Abstract

Air temperature in urban areas tends to be higher compared to suburban areas. To address this issue, local governments utilize blue open spaces, which can increase humidity and lower air temperature. In addition, the availability of green open space along lakeshores also offers potential for reducing air temperature. This study aims to measure the microclimate regulation services of three lakeshores in Jakarta (Setu Babakan, Srengseng Urban Lake Forest, and South Sunter Lake) using Landsat 8 imagery. The results show that Srengseng Urban Lake Forest has the lowest mean land surface temperature (LST) at 18.81 C, followed by South Sunter (19.67 C) and Setu Babakan (20.07 C). These findings indicate that LST can be influenced by various factors beyond land cover, such as slope and terrain gradient. These factors can serve as important considerations for stakeholders in designing thermally comfortable public open spaces for visitors.
