The Increased Blood Pressure Due to Effect of the Intensity of Noise on Workers in PT. Pindad (Persero) Turen

Abstract

Each job has a potential hazard that can cause work accidents or diseases, one of which is the noise hazard that can cause an increase in blood pressure. To reduce the hazards caused by noise, workers can use ear protector (Alat Pelindung Telinga / APT) such as earplug and earmuff. In the preliminary study at PT. Pindad (Persero) noise generated by one machine reaches 98 dB(A) and most workers do not use APT. This study aims to determine the effect of noise intensity and compliance using Ear Protective Tool (APT) at PT. Pindad (Persero). The research design used was analytic observational research using cross-sectional approach. The sample technique used purposive sampling.  Samples are employees of PT. Pindad (Persero) a number of 30 respondents in the tooling. The result of the research shows that noise variable significance for systole = 0,036 and 0,024 for diastole. Because Sig is both <α (0,05) it is concluded the effect of noise intensity on blood pressure. While the systol significance value of compliance variable = 0.714 and 0.370 for diastole. So there is no relationship between adherence to the use of Ear Protective Equipment (APT) with an increase in blood pressure. Exposure to high-intensity noise causes an increase in the hormone cortisol which causes a rise in blood pressure in workers after they are exposed to noise. To reduce this, other than the workers are required to use the Ear Protective Tool, there should be a schedule of safety control and medical check up as well as strict sanctions against workers who do not use Personal Protective Equipment.
