Metode penelitian yang digunakan adalah survey. Data hasil tangkapan ditabulasikan dan dianalisis secara deskriptif. Hasil penelitian menunjukkan 3 jenis bagan memiliki ciri khas masing-masing. Bagan apung memiliki ukuran kapal pengangkut 8 GT. Ukuran kapal bagan badak 8 GT dan bagan cungkil 21 GT. Hasil tangkapan utama dari bagan apung tercatat 8 jenis ikan dimana HTU tertinggi yaitu teri 793,8 kg dan HTS nya tembang 348,8 kg. Bagan badak tercatat mendapatkan 6 jenis ikan dengan HTU tertinggi teri 887 kg dan HTS nya tembang 420,2 kg. Sedangkan bagan cungkil tercatat 6 jenis ikan terdiri dari HTU tertinggi teri 1.008,2 kg dan HTS nya tembang 596,5 kg. Produktivitas bagan cungkil sebesar 688,7 kg/trip, bagan apung 69,74 kg/trip dan bagan badak 230,05 kg/trip., Performance of 3 lift net fishing units has been carried out in Bandar Lampung. The research objective are to describe the fishing unit the three types of and to compare the catch composition and weight of the catch from each fishing unit. The research method used was a survey. The catch data was tabulated and analyzed descriptively. The results showed that 3 types of charts have their own characteristics. The floating chart has a ship size of 8 GT and boat lift net ship size 8 GT. Cungkil lift net have a boat 21 GT. The main catch from floating lift net was recorded 8 fish species where the highest target catch (HTU) was Anchovies 793.8 kg and by catch of sardine 348.8 kg. Boat lift net was recorded to get 6 species of fish with the highest HTU of anchovies 887 kg and by catch of sardine 420.2 kg. Meanwhile, cungkil lift net have recorded 6 species of fish, consisting of the highest HTU for anchovy 1,008.2 kg and by catch of sardine 596.5 kg. The productivity of cungkil lift net is 688.7 kg/trip, floating lift net and bagan badak is 69.74 kg/trip and 230.05kg/trip respectively.

Judul: Penggunaan Kombinasi Atraktor Rumpon dan Umpan Vertikal terhadap Hasil Tangkapan Bagan Apung di Palabuhanratu
Abstrak: Penelitian penggunaan kombinasi atraktor rumpon dan umpan vertikal berbahan ikan rucah dan larutan cumi-cumi untuk memperkuat fungsi cahaya lampu dalam memikat dan mengumpulkan ikan agar lebih efektif. Tujuan penelitian untuk membandingkan komposisi hasil tangkapan bagan apung perlakuan dan kontrol, menentukan pengaruh penggunaan atraktor rumpon dan umpan vertikal terhadap jumlah total hasil tangkapan, menentukan frekuensi hauling, dan menentukan produktivitas bagan apung perlakuan dan kontrol. Penelitian ini menggunakan metode eksperimental fishing dengan mengikuti operasi penangkapan selama 20 trip. Hasil tangkapan pada bagan apung perlakuan sebesar 964,2 kg dan bagan apung kontrol sebesar 445,4 kg dengan rata-rata berat total hasil tangkapan pada bagan apung perlakuan yaitu 48,2±13,2 sedangkan kontrol yaitu 22,2±3,1. Hasil tangkapan dominan pada penelitian ini adalah semar (Mene maculata), tembang (Sardinella gibbosa), pepetek (Leiognathus equulus), teri (Stelephorus sp.), dan cumi (Loligo sp.). Penggunaan atraktor rumpon dan umpan vertikal berpengaruh nyata terhadap hasil tangkapan bagan apung dan frekuensi hauling bagan apung perlakuan berjumlah 110 kali, sedangkan pada bagan apung kontrol yang hanya berjumlah 76 kali. Penggunaan umpan membantu kenaikan persentase produksi tangkapan bagan apung perlakuan meningkat sebesar 116,5% jika dibandingkan dengan bagan apung kontrol. Produktivitas bagan apung perlakuan sebesar 48 kg/trip dan 8,3 kg/haul, sedangkan kontrol yaitu 22,3 kg/trip dan 5,0 kg/haul., The study used a combination of FADs attractors and vertical baits made from trash fish and squid solution to strengthen the function of light in attracting and gathering fish to make it more effective. This study aimed to compare the composition of the catch controlled variable (commercial floating lift nets) and lift net with vertical baits, determine the effect of using FADs and vertical baits attractors on the total catch, determine to haul frequency of the lift net, and determine the productivity of treatment and control lift net. The research used experimental fishing methods by following fishing operations for 20 trips. The catch on the treated lift net was 964,2 kg, and the control lift net was 445,4 kg, with the average total weight of the catch on the treated lift net being 48,2±13,2 while the control was 22,2±3,1. The dominant catches in this study were moonfish (Mene maculata), gold stripe sardinella (Sardinella gibbosa), ponyfish (Leiognathus equulus), anchovy (Stolepthorus sp.), and squid (Loligo sp.). Using FADs and vertical bait attractors significantly affected the total catch and hauling frequency with 110, while in the controlled variable, which is only 76 times. The use of bait helped increase the percentage of production of the treated lift net by 116,5% compared to the control lift net. The productivity of the treated lift net was 48 kg/trip and 8.3 kg/haul, while the control was 22.3 kg/trip and 5.0 kg/haul.

Judul: Sintesis Flavon dari Fenol dan Benzoil Klorida
Abstrak: Flavone is a class of flavonoid, commonly found in plants with wide bioactivity spectrum. A widely used flavone synthesis route is through acidcatalyzed oxidative cyclization of β-diketone. In this study, unsubstituted flavone had been synthesized via 5-step from phenol, with 22% yield and successfully increased the yield of previous study on Fries rearrangement of phenyl acetate and benzoylation of o-HAP steps. Phenol was acetylated resulting 93% phenyl acetate. AlCl3-catalyzed Fries rearrangement in 1.5 hour and at 120 °C converted phenyl acetate into o-hydroxyacetophenone (o-HAP) with 40% yield. AlCl3 as catalyst produced o-HAP with higher and reproducible yield compared with BF3·Et2O and ZnCl2. Benzoylation of o-HAP followed by Baker-Venkataraman rearrangement of the ester product using KOH in dried pyridine produced β-diketone 1-(2- hydroxyphenyl)-3-phenylpropane-1,3-dione. The yield of ester and β-diketone were 71% and 85%, respectively. Finally, oxidative cyclization of β-diketone with sulphuric acid as catalyst produced 99% of flavone. The flavone product had been characterized spectroscopically and its melting point as well.
