Abstract

Green open spaces play an important role in improving urban environmental quality through microclimate amelioration and thermal comfort creation. This study evaluates the role of vegetation in microclimate improvement (through its shade and wind reduction) and analyzes thermal comfort levels based on measurements and visitor perceptions in the Pagutan Green Open Space, Mataram City. Data collected included vegetation characteristics, air temperature, humidity, and visitor perceptions. The analysis used the Key Performance Index (KPI) to assess shade and wind reduction, and the Temperature Humidity Index (THI) to evaluate thermal comfort. Results showed the average KPI was good, with shade effectiveness of 79% and wind reduction of 80%. THI values ranged from 26–29°C, with dense vegetation showing the lowest THI (27°C). Based on visitor perceptions, 76.7% felt comfortable, highlighting vegetation’s role in enhancing microclimate comfort.
