Abstract
The Tlekung Final Disposal Site (TPA) in Batu City operates incinerator units to reduce waste volume through combustion. Although effective, this process generates hazardous emissions, particularly PM, which are known to be carcinogenic and pose serious environmental and health risks. To date, no studies have been conducted to map the dispersion patterns of these toxic compounds around the Tlekung site. This research aims to analyze the distribution patterns of PM pollutants emitted from incinerator, determine the potential exposure levels for landfill workers and nearby residents, and assess the associated health risks. The study was conducted for four months within a 1 km radius of the site. A descriptive quantitative method was employed, utilizing AERMOD software to model the pollutant dispersion. The data used included meteorological, topographical, and emission source information, which was processed to produce isopleth maps illustrating the pollutant distribution. The findings indicate a significant spread of PM emissions from the incinerators into the surrounding areas, with notable health risk potential, especially for residential zones near the site. The results of this study are expected to serve as a scientific basis for local government in formulating waste management policies that prioritize environmental safety.
