Abstract

The oceanographic research in Nangroe Aceh Darussalam waters post-tsunami was conducted on September 2006. Foraminifera which easily found as element of marine sediment was used as a tool to understand the trace effect of tsunami to marine sediment on the research area. Foraminifera is a single cell organism which has hard cover (test) as a primitive skeleton, that would remain in sediment for a long periods. Samples were carried out from west, north and east part of Nangroe Aceh Darussalam (NAD) Province waters using box-corer. The result showed there have been a mass of energy that force the sediment sliding and triggered the mixture of shallow and deep species of foraminifera in research area, particularly in western part of the waters.

Abstract

Lemuru Fish (Sardinella  longiceps) have high enough of protein contents (17,8-20%). However, lemuru fish also contains important fatty-acid, especially omega-3. Because of the contains of fatty acid was high (1-24%) and the texture is not compact, the fish become easily be broken and become spoiled. That was because of the activity of microbes or the autolysis on the post morterm. Because of that, the right and intensive handling is needed , it can be done with immediate process or with long-lasting storage. In this research, the pickling method that used was smoking with liquid smoke. The purpose of this research is to find the optimum operation condition for liquid smoke process of fish lemuru to produce lemuru fish that its fatty-acid Omega-3 did not decomposed and the fish has unique taste. The methods of this research was completely random design with concentration of liquid-smoke as the treatment and duration of liquid-smoke as the block. The fixed variables are the weight of fish, fish thickness, temperature, salt contained and duration of measurement. The non-fixed variable is concentration of smoked-liquid. At the condition where the concentration was 6% , 25 minutes of  the soaking time  gave the best optimal condition which the score shown was  EPA =  0.6066 g/100g ,DHA =  0.4033g/100g,  TBA = 0.86 mg/kg, TVB = 4.432 mg N/100g, TMA = 5.47% mgN and the total of microorganism is 3.62 x 106 CFU.

Abstract

In Sri Lanka many estuaries and lagoons are fringed with vastly diverse mangrove forests. The total mangrove cover is very small as 0.1 to 0.2 percent of the total land area. The distribution of fauna and flora varies along with wet and dry zone in the country. Around 25 species of flora are exclusive to mangroves and more than 25 species can be identified as associated mangroves. Variety of invertebrates and vertebrates are conspicuous in the mangrove forests, but only a few species are confined to the ecosystem. Heavy utilization and reforestation for shrimp farms and building construction work severely affect on this ecosystem. When compare to decline rate of mangrove forests in Sri Lanka, current implemented conservation measures are inadequate.

Abstract

Studies on distribution of organochlorine pesticides in water column and sediments from Banten Bay were conducted during transitional season on April and October, 2001. The objectives of the study were to determine the concentration and distribution of total organochlorine pesticides in water column and sediments in transitional seasons, and  to identify its sources. Our study showed the concentration of pesticides organochlorine in water column ranged between 0.366 and 4.391 ng/l  with an average of 1.952 ng/l  in April (location 1), and  0.357 and 2.998 ng/l  with an average of 1.203 ng/l in October (location 2). And then pesticide concentration in sediment were ranged between 0.263 and 2.090 µg/l dry weight (dw) with an average of 1.281 µg/l  in June (location 1), and 0.068 to 10.095 µg/l dw with an average of 1.775 µg/l in October (location 2). The result indicated different influence of the season on organochlorine pesticides concentration and there was fresh input of DDT in the study area.

Abstract

The determination of bivalvae demographic structure were conducted in Rembang Waters, central Java. The samples were collected and observed in situ, from February to May, 1996 and coverd 3 species, which are Mactra sp., Solen sp. and Pholas sp. The Von bertalanffy Growth Curve allows the determination of bivalvae population growth and their evolution. This is in regard to their presence according to sampling time and their abundances. The growth model was adjusted by several approaches, using the computer program, called DATAX . It was found that, the general pattern of bivalvae demographic structure was directly related to the ecological capacity and hydrodynamic factors of sampling area.

Abstract

Seagrasses have been known to produce secondary metabolites that have important ecological roles, including preventing from pathogen infections and fouling organisms. A research aimed at screening the potential of bacterial symbionts of seagrass Enhalus sp. was performed. Bacterial symbionts including endophytes and epiphytes were isolated from the seagrass, and marine biofilm-forming bacteria were isolated from the fiber and wooden panels from the surrounding colonies. A total of 17 epiphyte and 6 endophyte isolates were obtained, however more biological activity was found among endophytes (100%) compared to epiphytes (47%) against biofilm-forming bacteria. In addition, bacterial endophytes inhibited more biofilm-forming bacteria than epiphytes. Interestingly more isolates were obtained from rough surfaces both from fiber and wooden panels than smoothe surfaces. Bacterial symbionts of seagrass Enhalus sp., in particular its endophytes show potential source as  natural marine antifoulants.

Abstract

The study was conducted due to high incidence of non-compliance by fishers in Central Java fisheries. The overall objective of the study is to examine the compliance behavior of fishers in Pemalang Regency. Eighty-five (n=85) respondents have been selected from the study areas using multi-stages sampling method. Moreover, key-persons from Fisheries Office, Navy and head of fishers’ association have also been interviewed  to enrich the analysis of the study. Non-compliance behaviour of fishers in this study was viewed from violation of: restricted area (zoning), restricted gears and means (explosive and poison) and administration (such as permits). Model of non-compliance behavior as outlined by Kuperan (1993) and Susilowati (1998) has been applied to analyze the data in this study with necessary modification. Tobit model explained by Gujarati (2003) was employed as the estimation techniques. Most of independent variables such as demographical factors, fishing effort, deterrence indicators and legitimacy variables have expected signs although statistically are not always significant. In general, the model of non-compliance behaviour could portrait the phenomena of violation behaviour of fishers in the study area.  It is realized that  law enforcement in Indonesian fisheries is weak  for several reasons. Therefore, to improve the fishers’ compliance perhaps an alternative approach such as empowering the people and its stakeholders should be found.

Abstract

A mass-balance trophic flow model is constructed using a simple model termed ECOPATH. The model is applied to an ecosystem at Awur bay, Jepara in the northern central Java sea. The model constructed was built based on twelve components of the ecosystem, which were partitioned into groups of similar species and provide for these species groups, estimates of production biomass, diet and food consumption. Three tropic level of the components were clearly presented in the model. A number of the estimates mean biomass was 3922.054 gC.m-2.yr-1, while net primary production was 78439.48 gC.m-2.yr-1, over 115 ha area at Awur bay, northern coast of Central Java.
