Abstract

Breakwater adalah salah satu bangunan pelindung pantai yang digunakan untuk meredam gelombang yang datang menuju pantai. Fungsi dari lapisan pelindung yang terdapat pada breakwater yaitu meredam gelombang datang kemudian mentransmisikannya menjadi gelombang yang lebih kecil sehingga tidak mempengaruhi kondisi dibelakangnya. Penelitian ini bertujuan untuk menguji stabilitas unit lapisan pelindung pada breakwater. Penelitian ini menggunakan metode uji model fisik di laboratorium dengan 2 variasi periode gelombang yaitu 1,15 s dan 1,5 s, 4 variasi tinggi gelombang yaitu 10,1 m, 9,2 m, 7,4 m, dan 6,4 m, serta 4 variasi unit lapisan pelindung yaitu Hexaloc, Tetrapod, BPPT-Loc, dan Batu Pecah. Analisis stabilitas menghasilkan nilai presentase kerusakan terbesar untuk Hexaloc, Tetrapod, BPPT-Lock, dan Batu Pecah secara berurutan yaitu 11,10%, 10,57%, 0,16%, dan 2,33%. Didapatkan pula hasil model regresi linear berganda untuk memberikan nilai prediksi bilangan stabilitas yaitu NS=1,732+0,051(KD)+28,938(H/(gT^2))

A breakwater is a coastal structure used to dampen incoming waves towards the shore. The function of the protective layer on a breakwater is to absorb incoming waves and transmit them as smaller waves, thus preventing any significant impact on the area behind it. This study aims to test the stability of protective layer units on a breakwater. The research employed a physical model test method in the laboratory with two wave period variations (1.15 s and 1.5 s), four wave height variations (10.1 m, 9.2 m, 7.4 m, and 6.4 m), and four protective layer unit variations (Hexaloc, Tetrapod, BPPT-Lock, and Rubble Mound). Stability analysis showed the highest damage percentages for Hexaloc, Tetrapod, BPPT-Lock, and Batu Pecah in sequence: 11.10%, 10.57%, 0.16%, and 2.33%. A multiple linear regression model was also derived to provide a predictive value for the stability number, which is: NS=1,732+0,051(KD)+28,938(H/(gT^2))
