Abstract

This study investigates the geological diversity of the Tanjung Api region in Tojo Una-Una Regency, Central Sulawesi, with the aim of identifying potential sites for geotourism and geological heritage designation. Through field observations, lithological and geomorphological mapping, petrographic analysis, and structural interpretation, ten geological sites were inventoried. Among them, Gua Kehidupan and Tanjung Api were identified as fulfilling national criteria for geological heritage due to their exceptional features, including fossil-bearing caves, sinkholes, and active gas seeps related to tectonic brecciation. The remaining sites exhibit significant geotourism value, particularly in coastal, volcanic, and sedimentary contexts. Findings from this study highlight the relevance of geodiversity in supporting sustainable tourism and geoconservation. By integrating geological features with educational and community-based values, Tanjung Api demonstrates strong potential to be developed into a geotourism destination that balances scientific significance, cultural relevance, and ecological preservation. The inventory and qualitative assessment serve as a reference for future geoheritage planning and site management. The study recommends involving local stakeholders in the promotion and conservation of these sites to ensure long-term sustainability and community benefits.

Abstract

Serpentinite rock is one of the mineral sources of magnesite this is known by the considerable content of the element magnesium (Mg). Testing the physical and chemical properties of serpentinite rocks found in certain locations is considered to have considerable prospects to be utilized and developed. The research was conducted in Uekuli Village Tojo Una-Una Regency Central Sulawesi Province using X-Ray Diffraction (XRD) and X-Ray Flourescence (XRF) methods. The results of XRD analysis obtained 4 types of minerals in the ST 02 test sample namely olivine as much as 3.4% lizardite 72.4% forsterite 18.6% and orthopyroxine as much as 5.6%. While at station 09 2 minerals were obtained namely lizardite 97.5% while hematite was 2.5%. Meanwhile based on the results of XRF testing the ST 02 sample has a dominant compound of MgO as much as 42.754% and SiO2 as much as 43.185%. Similarly the ST 09 sample has a dominant compound of MgO as much as 39.314% and SiO2 as much as 40.866%. In the analysis results it can be seen that the content of Al2O3 and K2O is quite low while the content of MgO and Fe2O3 is quite high. The high content of MgO and SiO2 is a characteristic of serpentinite rocks where serpentinite rocks are rich in magnesium and silica.

Abstract

The socialization program on the Tanjung Api Geotrek Route was carried out to enhance the understanding, awareness, and capacity of the Tourism Awareness Group (Pokdarwis) of Labuan Village in managing geotourism potential based on local geological heritage. The Tanjung Api area in Tojo Una-Una Regency, Central Sulawesi, is known for its natural fire phenomenon caused by the release of flammable natural gas, giving the site unique scientific, educational, and tourism value. Using a participatory approach, the program included material presentations, interactive discussions, the introduction of geotrek route design, and field observations at several potential geosites. The results show that participants’ knowledge increased by 80–90% regarding geotourism concepts, geological resource conservation, and strategies for developing interpretive educational geotreks. Participants also demonstrated strong enthusiasm to engage in destination management and benefit from the economic opportunities offered by tourism activities. This program serves as an initial step in strengthening collaboration between the community, academia, and local government to support sustainable geotourism development. The socialization provides a foundation for achieving independent, well-directed, community-based management of the Tanjung Api geosite as part of broader geotourism development in Tojo Una-Una Regency.
