Abstract

The Department of Maritime Affairs, Fisheries and Food (DKPP) of Nagan Raya Regency is a fully authorized body in managing all fisheries, marine and food activities in Nagan Raya Regency, Aceh Province. One important factor in supporting the productivity of capture fisheries is fuel oil (BBM) for small and medium fishermen. The fulfillment of fuel for fishermen is influenced by the length of stay at sea, the distance to the fishing ground, the size of the vessel, the type of equipment used, the vessel used and the fuel used. The fuel recommendation information system for fishermen is influential as the carrying capacity of information effectiveness between the service and fishermen. The information system itself is a group of elements that are interconnected or interact to form a single unit with an approach using quantitative methods and participatory observation. make a solution to the DKPP Nagan Raya as an effort to create a BBM Information System Application with the aim of facilitating an information system or fuel data collection, data collection of fishermen, and data collection of fishermen's catches. The BBM Information System application with a click using the fisherman's android will be greatly facilitated in the BBM recommendation process because it is in accordance with the quota received. In addition, this application method also makes it easier to monitor and report fuel distribution to fishermen, because everything can be integrated and can be monitored directly by the Marine Fisheries Service of Nagan Raya Regency.

Abstract

Hematological analysis of plasma proteins by testing for hemoglobin, erythrocytes, and leukocytes against ectoparasite infection in cages was carried out by taking samples of fish with consumption sizes of 15-20 cm. The aim of this study was to find out the amount of exposure to ectoparasites internally in the body of tilapia based on blood protein hematology test. Analysis of the data used is analysis of variance (ANOVA) with the aim of knowing the effect of sampling and the parameters tested. The results showed that the presence of infection identified normal hemoglobin levels of 7.438 g/dL, erythrocytes were quite low at 1.5605 x1012/L, this is the nutritional factor given to tilapia and leukocytes were still in normal condition, namely 61.985x109/L. The ectoparasites found were Streptococcus sp, Lernaea sp, Aeromonas sp, and Trichodina sp. The effect of the value of plasma protein content in blood for hemoglobin and leukocytes is still in normal condition, but erythrocytes are below the normal point so that from internal factors of tilapia disease, hematological blood plasma protein affects tilapia disease, especially on erythrocyte variables that affect fish anemia to mass death. This is in accordance with the situation in the field where tilapia in the KJA (Floating Net Cage) experienced sudden and mass death in a short period of time even though previously routine controls had been carried out by cage cultivators. When fish experience stress, fish blood glucose levels will increase while fish blood plasma total protein levels decrease.

Abstract

Nugget is one of the processed products from fish meat, whether fish is economically important or not. Nuggets are very popular with various circles of society because of their savory and delicious taste. Nuggets are made from fish meat and are believed to have a composition of nutritional value that is needed by the human body. This study aims to see the effect of adding egg whites to the organoleptic test of the nuggets produced and to see the level of preference of the panelists on the refined anchovy nuggets produced. The usefulness of this research is the diversification of processed fishery products that can be consumed by the community and has important economic value and it is hoped that the research results will be useful for the community about new sources of information regarding egg white substitution can produce anchovy nuggets (Stolephorus, sp) with good organoleptic tests. The method used is an experimental method. In this study, there were 2 treatments, namely there were two treatments A (egg white concentration) namely A1 = 50 g egg white, A2 = 100 g egg white A3 = 150 g egg white and treatment B ( heating temperature) namely B1 = 40 0C 15 minutes, B2 = 65 0C 20 minutes, B3 = 95 0C 30 minutes. In this study, subjective observations were made including color, texture, folding, and taste tests carried out by 15 panelists. The results showed that the administration of egg whites and heating at a temperature of 650C produced a good gel nugget color, due to a change in the color pigment. Egg whites can inhibit the softening of the gel because when heated, the value of the texture of the nugget becomes better. Meanwhile, the folding test value obtained was very high, namely 3.754, due to the fact that egg white inhibits serine proteinase so that the gelling strength increases
