Work environment is one of the important factors that affects the workers’ body condition in work. The worker’s condition will affect to their productivity level. This study aims to see whether heat exposure has an effect to workers’ health and the productivity of the workers at PT X in Glass Division. The workers’ health parameter measured are body temperature, systolic blood pressure, diastolic blood pressure and pulse rate. This study was performed on 24 respondents as a sample, which are the workers of PT X in Glass Division consisted of 16 workers in machine unit and 8 workers in manual unit. Measurement of heat working environments was done using WBGT (Wet Bulb Globe Temperature) method in accordance with SNI-16-7061-2004, which included wet temperature, dry temperature, radiant temperature, humidity, and air velocity. Measurement of the worker’s health was done using digital infrared thermometer and digital sphygmomanometer. WBGT measurement results obtained in machine unit and manual unit indicated that all of the results have passed the quality standard based on Permenaker No. 13/2011, which is 28 °C for moderate workload for a total of 8 hours and 75-100% is used for working. The results of worker’s health measurement in machine unit showed significant results that heat exposure affected body temperature (p-value 0,005<0,05), pulse rate (p-value 0,045<0,05) and work productivity (p-value 0,004<0,05), while the measurement in manual unit also showed significant results that heat exposure affected body temperature (p-value 0.017<0,05) and pulse rate (p-value 0,037<0,05), but does not affected work productivity (p-value 0,439<0,05). From this study showed in machine unit there is an increase of body temperature and pulse rate are greater between before work and after work. This is closely related to the results of air velocity measurements on machine unit is smaller than manual unit, which indicates that in machine unit has no good air circulation, that gives impact to the productivity of work in PT X, namely the productivity of workers in manual unit is higher than machine unit.
