Abstract

Ranau Lake is one of Indonesia's 30 national priority lakes facing pressures from climate change and human activities, negatively impacting its water quality and ecosystem. This study aims to analyze land cover changes in the catchment area, measure the changes in the lake's surface area, and examine the relationship between land cover changes and Ranau Lake's surface area from 2016–2022. The data includes Sentinel-1A IW GRDH imagery, ESRI land cover maps, and Google Earth images. The analysis employed Support Vector Machine (SVM) classification, spatial analysis, and linear regression. The results reveal that water bodies, vegetation, and built-up land categories experienced an increase of 36.78 hectares, 33.96 hectares, and 9.1 hectares, respectively, while bare land decreased by 80.03 hectares. Ranau Lake's surface area increased by 28.3 hectares, showing a significant relationship between land cover changes in water bodies (R² = 99.88%), bare land (R² = 94.92%), vegetation (R² = 66.06%), and built-up land (R² = 56.85%) and the lake's surface area. These findings highlight the critical role of land cover changes in influencing the dynamics of lake surface area, an essential indicator of ecosystem health. This study emphasizes the importance of sustainable land cover management in supporting Ranau Lake's conservation. Continuous use of SAR-based remote sensing technology is recommended for land cover monitoring, enabling data-driven decision-making in water resource management.

Abstract

Way Kerap, Semaka, Kabupaten Tanggamus yang berlokasi pada 104° 27' 11.68'' BT -6° 30' 7.6'' LS merupakan daerah yang sering mengalami tanah longsor karena berada di daerah yang termasuk ke dalam kawasan patahan Semangko. Patahan Semangko atau biasa disebut Semangko Fault merupakan strike-slip fault yang mengalami pergerakan horisontal, pergerakan ini dapat menyebabkan gempa bumi dan juga longsor dan mempengaruhi topografi di sepanjang jalur patahan tersebut. Untuk itu dilakukan pemetaan foto udara dengan UAV pada daerah penelitian guna mendapatkan kenampakan permukaan bumi dengan resolusi tinggi menggunakan DJI Phantom 4 Pro. Penelitian ini bertujuan untuk mengetahui pengaruh aktif dari patahan Semangko dan pemetaan kerawanan longsor di daerah penelitian. Data yang digunakan yaitu kemiringan lereng, tutupan lahan, jenis batuan/geologi, jenis tanah dan curah hujan dengan pengolahan menggunakan Agisoft Metashape Professional, PCI Geomatica 2014 dan ArcGIS 10.8. Kerawanan longsor dengan klasifikasi tinggi cenderung berada di dekat patahan Semangko. Pergerakan tanah akibat aktivitas tektonik bisa membuat lereng menjadi lebih curam atau menciptakan celah pada lereng, meningkatkan kerawanannya terhadap longsor, hal tersebut berbanding lurus pada hasil analisis kemiringan lereng yang menunjukkan daerah rawan longsor tinggi ditunjukkan pada kemiringan lereng yang curam hingga terjal yang menjelaskan adanya pengaruh aktif dari patahan Semangko. Daerah penelitian Way Kerap, Semaka, Kabupaten Tanggamus didapati pemetaan kerawanan longsor dengan klasifikasi rendah (9,32 ha), sedang (26,25 ha) dan tinggi (1,91 ha) dengan total luasan daerah penelitian sebesar 37,5 ha.

Abstract

Vulnerability is a condition of a community or society that causes the inability to face the threat of disaster. Geographic information systems (GIS) have become essential tools in evaluating natural hazards and risks which is an aspect to define vulnerability of the volcano eruption-affected area. Based on activity of volcano, it is necessary to delineate the vulnerability of areas affected by the eruption of Mount Agung by integrating the Mount Agung Area Network Map and Geological Map with physical vulnerability data and social vulnerability. This research using processing methods and spatial analysis of Geographic Information Systems (GIS) and remote sensing methods. Geographic Information System (GIS) is used to create vulnerability maps using scoring, weighting, and overlay methods. The data used for making the vulnerability map include administrative boundaries, DEM (Digital Elevation Model), secondary data from the BPS 2020 Karangasem Regencyt in Figures, geological maps, settlement data and land cover maps. The results based on these data show the number of areas affected by the eruption of Mount Agung, the data states that the data area with low vulnerability has an area of 0.001490 Ha. Medium vulnerability data has an eruption affected area of 47.024493897 Ha. While the high vulnerability has an affected area of 36.878843877 Ha. Differences in the level of vulnerability are influenced by social vulnerability, physical vulnerability, and environmental vulnerability.Keywords: Delineation, Eruption, GIS, Mount Agung, Vulnerability
