Abstract

This study aimed to determine the content of nitrate and phosphate in water and substrate, to know the type and density of seagrasses and to determine the relationship between the content of nitrate and phosphate in water and substrate to the density of seagrasses in the waters of Tangkil Lampung Island. This research was conducted in April-July 2018 on the waters of Tangkil Island, Lampung Province. Data on seagrass conditions were measured using a square transect size of 50x50 cm2 and measurements of the physical and chemical parameters of the water were repeated three times. The relationship of nutrient content in water and substrate with seagrass density was tested using simple linear regression analysis. The results of the measurement of nitrate content in water ranged from 0,046 mg/l - 0,1035 mg/l and the nitrate content in the substrate ranged from 3, 4875 mg/kg – 4, 8375 mg/kg while the phosphate content in water ranged from 0,0151 – 0,0202 mg/l and phosphate content on the substrate ranged from 6,8625 - 13,1 mg/kg. The highest seagrass density was found at station 4 (99 stands/m2) and the lowest density found at station 3 (52 stands/m2). The relationship between the content of nitrate and phosphate in the water to the density of seagrass had very strong relationship while the content of nitrate and phosphate in the substrate had weak relationship.
