Abstract

Coral reefs are vital ecosystems facing serious threats due to climate change and human activities. This research aims to evaluate the condition of live coral cover in the Sawo-Lahewa Aquatic Tourism Park (TWP) Regional Marine Conservation Area (KKPD), North Nias Regency, as an important step in conservation and sustainable management efforts. Data was collected at 8 research stations using the Underwater Photo Transect (UPT) method. The research results show that the condition of coral reefs in this area is in the damaged to moderate category, with the percentage of live coral cover ranging between 12.33-45.37% and an average of 26.65%. The highest percentage of coral cover was found on Sarangbaung Island (45.37%) in the medium category, followed by Makora Island (42.13%), Gita Island (35.35%), and Lafau Island (31.07%). Meanwhile, locations with the lowest cover in the damaged category include Gosobaohi_01 Island (18.25%), Gosobaohi_02 Island (15.60%), Sifahandro Sea Waters (13.13%), and Bengkuang Bay Waters (12.33%). This research also looks at the abundance of coral juveniles, coral fish, and megabenthos to provide a broad picture of the health of the coral reef ecosystem. The results of this research can become a scientific basis for developing more effective management strategies. Apart from that, it is also a form of supporting conservation efforts, helping restore damaged ecosystems, and increasing the resilience of coral reefs to future environmental threats.Keywords:  Coral Reefs, Regional Marine Conservation Area, North Nias

Abstract

Pulau Pini dan pulau-pulau kecil di sekitarnya merupakan wilayah pesisir yang memiliki ekosistem penting, seperti terumbu karang, padang lamun, dan mangrove yang berperan sebagai habitat utama berbagai sumber daya ikan dan penopang keanekaragaman hayati laut. Namun demikian, informasi ilmiah mengenai kondisi ekosistem serta tantangan pengelolaan kawasan konservasi di wilayah pulau-pulau kecil ini masih relatif terbatas. Penelitian ini bertujuan untuk menganalisis potensi ekologi, tantangan, serta arah pengelolaan kawasan konservasi di perairan Pulau Pini, Kecamatan Pulau-Pulau Batu Timur, Kabupaten Nias Selatan, Provinsi Sumatera Utara. Pengumpulan data dilakukan pada bulan November 2023 di Kawasan Konservasi Perairan Daerah (KKPD) Pulau Pini melalui pengamatan kondisi ekosistem mangrove, lamun, dan terumbu karang. Analisis data dilakukan secara deskriptif untuk menilai status ekosistem pesisir, sedangkan identifikasi faktor internal dan eksternal pengelolaan kawasan konservasi dianalisis menggunakan pendekatan SWOT (Strengths, Weaknesses, Opportunities, and Threats). Hasil penelitian menunjukkan bahwa kawasan ini memiliki potensi ekosistem pesisir yang signifikan dengan ditemukannya 7 spesies mangrove dan 6 spesies lamun. Persentase tutupan lamun berkisar antara 32,75%–61,50% yang menunjukkan kondisi ekosistem dari kategori kurang sehat hingga sehat. Kondisi terumbu karang tergolong kategori kurang dengan rata-rata tutupan karang hidup sebesar 38,35%, sedangkan mangrove berada pada kategori sedang dengan sebaran yang relatif terbatas. Zonasi kawasan konservasi terdiri atas zona inti, zona pemanfaatan terbatas, dan zona lain sesuai peruntukannya yang diarahkan untuk perlindungan ekosistem pesisir. Hasil analisis SWOT menunjukkan bahwa pengelolaan kawasan konservasi Pulau Pini berada pada Kuadran I (strategi SO), yang menekankan pemanfaatan kekuatan ekosistem pesisir untuk memaksimalkan peluang pengelolaan kawasan konservasi secara berkelanjutan. Temuan ini menegaskan bahwa penguatan perlindungan habitat, pemantauan ekosistem secara berkala, serta peningkatan partisipasi masyarakat merupakan strategi utama dalam mendukung pengelolaan kawasan konservasi yang berkelanjutan di perairan Pulau Pin
