Judul: The difference of Type and Water Depth of Attractor Setting on Squid Egg Attachment
Abstrak: Squid represent marine resources that involves high economic value. Most intensive squid fishing season occurred at the spawning season where in this season most of squid has matured gonad. This activity make degradate squid amount in nature. Marine culture technology like breeding or hatchery need to balance squid fishing activity and to enhance stock of squid in nature. The hatchery needs squid egg supplied continuously. Attractor can be used to collect squid egg from nature. The squid egg collecting activity from nature can become additional activity or alternative job for fisherman. Based on this case, research was conducted on types and water depth differences of attractor setting on squid egg attachment. The research has been conducted in Mutiara Bay, Alor Regency, NTT Province for four months from 17 August 2005 to 18 December 2005. Aim of this research was to find out the effect of type and water depth differences of attractor setting on squid egg attachment and to determine what type and depth of attractor setting that suitable for squid lays their egg. Attractor was made from local materials like bamboo and palm tree fiber. The treatment design of this research used two types of attractors and three levels of water depth. The type of attractors were covered by goony sack and uncovered by goony sack. Setting difference of attractors were placed in surface (0-1 m), middle (2-3 m) and bottom (4-5 m) of coastal waters. Data was analysed by average test (t-test). The result of this research show that squids attach their eggs on the covered attractor by goony sack that placed in the bottom of coastal waters at 4 -5 m. The eggs hatched in 28 to 30 days.

Judul: Funcional Interaction of Squid (Loligo chinensis. Gray 1849) Egg Attachment on Atractor Squid Aggregate Device in Tuing Sea Bangka Regency
Abstrak: Numbers of armada and fishing gear modernisation are not accompanied by squid stock enrichment program. Atractor squid aggregate device is one of the efficient technology for squid stock enrichment program development in the future. Atractor squid aggregate device form and material recently are less applicative for fisherman condition in the remote area. Therefore atractor squid aggregate device model modified to become less complicated by using cheaper and easy to find material based on local potency in the area. This research was conducted in Tuing Sea, Bangka Regency, Bangka Belitung Province since October 2012 until June 2013 by using 12 units of atractor squid aggregate device. There are two type of squid aggregates devices in this research which are 6 units square form with wood material and 6 units cylindrical form made from used drum. Each atractor squid aggregate device drowned in 3 meter and 5 meter depth and monitored 5 times. The result of t-test show that time of monitoring factor and atractor squid aggregate device form are two factors which most influenced the squid eggs attachment to aggregate device. The result of research shows that squid eggs attach effectively to cylindrical form Squid aggregatee device, 3 meter depth and in November – Desember 2012. Monitoring in November-December 2012 was predicted as time of squid spawning in the study site because of many egg capsules of squid attached. Atractor squid aggregate device that cylindrical form was more enclosed and protected so squids prefer to attach their eggs than rumpon atractor that box form. During the five times monitoring of the study, from 12 units of atractor squid aggregate device that surveyed were found as many as 3,449 egg capsules attached with the number of capsules as many as 3-6 eggs of squid. Spesies of fish that are always found in the location of the drowned of atractor squid aggregate device is Lutjanus lutjanus.

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.
