CONDITION OF PHYSIOLOGY FISH TILAPIA (OREOCHROMIS NILOTICUS) ARREST IN THE PROCESS OF USING TOOLS TO CAPTURE ACTIVELY MONITORED ELECTROCARDIOGRAPH (ECG)
(2013-07-31) Armen, Wahyudi; Nofrizal; Isnaniah
The research was conducted in March 2013 with the object of Tilapia (Oreochromis niloticus). The research objects are counted by the number of heartbeats different current treatments. The purpose of this study was to determine the heart rate of tilapia (Oreochromis niloticus), a basic knowledge of predicting the rate of metabolism and respiration and heart rate also determine the activity of tilapia at different swimming speeds, in the process of catching up with the use of active fishing gear. The higher the flow rate used in tilapia fishes the heart rate up, and seen in the relative heart rate ranging from (1.1 to 3.78), a portrait that fish require a lot of energy so that the fish is also increasing the body's metabolisme.

(2013-07-31) Ririantika, Wenny; Syaifuddin; Syaifuddin
The material strength of shipbuilders is one of the factors that support the quality of the ships, the better quality of ingredients, more qualified ship created. This research aimed to find out whether influence of composition of variation of strength of materials. This study aims to: (1) to find out there is the influence of variation of laminated fiber on tensile strength and press the fiberglass, (2) to determine the variations in the composition of fibres which are most suitable for use as layers of the hull. This research uses a variation of the 4 specimens, i.e. the specimen 1 (WR-WR-WR-Mat-Mat-Mat), specimen 2 (WR-Mat-WR-WR-Mat-Mat),specimen 3 (WR-Mat-Mat-Mat-WR-WR) and specimen 4 (Mat-WR-WR-WR-Mat-Mat) using survey methods, laboratory testing method (test tensile and bending test), methods of descriptive statistics and test variants in one direction (one way ANOVA). The results of this study indicate that the specimen with the variations in fiber WR-Mat-Mat-Mat-WR-WR (specimen 3) tensile strength value the average voltage is greater (11.94 N/mm2) than any other fiber variation (specimens 1, 2, 4), the variations in fiber WR-WR-WR-Mat-Mat-Mat (specimen 1) tensile strain strength value on average bigger (3,245 N/mm2) than any other fiber variation (specimens 2, 3, 4) and the variations in fiber Mat-WR-WR-WR-Mat-Mat (specimen 4) bending strength has a value of voltage the greater average (32,05 N/mm2) than any other fiber variation (specimens 1, 2,3).

(2013-07-03) yandra, Dedi
For purpose to examine and compare efectiveness of the PVC and traditional trap for catching ell (M. Albus). Experimental fishing was conducted in field rice as fishing ground of the ell. Five unit PVC and tradistional traps repectively were set in the fishing ground randomly. The method that used for this study is experimental fishing.The fishing catches data were analized by t-student. The result show that the traditional trap more effective than PVC traps (P < 0.05), which the total of traditional trap fihing catches was 156 individuals and the PVC trap was 88 individuals. The comparisson of fishing catches of the traditional and PVC trap will be deeply discussed in this paper.

(2013-06-26) Harefa, Darno
For purpose is to know the visibility distance of fishing gear’s material with different color (white, red, yellow and blue) in the waters, it expected can be applied to the fishing gear’s construction to obtain the best color material for fishing gear performance. The monofilament 2 mm in diameter and multifilament 10 mm in diameter was tied at wire frame (1 x 1 m). The wire frame was shot in 1-5 meter water depth with the distance 0.5-2 meter by underwater digital camera (Canon G11). The photograph result show that the visibility distances of monofilament was 0.5 meter in the waters. Meanwhile, the visibility distance of red and blue multifilament was 1 meter. However, the visibility distance of white and yellow multifilament was 1.5 meters. Furthermore, the effect of environment factors on the visibility distance of multifilament and monofilament were discussed in this paper.

STUDY ON THE MATERIAL OF OCTOPUS TRAP AS SUBSITUTION MATERIAL SNAIL SHELL AT SEI NAGALAWAN VILLAGE, NORT SUMATERA
(2013-06-07) Zamharir
Purpose of this study is to invent a alternative material for octopus trap, which subsituted snail shell. The experimental fishing was conducted to find out the best material for octopus trap. Two treatments was used in this experiment, which was ceramic and coconut shell. While, the snail sheel as a control. The ceramic, coconut shell and snail shell trap was set randomly at main line. Those were setting 3-4 miles from the coastal line, with 4-5 meters water depth. The result show that the fishing cacthes of snail shell trap was highest than ceramic and coconut snail trap, which was 12 induviduals for snail shell trap, 6 individuals for ceramic traps and 2 individuals for coconut shell traps. Efectivity of snail shell trap was influenced due to its highest rupture resistance in the waters than ceramic than coconut shell and had proporsional demension to octopus size as main fishing target.

IDENTIFIKASI METODE PENANGKAPAN IKAN KURAU DI DESA TELUK PAMBANG KECAMATAN BANTAN KABUPATEN BENGKALIS PROVINSI RIAU
(2013-01-18) Wati
The study was conducted on July 03-13, 2012 in Teluk Pambang Village Bantan District Bengkalis Regency of Riau Province. The purpose of this study was soul to determine the effective method for catching Kurau fish. The effective where method in based on indicator as the indicated such as size of caught fish, how the fish caught by net, fish behavior, and number of catches of each fishing method and beside to investigate whether those methods is ecofriendly or not refer to FAO 1995 regulation. Gill net and mini long line can caught kurau fish, gill net caught much more fishes than mini long line as gill net method block the fish schoal movement whereas the mini long line depead on alfaction organ of fish in find the bait position as influence of the currents. The size of bait can influence the alluring of fish to bite. Based on FAO 1995 regulation that longline fishing gear and gill net can be concluded as the environmentally friendly fishing gears.

The method used in this research is a survey method and conducted for 9 days where every day in data capture sondong 1 unit of fishing boats were chosen purposively. The purpose of this study was to determine the level of efficiency of the charging time to time supplies sondong fishing boat mooring in fish landing base (PPI) Dumai and the things that influence it. The results of research that the efficiency of the charging time by fishing supplies gear sondong ranged from 44.29% to 71.15% and classified as less efficient. This is indicated by the average charging time efficiency provisions of 57.58%. The factors that have a strong relationship is the amount of time wasted, the amount of fuel supplies, the age of the perpetrator charger supplies, fishing path length, the amount of fresh water supplies, the amount of time wasted. Factors that have weak ties that supplies the amount of ice, the amount of GT, and the count of fishing trip.
