Abstract

Semi Refined Carrageenan (SRC) product is considerably cheaper and easy to produce as a natural polysaccharide hydrophilic in food and other product. The aim of this research was  to evaluate  the quality of two different SCR products come from different  coastal waters  of seaweed culture. The products  were then compared  to commercial SCR on the quality based on their  chemical  quality (Fourier Transform Infra Red, sulphate content and heavy metals) and physical quality  (gel strength and viscosity). The method of FTIR was useful as a quality screening for commercially seaweed culture at different geografic places based on their chemical structure. Raw material that have been used for SCR product  was  Eucheuma cottonii with k-carrageenan type. FTIR spectroscopy showed the molecular present in three different samples are quite similar, it can be found spectra band of 1257,59 cm-1 which referred to esther sulphate, 933,55 cm-1 for 3,6 anhydrogalactose and 848,68 cm-1 assigned to  galactosa-4- sulphate respectively. The SCR product from  different coastal waters were different on their quality.

Abstract

Coral reefs are known as complex marine ecosystems. They play essential role in sustaining life. These ecosystems can serve as conservation areas as well as marine tourism object. The condition of coral reef degradation in Indonesia is quite worrying. One contributing factor is increasing heavy metal pollution in the waters. Levels of heavy metals that exceed the quality standard are very harmful to coral reefs. Heavy metals can not be degraded in waters but can be absorbed. Considering the importance of coral reef ecosystems and the increasing number of heavy metal pollution, it is necessary to know the effect of heavy metals on Corals. In general, the effect of heavy metals on corals can be divided into two, effects that did not cause of death (sublethal) and cause of death (lethal).

Abstract

Ribbonfish as demersal fish which is one of export commodity and can be found in Java coasts and estuaries in Sumatra. This research aims to determine the food habits of ribbonfish (Trichiurus lepturus) by analyzing the types of food found in the stomach of the fish collected from coastal area of Bandengan, Jepara Regency and the waters of Tawang, Kendal, both in Central Java Province. Food habits of fish was determined by stomach content analysis. The result indicates that food type of ribbonfish (T. lepturus) from Bandengan, Jepara, mostly were anchovies, long-jawed mackarel and white snappers. While food type of fish from Tawang, Kendal, mostly were ponyfish, followed by longjawed mackarel, and anchovies. The difference of food habits probably due to biotic condition environmental differences and like temperature, light, space and surface area.

Abstract

Human activities in the Karimunjawa National Park increase water pollution, including heavy metals such as lead (Pb) and copper (Cu). The existence of heavy metals in sea waters can not be degraded, but it can be absorbed and accumulated in the body of organisms, including coral, Pocillopora damicornis. Given the existence of coral P. damicornis as sessile organism which are able to absorb lead (Pb) and copper (Cu) from the water, therefore, it is necessary to conduct research on heavy metals content in the coral. The purpose of this study was to determine the content of heavy metals lead (Pb) and copper (Cu) on the coral P. damicornis taken from several locations around the Karimunjawa National Park. The results of the study showed that heavy metals content in the water was not detected. While the highest Pb and Cu were found in the coral collected from Burung Island that was equal to 0.00405 ppm and 0.01121 ppm, respectively. The lowest Pb substance were found in the coral collected from Kemojan canal i.e. 0.00143 ppm. Sample collected from Indonoor, Kemojan canal and Karimunjawa port did not contain Cu substance. Based on Pb and Cu data contained in the coral and water samples Minister of Environment Decree No.51st, 2004, it could be concluded that the conditions of Karimunjawa National Park was still in the stage of no contamination.

Abstract

Kima, yang merupakan salah satu hewan laut dilindungi, sejak lama banyak dieksploitasi di berbagai daerah di Indonesia. Apabila keadaan ini terus berlanjut maka akan terjadi penurunan populasi di alam yang berujung pada kepunahan dari berbagai spesies Kima tersebut di alam. Penelitian ini bertujuan untuk menganalisis kelimpahan Kima di beberapa pulau di Kepulauan Seribu dan perairan di sekitar Manado. Metode penelitian yang digunakan adalah deskriptif yang bersifat eksploratif. Sampling dilakukan dengan metode Line Intersept Transect (LIT) menggunakan garis transek sepanjang 100 meter sejajar dengan garis pantai pada kedalaman 5 meter. Pengamatan dilakukan pada tiap 2,5 meter di sebelah kanan dan kiri garis transek. Hasil penelitian, ditemukan total 167 individu Kima di Kepulauan seribu dan 61 individu di perairan Manado.  Nilai kepadatan rata - rata pada lokasi Kep. Seribu adalah T. squamosa 0.026 indv/m2, T. maxima 0,016 indv/m2, T. crocea 0.028 indv/m2 sedangkan pada lokasi Manado adalah T. squamosa 0.021 indv/m2, T. maxima 0.0005 indv/m2, T. crocea 0.0085 indv/m2 dan T. gigas 0.002 indv/ m2. Hasil ini menunjukkan bahwa kepadatan Kima di dua lokasi penelitian masih lebih rendah dari beberapa lokasi di Indonesia dan luar negeri. Berdasarkan ukuran cangkang di dua lokasi penelitian diduga hanya T. crocea saja yang telah mencapai fase hermafroditiknya, sedangkan T. gigas dan sebagian besar T. squamosa serta T. maxima baru mencapai fase kematangan gonad jantan saja. Kebanyakan Kima ditemukan di  karang mati beralga (Dead Coral Algae / DCA) dan tututan karang hidup (coral covered) dibandingkan dengan jenis substrat yang lain. Kata kunci : Kima, tridacna, kelimpahan, Kepulauan Seribu, Manado   Giant clam, as a protected marine species, has been exploited massively in many regions in Indonesia. This has lead to the rapid extinction of the giant clam natural population. The purpose of the research is to obtain the abundance status of giant clam species in several island in Kepulauan Seribu and surroundings waters of Manado. Surveys were done by using the modification of Line Intercept Transect (LIT) methods. A hundred meter length of transect line were drawn, in depth of 5 meter and paralleled to the coast line. The observations were made in 2.5 meter to the left and right of the transect line. The results showed, there were total number of clams found at Seribu Islands and Manado waters were 106 and 61 individual, respectively. The average density in Seribu Islands were T. squamosa: 0.026 indv/m2, T. maxima: 0.016 indv/m2, and T. crocea: 0.028 indv/m2, and in Manado were T. squamosa: 0.021 indv/m2, T. maxima: 0.0005 indv/m2, T. crocea: 0.0085 indv/m2 and T. gigas: 0.002 indv/m2. These results showed that the density of giant clams in both places were  found to be lower than other places in Indonesia and abroad. Based from the shell measurements on both locations, only T. crocea were suspected have reached its hermaphrodite phase, while T. gigas and most of T. squamosa and T. maxima were about to reached male gonad maturity phase. The most dominant substrate for the giant clam were the Dead Coral Algae (DCA) and the coral covered. Key  words: Giant clam, tridacna, abundance, Seribu Islands, Manado
