Abstract
Project x is an apartment development activities in Tangerang which in the process of construction resulted in the occurrence of noise. Noise is one of the incidents that can be lead to health problems for the surrounding community. Therefore, this research aims to know the spread of noise, the amount of noise reduction that can be reduced by using a hearing protective device and workers' perceptions of noise against hearing loss. The method used is the contour zone. Data used is the result of noise measurement Project x in the daytime and nighttime conditions. The result obtained is the noise level in the project work area during the daytime in area 1, 2 and 3 with a distance of 2 meters are 97.1 dB, 94.4 dB, 93.9 dB, and length of 4 meters are 94.4 dB, 91.5 dB, 93.0 dB and night measurements at a distance of 2 meters are 102.2 dB, 100.1 dB, 96.5 dB, and length of 4 meters are 94.7 dB, 94.7 dB, 97.4 dB. The calculation of day and night above exceeds the noise threshold value set by the Ministry of Labor which is 85 dB. The perception of the worker with the noise disturbances that occur at The Yukata Project. Using hearing protection devices will reduce the noises, but at nighttime conditions in areas 1 and 2 at a distance of 4 meters, the noise level still exceeds the noise threshold value which has been determined by the ministry of labor.
