This research was conducted in the mangrove forest of Popongan beach at Baluran National
Park, East Java. The aim of this research was to determine the relationship between
mangrove density and Portunidae diversity in mangrove forest at Popongan beach. Line
transect method was used in this research. There are three tr ansects consist of 17 plots, each
plot sized 20m x 20m. The data analysis were done by using Person correlation and linear
regression R Program. The results showed p-value 0,003, it means there is relationship
between Portunidae diversity and the mangrove density. The temperature and tide showed
p-value < 0,005, that means the abiotic factors affect Portunidae diversity in mangrove. The
Portunidae diversit y at mangrove forest of Popongan beach is relativel y low (H’value 0, 152).
There were five species was found, there were Charybdis (Charybdis) miles, Podhopthalmus vigil,
Portunus pelagicus, Scylla serrata, and Thalamita crenata. The dominant species in this mangrove forest is
Thalamita crenata. The composition of mangrove forest vegetation were Rhizophora apiculata, Ceriops tagal,
Lumnitzera racemosa, Rhizophora stylosa, Sonneratia alba, Bruguiera gymnorrhiza, Pemphis acidula, dan
