Abstract
Air pollution generated from airport activities has become public concern and the subject of more rigorous government regulations. The Airport Operators are stipulated to control the pollution and for the accountability of air quality that might affect public health. The main objective of this study is to establish a model for the distribution of air pollutants and to predict their concentrations generated by the runway and apron operations at Sam Ratulangi International Airport (Manado) until 2024, in accordance with the airport expansion program. The data was collected in the airport surrounding area in 2018, while the climate data over a span of 10 years, from 2009 to 2018, was obtained from Sam Ratulangi Meteorological Station. The modeling on dispersion of air pollutant gases was developed by the Gaussian Plume Equation. The simulation was performed using AERMOD software, and the results visualized by GIS software. AERMOD software was recommended by the US-EPA to predict the impact of air pollutants. The results predicted that the maximum concentrations of NOx; HC; and CO generated by runway activities modeling in 2024 were 250 μg.m-3; 6.4 μg.m-3; and 87 μg.m-3 respectively. The results also predicted that the maximum concentrations of NOx; CO; and PM10 due to apron operational activities in 2024 were 260 μg.m-3; 892 μg.m-3; and 2.5 μg.m-3 respectively. The model predicted that in 2024 the air pollution at Sam Ratulangi International Airport will remain under the limit as defined in Indonesian Government Regulation No. 22 of 2021. To mitigate the future increase in air emissions due to the increase in airport capacity, the recommendation were proposed in the several areas, which were including operation management, technology, policies and airport regulations, as well as the provision of green area.
Highlights
Transportation is an economic supporting sector which has grown very rapidly in recent years.One of the transportation sectors that has been experiencing rapid development is the aviationindustry, which is designated by capacity development and increase in the number of airports
The purpose of this study was to develop the model for the dispersion of pollutants generated by aviation activities at Sam Ratulangi International Airport using Agency Regulatory Model (AERMOD) software
This simulation was using Gaussian air dispersion modeling, and the instrumentsemployedwere including: laptop, AERMOD software released by the US EPA, GIS to visualize the results of AERMOD, and WRPLOT View from Lakes Environmental to describe wind flowers
Summary
Transportation is an economic supporting sector which has grown very rapidly in recent years.One of the transportation sectors that has been experiencing rapid development is the aviationindustry, which is designated by capacity development and increase in the number of airports. The increasing in capacity as well as the number of airports will increase the consumption of aircraft fuel and supporting transportation in airport operations. These will obviously intensify air pollutants quantities. Thereforeair pollution due to airport activities is under public and government scrutinizing. The airport operators are stipulated to control the pollution.The accountability of air quality that might affect public health and wellbeing is expected
