Repowering SHIP FISH FROM Outboard TO Inboard SHIP TO IMPROVE EFFICIENCY PKPP-64/2012

Repowering SHIP FISH FROM Outboard TO Inboard SHIP TO IMPROVE EFFICIENCY PKPP-64/2012 ABSTRACT Most of the fishing communities on the coast of Java and Madura uses wooden boats as a means of transportation to catch fish. The type and size of boat used vary in size small (canoe) and large size (30 GRT). Placement of the ship propulsion system is determined by many factors customs and traditions of the local community. Mover (main engine) engine fitted as many outborad (twin screw) with a foundation of a machine that can be moved vertically. Propulsion system with such a lot of weakness in terms of technology, including: fuel wasteful, excessive vibration, propeller efficiency ugly because it operates on an inclined plane that is large enough (> 30 degrees), opening the stomach caused by the driving system will lead to dead water, placing less steering right, the speed of the ship is not optimal, as the boat foundered could not maneuver. Besides the propeller as the boat-mounted propulsor average is not matching with the engine penggeraknya.Dengan electoral system changes mover (engine, propeller and rudder) the right will bring significant change in the performance of the boat. Thrust generated by the propulsion system which makes an angle (outboard) will be smaller when compared with the direct drive system with the movement of the boat (inboard system). As a result, with the same engine power to achieve a given speed takes more fuel or shorter cruising range. Besides, the vibration caused by the much larger outboard systems, which resulted in the exhaustion of construction and maintenance costs. Keywords: fishing boats, marine transportation, machine-drive, out-board, twin screw, inboard, single screw, speed, vibration, maneuverability, fuel, efficiency.
