Abstract

ABSTRAK

Penelitian ini bertujuan untuk mengetahui tutupan karang keras pada waktu sebelum (tahun 2015) saat (2016) dan sesudah pemutihan karang (2017) di Krueng Raya, Aceh Besar. Penelitian ini dilakukan pada bulan April 2017 di Krueng Raya, Aceh Besar. Pengambilan data dilakukan di 3 stasiun pengamatan menggunakan metode PIT (Point Intercept Transect) yang meliputi: Benteng Inong Balee, Ahmad Rhang Manyang, dan Lhok Mee. Hasil penelitian menunjukkan persentase rata - rata tutupan karang keras tahun 2015 sebesar 52,83% berkategori baik, tahun 2016 sebesar 32,43% berkategori sedang dan tahun pada tahun 2017 persentase tutupan karang keras menjadi 22,90% dan masuk ke dalam kategori rusak. Terdapat sebanyak 16 genus karang (2015), 18 genus karang (2016) dan 8 genus karang 8 (2017). Indeks Mortalitas (IM) tahun 2015 berkisar antara 0,02-0,20 (tingkat kematian karang yang rendah), tahun 2016 berkisar antara 0,13-0,49 (kematian karang rendah), tahun 2017 berkisar antara 0,63-0,79 (tingkat kematian karang tinggi). Hasil penelitian ini menunjukkan bahwa persentase tutupan karang keras mengalami penurunan hingga mencapai ±50% yang diakibatkan oleh pemutihan karang pada Perairan Krueng Raya Aceh Besar.

 

ABSTRACT

The aim of this study was to determine hard coral cover at the time before (2015), during (2016) and after coral bleaching (2017) in Krueng Raya, Aceh besar. This study was conducted on April 2017 in Krueng Raya, Aceh Besar. Data collection was carried out at 3 observation stations using the PIT (Point Intercept Transect) method which included : Fort Inong Balee, Ahmad Rhang Manyang, and Lhok Mee. The results showed that the average percentage of hard coral cover in 2017 was 22.90% (bad category), it was lower than in 2016 32.43% (medium category) and in 2015 was 52.83% (good category). There were found 16 genera of coral (2015), 18 genera of coral (2016), and 8 genera of coral (2017). Mortality Index (MI) in 2015 ranged between 0.02-0.20 (low coral mortality rate), in 2016 ranged between 0.13-0.49 (low coral mortality rate), in 2017 ranged between 0.63-0.79 (high coral mortality rate). The results of this study indicate that the percentage of hard coral cover has decreased to reach 50% due to coral bleaching in the waters of Krueng Raya Aceh Besar.
