Abstract
Padang lamun selalu menjadi habitat yang banyak ditempati oleh berbagai organisme laut, salah satunya yaitu epifit yang hidup saling terikat dengan lamun yaitu dengan menempel pada rhizome, batang dan daun lamun. Tetapi dengan kondisi mikroepifit yang sangat banyak dapat memperlambat proses fotosintesis bagi lamun. Penelitian ini bertujuan untuk mengetahui struktur komunitas mikroepifit yaitu kelimpahan jenis mikroepifit, komposisi jenis mikroepifit, keanekaragaman, keseragaman dan dominansi jenis mikroepifit pada padang lamun di perairan Pelabuhan Feri Tomia, Desa Kollo Soha, Kecamatan Tomia, Kabupaten Wakatobi. Pengambilan stasiun penelitian dilakukan dengan memakai metode purposive sampling dan stasiun yang didapatkan yaitu tiga stasiun. Pengambilan sampel daun lamun menggunakan transek kuadran 1 m2. Sampel mikroalga epifit didapatkan dengan dilakukannya metode pengerikan. Penelitian menunjukan hasil bahwa mikroepifit yang ditemukan terdiri dari 24 jenis yang tergolong dalam 6 kelas dan 24 famili. Kelimpahan tertinggi terdapat pada stasiun 3 dan terendah terdapat pada stasiun 2, keanekaragaman mikroepifit untuk setiap stasiun sedang, keseragaman mikroepifit pada stasiun 1 dan 2 dalam kategori sedang, sedangkan pada stasiun 1 tergolong stabil, dan domininasi mikroepifit untuk setiap stasiun juga masuk dalam kategori sedang. Posisi penempelan mikroepifit pada bagian lamun memiliki pengaruh terhadap kelimpahan mikroalga epifit.
