Abstract. Hilmi E, Sari LK, Cahyo TN, Muslih, Mahdiana A, Samudra SR. 2021. The affinity of mangrove species using Association and Cluster Index in North Coast of Jakarta and Segara Anakan of Cilacap, Indonesia. Biodiversitas 22: 2907-2920. The affinity of mangrove species using association and cluster index describe relationship among mangrove species. The species association and clustering explain the degree of utilization of resources and space by mangrove species. The association and cluster also describe specific species adaptation in mangrove ecosystems. This paper was aimed to analyze species affinity using association and clustering index of mangrove species. The association index used Chi-square equation and the clustered index used Euclidian distance analysis. The results showed that (i) mangrove density in Segara Anakan (166-4000 trees ha-1) > North Jakarta (220-1100 trees ha-1). (ii) Nypa fruticans, Avicennia marina, Rhizophora stylosa and Rhizophora apiculata dominated in Segara Anakan of Cilacap, and Rhizophora stylosa and Avicennia marina dominated in North Jakarta (iii) The association index had 12 pairs of negative species association and 17 pairs of positive species association, but most of mangrove vegetations had no association. (iv) mangrove ecosystem in Segara Anakan and North Jakarta had four clusters with Euclidean distance (ED score) 484 to describe cluster between Bruguiera parviflora-Bruguiera sexangula until 76430847 to describe cluster among Bruguiera gymnorrhiza, Bruguiera parviflora, Ceriops decandra, Exoecaria agallocha, Nypa fruticans, Ceriops tagal, Rhizophora stylosa, and Sonneratia caseolaris

Abstract. Hilmi E, Hendrayana, Samudra SR, Fikriyya N, Junaidi T, Cahyo TN, Putri NA, Ummah AN. 2024. Species-specific and landscape carbon storage analysis of mangrove forest in Segara Anakan Lagoon, Cilacap, Central Java, Indonesia. Biodiversitas 25: 2748-2755. Mangrove forests are one of the world's largest carbon pools. However, each mangrove species has a different capacity to sequester and store carbon in its biomass. Therefore, at the landscape scale, there are also differences in carbon storage and percent carbon between habitat sites influenced by dominant species and stand density due to differences in environmental conditions. This study aims to analyze each mangrove species' percent carbon and carbon storage and develop a mangrove landscape in Segara Anakan Lagoon, Cilacap District, Central Java Province, Indonesia. This study used destructive methods to collect mangrove samples. The percentage of carbon of each species was analyzed using a formulation of volatile and ash values, while carbon stock for each species was estimated using allometric equations. Landscape analysis of carbon stocks was based on mangrove stand density. The results showed that the carbon percentage of mangrove species averaged between 42.48-53.34% with Rhizophora spp. (R. apiculata, R. mucronata and R. stylosa) and Bruguiera gymnorrhiza having the highest carbon percentage of 47.1-55.6%, followed by Sonneratia spp. and Avicennia with 43.0-48.6%, Ceriops spp., Aegiceras spp., Heritiera littoralis and Xylocarpus spp. with 43.0-48.2%, and Nypa fruticans had the lowest carbon percentage with 39.1-41.0%. At the landscape scale, Segara Anakan had mangrove biomass between 34.83-786.61 tons/ha with carbon stock between 7.85-186.09 tons C/ha. Based on percent carbon, the mangrove landscape in Segara Anakan was dominated by B. gymnorrhiza, R. apiculata, R. stylosa, Ceriops tagal, and R. mucronata. Avicennia marina, Aegiceras corniculatum, N. fruticans, R. apiculata, and Sonneratia alba dominated mangrove landscapes based on carbon storage. The results of this study indicate that carbon storage in mangrove ecosystems is important to support carbon conservation because it has a high percentage of carbon and large carbon storage.
