Dampak Pemutihan Karang Tahun 2016 Terhadap Ekosistem Terumbu Karang: Studi Kasus Di TWP Gili Matra (Gili Air, Gili Meno dan Gili Trawangan) Provinsi NTB Coral Bleaching Impact in 2016 Towards Coral Reef Ecosystem: Case Studies TWP Gili Matra (Gili Air,

ABSTRACT Increased sea surface temperatures due to global warmingthat occurred from the early to mid 2016 caused of coral bleachingin several locations in TWP Gili Matra. Observations of coral bleachingobtained from coralcolonies compotition affected by bleaching(50%), white (18%), death (1%) and was not affected (31%). These implications resulting decline in coralcover but not significant (F (1,013) = 0.333, p > 0.05) from 23,43% ± 2,61 SE in 2012 to 18,48% ± 4,14 SE in 2016 and a significant decrease (P (58,06) = 3,8e -06 ) recruitment of coral( coralJuvenil) from 6,66 ind.m -1 ± 1,04 SE in 2012 to 1,41 ind.m -1 ± 0,16 SE in 2016. the other impact is a significant reduction (P (20.84) = 0,00053, p 0.05) from 506,56 kg.ha -1 ± 99,05 SE in 2012 to 438,41 kg.ha -1 ± 45,69 SE in 2016. The decline of coralrecruitment resulted in the recovery of the affected areas bleachingbecomes slow because of the juvenile new coralmostly dead. The second impact of bleachingis an abundance of fish decrease, indicating that is available only fish big size (adult) and very less of small fishes, including juvenile.
