Judul: Aspek Pertumbuhan Ikan Cucut yang Didaratkan di Pelabuhan Karangsong, Kabupaten Indramayu, Jawa Barat
Abstrak: This study of shark growth held in Karangsong’s port, Indramayu, West Java. The research was began in June to August 2012. Morphometric measure taken from the all sharks which landed in that port during research. There was 3 order, 5 family and 10 species of shark’s recorded but only 2 dominant species had become the main study, it was Carcarhinus dussumieri and Chiloscyllium punctatum. Both of this species had length between 60-100 cm. Growth coefficient (K), asymptotic length (L∞), and age when fish length is theoriticaly 0 (t0) for C. dussumieri is 0.63, 97.44, and -0.18, and C. punctatum 0.32, 90.40, and -0.38. This differences caused by different of its reproduction type, which C. dussumieri gave birth of its pup and C. punctatum laying its egg in seafloor. Sex ratio of these two sharks is equal both male and female (1:1), so we can assumed that there is no sexual segregation both of this species. Recommendation for the management is with limiting output quantities such control the limit of sharkfin export.

Judul: Studi Pertumbuhan Kepiting Bakau (Scylla serrata Forskal, 1997) di Perairan Karangsong, Kabupaten Indramayu, Provinsi Jawa Barat.
Abstrak: Scylla serrata is one of dominant catches in Karangsong water using bubu. High continously catch on activity could reduce on number of the mud crab population. This study was conducted in Juni-September 2013. Crab sampling was conducted in Karangsong water each 1 month. Length frequency distribution of male mud crab ranged between 60-138 mm, while females between 74-139 mm. Crab’s growth patterns in water of Karangsong is negative allometric. Through the analysis of growth parameter estimation, can be obtained K = − ln (􀜾����), L∞ = 􀯔���� 􀬵����􀬿����􀯕����, and t0 for mud crab males and females are respectively, K equal to 0,39 and 0,42 per month, L∞ equal to 157.35 and 147.99 mm, with t0 - 0,26 and -0,24 months

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.
