Abstract

Penelitian ini mengenai Studi Ketelitian Planimetrik pada permukaan (3D) model dalam survei tiga dimensi menggunakan terrestrial laser scanning (TLS). Jembatan Suramadu yang berlokasi di antara Kota Surabaya dan Kabupaten Bangkalan sebagai penghubung Pulau Jawa dengan Pulau Madura ini terpilih sebagai objek penelitian. Instrumen teknologi laser yang digunakan sebagai pembanding adalah Geomax Zoom 300 (Terrestrial Laser Scanner) dan Ruide RTS-822 R3 (Electronic Total Station) serta GPS Geodetik Topcon-Hiper Pro untuk pengukuran titik referensi (BM) dan sebagai pedoman titik koordinat georeferensi. Dua puluh titik ada pada posisi yang sama di masingmasing model permukaan pengukuran yang dipilih. Koordinat hasil pengukuran Electronic Total Station dan Terrestrial Laser Scanner kemudian diubah menjadi koordinat global (UTM) menggunakan proses georeferensi hasil pengukuran GPS Geodetik. Koordinat 3D dan ketinggian Jembatan Suramadu dihitung untuk setiap model. Perbedaan jarak koordinat dan ketinggian dianggap sebagai kesalahan dalam x, y, dan z. Standar deviasi perbedaan jarak koordinat 3D adalah x = 0.240119501 m, y = 0.299053305 m, and z = 0.172432871 m.. Dengan interval kepercayaan 90% pada uji statistik, beberapa perbedaan jarak tidak jatuh dalam kisaran toleransi (sekitar 10 %).. 3D visualisasi ketinggian Jembatan Suramadu yang dihasilkan dari data Terrestrial Laser Scanner lebih tepat daripada yang dibuat dari data Total Station. Di masa depan, 3D seperti visualisasi model permukaan dapat digunakan untuk dokumentasi, pelestarian dan rekonstruksi bangunan jembatan.========== Research subjects reported was the study on model of threedimensional (3D) surface model of Suramadu Bridge in threedimensional using terrestrial laser scanning (TLS). Longest bridge located between Surabaya and Bangkalan as connecting Java and Madura was chosen as the research object. Laser technology instruments used for comparison is GeoMax Zoom 300 (Terrestrial Laser Scanner) and Gowin TKS-202 (Electronic Total Station) as well as geodetic GPS coordinates for the reference measurement and the longest bridge georeferenced. Ten points there are in the same position in each of the measurement surface model chosen. Coordinate measurement results Electronic Total Station and Terrestrial Laser Scanner is then converted into a global coordinates (UTM) using georeferencing process Geodetic GPS measurement results. 3D coordinates and altitude longest bridge is calculated for each model. Coordinate distance and altitude difference is regarded as an error in the x, y, and z. The standard deviation of the differences within the 3D coordinates are x = 0.240119501 m, y = 0.299053305 m, and z = 0.172432871 m. With a= 90% confidence interval on statistical tests, some distance difference does not fall within the tolerance range (about 10%) .. 3D visualization height Suramadu generated from the data Terrestrial Laser Scanner more precise than those made of the data Total Station. In the future, such as the visualization of 3D surface models can be used for documentation, preservation and reconstruction of bridge building.
