Coral reefs are ecosystems that are commonly found on small islands in the tropics including the Seribu Islands. The Seribu Islands are a group of 110 islands located off the coast of Jakarta and up to 80 kilometers north of the Java Sea. In this study, we examined the species distribution and diversity of reef fish species on two different distance location in Jakarta Bay using environmental DNA (eDNA) metabarcoding analysis from two sites which are Untung Jawa Island and Harapan Island. The 4L eDNA seawater samples were collected at a depth of 8-9 meters at each site and then analysis using specific primer (MiFish U) of 12S rRNA. Overall, the higher species richness was found on Harapan Island (52 species) followed by Untung Jawa Island (11 species). The Shannon-Wiener Index also showed Harapan Island has higher reef fish diversity based on three taxonomic level (family, genus, and species). There were only five mutual reef fish species found in the two locations, namely Atherinomorus aetholepis, Auxis thazard, Cephalopholis sexmaculata, Epinephelus chlorostigma, and Plectropomus areolatus. The results of these findings in this current study are in line with anthropogenic pressure different where Untung Jawa Island is the closer one to Jakarta Bay than the Harapan Island that located relatively far from Jakarta Bay.","PeriodicalId":42469,"journal":{"name":"Jurnal Ilmu dan Teknologi Kelautan Tropis","volume":"92 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74208121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metode analisis yang digunakan adalah studi literatur, pengujian indikator dari penelitian sebelumnya, depth interview, dan analisis data kuantitatif dan kualitatif. Hasil penelitian ini menunjukkan konversi lahan ekosistem mangrove secara masif telah terjadi sejak tahun 1972-1993 yang berimplikasi pada penurunan luas mangrove yang mencapai 1.166,61 ha. Sedangkan dari tahun 1993-2013, luas tutupan hutan mangrove yang hilang akibat alih fungsi lahan mangrove menjadi tambak mencapai 32,25% dalam kurun waktu 20 tahun.

Area penelitian dibagi menjadi tiga zona dengan total 30 titik pengambilan sampel dengan distribusi yang proporsional. Pada setiap titik dilakukan pengambilan data struktur komunitas semai, tegakan dewasa (pohon, pancang) dan parameter lingkungan. Hasil penelitian menunjukkan status regenerasi mangrove di kawasan ini termasuk dalam kategori cukup baik, berdasarkan perbandingan dari kelimpahan semaian dengan tegakan kategori pancang dan pohon. Kerapatan semai tertinggi ditemukan pada zona 2 yang didominasi oleh Rhizophora mucronata dengan rata-rata sebesar 4800 ± 5610 tegakan/ha yang berbeda signifikan dengan dua zona lainnya. Variasi kondisi struktur komunitas mangrove pada tiga zona tidak memberikan pengaruh yang signifikan terhadap kelimpahan semai. Sementara itu, dua faktor lingkungan yaitu pH dan potensial redoks memiliki korelasi yang positif dan signifikan memengaruhi jumlah sebaran semai mangrove di dalam kawasan.

The rapid Appraisal for Land Use (Raplanduse) method was used to assess the sustainability and sensitivity of the attributes used in this study. The formulation of management strategies was carried out based on the levels of influence and dependence on sensitive attributes analyzed by the prospective analysis method. The results showed that the sustainable use of small islands in the Tiworo Islands varied, ranging from good, bad to less sustainable. Sensitive attributes observed in the ecological dimension were suspended solid materials and seawater surface temperature. In the social dimension, the sensitive attributes assessed were the conflict incidence among residents and human resources. Attributes observed in the economic dimension were income level, availability of business capital, and fisheries catch production. In the legal and institutional dimensions, the sensitive attributes observed were land ownership status and area zoning. Strategic management was developed based on these sensitive attributes, including increasing community adaptation capacity, controlling land-use in watershed areas in the mainland, developing business diversification, regulating spatial utilization, and improving the quality of human resources.","PeriodicalId":42469,"journal":{"name":"Jurnal Ilmu dan Teknologi Kelautan Tropis","volume":"64 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86187131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
