Variety of Caulerpa sp. has important benefits in ecological, economic, and cultural aspects, so they need to be protected and preserved. This research aims to: (1) identify the diversity of Caulerpa sp. found in Kangean Island; (2) analyze the population distribution pattern of Caulerpa sp. in the Arjasa District of Kangean Island, Sumenep Regency; (3) Utilize the results of identification of species Caulerpa sp. in Island Kangean as a source for learning biology. The method in this research is a qualitative and quantitative descriptive research method. Research result; (1) The diversity of Caulerpa sp. found in the white sand beach area of ​​the Kangean Islands consists of the types Caulerpa racemosa, Caulerpa lentillifera, and Caulerpa sertularioides; (2) the distribution pattern ranges from 0.44 to 0.20 or IM value < 1, which means that the distribution pattern of all types of Caulerpa sp. in the White Sand Beach area of ​​the Kangean Islands is even; (3) The results of identifying diversity in the Kangean Islands can be used as a biology learning resource on the subject of Sea Grape Variety.
