The Effect On Mangrove Density With Sediment Rate in Coastal Pasar Banggi Of Rembang Regency

Abstract

The existence of mangrove ecosystems in coastal Pasar Banggi serves to protect the shoreline and wildlife habitat as fishing for spawning, nursery, and feeding ground. In addition, mangrove ecosystems can also grab sediments through the root system forming new land. The formation of the new land can eventually be utilized for mangrove growth media either naturally or through the planting activities to support the sustainability of mangrove ecosystems. The method used is vegetation analysis and sediment trap. The results showed that the dominant mangrove species in Coastal Pasar Banggi Rembang were Rhizopora apiculata. The results showed the average value of the highest sedimentation rate at station A 291,479 gr/cm2/day with the lowest average mangrove density of 57822 ind/ha. The lowest average sedimentation rate at station B was 171,095 gr/cm2/day with the highest average mangrove density of 105311 ind/ha, mean medium sedimentation rate at station C was 219,461 gr/cm2/ day with average medium mangrove density of 888089 ind/ha. This research is expected to be an information material about the rate of sedimentation which will be expected as a mangrove conservation management. Based on the results of the research, the relationship between mangrove density and sedimentation rate resulted in negative correlation (-1) meaning that the lower of mangrove density, the higher the sedimentation rate and the higher the mangrove density, the lower the sedimentation rate
