Abstract
Struktur pelindung pantai yang efektif semakin dibutuhkan untuk mereduksi energi gelombang sekaligus menjaga keberlanjutan ekosistem pesisir, sehingga terumbu buatan berkembang sebagai alternatif yang menggabungkan fungsi proteksi dan rehabilitasi. Dalam penelitian ini, hexagonal artificial reef (Hexareef) dipilih karena bersifat modular, memiliki kestabilan geometrik yang baik, serta menyediakan peluang penguatan melalui mekanisme saling mengunci sehingga susunan lebih kompak dan tahan terhadap beban hidrodinamika. Penelitian ini mengevaluasi kinerja Hexareef melalui uji model fisik dengan fokus pada transmisi gelombang, stabilitas susunan, dan distribusi gaya. Pengujian dilakukan pada variasi susunan tiga lapis (631 dan 731), tipe single dan grup, dengan orientasi serangan gelombang pada sisi lebar dan runcing, untuk kondisi berkait dan tak berkait pada tiga elevasi muka air (LWS, MSL, dan HWS) dengan tiga variasi tinggi gelombang (H5, H10, dan H15) berdasarkan kesebangunan Froude skala 1:15. Transmisi dievaluasi menggunakan

Effective coastal protection structures are increasingly required to reduce wave energy while sustaining coastal ecosystems, motivating the development of artificial reefs that combine wave protection with marine rehabilitation. In this study, a hexagonal artificial reef (Hexareef) was selected for its modularity, geometric stability, and potential to enhance structural integrity through an interlocking mechanism that improves compactness and resistance to hydrodynamic loading. This study evaluates Hexareef's performance through physical model tests in a wave flume, focusing on wave transmission, structural stability, and force distribution. Experiments covered three layers (631 and 731) configurations with single and group arrangements, incoming wave orientation at broadside and tapered reef configuration, tested for interlocking versus non-interlocking systems under three water levels (LWS, MSL, HWS) and three wave cases (H5, H10, H15) based on Froude similarity at a 1:15 scale. Wave transmission was quantified using incident and transmitted wave heights (
