Abstract

Hand line is the simplest and easy fishing gear used by mostly tuna fisherman. These study goals are to see the development of production and productivity tuna catch by hand line of tuna fishing boat at Mawali village. The result shown that the production of tuna increased from 2011 and reached the top on 2013, and then decreased until 2015. Furthermore, the productivity of tuna fishing boats since 2011 to 2015 indicated only three boats are good and the others found unproductively. The decline of tuna productivities occurred due to the government policy to reduce the labor of foreign, especially in the field of capture fisheries.Keyword : tuna, hand line, production, productivity ABSTRAKHand line atau pancing ulur merupakan pancing yang sangat sederhana dan mudah digunakan oleh kebanyakan nelayan.  Penelitian ini bertujuan untuk melihat perkembangan produksi dan produktivitas hasil tangkapan kapal tuna yang menggunakan alat pancing hand line di Kelurahan Mawali.  Produksi ikan tuna mengalami peningkatan dari tahun 2011 hingga tahun 2013, dan selanjutnya mengalami penurunan hingga tahun 2015. Selanjutnya, produktivitas kapal tuna hand line sejak 2011 sampai 2015 menunjukkan hanya terdapat tiga kapal yang produktivitasnya baik dan yang lainnya menemukan produktivitas yang tidak baik. Penurunan produksi ikan tuna terjadi karena kebijakan pemerintah yang mengurangi tenaga kerja asing, terutama di bidang perikanan tangkap.Kata kunci : tuna, pancing ulur, produksi, produktivitas

Abstract

Binahong leaves are one of natural product to be used to treat the diseaseof living organisme due to having secondary metabolite to show antibacterialactivity. The purpose of this research was to study secondary metabolite ofBinahong leaves of which showing antibacterial, to analysis effectivity ofantibacterial Binahong leaves extract to inhibit growth of bacteria Aeromonashydrophila. An experimental laboratory with six treatments and three replicationsfor in vitro was tested. A paper disc soaked in a solution of Binahong leavesextract was used for in vitro at a concentration of 0% (w/v); 0,2%; 0,4%; 0,6%;0,8%; positive control (Oxytetracycline). In vitro test showed that Binahongleaves extract inhibited the growth of bacteria A. hydrophila with a inhibitionarea around the paper disc. Diameter Inhibition area that formed was 0 mm ( 0 %negative control ), 8.4 mm (0.2 %), 9.4 mm (0.4 %), 10.5 mm (0.6 % ) ; 11 , 9 mm(0.8 % ), 27.5 mm (positive control). The increase concentration of Binahongleaves extract enhanced the growth inhibition area. Phytochemical screening ofBinahong leaves extract showed that the extracts contained flavonoid, phenol,saponin, alkaloid, steroid/triterpenoid.Keywords : Binahong leaves, Aeromonas hydrophila, flavonoid, phenol, saponin,alkaloid, triterpenoid, ? ?sitosterol

Abstract

The Purpose of Lake Toba were very diverse and required water qualityand fulled certain requirements. Otherwise, the used of the lake for the variousactivities of the society also gave impact to water quality degradation. Thisresearch were conducted from May to July 2013 in Lake Toba. This research usedPurpossive Random Sampling. There were 3 locations. Station I: Ajibata area,Station II: Haranggaol area and Station III: Porsea as the outlet of Lake Toba.Sampling activities were conducted once/month. This research aimed to knewheavy metal consentrate of Lead (Pb) and Copper (Cu) in water and sediment.This results showed indicated chemical physics parameter of Lake Tobastilled in the normal range. Concentrations of copper (Cu) in the water column ateach station in sequence 0.027 mg/l, 0.025 mg/l, 0.033 mg/l and the concentrationof lead metal (Pb) in the water column 0.039 mg/l, 0.014 mg/l, 0.029 mg/l. Whilemetal concentrations of copper (Cu) in sediments at each station in sequence1.092 mg/kg, 2.85 mg/kg, and 2.483 mg/kg and the concentration of lead metal(Pb) of 3,058 mg/kg, 3.592 mg/kg and 2,833 mg/kg.

The objective of the research are to determine the macrozoobenthos and its related to chemical and physical parameters. The method used in this research is purposive sampling where river waters Bingai used as a research location. Based on the research was found 3 classes and 7 genusses of macrozoobenthos in waters of River Bingai, West Binjai Subdistrict. The gastropods was the most abundance in the river. Index of species diversity showed lower value that means water quality was moderate. The evenness index and dominan index was coherent to water quality condition.Keyword : Macrozoobenthos Community, Water Quality, River Bingai.

Abstract

The current of aquaculture development is not accompanied with sufficient fry supply due to some constraints and difficulties in the supply of life food. The life food culture Nannochloropsis sp. by using vermicompost fertilizer has never been used before, while the vermicompost contains nutrient required by cells of Nannochloropsis sp. to support the growth and reproductions. The purpose of this research is to know the influence of the vermicompost fertilizer treatments on the abundance of the cells Nannochloropsis sp. and how much the optimum concentration. This research was conducted in Balai Budidaya Air Payau (BBAP) Ujung Batee, Banda Aceh. The threatment of life food culture was done with 10 liters volume of water about 10 days. Parameter were observed are the growth of abundance Nannochloropsis sp. cells and quality of water. The used by completely randomized design with 5 treatments and 3 times repeatitions. Those 5 treatments are as follows the control treatment with technical fertilizer, 0 ppm (without treatment vermicompost), 50 ppm, 100 ppm, and 150 ppm. The treatments vermicompost fertilizer is effect on the abundance Nannochloropsis sp., the optimum concentration 100 ppm and the medium abundance in day 5 with density 6.895.000 cells/ml.Keywords : Nannochloropsis sp., vermikompost, abundance

Abstract

Botia (Chromobotia macracanthus) is a freshwater fish that are having economic value is important because it has high sale value, especially in the ornamental fish market in North Sumatra. Life food is an important factor in the cultivation of ornamental fish. The research was conducted to determine the effect of feeding Tubifex worms (Tubifex sp.) on the growth performance and survival rate of Botia larvae. Tubifex worm culture do by using a wooden box with a recirculation system and the maintenance of Botia larvae done with volume 72 liter aquarium in a closed room.Experimental design using a completely randomized design with 5 treatments with 3 replications, as follows; 1) The Tubifex worms culture given chicken manure fermentation, 2) The Tubifex worms culture given cow manure fermentation, 3) The Tubifex worms culture given sheep dung fermentation, 4) Tubifex without treatment, 5) Pellet ornamental fish. The survival rate was 100 % in each treatments. Feeding the Tubifex worms are cultured with sheep dung fermentation gives the best results on the survival rate (SR), the absolute length (L), absolute weight (W), and daily growth rate (GR), respectively 1.02 cm, 0.91 g, and 2.57% for 30 days of maintenance.Keywords: Artificial feed, Botia, Tubifex.
