Abstract

 The port was facility at the end of ocean, river, or lake for ship received and cargo moving as well as passanger to into it. The aimed of this study was knowing the extent to which the enviroment management Meulaboh city port assessed from ecological, economic, socio-cultural and institutional dimensions. The method in this study was conducted with descriptive. Value of IkB-LOLINGPEL was 20.5, while the value of the index dimensions ecological, economic, socio-cultural and institutional environment in the Meulaboh city port were 20.00, 76.00, 60.30 and 53.14 respectively. The results of statistical tests Rap-LOLINGPEL method was good enough to be used as a tool to evaluate the environmental management port in an area or region quickly (rapid apprissial).Keywords: IkB-LOLINGPEL, port, Rap-LOLINGPEL

Abstract

The shark has a yield  by-product from its  liver up to 20% of its body weight, 50% of the total fish oil found on the liver. The aimed of this study was to determine heavy metal content, fatty acid profilel, and parameter of oxidation after neutralization. The method of  heavy metal test for silky shark oil stated on the SNI and fatty acid analysis referred to AOAC. Neutralization used NaOH 18°Be temperature (40, 50, 60, 70, and 80°C). The result of oil neutralization with NaOH had heavy metal content meet to IFOS (0.1 ppm), fatty acid of SFA was 19.58% , MUFA was 19.26 %, and PUFA was 41.58 %. The oxidation result of silky shark liver oil neutralization indicated the best treatment at 50°C with peroxide value (PV), p-Anisidine value (p-AV), percentage of free fatty acid (% FFA), acid value (AV), and total oxidation (TOTOX) were 72,49±0,27 mEq/kg, 8,57±0,46 mEq/kg, 0,28±0,00%, 0,56±0,00 mg KOH/kg, 13,57±1,01 mEq/kg respectively.

Abstract

Cathepsin was proteolytic enzyme which is found animal tissues included fish. Cathepsin found in fish muscle tissue, cathepsin and other hydrolyzing enzymes were place in subcellular organelles and divided into two places,  that was in muscle fibers and extracellular matrix. The aimed of this study was to the characterization of cathepsin enzyme especially catfish. So that in enviromental condition that can increased the activity of cathepsin enzyme an approtiate handling process can be carried out. The method of analyze enzyme activity, while the measurement of protein concentration refered to Bradford (1976). The treatments in this study was determination temperature (30oC, 40oC, 50oC, dan 60oC) and substrate (1.5% 2%, 2.5%). The result showed of enzyme activity with detrmination temperature very influential and fluctuating, the optimum temperature was 30oC where the activity reaches 0.38 U/ml. The best activity treatment of substrate was 1.5% where the activity reaches 0.42 U/ml. BSA Standard curve with regression equation y = 0.95x + 0.109.Keywords: Cathepsin, enzyme, substrate, temperature

Abstract

Catfish (Clarias sp.) is one type of freshwater fish. Quality of deterioration of fish takes place in a very fast, so it takes the right treatment to inhibit decay processes that occur either chemically or enzymatically. The aimed of this studywas performed to determine the rate of quality deterioration of catfish phase pre rigor, rigor mortis, and post rigor during storage chilling temperature. The proximate value of catfish content for protein, moisture, ash,fat, and carbohydrate was 2.94%, 77.78%, 1.35%, 0.95%, 16.96% respectevely. Results of pH testedincrease from 6.61to be 6.81. TVB values of catfish had varies between from 14.18 to 739.2 mg N/100g, whereas TPC value from 0.95 x105to 55x105 colonies/g.Storage of catfish with chilling temperature was can inhibit quality of deterioration, becasuse  the lower remperature inhibit activities for microbiological, biochemical and enzymatic.

Abstract

Yellow fin tuna (Thunnus albacares) is one type of high economic value fish. The tuna fillet processing itself produces some byproducts including fish bones. The byproduct can be reused as a product and food material. This study aimed to know the chemical quality of the yellow fin tuna bone powder with different drying temperature. The method used were experimental with 3 treatments and descriptive analysis. The treatment of temperature drying (90oC, 105oC, and 120oC), and the method of proximate analyzed refers to SNI. The parameters observed were yield, moisture, ash, protein, fat and calcium content. The result showed that yellow fin tuna bone powder with different drying temperature was best at treatment with value moisture content of P1 = 10.99 %,  ash content of  P3 = 59.95 %, protein content of P1 = 15.84 %, fat content of  P3 = 7.05 %, calcium content of P3 = 20.75%  and yield of P1 = 22.92 %.
