Innovation model of Volleyball Shooting Machine

Abstract

This research aims to create an innovative prototype of a volleyball launcher for improving ball-handling skills in volleyball. To build a low-cost volleyball launcher Easy to move, easy to use, and can be used more practically. They wanted to test the performance of the volleyball launcher prototype innovation. To be used as a tool to facilitate volleyball coaches. However, the researcher has studied volleyball and sports innovations, therefore, has foreseen that the prototype of the volleyball launcher will benefit those involved in basic volleyball training. And is a factor in training for athletes or initiators in volleyball. This innovative volleyball launcher prototype uses battery power through two motors to shoot the volleyball into the athlete. Can adjust the degree and elevation To control the direction of the volleyball as needed and if the athlete wants to receive in the same way repeatedly, good skill. Can set degrees or where you wish the volleyball to fall. Determination of the efficacy of the volleyball launcher prototype innovation through an expert opinion questionnaire to analyze its accuracy. And a general public opinion questionnaire to analyze sentiment. It was found that the experts agreed. The results of the experts' questionnaires had an overall IOC level of 0.90. The results of the content validity examination were at a reasonable level. The public's assessment of the overall volleyball launcher innovation is valuable. Alpha Cronbach is equal to 0.953. Indicates that the internal consistency or reliability of the questionnaire is high.
