Paparan Kebisingan Chainsaw terhadap Persepsi dan Tingkat Konsentrasi Pekerja pada Aktivitas Pemanenan Kayu

Abstract

Chainsaw use in timber harvesting generates high noise levels that may impact workers’ perception and concentration. This study measured chainsaw noise intensity and analyzed its effect on workers at PT Toba Pulp Lestari, Habinsaran Sector. A quantitative approach was used, including noise measurements, perception assessments using Likert scales, and concentration tests analyzed with the Wilcoxon Signed Rank Test. Results showed noise levels between 102.3 dB and 121.1 dB, exceeding the safe exposure limit of 85 dB. Experienced workers perceived the noise as less disturbing, while hearing protection significantly improved concentration performance. The study concludes that chainsaw noise affects both perception and concentration, and recommends consistent use of hearing protection to reduce risks and improve workplace safety.
