Abstract

Abstract The increase in value-added of fishery products is one of which can be done by processing. In addition to maintaining the value of the protein in the fish raw material, it would be easier if the product is stored and increase the sale value of the fish itself. The ability to perform in the fish processing in Mandangin island is still very limited. Community service activities that have been carried out by a team of the Faculty of Fisheries and Marine Universitas Airlangga was introduce smoked fish product processing with liquid smoke,because this method easier and faster so that the products can be marketed. Liquid smoke was developed because the location is very minimal in the supply of raw materials such as firewood and coconut, so the use of liquid smoke is very appropriate. The resulting refined products are expected to be a source of protein Mandangin Island community itself and is able to become an alternative source of income for the community to increase the sale value of fishery products. Mentoring process being conducted by a team from the Faculty of Fisheries and Marine Universitas Airlangga so that the products can be marketed outside Mandangin Island or even to other areas in East Java.

Abstract

Abstract Needs of catfish seed always increase every years, especially for farming activities. Fulfillment demand of seed in large quntities and continuing are the main obstacle in the production process of catfish. This can be overcome by the process of cryopreservation. This process requires diluents and cryoprotectants to maintain the fertility of spermatozoa. Skim milk and egg yolks diluents has been used on fish because it was applied to carp and showing a good result of sperm motility and fertilization rate. Glycerol as cryoprotectant was reported effective to be used for European Catfish than the other kind cryoprotectant. This study aimed to determine the effect of different concentrations of glycerol in the diluent skim milk and egg yolk on the motility and viability of catfish (Pangasius pangasius) spermatozoa after freezing. This research method is the experiment with completely randomized design (CRD) as the experimental design. The treatment used is different glycerol concentrations, P1 (11%), P2 (13%), P3 (15%), and P4 (17%) and each of the treatment was repeated 5 times. The main parameters measured were motility (%) and viability (%) of spermatozoa. Supporting parameters include odor, color, pH, viscosity, sperm concentration and catfish (Pangasius pangasius). Analysis of the data using Analysis Of Variance (ANOVA) and to determine the best treatment performed Duncan's Multiple Range Test with 95% confidance interval. The results showed that the effect of the concentration of glycerol in the diluent skim milk and egg yolk was not significantly (P> 0.05) on the motility and viability of catfish (Pangasius pangasius) spermatozoa after freezing. Further testing needs to be done on the level of fertility of frozen sperm, as well as the growth rate of seeds produced from sperm frozen catfish (Pangasius pangasius) products

Abstract

Abstract Sea water is a component that interacts with the terrestrial environment, where the discharge of waste empties into the sea to the mainland. One of the most dangerous pollutants for human health is the heavy metal plumbum (Pb). Bioremediation offers a promising alternative method and the potential to reduce the concentration of heavy metals in water. Bioremediation is the application of biological processes to recover a contaminated place by using microorganisms. Biomass of algae Nannochloropsis sp. can be used as bioremediation of heavy metals because it has the ability adsorption caused the active cluster contained therein. In addition, Spirulina sp. thought to have the ability as an agent of bioremediation of heavy metal plumbum (Pb) because the proteins and polysaccharides are high. Information about uptake ability of heavy metal of plumbum (Pb) by Nannochloropsis sp. and Spirulina sp., in order to know how it compares to the ability of Nannochloropsis sp. and Spirulina sp. in absorbing the content of heavy metal plumbum (Pb). The method used in this study is the experimental method, the test T of SPSS analysis as the experimental design. Treatment given in the form of differences in the concentration of plumbum, which include, treatment A (Nannochloropsis sp. without the addition of plumbum), treatment B (Nannochloropsis sp. 0.9 ppm with plumbum concentrations), treatment C (Spirulina sp. without the addition of plumbum) and treatment D (Spirulina sp. with plumbum concentrations 0.9 ppm) of each treatment was repeated 5 times. The main parameters measured were real heavy metal plumbum (Pb) in water culture media Nannochloropsis sp. and Spirulinna sp. The results showed that Nannochloropsis sp. and Spirulina sp. able to absorb the heavy metals plumbum (Pb) so that it can be used as a bioremediation agent, where Spirulina sp. have higher ability in absorbing heavy metals plumbum (Pb) compared with Nannochloropsis sp

Abstract

Abstract Microalgae species Nannochloropsis sp. can used as heavy metal biosorben because of it's adsorption capability that caused by the active cluster which contained in that species (Sembiring et al., 2008). Chlorella sp. is one of phytoplankton species that has the bioaccumulation ability of heavy metals and easily cultivated (Arifin, 1997). Lead (Pb) is a mineral belonging to microelements, is a heavy metal and is a potentially toxic material. Water bodies that have been polluted by compounds or ions Pb because can lead to the death of aquatic biota, the number of Lead (Pb) present in water bodies exceeding the proper concentration (Palar, 2004). One way to anticipate the increasing heavy metal pollution in the water is to bioremediation. The research using experimentally, the research design used was completely randomized design (CRD) consisting of four treatments with five replications. The concentrations of heavy metals Plumbum (Pb) used is 0 ppm and 0.9 ppm. The main parameters in this study is the ability of bioremediation Plumbum (Pb) by Nannochloropsis sp. and Chlorella sp. SPSS analytics normality test results and test the ability of T 95% in Nannochloropsis sp. and Chlorella sp. in absorbing heavy metals Plumbum (Pb) concentrations of 0 ppm and 0.9 ppm indicate that the data is normal and the results obtained were significantly different / significant. While the analysis of SPSS test T on heavy metal absorption capability comparison Plumbum (Pb) concentration of 0 ppm and 0.9 ppm by Nannochloropsis sp. and Chlorella sp. showed that the results were not significantly different / non significant. On average results obtained, Nannochloropsis sp. have a higher capacity than Chlorella sp. in the bioremediation process of heavy metals Plumbum (Pb).

Abstract

Abstract Sea cucumber is a commodity fishery that is traded international. One of the sea cucumber that has economic value is the local sea cucumber (Phyllophorus sp.) believed that contain compounds can be immunomodulatory. Phyllophorus sp. is one of the three dominant species of sea cucumbers in abundance and distribution in the Surabaya East Coast (Winarni,dkk., 2010). Coastal environmental issues that deserve the attention is the problem of heavy metal pollution in coastal waters. The highest toxicity of heavy metals for aquatic animals and humans are mercury (Hg) (Widowati dkk, 2008). The purpose of this study was to determine levels of heavy metals bioaccumulation of mercury (Hg) in the local sea cucumber (Phyllophorus sp.) From the East Coast Surabaya and to determine the heavy metal content of mercury (Hg) in the local sea cucumber (Phyllophorus sp.) has exceeded the threshold or does not. The experiment was conducted on the East Coast Surabaya and analisys of heavy metal Mercury (Hg) in Balai Besar Laboratorium Kesehatan (BBLK) Surabaya. The method used is the method of field observation and analyzed descriptively. The results showed levels of mercury bioaccumulation of heavy metals (Hg) from BCFo-w value from 454.78– 802.05 and BCFo-s from 31,42 – 111,26. This shows Phyllophorus sp. have the ability to accumulate heavy metals with low until middle accumulation level category. Mercury content of the Phyllophorus sp. obtained range from 0.031 to 0.061 ppm, sea water ranged from 0.0015 to 0.0023 ppm and sediments ranged from 0.0417 to 0.112 ppm. Mercury levels in Phyllophorus sp. and sediment is below the NAB, but the sea water has exceeded from NAB. Water quality parameters are still in normal conditions in accordance with the quality standards KMLH (2004) that temperatures 26-28 º C, pH 7-8, salinity ranged from 28-29 "°, DO value range 4-5 mg / L and brightness between 2-3 m.
