Abstract

The 2D horizontal model has been simulated to investigate a sedimentation and erosion pattern in the basin of Pulau Baai port — Bengkulu Sumatera. The model was verified with observed data from the Indonesian Research Center for Marine Geology (Arifin et al., 2001). The simulation results of the hydrodynamic model shows a good agreement with the observed data. In -regard to the elevation of sea level, the difference between simulation and the observed data is about 4.6 cm, giving averaged error of about 2.93 %, and the difference in velocity is 6.8 cm/s or in the order of error of about 20.1 %. The results of the model on sediment transport qualitatively show comparable values to the observed ones, although in some parts of the area, the model is still to be adjusted. Simulation results show that the strong current occurs in the harbor channel during the time of spring flood tide with a speed of about 95.4 cm/s, while the ebb current is 54.1 cm/s. The results of the model on sediment transport show that the erosion area occurs in the northeastern part of the basin and sedimentation takes place in the southwestern to southeastern of the channel. The channel port is generally eroded, and sedimentation occurs in the mouth and the western part of offshoreward of the channel, and erosion is identified in the eastern part of the offshoreward of the channel.

Abstract

The stomatopod fauna of Seribu Islands, Jakarta Bay, and adjacent waters is still poorly known. This study reveals the existence of 30 species in this area. A new species belonging to Oratosquilla is described. Records of distribution for those species are based on the material collected from this  area only.

Abstract

Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) compound that is known to be reported toxic to marine flora and fauna. Remediation of this environmental pollutant using chemical and physical methods causes environmental issues. Bioremediation using marine has been applied to degrade such various PAH compounds. Screening of marine microorganism in degrading this recalcitrant is very importance for bioremediation application in Indonesian waters. The purpose of this study was to screen and isolate bacterial with potential application in biodegradation of phenanthrene and other harmful PAH in marine environments. Several potential bacteria strains were isolated from oil contaminated sea water in Cilacap area. Sequence analysis using 16S rRNA gene marine bacterium strain C.260 showed 96% sequence homology to sequence of Thalassospira sp. In biodegradation of phenanthrene, within 28 days experiments, this bacterium degraded 50% and 99.75% of phenanthrene in medium with and without enrichment with NPK fertilizer respectively. Using sublimation method, this bacterium also degradeds phenothiazine, fluoranthene, and dibenzothiophene.

Abstract

The estuaries at the northern coast of Jawa are good fishing grounds for the artisanal fishermen. They have been exploited heavily, and is becoming more so with the advance of technology in the form of motorized vessels. Does the exploitation provide a good livelihood to the fishermen? The outcome of the preliminary analysis of the fishing activities of artisanal fishermen in the Kendal area (Central Jawa) will be presented, the problems discussed.

Abstract

Research on transplantation of Acropora microphthalma was conducted at Barrang Lompo Island reef edge of South Sulawesi from September to December 2002. The aim of this research was to know the successful rate of several coral transplantation methods for rehabilitation of coral reefs, covering the survival and growth rates. The methods used were framework earthenware (FE), iron stake (IS), dead coral tying (DCT), where the mother colony (MC) was used as control. These transplantation techniques were applied at five meter depth in two stations, north and south sites of the island. The survival rate for each method FE, IS, DCT and MC at the northern station was 85.71; 42.86; 85.71; 57.14%, while for southern station was 85.71; 85.71; 71.43 and 85.71%, respectively. The growth rates observed for each method at the first station were 2.18; 2.02; 1.40; 1.05 cm, and for the second station were 2.56; 2.21; 1.61; 1.04 cm, respectively.

Abstract

The concentrations and the distribution of organotin (OT) compounds and booster biocides in sediment and biological samples from Indonesia, Malaysia, Thailand and Vietnam are reviewed. Basically, the concentrations of tributyltin (TBT) in these countries were within the levels that have been reported in developed countries. However, the concentrations of triphenyltin (TPT) and booster biocides were lower than the reported values. Concerning the spatial distribution of antifouling biocides, higher concentrations of OTs were detected in the industrial area and fishing ports. Among ASEAN countries, the highest concentrations of TBT and TPT were observed in Bitung, Indonesia, where many ships from Southeast Asia visit and is moored in the port. The ratio of detected alternative biocide differed from country to country. Especially, many booster biocides were detected and their concentrations were high in Vietnam.

Abstract

A number of 137,870 freshly hatched larvae of Portunus pelagicus (L) were reared in one thousand litre container. The combination of Brachionus plicatilis and newly hatched nauplii of Artemia salina were fed to the larvae. The number of megalopa obtained was only 277. Ecological factor such as temperature, salinity, pH and dissolved oxygen were recorded. The effect of different food sources of the previous authors are compared. The detail description of the four zoeal stages and one megalopal stage are made and figured with emphasis on the number and type of setae on each appendages. A pattern of zoeal chromatophores is also sketched and described.

Oxystomata constitutes the smallest number of species among the Brachyura collected during the BARUNA  EXPEDITION. Fourteen species, among which of two the idetification is doubtful, have been studied and included in this paper. Though only few species recorded, many of them are to be more closely studied to ascertain their true position In taxonomy.

Abstract

A positive Indian Ocean Dipole (IOD) took place in the tropical Indian Ocean during 2006. The evolution of this event started in July 2006 and intensified during August 2006. It was indicated by negative sea surface temperature anomalies, lower than normal sea level and supressed convection in the southeastern equatorial Indian Ocean in contrast to western counterpart. Peak negative SST anomalies exceeding 1°C were observed in the eastern basin during September-November coinciding with anomaous easterly winds along the equator and strong southeasterly winds along the coast of Sumatra and Java. The expression of this positive IOD was also seen in other physical variables: negative sea surface height anomalies about 30 cm and negative rainfall anomalies exceeding 8 mm/day were observed in the eastern basin. The events was terminated in December 2006 mainly due to warming of the eastern pole. The magnitude of this event determined by the east-west temperature gradient across the tropical Indian Ocean was the third largest in the last 30 years, after 1997 and 1994 events.
