Abstract

Gelombang yang berasal dari laut dalam akan merambat menuju perairan dangkal dan mengalami perubahan, salah satunya membentuk gelombang pecah yang dipengaruhi oleh berkurangnya kedalaman. Gelombang pecah yang membentuk sudut terhadap garis pantai akan menimbulkan longshore current (arus sejajar pantai). Longshore current akan mengakibatkan tertranspornya sedimen di sepanjang pantai yang dapat menyebabkan terjadinya abrasi atau sedimentasi. Tujuan dari penelitian ini adalah untuk mengetahui mengetahui pengaruh longshore current terhadap  abrasi yang terjadi di Pantai Moro. Materi yang digunakan pada penelitian ini menggunakan data primer dan data sekunder. Data primer yang digunakan yaitu tinggi dan periode gelombang lapangan dan sedimen dasar. Sedangkan data sekunder menggunakan data angin ECMWF selama 10 tahun, Citra Landsat 7 dan 8, data debit sungai dan data pasang surut. Penentuan pengukuran gelombang lapangan dan lokasi sampel sedimen menggunakan metode purposive sampling. Untuk meramalkan tinggi dan periode gelombang pada setiap musimnya menggunkan metode SMB (Svendrup Munk Metode Bretchheider), dan untuk menghitung laju abrasi menggunakan metode DSAS. (Digital Shoreline Analysis System). Berdasarkan hasil penelitian menunjukkan  kecepatan longshore current pada musim barat sebesar 1,25038 m/s, pada musim peralihan 1 sebesar 0.71639 m/s, pada musim timur sebesar 1,08519 m/s, dan pada musim peralihan 2 sebesar 1,00732 m/s, yang menyebabkan abrasi dari tahun 2015-2016 seluas 7,29 ha. The waves which moves from deep sea into shallow water then changed into breaking waves that affected by decrease of the depth. The angel made from breaking waves towards coastline will be formed into longshore current. Longshore current caused sediment transported along the coast, this situation caused abration or sedimentation. The aim of this research was to determine the effect of longshore current towards abration in Pantai Moro. This research using both of primary and secondary data. In primary data, using wave height, period weight, and bed sediment. In secondary data, using ECMWF for wind data among 10 years, Landsat Imagery 7 and 8, river discharged, also tidal data. This research using purpose sampling method. Svendrup Munk Metode Bretchheider (SMB) method used to predict wave height and waves periode in every season, and Digital Shoreline Analysis System (DSAS) used to calculate the abration rate. The result showed the speed of longshore current in the west season was 1,25038 m/s, in the transition season 1 was 0.71639 m/s, in the east season was 1,08519 m/s, and in the transition season 2 was 1,00732 m/s, which causes abrasion from 2015-2016 an area of 7,92 ha.
