Abstract

Jember is a disaster-prone area, especially earthquakes. Disasters can cause many losses, ranging from casualties to property so that knowledge about disaster mitigation is very important to minimize the consequences caused. The purpose of this study is to determine the level of knowledge of Jember University students related to earthquake disaster mitigation. The research method used in this study is descriptive quantitative. This research was conducted on students of the University of Jember using test questions consisting of 10 questions. Data analysis was conducted by giving a score range of 1-4 on each question item, then the total score was converted into a score range of 0-100. The results of the analysis showed that the average overall score was 69.4, which is equivalent to a percentage of 69.4%. Therefore, the level of knowledge of Jember University students related to disaster mitigation is in the moderate category.

Abstract

This study aims to determine the subsurface structure in landslide-prone areas and to identify the potential for landslides in Subo Village, Pakusari Subdistrict, Jember. The survey was carried out using the resistivity geoelectrical method with Wenner-Schlumberger configuration and 2 m electrode spacing. Four trajectories of different lengths were used, namely 50 m for Trajectory 1, 30 m for Trajectories 2 and 3, and 26 m for Trajectory 4. The data obtained are the magnitude of the potential difference (V) and the magnitude of the current (I), then processed using Res2dinv software to obtain a 2D section and Voxler to obtain a 3D section. It was found that the subsurface structure consists of clay layer with resistivity of 1,48-37,9 ?m, the next layer is sand layer with resistivity of 8,53-192 ?m and sandstone layer which is quite dominant in Tracks 1 and 4 with resistivity value > 432 ?m. The results of landslide potential identification with 3 indicators were also obtained. It can be concluded that Subo Village, Pakusari Subdistrict, Jember is composed of clay, sand and sandstone layers and has a high landslide potential.
