Description	Journal: Iop Conference Series: Materials Science and Engineering This study observes work thoroughness of sorting operators in quality control station at drinking bottle industry. Operators sort the bottles manually using naked eyes to decide whether the bottles have some defects or not. Dirty bottles, cracked, chipped or have water volume that is different from other bottles will be taken by operators. The low light intensity in quality control station causes high numbers of defect bottles to pass the inspection. The standard of Government of Indonesia Health Ministerial Decree No 1405 The Year 2002 that work performed continuously needs 200 lux of lighting. Illuminance level measurement is conducted for five days at 09.00, 11.00, 13.00, and 15.00 o’clock using lux meter on four measurement points using a grid of 1m x 1m. In this study, the average light intensity in quality control station 1 and 2 is 59.30 lux and 52.15 lux. The number of defective products that pass the inspection in a quality control station for 5 days of observation is 2,676 bottles or 55.47% from the total defect products, while the number allowed by the company is only 5%. The correlation between illumination factor in quality control station 1 and defect products that pass the inspection is calculated moment Pearson correlation product and the results are ŷ=292,885-1,317x and r=-0,3147, while in quality control station 2 the results are ŷ=524,077-4,919x and r=-0,6329. The higher illumination level, the lower the number of defective products that pass the inspection, which means operators’ work thoroughness improve.
