Abstract

A marine bacterium associated with a soft coral Sinularia polydactyla collected from Bandengan water, Jepara, North Java Sea, Indonesia, was successfully screened for antibacterial activity against pathogenic bacterium Streptococcus equi subsp. zooepidemicus K6.72 isolated from infected monkey of the island of Bali and identified based on morphological, biochemical and molecular methods. Marine bacterium was identified as Pseudomonas sp. based on its 16S rDNA and was found to amplify gene fragments of Non-ribosomal peptide synthetase (NRPS). Cloning and subsequent sequencing, a 360 bp long DNA fragment was obtained and the deduced amino acid sequence showed conserved signature regions for peptide synthetases and revealed a high similarity of 61.1% to genes peptide synthetase of Bacillus subtilis.

Abstract

Dispersion modeling of natural radionuclides 238U, 232Th, 226Ra, 40K in Muria coastal waters has been carried out in sea water and sediment surounding Tanjungjati B coal-fire power plant and nuclear power plant site’s candidate by applying the hydrodynamics model of unsteady 2-dimensional flexible grid. Oceanography data collecting of bathimetry, current, wave, tide and wind had been carried out on May 28, 2006 until June 2006. Updating data was conducted on April 27 up to April 29, 2011 by using Acoustic Doppler Current Meter Profiler (ADCP) to measure the wave and subsurface current with duration of 2x24 hours. Sea water and sediment samples were collected on April 22, 2011 in six locations (surounding Tanjungjati CPP) and on April 23, 2011 in 10 locations (surounding NPP site’s candidate). Samples were analyzed at Research Center for Safety Technology and Radiation Metrology Laboratory, National Nuclear Energy Agency, Jakarta on May 2011 until September 2011 by using spectrometri-γ analysis. Result shows that it can be identified and measured the natural radionuclides of 238U, 232Th, 226Ra, 40K in sea water and sediment. The study can be justified that natural radionuclides of 238U, 232Th, 226Ra, 40K was leachated from fly ash and bottom ash of coal burned Tanjungjati CPP to sea water. The hiyrodynamics model of unsteady 2-dimensional fexible grid by using CD Oceanography software for current plotting, ArcView GIS 3.3 software for bathimetric contouring and SMS 8.1 software for modeling of natural radionuclides dispersion in coastal waters one can applied for radionuclides dispersion of 238U, 232Th, 226Ra, 40K in Muria coastal waters.

Abstract

The paper is based on the preparation by the author and two colleagues1 of a report on principles of sustainable development in Australia’s coastal zone, with a specific focus on the tourism industry. That report, prepared with funding under Australia’s Coastal Action Program, and following public comment and revision, has recently been published by the Australian Government under the title Coastal Tourism: A Manual for Sustainable Development (Commonwealth Coastal Action Program, 1997). The coast is an important part of the tourism industry’s attraction and resource base in Australia and many other countries. It is concluded that sustainable development and use of the coastal zone is crucial to the long-term profitability of the tourism industry and the quality of life of local citizens. The stage of the development process – from feasibility to operation and   management – are each considered of importance to sustainable tourism developments. A       number of guiding principles for such developments are spelled out in the paper, and issue such as self-regulation and the reasons that developers should consider sustainability in their activities are addressed. Additionally, reference is made to case-studies of sustainable tourism development that have occurred in Australia in recent years, and the lessons from those developments described. The key recommendation arising is that a valuable contribution to protecting coastal assets – assets upon which the tourism industry and the community depend – will arise from the formulation of environmental, social and economic criteria that developers can consider in planning, constructing and operating tourism ventures in the coastal zone.

Abstract

Jakarta Bay is located at the north coast of Jakarta bordered by 106 03'00'' Longitude and 6 10'30'' Latitude. Administratively bordered by Bekasi Regency on the east and Tangerang Regency on the west. There are  13 -19 rivers flow to the bay with 2050 industries  that produce hazardous waste, including heavy metals. Metal concentrations in surface sediments and their spatial distributions have increased, recently. Concentration of Pb during 10 years period increase from 23.3 mg kg-1 to 118.2 mg kg-1. The objectives of this study is to know the distribution of Chromium (Cr), Copper (Cu), Lead (Pb), and Zinc (Zn) of Jakarta Bay, Indonesia and their geochemical partition in marine sediments that are bound to “Exchangeable Fraction”, “Reducible Fraction”, “Fe-Mn Oxide Fraction”, “Oxidize able Fraction”, and “Residual Fraction”. The result showed that the concentration of heavy metals in the sediments in most locations were above the Canadian Standard for Contaminated sediments. Concentration of Cr ranged from 48.68—292.09 ppm, Cu ranged between 18.62—151.82 ppm, Pb ranged from 39.7—303.42 ppm, and Zn ranged between 165.83—487.69 ppm. Standard for Cr, Cu, Pb, and Zn are 22 ppm, 30 ppm, 25 ppm, and 60 ppm, respectively. Percent fraction of Cr in labile fraction (F1, F2, and F3) ranged from 30-60 %, while for Cu, its percent fraction mostly bound to lithogenic fraction as much as 38–78%.  Percent of labile fraction of Pb ranged from 22-54 %, while for Zn as much as 15-72%.  These meant that not only Cr but also Pb and Zn were possible to be easily released in the environment as bioavailable metals for biota, especially, benthic invertebrates.

Abstract

A short sediment core from the inner part of Jakarta Bay, Indonesia, was quantitatively analysed for ostracods (minute Crustacea), total organic carbon (TOC) and total nitrogen (TN) contents, and the vertical distributions were recorded. A total of 53 ostracod species were obtained from 80 continuous core samples. The dominant species were Keijella carriei and Loxoconcha wrighti, which are common in areas with high TOC and TN contents. Based on an analysis of ostracod assemblages and carbon/nitrogen ratio, the study site began to be influenced by organic contamination from around 1950. Although the population of Jakarta City has increased rapidly since then, TOC and TN contents which were low, have gradually increased (0.7%–0.9% and 0.10%–0.12%, respectively), probably due to addition of nutrients from river sedimentation. The increased sedimentation rate after 1950 resulted in an increasing TOC ratio. The observed correlation between TOC and dominant species shows that Phlyctenophora orientalis may be a good indicator for monitoring increases in the narrow TOC content range of 0.7%–1.1%.

Abstract

An open-system respirometer for measuring steady-state oxygen uptake rate of aquatic animals is described. The principle of the measurement was to calculate the difference between the oxygen concentrations of the water entering the respiratory chambers with that out from the respiratory chambers. This difference indicated the oxygen consumed by the animals for their respiration. The measuring system was tested to calculate the oxygen consumption related to dry body weight of scallop Pecten maximus L. collected from different populations. This correlation was  expressed by allometric equation as: Y = aXb. The equation was then discussed with the finding of several authors.

Abstract

Sea bass (Lates calcal&r Bloch), one of the economically important marine fish, is getting more important for marine-culture. This fish is categorized as a euryhaline species, i.e. with a wide salinity tolerance, range 32 — 35 ppt, and in the river, estuarine and mangrove areas with the salinity between 0 - 25 ppt. The adult of sea bass is spawn in marine waters while the larvae and juvenile are is spawn mostlv found in the estuarine. Estuarine water is known as a good nursery and feeding ground, however it is also knownias a pollutant trap. Therefore, the larvae of seabass and other euryhaline species are very susceptible to this condition.Suryizctant detergent Linear A lkyl—benzene SuU"onate (LAS} is a non—ionic so]? detergent, with a long straight carbon chain, has a powerful cleaning capability; it is toxic to aquatic organisms, and however it is biodegradable. Therefore, it is widelv used for cosmetic and household purposes. This research was done to find out the chronic effect (LCM-96 hours) and acute ejects of detergent LAS on the larvae of sea bass (Lates calcaliver Bloch}. A Bioassay method was applied to jind out the acute toxicity, and Probit Analyses is used to find out the LC 50-96 hours of detergent LAS on sea bass larvae. Randomized design was carried out to observe the chronic ejects on the growth and survival rate ofthe sea bass larvae. There were six treatments applied, i. e, : A (0% of LC ,,,-96 hours); B (5% of LCM-96 hours}; C (10% of LCM-96 hours); D (/5% of LC50-96 hours); E (20% of LCM-96 hours); F (25% ofLCm-96 hours).The results showed that the treatment of LCM-96 hours of detergent LAS on sea bass larvae, I. I8 mg/I, was considered as moderatelv high toxicity. The absolute biomass growth of sea bass larvae was not afected by sub·lethal concentrations of detergent ALS, however, chronic concentrations of detergent LAS tyfected the daily growth rate of sea bass larvae signyicantb¤ (o<0.0l). As a conclusion, the acute toxicity of LAS detergent on sea bass (Lates calcaliver Bloch} larvae was l. I 8 mg/l. The sub—lethal concentrations of detergent LAS on the sea bass larvae did not influence the biomass growth and survival rate but affected the daib¤ growth rate of sea bass larvae significantly. The sea bass larvae exposed to the sub lethal concentrations of LAS detergent hr 30 days resulted in the gill damage, i.e..· hypertrophy, hyperplasia, telengeastases and melanization of the gill. The congestion and vacuolar degeneration ofthe liver were also observed.

Abstract

Screening of extracellular chitosanase from bacterial isolates associated with marine sponges have been done. Out of 100 bacterial isolates, forty isolates were capable of forming clearing zones on the chitin media and one isolate, 34-b, produced the highest chitinolytic index. The enzymes was produced on chitin liquid medium at 37oC in a shaking waterbath for a five-day cultivation. Crude enzymes were prepared by cell-free supernatant (CFS) and concentrated through 70% (saturated) ammonium sulphate percipitation followed by dialysis. The enzymes worked best at pH and temperature of 6-7 and 60oC, respectively. The half-life (T1/2) for chitosanase activity was 500.2 min or 8.34 hours (at 37oC) and 55.12 min (at 50oC), indicating the enzyme are quite stable at that temperature. However, around 80% of the original activity was lost at 60oC after 15 min of incubation.

Abstract

Milkfish contains omega-3 fatty acids (DHA), which is very important to maintain the health of human being. The research is mainly aimed to evaluate the reduction of DHA composition during smoking process. Organoleptic value of the product i.e. : 8,1 for fresh fish; 8,59 for smoked fish A (3 hrs smoking duration) and 8,78 for smoked fish B (5 hrs smoking duration). The composition of fish changes normally  i.e. moisture content of 75,03% (fresh fish) decreases to 70,08% (A) and 68,11% (B). Protein composition increases from 20,30% (fresh fish) to 23,95% (A) and 27,50% (B). Lipid content increase from 0,61% (fresh fish) to 1,79% (A) and 3,53% (B). Ash content changes from 1,35% (fresh fish) to 2,03 (A) and 1,89% (B). SPSS analysis of DHA found of  p < 0,05 means that A and B were significantly different. DHA content was found drastically decrease from 121,19 mg/100g (A) to 16,4 mg/100g (B). ANOVA result proved that there is an interaction between smoking duration and the composition of DHA. Smoking duration is recommended no longer than 3 hrs in order to maintain its quality and minimizing the reduction of DHA. hange�� :>p� x� pan>

Abstract

The mangroves have adapted themselves best in the shallow sea coast, sheltered estuaries and deltaic:ones ofthe tropics and subtropics with characteristic environmental conditions vi:. temperature ranges between 200 C to 300 C, moderate to high monsoon precipitation i.e. [000 — 3000 mm/ annum, high humidity but with coastal aridity. On the sea-land intedace in global mangrove systems, there are gradual, slow or quickly changing ecological or geomorphological conditions to which mangroves have to adapt. The human thrust or pressure, other biotic factors and interactions also cause changes in mangrove ecosystems. Due to this the mangroves are now very dynamic but have become fragile through out the globe. Mangroves have various adaptations to cope with the stress to which they are subjected and jbr these adaptations they have to expend a lot of energy. Increased salinity has brought about floristic changes in the mangroves, particulariv in growth, form and structure of plant parts such as pneumatophores. thickening of leaves, salt extruding glands, viviparity stunted tree growth of some species and changes in plant communities. The mangrove forests stand as a barrier between the land and the sea and are jeeding and breeding grounds for dgferent fishery organisms. The mangroves if the world especiallv of the Indian continent are threatened and are on the verge of losing their identity. The study on the distribution of mangroves and the associate plants along Ulhas river estuary and the Thane creek during the period September 200] to August 2002 showed presence of 8 genera and I4 species ey' mangroves and I I genera and I2 species ry mangrove associates. The dominant mangrove type was Avicennia marina where as Acanthus ilicyblius was the mtyor associate type. When compared with the earlier data it was apparent that the mangrove cover was signtficantlv reduced The main threat to mangroves was due to anthropogenic activities, like cutting for jitel; reclamation for various purposes such as industry, agriculture, sand landing (reti-bunder), solid waste dumping, aquaculture ponds, construction of housing colonies, roads and bridges violating the CRZ regulation. There is an urgent need to conserve the mangroves of this region; which can be achieved through education, motivation of local people and strict supervision by administrative bodies and non-government organi:ations
