Effect Of Light Intensity On Eye Fatigue In Welding Students

The improper light intensity can cause eye fatigue in a person. Based on preliminary observation in the Technical Implementation Unit of Job Training (UPTPK) Singosari-Malang it was known that the light intensity in the welding room at UPTPK Singosari-Malang was ranging from 10125 lux to 10297 lux. According to the International Labor Organization (ILO) the ideal light intensity for metal work or welding is 200 lux. This study aimed to determine the effect of room light intensity on eye fatigue in the welding students at the Technical Implementation Unit of Job Training (UPTPK) Singosari-Malang. This research used the method of Quasi-experimental. Samples in this research were all the welding students at UPTPK Singosari-Malang and the sampling technique was Total sampling. Research data were statistically analyzed by using Mann-Whitney analysis. Based on the results it can be stated that there was a significant difference on the eye fatigue experienced by the welding students in accordance with the treatment of decreasing and increasing the light intensity of the room.
