The background of this research is the petanque precision shooting athletes who are inconsistent in obtaining scores. Accuracy is an important part of petanque, especially in the precision shooting numbers, so that it is necessary to have a mental training process that can contribute to the athlete's ability to improve their accuracy. The purpose of this research is to see the effect of a mental training in the form of self-talk on improving shooting accuracy in petanque. Looking at the objectives of this study, the pre-experimental method with the one group pre-test and post-test design has been used. The instrumental test in this study is a shooting test of 20 athletes from FIPJP (Fé dé ration Internationale de Pé tanque et Jeu Provenç al). The results of this research indicate that the test results are t = 2.690, with db = 19 and the number Sig. (2-tailed) or p-value = 0.014 <0.05. From this result, it can be concluded that self-talk practice can significantly improve the accuracy of the shooting petanque. The implication of self-talk is self-control. Athletes appear to be better able to control arm movements, control emotions, and regulate breathing when shooting. This can be seen from the increase in the scores of the athletes.
