Abstract

Acauses of the decrease in vaname shrimp production was vibriosis. Vibriosis is caused by vibrio bacteria. A vibrio bacteria that plays a role in vibriosis is vibrio harveyi. Managing of diseases caused by vibrio harveyi is one of the best that provides immunostimulant assistance from natural ingredients derived from seaweed. Ulva lactuta is a green seaweed that has different substances that contain immune. Some of the compositions contained in Ulva Lactutawere Flavonoid Compositions, and the Composition of Polysaccharides that are Combined with Immunimulants The purpose of this study was to determine the effect and dosage used to improve the immune system in vaname shrimp. Combined with THC and Fagocytosis in the hemolim on vaname shrimp before infection and after infection with Vibrio harveyi bacteria.A dose of 2 ppm showed a significant difference (p <0.05) for all treatments.

Abstract

The Kutaraja Ocean Fisheries Port (PPS) located in Banda Aceh City is central to the fisheries sector in Aceh Province. Various types of fish have been landed at Kutaraja PPS, one of which is tuna/madidihang (yellowfin tuna). Tuna is not only in demand by the local market, but also international markets, especially Japan and America. This study aims to estimate the amount of tuna/madidihang (yellowfin tuna) production landed at Kutaraja PPS in 2018 and 2019. These estimates can help the Aceh Government in controlling the ordering of tuna/madidihang (yellowfin tuna) from within and outside the country, so that the number of tuna/madidihang (yellowfin tuna) caught and ordered can be balanced so that stock control can run well. The forecasting method used in this study is the Triple Exponential Smoothing method by using monthly data on the amount of tuna/madidihang (yellowfin tuna) production landed at Kutaraja PPS from January 2010 to December 2017. Based on the results of forecasting with the best models, the amount of tuna/madidihang (yellowfin tuna) production will landed in the Kutaraja PPS in 2018 and 2019 are predicted to be 2,395,615.8 Kg and 2,451,207.5 Kg respectively.

Abstract

Gill nets is the most dominant fishing gear used by fishermen in Kampung Nelayan Village. Gill nets 2 and 3 inches are widely used by traditional fishermen and modern fishermen because this tool is very practical to catch fish also friendly to the environment. This study aims to determine the construction and friendliness of fishing gear gill nets 2 and 3 inches which include the length of the net, the width of the net, shortening, buoyancy and sinking power. This research was carried out in the Village of Kampung Nelayan, Tungkal Ilir Subdistrict, Tanjung Jabung Barat District in February 2018. The method used in this research was survey method. The data obtained were analyzed using net dimension analysis and descriptive statistical analysis. Based on the results of research on the construction of 2 and 3 inches gill nets consisting of nylon monofilament made from transparent colors. The knot used by the English knot. Top rope, float, and float buoy made from polyethylene (PE) rope and ballast rope made from polypropylene (PP). The sinker made from tin and gill net 3 inch weight based on bracelet-shaped wire.Net shortening value of 2 inch is 51.75% and has a buoyancy of 3.05 kgf and a sinking power of 9.97 kgf. As well as the value of gill shortening 3 inch 50.62% and the buoyancy generated 6.22 kgf and the sinking power of 365.4 kgf. The value of environmental friendliness of 2 and 3 inch nets has a value of 31.25 and 30.75 and is classified as environmentally friendly fishing gear.

Abstract

Diseases is a problem in aquaculture, one of which is the diseases caused by the bacteriumP.fluorescens. Antibiotics and chemicals materials themselves can give the bacterium resistance and cause harm for the environment. One alternative that can be done is using a natural material, namely the rod of ciplukan (p. angulata). The purpose of this research was to explain the effect of P. angulata on the growth of p. fluorescens. The method which can be use is experimental method by using the research design of completely randomized design (ral) with 5 treatment and 2 control with 3 repetitions. The results showed that extract of P. angulata at various dose (6,67 ppt, 13,33 ppt, 19,99 ppt, 26,66 ppt and 33,33 ppt) exhibited anti-P. fluorescens activity with inhibition zone diameters in the range of (4,06±0,07 mm - 9,63±1,61 mm). Increashing extract dose lead to increased the inhibition zone. The extract dose of 33,33 ppt exhibited best anti-P. fluorescens activity in this research. The research results show that P. angulata is proven to be able to inhibit the P. fluorescens, but to prove the effectiveness of this material, an in vivo is required.

Abstract

Fiddler crab (Uca sp.)one of the crabs that inhabit the intertidal area, especially around the mangrove forest research was conducted in the mangrove areas Curahsawo, district of Gending, Probolinggo, East Java in April 2017. The aim of this study is to determine the structure community violin crabs in the mangrove areas Curahsawo Probolinggo. The measured parameters namely pH, soil organic matter and soil texture. Sampling point there are three stations, namely station 1 is mangrove area, station 2 is in the pond area, the station 3 is the estuary area. Results of measurement of environmental quality at the location of research is soil pH among 7.09 to 8.03, soil organic matter among 1.027% to 3.106%, and the type of soil is sandy clay and dusty clay. fiddler crabs are found in mangrove ecosystem Curahsawo there are 6 types of Uca rosea, Uca lactea, vocans Uca, Uca perplexa, dussumieri Uca, Uca demani. The highest density of crabs is Uca perplexa as much as 16 ind/m2, the lowest type of Uca demani 4 ind/m2. Value diversity fiddler crabs in mangrove ecosystem Sawo relatively standart is 1,56. The value of existing dominance is 0,96. Index violin crab distribution patterns in the Mangrove Ecosystem Munitions Sawo is uniform for Uca lactea, Uca vocans, Uca dussumieri , Uca demani and clumped to Uca rosea and Uca perplexa. The result of the spread of fiddler crab to the type of soil texture is very visible on the Uca perplexa since spread across all points of soil sampling with the number 6 ind/m2 to 16 ind/m2 in the texture of clay and sandy loam.

Abstract

Riparian vegetation has an important role in maintaining water stability, one of which is the river. This study aims to describe the structure of riparian vegetation so that its implications can be seen for the conditions of rainbow arfak habitat on the Nimbai River. The study was conducted in three forest types, namely primary riparia forest, secondary riparia forest and open riparia forest. Sample collection of riparian vegetation was carried out by purposive sampling using sample plots. Plots measuring 2 m x 2 m are used to sample seedling and understorey growth, plots measuring 5 m x 5 m for growth at the stake level, while plots measuring 10 m x 10 m and 20 m x 20 m, for growth of pole and tree levels respectively. The identification results obtained a total of 35 species of understorey and 51 tree-level plants in all three types of riparian forests. Based on the analysis of vegetation structure, it is known that the condition of primary riparia forest and secondary riparian forest still relatively supports the life of arfak rainbow fish compared to open riparian forest. Higher tree level density associated with canopy cover which has implications for the temperature of the water to be colder and less fluctuating, input larger litter into the food chain in the river, and hold suspended particles into the river. Also, the function of riparian vegetation in spawning activities, substrate attaching eggs and nursery habitat for arfak rainbow fish larvae. The results of this study indicate the importance of riparian vegetation structure on the condition of rainbow arfak fish habitat. An understanding of the structure of vegetation is also a basic information for efforts to rehabilitate this endemic fish habitat to maintain the existence of a natural population.
