Abstract

Erosion and sedimentation are two significant issues influenced by hydrodynamic activities and sediment transport, leading to many hydrological changes in a watershed. Erosion in a watershed streamflow will cause sedimentation and riverbed shallowing. A similar situation occurs in the Mentaya Watershed, where sedimentation has triggered a rise in river water levels, increasing the potential for flooding during rainfall events. The RUSLE method in assessing erosion rates provides results that can inform effective erosion control strategies under the current conditions of the Mentaya Watershed. This study aimed to identify the current conditions of the Mentaya Watershed and monitor the estimated magnitude of erosion and sedimentation through RUSLE calculations using Google Earth Engine (GEE). The study results showed a dynamic increase in erosion rates in the Mentaya Watershed from 2016 to 2024, with the highest predicted figure reaching 509.84 tons/ha/year in 2024. The highest amount of transported sediment was found in 2024, occurring in areas with slopes greater than 40%, while the lowest transported sediment was found in areas with moderate slopes of 10-20%. The sedimentation level in the Mentaya Watershed was expected to continue increasing in line with the high erosion rates. This condition will significantly affect the levels of erosion and sedimentation vulnerability in the Mentaya Watershed.

Abstract

The Geotpack (Geography Technology, Pedagogical, and Content Knowledge) Improvement Training for geography teachers in Situbondo Regency based on 3D Map Excel aims to overcome obstacles in the use of technology in geography learning. This training consists of three main stages: preparation, implementation, and evaluation and reflection. In the preparation stage, researchers identified the problem of low optimisation of technology use that hampers teachers' ability to teach spatial thinking concepts. The training then focused on the use of 3D Map Excel to visualize geographic data in three-dimensional form. During the training, participants were introduced to the TPACK concept that integrates technology, pedagogy and knowledge content. The practice of creating 3D maps was conducted using data from the Central Bureau of Statistics (BPS), with intensive mentoring to ensure the success of each participant. The evaluation results showed that all participants successfully applied the 3D map-making technique and planned to apply it in the classroom learning process. The implementation of 3D Map Excel technology is expected to increase the effectiveness of geography learning, create a more interactive and interesting atmosphere, and increase students' interest in learning. This training confirms the importance of improving teachers' competence in utilizing technology to create an innovative and effective learning environment.
