Ambient Air Quality And Noise Analysis In Office Area: A Descriptive Measurement Study Single Point (Outdoor) In Parepare City

Abstract

Ambient air quality and environmental noise are important determinants of occupational health, work comfort, and employee productivity, particularly in office environments where daily activities are continuously conducted. Poor ambient air quality and excessive noise exposure may increase the risk of respiratory disorders, fatigue, and reduced work concentration. Therefore, periodic monitoring of air quality parameters in office areas is essential to ensure a healthy working environment. This study aims to analyze the condition of ambient air quality and noise levels in an office area of Parepare City based on physical and chemical air parameters.

This research employed a quantitative descriptive approach using a single-point outdoor measurement method. Data collection was conducted on November 20, 2025. The parameters measured included air temperature, relative humidity, wind speed, sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), particulate matter (PM₁₀), and noise levels. Measurement instruments consisted of a Sound Level Meter, thermohygrometer, anemometer, and an air quality monitoring device.

The results showed that the measured noise level was 64.46 dB(A), air temperature was 30°C, relative humidity was 76.8%, SO₂ concentration was 262 µg/Nm³, PM₁₀ concentration was 28 µg/Nm³, while NO₂ and CO were not detected. All measured air pollutant parameters were below the ambient air quality standards stipulated in South Sulawesi Governor Regulation Number 69 of 2010. However, physical parameters such as temperature and humidity indicated less optimal comfort conditions for office environments. This study provides baseline information on ambient air quality in office areas and may serve as a reference for environmental monitoring and air quality management to support sustainable occupational health.
