Abstract

Air pollution is the entry of harmful elements into the atmosphere, resulting in a deterioration of environmental quality. Dense settlements are one of the factors contributing to the decline in environmental quality. This study aims to formulate a plan for managing and monitoring air quality to minimize the impact of declining environmental quality in a settlement development project. The research method involves analyzing air quality based on ambient air quality test results, evaluating potential impacts based on parameters from ambient air quality tests, comparing the ambient air quality test results with relevant quality standards, and formulating a plan for air quality management and monitoring. Data collection techniques encompass qualitative and quantitative methods. Based on the analysis of ambient air quality test results at the location of the proposed settlement development project, the test values are higher compared to the surrounding areas of the project site, but they do not exceed the quality standards stipulated in Government Regulation Number 22 of 2021 concerning the Implementation and Management of the Environment, Annex VII Ambient Air Quality Standards. Therefore, the formulation of an air quality management and monitoring plan is essential, especially when the construction and operational phases of the settlement development project are underway. This effort aims to minimize air pollution that could degrade environmental quality and to support sustainable settlement development while considering environmental aspects.

Abstract

Nickel mining activities have negative impacts on the environment, one of which is a decrease in air quality due to increased concentrations of air pollutants. Types of pollutants emitted from mining activities, including particulates, SO2, PM and NOx. Therefore, an air dispersion simulation is carried out to determine the maximum level of emissions released from the nickel mining process. This study uses a numerical modeling approach with Aermod View software to simulate the process of dispersion of SO2, PM and NOX air emissions in the distribution of emissions from nickel mining activities. Based on the simulation image of SO2 NOx gas dispersion, and particulates are scattered westward from the emission source/chimney following the wind direction. The dominant dispersion of SO2, NOx and particulates towards the west corresponds to the dominant wind direction. The highest SO2 concentration is around 22.57 x 10^-9 g/Nm3 which is located at a distance of approximately 100 meters from the emission source. The highest NOx concentration is 15.63 x 10^-9 g/Nm3 which is located at a distance of approximately 100 meters.
