Geotourism sites often receive little attention from the general public as interesting object to visit. Tourists generally come just to enjoy the scenery. In addition, there are many geotourism sites that are less interesting to visit, even though they have high scientific value and a wealth of knowledge stored as natural laboratories. This research aims to package exploration data of interesting stones in transport igneous rocks and beach sand for exposure to enhance tourist attraction. In this research, magnetic and geochemical methods applies to igneous transport rocks and beach sand were subjected to geochemical and magnetic susceptibility tests to provide information to tourists about the geotourism object. The geochemical test was conducted using X-Ray Fluorescence (XRF), and resulting the presence of chemical elements Si, K, Ca, Ti, V, Cr, Mn, Fe, Cu, Eu, Re, Mo, and Zn. The dominant elements with a content of more than 5% (wt) are Si, Fe, and Ca, with average values of 56.78 wt%, 24.20 wt%, and 8.41 wt%, respectively. The high Si content confirms that the contribution of igneous rocks is more dominant in the beach sand compared to coral rocks. This implies that the plate subduction in that area is relatively deep. The magnetic susceptibility test shows a magnetic susceptibility value ranging from 13 to 4143 ×10-8 m3/kg, with average 1182 ×10-8 m3/kg indicate that igneous rocks and beach sand are rich in magnetic minerals that can be utilized as industrial raw materials. The exploration data was packaged as promotional materials and presented to tourists. In addition, perfectus and location videos are presented for public access. Finally, the research network was communicated to the general public and productive communities of tourism business owners and received positive feedback regarding the benefits of this research and activities. © 2026 by the authors.
