from the production process reaches between 87 to 93 dB (A) and lasts for 7.8 hours every day. This noise level has exceeded the threshold set by the government in the Decree of the Minister of Manpower No. Kep.51/Men/1999. The impact of this noise is very detrimental, including causing hearing loss, work discomfort, and communication disorders among workers.

The Importance of Noise Level Management

Noise level management is crucial in the Guard Shop production unit to ensure the health and safety of workers. Prolonged exposure to high noise levels can lead to permanent hearing damage, decreased productivity, and increased risk of accidents. The government has set a threshold for noise levels in the workplace, and it is the responsibility of the company to ensure that this threshold is not exceeded.

Methodology

This study aims to manage and reduce the noise level in the Guard Shop production unit, so that the exposure received by the operators remains within safe limits. In this study, the approach used is a descriptive design with the survey method. Some of the observed variables include the type and age of the engine, the position of the production machine, the noise level, the duration of exposure, spatial temperature, air velocity, and noise dose. To measure noise and temperature level, Sound Level Meter Integrating/Logging Model 2900 and Digital Type Corona Type GL-89 Model were used. Meanwhile, additional data were obtained from company note files.

Results

The results of data processing show that noise in the Guard Shop production unit exceeds a safe threshold. Noise was recorded in several production areas, such as Middle Ring Welding with a noise level of 88.04 dB (A), Cutting 91.65 dB (A), Outer Ring Welding 89.95 dB (A), Forming 89.95 dB (A), and Projection Welding 87.71 dB (A). Based on these data, the working hours allowed for each area were: Middle Ring Welding for 237 minutes, Cutting 103 minutes, Outer Ring Welding 153 minutes, Forming 153 minutes, and Projection Welding 256 minutes.

Noise Level Management Design

As a solution, the noise level management design in the Guard Shop production unit is proposed through control administration by carrying out work rotation. Operators that have been exposed to noise for the amount of working hours that are permitted will be transferred to a safer work area and free of high noise.

Additional Analysis and Explanation

This noise management action is very important not only to meet government regulations, but also to create a healthier and more productive work environment. High noise can reduce concentration and work efficiency, as well as increasing the risk of accidents at work. With the work rotation, it is expected that not only noise exposure can be reduced, but also employee comfort and productivity can be increased.

The Role of Technology in Noise Level Management

The use of appropriate measurement technology in this study is the key to obtaining accurate data about the current noise conditions. This is important in planning effective mitigation steps. In addition, companies can also consider investment in more modern and efficient equipment, which can contribute to reducing noise in its source.

Training and Education for Employees

Meanwhile, training and education for employees regarding noise risk and preventive measures are also very necessary. Awareness of the importance of maintaining hearing health must be instilled early on. With a comprehensive approach, both in terms of noise and education management, it is expected that the Guard Shop production unit can operate more securely and efficiently in the future.

Conclusion

In conclusion, noise level management is crucial in the Guard Shop production unit to ensure the health and safety of workers. The proposed noise level management design through work rotation is expected to reduce noise exposure and increase employee comfort and productivity. The use of technology and training and education for employees are also essential in achieving a healthier and more productive work environment.

Recommendations

Based on the findings of this study, the following recommendations are made:

The company should implement the proposed noise level management design through work rotation to reduce noise exposure and increase employee comfort and productivity.
The company should invest in more modern and efficient equipment to reduce noise in its source.
The company should provide training and education for employees regarding noise risk and preventive measures.
The company should conduct regular noise level measurements to ensure that the threshold set by the government is not exceeded.

By implementing these recommendations, the Guard Shop production unit can operate more securely and efficiently in the future.
