Abstract

Studi ini bertujuan mengembangkan Fondasi Digital Model statis sebagai prasyarat utama implementasi Digital Twin (DT) lereng di masa depan. Kebutuhan ini mendesak karena
model simulasi longsor tradisional (seperti SPH/FEM) memiliki efisiensi komputasi rendah, menghambat penilaian risiko real-time. Penelitian berfokus pada Pemodelan Geospasial 3D (Modul I) dengan memanfaatkan data elevasi nasional DEMNAS (sekitar 8 meter resolusi) dan mengolah Pemodelan Topografi 3D menggunakan tool open-source BlenderGIS untuk integrasi Pemetaan Tekstur Visual dari citra satelit. Kontribusi utama adalah perumusan metodologi
transposisi data satelit ke visualisasi 3D yang realistis, serta validasi akurasi geometris vertikal dari model DEMNAS. Ini membuktikan model ini andal sebagai fondasi geometris statis yang terjangkau dan tervalidasi untuk sistem Digital Twin selanjutnya

This study aims to develop a static Digital Model Foundation as a primary prerequisite for the future implementation of slope Digital Twins (DT). This development is urgently required because traditional landslide simulation models (such as SPH/FEM) suffer from low computational efficiency, which hinders real-time risk assessment. The research focuses on 3D Geospatial Modeling (Module I) by utilizing the national elevation data DEMNAS (approximately 8-meter resolution) and processing 3D Topographic Modeling using the open-source tool BlenderGIS to integrate Visual Texture Mapping from satellite imagery. The primary contribution of this study is the formulation of a methodology for transposing satellite data into realistic 3D visualizations, alongside the validation of the vertical geometric accuracy of the DEMNAS model. This proves that the proposed model is reliable as an affordable and validated static geometric foundation for subsequent Digital Twin systems.
