The results showed that the value of F arithmetic amounted to 18,597 when viewed from the significant value then obtained the value of sig 0.00 <a = 0.05 then Ho is rejected and Ha accepted. This means there is a relationship between variable discipline / independent (X) on productivity variables/dependent (Y). The results showed that there is a positive influence between discipline on employee productivity indicated by t arithmetic = 4.312 and t table = 0.433 then t arithmetic > t table Medium R Square value of 0.470 Means that the independent variable work discipline (X) is able to explain the dependent variable work productivity (Y) of 47% while the remaining 53% is influenced by other variables outside the study.
