Pengembangan Armada Pancing Tuna Dengan Rumpon Di Perairan Puger, Jawa Timur (the Development of Troll Lines Using Fish Agregation Device (Fads) in Puger Waters, East Java)

Fisheries sector is undergoing a crisis in global dimensions for the last few years caused of unsustainable consumption, overfishing, as well as the increasing of pollution and climate change distribution. One of the overfishing area is South coast Java Seas) where this has the potential resources of tuna included Puger waters. Tunas are catched by troll lines around fish aggregating devices (FADs). Increasing population of FADs can effect tuna resources such as: the size and qualities decreased. The results showed that the length of catched tunas were between 40-49 cm, the weights were from 0 to 3.5 kg, and the organoleptics were dominated on 6 scale. These indicated that tunas had the unexpected sizes and exportless. The rising of FADs utilization also contributed to the increasing insidence of conflicts among fishery stakeholders. There were three kinds of conlicts in Puger, such as: latent conflict (shipping crew and TPI), felt conflict (internal shipping crew), and manifest conflict (shipping crew-institution). Development strategy formula was conducted by SWOT analysis. The important thing for government to overcome these problems were continuing in area socializing, utilization programme of coastal area for integrated and sustainable fisheries

The Advantage of Slurry Ice as Cooling Media for Fish in Tropical Area

The result showed that slurry ice can decrease the temperature of carp (Cyprinus carpio linnaeus) to 00C in 14 minutes while conventional ice block only managed to drop the temperature to 2,50C with a P value of 0.029 > 0.05 (? = 5%).While on Mackerel (Rastrelliger neglectus), slurry ice could drop its temperature to 00C in 12 minutes whilst conventional ice blocks only managed to drop the temperature by 2,80C, P value of 0.0003< 0.05 (=5%). This paper illustrates that the use of slurry icecooling medium is very advantageous for cooling fresh fish that the fish will have higher price and quality. Slurry ice is a brine solution, which has a diameter of ice less than or equal to 1 mm, that can be pumped to refrigerate fresh fish products. This media is still not familiar in Indonesia because the technology has not been widely used by fishermen in the tropics. Local fishermen still use conventional cooling media in the form of ice blocks that are carried out by fishermen or fish farmers to cool the product. Tropical regions have different characteristics to subtropical, namely; the region have different seasons, thus affecting temperature and salinity of waters. This study aimed to prove the advantages of slurry ice cooling medium to drop the temperature of fish in the tropics. The method used was comparative analysis between slurry ice cooling media and ice blocks in the treatment of freshwater fish and seawater fish

Optimised combinatorial control strategy for active anti-roll bar system for ground vehicle

The objective of this paper is to optimise the proposed control strategy for an active anti-roll bar system using non-dominated sorting genetic algorithm (NSGA-II) tuning method. By using an active anti-roll control strategy, the controller can adapt to current road conditions and manoeuvres unlike a passive anti-roll bar. The optimisation solution offers a rather noticeable improvement results compared to the manually-tuned method. From the application point of view, both tuning process can be used. However, using optimisation method gives a multiple choice of solutions and provides the optimal parameters compared to manual tuning method
