Abstract

The coastal waters of the Strait of Makassar are classified as a productive coastal area, in which there are mangrove ecosystems, seagrass beds and Spermonde coral reefs that play a crucial role in sustaining the economic life of coastal communities and food security. Our previous results have calculated the outflow of nutrient land to sea with nitrate concentrations ranging from 0.01-0.44 mg/L and phosphate 0.04-0.35 mg/L. This condition has caused coastal waters of permonde to be eutrophicated with the occurrence of mass death of several species of fish and the emergence of dangerous microalgae species. This study aims to calculate the current nutrient value in the area of ​​seaweed cultivation as a biological absorber. Based on the interim results, the decrease or absorption of nutrients by seaweed ranges from 0.08-1.55 mg/L-nitrate and 0.01-0.71 mg/L-phosphate.
