The current rapid expansion of cities has the potential to affect changes in climatic conditions. Human activities have an impact on these changes, either directly or indirectly. There are several essential characteristics to consider when creating a quality and comfortable environment, including thermal comfort in outdoor spaces and temperature management. Using a quantitative – quasi-experimental technique, including the Rayman simulation test model, statistical and descriptive quantitative tests, this study intends to determine the direction of physical growth in the river area, particularly open space facilities in Samarinda City. Data was gathered through two methods: field measurements and interviews via questionnaires. Using a regression equation, the researchers analyzed the relationship between climate variables, physical variables, and personal variables on the quality of outdoor thermal comfort. Then, based on the distance from the Mahakam River, determining the thermal conditions, as well as the public's perceptions of outdoor thermal sensation (TSV), outdoor wind flow sensation (WFSV), and outdoor humidity sensation (HSV). Then determine the acceptable thermal comfort range. Furthermore, identifying the factors that influence thermal comfort from a physical, climatic, and personal aspect. With a PET value range of 24 – 24.6, the majority of respondents felt comfortable with thermal conditions (temperature, humidity, and wind). The Compact Lowrise is the location with the highest PET value. Radiation temperature (Tmrt), pavement land cover, surface temperature (Ts), and aspect ratio are the most influential variables with PET values. The thermal improvement strategy required for physical development should have properties that can shade the area from solar radiation in the form of shade/trees while not interfering with the rotation of wind flow in the area, designed to allow the evaporation cooling process to run more efficiently.
