GEOSITE ASSESMENT OF THE TRACE OF MESOZOIC SUBDUCTION IN LUBAR VILLAGE, MUARA DUA DISTRIC, SOUTH SUMATERA PROVINCE, INDONESIA

Lubar Village, in Muara Dua District, South Sumatera Province, Indonesia, has high geotourism potential due to its geological characteristics related with Mesozoic subduction events. This project will evaluate the geotourism value of two significant sites—Situlanglang Hill and the Insu River Waterfall—using scientific, educational, economic, and environmental criteria. Field studies, petrographic and paleontological examinations, and site appraisals were carried out to assess each site's potential and difficulties. The results suggest that the scientific value is considerable (75-88%), notably at Situlanglang Hill, whereas the educational and economic values are low (50% and 33%, respectively) due to poor infrastructure, access, and public awareness. Conservation ratings range from 50% to 63%, indicating a lack of institutional protection despite existing environmental challenges. However, both places have additional value due to their cultural, ecological, and aesthetic significance. This study emphasizes the importance of integrated management, educational outreach, and community engagement in promoting sustainable geotourism development in Lubar Village.
