Furthermore, simultaneously the value of Fcount variable job satisfaction, compensation and work motivation is 5.798 Frabel value of 2.76 where Fcount > Frabet (5.798>2.76) sig value (0.001 <0.05). The value of adjusted Rsquar is 0.222 or adjusted R2 x 100% of 22.2%, meaning the independent variable of the study. contributed very little in explaining employee performance by 22.2% while the remaining 77.8% were other variables that were not explained in this study, or were influenced by other factors.
