This study aims to determine the types and abundance of epiphytic diatoms, analyze abundance indices between stations, and analyze diversity, dominance, and evenness indices of epiphytic diatom species on Thalassia hemprichii seagrass leaves. This study was conducted in March 2025 in the waters of Cindakir Beach, Kabung Bay, West Sumatra, using the survey method. Based on the results of the study, 14 species of epiphytic diatoms were found, namely: Nitzschia sp., Cymbella sp., Cocconeis sp., Flagilaria sp., Meridion sp., Licmophora sp., Gyrosigma sp., Navicula sp., Pleurosigma sp., Pinnularia sp., Synedra sp., Rhizosolenia sp., Surirella sp., and Amphora sp. The most frequently found species with the highest abundance were Rhizosolenia sp. and Nitzschia sp. The abundance of epiphytic diatoms ranged from 1,287-6,648 ind/cm², with significant differences in abundance between stations. The diversity index (H') ranged from 0.9254-2.2010 (moderate category), the dominance index (C) ranged from 0.2364-0.6566, with the dominant species at Station I, and the evenness index (E) ranged from 0.5845- 0.9855, indicating that the evenness of diatom species in the waters of Cindakir Beach is relatively stable.
Keywords : Epiphytic diatoms, community structure, Seagrass leaves, Thalassia hemprichii, Cindakir Beach.
