Abstract
Pelabuhan Laut Sanur adalah pelabuhan pariwisata di Bali yang telah selesai dibangun pada November 2022. Pelabuhan ini memiliki berbagai komponen salah satunya adalah breakwater. Pembangunan breakwater tentu saja merubah morfologi pantai dan perubahan tersebut dapat berdampak pada perubahan pola arus dan pergerakan sedimen di area tersebut. Penulis melakukan penelitian tugas akhir untuk menganalisis perubahan morfologi pantai yang terjadi di Pantai Padang Galak sebelum dan setelah dibangunnya Breakwater Pelabuhan Sanur serta menentukan solusi yang tepat untuk menanggulangi masalah tersebut. Penelitan ini menggunakan metode numerik dengan bantuan Software Delft3D untuk mengetahui kondisi hidro-oseanografi. Pemodelan dilakukan dengan tiga kondisi yaitu Kalibrasi Pemodelan sebelum Dibangun Breakwater, Eksplorasi Pemodelan setelah Dibangun Breakwater, dan Eksplorasi Pemodelan Perencanaan Pelindung Pantai. Pemodelan dilakukan menyesuaikan kondisi lapangan dengan tingkat ketelitian mendekati asli yang divalidasi menggunakan metode Mean Percentage Error (MAPE). Data yang digunakan dalam pemodelan adalah data angin, pasang surut, arus, batimetri dan sedimen. Didapatkan perubahan morfologi pantai berupa sedimentasi dengan kondisi sebelum dan sesudah dibangunnya Breakwater Pelabuhan Sanur dengan rata-rata selisih volume sebesar 17.556 m³. Perencaan Pelindung Pantai berupa groin dengan panjang 54 m dan jarak antar groin 162 m diterapkan untuk mengatasi masalah tersebut. Hasil Pemodelan sebelum dan sesudah diterapkannya Rencana Bangunan Pelindung Pantai menunjukan pengurangan volume sedimen dengan rata-rata selisih volume sebesar 12.824 m³

Sanur Seaport is a tourism port in Bali which was completed in November 2022. This port has various components, one of which is a breakwater. The construction of a breakwater certainly changes the morphology of the beach and these changes can have an impact on changes in current patterns and sediment movement in the area. The author conducted a final project research to analyze the changes in coastal morphology that occurred at Padang Galak Beach before and after the construction of the Sanur Port Breakwater and determine the right solution to overcome the problem. This research uses numerical methods with the help of Delft3D Software to determine hydro-oceanographic conditions. Modeling is carried out with three conditions, namely Modeling Calibration before the Breakwater is Built, Modeling Exploration after the Breakwater is Built, and Exploration Modeling for Coastal Protection Planning. Modeling is carried out according to field conditions with a level of accuracy close to the original which is validated using the Mean Percentage Error (MAPE) method. The data used in the modeling are wind, tide, current, bathymetry and sediment data. Obtained changes in coastal morphology in the form of sedimentation with conditions before and after the construction of the Sanur Port Breakwater with an average volume difference of 17,556 m³. The Coast Protection Plan in the form of groynes with a length of 54 m and a distance between groynes of 162 m is implemented to overcome this problem. Modeling results before and after the implementation of the Coast Guard Building Plan showed a reduction in sediment volume with an average volume difference of 12,824 m³..e of 12.824 m³.
