Abstrak: PPI Muara Angke is one of the fisheries landing sites which is located in DKI Jakarta. Fishing gear that is often used in PPI Muara Angke is purse seine. The aim of this study was to analyze the technical, biological, social and economic aspects of purse seine fishery in PPI Muara Angke. The method of this research was a survey method by analyze each aspects descriptively. Technically, purse seiner in PPI Muara Angke have size 25-125 GT and operate in the North region of the Java Sea, Bangka Belitung, Karimata Strait, Natuna Sea, South region of the China Sea and the others. The number of fisherman is 30-40 people. Biologically, the fishing gear has high catch species diversity with a low selectivity. Socially, purse seine fisheries in PPI Muara Angke implement sharing system, money deposits and wages catch bait. It is can also be well received by the local community. Economically, purse seine fisheries in PPI Muara Angke gain huge profits and having a good investment prospecting.

Judul: Kebijakan Pungutan Hasil Perikanan (PHP): Studi Kasus Perikanan Purse Seine Pelagis Kecil di Pelabuhan Perikanan Nusantara (PPN) Pekalongan
Abstrak: Purse seine fishery in North Java coastal represent one of effort capture fishery which becoming importance for fishery society in Central Java, especially Pekalongan city. The purpose of this research is to analyze effort of occupation, value of ship productivity and fish composition, fish price standard (HPI), and volume an reward (%) of PHP towards of ship purse seine small fish pelagic. This research was studied during January to June 2006 for primary collecting data at Pekalongan Fishing Port, Central Java. Method used in this research is literature study and survey method. The result show that all purse seiner are capable to operate except for 81 GT ( 2004 & 2005) and 65 GT (2005) vessels; However and the productivity of purse seiner was decreased until 14,5 % - 60,9 % for 2004 and 2005. The standard of fish price was appropriated by Ministry Regulation and Rewards of PHP have opportunity increasing equal to 3.5 % – 4.5 %.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol.
