Abstract

The growth of giant gouramy in the pre-enlargement phase is very important, so the fish can grow and develop optimally until the enlargement phase. Water temperature is one of the many factors that directly affect the growth of fish. Water temperature significantly affects the rate of egg hatching of giant gouramy and the development of larval organs. The aim of this research is to determine optimum of water temperature on the growth of giant gourami fingerlings in pre-enlargement phase on controlled tanks. This research used a completely randomized design method with four treatments and two replications. The treatments in this study were: Control (maintenance without water heater); P1 (maintenance at 30 oC); P2 (at 32oC); and P3 (at 34oC). This research was conducted for 30 days by using giant gouramy fingerlings measuring 3,11± 0,14 cm with 50 ind/tank. The results showed that giant gouramy fingerlings was cultured at 32oC experience an absolute length growth of 5.29±0.21 cm, a daily growth rate of 3.32±0.07% and a survival rate of 94±2.82%. This indicates that the maintenance water temperature of 32oC is able to provide optimal growth for giant gouramy fingerlings in the pre-enlargement phase.

Abstract

The goal of this research was to find the optimal media for growing B. cereus bacteria with various carbon sources. This study used an experimental method with two Bacillus cereus bacterium isolates, namely B. cereus strain SN7 (isolate N) and a consortium of bacteria isolates (a combination of several B. cereus isolates with different strains). The two isolates were grown in sago liquid waste media, tofu liquid waste media, and molasses liquid waste media supplemented with a protein source, skim milk, with three replications in each treatment. Bacterial culture growth was measured every 6 hours for 24 hours using two methods: the TPC method and bacterial cell biomass measurement. According to the results of this study's measurements, molasses waste media was the best modified medium for B.cereus growth. The difference in growth between the B. cereus strain SN7 bacterial isolates and the consortium cultured on molasses media was not significant. The isolates with the largest number of cell growth were B. cereus consortium isolates, with 2,023 x108 CFU/mL in the TPC method and 1,011 g/mL in the biomass measurement method at 24 hours.

Abstract

Mangrove ecosystems are unique ecosystems found along the coast or river mouths that are still influenced by tides. Association is a process of interaction between organisms and their environment which is not simple but a complex process. One of the biota associated with mangroves is macrozoobenthos. This research was conducted in August 2021. The purpose of the study was to determine environmental conditions, mangrove species and density, macrozoobenthic species and density, and the relationship between macrozoobenthic density and mangrove forest density in Dumai waters. Based on the results of the study, the types of macrozoobenthos were found from the gastropod and bivalves classes. The type that is found in all stations is Nerita lineata. The highest density is at station III, which is 19.11 ind/m2. Mangroves in Dumai waters are classified as dense with the dominant species being Rhizophora apiculata and Xylocarpus granatum. The relationship between the density of macrozoobenthos and the density of mangroves belongs to the medium category.

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.

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.
