【 摘 要 】

Urbanization of the last decade contributed to the urban morphological changes in Yogyakarta Urban Area (YUA). These conditions have an impact on local climate zone variations. There is an urgent need for enhanced climate-based urban planning. This study aims to: 1) Classify the Local Climate Zone (LCZ) in YUA using the World Urban Database Access and Portal Tool (WUDAPT) method, and 2) develop climate-based urban planning recommendations of the classification results. WUDAPT method used in this research based on the concept of LCZ framework by utilizing Landsat 8 imagery. LCZ classification of the whole area is determined using random forest classifier algorithm by SAGA GIS. The results of this study indicate that there are 12 LCZs in YUA, consisting of 6 types of LCZ based on building type and 6 LCZs based on land cover type. The highest increase of LST are in LCZ 3 and LCZ 5. Consequently, there's a change in diurnal temperature from low to medium. Therefore, the thermal comfort aspect define by four components of LCZ is important in YUA urban planning strategy.
