Penelitian ini bertujuan untuk mengetahui pengaruh intensitas dan lamanya pemaparan pencahayaan UV terhadap laju pelepasan Zooxanthellae pada karang Acropora sp serta recovery nya. Penelitian dilaksanakan pada bulan Desember 2018 – Januari 2019, di Laboratorium Histopatologi BBPBAP Jepara. Spesimen karang Acropora sp. diberikan perlakuan penyinaran secara Fotoperiode dan terus-menerus dengan lampu uv 10 watt, 15 watt dan kondisi normal; dengan ulangan tiga kali. Sampel karang Acropora sp. diambil dari perairan Pulau Panjang Jepara. Pengamatan dilakukan pada interval waktu ke- 0, 12, 24, 36, 48, 60, dan 72 jam.

The research was carried out in December 2018 to January 2019, in the Histopatologi Laboratory of BBPBAP Jepara. Coral Acropora sp.

The main parameters observed are the release of Zooxanthellae and water quality as supporting variables. The result showed that the intensity of ultra violet lighting influence significantly on the release of Zooxanthellae.
