Abstract :
The energy problem is one of the important problems for all developing
and developed countries. The current energy source still has a dependency on
fossil energy sources which are energy sources that will run out or cannot be
renewed. To meet the world's electricity needs, various power plants have been
pursued such as hydroelectric power, nuclear power plants, kinetic power plants
and other alternative power plants. Swing kids (swing children) can unwittingly
produce kinetic energy, basically the energy can not be destroyed but the energy
can change shape into other energy, so the kinetic energy produced by swing kids
can be converted into mechanical energy in the form of tensile forces can rotate
the generator so as to produce electrical energy. Then the electrical energy can
be generated from sources that have not been previously realized. The results of
the study at a 180° pull angle obtained an average voltage of = 7.63 V and an
average current of = 0.18 A. At a 160° tensile angle obtained an average voltage
of = 7.72 V and an average current average of = 0.13 A. At an angle of 150° pull
obtained an average voltage of = 5.94 V and an average current of = 0.11 A. At
an angle of pull of 140° obtained an average voltage of = 6 , 97 V and an average
current of = 0.13 A. At a pull angle of 130° an average voltage of = 5.06 V is
obtained and an average current of = 0.06 A, the load used in the test is LED (as
an indicator).
