Abstract

This study aims to evaluate the tsunami hazard potential in the Bali region using multi-scenario numerical modeling to support disaster mitigation and early warning planning. Tsunami simulations were performed using the Tsunami Observation and Simulation Terminal (TOAST) with the EasyWave module. The model inputs were derived from the BMKG historical earthquake catalog and the 2017 Indonesian Seismic Hazard Map (PUSGEN), focusing on the Flores Back Arc Thrust segment north of Bali. Four earthquake magnitude scenarios (Mw 7.0, 7.2, 7.5, and 8.5) were simulated to estimate maximum wave heights and tsunami arrival times along the Bali coastline. The results indicate that nearly all coastal areas of Bali are vulnerable to tsunami impacts. In the worst-case scenario (Mw 8.5), maximum wave heights exceed 5 m in Sanur (Denpasar), Klungkung, and southern Karangasem, with short arrival times ranging from 5 to 22 minutes, corresponding to the highest warning level. Although moderate-magnitude scenarios (Mw 7.0–7.5) generate lower wave heights, tsunami arrival times remain rapid, indicating limited evacuation opportunities. These findings highlight the urgency of multi-scenario tsunami hazard assessment, enhancement of tsunami early warning systems, and improvement of evacuation preparedness to reduce tsunami risk in Bali.

Abstract

This study produced an audiovisual learning media based on the scientific approach for Grade V elementary school electricity material. The media was developed using a Research and Development (R&D) model with the ADDIE approach, up to the development and validation stages. Data collection instruments included teacher and student questionnaires, teacher interviews, and observations. A total of 28 Grade V elementary students participated as respondents. Validation results by material and media experts showed a very high feasibility level (83.33% and 97.33%). Analysis of teacher and student responses indicated the media's effectiveness in improving understanding and learning motivation. Further research is needed to validate the effectiveness and sustainability of this learning media in the long term.

Abstract

Gerung is one of the sub-districts in West Lombok Regency. Based on data from BNPB the Gerung sub-district area is an area that is vulnerable to the natural phenomenon of earthquakes, because the soil in this area has a softer texture so that when vibrations occur, the vibrations will be stronger. Geologically, this alluvium formation is very vulnerable to the natural phenomenon of earthquakes because it is related to the thickness of the sediment. This research aims to determine the thickness of sedimentary rocks in the Gerung District. One of the Geophysical Methods used in this research is the Geomagnetic Method. Based on the 2-Dimensional modeling of the AA' - FF' Incision, it consists of five rock layers, namely the first layer includes Silt Rock, the second layer includes Sand Rock, the third layer includes Clay, the fourth layer includes Breccia Rock and the fifth layer includes Lava Rock. The composition of the five rock layers, layers including sedimentary rock is found in the first layer to the fourth layer. The results of the research for sediment thickness from the six incisions ranged from 405 m – 485 m. Based on the results of this research, it can be concluded that Beleka Village and Dasan Tapen Village it is composed of five rock layers with a dominant sediment thickness of 485 m, namely at the AA' incision in the western part of Beleka Village
