【 摘 要 】

Unggeh Island is one area that has the potential of Sea Cucumber in the North Sumatra. Sea cucumbers have an important role in ecosystem waters, namely as a deposit feeder. Sea cucumbers can live in shallow waters, such as seagrass ecosystems. The purpose of this study is to knowing the abundance of sea cucumbers in the seagrass ecosystems on the island of Unggeh and to knowing the type of Sea Cucumber. The method used is a transect quadrant method with a size of 5x5 meters, on a transect line with a length of 100 meters. Sampling was done at three points observations, station 1 was at coordinate point 01°34'26,88 «LU and 098°45'40,25» BT, station 2 was at coordinate point 01°34'32,71 «LU and 098°45'37, 58 »BT, station 3 is at the coordinate point 01°34'24,22 LU and 098°45'38,06 BT. The type of sea cucumber found in the seagrass ecosystem on the Unggeh island Actinopyga ecinites, A. Miliaris, Holothuria scabra. The density at station 1 was 0.16 ind / m2, at station II a density was0.12 ind / m2, at station III a density was 0.08 ind / m2, and the total density at the research location was 0, 32 ind / m2.
