Abstract
Macroalgae research in Anambas Islands that is the reef flats Jemaja, Pemutus and Matak Waters was carried onJune 2005. Survey method on the research using quadrat transect. Macroalgae is a marine flora which containsChlorophyceae, Phaeophyceae and Rhodophyceae. Biodiversity in the research location was 18 species. Thehigher diversity index (H) was 0.24 and equitability index (e) was 0,105. The higher density of species were 207individuals. Dominant species was 22,83% by Sargassum polycystum.

Summary
Penelitian makroalgae di perairan pantai paparan terumbu karang di Pulau-Pulau Kepulauan Anambas dilaksanakan pada bulan Juni tahun 2005. Data lapangan diperoleh dari pencatatan hasil sampel penelitian. Metode dengan survey menggunakan transek kuadrat di masing-masing stasiun ditarik garis tegak lurus pantai ke arah tubir. Setiap m diplot dengan frame alumunium 1x1m2 diambil sampelnya dan masing-masing spesies dihitung individunya per bonggol (holdfast). Penamaan jenis makroalgae diidentifikasi berdasarkan Taylor (1967) dan Trono & Fortez (1988). Keragaman jumlah jenis dan individu dalam 1 m2 dihitung menggunakan rumus Shannon (1948) dengan indeks Keragaman (H). Kemerataan jenis menurut Pielou (1966) untuk mendapakan indek kemerataan (e)sebagai berikut: H. H = Shannon indeks; n = Jumlah jenis; ni = jumlah total sampel individu ke-i
