Land cover changes in watersheds can affect various hydrological aspects, such as river flow, sedimentation, and water quality. Land cover changes from forests to farmlands or settlements can cause significant changes in local hydrological cycles. This study aims to analyze the dynamics of land cover change and its impact on the hydrological conditions in the Tiworo watershed. The study was conducted in the Tiworo watershed, covering Muna and West Muna Regencies, with an area of 25,445.84 Ha. Using the soil and water assessment tool (SWAT), the results of the study for the period from 2017 to 2022 showed no groundwater flow. This condition reflects a potential issue with the groundwater parameters in the model or a lack of groundwater recharge during this period. However, as rainfall increases, groundwater loss is influenced by land conversion to settlements and the mixing of dryland agriculture with shrubs, ponds, and rice fields. The magnitude of surface runoff, the decrease in lateral flow (interflow), water yield, and the reduction in infiltration processes increased the fluctuations in Qmax (m3/s), Qmin (m3/s), and the flow regime coefficient (KRA) in the Tiworo watershed.

One of the alternatives to control the impact of environmental problems is the existence of open space. In particular, the green open space included in the study is the urban forest. This research aimed to provide new scientific insights in identifying urban forest locations based on the criteria of Government Regulation Number 63 of 2002, as well as analyzing microclimate data through field observation activities and quantitative analysis. Urban forests based on these criteria are the South Sulawesi Governor’s Office, Hasanuddin University, Pakui Sayang Park, Hasanuddin Park, Macan Park, and MoI (Maccini Sombala of Indonesia) Park. The highest level of vegetation density is in the Hasanuddin University area, and the South Sulawesi Governor’s Office, which is 0.38. Meanwhile, the lowest is in Pakui Sayang Park, Hasanuddin Park, and MoI Park, which is 0.34. The air temperature in the Governor’s Office and MoI Park is in the hot category, which is 30.9 °C, whereas the air temperature in other urban forests is in the very hot category, which is 31.1 °C to 31.8 °C. The air humidity in Pakui Sayang Park is 67.5 with a dry category, while the other urban forests are in the slightly dry category of 71.3% to 74.4%. Thermal comfort at all study sites is in the moderately comfortable category, wind speed is in the calm to shady category. The findings of this study highlight the importance of urban forests as one of the indicators that play an important role in overcoming the problem of increasing temperatures that have an impact on the comfort of people in urban areas.
