| Summary: | Lebak Regency, located in Banten Province, is an area prone to various types of
natural disasters, particularly landslides. The geographical characteristics of this
regency, which consist of hilly and mountainous regions, combined with high rainfall,
significantly increase the risk of landslides. The impacts of these disasters not only
cause loss of life and economic losses but also damage infrastructure and buildings.
Therefore, in this project, accurate identification of building damage is carried out to
enable proper disaster evaluation.
The initial process involves identifying land movement phenomena derived from InSAR
data to determine high-risk areas. Subsequently, field surveys are conducted to
validate the identified areas, resulting in the selection of Cikulur District for further
analysis. To determine the detailed impact of building damage, LiDAR and TLS point
cloud data are integrated with the MTs Ar-Ribathiyyah Cikulur object. From the
integration of these two point cloud sources, an RMSE of 0.265 mm was obtained. The
results of this integration will be used to create a 3D BIM model.
The 3D BIM model has a depth of detail and information at LOD300, including
attribute information on the condition of the building, such as the results of the
verticality analysis of the building. This allows for a quantitative assessment of the
building's feasibility.
