Abstrak: Noise Induced Hearing Loss (NIHL) merupakan kejadian yang cukup banyakterjadi pada industry manufaktur yang diakibatkan oleh pajanan kebisingan. PadaPT NGK Busi Indonesia, Jakarta terdapat bahaya kebisingan yang bersumber dari mesin dan peralatan kerja. Penelitian dilakukan secara Cross-sectional ataupotong lintang terhadap dosis pajanan bising harian dan keluhan gangguan pendengaran dengan melibatkan faktor perancu berupa usia, masa kerja, APT,merokok, hoby menembak, memakai head-set, menonton konser music rock,mengunjungi diskotik, riwayat penyakit telinga, obat oto/neurotoksik, danpenyakit degeneratif. Dengan metode pengukuran dosis pajanan bisisng harian dan pengisian kuisioner. Berdasarkan analisis hubungan dua variable hanyakebisaan merokok yang memiliki perbedaan yang nyata dengan keluhan gangguanpendengaran dengan nilai p-value < 0,05. Perlu ditingkatkan pelaksanaan HearingLoss Prevention Program berupa audit awal, identifikasi dan analisi sumberbising, peningkatan pengawasan penggunaan APT, audiometry berkala, program motivasi dan edukasi, dokumentasi dan audit program HLPP.
Kata Kunci: bising, keluhan gangguan pendengaran

Noise Induced Hearing Loss (NIHL) is the most event that happen in industrial ofmanufacture. This event mostly associated by noise exposure. Many noise hazardin PT. NGK Busi Indonesia, Jakarta that sourced from machinery and otherworking equipment. This study designed by cross-sectional method againts dailynoise dose exposure and hearing loss complaints that there are confoundingfactors such as working period, ear protective equipment, smoking, shootinghobby, listening music with head-set, watching rock concert, discotic, history ofhearing illness, neurotoxic drugs, and degenerative illness. This study was usingtools such as result of daily noise dose exposure measurement and fullfillmentquestionaire. According to relationship analysis of two variable there is onlyfactor of smoking habit that have strongly associated with hearing loss complaintswith p-value <0,05. This should be improvement of Hearing Loss PreventionProgram Implementation such as initial audit, identification and analize noisesource, supervise enhancement of ear protective equipment utilization, periodicalaudiometry, education and motivation programs, documentation and programaudit of hearing loss prevention program.

Abstrak: Kebisingan merupakan suatu bahaya fisik yang masih menjadi masalah di dunia industri. Pajanan bising intensitas tinggi dapat mempengaruhi fungsi pendengaran dan non pendengaran pekerja. PT. X merupakan suatu industri semen yang memiliki bahaya bising di area produksi, khususnya area raw mill, pembakaran, dan finish mill. Penelitian ini dilakukan untuk melihat gambaran pajanan bising, serta melihat gambaran fungsi pendengaran dan keluhan subjektif non pendengaran yang dirasakan oleh pekerja. Penelitian dilakukan dengan metode cross sectional, dengan subjek penelitian adalah seluruh pekerja patrol untuk area raw mill, pembakaran, dan finish mill sebanyak 20 orang.Hasil penelitian menunjukkan tingkat kebisingan area produksi (raw mill, pembakaran, dan finish mill) secara keseluruhan berkisar antara 75,4-108,2 dBA, pajanan bising yang diterima pekerja berkisar antara 81,5 ? 92,8 dBA. Terdapat 2 orang (10%) pekerja mengalami tuli ringan berdasarkan Permenakertrans No. 25 Tahun 2008 dari hasil rata-rata frekuensi 500, 1000, 2000 dan 4000 Hz, dan terdapat 2 orang (10%) mengalami NIHL berdasarkan frekuensi 4000 Hz. Faktor yang berkontribusi pada kejadian gangguan pendengaran pada pekerja antara lain, usia, masa kerja, penggunaan alat pelindung telinga yang tidak disiplin dan penggunaannya tidak tepat, riwayat pekerjaan dan perilaku merokok. Keluhan subjektif non pendengaran terkait bising yang paling banyak dirasakan oleh pekerja yaitu, perasaan tidak nyaman (85%).

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.The results showed that overall noise level at production area (raw mill, kiln and mill finish) ranged from 75.4 to 108.2 dBA, noise exposure to workers ranged from 81,5 ? 92,8 dBA. There are 2 workers (10%) suffering mild deafness from the calculation of the average frequency of 500, 1000, 2000 and 4000 Hz based on Permenakertrans No. 25 Tahun 2008, and there are two workers (10%) suffering NIHL based on frequency of 4000 Hz. Factors contributing to the incidence of hearing loss in workers are age, working period, undisciplined and improper use of ear protection, work history and smoking behavior. The majority subjective complaints of non auditory related noise perceived by workers is annoyance (85%).

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.
