“…The smallest part of the watershed is the smallest unit, where all hydrological processes were simulating [8]. The concept of HRU is according to an integrated systems approach which is a requirement to analyze and dynamically model the hydrology of the heterogeneous drainage structure of the watershed and its interaction with soil, geology, and land cover [9]. HRU is the smallest land unit obtained by overlaying soil, land use, and slope data [10].…”

Rahakolowu Watershed is an important and strategic issue area for the South Buton Regency. The characteristic of this region is in the form of hills and having wavy until the very steep slope which is very potential of having high run-off. The purpose of this study was: 1) to determine the potential for surface run-off that occurs in the Rahakolowu Watershed; 2) to map the potential for flash floods that occur in the Rahakolowu Watershed. The approach used in this study was a modified HRU (Hydrological Response Unit) with a run-off occurrence land unit as its unit analysis. Based on the result, the highest run-off water discharge produced in each sub-basin was an average of more than 0.50 m3/sec, both on forest, moor, residentials, mix garden and shrubs. The high slope and the area of each land unit in a flow occurrence is the factor causing the high run-off in the Rahakolowu Watershed. Flash floods occur along the main river channel and become inundation floods when they reach downstream. The accumulation of run-off in the southern sub-basin has more potential as a flood contributor in the Rahakolowu Watershed.

“…The proper mitigation of UHI is add the vegetation cover, especially natural vegetation and also artificial vegetation [17,18]. According to Depok City is a city that has a lot of vegetation due to the University of Indonesia (UI) campus, also located in Depok which there is an urban forest in UI Campus [19]. Urban forests can improve the microclimate quality to reduce LST and UHI [20,21].…”

Urban Heat Island (UHI) explains the occurrence of excessive heat that spread unevenly in urban areas. Intense and complex human activities in urban areas are mainly causing the formation of UHI. This study aims to identify the spatial characteristics of UHI in a complex urban feature, like the Universitas Indonesia campus area and its surroundings in Depok City. The campus and its surroundings might represent a complex urban area and can be used as a reference to understand the widespread impact of UHI. UHI was determined based on the threshold value, calculated from the average and standard deviation of the surface temperature. This study utilized Landsat 8 OLI-TIRS imagery to extract Land Surface Temperature (LST) value. The LST observations were collected for three different periods, including 2013, 2017, and 2021. The LST value tends to be increased during these times, with the LSTmax recorded at 34.68 °C, 35.47 °C, and 36.4 °C for 2013, 2017, and 2021, respectively. Based on the number of the accommodated grid, the UHI was getting larger every year. Started from 313 grids in 2013, the UHI has been expanded to more than 550 grids in 2021.
