River’s wave energy plant (PLTGS) is nonconventional energy plant that use vertical wave of river to produce eletrical energy. PLTGS in this research use direct current as magnetic force’s source in rotor. River’s Vertical wave will move rotor up and down towards the stator with coil variation 1500, 1750, 2000, 2250, and 2500 turns . The purpose of this research is to see how magnetic flu…
