Abstract
Pelabuhan Tanjung Perak Surabaya menjadi salah satu gerbang transportasi barang di Indonesia Timur yang memiliki beberapa terminal dengan fungsi yang berbeda-beda. Salah satu terminal yang berfungsi sebagai terminal multipurpose di Pelabuhan Tanjung Perak adalah Terminal Teluk Lamong. Dengan semakin meningkatnya kegiatan transportasi laut di Terminal Teluk Lamong, maka dilakukan pemeliharaan secara berkala untuk menjaga kedalaman ideal yang sesuai dimensi dan ukuran kapal yang berlabuh di perairan Terminal Teluk Lamong. Supaya proses pemeliharaan pelabuhan berjalan efektif diperlukan pengetahuan mengenai analisis pola sebaran dan ketebalan sedimen penyusun di lokasi tersebut. Dalam penelitian ini dilakukan pembuatan model ketebalan sedimen dari data sub bottom profiler dan pola sebaran sedimen menggunakan data side scan sonar serta sampel uji bor yang digunakan untuk uji validasi setelah dilakukannya interpretasi. Berdasarkan hasil pengolahan dan analisis dihasilkan bahwa Kolam dermaga Teluk Lamong memiliki nilai kedalaman yang berkisar antara 8 meter hingga 20 meter terhadap LWS dengan ketebalan sedimen rata-rata senilai 2.0795 meter, ketebalan maksimal sebesar 2,6978 meter dan ketebalan minimum 0,9391 meter. Penumpukan lapisan sedimen pada permukaan dasar laut di wilayah kolam dermaga Teluk Lamong cenderung mengikuti struktur topografi atau relief dari dasar laut. Sementara dari hasil analisis peta sebaran sedimen di Teluk Lamong menggunakan data side scan sonar diperoleh luasan total perhitungan terhadap lokasi sebesar 116.531,3297 m2, luasan sedimen dengan tekstur kasar sebesar 12.821,6647 m2, tekstur sedang sebesar 79.711,8928 m2, dan tekstur halus sebesar 23.997,7722 m2 dimana sedimen didominasi oleh jenis sedimen pasir.

Tanjung Perak Port is one of the goods and commodities transportation gateways in Eastern Indonesia which locate in Surabaya has several terminals with different functions. One terminal that serves as a multipurpose terminal at Tanjung Perak Port is Lamong Bay Terminal. With the increasing amount of sea transportation activities at Lamong Bay Terminal, maintenance is carried out periodically to keep the ideal depth that matches the dimensions and size of the ships anchored in the waters of Lamong Bay. In order for the port maintenance process to run effectively, knowledge is needed regarding the analysis of the distribution and thickness of sediments in related location. In this study, the sediment thickness model was made from sub bottom profiler data and for the sediment distribution using side scan sonar data. The borelog sample is used for validation tests after the interpretation. Based on the results of the processing and analysis, it was found that Lamong Bay has a depth value ranging from 8 meters to 20 meters towards LWS with an average sediment thickness of 2.0795 meters, maximum thickness of 2.6978 meters and a minimum thickness of 0.9391 meters. The accumulation of sediment layers on the surface of the sea floor around the Lamong Bay dock pool area tends to follow the topographic structure or relief from the seabed. While the results of the sediment distribution analysis in Lamong Bay using side scan sonar data obtained the total calculation area of 116531.3297 m2 which has the sediment area with a rough texture of 12821.6647 m2 , area with medium texture of 79711.8928 m2 , and area with fine texture of 23997.7722 m2 where the research area is dominated by sand.
