“…Pulau Karang Congkak termasuk ke dalam zona pemanfaatan (Dit. KKIJ 2015) yang ditujukan untuk permukiman, wisata atau untuk kegiatan budi daya ikan (Riyadi 2007). Pulau lain yang berada di sekitar Pulau Karang Congkak seperti Pulau Panggang merupakan daerah permukiman padat penduduk (Assuyuti et al 2018) dan Pulau Semak Daun sebagai destinasi wisata.…”

Seagrass are globally known as an essential habitat for marine fishes. The study of fish assemblages in seagrass ecosystem is needed as the first base to select the most suitable coastal fisheries management. The study aims to reveal the composition of fish assemblages both seasonally and spatially in Karang Congkak Island, Kepulauan Seribu. Sampling was performed six times in NW monsoon (March), first transitional monsoon (April-May) and SE monsoon (Juni, August, September) 2018. Fish were sampled at four sites at seagrass ecosystem of Karang Congkak Island, namely eastern, southern, western, and northern by using beach seine net. The differences of juvenile fish assemblages were analyzed using One-Way ANOSIM. A total of 6,326 fish were collected belonging to 78 species, 31 families and 10 orders in which Labridae was the most diverse family. The result indicates strong spatial and temporal variation in fish composition. Fish compositions were dominated by juvenile both spatially and temporally. The most common species that inhabits seagrass beds of the Karang Congkak Island as temporary resident such as Gerres oyena and Siganus canaliculatus, and regular visitor namely Halichoeres argus. Cannonical correspondence analysis indicated strong correlation between several fish species and environmental variables.

“…KCI is reported as an island with shallow water of dead corals surrounded by a barrier reef. Surrounding these ecosystems are shallow marine components like coral reefs and seagrasses, with substrates primarily composed of sand, sand mixed with seagrasses, and corals 23 . The benthic habitat mapping outcome for KCI is depicted in Figure 7.…”

Seagrass beds are ecosystems that are sensitive to anthropogenic pressures. The restrictions imposed on human activities during the Covid-19 pandemic provide a unique opportunity for coastal ecosystems to recover. This situation presents a chance to monitor seagrass ecosystems on Panggang Island and Karang Congkak Island, aiming to observe any changes in the seagrass area. The method employed to ascertain the community structure involved photo transects, which were then processed using a machine learning supervised classification approach utilizing the random forest algorithm. The classification process categorized the area into five classes: seagrass, macroalgae, coral, bare substrate, and dead coral algae. Confusion Matrix Test was chosen to assess mapping accuracy, setting an accuracy threshold of ≥ 60%. The findings reveal notable alterations in seagrass areas across both islands. Panggang Island exhibited a considerable increase in seagrass coverage by 21,05 hectares. Conversely, Karang Congkak Island experienced a decrease of 2,88 hectares in seagrass coverage. These observed changes are likely not influenced by the anthropause phenomenon but rather by natural occurrences between 2019 and 2022, including the La Niña Triple Dip phenomenon and variations in sampling time during the transition season. The Overall mapping accuracy (OA) results for

“…Menurut Pujianti (2010), profitabilitas akan ditentukan oleh tingkat efisiensi operasional bank tesebut. Namun menurut Riyadi (2006), sukses dan tidaknya suatu perbankan dipengaruhi oleh banyak aspek, diantaranya aspek manajemen, sumber daya manusia, pemasaran, dan kondisi keuangan yang dimilikinya. Kondisi keuangan bank dapat dikatakan baik atau buruk salah satunya dilihat dari rentabilitas yang dimilikinya.…”

Penelitian ini bertujuan untuk menganalisis pengaruh kecukupan modal, risiko kredit, efisiensi, dan likuiditas terhadap profitabilitas perbankan. Variabel independen dalam penelitian ini adalah Capital Adequacy Ratio (CAR) sebagai proksi dari kecukupan modal, Non Performing Loan (NPL) sebagai proksi dari risiko kredit, Beban Operasional terhadap Pendapatan Operasional (BOPO) sebagai proksi dari efisiensi, dan Loan to Deposit Ratio (LDR) sebagai proksi dari likuiditas. Profitabilitas diukur dengan Return On Asset (ROA) sebagai variabel dependen. Sampel yang digunakan dalam penelitian ini adalah Bank Umum Konvensional yang terdaftar di Bursa Efek Indonesia sebanyak 25 Bank selama periode 2016-2021. Pemilihan sampel tersebut menggunakan Purposive Sampling Method dengan kriteria hanya Bank yang memiliki nilai Return on Asset (ROA) yang positif yang dipilih sebagai sampel. Hasil analisis regresi berganda menunjukkan bahwa rasio CAR dan NPL tidak berpengaruh terhadap profitabilitas, rasio BOPO berpengaruh negatif dan signifikan terhadap profitabilitas sedangkan rasio LDR berpengaruh positif terhadap profitabilitas.
