Judul: Uji Coba Rumpon Elektronik pada Alat Tangkap Bagan di Pulau Lancang, Kepulauan Seribu, Jakarta
Abstrak: Electronics FADs is an innovative fishing tools that have the same function as in the general FADs to attract and collect fish. The trial of electronic FADs was did at liftnet gear, in purpose to see the performance of these tools. Effectiveness of use electronic FADs analysis from catch harvest. Electronic FADs has attractor a light (LED, 5 Watts) and sound (10-1000 Hz, 1-20 kHz dan 20-100 kHz) with a voltage source of 12 volt battery. Installation of electronic FADs in the trial following the existing catch method in the liftnet. Based on catches, electronic FADs managed to collect an average of 4.6 kg if time installation is an hour, and collect an average of 4.07 kg if time installation is 30 minute. Electronic FADs work well, attractor is able to function throughout the trial and managed to collect the fish, but when compared the effectiveness of the catch to the liftnet, then the use of electronic FADs in the liftnet is still not effective. Suggestions for improving the effectiveness of electronic FADs catch on the liftnet is increase the intensity and power on light attractor, and deeper study of the sounds frequency which response by fish
