Abstract

Ocean acidification afected marine organisms especially calcifying organisms, such as Halimeda sp. This study was conducted on June to September 2012 at laboratory of Research Center and Development for Marine, Coastal and Small Islands, Hasanuddin University. The aim of study to determine the efect of acidic level on Calcium concentration and growth rate of calcifying macroalgae, Halimeda sp. The experiment design was used completely random design with three treatments and three replicates. Analysis variance was used for data analysis with advanced respon test. Tukey test was used to compare the diference between treatments. Water quality parameters were analyzed descriptively. The results showed that there was a significant diference of pH treatments on calcium concentration an d growth rate of Halimeda sp. The highest calcium concentration was found at pH 8. In conclusion, increasing pH level of media disturbed the calcifying process of Halimeda sp especially at pH level of 6, while growth rate of Halimeda sp was not afected wit h the decreasing of pH.
