ABSTRAK UPAVA PENANGGULANGAN DAMPAK KEBISINGAN TERHADAP PENDENGARAN PEKERJA DENGAN BASIS PEMETAAN KEBISINGAN (NOISE MAPPING) DI MANUFACTUlUNG WORKSHPO PT.X DJ MEDAN Imelda Husdiani Mahasiswa Program Studi Magister Kesehatan Kerja Penelitian ini bertujuan untuk: 1) Identifikasi dan Evaluasi kebisingan dilingkungan kerja dengan membuat Noise Mapping; 2) Mengetahui Noise Induced Hearing Loss (NII'IL) pada pekerja dengan pemeriksaan Audiometri; 3) Merekomedasikan upaya pengendalian kebisingan berdasarkan Noise Mapping yang dibuat, Rancangan penelitian ini merupakan rangcangan diskriptif menggunakan metode survey dengan pendekatan cross sectional. Pengambilan data dilakukan dengan melakukan pengukuran dan kuesioner, Analisis data dilakukan dengan program computer SPSS Versi 11, menggunakan analisa bivariat non Parametric dengan Kendall Tau untuk mengetahui hubungan antara intensitas kebisingan dan dosis bising terhadap hasil Audiogram pekerja yaitu Noise Induced Hearing Loss. Lokasi penelitian ini di Unit Manufacturing Workshop PT. X di Medan, Hasil penelitian disimpulkan bahwa :1) Daerah Workshop Manufacturing PT X memiliki tingkat intensitas kebisingan 75% melebihi Nilai Ambang Batas; 2)Pekerja mendapatkan dosis bising berlebih adalah 85%; 3)Hasil tes Audiometri mendapatkan bahwa 40% pekerja mengalarni NIHL. Upaya pengendalian kebisingan yang direkomendasikan berdasarkan Noise Mapping yang dibuat adalah: 1)Pemakaian Alat Pelindungan Pendengaran berupa earplug pada lokasi yang melebihi Nilai Ambang Batas, 2)Pengendalian secara rnedis berupa pemeriksaan Audiometri secara berkala; 3)Pengendalian secara teknis berupa pemakain penempatkan Sound Barrier dan melakukan perawatan mesin secara berkala, Kata kunci : Tingkat Intensitas kebisingan, dosis bising,nihl Imelda Husdiani : Upaya penganggulangan dampak kebisingan terhadap pendengaran..., 2005.

ABSTRACT EFFORT TO OVER COME IMPACT OF NOISE DUE TO WORKERS HEARING BASED ON NOISE MAPPING IN MANUFACTURING WORKSHOP PT.XMEDAN IMELDA HUSDIANI Student ofpost-graduate Occupational Health Program This research had a purpose to: I) Identify and evaluate noise on working environment by making Noise Mapping. 2) Know Noise Induced Hearing Loss (NIHL) on worker using Audiometric test. 3) Recommend Noise Control based on Noise Mapping. The Design of this research was descriptive design using survey method with cross sectional approach. Data was collected using measurement devices and questioner. Data was analyzed using software computer program SPSS version 11, using statistical test that is bivariat non parametric analysis with Kendall Tau to find out the relation between Noise level, Noise Dose and NIHL. This research was located in the Manufacturing Workshop Unit PTX Medan. Result ofthe research were concluded that: I)Workshop Manufacturing Area at PTX had Noise level 75% exceeded the limit. 2) The worker received noise over dose was 85%. 3) Audiometric test result showed that 40% ofworker experiencing NIHL. Recommended Noise Control based on Noise Mapping are : 1) The use of hearing protector device that is Earplug in Area with Over the limit noise Level. 2 ) Medical noise control with Audiometric test Periodically. 3) Technical noise control with the use of Sound Barrier and maintain machines periodically Key words: Noise Level, Noise Dose, NIHL Imelda Husdiani : Upaya penganggulangan dampak kebisingan terhadap pendengaran..., 2005. ii - I
