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

MARINE SEDIMENT AS PROXY TO DETERMINE CLIMATE DYNAMICS IN THE PAST. Studying the dynamics of climate change in the past is important and necessary, because it can serve as a basis for understanding the modern climate and the causes of its variations and changes. Evidence of past climatic conditions is usually archived on traces in nature that provide a proxy of past climatic conditions that we can explore. One of the major sources of proxy data for paleoclimate reconstruction is marine sediment. Microfossils usually used for quantitative proxy is foraminifer, diatom, pollen and etc. For the purposes of paleoclimate, the most important material is foraminifera. The paleoclimate results from the remains of carbonate and silica organisms have been generated from four types of analyzes: (a) oxygen isotope composition, especially calcium carbonate in foraminifer test (b) quantitative interpretation of species and its spatial variation through (c) the ratio of Mg / Ca to the foram test, which is related to temperature, and (d) the morphological variation in certain species resulting from environmental factors.

Abstract

FUCOXANTHIN: A HIGH VALUE CAROTENOID FROM BROWN MACROALGAE. Fucoxanthin is carotenoid that can be found in marine brown seaweed (macroalgae) and diatoms (microalgae). Fucoxanthin has been isolated from brown macroalgae for its bioactivities study, including: Cystoceira barbata, Sargassum aquifolium, Sargassum filipendula, Sargassum ilicifolium, Sargassum wightii, Alaria crassifolia, Cladosiphon okamuranus, Cystoseira hakodatensis, Eisenia bicyclis, Fucus serratus, Fucus vesiculosus, Hijikia fusiformis, Ishige okamurae, Kjellmaniella crassifolia, Laminaria japonica, Laminaria ochotensis, Myagropsis myagroides, Padina tetrastromatica, Petalonia binghamiae, Sargassum fulvellum, Sargassum heterophyllum, Sargassum horneri, Sargassum siliquastrum, Undaria pinnatifida, Sargassum longifolium, Padina sp, Turbinaria sp, and Undaria pinnatifida. The amount of fucoxanthin depends on the species of algae. Fucoxanthin has been reported to have bioactivities, i.e. antioxidant, antiinflammatory, anticancer, antiobese, antidiabetic, antiangiogenic, and pigmentation inhibitory.

Abstract

NOTES ABOUT LUTJANUS, ONE OF MAIN COMMODITIES IN CAPTURE FISHERIES. The snapper, genus Lutjanus are commercially important fish species, distributed in tropical to temperate regions all over the world. This group is mostly reef associated marine fishes and several deep-water (>100 m) species. Genus Lutjanus contains the largest number of species, i.e. 72 species in the world and almost 33 species in Indonesian waters. The snappers are dioecious and gonochoristic organisms, this means that they have separate sexes and the sexual differentiation remains constant throughout their life span. They are carnivorous and the diet consist mainly of small fishes, crustaceans, mollucas, and pelagic urochordata.

Abstract

HEAVY METAL POLLUTANTS IN MANGROVE ECOSYSTEM. Mangrove is an unique tropical ecosystem with the marine, riverine, terrestrial and atmosphericcomponents influencing the occurrence, speciation, bioavailability and fate of trace chemicals. Mangrove ecosystem are one of the most threatened tropical environment due to habitat loss, aquaculture expansion, overharvesting and increase of pollution load. In this paper, the role of mangrove to act as a sink of pollutants, accumulation and biomagnifications of heavy metals is discussed.

Abstract

THE BENEFITS AND ROLE OF SQUID FOR HEALTH. Squids are rich in protein with a protein content 15-20%. Squids containing macro and micro minerals such as sodium, potassium, phosphorus, calcium, magnesium and selenium, besides that squid also comprise essential amino acids such as tryptophan, threonine, methionine, lysine, leucine, isoleucine, valine, phenylalanine, and non-essential amino acids such as glutamic acid, aspartic acid, tyrosine, cysteine, serine, proline, glycine, arginine and histidine. Squid ink contain alkaloids that potential as anti-inflammatory, antihypertensive, anti-diabetic, anti-microbial and anti-malaria agents. The benefit of Squids in the food industry are an enhancer of flavor and an artificial leather constituent in the biomedical field.

Abstract

POTENTIAL OF BIVALVE AS BIOINDICATOR OF METAL POLLUTION IN THE COASTAL AREA. Bioaccumulation database using various species of marine bivalves is useful to determine which species are suitable as bioindicators in pollution monitoring. In general, metal bioaccumulation in bivalve varies in every location and influenced by the biokinetics of each species depending on the environmental condition. Increasing accumulation of one metal will enhance the accumulation of other metal in bivalve tissue. This needs to be taken into account in interpreting metal concentrations in bivalve. Oysters and mussels have the potential as bio-indicators of metals, especially Cu and Zn, while scallops are more potential as bioindicators of Cd and Zn. Meanwhile, clams has the potential as a bioindicators of Zn. Change in shape (malformation) of bivalve shells due to heavy metal accumulation also observed. The rough structure, attachment of minerals to the shell, and thickening of the shell layer are some forms of changes in bivalve shell morphology.
