摘要：This study aims to analyze the structure and composition of mangrove vegetation in Pantai Bakti and Pantai Bahagia villages, Bekasi Regency, in West Java, to provide primary data related to mangrove forest diversity. This study was conducted in the surrounding area of Mangrove Restoration Program in the North Coast of Java “REMAJA” conducted by PHE ONWJ in Pantai Bakti and Pantai Bahagia villages (Muara Beting and Muara Bendera), Bekasi Regency, West Java in November 2021. Data analysis was conducted to determine the condition and composition of mangrove species at the research site using a transect plot. The analyses include important value index (IVI), species density (K), ShannonWiener diversity index (H'), dominance index (C), and evenness index (E). Generally, the results showed that Pantai Bahagia has a high density for all types of growth compared to Pantai Bakti village. Particularly in Muara Beting sample plots which have 16.250 ind ha-1 at seedling level. In Pantai Bakti, no species were found at seedling level in the sample plots. Moreover, Pantai Bakti has higher IVI than Pantai Bahagia sample plots. The index results mainly show that mangrove in Pantai Bakti has very low diversity and moderate evenness. While in Muara Beting has low diversity and low to moderate evenness. Muara Bendera has low to moderate diversity and moderate to high evenness index. Comparing the wide areal extent of mangrove covers in Bekasi Regency, it can be improved to moderate to high composition of mangrove by a massive mangrove planting program.
