APLIKASI MODEL DINAMIK DAMPAK EUTROFIKASI DAN SEDIMENTASI BAGI PENGENDALIAN KERUSAKAN TERUMBU KARANG DI PERAIRAN SULAWESI SELATAN
Abstract: The aplication of
dynamic model to describe the effect of eutrophication and sedimentation on
coral reefs damage in a wider scope. The trial were performed in two main areas
of coral reefs in South Sulawesi, namely in Spermonde Archipelago and in
Sembilan Archipelago in Bone Bay. Retrieval of data include measurements of
water quality (nitrate and phosphate concentration) and the rate of
sedimentation. While collecting of ecological data, namely macroalgae cover,
coral reef cover, and species of herbivores and its abundance. Data was
collected on monthly for 4 months at six stations/islands. The data was taken
at two points on each island as replicates. Oceanographic data were taken every
month, while the ecological data were taken at the end of the study. Nutrients
concentration (nitrat and phosphat) and sedimentation rate were measured in
laboratory. The result of the model test showed that the developed model is
valid and broad-spectrum and therefore can be applied to other areas already
impacted by eutrofi cation and sedimentation. The results of the execution of
the model shows that all stations on the island leads Phase shift, namely the
dominance of macroalgae cover in the future (about 2-4years in the future).
