Analisis Kualitas Udara Partikulat PM 2,5, PM 10, dan Pencahayaan di Tempat Pengolahan Sampah Terpadu (TPST) USU

Abstract

The increasing consumption patterns of society have led to a significant rise in waste generation, which has the potential to cause various environmental impacts, one of which is air pollution. The Integrated Waste Treatment Facility of Universitas Sumatera Utara (TPST USU), as a waste management facility based on circular economy principles, carries out operational activities that may generate air pollutants and consequently affect workers’ health. This study aims to analyze air quality in terms of PM₂.₅ and PM₁₀ concentrations and lighting conditions under prevailing meteorological conditions, to examine pollutant dispersion patterns using ANSYS Workbench software and the Gaussian dispersion equation, and to formulate recommendations to minimize the impacts of air pollution on workers at TPST USU. Measurements were conducted at the entrance gate area and the shredding area. The results indicate that the measured concentrations of PM₂.₅ and PM₁₀ in the shredding area exceeded the ambient air quality standards, while concentrations at the entrance gate and receptor locations remained below the regulatory limits as stipulated in Government Regulation Number 22 of 2021. Lighting levels in all work areas met the permissible exposure limits in accordance with the provisions of Minister of Manpower Regulation Number 5 of 2018. Based on these findings, several mitigation measures are recommended to reduce the impact of air pollution on workers, including emission control at the pollution source, regulation of machine operating hours, improvement of lighting distribution in work areas, and the use of appropriate personal protective equipment.
