Potential Development of the Future Vessel Fish

Potential Development of the Future Vessel Fish

1. Framework for the development of future
Litbangyasa results will be given to owners of fishing vessels at the site of research work, it is hoped that the technology will be obtained can be utilized by fishermen and transmitted to other fishermen to support the development of maritime industry and become a valuable technology information masyarakat.Meyakinkan with evidence of research results to the fishermen or owners bahwasannya drive fishing boat with inboard system more efficient when compared with outboard fishing boat system is the best way to transfer the technology to the fishermen who tend to tradition. Application inboard system has not been fully accepted by the owner of a fishing boat that uses a ring nets because the nets lodged constraints bali boat propeller. Besides the constraints on fishing vessels that operate through the muddy feared the propeller being damaged by mud. Therefore, it is necessary to do a more in-depth follow-up study in order to avoid both ersebut above.
The constraints use inboard engines for fishing boats with nets circumference (ring), and fishing boats operating in shallow muddy and rocky areas will find a way out and technology solutions best results.
 2. Development Strategy forward:
Traditional Fish Ship size 10-20 GRT using ring nets (Purse Seine) in the southern coastal waters of Madura Island and most of the northern coast using Outboard drive system. The use of the system allows the outboard propeller lifted to the surface by way of a vertical rotating propeller shaft with rotary axes on the machine foundation. Consideration of the use of the system to avoid damage to the outboard is stuck in the propeller nets because, in addition to avoiding damage to the propeller because aground dilumpur happened to fishing boats that operate through the river.
From the side thrust boats, outboard systems very unfavorable when compared to the inboard system. Outboard thrust system works on 30-45 º angle to the direction of movement of the ship so that it can be said with the system outboard thrust the ship would lose between 30-40%. While the system inboard engines with thrust that occurs in line with the movement of the ship in order to reach the optimum thrust.
Ring nets (purse seine) wrapped in a bunch of fish, after it's done hauling or withdrawal of dance drawstring bottom mesh netting to form a pocket. The next stage is the removal of fish with nets containing driving machine "axle" of the ship transverse direction. This condition is a critical stage which allows web position and shift the body under the bottom of the ship, so that the net can be lodged with the propeller on a boat inboard system.
Future Development Strategy to conduct a study and provide the best alternative design solutions in the use of ring nets on fishing boat inboard system to avoid jams on the propeller ring nets. Alternative in question include the planning system that allows inboard propeller axis can be lifted upward along the surface of the water as possible on a system where the outboard. Besides installing the application tunnel propeller on propeller as protective nets for jams. Both alternatives would be memerlukn studies and in-depth research to get the best propulsion system. The success of this design will have an impact on the achievement of the optimum vessel speed, fuel requirements decrease for the same mileage, vessel operating costs can be reduced, and quality assured as quickly catches up to the shelter.
