摘要：Kepulauan Seribu is a well-known destination of marine tourism in Indonesia. Inevitably, the place has been affected by human activities. Hence it is important to preserve and conserve the area so as it is still suitable for reef community to grow and develop. One of the methods to evaluate the feasibility for reef environment is calculated by FoRAM Index (FI) values. Benthic foraminifera as a tool for environmental bioindicators were collected from 15 marine surface sediment samples in the vicinity areas of Kotok Besar, Kotok Kecil and Karang Bongkok islands in Kepulauan Seribu to assess the FI values. Approximately 20 genera of benthic foraminifera were found in the study area. The genera are dominated by Amphistegina and Calcarina along with Operculina, Quinqueloculina, Peneroplis, and Discorbis. The finding signifies reef flat environment as the dominant morphology, although the presence of fore slope is also observed particularly at the western part of Kotok Besar island. The assemblages of Operculina and Quinqueloculina suggest that the abundance of benthic foraminifera is influenced not only by the morphology of seafloor, but also by tidal current and terrestrial influence. The FI formula using foraminifers found in the study area results values above 4, thus the area can be reviewed as a decent environment for reef growth and development.
