“…As a comparison, the coral reef in the north part of Panggang Island had a live coral cover of 27.2% (Prasetyo et al, 2018). Pramuka Island had a live coral cover of 72.38% (Permana et al, 2020). Kelapa Island had a live coral cover of 55.83% (Mutahari et al, 2019).…”

Coral reefs are critical ecosystems for coastal and marine biota interaction. The coral reef ecosystem on Kelapa Dua, Seribu Islands, is in poor condition with a low live coral cover. This condition decreases fishery productivity, as the coral reef is the habitat and nursery ground for fish and marine biota. The problem in this research is how to increase the percentage of live coral cover on Kelapa Dua Island, so fishermen do not have to fish further to other islands. This study aims to analyze the coral cover percentage and the economic value of the direct use value of capture fisheries services from the coral reef ecosystem on Kelapa Dua Island. The method used in this study to calculate the percentage of coral reef cover is Underwater Photo Transect (UPT) at a depth of 5 meters along 50m at three locations. The method for the capture fisheries data collection is an accidental sampling questionnaire to 30 out of 50 fishermen with a market value approach. The results of this study indicate that the economic valuation of coral capture fisheries services on Kelapa Dua Island per year for fishermen is IDR 394,800,000/US$ 25,165 (1 USD=15,688 IDR) with a coral reef coverage percentage of 12.45%. This value contributes 2.5% of the economic value of capture fisheries services of the coral reef ecosystem in the entire Kepulauan Seribu National Park. This value can be increased by increasing the diversity of types of catch, the biomass of the catch, and the selling price of the catch.

“…Both are important in contributing to fisheries, as indicated by the presence of chlorophyll-a and phytoplankton in their waters [24]. Although on Pramuka Island, most people work as fishermen, on the other hand, the tourism sector, with the attractiveness of coral reefs, is an important aspect of the Pramuka Island community [25]. The present study revealed that the physicochemical parameters of various sampling sites in Pramuka Island showed conditions that were not significantly different for physical factors but had differences in their nautical content, namely nitrogen.…”

The connectivity between seagrass and mangrove ecosystems has synergistic benefits of conserving the land-sea ecosystems of the small islands. The physicochemical properties of the two ecosystems lead to the success of the habitat of the interconnected zone. This study aimed to analyze the physicochemical factors in the mangrove and seagrass ecosystems on Pramuka Island and understand the factors influencing the phytoplankton production of small island coastal ecosystems. Sediment and water collection were carried out on Pramuka Island, Indonesia, to measure physicochemical parameters. Mangrove and seagrass ecosystems have the highest DO, temperature, and pH values. The phytoplankton counts showed significant variation between the sampling sites with a predominance of the class Cyanophyceae. The estimated primary productivity of chlorophyll-a indicated that its concentration was higher in mangroves than in seagrass. A similar trend was observed in nutrient loads and dissolved inorganic nitrogen. Results of the present study clearly showed that an increased concentration of dissolved inorganic nutrient influence the concentration of chlorophyll-a as an indicator of primary productivity. These findings will provide a preliminary analysis of the physicochemical conditions and productivity on Pramuka Island.

“…Jika suatu ekosistem terumbu karang sehat, maka semakin beragam dan kaya biota yang hidup di ekosistem tersebut (Cappenberg & Akbar, 2020). Berbagai survei menunjukan bahwa tutupan karang hidup rata-rata menurun secara berkala dikarenakan gangguan maupun ancaman lebih cepat mempengaruhi dibandingkan dari tingkat pemulihannya (Permana et al, 2020). Namun demikian, upaya rehabilitasi dan meningkatnya kesadaran masyarakat terhadap pentingnya ekosistem terumbu karang menjadi optimisme dalam peningkatan kondisi terumbu karang baik secara kualitas maupun kuantitas.…”

Biota yang berasosiasi dengan ekosistem terumbu karang cukup banyak, beberapa diantaranya yaitu ikan karang dan megabentos. Riset ini bertujuan untuk mengetahui kondisi tutupan terumbu karang dan bagaimana hubungannya dengan distribusi ikan karang, megabentos serta kualitas perairan di Perairan Gosong Pramuka Kepulauan Seribu. Pengambilan data ikan karang menggunakan metode UVC, megabentos menggunakan metode Belt Transek dan pengambilan data terumbu karang menggunakan metode LIT. Data diambil pada 2 stasiun yang berlokasi pada wilayah terumbu karang alami dan wilayah yang terdapat media transplantasi karang dengan tiga kedalaman yaitu 3 m, 5 m, dan 7 m. Tutupan terumbu karang di Perairan Gosong Pramuka tergolong kriteria sedang. Kelimpahan ikan karang dan megabentos di kedalaman 3 m lebih tinggi daripada kedalaman lainnya dan memiliki nilai indeks keanekaragaman sedang. Hubungan ikan karang dengan terumbu karang pada riset ini menunjukan hubungan positif namun bernilai rendah yang artinya hubungan lemah, sedangkan hubungan megabentos dengan kualitas perairan di Gosong Pramuka memiliki nilai yang bervariasi yaitu terdapat hubungan positif kuat dan juga lemah. Abundance, Diversity and Distribution of Coral Fish and Megabentos and their relationship to the condition of coral reefs and the quality of waters in Gosong Pramuka, Thousand Islands National Park There are quite a lot of biota associated with coral reef ecosystems, some of which are coral fish and megabentos. This research aims to determine coral reef cover conditions, determine the distribution index of coral fish and megabentos and obtain a relationship between coral fish and coral reef conditions and megabentos with water quality in the Gosong Pramuka Waters of the Thousand Islands. Pengambilan data coral fish using UVC method, megabentos using Belt Transek method and coral reef data retrieval using LIT method. The data were taken at 2 stations located in natural coral reef areas and areas where there is a transplane media with three depths, namely 3 m, 5 m, and 7 m. Coral reef cover in Gosong Pramuka Waters is classified as a medium criterion. The abundance of reef fish and megabentos at a depth of 3 m is higher than other depths and has a moderate diversity index value. The relationship between coral fish and coral reefs in this study shows a positive but low-value relationship, which means a weak relationship, while the relationship between megabentos and the quality of waters in Gosong Pramuka has a varied value, namely there is a strong and also weak positive relationship.
