Abstract

The coastal area of Pasarbanggi, Rembang Regency is a mangrove estuary with dynamic sedimentation and ecological processes. This study was conducted to examine the sedimentation and salinity changes using diatoms contained in 50 cm sediment cores. The core divided in 5 cm intervals and processed with digestion, identification and enumeration to determine the changes of diatom habitat zone. The result are: Zone 1 (0-15 cm) dominated by brackish diatom identified in the clay and sand layers intercalation, indicating the influence by tides; Zone 2 (15-50 cm) dominated by freshwater diatoms contained in the thick clay and sand layers with a small amount of organic matter, indicating the influence of freshwater. Therefore, it can be seen that the influence of sea water is increasing over time. Thus, sustainable environmental management is needed, one of which is the preservation of mangrove forests in the coastal area.
