Abstract:
The benefit of this research is to understand macrozoobenthos diversity and its connection to
mangrove density in Pagatan Besar Village. Determination of observation stations by
purposive sampling method. Research on macrozoobenthos was carried out in a 10 m × 10
m mangrove vegetation observation transect. The results showed that the macrozoobenthos
found consisted of 12 species, namely Polymesoda bengalensis, Uca lactea annulipes,
Scylla serrata, Episesarma, Chicoreus capucinus, Cerithidea quoyii, Cassidula aurisfelis,
Telescopium Telescopium, Ellobium aurisjudae, Calliostoma zizyphinum, Nerita lineata and
Littoraria scabra. The macrozoobenthos density index from the three stations produced
various values. The diversity index of the three stations belongs to the moderate diversity
category (H' 1 < H' < 3.322). The uniformity index of Stations 2 and 3 is included in the high
uniformity category (0.6 ≤ E ≤ 1.0) and Station 1 is included in the medium uniformity
category (0.4 ≤ E < 0.6). The dominance index values of the three stations indicate that there
are macrozoobenthos species that dominate at each station because the value of D > 0.5.
The results of a simple correlation analysis of "Pearson Product Moment" between mangrove
density and macrozoobenthos density produce a fairly weak relationship with mangrove
density where the equation shows a negative value (-).
