Abstract

ABSTRAKThe purpose of this study was to know  the Contribution Of The Belawan Ocean Fishing Port to the Fisheries Sector Of  North Sumatera Province. By using  survey method, this research was conducted in May 2018. To find out the value of the contribution of the Belawan Ocean Fishing Port to The Fisheries Sector Of North Sumatera Province which was datermined by knowing the percentage (%), the fishing catch data on Belawan Ocean Fishing Port were compared with the fishing catch data in North Sumatera Province. Based on data from the Belawan Ocean Fishing Port and the North Sumatera Provincial Fisheries service from 2012-2016 shows that the role of the Belawan Ocean Fishing Port in the North Sumatera Province Fisheries Sector in terms of the number of Fishing Gear, Fishing Fleet, Number Of Fisherman, Fisheries Production, And Production Value as well as retribution is moderate because the contribution value is between 33,4% to 66.6% According to criteria (Siregar 2006).Keywords :Contribution, fishing port, fisheries sector.

Abstract

ABSTRACTThe research was conducted in March-April 2018 which was held in Nagari Tiku V Jorong, Tanjung Mutiara Subdistrict, Agam Regency. The goal of theresearch was to see the changes in the physical properties of the mesh on the trammel net post-operation fishing gear that is after being used for 0, 1 month, 6 months and 12 months, so that the trammel net fishing gear net is known. The method used in this study is the survey method which is to collect data and materials at the research location, then proceed with a direct experiment method or experiment in the laboratory of the Department of Fisheries Resource Utilization, Riau University. The results of this research indicate that the breaking load on the net both inner net and outer net has decreased over time, this can be seen with the BL equation (Breaking Load) = -0.0044 t + 0.1974 for the inner net and BL (Breaking Load) = -0.0231t + 0.7547 for the outer net. In the elongation value also decreased with the equation E (elongation) = -2.8816t + 26.117 for inner net and E (elongation) = -1.6231t + 54.01 for the outer net. Increased use of age causes the size of the mesh to increase but not drastically. Whereas for node stability there is no node shift because the net breaks at the foot of the thread instead of the loose node. Based on this study it can be concluded that the technical age of the net is 12 months. Keywords : mesh size, physical properties, trammel net, usage age.

This research was conducted in April to May 2018. This study aims to calculate the density of Pseudomonas sp.bacteriaand heterotrophic bacteria in Dumai sea waters, comparison of the desity of Pseudomonas sp. bacteria to heterotrophic bacteria at each station and the resistance of Pseudomonas sp. to antibiotics. The result showed that densityPseudomonas sp. ranged from 2.25 x 105- 6.08 x 105 CFU/ml. The highest number of Pseudomonas sp.at station 1 and lowest at station 5. The total number of heterotrophic bacteria ranged from 7.37 x 106 - 10.38 x 106 CFU/ml. The highest number of heterotrophic bacteria at station 4 and the lowest at station 5.The highest percentage rasioof density of Pseudomonas sp. bacteri to heterotrophic bacteria was in station 1 (6.26%) and the lowest was in station 4 (2.86%). The results of isolation of bacteria obtained 25 pure isolates and tested for bacterial resistance to antobiotics. Results of isolation bacteria obtained 25 pure isolates and tested the resistance ofPseudomonassp. bacteriato antibiotics.Chloramphenicolantibiotic test results showed 2 isolates classified as sensitive with inhibition zone of 21,3 – 21,9 mm, 1 isolate including resistance with 9,7 mm inhibition zone, with a 22 isolates classified as intermediate with a inhibition zone of 9.7 – 19.6 mm. Two other antibiotics Penicillin and Isoniazid, all bacterial isolates were resistant with the inhibition zone range from 1.2 – 4.6 mm and 1 – 2.8 mm respectively Keyword: Density, Pseuomonas sp.,Heterotrophic Bacteria, Antibiotics

Abstract

 ABSTRACT  Functional facilities are complementary to basic facilities to facilitate work. Providing services in fishing ports and adding value to all work activities in the port area so that optimal port benefits and uses can be achieved. The purpose of this study was to determine the utilization rate of various functional facilities found in the Cilacap Ocean Fisheries Port. This research was conducted in December 2017 in the Cilacap PPS, Cilacap Regency, Central Java Province, using a descriptive method. The results showed that there were a number of functional facilities in the Cilacap PPS which were still utilized including port offices, workshops and docks, water tanks, electricity networks, gas stations, fish processing, tool and fishing material kiosks, generator houses and beacon lights. While those that are not utilized are fish processing and mini plan. Based on the results of the analysis that has been done, the utilization rate of freshwater tank facilities in Cilacap PPS is 34.6% and the type of utilization is classified as very underutilized. Furthermore, the utilization of the BBM tank facility in the Cilacap PPS is 23.2% of which the type of utilization is classified as not utilized.Keywords: Meskom Village, Gombang, Study of Fishing Ground gombang.

Abstract

AbtrakThis research was conducted in May 2018 in the Mangrove Ecosystems at industrial and non-industrial areas of Sungai Sembilan District, Dumai City, which aimed to determine the morphometrics  and the lenght-weight relationship of C. cingulata and L. Melanostoma.Survey method was appled by using line transect at 2 stations, namely in the industrial area (PT. Ivo mas, PT. Sinar Mas, PT. Energi Sejahtera Mas) and non industrial area (Sungai Teras). The results showed that the morphometrics of C.cingulata and L. melanostoma at each station had different sizes. In industrial area,C. cingulatahas larger and wider than larger of size non industrial zone. On the other hand in the non industrial area,L. melanostomahas larger and wider than larger  of size industrial zone. The relationship between length and weight of C.cingulata infor industri at area is negative allometric, but  it was positive allometric for non industrial zone. Meanwhile the length and weight of L.melanostoma in both areas are negative allometric and they have strong correlation values (r= 0,99 dan 1). Keywords: Morphometrics, Cerithidea cingulata, Littoraria melanostoma, Dumai

AbstractPharella acutidens clam is a bivalve lives in mangrove ecosystem , which is one of protein source for Rupats’ people. This research was conducted in Maret 2018 located at the mangrove forest of Sungai Cingam Village, Rupat Sub District, Bengkalis Regency. This research was aimed to determine the habitat characteristics, density and distribution patterns of P. acutidens . It used survey method and sampling location determined by purposive sampling. Measurement of water quality was done by in situ and ex situ which consist of physics and chemical parameters. Habitat characteristicsof P. acutidens was muddy sand,  and sandy mud . Sediment organic matter was high 10,60-14.85%. The water quality parameters were still support for the life of the P. acutidens. The average density was 1,8-4.2 ind/m2. The highest density was in middle zone and the lowest in upper zoneof the Intertidal. The distribution pattern was grouping. While highest size of individual P.acutidens found 7cm.Keyword: Habitat Characteristics, Density, Distribution Patterns, P. acutidens.
