Abstract

Seagrass beds are one of the coastal vegetation that is very important as an ecological service, the existence of different characteristics of aquatic habitats can affect the quality of waters, communities and zoning of seagrass grows. The research was carried out in the waters of Gili Maringkik and Poton Bako from September to December 2017. The water quality that differs significantly in both locations is the pH value and amount of dissolved solids, while the temperature, salinity, and dissolved oxygen are not significantly different. The composition of the types of seagrass in East Lombok found amounted to 10 species out of a total of 13 species of seagrass in Indonesia, including: Cymodocea rotundata, Cymodocea serrulata, Enhalus acoroides, Halophila minor, Halodule pinifolia, Halodule uninervis, Halophila spinulosa, Syringodium isoetifolium, Thalassia hemprichii and Thalassodendron ciliatum. The highest species density in both locations was C. rotundata (214.67±110.47 m-2 individuals in Poton Bako and 506.40±187.81 m-2 individuals in Gili Maringkik), while the highest species cover percentage was T. hemprichii (36.52±30.00 %), C. rotundata (33.47±26, 75%) and E. acoroides (31.07±16.24%). The distribution pattern of growth zoning of C. rotundata species has similarities in both locations, while the types of T. hemprichii and E. acoroides are different.
