Analysis of Environmental Noise Levels and LTM10 Values at Sumbawa University of Technology and Their Compliance with the Threshold Limit Value

Analisis Tingkat Kebisingan dan Perhitungan LTM10 di Universitas Teknologi Sumbawa serta Evaluasinya terhadap Nilai Ambang Batas

Abstract

Environmental noise represents a form of physical pollution that may interfere with comfort and academic concentration in educational settings. This study aims to analyze environmental noise levels at Sumbawa University of Technology using the 10-minute equivalent continuous sound level (LTM₁₀) and to assess their compliance with the applicable Threshold Limit Value (TLV). Measurements were conducted at four strategic campus locations: the Rectorate Building frontage, the Faculty of Environmental and Mineral Technology (FTLM) roundabout, the Integrated Laboratory (ITL) intersection, and the SIKIM intersection. Each site was monitored for 10 minutes using a Sound Level Meter (SLM). The recorded LTM₁₀ values ranged from 57.49 to 77.54 dB(A), with the highest level observed at the ITL intersection and the lowest at the FTLM roundabout. All locations exceeded the 55 dB(A) noise limit for educational areas as stipulated in Decree of the Minister of Environment No. 48 of 1996, although they remained below the occupational exposure limit of 82 dB(A). These results indicate that campus noise levels have surpassed acceptable acoustic comfort standards, underscoring the need for effective noise mitigation strategies to enhance the quality of the learning environment.
