Abstract: Tulisan ini menjelaskan pengaruh pemusatan cahaya petromaks terhadap efektivitas bagan. Penelitian dilakukan dengan mengoperasikan 3 jenis reflektor, yaitu reflektor standar dan 2 reflektor pirarnid yang diwarnai putih dan perak. Iluminasi cahaya di ukur pada kedalaman 1-8 m. Hasilnya adalah iluminasi cahaya semakin berkurang dengan bertambahnya kedalaman perairan. Reflektor peTak memberikan iluminasi cahaya dan hasi1 tangkapan organisma fototaksis positif tertinggi. Ini diikuti oleh reflektor putih dan standar. Waktu pengoperasian bagan terbaik didapatkan pada interval waktu 19.00-22.00.
This paper describes The effect of light concentration ofpetromax on lift net effectivity. The experiment was carried out by operating 3 kinds ofreflectors on lift net. Those reflectors were a standard reflector, white-and silver-colored pyramid reflectors. Light illumination was measured at 1 to 8 m depth. The result showed that light illumination decrease with the increasing of water depth. Lift net using silver-colored pyramid reflector produced the highest light illumination and the biggest catch ofpositive phototaxis organisms followed by lift net using white-colored pyramid reflector and standard reflector. The best operation time of lift net was obtained between 7pm to 10 pm.
