Abstract

Coastal water is vulnerable to anthropogenic substances such as human activities by product in coastal land and  upper land area. Semarang coastal area is one of areas which has progressive development in northern coastal of Java Island.  The aim of this study was to evaluate ocean health status based on heavy metal contain and benthic foraminiferal characteristics as the bioindicator.  Sampling and laboratory activities were carried out in August 2010. Sampling stations were located on the estuaries of Western Canal Flood, Tanjung Mas Port and  Eastern Canal Flood.  The result showed that Tanjung Mas pool port had the highest Pb, Zn,and Total Organic Compounds (TOC) concentrations. The average of abnormal test of benthic foraminiferal (Ammonia beccarii) were also higher in Tanjung Mas port than in eastern and western canal flood. Keywords: assessment, coastal water, Semarang.

Abstract

Jakarta bay is a unique water since there are hydrological and ecological complexity. In general, the feature of these water consist of three ecological elements that are estuaries, coral reefs and open sea. Each of these ecological element has different hydrology, ecology as well as biological characteristics. As a form of meiobenthic community, foraminifera has adaptive behavior to each of ecological element of the waters. The observation on foraminiferal adaptive behavior due to the hydrological condition of Jakarta Bay was conducted from 2003 to 2009. The result showed that foraminiferal distribution was tend to pursue to the degradation water conditions and constructed a specific pattern. Coastal water and estuary were found dominated by Ammonia beccarii, Calcarine and other larger benthic foraminifera were common in coral reef area, Elphidium and Nonion depressulum were common in open waters area. Based on the diversity indices, the foraminifera in Jakarta Bay has a higher diversity compared to foraminifera in the coastal water of Semarang and Cirebon and among the ecological element of Jakarta Bay, reef area has the highest diversity index than coastal nor open sea area.Keywords: Foraminifera, Calcarine, Jakarta Bay

Abstract

Coastal area is the most vulnerable area to climate change. Cirebon coastal land in Western Java, Indonesia is low-lying coastal area which is one of the potential areal for fish culture and farming. There are also major transportation facilities for western Java province to the whole area in the island (Java) through this area. As low-lying landscape, populated and developing city, Cirebon should be considered vulnerable to future sea level rise. Geomorphology, geo-electric and remote sensing study were conducted during 2008 and 2009 in coastal land of Cirebon. The result showed that most part of coastal area in Cirebon was eroded in various scales which vulnerable turn to worst. Sea water was penetrating throughout several kilometres inland. Valuation on various land-uses would project 1,295,071,755,150 rupiah/ha/year of loss while sea level were rose 0.8 meters that would inundate various land-uses i.e., Shrimp, fish and salt ponds, rice fields and settlement in the area.Keywords: vulnerability, coastal, climate change, sea level rise

Abstract

Makassar strait is the very unique waters, the bottom topography was steep and complex, the waters masswas also exceptional since Indonesian through flow carried flavor water from Pacific warm pool to the area.To describe the exceptional of Makassar Strait hydrological characteristics through recent foraminiferalcommunity structure as a proxy, Oceanographical Expedition in Makassar Strait was conducted in October2004. Research Vessel of Baruna Jaya VII was used to carry out the research activities. Sediment layers arean essential tool on recording hydrological information in such period of time, and each certain layerpreserved certain information as a bench mark data at a time period. The result shows that there are 5genera of planktonic foraminifera which generated a bulk in sediment surface. Deep chlorophyll maximum inoceanic region of Makassar Strait was prominent factor generated living planktonic foraminifera in researchlocation. Benthic community was formed by 164 species from 78 genera. Water depth was affected to benthicforaminiferal diversity, distribution and species diversity, which reveal that water depth was limiting factorto benthic foraminiferal assemblage. Uvigerinid was the important taxa which make up 46 to 57 % of thebenthic specimen, particularly in river input yield adjacent area. Uvigerina asperula may considered as anindicator of OMZ (Oxygen minimum zone) in Makassar Strait.

Abstract

The oceanographic research in Nangroe Aceh Darussalam waters post-tsunami was conducted on September 2006. Foraminifera which easily found as element of marine sediment was used as a tool to understand the trace effect of tsunami to marine sediment on the research area. Foraminifera is a single cell organism which has hard cover (test) as a primitive skeleton, that would remain in sediment for a long periods. Samples were carried out from west, north and east part of Nangroe Aceh Darussalam (NAD) Province waters using box-corer. The result showed there have been a mass of energy that force the sediment sliding and triggered the mixture of shallow and deep species of foraminifera in research area, particularly in western part of the waters.
