UNVEILING MEIOFAUNA DIVERSITY: A STUDY OF COMMUNITY STRUCTURE AND ABUNDANCE IN UNRECLAIMED AND RECLAIMED SHORES, SERANGAN ISLAND, BALI, INDONESIA
Serangan Island is a small island that administratively located in South Denpasar District, Town of Denpasar, and Province of Bali. All of Serangan Island region stated as a village that named Serangan Village which have 4435 peoples. Because Serangan Island is tourist destination, so Serangan Island certainly exposed by tourism development process. As a part of tourism development process is shore reclamation process, an effort to widening Land of Serangan Island which has occured in 1997. That reclamation has enough change environment landscape in Serangan Island. Environment change in shore of Serangan Island, estimate have impact on meiofauna community that life in Serangan shore. Two aspects of meiofauna lives that estimated impacted by reclamation process in Serangan shore are diversity and abundance. To obtain a certainty of reclamation impact to meiofauna live, we have done research about impact of reclamation process to meiofauna live in Serangan Island. In this research, we design this research as a field study. We collect meiofauna samples in two different shores condition, that is shore that impacted reclamation in one side, and shore that no impacted reclamation in the other side. Meiofauna samples collected by core which collected in nine points for each shore condition. Meiofauna extracted by elutriation method, and then meiofauna preservated by 5 % formalin solution. Meiofauna observed and identified by microscope. Then, meiofauna data analyzed by statistical approach by use t-test formula and Shannon Wiener formula for diversity indices. The results of this research are ; 1) meiofauna diversity in shore that impacted by reclamation lower significantly than meiofauna diversity in shore that no impacted by reclamation ; 2) meiofauna abundane in shore that impacted by reclamation lower siginificantly than meiofauna abundance in shore that no impacted by reclamation.
