Abstract

This study investigates the impact of the Martapura River on the microclimate of Banjarmasin City, Indonesia. Data were collected using twenty strategically placed sampling points along two routes adjacent to the river, with air temperature and relative humidity readings recorded at 10-minute intervals. Additionally, a portable weather station monitored these parameters over the river from 6:00 to 18:00. Using ENVI-met software, the study analyzed the effects on air temperature, relative humidity, and Predicted Mean Vote (PMV). The results indicated that the Martapura River significantly influences the local microclimate by reducing air temperatures by up to 1.5°C and increasing humidity levels by up to 5% near its banks. The cooling effect was more pronounced downwind of the river compared to upwind areas, and roads contributed to air temperatures that were up to 0.5°C higher. The study highlights the river’s role in enhancing thermal comfort and mitigating urban heat islands, emphasizing the importance of integrating natural water bodies into urban planning for sustainable development and climate resilience.
