Experimental Research of Piezoelectricity as Renewable Energy Power Source for Conveyor Electric Motor on Garbage Collection Vessel

There has been a lot of research on garbage collection vessels, but not many have utilized renewable energy. This research aims to utilize piezoelectricity as a power source for the conveyor of the garbage collection ship. When it rains, piezoelectricity will convert rainwater vibrations into electricity. This research uses an inner flat catamaran garbage collection vessel with a conveyor and a wing conveyor. The power source from piezoelectricity is planned to fulfil the power of the electric motor driving the conveyor. Piezoelectric experiments have been conducted with artificial raindrops with raindrop diameter variations of 8.5 mm, 10 mm, and 12 mm. The results have showed that the piezoelectricity required to support the electrical power of the conveyor is 520 pieces, with the average power generated is 55.69 watts per beat. In addition, the research has also produced a conceptual design of a garbage collection vessel with piezoelectricity on the ship's deck.
