Abstract

Coral reefs, mangroves and birds are becoming the major attraction of tourism in three islands - Gili Meno, Gili Air and Gili Trawangan (Gili Matra) - Lombok, Indonesia. Since the launching as a conservation area in 1993, tourism in Gili Matra has grown rapidly. On the other hand, the ecosystem continues to be degraded. Sooner or later, the ecosystem degradation will affect tourism and economic sustainability of the community in Gili Matra. The purposes of this study were to identify the stakeholders, and to map the ecosystem management problems in Gili Matra, to provide the basis for policy making in the future. The research method was depth interviews and focus group discussion (FGD). Identification of stakeholders was conducted using stakeholder analysis, while mapping of ecosystem management problems was carried out by participatory mapping. The stakeholders, who manage the ecosystem as tourism assets in Gili Matra, are: government, community and businessmen. The fishermen, tourists and businessmen are the primary stakeholders, meaning they have a high interest and the greatest influence on ecosystem management. Destructive behavior of stakeholders, especially the main stakeholders has led to the degradation of the ecosystem in Gili Matra, so it is important to nurture these stakeholders, to sustain tourism and economic viability of the community in Gili Matra.

Abstract

Cyanobacteria, in particular those found living in the ocean, are emerging as an importantsource of unique bioactive secondary metabolites. A plethora of natural products, mostly nitrogencontainingmolecules, have been reported with majority belonging to the polyketide synthase (PKS)and/or non-ribosomal polypeptide synthetase (NRPS) structural class. Curacin A and the dolastatinsare examples of important marine cyanobacterial metabolites possessing exquisite anticancerproperties. Genetic studies on the biosynthetic capacity of these marine microalgae revealed manynovel biochemical features pertaining to the enzymology of secondary metabolism. Biodiscovery ofmarine cyanobacteria for new therapeutic agents as well as harnessing its biosynthetic gene clustersrepresent an exciting and fruitful area of research in marine biotechnology.

Abstract

Coral reef is the most productive marine ecosystem in coastal waters. Unfortunately, this ecosystem has already suffered from non-sustainable human use including destructive fishing practices (bombing and cyanide), coral mining, over fishing, settlement pollution and uncontrolled tourism development. These affected the production of those fisheries resources in coral reefs. In order to manage those resources, such alternative to destructive use need to be studied. This paper reports alternative solution to destructive fishing practices  on coral reefs. The study has been carried out at Padaido Marine Tourism Park, the District of Biak Numfor, West Papua province, for about 2 weeks, 9-18 June 2001.  Survey method was used during the study.  The data were collected using Participatory Rapid Appraisal (PRA)’s method, with members of fisher group as the participants. Three kinds of reef fish groups are identified at the Padaido Islands waters, i.e. major group, target group, and indicator group. These include ornamental and consumption fishes.  Fish were caught with several fishing gears; while some of them are identified as destructive fishing practices, e.g. bomb, cyanide fishing. However, some of them can be recommended as sustainable fishing technologies, i.e. (1) squid jig, (2) troll line, and (3) hand line.

Abstract

Law 27/2007 is the very basic rules for making the composition as well as planning and management tool on the ocean / beach / small islands. Law 27/2007 assumed less informed and not recognized by the staff of the government or society in general. This paper aims to identify the extent of socialization of Law 27/2007 by the relevant stakeholders, identify what factors or variables that have been well received and well prepared to implement Law 27/2007. Coastal and marine areas are relatively large with a variety of problems into consideration in determining Sidoarjo regency as a research location. There are two factors that were assessed, namely the level of knowledge of the material or content of the Law 27/2007 and the level of readiness for the implementation of Law 27/2007. Factor is defined by a number of variables and indicators. Methods of analysis using the Multi Dimensional Scaling with ALSCAL procedure to map a number of indicators. Identify the level of knowledge and level of readiness for the implementation of Law 27/2007 on the respondents showed very weak. There are varying levels of knowledge, although the general information about the Act is informed by good, but the policies, programs and tools to implement the government or community level have not adequate yet.

Abstract

Marine bacteria associated with soft coral Sarcophyton sp collected from vicinity of Peucang island, Ujung Kulon, West Java, were successfully screened for antifouling activity against marine biofilm-forming bacteria isolated from the surrounding colonies of Sarcophyton sp. Six bacterial isolates were found to inhibit the growth of at least one of 7 biofilm-forming isolates.  The most active strain USP3.37 was identified as Pelagiobacter variabilis by using 16S rDNA gene sequence analysis. Similarly, the active strains USP3.3, USP8.43, USP3.12, USP3.16 and USP8.6 were identified as Arthrobacter nicotianae,  Shewanella alga, Pseudomonas synxantha, Pseudomonas falgida, Pseudovibrio denitrificans and Bacillus aquamaris, respectively. USP3.37 strain was found to amplify gene fragments of non-ribosomal peptide synthetase (NRPS).  This raises the possibility the use of softcoral bacteria as the source of antibacterial compounds for controlling the antifouling in the sea. Therefore,  this bacterium would be better to select eco-friendly antifouling compounds than the other antibacterial activities.

Abstract

The improper and uncontrolled uses of antibiotics against pathogenic bacteria have resulted inthe occurrence of Multi Drugs Resistant (MDR) strains. There is now an urgency to find alternativeantibiotics to combat the MDR strains. Sponge associated microorganisms are among of the mostinteresting and promising marine natural product sources, which produce polyketide and nonribosomal peptide products with various biological activities. In this study, marine bacteria wereisolated from sponge Aaptos sp. collected from North Java Sea, and were screened for antibacterialactivity against MDR strains. Three out of 64 bacterial isolates were successfully screened and werefound to be active against MDR strains, in which 2 isolates (SPA1 and SPA5) were active againstresistant strain Escherichia coli and 1 isolate (SPA21) against resistant strain Proteus sp., respectively.These active isolates were also capable of amplifying NRPS gene fragments necessary for thebiosynthesis of non ribosomal peptides. The identification results revealed that the active isolates areHalomonas aquamarina, Alpha proteobacterium, and Pseudoalteromonas luteviolacea

Abstract

Phase I study (1996/1997) indicated that the local protein materials at relatively low cost were found abundance in Central Java throught the year. Their nutritional levels i.e. protein content, amino acids profile and availability are suitable to be used for mud-crab feed development. It is therefore the selected protein materials such as : soybean, mysidaceae, trash fish and saga, are then subjected to the formulation of experimental diet for mud crab on-growing culture (Phase II study 1997/1998) The aims of study are to determine the nutritional performance of experimental diets (novel diets) for mud-crab scylla growth, food utilization and protein efficiency during the feeding trial. The study has been conducted in a 12 bamboo-cages of 1.0 x 0.5 x 0.70 m immersed in BW ponds at CZEL “Prof. Gatot Rahardjo J.S – UNDIP”, Jepara and the stocking density of wild mud-crab (50-60 gram) was 1 pieces /box (0.2 x 0.2 m). Experimental diet (pellet formed) consists of four treatments i.e. diet A (25% dietary protein level), diet B (30%),          diet C (35%) and diet D (40%). The growth and nutritional parameters observed as response to the experimental diets tested are : Individual growth and growth increment, Specific Growth Rate (SGR), FCR, NOU amd PER. The completely Randomize Design was adopted in this study and then followed by Duncans’s New Multiple Range Test in order to determine the difference among the treatments. The results derived from this study indicated that diet C (dietary protein level of 30%) appeared to be the best diet wheather for the growth (W and SGR0 or nutritional performance (FCR, PER, and NPU) and followed by diet B, D and A. Meanwhile, during the course of feeding trial water quality of experimental media remain in good condition to support ud-crab growth.

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.
