| dc.description.abstract | Sea grass bed is an important ecosystem in coastal areas and small island which plays important and effective roles as a protector of the coastal line and the safety of the mainland area of small islands. Physically, the roles of ecosystem were as erosion prevention, sediment trap and barrier of waves and currents. The existence of these ecosystems in the coastal regions and small island was an important in enhancing the adaptive capacity of islands against natural disaster because the island serves as a natural protector. The aim of this research was to calculate and assess the adaptive capacity of sea grass ecosystem growing in the waters of around the small island the small island in the group of Guraici. The research was conducted on 17 island located in the group of Guraici island. Measurement of adaptive capacity of sea of sea grass ecosystem was done by analyzing 6 parameters, namely: Sea Grass Dimension Index (IDLn), Dominat Speciest of Sea Grass, Sea Grass Coverage Percentage (%), Number of Sea Grass Species of Sea Grass, Sea Point of Ecosystem. Sea Grass ecosystem adaptive capacity of five categories of “very low, low, medium, high and very high”. These Results indicated that sea grass ecosystem growing in the waters of around the islands in the island of group Guraici had adaptive capacity with values ranging between 0.0-0.59. The ranges of values were distributed into three categories of the adaptive capacities (very low, low and medium). A total of 13 islands had a capacity of sea grass ecosystem “medium”, the other three islands with capacity of “low” and one island with a capacity of “very low”. | en |
