"This book provides for the first time a complete review of both the geology and biology of all extant coral areas in the Gulf, the water body between Iran and the Arabian Peninsula. In summer, this area is the hottest sea with abundant coral growth on earth and already today exhibits a temperature that is predicted to occur across the topical ocean in 2100. Thus, by studying the Gulf today, much can be learned about tomorrow’s world and the capability of coral reefs to adapt to climatic extremes. This volume provides the most authoritative and up-to-date review of the coral reefs in the Gulf. It can be used as a volume of general reference or as a textbook treating recent coral reefs."

"Terumbu karang merupakan salah satu potensi sumberdaya laut yang sangat penting di Indonesia. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh karakteristik fisik perairan terhadap persebaran terumbu karang di Wilayah Perairan Karawang pada tahun 2001, 2010 dan 2017. Metode yang digunakan adalah survei lapang dan pengolahan data citra menggunakan algoritma Lyzenga untuk mengetahui persebaran terumbu karang di Wilayah Perairan Karawang. Hasil penelitian menunjukan terumbu karang di Wilayah Perairan Karawang tersebar di 3 Pantai, yaitu Pantai Ciparage, Pantai Desa Pasirjaya dan Pantai Desa Sukajaya. Terumbu karang tersebar dengan pola mengelompok. Adapun jenis terumbu karang yang ada di wilayah penelitian adalah gugusan karang gosong patch reefs. Pola pertumbuhan terumbu karang di wilayah penelitian ini memiliki pola semakin jauh dari daratan maka perubahan luas terumbu karang akan semakin bervariasi. Karakteristik fisik perairan pada penelitian ini yaitu suhu permukaan laut, salinitas dan arus di wilayah perairan Karawang pada penelitian ini sudah sesuai dengan baku mutu perairan untuk terumbu karang, sehingga terumbu karang dapat tumbuh dan berkembang. Adapun pengaruh dari karakteristik fisik perairan ini mempengaruhi persebaran terumbu karang dalam jangka waktu lama yang dalam penelitian ini adalah tahun 2001-2017, karena ketika karakteristik fisik perairan tidak sesuai dengan baku mutu, terumbu karang tidak langsung mati tetapi akan mengalami berbagai proses hingga akhirnya mati. Adapun ketika suhu permukaan laut tidak sesuai dengan baku mutu, terumbu karang akan mati, sedangkan pada salinitas tinggi diluar nilai ambang batas baku mutu, terumbu karang tidak dapat tumbuh dan berkembang. Pada arus permukaan laut, terumbu karang hidup cenderung memiliki pola yang searah dengan rata-rata arah arus laut dalam waktu setahun.

Coral reefs are one of the most important marine resource potentials in Indonesia. The purpose of this research is to analyze the influence of physical characteristics of waters on the distribution of coral reefs in the Waters of Karawang region in 2001, 2010 and 2017. The method used is field survey and image data processing using the Lyzenga algorithm to determine the distribution of coral reefs in the Waters of Karawang.

The results showed coral reefs in the Waters of Karawang spread in 3 Beaches, namely Ciparage Beach, Beach Village Pasirjaya and Beach Village Sukajaya. Coral reefs are scattered with clumping patterns. The type of coral reefs that exist in the research area is a cluster of charred rubbers patch reefs.

The pattern of coral reef growth in this study area has a pattern farther from the land, the changes in coral reefs will be more varied. Physical characteristics of the waters in this study are sea surface temperature, salinity and current in the waters of Karawang in this study is in accordance with the standards of water quality for coral reefs, so that coral reefs can grow and develop.

The influence of physical characteristics of this water affect the distribution of coral reefs in the long term which in this study is the year 2001 2017, because when the physical characteristics of the waters are not in accordance with the standard of quality, coral reefs do not die immediately but will experience various processes until finally die. As the sea surface temperature does not conform to the quality standard, coral reefs will die, while at high salinity beyond the standard quality threshold values, coral reefs can not grow and develop. At sea level currents, living coral reefs tend to have a unidirectional pattern with an average direction of ocean currents within a year."

"ABSTRACTBangka Island is well known as the world's largest tin producer. The inland and offshore tin mining has profound effects on the coastal environment, resulting in the high sedimentation in the water. Many corals suffered physiological damage due to low light intensity. The distribution of stony corals and the status of coral reefs was surveyed at 6 sites in West Bangka waters in October 2012. A total of 72 species of corals belonging to 33 genera and 12 families were found, and 4 species were distributed at all research sites. The live coral coverage was 36% on average and was categorized as being in fair condition. The coverage was 0% at Kamboja Island where the corals were the most affected by tin mining. The sediment flowed out from tin mining, blocked the light, and settled on the coral's surface. Consequently, many corals were buried and the live corals decreased. It is obviously necessary to reduce and control the tin mining."

"Terumbu karang merupakan ekosistem yang kompleks dengan keragaman biologi tinggi yang mendukung produktivitas perikanan. Belum banyak penelitian mengenai informasi data bio-bisik, sosio-ekonomi, dan tata kelola dalam pengelolaan kawasan konservasi di Pangandaran Kabupaten Ciamis. Penelitian ini dilakukan untuk menganalisis kondisi terumbu karang dari aspek bio-fisik, sosio-ekonomi, dan tata kelola sejak penetapan pencadangan sebagai kawasan konservasi laut serta faktor-faktor yang mempengaruhi. Pengumpulan data kondisi biofisik terumbu karang dilakukan dengan metode transek garis (line intercept transect/LIT) pada lokasi Pasir Putih, Batu Mandi, Batu Layar, dan Batu Nunggal di 8 titik kedalaman (3 m dan 5 m). Kondisi lingkungan terumbu karang dilakukan dengan pengukuran parameter-parameter kualitas perairan (suhu, kecerahan, salinitas, arus, dan pH). Untuk mengetahui kondisi sosial ekonomi masyarakat dan tata kelola dilakukan dengan menggunakan kuisioner dan wawancara dengan 57 orang responden. Data sekunder kondisi terumbu karang sebelum dan sesudah penetapan kawasan konservasi laut di Pangandaran dikumpulkan dari hasil penelitian-penelitian sebelumnya.Indikator biofisik menunjukkan hasil trend tutupan karang hidup di kedalaman 3 m mempunyai kecenderungan menurun, dan kedalaman 5 m mempunyai kecenderungan tutupan karang hidup yang stabil. Kondisi terumbu karang di lokasi penelitian berada pada status buruk sampai dengan baik. Kondisi terumbu karang di Pangandaran dipengaruhi oleh aktivitas pariwisata dan aktivitas penangkapan ikan, serta peran aktif masyarakat dalam pengelolaannya. Pengelolaan kolaboratif kawasan konservasi terumbu karang di Pangandaran Kabupaten Ciamis merupakan faktor penentu kelestarian terumbu karang.

Coral reefs are complex ecosystems with high biodiversity that supports the productivity of fisheries. Not much information on the research of bio-physical, socio-economic, and governance in the management of conservation areas in Pangandaran Ciamis. The research was carried out to analyze the condition of coral reefs in the aspects of bio-physical, socio-economic, and governance since the establishment of marine reserves as a conservation area and the factors that influence. Biophysical condition of coral reefs conducted by the line intercept transect (LIT) at the location of Pasir Putih, Batu Mandi, Batu Layar, and Batu Nunggal in 8 point depths (3 m and 5 m).

The environmental conditions of coral reefs conducted by measuring the water quality parameters (temperature, brightness, salinity, currents, and pH). To find out the socio-economic conditions of society and governance is done by using a questionnaire and interviews with 57 respondents. Secondary data coral reefs before and after the establishment of marine protected areas in Pangandaran collected from the results of previous studies.

Biophysical indicator shows trend results live coral cover in depth of 3 m have a tendency to decline, and a depth of 5 m has a tendency to live coral cover was stable. The condition of coral reefs in the study sites are in poor to good status. The condition of coral reefs in Pangandaran is influenced by the activity of tourism and fishing activities, as well as the active role in its management. Collaborative management of coral reef conservation in Pangandaran Ciamis is an important determinant of coral reef conservation."

"ABSTRACTProviding accurate information on suitable multispectral satellite sensors for mapping coral reefs in Indonesia is a challenge for coastal remote-sensing experts. As coral reefs vary in spatial extent, shape, length, perimeter and/or distance to shore, the mapping of coral reefs will need different satellite sensors depending on the objectives and the kind of information required. This work compares the suitability of two kinds of multispectral satellite sensors for mapping coral reefs in Indonesia, high and moderate spatial resolution. This was done through a case study of Wakatobi Marine National Park since that represents many types of coral reef in Indonesia (fringing, barrier, atoll, and patch). Indonesian coral reef shapefile data 2010 was downloaded from UNEP (United Nations Environment Programme) website, and Landsat 7 ETM + images, path/row 112/064 was used to determine the terrestrial area of Wakatobi Islands. Both high and moderate spatial resolution sensors are suitable for mapping the benthic communities and geomorphic zones on coral reefs. The former are more accurate but they are also much less cost-effective, especially over large areas."

"Indonesia berada di segitiga terumbu karang dengan populasi terbesar di dunia. Indonesia memiliki hamparan ekosistem terumbu karang seluas 2,5 juta hektar yang di dalamnya terdapat 362 spesies hard coral dengan 66 spesies di antaranya merupakan jenis ekonomi penting. Kurun 2012-2016 Indonesia berkontribusi rata-rata sebesar 5,58 % sebagai eksportir karang hias terbesar kedua dunia setelah Jepang. Pemanfaatan karang untuk perdagangan turut memicu isu kerusakan habitat, perdagangan ilegal, serta gangguan kesehatan karang sehingga mendorong pemerintah untuk merumuskan regulasi pemanfaatan terumbu karang untuk perdagangan melalui kebijakan kuota pengambilan karang dari alam dan larangan ekspor karang hias dengan tujuan dapat memperbaiki kondisi terumbu karang di Indonesia. Studi ini bertujuan untuk menemukan bukti empiris apakah kebijakan tersebut di atas dapat mempengaruhi kondisi terumbu karang di Indonesia. Penulis menggunakan Fixed-Effect Model pada persamaan regresi Difference in Difference menunjukkan hasil bahwa tidak terdapat perbedaan nyata kondisi terumbu karang di Indonesia selama penerapan kebijakan kuota pengambilan karang dari alam serta antara sebelum dan setelah adanya kebijakan larangan ekspor karang hias. Hal ini menunjukkan bahwa larangan ekspor karang hias tidak mempengaruhi secara signifikan terhadap kondisi terumbu karang di Indonesia.

Indonesia is in the coral triangle with the largest coral population in the world. Indonesia has a coral reefs covering an area of 2,5 million hectares in which there are 362 species of hard coral with 66 species being economically important species. In the period between 2012-2016, Indonesia contributed an average of 5,58 % as the world’s second largest ornamental corals exporter after Japan. The utilization of coral for trade also sparked the issues of habitat destruction, illegal trade, and coral health problems has prompted the government to formulate regulations on the utilization of coral reefs for trade through a quota policy for taking coral from nature and the export banning of ornamental coral with the aim of improving the condition of coral reefs in Indonesia. This study aims to find an empirical evidence does the policies mentioned above affect the condition of coral reefs in Indonesia. The author uses the Fixed-Effect Model on the Difference in Difference regression equation whose result show that there were no real differences in the condition of coral reefs in Indonesia during the implementation of the quota policy for taking coral from nature and between before and after the export banning of ornamental coral. This shows that export banning of ornamental corals does not significantly affect the condition of coral reefs in Indonesia."

"During three months period observations (November 16 to January 13, 2001) in coral reefs of Pramuka IslandIndonesia, the nudibranch Phyllidia varicosa was observed while feeding on the sponge Axinyssa cf. aculeata. Duringfeeding, P. varicosa extended externally the pharyngeal bulb onto the sponge causing visible somatic damage. Thebehaviors of contracting the body and retracting the rhinopores inside the rhinotube were also observed while feeding.Observations on the feeding of Phyllidia varicosa on the sponge Axinyssa cf. aculeata and the presence of a visiblesomatic damage on the prey due to predation are reported for the first time."
