Abstract

Cengkrong Beach in Trenggalek Regency has extensive mangrove forest. Mangrove forests play an important role in maintaining aquatic productivity and supporting people's lives. Bivalve is one of the biota that lives in mangroves and is used by the people around the mangrove forest. The research aims to identify mangroves and bivalves, analyze the abundance of mangroves and bivalves, and determine the relationship between mangroves and bivalves. Mangrove sampling was carried out on 6 transects. Each transect was made 7 with plots measuring 10 m x 10 m with a distance of 5 m and bivalve samples were taken using a 1 m x 1 m plot with 5 plots in that plot. Research data were analyzed using PAST 4.13. The results of the study found 15 species of mangroves and 4 genera of bivalves. The highest mangrove abundance value was Rhizophora apiculata with a value of 0.0092 indiv./m2 and bivalves were of the genus Isognomon with a value of 4.138 indiv./m2. The results of the analysis showed that there was a relationship between the mangrove Sonneratia caseolaris and the bivalve of genus Pilsbryoconcha, the mangrove Aegiceras floridum and the bivalve of genus Geloina, the mangrove Avicennia alba and the bivalve of genus Saccostrea and the mangrove R. apiculata and the bivalve of genus Isognomon.
