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.

Abstract

Abstract: Dayurejo Village, on the slopes of Mount Arjuno, is an agrarian landscape where diverse land uses—teak stands, agroforestry, banana and coffee plantations, and production forest—compete for space and shape soil conditions. This study assesses soil quality under different litter conditions and interprets the findings in relation to land functions and village-level spatial planning. Using a quantitative descriptive approach, soil samples were collected from topsoil (0–30 cm) and subsoil (30–60 cm) in five land-use types and analyzed for texture, porosity, pH, and organic matter. Rudi Hartono nic C, while litter thickness, pH, and moisture were also measured. Results indicate that all land uses are characterized by acidic soils with very low organic C (<0.60%) and litter layers that are generally dry, limiting decomposition. Agroforestry and forest land maintain relatively high porosity and thick litter, supporting their role as hydrological protection and buffer zones, whereas banana, coffee, and teak areas exhibit compaction and degradation, requiring targeted rehabilitation. The study concludes that integrating soil-quality indicators into village zoning and agrarian management is essential for sustainable land and spatial planning in Dayurejo Village.

Abstract

Pencemaran sampah laut (marine debris) di wilayah pesisir Indonesia telah menjadi krisis sistemik yang mengancam stabilitas ekosistem bahari. Meskipun Pantai Pasir Panjang di Kabupaten Pasuruan memiliki potensi ekowisata yang prospektif, kawasan ini menghadapi tekanan polusi plastik yang signifikan. Masalah utama dalam kajian ini adalah adanya disparitas antara tingginya potensi wisata dengan kerentanan ekosistem akibat akumulasi sampah. Kesenjangan penelitian (gap) menunjukkan bahwa studi terdahulu masih bersifat parsial dan belum mengintegrasikan variabel tekanan lingkungan secara komprehensif ke dalam strategi perencanaan kawasan. Oleh karena itu, penelitian ini bertujuan menganalisis pengaruh marine debris terhadap tipologi pantai dan merumuskan strategi pengembangan ekowisata berkelanjutan. Metode yang digunakan adalah deskriptif kuantitatif melalui observasi langsung dan analisis laboratorium sedimen dengan teknik line transect. Pendekatan ini dipilih untuk memberikan data empiris yang presisi mengenai korelasi parameter fisik lingkungan dengan sebaran sampah. Hasil penelitian menunjukkan bahwa sampah plastik jenis meso-debris (5 mm–2,5 cm) mendominasi kawasan dan telah terintegrasi ke dalam sedimen pasir kerikil, yang mencerminkan rendahnya manajemen limbah domestik. Limitasi penelitian ini terbatas pada observasi spasial di tiga segmen pantai saat musim tertentu. Rekomendasi yang diusulkan adalah pengembangan ekowisata partisipatif melalui program coastal clean-up tourism, zonasi berbasis komunitas, dan penguatan literasi lingkungan digital untuk menjaga keberlanjutan ekosistem pesisir.
