Abstract
The research was conducted in the UNESCO World Heritage Area Merangin Jambi. This area located in the tropical rainforest of Sumatera which included in the physiography of the Barisan Mountain Range with an area of 4,832.31 Km2around 62% of the total area of Merangin Regency. he threat ofdisasters that could come at any time will affect the impact of the large geotourism potential in the MJUGGp Territory, thus requiring effective disaster mitigation as an effort to conserve geological heritage. This research focuses on landscape character based. Disaster mitigation using geomorphological analysis and remote sensing. Geomorphological approach by considering aspects of morphology, morphogenesis and morphoconservation using remote sensing studies. This area is divided into
significant zone and supporting zone. The core zone is in the central part of the area with geological sites of international value from the presence of Permian-aged flora and fauna fossils, then the supporting zone in the northern part with complex Jurassic Cretaceous karst, and the other supporting zone in the western part is a volcanic complex consisting of from the Masurai Caldera, Mount Sumbing, and Mount Hulunilo are Quaternary age. The western supporting zone in the Barisan Ranges Zone is associated with the active fault of the Small Segment Sumatran Fault System and is a zone that is vulnerable to disasters, such as earthquakes, landslides and floods. The ecological area in the western zone of the MJUGGp Territory is a zone that needs disaster mitigation. The results of the research show that 60% of the landscape ecological zone is in disaster areas with a level of earthquake and landslide risk reaching 80% of the total landscape ecological zone. Meanwhile, the flood-prone level of the landscape ecological zone reaches 60%. Based on the results of disaster identification in the MJUGGp Territory, there are mountains with igneous rock complexes such as granitoid, andesite and pyroclastic rocks.
