Highlight Calculated and assested the percentage of live coral coverIdentified reef fishes and calculated fish abundanceMeasured physical and chemical oceanography parameter Analyzed carrying capacity and suitability of Unggeh Island for tourism utilization especially marine diving and snorkeling.AbstractUnggeh Island located in the administration of the Village Sitardas Badiri District, Central Tapanuli Regency into a marine tourism area. The development of marine ecotourism Unggeh Island is an alternative to the economic improvement of so- ciety. This study aims to assess the potential of coral reef ecosystem in the form of percentage of life form coral, coral species and species and abundance of reef fish found in Unggeh Island waters of Central Tapanuli Regency and to analyze the suitability of coral reef ecosystem in Unggeh Island for tourism utilization es- pecially marine diving and snorkeling. Coral reef community data collection was done by using SCUBA divers equipment, in identifying The coral community used underwater photo transect (UPT) method, while coral fish diversity was observed by underwater visual census (UVC) method. Physical and chemical oceanography parameter data such as temperature, salinity, pH, current, transparency and DO are performed at each observation station. The survey results of coral reef observation at four stations showed different results. Percentage of live coral cover of station 1 to 4 were 25.40 %, 12.33%, 28.53%, and 25.53 respectively. Therefore, reef fishes found 36 species that consist of ten families and 423 individual fishes. The results showed that Unggeh Island was suitable (S2) for diving and snorkeling activities, with the carrying capacity was 3.054 persons/day.

Reef Ecosystem

Krueng Raya waters have a big potency on coral reef fish; However, there was no study was conducted to document this biodiversity. This data are crucial for the conservation plan. Therefore, the objective of the study was to examine the community structure of reef fish in the Krueng Raya coastal waters, Mesjid Raya Subdistrict, Aceh Besar, Indonesia. The sampling was conducted from January 2014 to December  2016. The data were collected at three stations by the Visual Census method with a depth of 3-4 meters. The research found the average amount of reef fish was 1743 individuals that were consisted of 93 species and comprised of 26 families. The Families dominating were Pomacentridae, Acanthuridae, Chaetodontidae, and Labridae. The distribution level of reef fish individually was influenced by the environmental conditions of the coral reef ecosystem. The severe condition of the coral ecosystem in the Krueng Raya coastal waters was caused by two factors. Firstly, fishing activities of the locals and tourists who deliberately stepping on the coral colonies and using unfriendly tools to catch the fish (speargun). Another factor was the occurrence of coral bleaching in 2016, of which almost 80% of the coral ecosystem in the Krueng Raya coastal waters was exposed to this phenomenon (bleaching).Keywords: Reef Fish, Acanthurida,  Communities Structure, Krueng Raya

Composition and distribution of foraminifers are affected by human activities and have close association with coral reef ecosystem. The aims of this research were to investigate the benthic foraminifers’ composition and distribution in sediment of coral reef ecosystem. Eleven stations of Karang Bongkok, Pramuka, and Onrust Island were observed in this study. The sediments were taken from surface substrate up to 2 cm under the substrate. Samples were washed on sieve with mesh size 0,063 mm, and then dried in oven with 50°C of temperature  for two hours. After separating from the sediment, the foraminifers were laid on foraminiferal slide and indentified using binocular microscope. The highest composition of symbiont-bearing foraminiferal assemblages which associated with reef ecosystem was in East Pramuka (78.17%) and the lowest was in South Onrust (21,83%). The opportunistic type had the highest composition in South Onrust (38.67%) and the lowest was in South Karang Bongkok. In west Pramuka had the highest composition of heterotrophic type (57.17%) and the lowest was in North Onrust (11.33%). Onrust Island was dominated by opportunistic type, indicating high nutrient. The highest amount of foraminifers’ taxa was found in Karang Bongkok with good coral reef coverage, while the lowest in Onrust facing with Jakarta Bay. Keywords: composition, distribution, benthic foraminifers, coral reef.
