Abstract: Human resources have a major role in every organizational activity. The resources of the organization will not provide optimal results if it is not supported by human resources who have a capable performance. To achieve good performance, performance variable cannot stand alone. This means that there are several supporting variables that can affect performance variable. Work motivation, Job Satisfaction, and Organizational Commitment are three variables that have an influence on improving employee performance. This is evidenced by previous researches that have been conducted. However, most of these researches took locus in private organizations or institutions. In this research, we took the place of research in state institutions. The purpose of this research were: First, to find out how work motivation influenced organizational commitment; Second, to find out how job satisfaction influenced organizational commitment; Third, to find out how work motivation influenced performance; Fourth, to find out how job satisfaction influenced performance: and Fifth, to find out how organizational commitment influenced performance. This research was conducted on respondents where all of them were Civil Servants of the General Secretariat of People's Consultative Assembly (MPR) of the Republic of Indonesia by using questionnaire media. Data analysis in this research used the Structural Equation Modeling (SEM) method. The results of this research suggested that high work motivation had a significant effect on organizational commitment, high job satisfaction would form high organizational commitment, but high work motivation did not affect performance, while high job satisfaction affected partially on performance, and apparently high organizational commitment did not directly affect performance. This research found evidence that organizational commitment was not mediation between work motivation and performance and job satisfaction with performance.
