Abstract

Infeksi penyakit pada karang telah diidentifikasi sebagai salah satu faktor utama yang memperburuk kondisi terumbu karang global. Munculnya penyakit karang dicirikan dengan adanya perubahan warna, kerusakan dari skeleton biota karang, sampai dengan kehilangan jaringannya. Contoh penyakit karang yang tersebar di perairan indo-pasifik adalah black band disease (BBD), White Band Disease (WBD), White Syndromes (WS), Pink Blotch (PB), Ulcerative White Spot (UWS), Red Band Disease (RDB), Yellow Band Disease (YBD). Pulau Gili Labak atau yang lebih dikenal dengan Wisata Gili Labak merupakan salah satu wisata bahari yang terletak di sebuah pulau kecil Madura. Pulau Gili Labak saat ini sudah mulai dikembangkan di Kabupaten Sumenep karena adanya potensi pertumbuhan terumbu karang yang cukup baik. Penelitian ini bertujuan mengidentifikasi penyakit pada terumbu karang, prevalensi penyakit karang, dan life form terumbu karang. Pengambilan data dilakukan dengan metode belt transek di tiga stasiun pengamatan di Pulau Gili Labak. Identifikasi penyakit dilakukan secara deskriptif berdasarkan buku coral dieses handbook dan referensi jurnal. life form yang ditemukan di pulau Gili Labak ada 9 tipe life form. Jenis penyakit  terumbu karang yang ditemukan di Pulau Gili Labak ada 4 jenis penyakit yaitu White Band Disease, Ulcerative White Spot, White Syndrome, dan Pink Line Syndrome. Prevalensi penyakit karang di Pulau Gili Labak dengan nilai rata-rata prevalensi sebesar (1,7%). Coral disease infections have been identified as one of the main factors deteriorating the condition of coral reefs globally. The emergence of coral disease is characterized by changes in color, damage to the skeleton of coral biota, and even loss of their tissues. There are examples of coral diseases that are spread in Indo-Pacific waters are black band disease (BBD), White Band Disease (WBD), White Syndromes (WS), Pink Blotch (PB), Ulcerative White Spot (UWS), Red Band Disease (RDB) , Yellow Band Disease (YBD). Gili Labak Island or better known as Gili Labak Tourism is one of marine tourism site located on the small island of Madura. Gili Labak Island is currently starting to be developed in Sumenep Regency because of the potential for quite good coral reef growth. This research aims to identify diseases on coral reefs, the prevalence of coral diseases, and the life form of coral reefs. Data collection was carried out using the belt transect method at three observation stations on Gili Labak Island. Disease identification was carried out descriptively based on the coral disease handbook and journal references. There are 9 types of life forms found on Gili Labak Island. There are 4 types of coral reef diseases found on Gili Labak Island, called White Band Disease, Ulcerative White Spot, White Syndrome, and Pink Line Syndrome. The prevalence of coral disease on Gili Labak Island with an average prevalence (1.7%).

Abstract

The pond land suitability is the most important things in shrimp farming to maintain production and ensure the development of aquaculture businesses. This research aims to determine the outland suitability of the coastal area of Karangasem Regency, evaluate the distribution pattern of cultivation activities and identify regional development factors. This research was a descriptive qualitative study where the analysis results related to mapping of land uses studies are presented descriptively. The data used in this study consisted of primary data: (i) physical-geographic of coastal areas; (ii) public aspirations in coastal areas, and secondary data traced from BPS, Ministry of ATR/BPN Office of Karangasem and PUPR Service Karangasem Regency. The results of this research showed that the spatial analysis of the land suitability in Kubu sub-district showed the land potential with high suitability is 1,009.46 ha; moderate suitability land level is 1,894.01 ha; for coastal areas that do not have potential or are not feasible for developing shrimp water ponds is 799.67 ha. The Kubu sub-district is a center of the shrimp water ponds development in Karangasem Regency, Bali. The existing condition of shrimp water ponds in Kubu sub-district are spread over 3 villages: Sukadana with 20.36 ha; Tianyar in 1,32 ha and West Tianyar with 0.47 ha in area. Through the analysis of internal and external factors of shrimp pond development activities in Kubu Subdistrict, showed that the coastal area of Kubu Subdistrict is very feasible to develop Vannamei shrimp.

Abstract

Gili Labak is a small island in Sumenep Regency. The area of ​​the island is only ± 5 ha, of which 2.1 ha is a stretch of white sand. The width of the white sand beaches surrounding Gili Labak Island is an average of 20 meters wide, with a coastline of 1,200 meters, providing a wide and comfortable beach tourism area for visitors. The coral reef ecosystem on Gili Labak Island, which is in good condition, covers an area of ​​80.99 ha. This research aims to evaluate the impact of marine tourism activities on coral reef ecosystems. Research was conducted using qualitative and quantitative methods. In this research qualitative methods were used related to tourism activities. The quantitative research method used is a survey method to observe the condition of the coral reef ecosystem on Gili Labak Island, and collect spatial data and attribute data. To determine the impact of tourism on the island of Gili Labak, a questionnaire survey was used to determine the demographics of visitors, their activities on the island. The results of observations of oceanographic conditions obtained in 2019 versus 2023 oceanographic data are not too different. The condition that is very different is the coral cover which tends to decrease. Coral life forms tend to be stable, but there is a decrease in the number of life forms at station 2 which is located on the west side of the island. The results of observations on habitat resilience show that all habitats have high resistance to natural disturbances, but changes in land area and habitat structure easily occur due to human activities, such as marine tourism and fishing boats. Marine tourism activities contribute greater pressure to coral reefs than fishing activities.
