Diversity Inventory of Associated Biota in Mangrove Restoration and Learning Center, Simeuleu Regency as Public Information

One of the ecological functions of mangroves is as a habitat for various aquatic biotas. The study was conducted in January 2022 at the Mangrove Restoration and Learning Center, Simeulue Regency. The purpose of this study was to determine environmental conditions and the diversity of associated biota species at the Mangrove Restoration and Learning Center, Simeulue Regency. The association of biota data was collected using the census method by identifying each biota found at four observation stations. Parameters of environmental conditions observed were the amount of waste, the amount of felling, pH, temperature, salinity, and DO. Based on the identification results, the associated biota found at the study site were 6 families consisting of 6 species, namely Terebralia palustris, Uca sp., Neritina gagates, Turritella duplicate, Rhizoprionodon acutus, and Vanarus salvator. The dominant association biota found was Terebralia palustris from the class Gastropod. The results of environmental quality observations found 12 logging and 19 plastic wastes, but in terms of water quality, it is still relatively good for aquatic life and following the standard quality parameters for marine waters environment based on the Decree of the Minister of State for the Environment No. 51 of 2004.
