In the state of Melaka, there are eighteen islands recorded by the Melaka State Museum Corporation (PERZIM). Part of this island serves as a tourist island, and developed islands are also uninhabited islands. However, three islands are recorded to have amazing coral reefs that are still in good condition. The Penang Batu Maung Fisheries Research Institute (AkuaTAR) has conducted a study on the biodiversity of coral reefs around the waters of Pulau Dodol, Pulau Serimbun, and Pulau Undan. AkuaTAR researchers are using scuba diving methods, and at the same time, they did conservation on coral reefs that have been identified in the waters of the Straits of Melaka. The objective of this study is to record the types of community forms such as living corals and identify the species of coral reefs found in three islands in the state of Melaka in Pulau Undan, Pulau Dodol, and Pulau Serimbun. The study also implemented method observation by conducting field studies on the islands involved by doing scuba diving. Results and discussion of the search, these three islands are located in very clean, uninhabited waters. They have a wide range of coral biodiversity using soft coral reefs and hard coral reefs. The study also found that the three islands in the state have the largest coral reefs in the waters of the Straits of Melaka. Keywords: Biodiversity; Conservation; Coral; Three island; Melaka

Mapping of the potential of coral reefs on the coast of the Madura Strait is evaluated. The coral mapping purposes are to evaluated a total area of the coral reefs in line with the current condition. The index of the area of coral reefs on the coast of the Madura Strait was also compiled to produce a database of the parameters that affect to the coral reefs growths. The imaga data processed is using Landsat. Maping data processing methos is using Lyzinge Algorithm since the area has shallow water area characteristics. The area of coral reef substrate identified according to the processed image is 10.478.032 Ha. The Landsat 7 satellite imagery has an ability to detect the characteristics of shallow waters using blue channels with wavelengths of 0.45-0.52 µm and green channels with wavelengths of 0.52-0.60 µm. However, to determine the condition and how severe the damage to coral reefs, detection with satellite imagery is not enough so that direct observation is needed through scuba diving activities. Scuba diving is carried out to determine the condition of coral reefs. Roughly, coral reef ecosystems in the objects are categorized as moderate to damaged. The damage to this coral reef ecosystem identified at the depths of 5 and 10 meters. Pemetaan potensi terumbu karang dilakukan di area pesisir Selat Madura. Pemetaan ini dilukan dengan memanfaatkan data citra satelit dari Landsat 7 dan pengolahan data menggunakan metode Algoritma Lyzinge. Studi ini bertujuan untuk mengetahui cakupan luas dari sebaran terumbu karang serta kondisi terumbu karang. Indeks dari area terumbu karang dipetakan dan disusun untuk selanjutkan digunakan sebagai basis data yang berisi tentang informasi yang mengadung parameter – parameter yang berpengaruh terhadap pertumbuhan terumbu karang. Dalam penelitian ini, terumbu karang ditemukan di perairan dangkal yang jernih. Citra satelit Landsat 7 memiliki sensor yang dapat mendeteksi karakteristik perairan dangkal dengan memanfaatkan saluran/ kanal biru dengan panjang gelombang 0,45-0,52 µm dan saluran/ kanal hijau dengan panjang gelombang 0,52-0,60 µm. Namun, untuk mengetahui kondisi dan tingkat kerusakan terumbu karang, pendeteksian dengan citra satelit tidaklah cukup sehingga diperlukan pengamatan secara langsung melalui aktivitas penyelaman scuba. Hasil yang diperoleh dari penelitian ini adalah luas substrat terumbu karang adalah 10,478.032 Ha. Hasil dari scuba diving menunjukkan bahwa secra umum ekosistem terumbu karang di perairan Selat Madura berada dalam kondisi sedang hingga rusak. Kerusakan ekosistem terumbu karang ini terjadi pada kedalaman 5 dan 10 meter.

slas del Rosario and San Bernardo is a National Nature Park that protects coral reefs and mangroves but is increasingly affected by tourism. Between April 2011 and January 2013 we interviewed users of the 16 main submarine trails. The most frequented trail was Ministerio / Acuario mío (23,7 ± 5,7 %); Open Water scuba diving was the main diving certificate among tourists (63,5 ± 4,5 %); 58.6% lacked basic diving experience, and 74% had some type of contact with the corals (mostly hard coral: 0,9 ± 0,05). An average there were 5,39 contacts per diver (scuba). For basic diving there was an average of 0.18 contacts/ min/ diver. Diving causes direct and indirect damages to these ecosystems. Most coral contacts are from inexperienced divers: training the tourists is fundamental.

The aim of this research is to determine the species richness, individual abundance, and the ecology index of the coral fishes on the artificial reef of Kareko waters,  District of North Lembeh - Bitung City. The data is collected using “Visual Census” technique by scuba diving. The amount of the reef fishes found in the artificial coral reefs were 53 species. The abundance species in the artificial reefs which made from metal were 34 species and which made from concrete were 35 species. The total of number individuals of coral fishes from 47 species is 210.50 individuals/30m2. The total density was 7,017 individuals/m2. The highest relative density on iron-made reefs was found in Dascyllus trimaculatus (15.73%) and and which made from concrete were Dascyllus reticulatus (10.85%).  Based on H’, H’max, and H’min, the diversity Index  of coral fishes in both artificial reefs including high.Keywords : Coral Fishes, Artificial Reef, Kareko ABSTRAKTujuan penelitian ini yaitu untuk mengetahui kekayaan spesies, kelimpahan individu, dan indeks ekologi ikan karang pada terumbu buatan di Perairan Kareko.

The species diversity and distribution of demosponges dwelling in the coral reefs, at Had Khanom—Mo Ko Thale Tai National Park on the southern coast of the Gulf of Thailand, was investigated, with field surveys undertaken at 12 sites in November 2006 using SCUBA diving and random observation. Forty-five species of demosponges from 10 orders, 24 families and 34 genera were recorded. The most abundant and common sponges in this area are: Oceanapia sagittaria; Neopetrosia sp. blue; Xestospongia testudinaria; and Haliclona (Gellius) cymaeformis. Most species are common representatives of the Indo-Pacific fauna found throughout the Gulf of Thailand.
