Abstract

Luas terumbu karang di Indonesia sekitar 85.707 km2 dan mencakup 18% dari total luasan terumbu karang di dunia. Terumbu karang merupakan komponen penting ekosistem laut, karena merupakan sumber kehidupan bagi berbagai biota laut khususnya yang memiliki nilai ekonomis penting. Terumbu karang mempertahankan nilai dan kepentingan dari aspek sosialbudaya, ekologi, dan ekonomi. Pada pesisir Situbondo, gugusan terumbu karang yang tampaknya paling dikenal adalah di kawasan sekitar pantai Pasir Putih. Pada kawasan tersebut juga terdapat berbagai fasilitas pendukung industri pariwisata, termasuk hotel, homestay dan cottage. Tidak jauh dari area wisata juga terdapat permukiman serta industri perikanan dalam bentuk tambak udang (Dusun Kembangsambi) dan budidaya ikan kerapu dengan teknik Keramba Jaring Apung (KJA). Aktivitas-aktivitas tersebut berpotensi berdampak pada kualitas perairan dan terumbu karang yang ada. Keberadaan aktivitas wisata dan fasilitas pendukungnya tersebut juga diperkirakan dapat memberikan dampak negatif lain. Pengambilan data prevalensi dilakukan dengan menggunakan metode Belt Transect dengan panjang transek 30 m. Adapun variabel fisik kimia perairan yang diamati meliputi suhu, salinitas, kecerahan, pH, arus, DO (Dissolved Oxygen), uji kandungan nutrient, dan laju sedimen. Hasil prevalensi menunjukkan tingkat serangan penyakit sebesar 100%, di semua lokasi dan pada dua kedalaman atau semua koloni karang dari famili Poritidae di lokasi pengamatan terinfeksi penyakit, spesies yang ditemukan antara lain P. lobata dan P. lutea dengan koloni massive, serta P. cylindrica dengan koloni branching. Ditemukan jumlah penyakit karang yang paling sering muncul pada semua lokasi dan menginfeksi karang, antara White Spot Disease (WSD), Pigmentation Response (PR), White Patch Disease (WPD), dan Black Band Disease (BBD). Hasil perhitungan jumlah penyakit karang yang menginfeksi genus Porites tertinggi ditemukan pada lokasi Kembangsambi dengan kedalaman 10 m sebanyak 1.136 dari 71 koloni, kemudian diikuti Keramba Jaring Apung dengan kedalaman 10 m sebanyak 1.120 dari 94 koloni dan Batu Lawang dengan kedalaman 10 m sebanyak 669 dari 98 koloni. Pada lokasi Batu Lawang dengan kedalaman 5 m sebanyak 370 dari 35 koloni, lalu diikuti pada Kembangsambi dengan kedalaman 5 m sebanyak 214 dari 17 koloni, kemudian yang terendah ada pada lokasi KJA dengan kedalaman 5 m sebanyak 197 dari 21 koloni.

The area of coral reefs in Indonesia is around 85,707 km2 and covers 18% of the total area of coral reefs in the world. Coral reefs are an important component of marine ecosystems, because they are a source of life for various marine biota, especially those that have important economic value. Coral reefs maintain value and importance from socio-cultural, ecological and economic aspects. On the coast of Situbondo, the cluster of coral reefs that seems to be the best known is in the area around Pasir Putih beach. In this area there are also various supporting facilities for the tourism industry, including hotels, homestays and cottages. Not far from the tourist area there are also settlements and the fishing industry in the form of shrimp ponds (Kembangsambi Hamlet) and grouper fish farming using the Floating Net Cages (KJA) technique. These activities have the potential to impact the quality of existing waters and coral reefs. The existence of tourism activities and their supporting facilities is also expected to have other negative impacts. Prevalence data collection was carried out using the Belt Transect method with a transect length of 30 m. The physical and chemical variables of the waters observed included temperature, salinity, brightness, pH, current, DO (Dissolved Oxygen), nutrient content test, and sediment rate. Prevalence results showed a disease attack rate of 100%, in all locations and at two depths or all coral colonies from the Poritidae family at observation sites were infected with the disease, the species found included P. lobata and P. lutea with massive colonies, as well as P. cylindrica with branching colonies. It was found that the number of coral diseases that occur most often in all locations and infect corals, including White Spot Disease (WSD), Pigmentation Response (PR), White Patch Disease (WPD), and Black Band Disease (BBD). The results of calculating the highest number of coral diseases that infect the genus Porites were found at the Kembangsambi location with a depth of 10 m totaling 1,136 of 71 colonies, followed by KJA with a depth of 10 m with 1,120 of 94 colonies and Batu Lawang with a depth of 10 m with 669 of 98 colonies. At the Batu Lawang location with a depth of 5 m there were 370 of 35 colonies, followed by Kembangsambi with a depth of 5 m with 214 of 17 colonies, then the lowest was in the KJA location with a depth of 5 m with 197 of 21 colonies.
