This research is based on Table Marking Instruments that still use manual
systems in the process of training forehand and backhand accuracy, as well as the
absence of training aids with multifunctional systems that can be used in forehand
and backhand accuracy exercises in table tennis sports. Therefore, researchers
developed a modified ball box tool from table marking instrument as an exercise
tool to improve the accuracy of forehand and backhand in table tennis.
This research is a research development or Research and Development
(R&D). This research was conducted with several steps, namely: (1) Potential
problems, (2) Data collection, (3) Product design, (4) Design validation, (5)
Design revision, (6) Product trial, (7) Product revision, (8) Use trial. The
development of ball box tools for practice improves the accuracy of forehands and
backhands first validated by material experts, media experts, and 8 players for
small-scale trials and 16 players for large-scale trials. The subject of this study
was PTM Gris Semarang. Data collection techniques used in this study using
instruments in the form of questionnaires. Technical analysis of this research data
is the descriptive qualitative and descriptive quantitative percentage.
The results of this study show that the ball box tool is very feasible to be
used as a table tennis exercise aid. The result is obtained from the last validation
result a) material experts by 93% or very feasible; b) media experts by 95% or
very decent; c) field trial athletes of 90.31% or very decent. Thus, the conclusion
that the ball box tool for exercise improves the accuracy of the forehand and
backhand has been declared very feasible to be used for exercise aids in the sport
of table tennis.
