Abstract

Shrimp-seaweeds polyculture is a model of sustainable ecosystem. The aim of this system is to increase water quality and shrimp production. This research is to test the efectivity of shrimp-life Sargassum and shrimp-Sargssum extract. The reason in using of Sargassum extract is to increase shrimp production, as this seaweeds produce phlorotanin that is effectively kill several pathogenic bacteria. Hereby, the addition of Sargassum extract will also affect oxygen concentration and pH. Therefore, it is important to analyze its effect on dissolve oxygen and pH. Results indicated that, the presence of life Sargassum increased oxygen concentration and pH at the beginning. However, destruction of life Sargassum by rain was ended in reduction of both, dissolved oxygen and pH. Addition of Sargassum extract reduced dissolved oxygen and pH. It was predicted that Sargassum extract would increase the content of organic material that stimulate oxygen consumption during degradation process. However, the presence of phlorotanin also inhibit degradation process, therefore it is degraded slowly.
