PERANCANGAN ARCHIMEDES WINDMILL UNTUK PENGGUNAAN LAMPU SOROT KAPAL

To provide energy on fishing boat with the capacity under 30 GT especially for spotlights operational, fishermen still use diesel-fuel. Wind energy in the sea has not been optimally utilized, it can encourages efforts to utilize wind energy as an alternative energy. Archimedes Windmill is a new horizontal wind turbine type innovation that adopts the shape of a spiral of wind. With this unique design is very possible to be applied to fishing boats. First step for design of Archimedes Windmill is taking data for wind velocity in the sea of Java. Once the wind speed has been rated enough for use as a power plant, the next step is to plan the dimensions of the turbine blade for to provide energy of boat spotlights. Once the desired dimensions of the blade have been identified, the other components can adjust to form an ideal archimedes windmill. The result of design, to provide 4 kW energy for spotlights, must use 5486,968 Watt energy from turbine, with the outer radius of blade should be given (R1 = 1.5 m) and the deepest radius of blade (R2 = 9.3 cm). This dimension, make suitability design of Archimedes Windmill's aesthetic and be able to provide energy for spotlights operational
