Judul: Analisis Bioekonomi Sumber Daya Ikan Kembung Lelaki (Rastrelliger kanagurta) yang Didaratkan di TPI Blanakan, Subang, Jawa Barat
Abstrak: Indian mackerel (Rastrelliger kanagurta) is one of the economically important fish landed in TPI Blanakan. The purpose of this research is to know surplus production model that best fits the characteristics of fisheries indian mackerel through the application of five models that Schaefer, Fox, Walter Hibron, Schnute, and Clarke Yoshimoto Pooley (CYP). Research was conducted from July to August 2013. Schaefer Model is the model most appropriate surplus production to basic management of fisheries for indian mackerel in TPI Blanakan, although the value of the coefficient of determination (R2) of only 36%. Based on the results of bioeconomic analysis that the actual condition of the ndian mackerel resource in Blanakan has experienced overfishing. Maximum catches sustainable and economically optimum level of effort is 49.808 kg/year and 493 trip/year. Management plan that can be done is to set up an attempt arrest and quota setting catches.

Judul: Kajian Stok Ikan Kembung Lelaki Rastrelliger kanagurta (Cuvier, 1816) di Perairan Selat Sunda yang Didaratkan di PPP Labuan, Banten
Abstrak: Indian Mackerel (Rastrelliger kanagurta) is one of the small pelagic fish that has a significant economic value. It is abundant and caught dominantly in Sunda Strait. This study was aimed at examining the stasus of the Indian Mackerel (Rastrelliger kanagurta) stock, landed in PPP Labuan. The research was conducted in June 2013 to October 2013. Total fish caught were 1100 individuals. Length and weight relationships resulted in negatively allometric growth pattern. Analysis of resource potential of the Indian Mackerel was completed using Schaefer model, which was resulted in fMSY of 6078 trip per year and MSY of 1872 tonnes per year. Exploitation rate reached optimum level between 0.61-0.87. It is implied that the Indian Mackerel fishery of Sunda Strait landed in PPP Labuan has been overfished

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.
