Against Student Satisfaction and Loyalty Impact on Students at University of Mercu Buana Bekasi researcher the research sample was taken a total of 100 active student of Master of Management of the University Mercubuana Bekasi grouped by status semestemya to be sampled proportionally. In this study sample will be used using the formula Structural Equation Modeling (SEM), which is an evolution of structural development, namely and models simultaneous equations in econometrics, then combined with the principles of measurement and psychological (such as factor analysis), and analysis of trajectory and sosiologt and biology into a structural equation model. The analysis shows the validity of the testing performed by using the correlation formula moment.rhitung product obtained from the output, the value is then compared with the value rtabel (0.138) is obtained from a reference standard statistical books. Validity testing showed that all the indicators used to measure the variables used in this study had a correlation coefficient greater than , For samples sebanyak 40 people on a real level α = 5% {0.05}. The results were obtained structural equation Y = 0,74X1 + 0,10X2 + 0,28X3 + 0,56X4 and Z = 1,07Y + 0,17X1 + 0,31X2 + 0,029X3 + 0,15X4. The structural equation it can be seen the value of R² (coefficient of determination) for each of the relationship equation.
