Abstract

Terumbu karang memiliki fungsi ekologi penting sebagai pelindung fisik dari gelombang, tempat pemijahan dan asuhan, serta sebagai penyedia makanan bagi biota laut. Namun, kondisi ekosistem terumbu karang tidak terlepas dari ancaman-ancaman baik dari faktor biotik maupun abiotik. Aktivitas wisata seperti penyelaman dan adanya buangan limbah dari wisatawan dapat dimungkinkan mengganggu kesehatan dan kestabilan ekosistem terumbu karang. Selain itu, buangan limbah dan sisa pakan dari kegiatan budidaya ikan juga dapat mengganggu kesehatan dari terumbu karang. Sehingga, tujuan dari penelitian ini yaitu untuk mengetahui jenis dan prevalensi penyakit yang teridentifikasi pada karang famili Acroporidae di kawasan wisata dan non-wisata (permukiman dan budidaya perikanan) di Pasir Putih Situbondo dan sekitarnya. Metode yang digunakan dalam penelitian ini adalah belt transect sepanjang 30 m dan lebar 2 m di kedalaman yang mewakili perairan dangkal (<5 m) dan perairan yang lebih dalam (8-10 m) di 3 lokasi yaitu Batu Lawang (representasi kawasan wisata), pesisir Kembangsambi (representasi kawasan permukiman dan tambak udang), dan Keramba Jaring Apung (representasi kawasan budidaya ikan kerapu) dengan 3 kali replikasi. Pada setiap koloni karang dari famili Acroporidae yang ditemukan, dilakukan pengamatan untuk mengetahui ada tidaknya infeksi penyakit, kemudian mengidentifikasi jenis penyakit karang. Hasil dari penelitian ini yaitu terdapat 11 spesies karang famili Acroporidae yaitu A. brueggemanni, A. divaricata, A. florida, A. gemmifera, A. grandis, A. granulosa, A. loripes, A. millepora, A. muricata, A. nobilis, dan A. palifera yang menjadi spesies paling rentan terinfeksi penyakit karang. Kemudian penyakit karang yang ditemukan diantaranya Black Band Disease (BBD), Red Band Disease (RBD), White Patch Disease (WPD), White Band Disease (WBD), White Plague (WP), Yellow Band Disease (YBD), Pigmentation Response (PR), White Spot Disease (WSD), dan White Syndrome (WS). Prevalensi penyakit karang di Batu Lawang (10 m) memiliki nilai paling tinggi diantara lokasi lainnya, yaitu sebesar 90,02%. Kemudian diikuti oleh KJA (5 m) sebesar 83,33%; Kembangsambi (10 m) sebesar 74,07%; KJA (10 m) sebesar 71,28%; Kembangsambi (5 m) sebesar 63,33%; dan yang paling rendah berada di lokasi Batu Lawang (5 m) yaitu sebesar 31,27%.

Coral reefs have an important ecological function as physical protection from waves, spawning and nurturing sites, as well as providing food for marine biota. However, the condition of the coral reef ecosystem is inseparable from threats from both biotic and abiotic factors. Tourism activities such as healing and the disposal of waste from tourists can potentially disrupt the health and stability of coral reef ecosystems. In addition, waste disposal and leftover feed from fish farming activities can also disrupt the health of coral reefs. Therefore, the purpose of this study was to determine the type and prevalence of identified diseases in corals of the Acroporidae family in tourist and non-tourist areas (settlements and aquaculture) in Pasir Putih Situbondo and its surroundings. The method used in this study was a belt transect with a length of 30 m and a width of 2 m at a depth representing shallow waters (<5 m) and deeper waters (8-10 m) in 3 locations namely Batu Lawang (representation of tourist areas), the Kembangsambi coast (representation of monasteries and shrimp ponds), and Floating Net Cages (representation of grouper cultivation areas) with 3 replications. In each coral colony from the Acroporidae family that was found, observations were made to determine the absence of disease infection, then identification of the type of coral disease was carried out. The results of this study were that there were 11 species of coral in the Acroporidae family, namely A. brueggemanni, A. divaricata, A. florida, A. gemmifera, A. grandis, A. granulosa, A. loripes, A. millepora, A. muricata, A. nobilis, and A. palifera which are the species most susceptible to coral disease. Then the coral diseases found included Black Band Disease (BBD), Red Band Disease (RBD), White Patch Disease (WPD), White Band Disease (WBD), White Plague (WP), Yellow Band Disease (YBD), Pigmentation Response (PR), White Spot Disease (WSD), and White Syndrome (WS). The prevalence of coral disease in Batu Lawang (10 m) has the highest value among other locations, which is 90.02%. Then followed by KJA (5 m) of 83.33%; Kembangambi (10 m) of 74.07%; KJA (10 m) of 71.28%; Kembangambi (5 m) of 63.33%; and the lowest was in the Batu Lawang (5 m) which was 31.27%.
