This study aims to provide information about coral reefs condition in Poopoh waters and as input For related stakeholders for future coral reef management and conservation. Data sampling employed SCUBA gear with Line Intercept Transect (LIT) at 3 M and 10 M depth. It used 30 M-transect line and each depth was laid 3 transects.Results showed that the highest number of hard coral colonies at 3 M depth was found in branching coral and the lowest in ACD, while at 10 M depth, the highest number of colonies was recorded in CMR and the lowest in ACB.  Based on percent cover, it was found that the depth of 3 M had moderate coral condition, while the depth of 10 M had poor condition. Both depths had low diversity index, high eveneness index, and low dominance index.Key words: coral reef condition,  percent cover, diversity, evenness, dominance.  ABSTRAKPenelitian ini bertujuan untuk memberikan informasi tentang kondisi terumbu karang di perairan Desa Poopoh sebagai masukan bagi pihak-pihak terkait untuk pengelolaan dan pelestarian terumbu karang di masa mendatang.Pengambilan data terumbu karang menggunakan alat SCUBA dengan metode LIT (Line Intercept Transek) pada kedalaman 3 M dan 10 M. Penelitian in menggunakan 30 M panjang  transek, dan masing-masing kedalaman ditempatkan 3 transek.Jumlah koloni karang batu terbanyak di kedalaman 3 meter ditemukan pada jenis karang bercabang (CB), 4,33 koloni dan jumlah koloni terendah pada ACD, sedangkan pada kedalaman 10 M, koloni terbanyak ditemukan CMR dan terendah pada ACB.  Berdasarkan persentase tutupan, ditemukan bahwa kedalaman 3 meter memiliki kondisi terumbu karang sedang, sedangkan kedalaman 10 M memiliki kondisi terumbu karang buruk. Kedua kedalaman memiliki indeks keanekaragaman (H’) rendah, indeks kemerataan tinggi, dan indeks dominasi tergolong rendah.Kata kunci: kondisi terumbu karang, persen tutupan, keragaman, pemerataan, dominasi.

The information on population structure of Acanthaster planci in Bunaken National Park (BNP) is urgent to be presented in order to be considered in decision making especially on coral reef management in BNP. The objectives of  this study was to examine the  population structure of A. planci, represented by the diameter and weight, number of arms, while the density, distribution and types of coral predation by reef animals in the Southern part of Bunaken Island also observed. Data were collected at the three locations namely, front reef flat (FRF), middle reef flat (MRF) and back reef flat (BRF) with total coverage area of ​​100 x 50 meters. Sixty two individuals (41 at night and 21 at day time) were found with a body diameter ranging between 14 – 28 cm, whereas body weight ranged from 80 – 700 gr, with the number of arms between 9 until 17. The density of A. planci during day time was 0.0042 ind/m2, while the night time was 0.0082 ind/m2, moreover the animal is generally spread aggregated. The results of this study indicated that the population of A. planci in BNP was an adult population with density is still relatively normal, despite an alert sign for the sustainability of coral reef ecosystems in the BNP.
