| dc.description.abstract | As time goes by, cases of environmental pollution are increasing. Environmental pollution can take the form of physical, chemical and biological pollution. Physical pollution is pollution that is rarely touched, one of which is noise. Noise can be generated from operating industrial equipment. Noise that exceeds the threshold can have a bad influence on workers, namely hypertension. Based on a preliminary survey, it was found that 6 out of 10 welding workshop workers on Jalan Mahkamah, Medan Kota Subdistrict had blood pressure ≥ 140/90 mmHg due to exposure to noise > 85 dB every day. The aim of this research was to determine the relationship between noise and hypertension in welding workshop workers on Jalan Mahkamah, Medan Kota Subdistrict. This research uses analytical research with a cross sectional approach. The sample in this study amounted to 32 people and the sampling technique was carried out using purposive sampling with exclusion criteria, namely having a history of hypertension, diabetes mellitus and heart disease. The results of the study in univariate analysis showed that workers experienced hypertension (53.1%), aged ≤ 35 years (62.5%), exposure time > 8 hours (62.5%), work period ≤ 5 years (65.6%), smoking (65.6%), not consuming alcohol (59.6%). From the chi square statistical test that was carried out, there were variables that were related, namely noise (p=0.014) and length of service (p=0.002). The conclusion of this research is that there is a relationship between noise and the incidence of hypertension in welding workshop workers on Jalan Mahkamah, Medan Kota Subdistrict. The advice given to welding workshop workers is to get used to using PPE in the form of ear plugs, carry out routine health checks, and reduce habits that can increase blood pressure | en_US |
