Abstract

Pantai di Kabupaten Tangerang, Provinsi Banten mempunyai bentang yang sangat panjang dengan garis pantai ±51 km. Di kawasan pesisir Pantai Kabupaten Tangerang terdapat obyek wisata yang terkenal seperti Pantai Tanjung Pasir dengan garis pantai ± 22 km. Untuk menjaga garis pantai ini, dilakukan analisis lanjutan untuk mengidentifikasi kerusakan yang akan terjadi. Penelitian ini bertujuan untuk mengetahui perubahan garis pantai selama 10 tahun menggunakan program GENESIS (Generalized Model for Simulating Shorline Change). Berdasarkan hasil analisis dan pemodelan pada Pantai Tanjung Pasir di Kabupaten Tangerang, Provinsi Banten (dengan f =2,185) termasuk dalam tipe campuran dominan diurnal dimana satu hari cenderung 2 (dua) kali pasang surut dengan ketinggian muka air yang berbeda dengan fetch efektif sebesar 526,61 km, sedangkan analisis tinggi gelombang dan periode gelombang di dapat dari data angin dengan menggunakan Metode Fisher Tippet Type – I dan Metode Weibull. Perubahan garis pantai dapat di perkirakan dengan melaksanakan simulasi numerik dengan menggunakan model model perubahan satu garis (one line model). Pemodelan garis pantai dilakukan dengan jumlah grid sebanyak 98 dengan jarak antar grid (dx) sebesar 90 m. Input gelombang didapatkan dari hasil analisa data angin maksimum bulanan selama 10 tahun. Dari hasil pemodelan GENESIS pada kawasan Pantai Tanjung Pasir, Kabupaten Tangerang, Provinsi Banten, terlihat adanya pergerakan sedimentasi pantai baru pada grid 26 – 34 terjadi erosi yang begitu maksimum pada grid 29 dengan perubahan sejauh 520 m.
