Correlation analysis between Carbon Monoxide and industry in Bekasi from 2019-2022

Abstract Carbon monoxide is a colorless, odorless, and poisonous gas. For several decades, industry contribute as the main factor of the increases of carbon monoxide in the atmosphere. Bekasi has the largest number of industries in West Java and has continuously an increasing trend. This will contribute to the increases of carbon monoxide concentration in the city. This study analyzes the spatial increases in carbon monoxide concentration due to industrial growth in Bekasi city and its vicinity from 2019 to 2022. The carbon monoxide time series data were obtained from Sentinel-5P satellite imagery, downloaded and processed using Google Earth Engine. The analysis reveals that the carbon monoxide concentration in Bekasi ranges from approximately 0.037 mol/m 2 to 0.041 mol/m 2 . District-level analyses indicate that Tarumajaya consistently exhibited high CO levels, reaching 0.044 mol/m 2 in 2020. Furthermore, the results show a moderate correlation of 0.688 between industrial growth and carbon monoxide concentration, indicating that as the number of industries increases, CO levels in Bekasi rise accordingly. Additionally, this study examines the influence of wind direction on the spatial distribution of carbon monoxide, highlighting that winds from specific directions can transport CO to areas farther from its source, resulting in variable concentration levels across the region.
