OSEANA adalah jurnal elektronik nasional yang menerbitkan artikel ilmiah yang bersumber dari penelitian maupun artikel penelaahan pustaka dalam bidang oseanografi di Indonesia. Tujuan dari penerbitan OSEANA adalah untuk memberikan informasi kepada masyarakat yang berminat terhadap bidang oseanologi yang meliputi kegiatan, perkembangan, serta hasil-hasil yang telah dicapai oleh Pemerintah Indonesia khususnya di bidang kelautan. Penerbitan jurnal ini dikelola oleh Pusat Penelitian Oseanografi LIPI dan diterbitkan dua kali setahun di bulan April dan Oktober. Redaksi menerima sumbangan karya yang behubungan dengan ilmu kelautan (oseanografi biologi, oseanografi fisika, oseanografi kimia, oseanografi geologi, dan bidang-bidang terkait lainnya) yang bersifat ilmiah. Redaksi juga menerima tulisan dari ahli/penulis dari luar Pusat Penelitian Oseanografi LIPI.

Abstract

PAH ADSORPTION BY ACTIVATED CARBON. The growing population and the rapid economic development have led an increasing input of waste waters mainly from industries, agriculture and households into marine environment. In addition, discharge of maritime transportation and accidents of oil spills contribute to the marine as pollutants. The released compounds have dangerious effects, for example hazard to human health, hindrance to marine activities, and impairment of the quality of seawaters. Because of hydrophobic character, these compound contaminants tend to be adsorbed to sediment particles and therefore it could be considered as pollution reservoirs. They are also accumulated in the aquatic organisms and biomagnified in the food chains. Some contaminants pose a health risk to aquatic organisms and ultimately to humans who consume contaminated seafood. Therefore, study of activated carbon adsorption will reduce organic pollution such as PAH in marine environment.

Abstract

CULTURE INDEPENDENT APPROACH FOR BACTERIAL COMMUNITY ANALYSIS. Analysis of bacterial community can be through two approaches, through cultivation (culture dependent) and without cultivation (culture independent). Culture dependent approach is conventional method which only covered few bacteria because not all bacteria could be cultured. Culture independent approach with molecular techniques based on DNA communities can provide more information about the structure and diversity of bacteria in nature, both culturable bacteria and unculturable bacteria. 16S rRNA gene is commonly target gene used in bacterial communities analysis. Other specific target genes also being developed for specific groups of bacteria. Several methods are developed for the analysis of molecular markers 16S rRNA or other specific genes, including Denaturing Gradient Gel Electrophoresis (DGGE), Terminal Restriction Fragment Length Polymorphism (TRFLP), and Single Strand Conformation Polymorphism (SSCP).

Abstract

DEVELOPMENT, PRODUCTION, AND THE ROLE OF MARINE MICROALGA IN INDUSTRY. Microalgae cultures recently have been used for various purposes. Culture development of microalgae started from the late 1800s and still continue until now. Specific media composition, lighting, aeration, culture system were applied to many different species microalgae for specific purposes such as pharmaceutical, healthcare, cosmetics, environmental management, energy production, and aquaculture.

Abstract

DEVELOPMENT of Nitzschia sp. AS SEDIMENT TEST ORGANISM. Sediment bioassay requires a test organism which suitable with the test material, for example sediment. However, benthic phytoplankton as the test organism has not been widely applied in Indonesia. Recently, bioassay test still uses phytoplankton which lives in water column such as Chaetoceros gracilis, Tetraselmis sp., Isochrysis sp., or uses another test organism like mussel, sea urchin larvae and amphipod. In addition, Nitszchia sp. is one of culture collection at Research Centre for Oceanography so it could be added value of culture collection. Therefore, this paper aims to describe the potential use of phytoplankton benthic, Nitzschia sp. as sediment test organism.

Abstract

NITROGEN TRANSFORMATION IN MARINE ENVIRONMENT. Nitrogen transformations are undertaken by marine organisms as part of their metabolisms, either to obtain nitrogen to synthesize structural components or to gain energy for their growth. Nitrogen can stimulate primer productivity in an aquatic ecosystem. Increasing human activities can cause the increase of the number of nitrogen in the ocean. The increased input of nitrogen which is often accompanied by oxygen limitation has a strong negative effect on benthic metabolism and nitrogen mineralization. The ocean’s nitrogen cycle is driven by complex microbial transformations, including nitrogen fixation, assimilation, nitrification, anammox (anaerobic ammonium oxidation) and denitrification.

Abstract

STUDIES ON CRUSTACEANS SPECIES LIVING IN THE CORAL REEF AND THEIR ROLE IN ECOSYSTEM. Crustaceans are one of the most specis invertebrates in coral reefs, comprising approximately 20 % of all invertebrate species. This taxa often found clearly living in coral communities. The order Decapoda is the most common crustaceans observed the coral reefs due to their relatively large size and having bright colours. In addition, decapods contribute in the environmental balance and having important roles in coral reef ecosystem such as defending live coral from predators and helping growth of corals.
