Pengukuran Intensitas dan Pemetaan Kebisingan di Area Fatty Acid Plant PT. Permata Hijau Palm Oleo KIM II Mabar

Abstract

PT. Permata Hijau Palm Oleo KIM II Mabar is a processing plant derived from palm oil which produces fatty acids / fatty acids. In the process of processing PT. Permata Hijau Palm Oleo KIM II Mabar uses noise-generating machines. This study aims to determine the existing noise level and noise mapping and proposed noise control on the production floor. The method of collecting data is by observing the equivalent noise level calculation method (Leq) and noise mapping with software surfer. Data collection is carried out at 16 points on the production floor. The results of the study and the pattern of noise distribution showed high noise levels in several areas, namely point 5 (85.77 dB), point 6 (86.82 dB), point 7 (86.33 dB), point 8 (88.18 dB), point 10 (86.96 dB), point 13 (86.85 dB), point 14 (87.67 dB). The threshold value permitted under the Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia Number PER.13 / MEN / X / 2011 is 85 dB. Thus the company needs to conduct noise control such as the use of barriers, regular and scheduled inspection of machines to prevent and reduce the effects of such noise.
