Abstract

Foraminifera is one of single-celled protozoa, living in the water environment especially marine waters. This organism can be used as bioindicator of environmental conditions of coral reefs through a simple index called FORAM Index. The purpose of this research are to obtain FORAM Index values​, to know any species of benthic foraminifera bioindicator of coral reefs environmental conditions that have been found and to find out whether there is a relationship between FORAM Index to the condition of coral reefs based on coral coverage percentage. The research used survey method on sediment sampling and measurement of environment parameters by P20 LIPI team in April 2011. Several important steps in this research such as sediment samples preparation, sample observation, and sample identification. The results showed that there were 80 species and 31 genera benthic foraminifera bioindicator of coral reefs environmental conditions were found in the Natuna Islands. The condition of coral reefs in the Natuna Islands based on FORAM Index (FI) values ​​ranged from 2.6 to 5.94, and overall there was a positive relationship between FORAM Index and the condition of coral reefs based on coral coverage percentage i.e., the increase of FI was followed by the increase of coral coverage percentage.  However, in the terms of correlation there were several different results, there was a strong correlation and a weak correlation. Keywords: foraminifera, FORAM index, coral reef.

Abstract

Research of water condition of coral reefs with foraminifera benthic as bioindicator based on FORAM Index (FI) in Banggai Islands, Province of Central Sulawesi was conducted by P2O-LIPI, Jakarta team in July 2011.  This study was an exploratory research, conducted using survey methods. Sediment sampling was collected by a Van Veen Grab and measurement of other biotic and abiotic parameters was performed in 8 point sampling stations scattered in Banggai islands. Sediment samples were analyzed qualitatively and quantitatively to identify the types of foraminifera, determines FORAM Index, and find out  the relationship between FORAM Index with condition of coral reefs views by coral cover. The results showed that foraminifera benthonic as bioindicator were 75 species, which belong to  33 genera. Water conditions of Banggai Islands by FORAM Index (FI) values ​​ranged from 2.99 to 5.54. There was a fairly close relationship between FI with condition of coral reefs views by percentage coral cover in Banggai Islands. Keywords : coral reefs, FORAM Index, foraminifera benthic, Banggai Islands
