Perencanaan Dan Fabrikasi Sistem Propulsi Mini Sumber Penggerak Baterai (ACCU) Sebagai Alat Bantu Renang Atau Snorekeling

The electric propulsion system in this system is a useful system to facilitate movement in water. Using an electric motor as a driving source supplied by a battery (ACCU). Which is packaged using a watertight box to protect the motor and drive source from water. The components used in this propulsionelectric system use watertight components, so that they can function optimally when used for snorekeling. Using 4 inch PVC pipe. Effective electrical power using a 12 VDC 6 Ampere Hours (AH) accu voltage source with 72 watts of power. The electric motor as a driving device uses a 12Volt DC motor with a maximum power of 400 Watts. The propeller shaft uses PA material with a diameter of 10 mm and is lightweight and does not rust when used. For the propeller using stainless alluminum material with a plate 2 mm thickness 3 leaves with a diameter of 5 inches. The basic working principle of this tool is to convert electrical energy from the battery into rotational energy in the motor, then the motor rotation is coupled with the propeller shaft used to rotate the propeller, which will ultimately produce thrust to the user.
