RESPONDENT S CHARACTERISTIC AND NOISE INTENSITY AS PREDICTING FACTORS OF NOISE INDUCED HEARING LOSS

Pendahuluan: Gangguan pendengaran tipe sensorineural yang disebabkan oleh pajanan bising yang cukup keras dalam jangka waktu yang lama dikenal dengan Ganguan pendengaran akibat bising. PT. Multikarya Asia Pasific Raya (PT. MKAPR) merupakan perusahaan yang menyediakan produk dan layanan untuk industri minyak dan gas di Indonesia. Berdasarkan hasil medical check up, pekerja workshop di PT MKAPR memiliki risiko mengalami gangguan pendengaran akibat bising. Pada area Workshop Lodan-9 diketahui memiliki tingkat kebisingan yang berbeda, yaitu 88-91 dB pada area fabrikasi, pompa dan engineering, serta 90-102 dB di function test area. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang berhubungan dengan kejadian gangguan pendengaran akibat bising. Metode: Penelitian ini menggunakan desain penelitian kasus-kontrol. Populasi kasus pada penelitian ini sebanyak 26 orang dan populasi kontrol sebanyak 48 orang. Sampel kasus dalam penelitian ini sebanyak 26 orang) dan sampel kontrol sebanyak 26 orang. Teknik pengambilan sampel dengan teknik purposive. Data dikumpulkan dengan menggunakan kuesioner, kemudian dianalisa dengan menggunakan uji chi kuadrat. Hasil: Ada hubungan yang signifikan antara intensitas kebisingan (Pvalue : 0,035 ; OR : 4,714 ; 95% CI : 1,266-17.561) dan masa kerja (Pvalue : 0,029 ; OR 5,622 ; 95% CI : 1,342-23,55) dengan kejadian gangguan pendengaran akibat bising. Sedangkan usia (Pvalue : 1 ; OR : 1,547, 95% CI : 0,336-2,976) dan kebiasaan merokok (Pvalue : 0,465 ; OR : 0,435; 95% CI : 0,096-1,168) tidak memiliki hubungan dengan kejadian gangguan pendengaran akibat bising. Simpulan: Intensitas kebisingan dan masa kerja merupakan penyebab pekerja mengalami gangguan pendengaran akibat bising. Semakin lama pekerja bekerja dengan intensitas kebisingan yang tinggi, maka semakin besar kemungkinan pekerja mengalami gangguan pendengaran akibat bising.


Alt. Description

Introduction: Sensorineural hearing loss caused by loud noise exposure for a long time is known as the risk of experiencing Noise-Induced Hearing Loss. PT. Multi Karya Asia Pacific Raya (PT. MKAPR) is a company that provides products and services to the oil and gas industry in Indonesia. Based on its medical check-up, workshop workers at PT MKAPR have the risk of experiencing Noise-Induced Hearing Loss. The Lodan-9 Workshop area was known to have different noise levels, 88-91 dB in the fabrication, pump and engineering areas, and 90-102 dB in the function test area. The purpose of this study was to identify predicting factors of Noise-Induced Hearing Loss at PT. MKAPR. Method: This study used a case-control design. The population in this study were 26 cases and 48 control. Sample size in this study consisted of 26 cases and 26 control. We used a purposive technique sampling. Data were collected through questionnaire, and then were analyzed by using Chi-Square Test. Result: There were association between noise intensity (P-value: 0.035 OR: 4.714; 95% CI: 1.266-17.561), and work period (P-value: 0.029; OR 5.622; 95% CI: 1.342-23.55) with the incidence of Noise-Induced Hearing Loss. Meanwhile age of workers (P-value: 1; OR: 1.547; 95% CI: 0.336-2.976) and smoking habits (P-value: 0.465; OR: 0.435; 95% CI: 0.096-1.168) have no relationship with the incidence of NoiseInduced Hearing Loss. Conclusion: Noise intensity and work period were predictors of Noise-Induced Hearing Loss on PT.MKAPR� workers. The longer the workers work in high noise intensity area, the more they are at risk of experiencing Noise-Induced Hearing Loss.
