Indonesia is a country that has 40% of the world's geothermal potential, but only 3% was used.Research to determine the potential for geothermal distribution in the southern part of MountTampusu is by taking data directly using a thermometer, the purpose of this research was todetermine the temperature distribution at a depth of 0 cm, 30 cm, 60 cm, 90 cm by mapping. Thedata obtained is primary data, then entered into Microsoft Excel. In Microsoft Excel analyzed of themaximum, minimum and average temperatures. Then from the temperature data in the form oftemperature contours based on depth by using surfers 11. From the results of data processing usingsurfers, it was found that the temperature distribution in the southern part of Mount Tampusu variedin value, in the morning at depth 0 cm, 30 cm, 60 cm, 90 cm has value 23.5775°C, 22.67°C,23.315°C, 24.1025°C, daytime at depth 0 cm, 30 cm, 60 cm, 90 cm has value 27.5675°C,24.2525°C, 24.1825°C, 24.6925°C, in the evening at depth 0 cm, 30 cm, 60 cm, 90 cm has value24.5525°C, 24.3525°C, 24.2825°C, 24.605°C. The temperature pattern in the southern part ofMount Tampusu has a perpendicular pattern and slightly spreads to the northwest.

Objective: To investigate the shallow subsurface temperature profile of warm ground geothermal manifestations in the Bukit Kasih area, Minahasa, North Sulawesi, Indonesia. Specifically, this study examined the relationship between temperature variation and subsurface depth to develop a preliminary thermal model of geothermal manifestations. The study contributes to geothermal resource assessment and supports sustainable renewable energy development in line with Sustainable Development Goal 7 (Affordable and Clean Energy). Method: The study employed a field-based quantitative approach through direct temperature measurements at warm ground geothermal manifestation sites. Temperature data were collected from several randomly selected measurement points at shallow subsurface depths ranging from 0 to 200 cm. The research was conducted over six months, consisting of field surveys, preparation of measurement equipment, geothermal manifestation observations, temperature data acquisition, laboratory analysis, and data processing. The temperature gradient and depth-temperature relationship were analyzed to determine the subsurface thermal characteristics and develop temperature distribution models. Results: The results showed that the shallow subsurface temperature gradient of warm ground manifestations in the Bukit Kasih geothermal area varied from 13.61 to 71 °C/m. The temperature-depth relationship demonstrated a linear pattern at shallow subsurface depths, indicating a consistent increase in temperature with increasing depth. Meanwhile, the temperature model at greater depths followed a logarithmic function pattern, reflecting changes in heat transfer behavior within the subsurface environment. These findings provide important information regarding shallow geothermal characteristics and potential indicators for further geothermal exploration. Novelty: The study provides new insights into the shallow subsurface thermal characteristics of warm ground geothermal manifestations in Bukit Kasih, Minahasa, North Sulawesi, by developing a temperature-depth model based on direct field measurements. The findings contribute to geothermal exploration strategies and the advancement of renewable energy utilization in accordance with SDG 7 (Affordable and Clean Energy).
