Introduction
Researchers observation in the field, mastery of basic skills of smash on volleyball games is still low and the lack of motivation of students in the learning practice of volleyball smash skills, such as students are not given learning skills models Smash, learning always monotonous and not much variation done during the learning of volleyball smash skills, as well as the lack of understanding students to the importance of mastering effective and efficient smash skills [1], this Because the technique of volleyball smash is considered a fairly complicated technique to be taught even more physical education teachers who do not have the background of volleyball sports in particular there are some schools that the physical education teachers is not derived from the scope of sports education [2].
The situation is influenced by several factors in the manner of educators, who have not yet maximised the learning process, using less precise models or methods of learning and not in accordance with the characteristics of the learning materials and Learners [3]. While the factors of the students among others, the lack of motivational learners in learning and feel difficulties with the material delivered. While the means and infrastructure factor is the lack of learning media such as volleyball, where the volleyball does not match the ratio between the number of learners with volleyball available. This is what causes learners to be less active and more pending a turn to perform the smash skills learned [4].
Therefore, physical education teachers need learning models with the right approach to improve the basic techniques of volleyball smash skills [5]. One of the solutions models of smash exercises that appeals to learners is to use rubber band tools. With these tools learners will gain new experience and can increase the motivation of learners to follow a ball smash exercise.
