The method of  this  research used  was as experimental method by completely randomized design (CRD) using one factor and  4 levels of (P1= 0-5 years), (P2= 6-10 years ), (P3= 11-15 years) , (P4= 16-20 years ) and 3 repetitions. The result of the research was showed of the 10 spesies were found consisting Cyanophyta, Clorophyta and Xanthophyta (5 spesies, 4 spesies,and 1 spesies) respectively.
