Mangrove is an ecosystem that has a wealth of macrofauna, which includes plant species and biota associated therein, gastropods and bivalves associated with mangroves as living habitat, shelter, spawning and food supply. The purpose of this study was to determine the diversity of macrofauna associated with mangrove species. This research is a quantitative descriptive research with a survey method. The results showed that the diversity of gastropods and bivalves on the gastropod Cemara beach was 2.05. Bivalvia 1.22. Meanwhile in Bagek Kembar. Gastropods 1.73 and bivalvia 1.32 have relatively low diversity. The results of the analysis using the contingency table at the study site were 8 pairs from the Gastropod class and 4 pairs from the Bivalvia class, these pairs tended to associate at the 5% test level. The macrofauna and mangrove species pairs obtained had a positive association of 6 pairs, namely (Telescopium -Avicennia lanata, Terebralia sulcata -Avicennia lanata, Cerithideacingulata-Rhizophora mucronata, Cerithidea cingulata-Avicennia marina, Cerithideacingulata-Sonneratia caseolaris, Batillaria zonalis -Rhizophora stylosa) whereas in class bivalves there are 4 pairs (Anadara antiquata -Avicennia lanata, Anadara antiquata -Ceriops decandra, Gafrarium pectinatum -Avicennia lanata, Lutraria lutraria-Rhizophora mucronata). This pair of macrofauna with mangrove species shows a close relationship between the two. For future mangrove planting, it can be used as a benchmark by looking at macrofauna and mangrove pairs that are positively associated.

“…Ekosistem hutan mangrove mempunyai kegunaan yang beragam sehingga mempunyai nilai ekonomis yang sangat tinggi (Adinegoro et al 2022). Ekosistem ini juga mempunyai produktivitas biomassa yang tinggi, bahkan dapat mencapai 5.000 grCal/m2 /tahun (Yonvitner et al 2019). Kegunaan hutan mangrove antara lain merupakan spawning ground, nursery ground dan feeding ground bagi berbagai jenis satwa air maupun satwa darat (Adinegoro et al 2022).…”

Coastal and marine areas hold great wealth for the welfare of coastal and small island communities with dynamic magnitudes. Panggang Island and Semak Daun Island have the potential for promising coastal and marine resource assets and provide benefits for community welfare. The research aims to compile a balance sheet of coastal and marine resource assets for Panggang Island and Semak Daun Island. The research was conducted in the Seribu Islands Administrative District, DKI Jakarta Province, in August-September 2023. It included various information data to map the value of ecosystem services and asset balances. The economic valuation method using the benefits transfer technique is used as input for the value of natural resource assets and the coastal and marine environment. The research results show that the value of coastal and marine resource assets of Panggang Island and Semak Daun Island have quite significant dynamics. In 2014-2019, the coastal and marine resource assets of Panggang Island and Semak Daun Island experienced a considerable decline, namely 1,001.92 billion ( Panggang Island ) and 59.97 billion ( Semak Daun Island ). They decreased respectively by 200.38 billion per year (12.34%) and decreased by 11.99 billion/year (9.29%). The estimation results show that there will be an improvement in asset value in 2022 for Panggang Island to 687.73 billion and for Semak Daun Island to 82.32 billion. The estimation results show that there has been an improvement in the ecosystem during the 2020-2022 period. This increase is due to reduced pressure on coastal and marine ecosystems on the two islands. Ecosystem-based integrated management needs to be carried out so that the sustainability and value of resource assets can benefit the welfare of coastal and small island communities.

“…Jumlah jenis biota asosiasi di wilayah kajian menunjukkan kondisi yang kurang baik dimana hal ini dipengaruhi oleh kondisi potensi mangrove. Kemampuan mangrove untuk tumbuh cenderung lebih cepat dibandingkan pertumbuhan biota asosiasi sehingga perlindungan mangrove penting untuk dilakukan agar fungsi pelindung dan penyangga tetap terjaga (Yonvitner et al 2019).…”

Ekosistem mangrove sebagai salah satu ekosistem penting di wilayah pesisir memiliki peran yang sangat besar mulai dari sebagai penyeimbang ekosistem pesisir, penyerap karbon terbesar, sumber unsur hara, area siklus hidup komunitas perikanan hingga sebagai tempat wisata. Peran serta fungsi ekosistem mangrove yang sangat penting ini menuntut kita untuk memiliki suatu bentuk pengelolaan agar tercipta kondisi ekosistem mangrove yang lestari dan berkelanjutan. Salah satu bentuk pengelolaan ekosistem mangrove adalah pengelolaan berbasis kawasan konservasi. Konservasi dapat menjadi suatu alat pengelolaan melalui suatu bentuk pengalokasian wilayah sesuai dengan peran dan kondisi ekosistem, baik di area kawasan yang dilindungi maupun area penyangga. Ketepatan pada pengalokasian pada zonasi kawasan konservasi menjadi penting agar terjadi harmonisasi serta penyelarasan berbagai kondisi ekologi ekonomi dan sosial. Tujuan dari penelitian ini adalah mengidentifikasi kesesuaian ekosistem mangrove di wilayah penyangga TPK Kendawangan sebagai kawasan konservasi perairan untuk pengalokasian wilayah yang dilindungi secara tepat dan berkelanjutan. Pulau Cempedak, Pulau Bawal dan Selat Bilik sebagai wilayah penyangga menunjukkan status kesesuaian yang berbeda. Pulau Cempedak dan Pulau Bawal menunjukkan kondisi tidak sesuai dengan Selat Bilik menunjukkan kondisi sesuai untuk dijadikan kawasan konservasi ekosistem mangrove. Hal ini menunjukkan bahwa batas alokasi yang tidak dijadikan kawasan konservasi ditetapkan pada wilayah perairan kendawangan sudah tepat.
