Abstract :
The taekwondo match is led by a referee and three judges in charge of giving
scores to athletes who get points. The position of these judges is at the edge of the
determined arena. The judging system requires many devices such as joy-stick, in-
focus and a computer that each device must be connected to each other by using a
wire, this method is felt to be less effective where the position of the cable should not
be touched or trampled by the player or referee in the match area. To overcome this,
it is necessary to design a judging system that utilizes Android with wireless networks
to make it easier to give points. The judging process as described can be improved by
utilizing information technology in the form of an Android smartphone for judging by
using an input device in the form of an Android phone that serves to enter points that
will later be displayed. The test results show that the aplicatin are more compatible
with the World Taekwondo Competition Rules & Interpretation 2018compared to the
previous tools that have not been used in the latest regulations.
