Kawasan konservasi perairan pesisir Morowali merupakan kawasan konservasi yang memiliki hamparan terumbu karang yang begitu luas. Kawasan konservasi dapat berjalan secara optimal apabila dikelola yang efektif berdasarkan pemantauan kondisi ekosistem pesisir dan laut yang dilakukan secara berkala. Upaya yang dapat dilakukan untuk menjaga potensi sumberdaya di kawasan konservasi adalah dengan penyediaan informasi awal mengenai kondisi biofisik terumbu karang di dalamnya termasuk ikan. Tujuan dari penelitian ini untuk mendapatkan data awal mengenai ekosistem terumbu karang; ikan; luasan area tutupan terumbu karang; serta mengetahui indeks keanekaragaman, dominansi, dan keseragaman karang di Perairan Morowali. Metode survei pada penilaian kondisi dan komposisi tutupan terumbu karang menggunakan metode (Underwater Photo Transect = UPT). Pengambilan data ikan dilakukan dengan (Fish Visual Cencus). Pengamatan ikan dilakukan dengan transek pengamatan seluas 5 x 25 meter persegi. Berdasarkan hasil penelitian bahwa persentase karang hidup di Kawasan Konservasi perairan Morowali adalah 23,27% berarti terumbu karang berada dalam kategori rusak. Terumbu karang di kawasan konservasi perairan Morowali memiliki 36 genus dari 15 Famili yang didominasi oleh karang dari Genus Porites (278 individu), Fungia (132 individu), Montipora (108 individu) dan Acropora (94 individu). Hasil pemantauan ikan karang menunjukkan 56 jenis ikan karang berasal dari 18 famili dan 38 genus dengan kelimpahan individu 1.032 individu/m2. Tingginya kerusakan terumbu karang akibat aktivitas manusia dapat diminimalisir melalui pengawasan (monitoring dan surveilance) yang ketat.
The Banggai KKPD is located in the coastal area and small islands of Banggai Regency, Banggai Archipelago and Banggai Laut which has the potential for coral reef biodiversity with a fairly wide expanse of coral reefs along the coast and small islands. The core zone area in the Banggai Conservation Area is 42,879.58 ha or 5.01%. The aim of this research is to provide initial data (T0) related to the health condition of coral reef ecosystems in the core zone of the Banggai Water Conservation Area. This research was carried out for 2 months, namely in October -November 2019, with a total of 10 observations. Coral cover data was collected using the UPT (Underwater Photo Transect) method. The condition of corals in the core zone of the Banggai KKPD varies greatly, ranging from damaged, moderate, to found corals in very good condition. The results of the analysis of coral reefs in the core zone in the Banggai KKPD area have an average percentage value of 29.93% so that the condition of the corals at 10 points is in the "MEDIUM" category. The base substrate cover in Banggai MPA apart from live hard corals was also dominated by dead corals (38.35%) and abiotic components (16.80%) such as sand and coral fractures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
