Abstract

Pemecah gelombang merupakan salah satu bangunan pantai yang dibangun oleh manusia untuk melindungi wilayah pesisir seperti pelabuhan, pemukiman dan tempat wisata dari serangan gelombang. Penelitian ini bertujuan untuk mengetahui kondisi kerusakan unit pemecah gelombang BPPT – lock dengan lapisan tunggal dan ganda pada kepala pemecah gelombang tipe timbunan (rubblemound). Metode yang digunakan untuk melakukan penelitian ini adalah uji model fisik dan dilakukan di laboratorium Balai Teknologi Infrastruktur Pelabuhan dan Dinamika Pantai (BTIPDP) Yogyakarta – Indonesia. Model unit pemecah gelombang yang digunakan adalah BPPT – lock dengan berat 66.048 gram atau setara dengan 2.268 ton di prototipe, dan diuji di berbagai ketinggian gelombang, mulai dari 7.5 cm, 9.2 cm, 11.2 cm dan 11.4 cm dengan periode tetap sebesar 1.5 detik atau setara dengan 2.85 m, 3.496 m, 4.256 m dan 4.332 m di prototipe. Berdasarkan hasil pengujian di laboratorium, disarankan untuk memasang lapisan pelindung ganda karena persentase kerusakan lapisan pelindung ganda lebih rendah dan koefisen kerusakan (KD) lebih tinggi.

Breakwater is one of the coastal structures built by humans to protect coastal areas such as ports, settlements, and tourist attractions from wave attacks. This test aims to determine the condition damage of BPPT – lock in one- and two-layers placements in the head of the rubble mound breakwater. The method used to conduct this research was physical model test and carried out at laboratory of Balai Teknologi Infrastruktur Pelabuhan dan Dinamika Pantai (BTIPDP) Yogyakarta – Indonesia. The armour unit model used BPPT–locks were 66.048 grams or equivalent to 2.268 tons in prototype and tested in various wave heights, starting from 7.5 cm, 9.2 cm, 11.2 cm and 11.4 cm with period 1.5 S or equal to 2.85 m, 3.496 m, 4.256 m and 4.332 meters of wave height in the prototype. Based on the laboratory results of testing, installing a double armour layer was recommended because the percentage of damage of the double armour layer was lower, and the coefficient of damage (KD) was higher.
