Abstract

A knowledge of wave run-up behavior on a coastal structure is one of the most important factors affecting the design of coastal structures exposed to wave attack. Prediction of wave run-up on a coastal impermeable structure with slope face and various friction factors are discussed with simplifying assumptions. An analytical approach is given for predicting wave run-up based on data measurements as the parameters of  incident waves entering to coastal structure.  Statistical approach with Weibull distribution is given on prediction of wave run-up, and present the probability distribution of wave run-up height.

Abstract

This paper is to explain a case of evolution of property right regime of coral reef management: from an open access to state property and then to local governance, a case study of Gili Indah West Lombok, Indonesia. It demonstrates the reasons of change, the ineffectiveness of state property regime, and the emergence of local governance where conflicts are assumed as the triggering factors. The study found out that conflict of interest between two main stakeholders: tourism business operators (TBOs) and fishermen drove the change process. The conflicts initialLv emerged after Balai Konservasi Sumberdaya Alam (BKSDA) as the executor of the state property regimes was unable to protect the coral reef ecosystems from destructive fishing practice. It has also failed in halting Muroami application that has triggered lasting conflicts between TBOs and fishermen. The failure of the state property regime has led TBOs to take over the protection tasks through constructing local governance. So far, the local governance has been successful in protecting the coral reef resources and forced the users to use the coral reek in a sustainable manner. However, it still shows a number of weaknesses in dealing with new challenges such as the non-involvement of several stakeholders in making social agreements and the unequal distribution of authority and responsibility among the actors and stakeholders. Therefore, attempts to find an alternative regime that could address the new challenges ofthe reef management are still required

Abstract

The biology and population analysis of Australian pilchards (Sardinops eopilchardus) was reviewedand studied. The Australian pilchards stock was depleted in South Australia whereas in other statesare under-exploited. The population study was done using protein analysis. Six enzymes (PEPB,AH, PGM, EST, MPI and AAT), which showed polymorphism, were scored and used in thepopulation study. For future studies, frozen procedure techniques need to be improved and numberof samples collected need to be extended.

Abstract

Deep-sea environment characterized by its low temperature, high hydrostatic pressure, limited nutrient contents, and constant darkness has been a hostile environment for most marine microorganisms. Therefore it is a home for low temperature and high pressure-loving bacteria believed to functionally over shallow water intruders. Deep-sea has been regarded as rainforests in terms of their microbial diversity. Thus, the deep-sea should commend itself to microbiologists and biotechnologists alike as source of novel microorganisms and exploitable properties. Near Indonesia several deep-sea trenches exist with diverse environmental conditions. However, up to now there has been no effort to study the microbial communities of those deep-sea environments by Indonesian scientists. This is mainly because of the lack of knowledge in the field of deep-sea microbiology in Indonesia.

Abstract

Tradition of “sedekah laut” (sea thanksgiving) in the Pekalongan fishermen community is also “Nyadran” which is always celebrated every month of “Syuro”. This ceremony is the expression of gratitude to God having given safety and abundance of fortune in fish catching in the sea. In this tradition there are various manings, omens, symbols which can be used as philosophy of life for the fishermen. This tradition is unique and interesting; it is also the regional cultural wealth which should be preserved, especially for thourism interests.

Abstract

Zooxanthellae, Symbiodinium sp, are single cell dinoflagellate algae known to live in association with many marine invertebrates such as hermatypic corals, sea anemones, jellyfish and giant clams (family Tridacnidae). In giant clams, these photosynthetic algae are located in a tubular system (known as Z tube system) which occurs within the clams. Apart from filter feeding, the nutrition of the clams is provided by zooxanthellae. These algae are capable of translocating part of their photosynthetic products to the host. CZAR values are also discussed.

Abstract

Freshness of fish is crucial in determining the nutritional value and sale value of fishery products.Assessment of fish freshness can be done with various methods based on several principles of chemistry,physics, microbiology, and organoleptic. K value is one of freshness test based on ATP degradation.Analysis of K values can be done with Freshness Testing Paper (FTP III). This method is relativelypractical, easy, fast and the results can be accountable. The material that used in this study are fish milk fish(Chanos chanos Forsk) and short-bodied mackerel (Rastrelliger neglectus) with total 90 fish with anaverage weight of 99 grams / fish (milk fish) and 85 g / fish (short-bodied mackerel). The fish raw materialpurchased from Rejomulyo fish market (Semarang) and taken to the laboratory in a Styrofoam box that wasgiven ice on the inside. This research used an experimental method called descriptive exploration. Storageof samples was handled at different temperatures namely 30oC ± 2oC, 15oC ± 2oC and 1oC ± 0oC. Theobserved parameters include organoleptic test and analysis of K Value (FTP III). The results showed that Kvalues for all samples increased during storage at different temperatures. The highest K values of milk fishand short-bodied mackerel fish during storage at a temperature of 0°C was on 96-hours storage time. Thehighest K values of milk fish and short-bodied mackerel fish during storage at a temperature of 15 ° C wason 72-hours storage time. Whereas the highest K values in milk fish and short-bodied mackerel fish duringstorage at 30°C temperatures, was on the 24-hours storage time. The fastest increase in K value was observed at a temperature of 30°C compared to storage at a temperature of 15°C and 0°C for all the fish samples. This means that the deterioration quality of fish will be faster at high temperatures. K values of mackerel increased more rapidly than milk fish.

Abstract

Nutritional quality of lupin based shrimp (Penaeus monodon) aquaculture feeds was evaluated in terms of pellet water stability. Two series of water stability experiments were carried out to study the effects of lupin meal inclusions as an dietary protein alternative for fish meal (Experiment 1) and soybean meal (Experiment 2) on percentage dry matter and protein leachings of the compounded test diets.  Increasing the replacement levels of dietary fish meal with lupin meal resulted in significant decrease (P<0.05) of pellet water stability over the 480-minute immersion period. A significant improvement in water stability with the increase of the soybean meal replacement levels with lupin meal up to 50% was found, however, further increase above 50% substitution level resulted in reduced water stability of the diets. It is  concluded that lupin meal can not totally replace either fish meal or soybean meal in shrimp formulated diets and a 50% replacement level of dietary fish meal or dietary soybean meal with lupin gives a promising good result in terms of pellet water stability for P. monodon diets.

Abstract

In order to elucidate the role of hydrostatic pressure on the distribution of marine microorganisms, deep-sea water samples from north-western Pacific Ocean were collected and used as the source of barophilic bacteria. One isolate, JTW-863 was obtained from a depth of 6000 m, while two isolates, MTW-1 and MTW-13, were obtained from a depth of 10,500 m. Phylogenetic analysis based on PCR-amplified 16S rDNA revealed that JTW-863 belonged to Moritella, while MTW-1 was mostly related to Shewanella. On the other hand, MTW-13 was affiliated with the uncultured clone NB1-d from deep environment.

Abstract

A study to determine biodiversity related to ecological function of secondary mangrove forests at central Java had been carried out in three different locations viz. Rembang, Demak and Pemalang coasts.  Location of sampling was selected systematically in three levels of inundation within both lower and higher densities of mangrove. Sediment samples were collected randomly with four replications.  A lens tissue trapping method was applied to collect living benthic diatoms.  Primary productivity was measured in-situ in the locations as production of carbon per unit area per unit time. It was determined by dissolved oxygen content measured by the bell jar method.  Data were then analyzed using a biodiversity index (Shannon-Wiener index), ANOVA, regression and cluster multivariate analysis for b biodiversity. Totally, 86 benthic diatom species had been found and the benthic diatom community assemblage was dominated by Amphora coffeaeformis, Diploneis crabro, Diploneis smithi, Navicula elliptica, Pleurosigma sp., Stauropsis majuscula and Surirella gemma.  Benthic diatom abundance was 8.6750 x 104 to 18.9626 x 104 cell/m2, where the highest was found in Demak and the lowest was in Pemalang.  Abundance of the diatom does not always have significant relation (P > 0.05) to both inundation levels and mangrove density; however, this was more depended on location.  The assemblage of benthic diatom community was more similar in Rembang and Pemalang compared to that in Demak, however the a biodiversity index tended to be higher in the lower mangrove density.  The benthic micro-flora primary productivity was 120 to 342 mg C/m2/hour and had no significant relation (P > 0.05) to abundance of benthic diatom.  It was revealed that the optimum density of mangrove to have the highest benthic micro-flora primary productivity was between 8000 to 10000 trees/ha.
