ABSTRACT Cangar Hot Springs (CHS) located at flank of Arjuno-Welirang Volcano Hosted Geothermal Field in Batu city, East Java has a high potential as pilot project of regional in the frame of Ecotourism and Edu Techno Park development. A few hot spring found in the Arjuno-Welirang volcanic complex, such as Padusan hot spring, Songgoriti hot spring, Kasinan hot spring, and Cangar hot spring. Based on previous Peak Ground Acceleration observations, the area was concluded a safe zone indicated by low seismic index. Furthermore, based on the self potential investigations, the fluid flow around CHS can be predicted that the direction of hot fluid flow spread from southeast to northwest. This results can be used to consider a high potential for Eco tourism of CHS mainly related to the use of hot springs and community education related to volcano hosted geothermal. We develop a concept and observed some aspect to improve the development CHS area as Ecotourism and Edu Techno Park. In addition, the visual observation shows that the occurrence of solfatara and fumaroles with magmatic gasses indicated the existence of a volcanic geothermal system in the subsurface around Arjuno-Welirang volcano hosted geothermal complex. This visual observation can be done direct from the developed Cangar Techno Park area on UniversitasBrawijaya for monitoring of ArjunoWelirang volcanic eruption as part of integrated ecotourism concept and idea to community education for developing of geothermal prospecting area.
