Correlation between Knowledge Level of Noise Hazard and Compliance with Using Ear Protectors

THE RELATIONSHIP LEVELS OF KNOWLEDGE ABOUT THE HAZARDS OF NOISE WITH COMPLIANCE IN THE USE OF EAR PROTECTION IN WORKERS OF THE TEXTILE WEAVING UNIT FACTORY OF PT. PANDATEX MAGELANG
 
Background. By definition, unwanted sound can be said as
noisy. The progress of civilization has shifted industrial development towards the use of motorized vehicle engines, factory machines, heavy transportation equipment, and so on. The effect of this noise is very large. For example, acoustic trauma or systemic disturbances caused by noise in the workplace, systemic disturbances caused by noise, decreased ability to work, if calculated the loss in nominal terms can reach billions of rupiah. For this reason, health workers need to recognize the effect of noise on the health of workers, carry out early detection and control of noise in the workplace. Noise-induced hearing loss (NIHL = Noise Induced Hearing Loss) is often found in industrial workers in both developed and developing countries. This is mainly industrialized countries that have not implemented a proper protection system. Indonesia can be called a developing industrial country, so that in an effort to increase development it uses a lot of industrial equipment that helps a lot and makes work easier. As a result, a noisy work environment arises which can have a negative impact on workers. Preliminary studies show the factory noise level is 93,9 dB and there are still workers who do not use ear protection.

Research purposes. The purpose of this study was to determine the relationship between the level of knowledge about the dangers of noise and the adherence to the use of ear protection for textile factory workers in the weaving unit of PT. Pandatex Magelang.
Research methods. This research is a non-experimental analytic descriptive study with a cross-sectional view. The target of this research is the textile factory workers of PT. Pandatex weaving part because the weaving part has the highest noise intensity than other units. Respondents will be given a questionnaire about knowledge of the dangers of noise and compliance with the use of ear protection devices.

Results. The number of samples in this study were 66 people. With the results of the knowledge level score in the good category there is no, 17 people are enough, 49 people are lacking. Compliance with the use of ear protection equipment in the category of always using 28 people, often 9 people, sometimes 12 people, never 17 people. Correlation results with the Spearman test obtained p = 0,587 (p > 0,05).

Conclusion.  There is no relationship between the level of knowledge about the dangers of noise and the compliance with the use of ear protection devices.
