ABSTRACT
The research is located in the Bungus Bay Waters Padang. The purpose of this study was to analyze the grain size and rate sedimentation of Coral Reefs and Seagrass. Bungus Bay Waters, including in the area of the Bungus District administration TelukKabung, located in the Southern part of the Padang City. The method used to analyze the grain size of sediment that is based on the scale of classification Wentworth- Udden, which sampling using the tool Sediment Grab, while the rate of sedimentation is done by using a Sediment Trap, in the form of Acrylic Tubes that is attached to the bottom waters and a Coral Reefs monitoring was conducted by LIT (Line Intercept Transect) and observations of Seagrass Ecosystems using transect method quadratic size of 1 x 1 m. The results showed high sedimentation in the Bungus Bay Waters with sedimentation rate with an average 400.58 - 1456.76 mg/cm2/day. This is significant impact on the growth of Coral Reefs and Seagrass. With the measurement results of the sedimentation rate in three streams indicating fairly high sedimentation in the Bungus Bay Waters. This incident could cover coral reefs ecosystem and seagrass in the area, but not so affect to the Mangrove Ecosystems. Thus in generally the sedimentation can damage the ecosystem in the Bungus Gulf Region.
