Noise is a physical hazard which still a problem in the industrialized world. Exposure to high intensity of noise can affect hearing function and non-hearing function. PT. X is a cement industry possessing the noise hazard in the production area, especially at raw mill, kiln and finish mill area. The purpose of this study is to provide an overview of the noise exposure, as well as the auditory function and subjective complaints of non auditory perceived by workers. This study was conducted by cross sectional method, and the subjects of this study were all patroler workers for raw mill, kiln and mill finish area, which all 20 subjects participated in the study.
Gangguan pendengaran pada pekerja minyak dan gas bumi merupakan penyakit akibat kerja utama sampai saat ini. Gangguan pendengaran antara lain disebabkan oleh pajanan bahaya fisik berupa bising. Penelitian ini bertujuan untuk mengetahui gambaran pajanan bising dan fungsi pendengaran pada pekerja di Platform KE-5 Kodeco Energy. Jenis penelitian adalah penelitian observasional dengan rancangan cross sectional yaitu meneliti sekaligus variabel independen, variabel dependen, dan vaiabel perancu pada waktu yang bersamaan. Analisis data adalah tabel dengan menggunakan analisis data univariat.
Didapatkan gambaran tingkat bising di platform KE-5 yang melebihi NAB yaitu pada rentang 81 dBA sampai dengan 103 dBA, dan tingkat pajanan bising di platform KE-5 melebihi NAB dengan dosis pajanan bising yang diterima pekerja terdapat di bawah NAB yaitu pada rentang 70,4 dBA sampai dengan 77,5 dBA, serta didapatkan tujuh pekerja dengan gangguan fungsi pendengaran.
Hearing impairment in oil and gas workers is the main occupational diseases. Hearing impairment, among others caused by exposure to physical hazards of noise. This study aims to know the description of noise exposure and hearing impairment in workers at KE-5 Kodeco Energy Platform. The type of research is observational with cross sectional design which examined as well as the independent variable, dependent variable, and confounding variable at the same time.
Obtained noise level at KE-5 Platform which exceeds the TLV is in the range of 81 dBA to 103 dBA, noise dose of exposure that received by workers are still under the TLV is still in range of 70.4 dBA to 77.5 dBA, the level of noise exposure in KE-5 Platform exceeds the TLV by noise dose exposure that received by workers less than the TLV and obtained seven workers with impaired hearing function.
