Abstract
Pelabuhan Tanjung Perak merupakan salah satu pintu gerbang Indonesia di Kawasan Bagian Timur, karena perannya yang sangat strategis menjadi pusat kolektor dan distributor barang ke Kawasan Timur Indonesia pada umumnya dan Provinsi Jawa Timur khususnya. Seperti pada umumnya pelabuhan yang masih aktif beroperasi, pelabuhan itu tentunya akan mengalami sedimentasi atau pendangkalan. Keberadaan sedimen yang tidak terkonsolidasi di dalam perairan akan mempengaruhi perbedaan interpretasi kedalaman yang akan berpengaruh terhadap perhitungan volume pengerukan. Survei batimetri menggunakan instrumen akustik dengan frekuensi yang berbeda diperlukan untuk mendapatkan gambaran endapan sedimen didasar laut. Instrumen akustik yang digunakan dalam penilitian ini adalah single beam echo sounder dual frequency. Data yang diolah adalah raw data single beam echo sounder dual frequency yang diakusisi oleh PT Pelindo III pada 30 Agustus sampai 04 September 2018 di perairan kolam pelabuhan Tanjung Perak Surabaya. Lokasi penelitian merupakan perairan yang digolongkan sebagai perairan dangkal. Hal ini dapat dilihat dari nilai kedalaman yang berkisar 0-12,8 m terhadap LWS. Perbedaan nilai kedalaman yang dideteksi oleh single beam eco sounder low frequency (38 kHz) dan high frequency (200 kHz) berbeda-beda pada setiap titik. Selisih deteksi kedalaman maksimal adalah 2,260 meter dan minimal adalah 0 meter. Sementara ketebalan endapan sedimen maksimal adalah 1,950 m dan minimal 0 m. Ketebalan endapan sedimen dasar laut dipengaruhi oleh kondisi morfologi dasar laut. Volume total ketebalan endapan sedimen adalah 59784,580 m3.

Tanjung Perak Port is one of the gateways of Indonesia in the Eastern Region, because its strategic role is to become a center for collectors and distributors of goods to Eastern Indonesia in general and East Java Province in particular. Like most ports that are still actively operating, the port will certainly experience sedimentation or siltation. Sedimentation can result in siltation in the port pond. The presence of unconsolidated sediments in the waters will affect differences in interpretation of depth which will affect the calculation of dredging volume. To get a picture of sediment deposits at the bottom of the sea, it is necessary to conduct bathymetry surveys with acoustic instruments with different frequencies. The acoustic instrument used in this research is a dual frequency single beam echo sounder. The processed data is a dual frequency raw single beam echo sounder data acquired by PT Pelindo III on August 30 to September 4, 2018 in the waters of the port of Tanjung Perak Surabaya. The research location is the waters classified as shallow waters. This can be seen from the depth values ranging from 0-12.8 m to LWS. Differences in depth values detected by a single beam eco sounder low frequency (38 kHz) and high frequency (200 kHz) differ at each point. The maximum difference in detection depth is 2.260 meters and a minimum is 0 meters. While the maximum thickness of sediment deposits is 1.950 m and a minimum of 0 m. The thickness of the seabed sediment deposits is influenced by the morphological conditions of the seabed. The total volume of overall sediment deposition thickness is 59784.580 m3 .
