Studi Tentang Implementasi LiDAR Pada Perencanaan Jalan Tol Ruas Aceh-Sigli
Abstract
Jalan tol merupakan salah satu infrastruktur yang berperan untuk membantu meningkatkan perekonomian masyarakat. Melalui program Nawacita, Indonesia membangun infrastruktur jalan tol yang tersebar di seluruh daerah. Pada proses pembangunan jalan tol, diperlukan perencanaan jalur tol yang baik. Teknologi LiDAR merupakan salah satu teknologi penginderaan jauh yang mampu menghasilkan data point clouds obyek-obyek yang dipindai. Kumpulan data point clouds tersebut digunakan untuk membangun Digital Terrain Model (DTM) dan peta kontur. Pada penelitian bertujuan untuk melakukan studi terhadap implementasi teknologi LiDAR pada proses perencanaan jalur tol ruas Aceh-Sigli. Dari penelitian ini dihasilkan akurasi peta kontur yaitu 0.29. Berdasarkan standar Peraturan Badan Informasi Geospasial Nomor 6 Tahun 2018 tentang Pedoman Teknik Ketelitian Peta Dasar, peta kontur dengan interval 1 meter ini termasuk pada kategori peta RBI kelas 2. DTM yang dihasilkan dari penelitian ini mampu menyajikan kondisi topografi lokasi pembangunan jalan tol secara detail. Obyek-obyek yang mampu disajikan oleh DTM pada penelitian ini antara lain, obyek rumah, vegetasi, jaringan kabel, dan infrastruktur lainnya. Informasi obyek yang disajikan oleh DTM tersebut bermanfaat untuk mendesain jalur tol. Berdasarkan hasil penelitian ini, teknologi LiDAR dapat dimanfaatkan untuk memetakan kondisi topografi kawasan pembangunan jalan tol agar jalan tol yang dihasilkan memiliki kualitas yang baik.
Toll roads are one of the infrastructures that play a role in helping improve the community's economy. Through the Nawacita program, Indonesia builds toll road infrastructure spread throughout the region. In the toll road construction process, good toll lane planning is needed. LiDAR technology is a remote sensing technology capable of generating point clouds of scanned objects. The collection of point clouds is used to build a Digital Terrain Model (DTM) and contour maps. This study aims to conduct a study on the implementation of LiDAR technology in the planning process of the Aceh-Sigli toll road section. From this research, the accuracy of the contour map is 0.29. Based on the standards of the Geospatial Information Agency Regulation Number 6 of 2018 concerning Basic Map Accuracy Technical Guidelines, this contour map with 1-meter intervals is included in the RBI class 2 map category. The objects that can be presented by DTM in this study include houses, vegetation, cable networks, and other infrastructure. The object information presented by the DTM is useful for designing toll roads. Based on the results of this study, LiDAR technology can be used to map the topographic conditions of the toll road construction area so that the resulting toll road has good quality.
