This research was conducted at Bengkong Police Station, Barelang Police Station, with the target respondents being Personnel. In this study, the number of Personnel who were used as respondents was 41 respondents. The research tool used was a Questionnaire. While the analysis tool used was SPSS 19. The description of the research results is as follows. In testing the hypothesis whether the Work Communication variable has an effect on Personnel Performance, then Because t count (10.470)> t table (1.664), then Ho is rejected and H1 is accepted, meaning; The regression coefficient is significant or the Work Communication variable has an effect on Personnel Performance. In testing the hypothesis whether the Teamwork variable has an effect on Personnel Performance, then Because t count (14.483) > t table (1.664), then Ho is rejected and H1 is accepted, meaning; The regression coefficient is significant or the Teamwork variable has an effect on the Personnel Performance variable. In testing the hypothesis whether the Personnel Training variable has an effect on Personnel Performance, then Because t count (15.757) > t table (1.664), then Ho is rejected and H1 is accepted, meaning; The regression coefficient is significant or the Personnel Training variable has an effect on the Personnel Performance variable. In testing the hypothesis whether the Work Communication, Teamwork and Personnel Training variables simultaneously have an effect on Personnel Performance. The Anova test produces an F count of 39.798 > F table 2.49 with a significance level (probability number) of 0.05. F count > F table then Ho is rejected and H1 is accepted. So the regression coefficient of Work Communication (X1), Teamwork (X2) and Training (X3) together have a significant effect on the variable of Personnel Performance (Y).
