The study of thermal comfort and noise level in battery plate factory

Abstract

The successful of manufacturing factories in industry is highly dependent on a productivity of their employees especially operators. It was identified that comfort and noise level can reduce the productivity of their workers. This study is to determine the level of thermal and noise comfort in the battery plate factory. This study was conducted in three days and location of the study is at battery plate factory in Semenyih, Selangor, Malaysia. The scope of study is focused at plate manufacturing area where the employee estimated 40 persons. The thermal comfort level can be determined by calculating PMV and PPD. This study involved six factors of comfort which is air temperature, average radiant temperature, air velocity, relative humidity, metabolic rate and clothes insulation. Then the study of noise level was conducted by determining LAeq, T, Lmax and Lmin. To carry out this study, Babuc-A equipment was used. The analysis shows the area of the manufacturing battery plate having a discomfort condition and PMV result is between 1.5 until 3, Air temperature on the other hand is between 27,4??C- 37,8??C while relative humidity is between range 35.35% -92.1% and air velocity 0 m/s- 1.28 m/s, Meanwhile the LAeq,T value in the factory is varied from 68 to 80 dB.
