Abstract

World crustacean aquaculture has developed considerably since the 1980’s and is now worth more than USD 10 billion per year. However, the economic growth of this industry has been severely affected by problems related to diseases and environmental degradation. Viral disease outbreaks are particularly concerning and have caused massive economic losses around the world. However, there is still no effective treatment for most viral diseases. Current research on crustacean diseases focuses on the role of innate immune system as the first defence mechanism against viral infections. Of the available antiviral immune responses, interferons (IFNs) are known to have ability interfering effect on viral replication, particularly in vertebrates. This paper reviews the function and molecules involved in the vertebrate interferon system and whether similar molecules and pathways may exist in crustacean immune systems. Therefore, IFN or IFN-like proteins in crustaceans may provide the key to managing viral diseases.

Abstract

Introduction : the problem faced in smoking fish is primarily related to deterioration of lipid caused by oxidation, that may cause of omega-3 fatty acid content in fish. This research was aimed at investigating the effect of different method of smoking fish to the organoleptic value, proximate composition and omega-3 fatty acid content. The experiment was carried out in The Laboratory of Coastal Zone Ecodevelopment, Diponegoro University, Jepara. Analysis of omega-3 fatty acid was conducted using Shimadzu Gas Chromathography in The Laboratory of Food Science and Technology, Tokyo University of Fisheries, Japan. Material and Method : a randomized design was used in this study; filleted skipjack tuna (Eutynnus affinis); approximately 125 gr in weight and about 25 cm in length was used in both coconut shell for the traditional method and liquid smoke from Giulini Chemii for modern method. The temperature of the smoking process was between 40 – 80 °C. Sensory test and proximate composition were determined in order to support an omega-3 fatty acid analysis. Result and Discussion : the average value of sensory test of traditional smoked tuna was between 3.00 – 8.33; liquid smoked tuna was between 6.67 – 9.00. the protein composition was 38.98% and lipid was 2.71% for the traditional product and 32.21% and 2.06% were obtained in liquid smoked tuna. Analysis of DHA resulted in 17.6% (traditional) and 20.9 (liquid). The results showed a significant difference between two products. The product of liquid smoked fish had better appearance, longer shelf life and higher omega-3 fatty acid content.

Abstract

Gonad maturation and sexuality in Central Java populations of A. granosa and A. antiquata were studied by means of macroscopic examination of the visceral mass, microscopic examination of smears of gonadal products and by histological technique. In this study, hermaphrodites occurred extremely rarely, i.e. less than 1.5% for A. granosa and less than 1% for A. antiquata, were observed with both male and female gametes present within the same individual follicles. Unbalanced sex ratios derived from size frequency distribution of the sample revealed that the increased percentage of females with increasing size suggest the occurrence of sequential protandric hermaphrodite with only a single sex change during their life history, i.e. from male to female. The preponderance of juvenile males within the Wedung population should be seen as the advantage of firstly being male, since some energy could be saved and redirected towards somatic growth because in Bivalvia there is a trade-off between growth and reproduction.

Abstract

Fecal coliform bacteria have been widely used as a biological indicator of sewage (domestic waste) pollution. However, as a biological indicator in urban coastal waters, it has disadvantage, in particular because of increased volume of industrial wastes that are toxic and heated, increase of salinity, and low dissolved oxygen. These conditions may affect the growth rate of most bacteria, including fecal coliform bacteria that becomes under representative in sewage pollution  in urban coastal waters. It is necessary to find alternative indicator that can be used to better understand the sewage pollution in urban coastal waters. Many researchers have proposed coprostanol as a chemical indicator of sewage pollution. To understand the existence of coprostanol and coliform bacteria, a preliminary study has been done on water and sediment samples from the river, river mouth, and seawater of Banjir Kanal Timur Semarang coastal waters. The results showed that coprostanol could be detected in sediment from all sites, on the other hand coliform bacteria decreased with the increase of salinity, and were not detected in the seawater.

Abstract

The increasing of energy demand for public transport and a rise of oil prices lead to intense of using green fuel for sustainable future. Red-seaweed polysaccharide consists of carrageenan can be used for production of bio-etahanol, as it supplies monosacharides. In this study, the possibility of bioethanol production using red-seaweed as raw material was examined. The purpose of this research was to determine the method of bioethanol production using red-seaweed. Two separate anaerobic fermentation following acid hydrolysis, each by different type of yeast, bread yeast (Saccharomyces cereviceae) and tapai yeast were conducted in this study. Acid hydrolysis for 2 h using H2SO4 of 5% at 100 oC of 100 g seaweed gel derived from 25 g of red-seaweed showed an optimal hydrolysis process yielded sugar content of 15.8 mg mL-1. Tapai yeast was not suitable for fermentation of red-seaweed hydrolysate, while Saccharomyces cereviceae gave an alcohol content of fermentate of 4.6% after 5-6 days of fermentation at room temperature.

Abstract

A CRS model has been applied to determine the ages and accumulation rates of sediment. This model assumes a constant flux of unsupported 210Pb to the sediment, allows the rate of sedimentation to vary over time. The applicable of CRS model was used to analysis of two bottom sediment cores (JB 17 and JB 11) from Jakarta Bay. The result show that sediment accumulation rates in JB 17 varied from 0.09 to 1.13 kg.m-2.y-1 and in JB 11 varied from 0.18 to 2.47 kg.m-2.y-1.

Abstract

Indonesia is a maritime country, composed about 17,500 islands. It has a great endeavor of open waterresources such as river, lake, dam, pond, swamp, etc. which are spread over the country. Multi-tribes and –races are attributed to its habits, tradition, and culture of the communities lived. Given such large territory,especially Indonesia is formed of thousands island, it will be costly to set a formal enforcement andsurveillance in securing the open-access resources (like fisheries, water, etc). Fortunately, each communityhas an indigenous or traditional system to manage the resources. For example: Ikan Larangan (in WestSumatra), sasi (in Maluku), Subak (in Bali), Sedekah Laut (in Java) and so on (Susilowati, 1996; 1999).Rather than waiting a complete formal resource management (and need to be set up by the government) anddo not know when will be effectively apply, thus it will be more reasonable and timely to revive thetraditional system of resource management belongs to the respective community. In short, communityinvolvement in resource management is urgently encouraged, particularly in developing country withlimited budget like Indonesia. This paper is attempt to compile an experienced of Co-management approachto manage the open water resource done by Susilowati (1999, 2002, 2004, 2006, 2007). An institutionalanalysis (Pomeroy and William, 1994) and Pinkerton (1989) with necessary modification were applied tothe respective studies. The results indicated that there is a fairly prospect to empower the competentstakeholders (community, government, private, independent parties) to be involved in managing the openaccessresources. However, all parties need to be encouraged for a high intention in participation,commitment and somehow to create their sense of belonging to advocate the resource management. It iseasy to say but hardly to be materialized all the things for Indonesian context, except the leaders (formal andinformal) in the respective region are really committed to conserve the resource.

Abstract

Conflict of  fisheries (capture fisheries cases  of purse seine) in the sea waters of Kotabaru South Kalimantan, require serious attention. The government has made ​​some efforts to overcome it but not yet effective. Therefore it is important to know more deeply whether conflict resolution is already addressing the root of the problem. The study was conducted with a qualitative approach. The primary data collected through in depth interviews with key informants, while the secondary data obtained from literature studies, relevant agencies and newspaper clippings. Based on the analysis results that: the root causes of conflict based on the source of relationship issues, structural problems and value differences and conflicts based on the typology of conflict of jurisdiction, internal allocation and management mechanism. The resolution of conflict using negotiation and facilitation techniques. Conflict resolution is done is still not addressing the root of the problem so that the escalation of conflicts of fishing last long. Conflict resolution needs to be done effectively by involving stakeholders and increasing their participation in creating the sustainability of capture fisheries.

Abstract

Marine biofouling has been recognized as a big problem faced by marine technology, and has caused huge economic losses to marine industries. Until recently, marine biofouling has been controlled by the use of metal-based coating which has become another problem because of their negative impacts on marine environments. Soft corals have been known to produce secondary metabolites, some of which may inhibit the fouling processes. The objective of this research was to examine the antimicrobial properties of soft coral Sinularia sp against marine biofilm-forming bacteria The results showed that the soft coral tissues of Sinularia sp. had the antibacterial potency. The crude extracts of Sinularia sp affected significantly on the growth of bacteria tested. The optimal concentration of crude extracts needed to inhibit the growth of bacteria was 150 µg/ml. There were no significantly different among bacteria isolated from fiber, wood and iron steel on diameter of inhibitory zone of the bacterial growth. It is concluded thet the search of bioactive substances produced by soft corals is great possibility to find alternatives for metal-based coatings. Yet, a series of researchs must be undertaken in order to find the secondary metabolites which may be used as antifoulant.

Abstract

Trace metal contamination of marine environments can be determined by measuring trace metalconcentration in sediments, water or biota. Biomonitor organisms have the advantages over othermeasurements that they concentrate the portion of metals that are in a biologically available form, and thisportion which is usually of interest when assessments is being made of trace metal contamination.Correspondingly, whole tissue trace metal concentrations of 4 metals in common Jakarta Bay benthic species(polychaetes, molluscs, crustaceans) from contaminated locations were measured. The mean concentrationfor Cu was 17.5 ± 21.8 μg g-1 dw in polychaetes, 11.9 ± 8.8 μg g-1 dw in molluscs, and 12.2 ± 5.5 μg g-1 dw incrustaceans. The mean concentration for Cr was 172.8 ± 262.5 μg g-1 dw in polychaetes, 31.8 ± 62.8 μg g-1dw in molluscs, and 28.5 ± 29.0 μg g-1 dw in crustaceans. The mean concentration for Zn was 152.4 ± 76.4μg g-1 dw in polychaetes, 132.0 ± 106.3 μg g-1 dw in molluscs, and 515.8 ± 503.5 μg g-1 dw in crustaceans.The mean concentration for Pb was 6.3 ± 13.6 μg g-1 dw in polychaetes and was 2.0 ± 4.5 μg g-1 dw inmolluscs. The study provides significant contribution to confirm the content of heavy metal in each commonbenthic species inhabits coastal Jakarta Bay.
