Abstract

The dangerous toxins developed by dangerous algae are known as dangerous algal blooms. This phenomenon functions like a food chain, namely the complication of habitats that use toxic algae; this toxicity does not directly affect the first consumer but increases the second and subsequent consumers.Hazardous algae have been found in the Asian region in the 1980's, and Indonesia recorded in 2004. In 2008 there was the phenomenon of mass death of fish when there was a phenomenon that had no known cause.The purpose of this study is a preliminary study that discusses a dangerous phenomenon, namely growth carried out by counting and calculating the number of funds on Banyuwangi Beach. Mass phenomena were discovered during the study. This is suspected because it involves other planktons in this case diatoms can compensate for the need for algae that are classified as dangerous. The results obtained by plankton which are classified as dangerous algae (classified into dinoflagellate plankton) were found to be highest in zone B in April (22.22% of all plankton found) and June (33.33% of all plankton found). Extreme water at Bomo Beach was revised with COD fluctuations which increased in May in zone B which was 2475.77 mg/L.
