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.

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: Bising di tempat kerja dapat menimbulkan dampak terhadap sistem auditory maupun sistem non-auditory. PT X merupakan industri manufaktur yang mempunyai proses produksi yang menghasilkan bising. Penelitian ini bertujuan untuk mengetahui hubungan dosis pajanan bising harian, usia, masa kerja, dan pemakaian alat pelindung telinga (APT) dengan gangguan non-auditory. Pengumpulan data dilakukan dengan pengukuran dosis pajanan bising harian secara langsung di lapangan dan gangguan non-auditory melalui wawancara terstruktur. Hasil pengukuran dosis pajanan bising harian diketahui seluruh unit kerja yang diukur berada diatas NAB (Nilai Ambang Batas). Di samping itu, hasil pengukuran gangguan non-auditory dari 52 responden diperoleh tingkat gangguan non-auditory berat sebanyak 59,6% dan gangguan non-auditory ringan sebanyak 40,4%. Analisis rata-rata dosis pajanan bising harian dengan gangguan non-auditory menggunakan uji t diketahui bahwa terdapat perbedaan yang signifikan antara pekerja yang mengalami tingkat gangguan non-auditory. Sedangkan analisis antara variabel usia, masa kerja, dan pemakaian APT dengan gangguan non-auditory diperoleh hubungan yang tidak signifikan. Berdasarkan hasil penelitian dapat disimpulkan gangguan non-auditory yang dialami oleh pekerja lebih disebabkan oleh dosis pajanan bising harian. Rekomendasi yang diberikan yaitu mengendalikan gangguan non-auditory dengan menurunkan dosis pajanan bising harian yang ada hingga di bawah NAB.

Occupational Noise can cause either auditory system or non-auditory system disorder. PT X is a manufacturing industry which has production process that produces noise. The purpose of this study is to observe the relationship between daily noise exposure dose, age, working time and utilization of hearing protection to nonauditory disorders. Data collection was done by direct measurement for daily noise exposure dose and structural interview for non-auditory disorders. The result from measurement of daily noise exposure dose in all working units showed the value above the Threshold Limit Value (TLV). In the other hand, the result for nonauditory disorder measurement showed 59.6% of 52 respondents suffered severe nonauditory disorders and 40.4% suffered mild non-auditory disorders. Analysis using TTest resulted in significant difference on means value of daily noise exposure dose between non-auditory disorders levels. Furthermore, analysis of age, working time, and utilization of hearing protection to non-auditory disorder resulted in insignificant relationship. Based on the result of the study, it could be concluded that non-auditory disorder suffered by workers was mostly caused by daily noise exposure dose. Hence, the recommendation to control the non-auditory disorders is to reduce daily noise exposure dose until lower than TLV.

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%).
