“…Tekanan lingkungan akibat aktivitas manusia yang berlangsung di daratan dapat mempengaruhi ekosistem perairan sekitarnya sehingga menurunkan keanekaragaman hayati khususnya di daerah ekosistem terumbu karang (Burke et al, 2002;Siringoringo et al, 2013). Selain itu faktor alam seperti naiknya suhu perairan melebihi batas normal toleransi terumbu karang menyebabkan terjadinya pemutihan karang (Octavina et al, 2018;Ulfah et al, 2018).…”

This study aims to analyze the condition of the coral reef ecosystem including the substrate, genus composition, and the level of coral mortality in the waters of the Malacca Strait, Masjid Raya District, Aceh Besar District. The research was conducted from October 2016 to October 2019 in the waters of the Malacca Strait, Masjid Raya District, Aceh Besar District. The research site is divided into three stations consisting of Lhok Mee Station, Ahmad Rhang Manyang and Benteng Inong Balee Station. Data were collected using the Point Intercept Transect method. The results showed that the condition of coral reefs at Lhok Mee Station was in the damaged category with coral cover ranging from 6.56% - 13.44%. Ahmad Rhang Manyang Station is included in the moderate to good category with coral cover ranging from 38.75% - 67.19%. Meanwhile, Benteng Inong Balee Station is included in the medium category with coral cover ranging from 45.94% - 56.88%. The monitoring results found that 30 coral genera with the highest composition of the coral genera came from the Porites genus, while other coral genera were unevenly distributed. The value of the mortality index for Lhok Mee Station shows a high increase in mortality of live coral to dead coral. Meanwhile, Ahmad Rhang Manyang and Benteng Inong Balee stations have low coral mortality index values.

“…Wouthuyzen et al (2020) juga meneliti dampak pemutihan karang tahun 2016 di TWP Pieh bahwa tutupan karang hidup turun dari 41,40% (tahun 2015) menjadi 28,38% (tahun 2016). Penelitian yang sama juga dikemukan oleh Ulfah et al (2018) menjelaskan telah terjadi penurunan tutupan karang keras yang significant sejak tahun 2015 sebesar 52,83% (kondisi baik), di tahun 2016 sebesar 32,43% (kondisi sedang) dan berlanjut di tahun 2017 menjadi 22,90% (kondisi rusak). Ampou et al (2017) Komponen bentik yang digunakan untuk menghitung indeks kesehatan terumbu karang adalah fleshy seaweed (makro alga), pecahan karang mati (rubble) dan tutupan karang hidup ( Tabel 6 ).…”

Coral reefs condition in the protected marine area at Selat Bunga has decreased every year. The health of coral reefs is represented by coral index health. The purpose of this study was to analyze the coral reefs health index based on the condition of live coral cover, resilience level and condition of coral fish. Retrieval of coral reefs data using the Under Photo Transect Method and coral fish data collection using the Under Water Visual Census. The results of research at 9 research stations found that the average cover of live coral ranged from 1.40 - 44.68%, fleshy seaweed ranged from 0.13% - 12.87%, rubble ranged from 1.73 - 39.40%, and average total reef fish biomass ranged from 8.93 - 253.23 kg/ha. Coral reef health index values range between 3-6. Coral reefs health index of 67% of research stations is 3. The coral health index value 3 is indicated by a low percent live coral cover, a high resilience rate, and a low reef fish biomass.Kondisi terumbu karang di Kawasan Konservasi Taman Wisata Perairan (TWP) Selat Bunga Laut telah mengalami penurunan setiap tahun. Indeks kesehatan karang adalah nilai yang mengambarkan kesehatan karang antar lokasi penelitian. Tujuan penelitian ini adalah menganalisis indeks kesehatan terumbu karang berdasarkan kondisi tutupan karang hidup, tingkat resiliensi dan kondisi ikan karang. Pengambilan data terumbu karang dengan metode Under Photo Transect dan pengambilan data ikan karang mengunakan Under Water Visual Census. Hasil penelitian di 9 stasiun penelitian didapatkan persen rata-rata tutupan karang hidup berkisar 1.40- 44.68 %, fleshy seaweed berkisar 0.13% - 12.87%, pecahan karang berkisar 1.73 –39.40 %, dan rata-rata total biomassa ikan karang berkisar 8.93 – 253.23 kg/ha. Nilai indeks kesehatan terumbu karang berkisar antara 3-6. Sebanyak 67% stasiun penelitian mempunyai indeks kesehatan terumbu karang dengan skala 3. Indeks kesehatan karang skala 3 ditunjukkan oleh persen tutupan karang hidup yang rendah, tingkat resiliensi yang tinggi dan biomassa ikan yang rendah.

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
