Abstract
English
Breakwaters are highly effective breakwater constructions that can be used to protect harbor waters by interrupting wave energy coming from the deep sea. Widely used breakwaters today are of the pile type, both natural and artificial. The drawback of rock breakwaters is that they are large in size and therefore very expensive to issue. Therefore, a new type of breakwater is needed that is smaller in size and cheaper to build. One solution that can be applied is a suspended breakwater. The purpose of this study is to determine the effect of wave parameters on the coefficient of wave transmission through a suspended breakwater. The research was conducted at the Marine Technology Research Laboratory, Hasanuddin University. The parameters in this study were carried out with 5 variations of wave height, 5 variations of wave period (T), and 3 variations of model length (L). From the results of the research we have done, it can be concluded that the value of the transmission coefficient (Kt) is inversely proportional to the steepness of the wave (Hi/L). Figure 3 shows that when compared between model variations (L1 = 40 cm; L2 = 50 cm; and L3 = 60 cm) with depth conditions (d = 70 cm) and with period variations (T 1; T 1.2; T 1.5; T 1.8 and T2 s), it can be seen that the Kt value is lower in the third model variation, L3 = 60 cm with a value of 0.095 < Kt < 0.53.

Pemecah gelombang merupakan konstruksi pemecah gelombang yang sangat efektif yang dapat digunakan untuk melindungi perairan pelabuhan karena dapat mengganggu energi gelombang yang berasal dari laut dalam. Pemecah gelombang yang banyak digunakan saat ini adalah jenis tiang pancang, baik alami maupun buatan. Kelemahan pemecah gelombang batuan adalah ukurannya yang besar dan oleh karena itu sangat mahal untuk diterbitkan. Oleh karena itu, diperlukan pemecah gelombang jenis baru yang ukurannya lebih kecil dan biaya pembangunannya lebih murah. Salah satu solusi yang dapat diterapkan adalah pemecah gelombang tersuspensi. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh parameter gelombang terhadap koefisien transmisi gelombang melalui hanging breakwater. Penelitian dilakukan di Laboratorium Riset Teknologi Kelautan Universitas Hasanuddin. Parameter dalam penelitian ini dilakukan dengan 5 variasi tinggi gelombang, 5 variasi periode gelombang (T), dan 3 variasi panjang model (L). Dari hasil penelitian yang telah kami lakukan dapat disimpulkan bahwa nilai koefisien transmisi (Kt) berbanding terbalik dengan kecuraman gelombang (Hi/L). Dari gambar 3 menunjukkan bahwa apabila dibandingkan antara variasi model (L1 = 40 cm; L2 = 50 cm; dan L3 = 60 cm) dengan kondisi kedalaman (d = 70 cm) dan dengan variasi periode (T 1; T 1,2; T 1,5; T 1,8 dan T2 dtk) maka dapat dilihat bahwa nilai Kt condong lebih rendah pada variasi model ke tiga yaitu L3 = 60 cm dengan nilai 0,095 < Kt < 0,530 dan L2 = 0,108 < Kt < 0,608 serta L1 = 0,163 < Kt < 0,584. Hal ini menunjukkan bahwa Pemecah Gelombang tipe hanging breakwater lebih efektif jika semakin lebar model uji yang diberikan.
