Judul: Reflector Utilization with Different Angles: An Effort to Increase Fish Catch on Lift Net in Kao Bay, North Halmahera
Abstrak: Technology development of light fishing using incandesent light bulb on a lift net boat in Kao Bay was expected to increase the fish catch. But in fact, when light fishing was operated on the lift net, it remain not have the maximum catch. This problem was caused due to the limited fishing knowledge of the fishermen in utilizing the light towards the targeted fish behaviour. Fishing effort that has been done by the fishermen in Kao Bay in order to maximize the light utilization was by covering the upper part of the bulb with various types of bowl or pan. The goal was to focus the illumination to the lift net. This was done by them without scientific study whereas centralizing scattered light must be done with theoretical calculation and scientific evidence. This bulb cover utilization usually applied in every fishing operation either in bright or dark moon condition. This research objective was to fix the bulb cover by equipping it with a layer of reflector. The illumination was directed to the lift net at two and five meter distance. As a result, each reflector here the opening angle αr23,3° and αr32,6°. The objective of this research was to determine the organism gathering speed below the covered and reflectored light bulb during the hauling in the full and dark moon period, to find out the light bulb reflector which might give the most catch result during the squids and fish kinds hauling and to determine the effective hauling time during the squids and fish kinds hauling operation. Research phases were conducted in two kinds i.e. the laboratory and field scale. At the laboratory research, the reflector was designed and fabricated. Furthermore, the light intensity measurement towards the covered bulbs -- referred as standard cover-- and reflector. Research continued by testing all three kinds of cover on the field by utilizing three lift net boat from local fishermen. Lift net boat that equipped with standard bulb cover was served as control, while the other two reflectors was utilized as treatment. In the third test the bulb cover was used as experimental method. The operation of lift net was conducted in 24 nights which was divided into two moon periods. During the first 14 nights or bright moon period, lift net was focused to catch squids. Hauling time was done twice between 20.00-01.00 WIT and 01.00-05.00 WIT. The lift net operation that was used for catching fish kinds performed on the following 10 nights in dark moon period. Two hauling times were set between 20.00-00.00 WIT and 00.00-05.00 WIT. The fish behaviour below the lift net was observed with visually and acoustically in every lift net operation. Visual observation was done towards existing organisms on the water surface to a depth of two meter. Meanwhile the acoustic observation was conducted to observe the organism activity at the depth of more than two meter. Result was analyzed in descriptive comparative way based on the light bulb cover type. The catch result that was hauled by the lift net was displayed in the form of numbers

Judul: Application of LED (Light Emitting Diode) Lamp in Stationary Lift Net Operation
Abstrak: The success of fishing operations with lift net is highly dependent on light lamp. Light function here is as a decoy fish to come. Installation of the light source on the net will cause the fish that are positive fototaksis -- who is interested in catching the light and into the goal chart-- will at the bottom of the net. Net which has sunk will easily catch schooling of fish that congregate on it. The purpose of this study is (1) Getting the most effective construction lights to catch fishing with at stationary lift net; (2) Determine composition of catches stationary lift net that uses LED lights that hanging, dipped in water and fluorescent lamp; and (3) Determine the most effective time of the catch in the operation on stationary lift net. The method used is experimental fishing. The study begins with the design and measure of energy saving lamps, the next trial fishing conducted with the help of lights that have been made. Catch data for each treatment were analyzed descriptive comparative to compare is capability catch and efficiency of the lamp that designed and fluorescent lamp by the fishermen. Furthermore, to see the effect of the use of submersible lamps, hanging lamps, and fluorescent lamp (fisherman) at different times of the statistical analysis of the catch completely randomized design (RAL). Before the RAL test, the data was tested using normality test by analysis Klomogrov Smirnov. If the normal spread of data, then the parametric statistical tests will be done completely randomized design (RAL), but if not, will be tested non-parametric statistical Kruskal-Wallis. These results indicate that construction submersible LED lights produce a catch weight of 287.6 kg or higher than the fluorescent lamp construction 238.3 kg and 209.5 kg LED chandelier. Submersible LED lights produces 11 types of organisms catches consisting of HTU 212 kg and HTS 74.8 kg, LED hanging lamp 10 types of organisms (148.9 kg and 60.0 HTS) and fluorescent lamp result 6 tipe organisms (227.5 kg HTU and 10.8 kg HTS). Time to step on the effective operation of the third lamp of stationary lift net is between the hours of 18:00 to 21:00 that produce (289.5 kg), while 21.00-24.00 hrs (166.8 kg), 3:00 to 6:00 pm (146.3 kg) and 00:00 to 3:00 pm (134.4 kg).
