Changing lamp type and position to improve lighting quality

Abstract

This study investigates the lighting quality on the production floor in a cigarette paper industry by measuring illumination level and luminance. Cigarette paper inspection is performed manually by operators, and the criteria of defects are the cigarette paper has a hole, is rough and dirty. Operators complain that the room is pretty dark, which makes them unable to see clearly the cigarette paper defect. The government of Indonesia Health Ministerial Decree No 1405 The Year 2002 states that illumination level for continuous manual labor is 200 lux. Illumination level is measured for four days at 08.00, 10.00, 12.30, and 14.00 o’clock with 4 in 1 environmental meter. From the measurement result, it is found that using 7 LED lamps of 60 Watts can produce average illumination level of 70 lux. Low illuminance is caused by illumination level that does not meet the need 0f 569.759 lumen. Alternatives that can be used to increase lumen number are changing lamp type and position. One of the possibilities is using 24 LED of 138 Watts set 5.7 meters apart from one another can meet this demand. Another is using 5 LED of 150 Watts installed above the field of work.
