Abstract
Penelitian ini memiliki tujuan untuk mengetahui kondisi komunitas ikan karang pada berbagai model terumbu buatan (Artificial Reef) di perairan Pantai Pasir Putih, Situbondo. Pengambilan data dilakukan pada 3 tipe terumbu buatan dengan bentuk kubus piramida (KP), kubus tersebar (KT) dan Reefball (RB), waktu pengamatan dilakukan sebanyak 3 kali selama 3 bulan. Hasil dari pengambilan data ikan karang pada ketiga terumbu buatan tersebut didapatkan sebanyak 72 spesies dengan komposisi terbanyak terdapat pada terumbu buatan RB sebanyak 44 spesies, sedangkan untuk kelimpahan tertinggi terdapat pada terumbu buatan KP dengan ditemukan 1243 individu. Seluruh spesies yang ditemukan termasuk kelompok yang memiliki sifat berasosiasi dengan ekosistem terumbu karang. Nilai keanekaragaman di ketiga lokasi tersebut termasuk sedang, berkisar antara 2,643-2,904. Didukung dengan nilai dominansi yang sangat kecil 0,077-0,108. Ketertarikan ikan pada terumbu buatan tersebut terlihat berkorelasi positif dengan jumlah lubang, panjang, tinggi dan volume dari terumbu buatan
