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

Natuna Islands cluster consisting of large and small islands which a very diverse ecosystems are occurred, including mangrove, seagrass and coral reefs. These waters can be a conducive habitat for various marine organisms, including foraminifera that can live in all types of waters. Collected foraminifera from a site reflect the relationships between species that are affected by ecological factors and the ability of these organisms adapt to their environment. These organisms are also used in the petroleum and mining line, and studied in the micropaleontology and palaeoecology. Therefore, the data on foraminifera in a marine community, including the waters of Natuna Islands are very important to support the fields. Sampling of this study was conducted in April 2011 in the waters off the coast until the ocean waters covering Bunguran, Subi Besar and Laut Islands. The benthic foraminifera that was collected as abundant in these three waters is symbiont bearing foraminifera, namely Amphistegina lessonii.Keywords: Assemblage, foraminifera, benthic and Natuna

Arafura Sea consists of shallow waters and located in the Southern of Papua to the north coast of Australia. The waters is vegetated by shallow-water ecosytems such as mangrove, seagrass bed, and coral reefs. The Arafura continental shelf is predominated by sediment from late Paleozoic, Mesozoic to Cenozoic and underlain by granitic basement. Foraminifera is a single cell microorgainsm, has pseudopodia with high level of diversity. Foraminifera dwells in every level of sea depth, from estuary to the deep sea. However, a certain species commonly dwells in the specific profundity. The aim of the study was to recognize the distribution of benthic foraminifera in the waters of Arafura Sea and it relation with the environmental characteristics. As many as 11 sediment samples was collected in May 2010 from the water of Arafura Sea using a box core with capcity of 0,3 m3. Laboratory analyses on the colleted samples were performed to determine the type of sediments and identify the benthic foraminifera, and to determine the abundance of each samples. The number of species found from the collected sediments were 37 species consisting of 29 genera of which most of them were member of Suborder Rotaliina and many of them belong to Suborder Miliolina and Textulariina. The most common species of the sampling sites were Ammonia beccarii and Pseudorotalia schroeteriana. The Arafura Sea commonly recognized as shallow waters, open seas, with current speed of midium to high. The predominant sediment type of the waters is sandy mud and little of clay.Keywords: distribution, benthic foraminifera, sediment and Arafura

Foraminifera are generally live in sea water with various sizes. These organisms consist of planktonic and benthic foraminifera. Geological activity on plutonic and volcanic with vomiting magma is transpiring on, and then affects sedimentation and foraminiferal abundance of Ambon Bay. The study was determined to study the abundance and distribution of foraminifera based on the sediment characteristic of Ambon Bay. Sample collected in 2007 of Ambon Bay showed that only 29 samples of 50 samples containing foraminifera. The collected sediments have 86 species of foraminifera, consisting 61 species of benthic foraminifera and 25 species of planktonic foraminifera. The dominant benthic foraminifera in the surface sediment of Ambon bay were Amphistegina lessonii, Ammoniabeccarii,Elphidium craticulatum,Operculina ammonoides and Quinqueloculina parkery. The planktonic foraminifera that were frequently collected from the bay were Globorotalia tumida, Globoquadrina pseudofoliata, Globigerinoides pseudofoliata, Globigerinoides cyclostomus dan Pulleniatina finalis. Generally, the species dwelled as abundant on substrate sand, whereas the areas within substrate mud have no foraminifera lie on them. Keywords: Foraminifera, Abundance, Sediment, Ambon Bay

To check the feasibility of the environmental for coral reefs, several monitoring strategies exist, one of which making use of the foraminiferal community structure: FORAM Index, i.e. Foraminifera in Reef Assessment and Monitoring Index. The abundance of symbiont-bearing foraminifera should parallel coral abundance, if water quality is the major environmental control. This allows for the use of these foraminifera to quantify environmental quality with respect to coral health. The aim of this study is to study the benthic foraminiferal assemblages in coral reefs community and sea grass bad of Belitung Islands and to use that information to determine the environmental quality of their coral reefs based on FORAM Index. Sediments of Belitung Islands waters were sampled for their foraminiferal fauna at six sites i.e. Nasik Strait (four sites), Kudus Island and Bago Island on April 2010. Results of benthic foraminiferal quantitative analysis of the sediments in which collected from six sampling sites of Belitung Islands show that totally collected specimens 29 species of 18 genera. The most favorable place for coral growth is the free area (absence of coral, mangrove and seagrass) of Nasik Strait, but it only has 30 specimens of benthic foraminifera, with three species of symbiont-bearing foraminifera such as Operculina and Amphistegina. Whereas, the most abundant of benthic foraminifera is Nasik Strait 1 with typical substrate coarse sand and vegetated by coral reef. In other side, segrass bad of Nasik Strait is dominated by opportunistic foraminifera and only dwelled by Heterostegian, Calcarina, Elphidium, Ammonia, Acervulina, Spirolina, Quinqueloculina and Lenticulina. Moreover, the most abundant species of all sampling sites is Peneroplis pertusus.
