Abstrak:
Tingkat kebisingan di Instalasi Pengolahan Air (IPA) cukup tinggi. Meningkatnya kebutuhan air bersih seiring dengan bertambahnya populasi penduduk, membuat Perusahaan Daerah Air Minum (PDAM) dituntut untuk meningkatkan kapasitas produksi. Terdapat alat-alat dan proses produksi yang memiliki karakteristik berbeda dibanding jenis industri lain. Terdapat 306 PDAM di seluruh Indonesia, potensi jumlah pekerja yang terpajan bising sangat besar, maka perlu diteliti lebih lanjut mengenai hubungan karakteristik bising serta faktor-faktor determinannya terhadap gangguan pendengaran pada pekerja di PDAM untuk memperoleh bentuk pengendalian yang paling tepat. Penelitian ini menggunakan desain studi potong lintang. Tahapan penelitian ini yaitu mengukur tingkat kebisingan serta memberikan kuesioner sebagai data primer, menganalisis hasil audiometri pekerja sebagai data sekunder dan menggunakan uji statistika Chi Square dan analisis multi determinan untuk mengetahui hubungan di antara variabel independen dan dependen. Hasil penelitian diperoleh bahwa sumber bising di instalasi pengolahan air adalah pompa, exhaust fan, kompresor, blower, vacuum dan terjunan air. Sebanyak 84.4% pekerja di area produksi terpajan bising > 85 dBA. Sebanyak 15.6% pekerja mengalami gangguan pendengaran. Diperoleh kesimpulan bahwa pekerja yang terpajan bising di atas 85 dBA yang memiliki frekuensi bising dominan > 2000 Hz dapat menyebabkan terjadinya gangguan fungsi pendengaran dan diperparah apabila pekerja berusia > 40 tahun dan memiliki masa kerja > 14 tahun. Kata kunci: Kebisingan, PDAM, Gangguan pendengaran, Frekuensi bising
Noise level in Water Treatment Plant (WTP) is high enough. Increasing the need for clean water in line with the increasing population, making the Water Supply Company (PDAM) is required to increase production capacity. There are machines and production processes that have different characteristics than other types of industries. There are 306 PDAMs throughout Indonesia, the potential number of workers exposed to noise is very large, it is necessary to further investigate the relationship between noise characteristics and its determinants to hearing loss to PDAM workers to obtain the most appropriate form of control. This study used a cross sectional study design. The stages of this study are to measure the noise level and provide questionnaires as primary data, analyzing the worker audiometric results as secondary data and using Chi Square statistical test and multi determinant analysis to find out the relationship between independent and dependent variables. The results obtained that the source of noise in water treatment plants are pumps, exhaust fan, compressor, blower, vacuum and waterfall. About 84.4% of workers in the production area exposed to noise > 85 dBA. About 15.6% of workers have hearing loss. It is concluded that exposure workers over 85 dBA with dominant noise frequency > 2000 Hz can cause hearing impairment and aggravate if workers are > 40 years old and have a working life > 14 years. Key words: Noise, Water supply company, Hearing loss, Noise frequency

Abstrak:
Semua kegiatan manajemen risiko selalu memfokuskan aktifitasnya untuk mengurangi atau meminimalkan risiko. Banyak metode analisis risiko yang dipergunakan pada saat menerapkan manajemen risiko dalam aktifitas yang berhubungan dengan kerja Analisis lapisan pelindung (Layer of Protection Analysis - LOPA) adalah salah satu metode analisis risiko semi-kuantitatif dalam manajemen risiko yang ditujukan untuk mengurangi atau mereduksi risiko dengan jalan menyusun lapisan pelindung yang akan dipergunakan untuk menurunkan tingkat risiko yang ada. LOPA sangat ditentukan oleh tiga faktor utama, yaitu : Penentuan Skenario, Pemilihan Initiating Event, dan Seleksi Independent Protection Layer. PT X dan PT Y merupakan salah satu industi proses kimia yang dipilih untuk diteliti hasil studi LOPA mereka. Latar belakang pemilihan PT X dan PT Y ini karena kedua perusahaan tersebut memiliki karakteristik yang mirip dengan terminal BBM yang terbakar dalam tragedi Buncefield Hasil penelitian didapatkan bahwa reduksi risiko kedua perusahaan berbeda, meski skenario dan Independent Layer Protection (IPL) yang terlibat identik. Perbedaan ini karena kedua perusahaan memiliki aturan program perawatan IPL yang berbeda. PT X memiliki aturan program perawatan yang lebih ketat dibandingkan PT Y. Semua program yang ditujukan untuk menjaga kehandanlan akan menaikkan nilai reduksi risiko dengan faktor 10. Validasi dan ITPM (Inspection, Testing dan Preventive Maintenance) merupakan salah satu langkah yang bisa dipergunakan untuk memperbesar Reduksi Risiko yang terjadi pada hasil studi LOPA.
All risk management activities always focus on activities to reduce or minimize risks. Many risk analysis methods are used when applying risk management in work-related activities Layer of Protection Analysis (LOPA) analysis is one of the semi-quantitative risk analysis methods in risk management aimed at reducing or reducing risk by formulating a protective layer that will be used to reduce the risk level. LOPA is determined by three main factors, namely: Scenario Determination, Initiating Event Selection, and Independent Protection Layer Selection. PT X and PT Y are one of the chemical process industries selected for their LOPA study. The background of the election of PT X and PT Y is because both companies have similar characteristics to the burning fuel terminal in Buncefield tragedy The results showed that the risk reduction of both companies was different, although the scenario and the Independent Layer Protection (IPL) involved were identical. This difference is because both companies have different rules of IPL treatment program. PT X has a more stringent treatment program regulation than PT Y. All programs aimed at maintaining customs will increase the risk reduction value by a factor of 10. Validation and ITPM (Inspection, Testing and Preventive Maintenance) is one of the steps that can be used to enlarge the Risk Reduction of LOPA study results.
