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

SOUTH JAVA CURRENT. Indian Ocean is influenced by the monsoon cycle. Monsoon cycle that occurs in the Indian Ocean influences the current patterns. Since a very strong westerlies occurs in The Tropical Convergence Zone (TCZ) at the equator, wyrtki jet is formed in the 40° - 80° W Indian Ocean on a transitional season. Its branchs are possibly formed when the wyrtki jet is in the equatorial west coast of Sumatra to the north and south along the western coast of Sumatra which eventually creates South Java Current (SJC). SJC flows southeastward during December–April and northwestward during June–October, when it is associated with coastal upwelling. SJC develop upwelling on a seasonal basis.

Abstract

GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROPHOTOMETRY AS A METHOD FOR ANALYZING HEAVY METAL. Heavy metal, mostly present in a (ultra) trace-level, becomes one of the hazardous pollutants due to its toxicity, bioaccumulative, biomagnification characters. Conducting a micro analysis of these trace-level pollutants, a sensitive instrument and method are strongly recommended. Graphite Furnace Atomic Absorption Spectrophotometer (GFAAS) offers a solution for the challenge. It uses the principle of light emission absorption by nascent atom cloud from the metals. The analysis has been developed in three stages of the tube heating programs, i.e. drying, ashing and then atomizing element at 3000° C. Since the injected sample is almost completely atomized, the sensitivity of GFAAS is extremely high and this value is covering up the disadvantages of the other analyses. Therefore, the GFAAS analysis is suitable fo ultra-trace analysis of ultra-trace pollutants like heavy metals in environment.

Abstract

PLASTICS POLLUTION IN THE SEA. Indonesia is considered as the second biggest plastic waste producer in the sea. Information on waste pollution and its impact on marine organisms in Indonesia is still limited. Waste disposal and solid waste (plastics) into the sea are continuously occuring; elevating the thoughts of global impact of plastic waste contamination. Increased use of plastic is a consequence of the development of technologies, industries and also the population. This paper is expected to provide knowledge and information of plastics that exist in the sea, especially Indonesian Sea.

Abstract

MICROBE CONTAMINANT IN JAKARTA BAY WATERS. High anthropogenic activity in Jakarta Bay is believed to contribute a fairly high contamination as evidenced by microbial contaminants such as Coliform and Escherichia coli. The high density of Coliform and E. coli as indicators of domestic contamination in Jakarta Bay as a result of an increase in the resident numbers who bring the flow of water to the springhead of the Jakarta Bay. It can be said that the polluted waters of Jakarta Bay and marine biota should be cultivated in this area as green shell should not consumed, because it can infect and cause gastrointestinal diseases. For that purpose, a research of microbial pollutants was conducted in Jakarta Bay in July 2015, and the results showed a very high density, especially in the West.

Abstract

RECOGNITION AND UTILIZATION OF SATELLITE IMAGE SENTINEL-2 FOR MARINE MAPPING. Sentinel-2 is a satellite launched by a collaboration between The European Commission and the European Space Agency in the Global Monitoring for Environment and Security (GMES) program. The satellite has a mission to scan the Earth’s surface simultaneously at an angle of 180 each satellite with a 5-day temporal resolution with the same appearance on the equator and has a spatial resolution of 10 m, 20 m, and 60 m. There are 13 multispectral channels including VNIR and SWIR. Four channels with 10 m spatial resolution adapt with SPOT 4/5 and user’s comply requirements for land cover classification. Six channels with 20 m spatial resolution becomes a requirement for other Level 2 processing parameters. Channels with 60 m spatial resolution are specified for atmospheric correction and cloud filtering (443 nm for aerosols, 940 nm for moisture, and 1375 for thin cloud detection). Based on these specifications, Sentinel-2 can be an alternative for users to obtain image data with spatial, temporal, radiometric, and spectral resolution is better than SPOT and Landsat. Sentinel-2 can be downloaded for free and easy by the general public. The existence of image by Sentinel-2 is expected to be used optimally, especially for remote sensing analysis in marine field.

Abstract

APPLICATIONS OF REMOTE SENSING TECHNOLOGY IN COASTAL AND OCEAN Many remote sensing applications are devoted to the coastal and ocean sector. Representative case studies are presented in the special issue “Advances in Remote Sensing of coastal and ocean”. Remote sensing techniques represent a powerful tool for landslide investigation: applications are traditionally sea surface temperature, marine habitat into three main classes, although this subdivision has some limitations and borders are sometimes fuzzy in coastal and ocean. Remote sensing combined with geographic information system (GIS) can be used as a technology tool to obtain information about the object quickly and accurately, including objects in coastal and ocean areas. Remote sensing data on coastal and marine areas specifically for the region in Indonesia have been widely practiced. The use of remote sensing data and GIS in coastal and marine areas can be used to determine sea surface temperature, determination of fish catchment area, and coastline morphological changes by adding other influential parameters. It can also be used to monitor a regional change by using multi-temporal recording data such as disaster monitoring, monitoring of land cover changes in coastal areas etc. Remote sensing data essentially can be used as an alternative technology in obtaining information at a cheaper cost when compared with the conventional way.
