Judul: Manajemen Operasi Unit Penangkapan Gillnet Millenium 30 Gt Di Ppi Karangsong, Kabupaten Indramayu
Abstrak: Tingginya jumlah unit penangkapan gillnet millenium 30 GT di PPI Karangsong mengakibatkan terjadinya persaingan antar pelaku usaha, sehingga diperlukan adanya manajemen operasi yang baik agar produktivitas dapat ditingkatkan. Tujuan dari penelitian ini yaitu menghitung produktivitas unit penangkapan gillnet millenium di PPI Karangsong, menentukan faktor yang mempengaruhi produktivitas unit penangkapan gillnet millenium di PPI Karangsong, dan mendeskripsikan manajemen operasi unit penangkapan gillnet millenium di PPI Karangsong. Perhitungan produktivitas menggunakan pendekatan rasio input/output. Berdasarkan perhitungan produktivitas, kapal 4 memiliki produktivitas tertinggi, sedangkan produktivitas terendah diperoleh kapal 2. Analisis fungsi produksi menggunakan persamaan Cobb-Douglas. Faktor-faktor produksi yang berpengaruh secara bersama-sama terhadap produktivitas yaitu jumlah trip, jumlah tenaga kerja, jumlah bahan bakar, panjang jaring dan lebar jaring. Faktor-faktor produksi yang berpengaruh secara sendiri-sendiri yaitu jumlah trip dan jumlah bahan bakar.

Judul: Optimasi Teknis Perikanan Gillnet Millenium di Desa Karangsong, Kabupaten Indramayu
Abstrak: Northern Java Sea has already know as one of the most productive sea in Indonesia. Development of PPI Karangsong, is one of Fisheries development policies of Indramayu Regency for increasing the regional economic growth. Gillnet millennium is one of the most popular fishing gear in PPI Karangsong. Fishermen in Karangsong use gillnet millennium in some variation type of technical and operation method. This study aims to determine which gillnet millennium variation type has the best optimization score. This study was held by using survey method, and the data collected by purposive sampling method. Based on the results of the study revealed that the ship that operate in the PPI Karangsong made of wood with the size of the 5 GT, 20 GT, 30 GT, 40 GT and 60 GT. .Gillnet millenium that are used by fishermen made of polyamide monofilament material, the size of the gillnet millenium that is operated on the basis of the size of the ship is all 20 pieces up to 110 pieces. The fishermen in karangsong most of the fishermen are full. The score of the function for four groups as studies object are 0,18 (< 10 GT), 2,812 (20 GT), 1,824 (30 GT), and 2,89 (> 40 GT). Production factors that influence the optimization of gillnet millennium are depth of the net, number of day of the trip, and the fishing location.

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.
