Abstract

Penelitian ini berjudul “Keanekaragaman Terumbu Karang dan Perbedaan Respon Terhadap Bleaching Ditinjau dari Bentuk Pertumbuhannya (Lifeform) di Taka Tengah Taman Laut Karimunjawa” dilakukan untuk mengetahui keanekaragaman terumbu karang berdasarkan bentuk pertumbuhan terumbu karang (lifeform), perbedaan respon terumbu karang terhadap bleaching berdasarkan bentuk pertumbuhan (lifeform) serta kondisi terumbu karang berdasarkan tutupan karang hidup di Taka Tengah, Taman Laut Nasional Karimunjawa. Metode yang digunakan adalah metode survei dan teknik pengambilan sampel dengan menggunakan stratified random sampling penerapannya dengan menggunakan line intercept transect. Metode analisis yang dipakai adalah persentase tutupan coral hidup. Penelitian ini menunjukan bahwa keanekaragaman terumbu karang di Taka Tengah sangat tinggi, semua lifeform terumbu karang ditemukan di Taka Tengah. Keanekaragaman lifeform tertinggi ditemukan pada sisi leeward kedalaman 10 m dengan jumlah lifeform 12, sedangkan jumlah lifeform terendah ditemukan pada sisi leeward kedalaman 3 m dengan jumlah lifeform 10. Pemutihan terumbu karang ditemukan pada Acropora Branching dan Acropora Digitate pada kedalaman 3 m pada daerah leeward. Tutupan terumbu karang terbesar ditemukan pada sisi leeward kedalaman 3 m yang memiliki rerata 73,72%, dibandingkan dengan yang terendah pada sisi leeward 10 m yang hanya memiliki rerata tutupan karang hidup 43,13%.
 
The study entitled "Diversity of Coral Reefs Lifeform and Their Responses to Bleaching in Tengah Patch Reef of Karimunjawa National Marine Park" has been completed. It aimed to determine the diversity of coral reefs based on their lifeform, to determine the coral reefs responses to bleaching based on their lifeform, and to determine the condition of coral reefs by measuring their percent cover of living coral in Tengah Patch Reef of Karimunjawa National Marine Park. The method used in this study was a survey and the line intercept transect were placed according to the stratified random sampling techniques. The data obtained presented as percent cover of living coral. This study shows the diversity of coral reefs in the Tengah Patch Reef is very high, all coral lifeforms were found in the Tengah Patch Reef. The highest diversity of lifeform was found in the Leeward side at 10 m depth with a number of 12 lifeforms, while the lowest lifeform was found in the Leeward side at the 3 m depth limited to only 10 lifeforms. Bleaching of coral reefs were found in Acropora branching and Acropora digitate at the 3 m depth in the leeward area. The largest living coral coverage were found in the leeward side at 3 m depth estimated around 73.72%, compared to the lowest coverage in the leeward side at 10 m depth not more than 43.13%.
