Abstract
Pelabuhan Tanjung Perak Surabaya merupakan salah satu pelabuhan di Indonesia yang menjadi pusat distributor barang ke kawasan timur Indonesia. Keberadaan sedimen di dalam perairan akan mempengaruhi kondisi fisik perairan pelabuhan tersebut dikarenakan pengendapan sedimen di suatu perairan akan mempengaruhi bentuk topografi di dasar perairan. Pengerukan secara rutin diperlukan untuk memelihara kedalaman suatu kolam dan alur pelayaran dari pendangkalan akibat pergerakan dan pengendapan material sedimen. Salah satu penyebab dari proses sedimentasi adalah arus dan pasang surut air laut. Pasang surut adalah fluktuasi muka air laut karena adanya gaya tarik benda-benda di langit, terutama matahari dan bulan terhadap massa air laut di bumi.
Dalam hal ini dilakukan analisis pola sebaran sedimen menggunakan pemodelan hidrodinamika 3D menggunakan perangkat lunak Delft3D. Pemodelan arus dan sebaran sedimen dilakukan menggunakan metode simulasi numerik dengan parameter data batimetri, pasang surut air laut, river discharge, densitas, dry density dan konsentrasi sedimen. Dari penelitian ini didapatkan hasil nilai kecepatan arus paling tinggi saat periode spring dan neap tide adalah 1,3 m/s. Berdasarkan data kumulatif erosi dan sedimentasi, daerah perairan Pelabuhan Tanjung Perak yang mengalami sedimentasi paling besar adalah kolam pelabuhan, Terminal Teluk Lamong dan daerah sekitar bangunan jetti, sehingga diperlukan monitoring secara rutin di daerah tersebut

Tanjung Perak Port in Surabaya is one of the biggest ports in Indonesia. This port becomes the center of goods distribution to the eastern region in Indonesia. The presence of sediments at port vicinity area will affect the phisical condition of its water. Thus, the sediment deposition alters the seabed topography. Routine dredging is required to maintain the depth of a port basin and the access channel from shoaling due to the movement and deposition of sediment materials. Two of the causes of the sedimentation process are the currents and tides. Tides are sea level fluctuations due to the attraction of objects in the sky, especially the sun and moon to the mass of sea water on earth.
In this case, the pattern of sediment distribution analyzed using 3D hydrodynamic modeling with Delft3D software. Current and sediment distribution modeling are performed using numerical simulation method with parameters of bathymetric data, sea tides, river discharge, sediment density, sediment dry density, and sediment concentration. Based on this research, the highest current velocity value during the spring tide and neap tide period is 1.3 m/s. The maximum cumulative erosion and sedimentation in the waters of Tanjung Perak Port is the port basin, Lamong Bay Terminal and the area around the jetty building. Consequently, in these location should be monitored frequently.
