ABSTRACT
Seagrass ecosystem in Bandengan coastal Jepara is important for epifauna. Different seagrass density will affect levels of organic matter used epifauna, in addition the density of seagrass can also precipitate organic particles which affect the abundance of epifauna. This research was conducted on March 2016. The aimed of this research was to determine the relationship of epifauna’s abundance to density seagrass and the relationship of organic matter to the density of seagrass. This research used survey method and random sampling technique. Samples were taken from three different station there are (A) sparse density, and (B) dense density. Sample epifauna were taken once a week for three time. The results showed only 1 type of seagrass found in Bandengan coastal Jepara that is Thalassia sp. With density on sparse station (A) 178ind/m2, dense station 368 ind/m2. The abundance of epifauna on station sparse (A) 140 ind/3m2, dense station (B) 91 ind/3m2, The highest abundance Sconsia sp 52 ind/m2 dan 28 ind/m2 and Cerithium sp 34 ind/m2 dan 19 ind/m2Organic material content of sedimen on density was sparse and dense was 5.71%, 9.81%. Based on the result of the correlation show that between the abundance of epifauna with seagrass density level there is a relation undirectional, density of seagrass will not increase accordingly to the abundance of epifauna, as well as to the content of organic matter. There is a close correlation that higher of density of seagrass will be followed by organic matter.
