Abstract

Destructive fishing such as using cyanide in capture of ornamental fish has caused damage to the coral reefs, this is suggested the use of clove oil which considered eco-friendly fishing. This study aims to analyze the changes of color, zooxanthellae density and mitotic index of coral Porites lobata after exposure to several concentrations of clove oil. Experimental design was a factorial design, which consists of six concentrations and five time treatments with 3 replication. Coral was placed into the 1.0x0.5x1.0 m aquarium that contains clove oil solution in different concentrations (control, 20, 30, 40, 50, and 60 ppm) for 5 min and then transferred to a tank containing clean seawater for 60 seconds and then removed to tanks for the recovery process. Observation was made everyday for coral color changes in 17 days period and on day 1, 5, 9, 13 and 17 for zooxanthellae density and mitotic index.  The results showed that the were no changes in Porites lobata colors until the 17th day after exposure to 20–60 ppm of clove oil and there was no significant difference in the zooxanthellae density and mitotic index of the Porites lobata on concentration variation, while zooxanthellae densities and mitotic index showed significant difference on time (day) variation. This suggested that exposure to clove oil at  a concentration of 20–60 ppm did not affect the color change, zooxanthellae density and mitotic index of Porites lobata.

Abstract

Kecamatan Ujungbulu merupakan salah satu sentra rumput laut di Kab. Bulukumba yang memberikan peluang usaha yang sangat baik bagi peningkatan perekonomian keluarga. Keberhasilan budidaya rumput laut sangat dipengaruhi oleh musim, teknik dan metode budidaya yang tepat sehingga dapat memberikan pertumbuhan yang maksimal seperti pola tanam yang sesuai, penerapan metode tali bentang atau long line. Namun dalam perkembangan metode ini, Masih banyak masalah yang dihadapi oleh pembudidaya, seperti bobot awal bibit yang terlalu besar, jumlah bentangan per awal penanaman per areal yang terlalu banyak, dilakukan penanaman awal yang bersamaan dan penggunaan areal budidaya secara bersamaan per kelompok petani budidaya. Melalui program pengabdian kepada masyarakat dosen PS. BDP, maka dilakukan Penyuluhan Metode Budidaya Rumput Laut. Kegiatan ini dilakukan di Kantor Lurah Kalumeme, Kecamatan Ujungbulu, Kabupaten Bulukumba pada Sabtu 26 Oktober 2024. Sebanyak 30 peserta ikut dalam kegiatan ini yang berasal dari Gapoktan, penyuluh dan dari Dinas Perikanan Kab. Bulukumba. Materi penyuluhan yang disampaikan dipahami dengan baik oleh peserta melalui kegiatan diskusi setelah pemaparan materi.
