This study investigates the impact of land use variations on air quality and public health in Bandung Regency, Indonesia, from 2019 to 2021. Utilizing advanced spatial and temporal analysis techniques, the study meticulously examines extensive datasets of geospatial coordinates and air quality parameters (NO2 & SO2) obtained from both ambient measurements and passive sampling. Geographic Information Systems (GIS) technology plays a pivotal role in visualizing air pollutant patterns across diverse land use types, including industrial, residential, agricultural areas, urban centres, and transportation corridors. The findings reveal significant spatial and temporal variations in air quality, particularly near agricultural zones, industrial hubs, urban centres, and transportation corridors. The region is predominantly characterized by rice fields, covering 76.91% of its total land area, alongside significant forested regions and urban settlements. The study identifies a notable seasonal decline in NO2 and SO2 levels through the years, with higher concentrations typically observed during the dry season compared to the wet season. Correlation analysis between LULC and respiratory diseases showed strong negative correlations for industrial areas with ISPA and nasopharyngitis, which contrasts with some existing research linking industrial pollution to higher respiratory disease rates. Correlation analysis between LULC and air pollutants indicated varied relationships; for instance, industrial areas showed a moderate positive correlation with NO2 and a moderate negative correlation with SO2, highlighting the complex interactions between different land uses and pollutant levels. Additionally, ambient data generally showed negative correlations between NO2 and respiratory diseases, whereas passive sampler data indicated positive correlations. Correlation results between pollutant concentrations and respiratory diseases in Solokan Jeruk PHC showed statistically significant moderate negative correlations between NO2 and the common cold, indicating that higher NO2 levels might be associated with fewer cases of the common cold. The comprehensive approach of the study and significant findings contribute valuable insights into the intricate relationship between land use, air quality, and public health, offering a crucial foundation for policy-making and environmental management in Bandung Regency.
