Abstract

Farmers generally use rice mills as a tool to separate rice husks. The main driver of the rice milling machine is a diesel engine, which makes a lot of noise. Noise intensity that exceeds the threshold value can cause health problems for workers in the form of increased blood pressure. This study aimed to analyze the effect of noise intensity in the work environment on improving blood pressure. This research is an analytical observational study using a cross-sectional approach. The total population in this study was 40 workers. Proportionate Stratified Random Sampling is the sampling technique in this research, with a sample size of 37 respondents. Data collection techniques include interviews, measuring noise intensity, and measuring blood pressure. Data analysis used wilcoxon test and Spearman correlation test, where the test criteria for H0 are accepted if p > 0.05 and H0 is rejected at p < 0.05. Based on the results of research conducted at a rice mill in Driyorejo District, Gresik Regency, it can be concluded that there is a difference between blood pressure (systolic and diastolic) before and after work. There is an influence between noise intensity, work period, age, smoking habits, and hereditary history. There was no effect between exposure time and increased blood pressure.

Abstract

Workplace noise is one of the physical factors that is often overlooked, although long-term exposure can have serious impacts on cardiovascular health. In workers exposed to noise, blood pressure and heart rate often increase as the body's response to physical stress. This physiological mechanism triggered by prolonged noise can result in an increased risk of cardiovascular disorders, including hypertension and heart rhythm disorders. The purpose of this study was to analyze the effect of noise on increasing blood pressure and heart rate in workers in the workshop area, especially the dynotest room. This type of research is observational with a cross-sectional research design. Conducted in December - May 2024 with the object of research on workers exposed to noise in the workshop area, especially the dynotest room. Data were analyzed using the Logistic Regression test. The total sample was 40 workers in the workshop area and dynotest room. Data were collected from observations, room noise measurements, blood pressure, and heart rate. Based on the results of the study, the average results for the dynotest area were 83.5 dBA, while for the dynotest room, the average results were 117.8 dBA. The results of statistical tests of blood pressure and pulse rate in workers obtained a sig value = 0.001. These results indicate an increase in blood pressure and pulse rate due to noise. It is recommended for the Company to monitor workers to find out the disorders caused by noise.
