Judul: Performance of Ship Dimensions and Engines Gillnet in Several Marine Areas in Indonesia
Abstrak: Pengadaan kapal gillnet untuk meningkatkan pemanfaatan sumberdaya perikanan membutuhkan acuan standar ukuran kapal gillnet. Apabila kapal perikanan beroperasi tidak sesuai dengan fungsinya, berpotensi menyebabkan tidak efektif dan efisiennya operasi penangkapan. Oleh sebab itu, dibutuhkan acuan untuk menanggulangi hal tersebut. Data diambil dari berbagai sumber untuk mengetahui keragaan kapal gillnet di Indonesia dan diolah menggunakan Google Collab Python untuk mendapatkan gambaran umum keragaan kapal gillnet. Kapal gillnet tersebar di beberapa wilayah Indonesia dengan total 610 unit kapal. Dengan jumlah tertinggi di WPP 718 terdapat 354 unit dan terendah di WPP 715 terdapat 5 unit. Sebagian besar kapal gillnet dibuat di Indramayu dan menggunakan kayu. Menggunakan daya mesin mulai dari 60 PK hingga 1500 PK. Pemilihan daya mesin pada kapal tidak selalu bergantung pada ukuran kapal saja namun mempertimbangkan faktor ekonomi nelayan. korelasi setiap variabel seperti hubungan antara LoA, lebar, dalam, daya mesin, dan kapasitas palka memiliki nilai korelasi positif yang artinya setiap variabel memiliki perbandingan yang lurus., Ship procurement gillnets to increase the utilization of fisheries resources requires a standard reference for ship size gillnets. If fishing vessels operate inconsistently with their function, it has the potential to cause fishing operations to be ineffective and inefficient. Therefore, a reference is needed to overcome this. Data is taken from various sources to determine ship performance gillnets in Indonesia and processed using Google Collab Python to get a general idea of the ship's performance gillnets. Boat gillnets spread across several regions in Indonesia with a total of 610 ships. With the highest number at WPP 718 there are 354 units and the lowest at WPP 715 there are 5 units. Most of the ships gillnets made in Indramayu and using wood. Uses engine power ranging from 60 PK to 1500 PK. The choice of engine power on a ship does not always depend on the size of the ship but takes into account the economic factors of fishermen. The correlation of each variable, such as the relationship between LoA, width, depth, engine power and hatch capacity, has a positive correlation value, which means that each variable has a straight comparison.

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.
