Abstract
The purpose of this study is to determine whether the environmental conditions of the work environment in the
form of ambient temperature, humidity, and light intensity affect the energy expenditure of sealer machine
workers at PT. Mannasatria Kusumajaya Perkasa. The working environment of sealer machine workers was
very dependent on the weather conditions in the area, so there was no fixed temperature, humidity, and light
intensity. The analytical method in this study used analysis of variance (ANOVA), using a factorial experiment
with randomized block design. Each factor of temperature, humidity, and light intensity has two levels. These
three factors will be tested on four age groups of workers, namely workers aged 20-25 years old, 26-30 years
old, 31-35 years old, and 36-40 years old.
The results of the ANOVA test stated that there was an influence of humidity factor and the interaction of
temperature and humidity factors on the energy expenditure of workers. The LSD test on the humidity factor
stated that a humidity level of ≥71% caused a higher number of worker calories (223.250 kcal) than a humidity
level of 53.8-70% (205.625 kcal). The LSD test of the interaction of temperature and humidity factors
concluded that at a humidity level of ≥71%, a temperature of 29-32°C caused a higher average energy
expenditure of workers than at a temperature of 24-28.9°C. The level of reliability and accuracy of the results
of the analysis of variance in this study was 84.592%.
Keywords: energy expenditure, ANOVA, temperature, humidity, light intensity
