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: Kesehatan dan keselamatan dalam bekerja merupakan hak bagi setiap pekerja. Namun, tidak dapat dipungkiri bahwa kondisi fisik lingkungan di tempat kerja yang biasa menjadi tempat para pekerja beraktivitas sehari-hari masih berpotensi menimbulkan banyak bahaya, Salah satunya adalah bahaya kebisingan. Kebisingan dapat terjadi di tempat kerja baik itu industri maupun non-industri. Pajanannya yang terjadi terus-menerus dan tidak sesuai dengan ketentuan dapat menimbulkan berbagai masalah kesehatan baik itu auditory maupun non-auditory. Oleh karena itu, penelitian ini ingin mengetahui hubungan tingkat pajanan kebisingan dengan keluhan subjektif (non-auditory) yang meliputi penilaian gangguan fisiologis, psikologis dan komunikasi pada 84 pekerja di area unit produksi pabrik tepung PT.X Cilegon, Banten. Hasil penelitian ini menunjukkan tidak adanya hubungan yang bermakna secara statistik antara masa kerja, usia, kebiasaan merokok, penggunaan alat pelindung telinga, kebiasaan menggunakan earphone, kebiasaan mendengarkan musik bersuara keras, dan juga pelatihan dengan gangguan fisiologis, psikologis dan komunikasi. Namun, angka kejadian gangguan fisiologis, psikologis dan komunikasi pada pekerja menunjukkan angka yang cukup tinggi yaitu sebanyak 26,2% pekerja mengalami gangguan fisiologis, 47,6% pekerja mengalami gangguan psikologis, dan sebanyak 48,8% pekerja mengalami gangguan komunikasi. Oleh karena itu, perusahaan tetap perlu menindaklanjuti terkait permasalahan kebisingan ini agar tidak menimbulkan risiko dan juga masalah kesehatan yang lebih besar kedepannya.

Health and safety at work are rights of every worker. However, it cannot be denied that the physical condition of the environment in the workplace which is used to be a place for workers to do their daily activities is still potential to cause many hazards, one of which is the danger of noise. Noise can occur in the workplace both industrial and non-industrial. Exposure that occurs continuously and not in accordance with the provisions can cause various health problems both auditory and non-auditory. Therefore, this study wants to find out the relationship between the level of noise exposure and subjective (non-auditory) complaints which include assessment of physiological, psychological and communication disorders of 84 workers in the production unit area of the flour mill PT.X Cilegon, Banten. The results of this study indicate that there is no statistically significant relationship between years of service, age, smoking habits, use of ear protection equipment, habit of using earphones, habit of listening to loud music, and also training with physiological, psychological and communication disorders. However, the incidence of physiological, psychological and communication disorders among workers showed a fairly high rate, namely as many as 26.2% of workers experiencing physiological disorders, 47.6% of workers experiencing psychological disorders, and as many as 48.8% of workers experiencing communication disorders. Therefore, companies still need to follow up related to this noise problem so as not to pose risks and also greater health problems in the future.
