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: Growth of Lanjaman Shark (Carcharhinus falciformis) Landed in PPI Tanjung Luar, East Lombok
Abstrak: Carcharhinus falciformis merupakan salah satu jenis ikan hiu yang tertangkap dengan intensitas tinggi di wilayah Tanjung Luar, Lombok Timur. Penelitian ini bertujuan menganalisis pertumbuhan ikan hiu lanjaman yang dominan tertangkap dan didaratkan di Tanjung Luar, Lombok Timur, serta memberikan saran rekomendasi dalam pengelolaan konservasi. Data penelitian merupakan data hasil tangkapan selama periode waktu Juli 2016 sampai dengan Agustus 2018, dengan data yang digunakan dalam penelitian ini adalah data panjang, bobot, dan jenis kelamin. Jumlah total ikan contoh sebanyak 6931 ekor dengan jantan dan betina masing-masing 2866 dan 4065 ekor. Hasil nilai uji t melalui analisis hubungan panjang bobot menunjukkan bahwa hiu lanjaman jantan dan betina di tahun 2016 memiliki pola pertumbuhan alometrik negatif, sedangkan hiu jantan dan betina di tahun 2018 memiliki pola pertumbuhan alometrik positif. Nisbah kelamin jantan lebih sedikit dibanding jumlah betina dengan perbandingan 1:1,42. Parameter pertumbuhan menunjukkan bahwa koefisien pertumbuhan (K) hiu jantan di tahun 2016 dan 2017 lebih tinggi dibandingkan ikan betina, sedangkan nilai K jantan di tahun 2018 lebih rendah dibanding betina., Carcharhinus falciformis is one type of shark that is caught with high intensity in the Tanjung Luar area, East Lombok. This study aims to analyze the growth of lanjaman shark which caught and landed at the study site. The research data is catch data during the period July 2016 to August 2018, with the data that used in this study is length, weight, and sex. The total number of sample fish was 6931 individuals with 2866 and 4065 on males and females respectively. The results of the t-test value through analysis of the relationship between length and weight show that male and female lanjaman sharks in 2016 had a negative allometric growth pattern, while male and female sharks in 2018 had a positive allometric growth pattern. Sex ratio of male sharks (C. falciformis) was less than the number of females with a ratio of 1:1.42. The growth parameters show that the growth coefficient (K) of male sharks in 2016 and 2017 is higher than the female sharks, while the K value of males in 2018 is lower than the females.

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.
