Abstract
In recent years, a series of ambitious infrastructure projects have been carried out in Indonesia, generating positive impacts on various aspects of society and the national economy. One of these strategic projects is the Bagong Dam Project, located in the villages of Sumurup and Sengon, Bendungan District, Trenggalek Regency, approximately 10 km north of the city center. This project is managed by the Brantas River Basin Authority (BBWS Brantas) with a contract value of IDR 1.6 trillion. The dam construction is divided into two work packages. In the modern construction era, a system called Building Information Modeling (BIM) has emerged, enabling better integration between stakeholders and construction service providers. One of the technologies supporting BIM implementation is the use of unmanned aerial vehicles (UAVs), or drones. Drones equipped with advanced sensors can generate point clouds that allow the creation of accurate digital models. The most commonly used method in this process is photogrammetry, which relies on processing a series of 2D images to construct precise 3D models. In the Bagong Dam Project Package II, digital mapping using the photogrammetry method was conducted across all work locations, especially on the spillway structure. This study uses a comparative analysis method by evaluating the coordinate values obtained from the photogrammetry method against those from the triangulation method. This comparison aims to determine the level of accuracy photogrammetry can achieve when using a limited number of reference points. When comparing distances between eight points measured using the triangulation method with measurements from Google Earth, the results showed a relatively small error ratio. This suggests that the triangulation results are nearly as accurate as those from Google Earth for general visual assessments. The Root Mean Square Error (RMSE) of the additional coordinates processed using Agisoft Metashape and the triangulation method falls within the category of general mapping, with a value of 2.95 meters. These findings indicate that photogrammetry in the Bagong Dam Project Package II can be effectively carried out using only four Ground Control Points (GCPs) and 24 documentation data points.
