Abstract

XRF method to determine elemental content and FTIR test to determine the nature of chemical compounds (functional groups) of Litosol soil at the slope (elevation angle) and the distance of the research trajectory lines. The identified elemental levels are Fe, Si, Ti, K, Mn and Ca. Fe represents the highest elemental content value for each research path. Fe for paths (1-2) are 23.82 % and 37.69%, tracks (5-6) are 23.11% and 37.47%, and paths (9-10) are 40.44% and 33.99% at different elevation angles. The lowest element level is Ca. The value of Ca for each track is 0.24% and 0.66% (1-2), 0.28% and 0.30% (5-6) and 0.27% and 0.62% (9-10) for each different elevation angle. The FTIR method to determine functional groups (chemical compounds) uses the same parameters as the XRF method. The O-H functional groups were detected at wave numbers 3698.31 cm-1 and 3620.34 cm-1 with the theoretical accuracy ranges of 3700-3000 cm-1 and 3590-3650 cm-1. The C=C which is a double bond functional group was detected at wave number 1640.8 cm-1 in the theoretical range of 1610-1680 cm-1. The C-H functional group on each track was detected in three different types of wave numbers with values of 908.99 cm-1, 786.86 cm-1 and 746 cm-1, respectively. The range of wave number accuracy for C-H is 690-900 cm-1.

Abstract

Tabbinjai Village is susceptible to landslides due to high rainfall, steep topography, and human activities. This study aims to determine the zone of landslide vulnerability using geophysical data and satellite imagery to generate a level of landslide vulnerability map in Tabbinjai Village. The AHP (Analytical Hierarchy Process) method is used to determine the weight composition of satellite imagery data, and Seismic vulnerability and slip plane identification are geophysical methods that include the HVSR (horizontal-to-vertical spectral ratio) method and the Wenner-Schlumberger configuration, respectively. Based on the AHP method, landslide susceptibility is classified into low (60.67%), moderate (37.89%), and high (1.44%) susceptibility zones. These spatial findings are supported by the in situ seismic vulnerability index (Kg) and geoelectrical resistivity profiles, confirming the strong likelihood of slope failure in critical areas. Therefore, integrated satellite imagery and geophysical data provide a reliable reference for regional spatial planning and disaster mitigation strategies.
