Evaluation of the Effect of Thermal Comfort in PMV-Method Classrooms on Teacher Work Stress Levels in the Dry Tropics (Study at Beru Elementary School, Sikka Regency)

This study aims to evaluate the effect of classroom thermal comfort on the level of teacher work stress in a dry tropical region (Study at SDI Beru, Sikka Regency), using the PMV (Predicted Mean Vote) method. Thermal comfort, which includes temperature, humidity, and air flow, is very important to create a conducive learning environment. Temperature and humidity measurement data were collected using temperature and humidity measuring devices model GSP-6 and RC-4HC for a certain period. In addition to using PMV, this study also used Regression and Correlation data analysis using SPSS. The sample used was a saturated sample. The results obtained in this study indicate that based on the PMV calculation, it was obtained that the temperature and humidity in the classroom varied and often exceeded the ideal comfort range. This condition can increase the level of teacher work stress and reduce productivity, this is in line with the results obtained from the SPSS program obtained validity and reliability testing using SPSS software there are 50 valid and reliable statements, the results of the analysis show that there is a significant linear relationship between work stress and thermal comfort (F Linearity = 30.454; Sig Linearity = .000). Based on these calculations, it can be seen that the regression coefficient value of the thermal comfort variable (X1) is 0.498 with a positive sign at sig 0.000 which is smaller than 0.05, namely 0.000 0.05. The regression coefficient value of the thermal comfort variable (X1) of 0.498 indicates that there is a positive relationship between thermal comfort and teacher work stress. This means that every one unit increase in thermal comfort will be associated with a 0.498 unit increase in the measured variable (teacher work stress). The significance value (p-value) of 0.000 is smaller than 0.05 (0.000 0.05). This shows that the results are statistically significant. In other words, there is strong evidence to state that thermal comfort has an effect on teacher work stress. So it can be interpreted that thermal comfort has a positive effect on teacher work stress.
