Abstract

Gapura Wringin Lawang merupakan salah satu cagar budaya peninggalan Kerajaan Majapahit yang terletak di Trowulan, Mojokerto. Untuk mendukung pelestariannya, diperlukan dokumentasi digital dalam bentuk model tiga dimensi (3D) yang presisi. Penelitian ini bertujuan untuk menghasilkan model 3D Gapura Wringin Lawang melalui integrasi data point cloud dari sensor aktif LiDAR berbasis UAV (Unmanned Aerial Vehicle) dan Terrestrial Laser Scanner (TLS). Akuisisi data dilakukan menggunakan DJI Matrice 350 RTK dengan sensor Zenmuse L2 dan alat TLS Leica RTC360. Registrasi data point cloud menggunakan metode Cloud to Cloud, dengan pengolahan menggunakan perangkat lunak Cyclone Register 360, DJI Terra, dan Cloud Compare. Hasil integrasi data point cloud UAV dan TLS menghasilkan total 115.261.884 titik, yang kemudian diolah menjadi model mesh 3D dengan 6.506.902 faces. Hasil pengujian akurasi geometrik terhadap data pengukuran lapangan menunjukkan nilai Root Mean Square Error (RMSE) sebesar 0,008 meter, yang mencerminkan deviasi kecil dan menunjukkan ketelitian tinggi. Hal ini menunjukkan bahwa model 3D yang dihasilkan memiliki kesesuaian dimensi spasial yang baik dengan kondisi aktual. Dibandingkan dengan sensor kamera, model berbasis sensor LiDAR menunjukkan keunggulan dalam akurasi dan detail struktur bangunan, meskipun tekstur visual dari sensor kamera tampak lebih realistis. Secara keseluruhan, hasil penelitian ini menunjukkan bahwa integrasi LiDAR UAV dan TLS dapat menjadi solusi efektif untuk dokumentasi digital cagar budaya dalam bentuk model 3D.

Wringin Lawang Gate is one of the cultural heritage sites from the Majapahit Kingdom located in Trowulan, Mojokerto. To support its preservation, precise digital documentation in the form of a three-dimensional (3D) model is required. This study aims to produce a 3D model of the Wringin Lawang Gate through the integration of point cloud data from active LiDAR sensors based on UAV (Unmanned Aerial Vehicle) and Terrestrial Laser Scanner (TLS). Data acquisition was conducted using the DJI Matrice 350 RTK equipped with a Zenmuse L2 sensor and the Leica RTC360 TLS device. Point cloud data registration was performed using the Cloud-to-Cloud method, with processing carried out using Cyclone Register 360, DJI Terra, and Cloud Compare software. The integration of UAV and TLS point cloud data resulted in a total of 115.261.884 points, which were then processed into a 3D mesh model with 6.506.902 faces. Geometric accuracy testing against field measurements showed a Root Mean Square Error (RMSE) value of 0,008 meters, indicating minimal deviation and high precision. This demonstrates that the resulting 3D model has good spatial dimensional accuracy in representing actual conditions. Compared to camera sensors, the LiDAR-based model exhibits superior accuracy and structural detail, although the visual texture captured by camera sensors appears more realistic. Overall, the results of this study show that the integration of UAV and TLS LiDAR can be an effective solution for digitally documenting cultural heritage sites in the form of 3D models.
