ABSTRACT
The Coastal Bandengan was one of habitat for seagrass. Density seagrass lived could redocing wave energy, so that caould precipitate particles and organic nutrients into the food source of the biota infauna. Research conducted in March 2016 at the Coastal Bandengan this experiment knowed the relationship of the content of organic of sediment matter with infauna abundance on the density of different at Coastal seagrass Bandengan Jepara. The method used Purposive Random Sampling methods i.e., the sampling technique when a sample taken has certain considerations. The results showed 1 type of seagrass found at Coastal Bandengan i.e. Thalassia sp with the density of each station 1840 ind/5m2, 1200 ind/5m2, 890 ind/5m2. Organic matter of sediment in solid density, medium rare and successive – co-designer were 9.81%, 8.00%, 5.71%. The abundance of infauna in the dense seagrass density, medium rare in the coastal Bandengan 26315 ind/m3, 22262 ind/m3 18304/m3. The results of the regression test obtained the equations y = 984.52 x-288.5, that relations are positive, meaning that increased the density of the seagrass were following by the increasing organic matter, but didn’t follow by an abundance of infauna. The value of R² = 0.164206, and the value of r = 0.405224, that the relationship of the content of organic materials with the abundance of infauna had medium, because the value of the correlation of 40.52%.
