Judul: Performa gerak crankbait berdasarkan sudut diving lip, kecepatan tarik dan panjang tali pancing tonda (Troll Line).
Abstrak: Troll line is one of the traditional fishing gear that used for catch pelagic fish with high economical value. Troll line operation by dragging in the water with constant speed, so fish will attracted to the lure and chase it. One of lure that common used in this methode of fish catching is crankbait type of Artificial bait. Artificial bait is more popular than the natural bait, because this kind of bait have more resistant and easy to control it than using the natural bait, and crankbait type is common used because of it characteristic that when this type of lure being dragging by boat, it will be dive to certai depth. This research is to indentify factors that influence the depth of this lure. The results shows that the angel of diving lip have a big influence to the depth of the lure,with the best angel of diving lip is 10º. Other factor that show big differences of lures depth is the amount of the line. The model of the lure with dragging speed and range and the line can be specified with D = - 0.984 + 0.0601 X1 + 0.852 X2. This result may be vary depend on kind of bluff body of the lure, and other conditions.

Judul: The Development of Troll Lines Using Fish Agregation Device (FADs) on Puger Waters, East Java.
Abstrak: Nowdays fisheries sector is undergoing a crisis in global dimensions for the last few years and it has led to the unsustainable consumption, overfishing, as well as the increasing of pollution and climate change distribution. One of the utilization of fisheries resources is tuna especially in South coast Java Seas included Puger seas. Tunas are catched by troll lines using FADs. the using of troll lines and FADs have been found on small scale fisheries. The increasing troll line fleet was caused by the rising number of FAD on Puger water and it has caused bad influence toward the fish stock and social environment which has led to a conflict between fishermen and stakeholders. They usually fought on existing fish stock and it stepped to another conflict. The fish quality from troll line fleet was not feasible due to bad fish handling on board. Another problem that occured on troll line fishery in the Atlantic Ocean was the increasing number of catch unit around the FAD and had caused the declining of tuna fish production and size which economically not favorable and cannot be exported because it must fit the minimum weight requirement of 25 kg. The objectives of this research is to evaluate the FAD equiped troll line fishery and formulating the troll line fishery management strategy on the water of Puger in East Java. This research could be beneficial for stakeholders about the FAD influence on troll line fishery in Puger and as information for academician and researcher about tuna quality that was landed on Puger fishing port and this research could be as recommendation for the local government and related fishery department in managing the troll line equiped with FAD. This research was conducted on January until May 2013 on Puger Fishing Port in Jember East Java when the lean season of Tuna occured at that time. The choice of this location was triggered by the leak of information about troll line fishery around the FAD area in the water of Puger. Two types of data were collected in this research. The secondary data was statistic data which collected from the Puger fish landing port, Veterinar Fishery and Marine Department of Jember Region, BPPPI Department (Balai Pengelola Pangkalan Pendaratan Ikan), Marine and Fisheries Department of East Java. The primary data was collected by interviewing the stakeholders, fishermen, boat owner, fish landing port department and wholesaler also. Result showed the average value of troll line production in the last five years increased by 1436,7 kg/unit. Because of the high fish exploitation on Puger Water the tuna fish size that were landed did not conform the export criteria where the ideal body length interval is 40-49 cm. The tuna organoleptic value in Puger were dominated by scale 6 which did not conform the standard quality also. This was caused by unappropriate post catch fish handling that was done onboard by the fishermen. The main focus was to manage the troll line fishery in Puger which was equipped with FAD. Things that need to be done to solve these problem is by

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.
