Hairtail fishing (Trichiurus sp) in Palabuhanratu using handline is highly dependent on fishing bait. The bait which is usually used by fishermen is natural bait which is a piece of trash fish. The purpose of this research is to find bait alternative as a replacement of natural bait for hairtail fishing. Three type of baits used in this research were natural bait as a control, artificial bait and combination between natural and artificial bait. The aims of this research are to prove that artificial baits can increas the catch and to determine the effective time for handline fishing operations. Three kinds of baits were operated at the same time on a single unit of handline fishing boats for 22 days.The research using comparative descriptive analysis and statistical analysis completely randomized design (RAL). The results showed that combination bait can capture 453 hairtails or 52% of the total catch which is more than artificial bait that catch 223 hairtails 25% and natural bait that catch 203 hairtails 23%. The best time of the capture is between 05:00 am to 07:00 am that catch 379 hairtail or 43% of the total catch, and then at 07.00 am to 09:00 am and 09:00 am to 11:00 am, each captured 298 fish 34%, and 202 fish 23%.
Bagan perahu merupakan alat tangkap yang paling populer di Desa Lhokseudu Kecamatan Leupung Kabupaten Aceh Besar. Nelayan bagan perahu menggunakan lampu neon putih yang dioperasikan di atas permukaan air sebagai pemikat ikan pada saat operasi penangkapan ikan. Beberapa penelitian telah membuktikan bahwa lampu celup bawah air bisa menghasilkan lebih banyak ikan tangkapan. Di sisi lain, perkembangan teknologi telah menemukan lampu LED (light emitting diode). Lampu LED bisa memancarkan cahaya yang lebih terang, dengan input energi lebih kecil dibandingkan dengan lampu neon. Penelitian ini bertujuan untuk mengetahui efektivitas lampu LED celup sebagai lampu hauling pada bagan perahu. Penelitian dilakukan di Desa Lhokseudu sebanyak 15 trip mulai 13 Mei hingga 13 Juni 2016. Pengumpulan data dilakukan dengan menggunakan metode experimental fishing menggunakan dua buah bagan perahu. Satu bagan perahu menggunakan lampu LED celup sebagai lampu hauling dan bagan perahu lainnya menggunakan lampu hauling nelayan sebagai bagan kontrol. Parameter yang diamati adalah berat hasil tangkapan per trip dari kedua bagan untuk dibandingkan. Penelitian ini menyimpulkan bahwa ikan dominan hasil tangkapan bagan perahu di Lhokseudu adalah Rastrelliger kanagurta, Selaroides sp, dan Sardinella sp. Efektivitas lampu hauling LED celup 132,09% lebih baik dari pada lampu hauling pada bagan kontrol. Hasil uji t pada total tangkapan menunjukkan perbedaan yang signifikan dengan nilai P = 1,8 × 10-3 (kurang dari 0,05) pada tingkat kepercayaan 95%.Kata kunci: bagan, lampu hauling, lampu LED celup, Lhokseudu.
