Judul: The Performance of Lift Net Fisheries at Bandar Lampung Lempasing Coastal Fishing Port
Abstrak: Keragaan terhadap 3unit penangkapan bagan telah dilakukan di Bandar lampung. Tujuan penelitian untuk mendeskripsikan alat tangkap ke tiga unit bagan dan mengetahui perbandingan komposisi dan bobot hasil tangkapan dari setiap unit bagan. 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: Efektivitas Lampu Tabung pada Perikanan Bagan
Abstrak: The objective of this research was to determine the effectiveness of tubular lamp construction to attract organisms in floating bamboo lift net and the best time interval to operate floating bamboo lift net. Lamp construction consisted of standard lamp, lamp with reflector, underwater lamp, and surface lamp without reflector as control. The research was started while floating lift net using lamps without reflector at 07.00 pm to 10.00 pm; the lamp with reflector between 10.00 pm to 01.00 am; and underwater lamp between 01.00 am to 04.00 am. The lamp operation series was changed at each floating bamboo lift net operation. Every lamp construction was operated 1-3 times in a time interval. Collected data were light illumination of each lamp construction in water, and weight and species composition of caught organisms. Data were showed on tables and graphs. Data analysis used descriptive comparative methods. The result of this research indicated that tubular lamp construction with reflector and underwater lamp had the best distribution light on floating bamboo lift net operation. Light penetration of both lamps were about 9 and 10 m, respectively. The standard tubular lamp spread in all direction with maximum light penetration of 6 m. Time interval between 07.00 pm to 10.00 pm and 01.00 am to 04.00 am were the effective time to catch organisms. Both time intervals produced 119.8 kg and 125.2 kg. While, time interval between 10.00 pm to 01.00 am was only 41.3 kg. The organisms that was caught by floating bamboo lift net consisted of 4 positive phototaxis organisms and 4 predator organisms. The positive phototaxis organisms were mackerel, indian mackerel, anchovy, and trasi shrimp. While the predator were hairtails, silver pomfret, cuttlefish, and little tuna. Lift net with underwater lamp caught heavier organisms than those tubular lamp with reflector and standard lamp, i.e. 151,7 kg, 95,9 kg and 65,6 kg in weight.

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.
