<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[Hypoxia is one of the aquatic phenomena caused by natural and/or anthropogenic factors. Eutrophication is the main trigger of hypoxia in coastal waters throughout the hemisphere. Hypoxia that occurs in aquatic ecosystems refers to the low concentration of dissolved oxygen in the water column to less than 2 mg/L. Hypoxia causes a double effect, low oxygen supply for biotic physiological process, and triggers ocean acidification. Prolonged hypoxic conditions will have a significant impact on the food webs in coastal waters and sea waters, further conditions will ultimately have an impact on capture-based fishing activities. The case of hypoxia in Indonesian coastal waters has not been widely revealed and has not been a concern to be understood or traced to its existence. Retrospective as well as actual traces of hypoxia were revealed, especially in the waters of Jakarta Bay. The retrospective study was carried out using proxies that have been used in various tropical and subtropical countries, the Ammonia-Elphidium (A-E) index (Foraminifera). The results show that several places in the coastal waters of Jakarta Bay and Semarang have experienced episodic hypoxic events for several centuries. A brief review of phenomenal hypoxic events in other parts of the world and preliminary information on recorded events in several Indonesian coastal waters are expected to open stakeholder awareness about further threats of hypoxia in Indonesian waters.]]>

<![CDATA[Persistent organic pollutants (POPs) have been identified as representing a serious threat to the marine environment and received formal attention by nations worldwide including Indonesia as one of the signatories and ratified countries for the Stockholm Convention. Due to their emerging issues, the study of POPs at all aspects is needed. Therefore, this paper attempts to review characteristics and toxicological properties of POPs, the current status of POPs National Implementation Plans (NIPs) in Indonesia, and propose future directions of POPs study in Indonesia from basic research such as monitoring of POPs distribution in Indonesian seas to applied research for example study of POPs alternative compounds.]]>

<![CDATA[Coral reef ecosystem is one of the coastal marine ecosystems in tropical waters. Coral reef ecosystems are vulnerable to damage mainly due to environmental factors. A fairly popular event of coral reef damage is coral bleaching. Mass coral bleaching is generally caused by changes in Sea Surface Temperature (SST). The condition of corals that have bleaching is different from the condition of corals that have died. The recovery process from coral bleaching phenomena can be effectively carried out if the surrounding environment is supportive and sea surface temperature return stable. The phenomenon of coral bleaching is a real indicator of the environmental stresses that occur on coral reefs. This paper will explain about coral bleaching, the factors that cause coral bleaching, and whether the bleaching coral reefs mean alive or dead.]]>

<![CDATA[In 2006, a tumult arose in the world of fisheries. A controversial paper titled “Impacts of biodiversity loss on ocean ecosystem services” by Worm et al. (2006) was published in Science. The paper was sensational since it alluded to a prediction that global populations of marine fish (finfish and invertebrates) will be 100% collapsed by 2048. The paper was written by a group of marine ecologists and economists in which Boris Worm from Dalhousie University Canada led the authorship. After the paper was published, the issue of fish disappearance in 2048 became hot topics in the world’s mass media. In fact, the Worm et al. paper triggered the debates among researchers. Over time the debates heated up. Surprisingly, a reconciliation took place in 2009, marked by a collaboration between Worm’s team and his critics, writing another paper in Science. The present essay reaffirms the invalidity of the global collapse prediction in 2048 as revealed by many researchers. It is also shown that the Worm et al. paper did not state that all fish will disappear and through the joint paper in 2009, Worm and colleagues have indirectly rectified the prediction already.]]>

<![CDATA[Consuming contaminated seafood can be potentially harmful for human health, especially for coastal communities. For this reason, a health risk assessment is very important to determine the safe limit for consuming seafood. Several stages in this assessment are; (i) direct comparison with the standard/maximum limit of heavy metal concentration determined by each country or international organization, (ii) determination of the maximum amount of seafood that can be consumed by adults per week, (iii) determination of the Estimated Daily Intake (EDI), and (iv) determination of the Target Hazard Quotient (THQ) of each metal and the Total Hazard Index (HI) for the combined metals.]]>
