A company is one of the organizations which is oriented for a business purpose, needs reliable and competitive human resources to achieve its goal. A successful Organization can be reflected in employee performance. Several factors that influence employee performance include; Organizational Culture in the company, Leadership Style of a leader in the company, and organizational commitment. This research aims to measure the influence of Organizational Culture and Leadership Style on Employee Performance through Organizational Commitment. A sample is taken from 98 employees using the census method. Path Analysis Model (SPSS version 23) is used as the analysis technique. The result shows that Organizational Culture does not have a significant effect on employee performance. Leadership Style has a significant effect on employee performance. Organizational Commitment is a variable that has not been able to mediate Organizational Culture and Leadership Style to improve employee performance since the direct influence of Leadership Style is shown greater than the indirect influence of Organizational Commitment. The Leadership Style is a very important variable in the Operational Department of PT Indolakto Pandaan. This will be used as a reference for the management of PT Indolakto in making policies to improve employee performance to achieve the set targets.
