Abstract

Purpose of this research is to know the community of seagrass, and physical-chemical parameters in the South Bangka island, North Minahasa Regancy, North Sulawesi Province. Data retrieval by the random sampling of systematic method on three lines transect with 50 m long, and 30 quadrants. Data taken in each quadrant is number of species and number of individuals of each species. Results of the measurement of physical and chemical parameters of static waters associated with the feasibility of life for water organisms in it, generally in good condition. Ten species of seagrass have been found in the southern part of the island of Bangka. Four species are always found in any transek i.e Syringodium isoetifolium, Cymodocea rotundata, Enhallus acaroides, and Halophylla ovalis. The highest found in seagrass cover transek 1 i.e. 67.00% while the lowest in transek 3 i.e. 46.30%. Seagrass cover Enhallus acaroides in Bangka island very prominent compared to other species. Based on the current index value is important, Syringodium isoetifolium have a high importance value index only in the transek 3 which means this type of seagrass seagrass types affect other takes part in community level. Ecological index results suggest that the ecosystem of seagrass in Bangka island in the southern part of the State is stable.
