That the F test result is 87. 386 with a significant level of 0.000, while the Ftable value of 3.332. When compared to the value of fcount 87.386> ftable 3.332 at α 5%, the conclusion is that simultaneously the Knowledge, Work Discipline and Communication Ability variables have a positive and significant effect on Employee Performance, that the tcount value for the Knowledge variable is 0.321, Ability is -0.057, Work Discipline is equal to 3.605, and communication of 4.391 with a significant value of each independent variable (4.163), (0.000). Whereas for the t-table value in the t distribution statistical table with level of test α = 5% and Dk = n - k, 40 -5 = 35 with a sig value of 5%, the value of t table = 1.869. Based on the criteria that if the value of tcount> ttable H0 is rejected , on the other hand tcount <ttable, H0 is accepted.  : (0.321> 1.869), (-0.057 <1.869), (3.605> 1.869), (4.391> 1.869).
