Noise Risk Assessment at Air Separation Plant PT. X Surabaya (Nitrogen, Oxygen, and Argon Plant)

Abstract

Background : Noise was one of the dangerous factors at a workplace which causes various effects on workers. Purpose : The purpose of this research was to described the activity stages, identified the noise danger, and assessed the risk and its level at Air Separation Plant of PT. X. Methods : This research was a descriptive research with a cross sectional approach. The object of the research was the noise danger potential and the noise risk level assessment at Air Separation Plant of PT. X. Results : The result of this research showed that there were 12 identified noise danger points. These results consisted of 5 (42 %) noise risks with low category, 2 (16 %) with middle category, and another 5 (42 %) with high category. The highest noise intensity measurement result was found on Recycle Nitrogen Compressor (RNC) machine, which was 116,5 dBA. Conclusion : Based on this data, it can be concluded that there were 12 identified noise danger points and the highest noise intensity measurement result was found on Recycle Nitrogen Compressor (RNC) machine, which was 116,5 dBA. It is suggested for the related company to execute controls mostly in diminishing the noise sources.

Noise Exposure and Hearing Loss on Field Operator Compressor House Area

“…Sebagai contoh industri pupuk di Aceh memiliki tingkat kebisingan di wilayah compressor house area yang telah melebihi standar yaitu sebesar 97dB (4). Selain itu pengukuran kebisingan di compressor house amonia pada industri pupuk di Kalimantan menunjukkan hasil sebesar 106,4dB di wilayah compressor house amonia I, sebesar 104,35dB di wilayah compressor house amonia II, sebesar 101,48dB di wilayah compressor house amonia III dan sebesar 94,83dB di wilayah compressor house amonia IV (5).…”
