Abstract

Luasan terumbu karang perlahan semakin berkurang akibat faktor alam ataupun manusia. Restorasi terumbu karang harus dilakukan salah satunya dengan transplantasi karang. Caulastrea curvata merupakan salah satu karang hias yang diminati oleh penggiat reef aquarium sehingga seringkali terjadi eksploitasi yang berlebihan terhadap karang ini. Permasalahan ini bisa diatasi dengan solusi alternatif dari budidaya karang, yaitu menggunakan metode fragmentasi. Tujuan dari penelitian ini adalah mengukur total pertumbuhan dari fragmen karang hias jenis Caulastrea curvata yang ditransplantasikan menggunakan metode fragmentasi. Metode yang digunakan dalam penelitian ini adalah metode observasi. Observasi fragmen karang menggunakan Underwater Photography dan diolah menggunakan software ImageJ untuk mendapatkan nilai pertumbuhan tinggi dan area. Hasil dari penelitian ini didapatkan nilai total pertumbuhan luas area dan tinggi berurutan sebesar 5,56 cm2 dengan penambahan 1 cm2 dan 3,38 cm dengan penambahan 0,75 cm selama 5 bulan. Kesimpulannya adalah total pertumbuhan luas area dari karang ini lebih cepat daripada total pertumbuhan tingginya dan penggunaan metode fragmentasi berhasil mempercepat pertumbuhan karang jika dibandingkan dengan metode sexual.

Abstract

Ikan pembersih merupakan spesies ikan yang berinteraksi dengan organisme laut lainnya dengan membersihkan tubuh mereka dari parasit dan sisa-sisa debris. Ikan ini memiliki peran penting dalam menjaga kesehatan berbagai spesies laut, termasuk pari manta karang (Mobula alfredi). Namun, keterbatasan pemahaman mengenai interaksi antara ikan pembersih dan pari manta karang menjadi tantangan dalam upaya konservasi laut. Penelitian ini bertujuan untuk mengidentifikasi spesies ikan pembersih yang berinteraksi dengan pari manta karang (M. alfredi) di Manta Sandy, Selat Dampier, Raja Ampat. Metode yang digunakan dalam penelitian ini adalah modifikasi jebakan kamera (camera trap), dengan menempatkan tiga kamera GoPro pada lokasi yang berbeda di area penelitian. Pengambilan data dilakukan selama 14 hari pada bulan Februari 2023 untuk mendokumentasikan interaksi ikan pembersih dengan pari manta karang. Hasil penelitian menunjukkan bahwa terdapat tiga spesies ikan pembersih yang ditemukan di Stasiun Pembersihan Manta Sandy, yaitu Labroides dimidiatus, Thalassoma lunare, dan Chaetodon kleinii. Penelitian ini mengonfirmasi keberagaman spesies ikan pembersih di Manta Sandy serta memberikan wawasan penting mengenai peran ekologis dan signifikansi konservasi spesies tersebut. Hasil penelitian ini dapat menjadi referensi penting bagi penelitian lebih lanjut dalam rangka mendukung upaya pelestarian keanekaragaman hayati laut di wilayah Raja Ampat dan sekitarnya.

Abstract

Graphical Abstract   Highlight Research Coral colonies affected by coral disease are identified and counted. White syndrome is a type of coral disease that is dominattly found. Coral cover in the Kepulauan Seribu is in moderate condition. A weak correlation between the prevalence of coral disease and live cover in the Kepulauan Seribu     Abstract Kepulauan Seribu is designated as a marine conservation area in Kepulauan Seribu National Park and is one of high tourism development areas on the north side of Jakarta, the capital city of Indonesia. Anthropogenic sources from these nearby areas has reduced the health condition of coral reefs and increased the prevalence of coral diseases in the study area. This study aimed to determine the genus of coral infected by disease, the type of disease, and the relationship between the prevalence of disease and live cover in Kepulauan Seribu. Data was collected using the survey method. Coral cover is assessed using Underwater Photo Transect (UPT) and disease is assessed using Belt Transect methods, respectively. The result showed that 14 genera of coral species were infected and dominated by Porites, Montipora, and Acropora. Furthermore, there were 5 types of diseases, dominated by White Syndrome (WS), Atramentous Necrosis (AtN) and Ulcerative White Spots (S). The correlation analysis results showed a very low relationship between disease prevalence and live coral cover (r = 0.10). This research can be used as input or reference for more sustainable coral reef management, by improving an integrated coastal education system for the younger generation and developing more sustainable tourism activities in the future in Kepulauan Seribu.

Abstract

The increasing anthropogenic activities in Menjangan Kecil Waters can reduce the health condition of coral reefs in these waters. Therefore, it is necessary to investigate the level of bleaching attack that occurs in these waters. The purpose of this study was to determine the health condition of coral reefs in Menjangan Kecil Waters by observing the level of bleaching attack based on coral colour which is related to the density of zooxanthellae in coral living tissue. The CoralWatch method was applied to estimate the level of bleaching attack based on the level of coral colour in the coral health chart table. The results of this study revealed that the condition of coral reefs at 4 stations was dominated by colour levels 3-4, meaning that the condition of coral reefs began to bleach. The increasing of anthropogenic activities causes excessive interaction with coral reefs and human, thus accelerating the potential for bleaching. Optimization of ecotourism in Menjangan Kecil Waters, Karimunjawa needs to be done by conducting further studies on coral reef health.

Abstract

Graphical Abstract   Highlight Research Pocillopora spp. grew faster on coral tree media (0.55 cm/month) than on coral table media (0.15 cm/month). Survival rates were high, with 97.3% on coral trees and 87.0% on coral tables, proving both methods effective. Coral growth on table media was slower due to sediment accumulation, while tree media provided more stable growth. ANOVA analysis showed no significant effect of transplant media on growth and survival, confirming adaptability. Both methods are viable for large-scale coral reef restoration, especially in the Anambas Islands and similar ecosystems.     Abstract Pulau Semut Kecil, Anambas Islands, are located within the coral reef triangle, as one of the largest Marine Protected Areas (MPAs) in Indonesia. Coral reefs possess significant functional attributes within ecosystems, and their condition is progressively deteriorating due to anthropogenic activities. This situation necessitates restoration endeavors, primarily through coral transplantation methodologies. The methods involved the introduction or relocation of donor corals into substrates such as tree transplantation media and tables, exhibiting high success rates. This study was conducted to determine the growth and survival rate of Pocillopora spp. The direct survey approach was used and the different coral transplanting media were statistically analyzed with the ANOVA test and SPSS software. The results of the growth of coral fragments Pocillopora spp. Reported coral tree media and table with an average value of 0.55 cm/month and 0.15 cm/month. The survival rate of Pocillopora spp. coral fragments in tree media and table was 97.3% and 87.0%. The media for dropping coral trees and table did not affect the growth and survival rate. This coral transplantation method can facilitate for the restoration of degraded ecosystem and ecological succession.
