Abstract

The condition of seagrass beds in a water body can be determined by assessing seagrass cover. Remote sensing is a method that has been widely used to map and monitor seagrass cover. Environmental factors such as sediment characteristics and water quality have a great influence on seagrass conditions. This study aims to determine the influence of water quality on seagrass cover mapping in Buhung Pitue Island, Sinjai Regency. Seagrass cover mapping uses Landsat-8 satellite images with maximum likelihood classification, while the water quality analyzed is turbidity, TSS (Total Suspended Solid) and TDS (Total Dissolve Solid). Based on the results of the study, seagrass cover was dominated by the dense seagrass category (51-75%). The turbidity analysis results were 0.25 - 1.6 nTU, TSS was 6 - 58 mg/L and TDS was 58 - 64.5 mg/L. The three results of water quality measurements do not exceed the threshold of seawater quality standards for biota according to the Decree of the Minister of Environment No. 51 of 2004, so it does not affect the mapping of seagrass cover.
