Geothermal as one of the potential environmental services in conservation areas is increasingly being taken into account. According to the Government Regulation No. 25 of 2021 on the Implementation of the Energy and Mineral Resources Sector, geothermal can be used directly or indirectly. The geothermal tourism of Awit Sinar Alam Darajat is an example of the direct utilization of geothermal energy for tourism. This study aims to assess the impact of geothermal tourism on the environment and develop environmental management and monitoring. The analysis was carried out utilizing a qualitative and quantitative methods approach. Data were collected from secondary data and analyzed to develop environmental management and monitoring. The result showed that the environmental impact of geothermal tourism includes the change of land use, the decrease in geothermal quantity and the generation of quality, and solid waste. We recommend environmental management, such as setting the minimum standard for the Green Base Coefficient of 70%, geothermal conservation, providing the geothermal treatment plant, and solid waste management. Environmental monitoring should be applied when calculating the Green Base Coefficient and the quantity and quality of geothermal and solid waste generation to achieve the standard.
