Plugin QGIS "Landslide & Erosion" adalah perangkat lunak analisis spasial terintegrasi untuk menilai kerentanan bencana geologi, berupa tanah longsor, likuefaksi, dan erosi tanah di wilayah Indonesia melalui tiga tab utama. Tab Landslide & Liquefaction mengunduh data gempa USGS (ShakeMap) beserta model probabilitas pemicu longsor, dan untuk likuefaksi, melakukan overlay multi-kejadian, serta menganalisis dampaknya terhadap populasi per wilayah; tab Erosion USLE menghitung laju erosi dengan metode Universal Soil Loss Equation (A = R×K×LS×C×P) berbasis standar SK Menteri LH No. 12/1995 yang diklasifikasikan menjadi lima kelas bahaya, dilengkapi analisis Tingkat Bahaya Erosi (TBE) per kedalaman solum tanah; dan tab Erosion SMCE menentukan indeks kerentanan erosi menggunakan metode Multi-Criteria Evaluation berbobot (kemiringan, curah hujan, jenis tanah, penutupan lahan, dan jarak dari sungai). Setiap hasil dikeluarkan dalam bentuk raster GeoTIFF dan shapefile analisis dampak yang telah terstandarisasi, sehingga peta siap langsung digunakan untuk perencanaan mitigasi bencana, tata ruang, maupun pelaporan resmi tanpa pengolahan lanjutan.

The QGIS “Landslide & Erosion” plugin is an integrated spatial analysis software tool designed to assess geological hazard susceptibility, including landslides, liquefaction, and soil erosion, across Indonesia through three main tabs. The Landslide & Liquefaction tab downloads USGS earthquake data (ShakeMap) together with triggering probability models (Jessee et al., 2018 for landslides and Zhu et al., 2017 for liquefaction), performs multi-event overlay analysis, and assesses potential impacts on populations by administrative area. The Erosion USLE tab calculates soil erosion rates using the Universal Soil Loss Equation (A = R × K × LS × C × P), based on the standards established in the Indonesian Minister of Environment Decree No. 12/1995. The resulting erosion rates are classified into five hazard classes and complemented by an analysis of the Erosion Hazard Level (Tingkat Bahaya Erosi/TBE) according to soil solum depth. Meanwhile, the Erosion SMCE tab determines an erosion susceptibility index using a weighted Multi-Criteria Evaluation approach that incorporates slope, rainfall, soil type, land cover, and distance from rivers within a 10-meter overlay grid. All analytical outputs are generated as standardized GeoTIFF raster files and impact-analysis shapefiles, producing ready-to-use maps for disaster mitigation planning, spatial planning, and official reporting without requiring further data processing.
