The study of association biota in the Seribu Islands mangrove reforestation area was conducted in March 2014 on Pramuka, Panggang and Karya Island with the aim of providing information to the association's biota community after mangrove reforestation. Association biota data is collected by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. Then the line transects are made of plots of size 10 x 10 m 2 and in the size of 10 x 10 m 2 a small plot of 1 x 1 m 2 is made. The results showed that there were 6 associated biota species, of which Littoraria scabra and bivalve gastropods Saccostrea cucullata were scattered in all stations, while cesarean mammal crabs Metopograpsus latifrons and Nerita albicilla gastropods were only found in one observation station. In addition, the composition and density of the highest association biota were found in L. scabra gastropods, the diversity of associated associations was relatively small (low), dominance dominated by gastropod L. scabra, uniformity in depressed conditions regular and clumped distribution patterns. Keywords: Association biota, reforestation, mangrove, Seribu Islands I. Pendahuluan Jupriyati et al. (2013) menyatakan bahwa ekosistem mangrove memiliki tingkat produktivitas yang paling tinggi dibandingkan dengan ekosistem pesisir lainnya. Kemudian, juga memiliki relevansi ekologi yang sangat besar (Valiela et al. 2001, Bouillon 2011) dalam melindungi pesisir pantai, mendukung perikanan, menyimpan karbon, menyediakan kayu, meningkatkan kualitas air dan memberikan kesempatan untuk berwisata (Ewel et al. 1998, Barbier et al. 2011, Lee et al. 2014). Menurut Barbier et al. (2011) nilai ekonomi ekosistem mangrove dapat mencapai US$ 14000 – 16000/ha/tahun, dimana manfaat layanan ekosistem mangrove di Asia Tenggara setara dengan US$ 4200/ha/tahun (Brander et al. 2012). Selain itu, penghasilan dari sumberdaya mangrove setara dengan 30% dari pendapatan rumah tangga di India
