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

Abstrak: Indian Mackerel (Rastrelliger kanagurta) is one of small pelagic fish that has a economic value. The purpose of this research was to determine the status of stocks and suggest management of Indian Mackerel (Rastrelliger kanagurta) and sustainability in the Sunda Strait based on catch data by fisherman landed on PPP Labuan, Banten. The research was conducted from May 2014 till October 2014. Total fishes that were caught is 480 individuals. The growth pattern of female Indian Mackerel is isometric and negative allometric for male Indian Mackerel. The amount of Maximum Sustainable Yield (MSY) and optimum efforts, 571 tonnes per year and the 1 010 trip per year. Exploitation rate was exceeded the optimum level is 0.5, implied that the Indian Mackerel fishery of Sunda Strait has been overfished. Management process that can be conducted is to regulate the fishing effort, fishing season, and mesh size.

Abstrak: Flavonoid is the most abundant naturaly-occuring polyphenolic compound which has C6-C3-C6 carbon skeleton. Flavone is a group of flavonoid with wide bioactivity spectrum. It is widely distributed in higher plants. Its bioactivities include antioxidant, HIV-1 proteinase inhibitor, strong and selective apoptotic inducer in human colon cell, and ligand for BDZ-R receptor. One of the important and widely applicable flavones synthesis route is through 1-(2-hydroxyphenyl)-3- phenylpropane-1,3-dione (1,3-diketone) acid-catalyzed oxidative cyclization. In this study, 1,3-diketone has been successfully synthesized via four-step route. In the first step, phenol was acetylated with 74–95% yields. Subsequently, phenyl acetate was converted to o-hydroxyacetophenone (o-HAP) with 34% yield via AlCl3-catalyzed Fries rearrangement. Benzoylation of o-HAP followed by Baker- Venkataraman rearrangement of the ester product using KOH in pyridine finally produced 1,3-diketone. The third and fourth steps yield were 27–44% and 82– 85%, respectively. All products in this study have been characterized spectroscopically. Melting point characterization were also conducted to the solid products.
