"This article looks at the life of Binongko people. The word "Binongko" is well known as a Buton migrant's identity from Southest Sulawesi in Maluku. In fact, it is a name of a rock island in Wakatobi district. Few people know about this fact. Binongko people built their world through the myth of La Patua Sakti and Putri Bidadari. Since environment did not support farming activities, most of the people's need were supplied by the sea through sailing. This activity was old as their history in this island. The people also developed their skills as blacksmiths, which supported sailing tradition. This profession was an old identy of Wakatobi. This island brought about: early migrants of Buton in Maluku, skilful sailor, and ulamas, who were hard-working people. This study finds the relationship between the environment, history, and culture of Binongko people in Wakatobi area."

"Moradi M, Kamrani E, Shokri MR, Ranjbar MS, Hesni MA (2009) First record of two hard coral species (Faviidae and Siderastreidae) from Qeshm Island (Persian Gulf, Iran). Nusantara Bioscience 2: 34-37. Two species of hard corals including Cyphastrea chalcidicum (Forskal 1775) (Faviidae) and Coscinaraea monile (Forskal 1775) (Siderastreidae) were collected from the south of Qeshm Island (Persian Gulf, Iran) in the late of 2008. These species were previously reported from southern Persian Gulf, Gulf of Aden, Southeast Africa and Indo-Pacific. The literature review on the distribution of these two species revealed that these species were firstly recorded from the Persian Gulf. These findings further emphasize the high diversity of coral fauna in the Iranian waters of the northern Persian Gulf. "

"Keberadaan ekosistem terumbu karang berperan penting secara ekologis karena menjadi sumber kehidupan bagi berbagai biota laut. Penurunan kualitas ekosistem terumbu karang di Indonesia, disebabkan oleh aktivitas manusia dan pengaruh alam. Penelitian dilakukan di empat stasiun Pulau Pramuka, Kepulauan Seribu (Utara, Timur, Selatan, dan Barat). Penelitian ini bertujuan untuk menganalisis kondisi kesehatan terumbu karang dengan mengetahui persentase tutupan dan warna terumbu karang, mengidentifikasi bentuk koloni terumbu karang, serta menganalisis dominansi, keanekaragaman dan keseragaman karang. Metode yang digunakan yaitu metode Underwater Photo Transect (UPT) dan dianalisis menggunakan software CPCe (Coral Point Count with Excel extension), lalu metode CoralWatch (CW) dengan Coral Health Chart, serta perhitungan indeks dominansi (Simpson), keanekaragaman (Shannon-Wiener), dan keseragaman (E). Analisis CPCe menunjukkan bahwa tutupan persentase terumbu karang berada pada kategori sedang (30,87-42,20%). Analisis CoralWatch menunjukkan Stasiun 1, 2, dan 4 mayoritas terumbu karangnya mengalami stres dengan persentase karang sehat masing-masing sebesar 29,36%, 9,23%, dan 15,22%, sedangkan Stasiun 3 memiliki proporsi karang sehat lebih tinggi (35.65%).  Ditemukan 10 bentuk koloni karang, Coral Massive mendominasi di Stasiun 1 (50), Stasiun 2 (69), dan Stasiun 3 (19). Stasiun 4 di dominasi oleh Coral Foliose (34). Hasil analisis indeks biodiversitas terumbu karang berada pada kategori dominansi rendah (0,25), keanekaragaman sedang (2,47), dan keseragaman rendah (0,36).

The existence of coral reef ecosystems plays an important role ecologically because it is a source of life for various marine biota. The quality of coral reef ecosystems in Indonesia can decline, due to human activities and natural influences. The research was conducted at four stations on Pramuka Island, Seribu Islands (North, East, South and West). This research aims to analyze the health condition of coral reefs by knowing the percentage of coral cover and color, identifying the shape of coral reef lifeform, and analyzing coral dominance, diversity and uniformity. The method used is method Underwater Photo Transect (UPT) and analyzed using CPCe software (Coral Point Count with Excel extension), method CoralWatch (CW) with Coral Health Chart, as well as calculation of dominance (Simpson), diversity (Shannon-Wiener) and uniformity (E) indices. CPCe analysis shows that the percentage cover of coral reefs is in the medium category (30.87-42.20%). CoralWatch analysis shows that Stations 1, 2, and 4 have the majority of coral reefs experiencing stress with healthy coral percentages of 29.36%, 9.23%, and 15.22%, respectively, while Station 3 has a higher proportion of healthy corals (35.65%). About 10 lifeform were found, Coral Massive are dominating at Station 1 (50), Station 2 (69), and Station 3 (19). Station 4 is dominated by Coral Foliose (34). The results of the coral reef biodiversity index analysis are in the categories of low dominance (0,25), medium diversity (2.47), and low uniformity (0.36)."

"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."

"Kepulauan Seribu dikenal sebagai sektor pariwisata, terutama wisata bahari dan memiliki kondisi oseanografi yang optimal untuk kesesuaian terumbu karang. Taman Nasional Kepulauan Seribu (TNKS) adalah kawasan sebagai bentuk upaya konservasi ekosistem terumbu karang dan spesies lainnya, dengan beberapa zonasi pemanfaatan kawasan di dalamnya. Pemanfaatan setiap zonasi di TNKS mempengaruhi kondisi lingkungan di darat dan di laut, termasuk terumbu karang. Setiap zona memiliki masalah atau tekanan yang berbeda baik dari faktor alam atau aktivitas manusia. Tujuan dari penelitian ini adalah untuk menganalisis distribusi terumbu karang dan perbedaan yang terkait dengan karakteristik fisik perairan di setiap zonasi di Taman Nasional Kepulauan Seribu. Distribusi terumbu karang diperoleh dengan menggunakan metode Koreksi Kolom Air yang diproses menggunakan citra Sentinel-2A. Setelah itu, pengolahan data variabel penelitian dilakukan dengan menggunakan batimetri, suhu, arus laut dan data kecerahan laut. Analisis deskriptif spasial digunakan dalam penelitian ini untuk menjelaskan pola distribusi terumbu karang di zona TNKS. Dalam penelitian ini ditemukan bahwa pola penyebaran terumbu karang di Pulau Belanda berpusat di Timur Laut sedangkan di Pulau Bira Besar dan Pulau Pramuka tersebar merata di sepanjang rataan terumbu. Persentase tertinggi dari distribusi terumbu karang ditemukan di zona inti & perlindungan, yang setara dengan 6% dari semua wilayah habitat bentik di pulau penelitian. Selain itu, inter-zoning memiliki karakteristik kecerahan dan kedalaman yang bervariasi sesuai dengan lokasi geografi.

The Thousand Islands is known as the tourism sector, especially marine tourism and has optimal oceanographic conditions for the suitability of coral reefs. Thousand Islands National Park (TNKS) is an area as a form of conservation efforts for coral reef ecosystems and other species, with some zoning utilization of the area in it. The use of each zoning in KSNP affects the environmental conditions on land and at sea, including coral reefs. Each zone has a problem or pressure that is different from either natural factors or human activities. The purpose of this study was to analyze the distribution of coral reefs and differences related to the physical characteristics of the waters in each zoning in the Thousand Islands National Park. The distribution of coral reefs was obtained by using the Water Column Correction method which was processed using Sentinel-2A imagery. After that, the processing of research variable data is carried out using bathymetry, temperature, ocean currents and sea brightness data. Spatial descriptive analysis was used in this study to explain the distribution pattern of coral reefs in the TNKS zone. In this study it was found that the distribution pattern of coral reefs on the Dutch Island was centered in the Northeast while in Bira Besar Island and Pramuka Island were spread evenly along the reef flats. The highest percentage of coral reef distribution is found in the core & protection zones, which is equivalent to 6% of all benthic habitat areas on the research island. In addition, inter-zoning has brightness and depth characteristics that vary according to geographical location."
