Abstract: | Duncanopsammia axifuga adalah karang yang termasuk ke dalam famili Dendrophyllidae dan termasuk spesies karang yang sangat jarang ditemukan. D. axifuga banyak ditemukan pada kedalaman lebih dari 20 meter, dan spesies ini biasa menempel pada substrat padat dengan area sekitarnya yang didominasi oleh substrat halus. Penelitian terbaru menunjukkan bahwa D. axifuga juga ditemukan pada kedalaman 5 meter di perairan pesisir Distrik Seget, Kabupaten Sorong,Provinsi Papua Barat. Perlu dilakukan kajian lebih lanjut terkait karateristik habitat D. axifuga pada lokasi tersebut, sebagai upaya melengkapi informasi ekologi D. axifuga yang termasuk dalam kategori biota near threatened. Pengamatan habitat
D. axifuga dilakukan dengan menggunakan metode underwater photo transect, dan kajian mikrohabitat dilakukan dengan metode purposive sampling pada 26 foto yang memliki koloni karang tersebut. Pengukuran koloni D. axifuga dilakukan dengan menggunakan software imageJ yang dilanjutkan dengan correspondence analysis untuk mengetahui asosiasi antara karang bercabang D. axifuga dengan
substrat dasar terumbu karang dan genus karang lain. Hasil penelitian menunjukkan bahwa karang D. axifuga memiliki habitat dengan tipe substrat dasar pasir, yang berasosiasi dengan dead coral with algae, makroalga, sponge, dan karang masif. Duncanopsammia axifuga is a coral that belongs to the Dendrophyllidae family and categorized as a coral species that rarely can be found. D. axifuga commonly can be found at depths of more than 20 meters, and this species usually attaches to hard substrates with soft substrates predominance. Recent studies have recorded that D. axifuga also can be found at 5 meters depth in the coastal waters of Seget District, Sorong Regency, West Papua Province. Further studies need to be carried out regarding the habitat characteristics of D. axifuga at this location to complete D. axifuga ecological information that categorized as near-threatened biota category. Observations of D. axifuga habitat carried out using underwater photo transect method and micro habitat studies were carried 26 photos that contain D. axifuga based on the purposive sampling method . Measurements of D. axifuga colonies were conducted using ImageJ software followed by correspondence analysis to determine the association between D. axifuga and the benthic community and also other living coral genera associated with D. axifuga. This research result shows that D. axifuga coral in the coastal waters of Seget District inhabits sandy bottom substrate that associated dead coral with algae, macroalgae, sponges, and live coral that is dominated by coral massive coral. |
