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.

Abstract

Air quality simulation has been performed for additional capacity of Banten 1 x 600 MW Coal Fired Power Plant toward air quality degradation in its surrounding environment. The simulation was based on pollutant gas dispersion calculated using Gaussian Plume equation. The research has involved climate secondary data on Cengkareng climatology Station for last 10 years. Besides, the primary data has also been taken in 7 point sampling locations to determine initial ambient air quality of existing 1 x 600 MW Coal Fired Power Plant. The data of existing 1 x 600 MW coal fired power plant has been taken from Adipala Steam Power Plant while the gas pollutant dispersion simulation has been done well using Gaussian Plume equation. The result showed that gas emission for NO2, and TSP parameter in all scenarios and SO2 gas parameter in several scenarios were exceeding the Threshold Limit Value. Thus, a technology is needed to minimize produced emission gas. The increase of gas pollutant in all sampling locations was not significantly increasing and those gas pollutants were not generally exceeding the Threshold Limit Value permitted by the government regulation.

Abstract

Analysis of Fe3+ ion present in aqueous solutions is always of interests. Recently, this ion has been analyzed by colorimetric methods using colloid of silver nanoparticles (AgNPs) in capping agents of polymers. The reaction mechanism between AgNPs and Fe3+ is still subject to the further investigation. In this work, 1,10-phenanthroline was used to probe the reaction mechanism between AgNPs and Fe3+ ion in the solution. The colloids of AgNPs were prepared in the polyvinyl alcohol (PVA) solution and reacted with Fe3+. The colloid surface plasmon absorbance decreases linearly along with the increase in Fe3+ concentration. The addition of 1,10-phenanthroline to mixture changes the solution to red, indicating that the reaction produces Fe2+. This suggests that the reduction of the AgNPs absorbance is the result of oxidation of the Ag nanoparticles along with the reduction of Fe3+.
