Fatty acid map of various species seagrasses on the Donggala Beach

Abstract

Quantitative identification of seagrass fatty acids has been carried out from the species of Thalassodendron ciliatum, Cymodocea rotundata, Cymodocea serrulata, Thalassia hemprichii, and Enhalus acoroides. Fat analysis samples taken in Donggala regency aquatic is done by the Soxhlet method and analysis of fatty acids using by the GC method. It was found that variations in fat content were between 0.27% - 1.01%, while the saturated fatty acid concentrations found varied between 4.39% - 8.03%, unsaturated fatty acids varied between 4.48% - 18.39%, and omega 3 (EPA) varies between 0.27% - 1.24%. If seagrass fatty acid data is combined with the results of protein, phosphate, and minerals analysis data, it can be the basis for estimating the fertility status of seagrass and the healthy environment of a region, especially the coastal aquatic of Donggala regency.
