Abstract

Pelabuhan Bakauheni merupakan salah satu pelabuhan di Indonesia yang berlokasi di kecamatan Bakauheni, Kabupaten Lampung Selatan. Penggunaan transportasi berbasis jalan rel dirasakan sangat efektif dan efisien dalam melayani tingginya tuntutan kebutuhan pergerakan dikarenakan transportasi berbasis jalan rel memiliki kapasitas dan kecepatan yang lebih tinggi dibandingkan transportasi berbasis jalan raya. Penelitian ini dilakukan dengan tujuan mendesain geometri jalan rel Bakauheni-Sidomulyo dan mendesain drainase jalan rel. Geometri jalan rel didesain berdasarkan pada beban lintas yang merupakan turunan dari jumlah demand angkutan eksiting dan tipe kereta yang melintasinya dengan mempertimbangkan faktor keamanan, kenyamanan, ekonomi dan lingkungan. Pada perancangan jalan rel ini menggunakan jalan rel dengan kelas jalan I dengan double track dan lebar sepur 1435mm sepanjang 39,173 km. Jalan rel ini direncanakan dengan 7 lengkung horisontal (dengan jari-jari 1400m) yang menggunakan tipe lengkung Spiral Circle Spiral (SCS) dan 6 lengkung vertikal (dengan jari-jari minimum 15736,5 m). Struktur jalan rel ini terdiri dari rel R60, penambat elastic ganda, bantalan beton, tebal balas 30 cm dan sub balas 30 cm. Drainase samping di buat seragam dengan bentuk segi empat dengan dimensi lebar x tinggi yaitu 50 x 30 cm, tinggi jagaan 38,7 cm. Penampang gorong-gorong yang digunakan berbentuk lingkaran dengan diameter seragam sebesar 0,60m.

Abstract

Recovery efforts following a disaster can be slow and painstaking work, and potentially put responders in harm's way. A system which helps identify defects in critical building elements (e.g., concrete columns) before responders must enter a structure can save lives. In this paper we propose a system, centered around an image based three-dimensional (3D) reconstruction method and a new 3D crack detection algorithm. The image-based method is capable of detecting and analyzing surface damages in 3D. We also demonstrate how the robotics can be used to gather the images from which the reconstruction is created, further reducing the risk to responders. In this regard, image-based 3D reconstructions represent a convenient method of creating 3D models because most robotic platforms can carry a lightweight camera payload. Additionally, the proposed 3D crack detection algorithm also provides the advantage of being able to operate on 3D mesh models regardless of their data collection source. Our experimental results show that 3D crack detection algorithm performs well constructions, successfully identifying cracks, reconstructing 3D profiles, and measuring geometrical characteristics on damaged elements and not finding any cracks on intact ones.
