Analysis of Spatial Distribution of PM2.5 and Human Behavior on Air Pollution in Jakarta

Abstract

Abstract Particulate matter is one of the threatening pollutants harmful to health. Currently, many researchers focus on the problem of PM2.5 concentrations in urban areas. This study aims to estimate the spatial distribution of PM2.5, and identify human behavior on air pollution in Jakarta. The method used were Spline with Tension to build the PM2.5 models, and multiple linear regression models to analyze human behavior on air pollution. The results showed that the annual average of PM2.5 in the last two years tends to be high in western, southern, and eastern parts of Jakarta. In addition, there was a decrease of PM2.5 concentration in 2020 compared to 2019 assumed as a result of Covid-19 Pandemic restrictions. Besides, analysis results showed a significant association between knowledge and attitude aspects on the action aspect. Based on descriptive analysis, people have good knowledge of air pollution and also concern to reduce air pollution. However, the actions for air pollution control are still not maximized which may cause high PM2.5 concentrations in Jakarta. We conclude that to reduce air pollution, the government should focus on the border areas of Jakarta and it can be done by increasing public knowledge and raising awareness for air pollution.
