Judul: Status stok sumberdaya ikan kembung lelaki (Rastrelliger kanagurta, Cuvier 1817) di Perairan Selat Sunda
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.

Judul: Stock Status of Mackerel (Rastrelliger faughni Matsui, 1967) in the Sunda Strait
Abstrak: Ikan kembung (Rastrelliger faughni Matsui, 1967) merupakan salah satu jenis ikan pelagis yang memiliki nilai ekonomis penting, sehingga termasuk salah satu target penangkapan nelayan di Perairan Selat Sunda, Banten. Tujuan dari penelitian ini adalah menentukan status stok sumberdaya ikan kembung di Perairan Selat Sunda berdasarkan ikan yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Labuan Banten. Penelitian ini dilakukan pada periode Juni hingga Oktober 2014. Analisis yang dilakukan meliputi analisis nisbah kelamin, hubungan panjang dan bobot, tingkat kematangan gonad, fekunditas, sebaran kelompok umur, mortalitas, laju eksploitasi, dan model produksi surplus. Hasil yang diperoleh menunjukkan bahwa pola pertumbuhan ikan kembung betina maupun jantan adalah allometrik positif. Laju eksploitasi ikan kembung betina dan jantan telah mengalami tangkap lebih. Hasil tangkapan maksimum lestari dan upaya optimum sebesar 422 ton per tahun dan 758 trip per tahun.

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.
