Abstract

Indonesia is a country located at the confluence of the Indo-Australian and Eurasian plates, which collide with each other, one of which is off the west coast of the island of Sumatra. This situation carries a significant risk of triggering a tsunami disaster. To minimize these risks, it is necessary to provide disaster awareness to all groups, especially students. This study aims to produce an e-booklet on integrated wave material for tsunami disaster mitigation on the outermost islands of Sumatra's west coast. The study employs a research and development methodology. The research instruments were questionnaires, interview guides, validation sheets, and questions. We conducted descriptive, quantitative, and qualitative data analysis. The research results led to the production of an integrated e-booklet for tsunami disaster mitigation, tailored to the region's potential in mitigation efforts. The level of disaster preparedness after using the e-booklet is included in the high preparedness category. The relationship between knowledge and level of disaster preparedness is linear. So that this e-booklet can be used as teaching material to provide disaster preparedness on the outermost islands of the west coast of Sumatra.

Abstract

Concerns have been raised over the availability of water in the Dendam Lake neighborhood of Bengkulu City and the areas surrounding it. The location is characterized by a number of unsuccessful water wells. These issues are the direct and indirect results of the geological formations that are present in the region, specifically Aluvium (which consists of boulders, clasts, sand, silt, mud, and clay). A MAE X-612 EM resistivity meter was utilized in order to get a total of twenty Vertical Electric Sounding (VES) measurement points. Using the software programs Progress and Surfer, the data that was gathered was plotted on a two-log graph. The geoelectric layer and layer parameter maps that were made were prepared with the use of quantitative and qualitative interpretations. It was determined that there were between three and five geoelectric layers. It has been demonstrated that the resistivity of the subsurface shallow groundwater zone ranges from 10 to 20 Ωm at a depth of 4 to 15 meters. According to the findings of this research project, employing the VES geo-electrical exploration approach is likely capable of effectively outlining the subsurface and shallow groundwater. In addition, there is no information available regarding the precise depth of the groundwater table in the region. On the other hand, the underground groundwater at this location has a depth that is shallower than the norm.
