Abstract

Pelabuhan Tanjung Perak memiliki beberapa terminal, yang salah satunya yaitu Terminal Nilam. Terminal Nilam merupakan Terminal Multipurpose dan salah satu terminal dengan tingkat kegiatan bongkar muat paling tinggi di Pelabuhan Tanjung Perak. Dengan tingginya tingkat kegiatan yang terjadi di Terminal Nilam diperlukan adanya kegiatan pemantauan dan perawatan kondisi dermaga agar kegiatan yang berlangsung dapat berjalan dengan lancar. Oleh karena itu, tujuan dari penelitian ini adalah mengidentifikasi kondisi dinding dermaga dengan pencitraan akustik menggunakan metode Oblique Side Scan Sonar serta memberikan gambaran tentang kondisi dari Dermaga Nilam. Untuk menghasilkan gambaran tentang dinding dermaga dengan citra akustik membutuhkan data Side Scan Sonar dimana pada saat instalasi alat diputar 90̊ sehingga menghadap ke dinding dermaga. Dalam penelitian ini dilakukan 3 macam koreksi yaitu Altitude Correction, Slant Range Correction, dan Time Varying Gain. Validasi dilakukan menggunakan kamera digital untuk meningkatkan kredibilitas dari hasil interpretasi citra Side Scan Sonar. Panjang dinding dermaga yang di survei adalah 268,62 meter dengan luas total sebesar 3223,44 m². Pada area tersebut terdapat tiga lokasi yang diinterpretasikan sebagai lubang pada dinding dermaga. Posisi lubang pertama pada koordinat UTM (Universal Transverse Mercator) Zona 49S A berada di (690268,97 m; 9203336,09 m) dengan luas sebesar 2,07 m², posisi lubang kedua berada di (690224,71 m; 9203404,98 m) dengan luas sebesar 1,91 m², dan untuk posisi lubang ketiga berada di (690208,15 m; 9203438,66 m) dengan luas 1,21 m². ======================================================== Port of Tanjung Perak has several terminals, one of which is Nilam Terminal. Nilam Terminal is a Multipurpose Terminal and one of the terminals with the highest loading and unloading activities at Port of Tanjung Perak. With the high level of activities occurring at the Nilam Terminal, monitoring and maintenance of the wharf wall conditions are needed, so that the ongoing activities can run smoothly. Therefore, the purpose of this study is to identify the condition of the wharf walls with acoustic imaging using the Oblique Side Scan Sonar apporach and provide an overview of the condition of the Nilam Terminal. To produce a picture of the wharf wall with an acoustic image requires Side Scan Sonar data, where during installation, the tool is turned 90̊ so that it faces the wharf wall. In this study, three types of corrections were made, which are Altitude Correction, Slant Range Correction, and Time Varying Gain. In order to validate the Side Scan Sonar result use digital cameras to increase the credibility of interpretation results. The length of the wharf wall surveyed is 268.62 meters with a total area of 3223.44 m². In that area there are three locations that are interpreted as holes in the wharf wall. The position of the first hole at the UTM (Universal Transverse Mercator) coordinates 49S A Zone is at (690268.97 m; 9203336.09 m) with an area of 2.07 m², the position of the second hole is at (690224.71 m; 9203404.98 m ) with an area of 1.91 m², and for the position of the third hole is (690208.15 m; 9203438.66 m) with an area of 1.21 m².
