Nowadays, technology and information are developing rapidly. It compels an organization or a company strive to excel in its field. In the Industrial Revolution 4.0 era, companies must maintain their assets and technology to face the competition. One asset that should be paid attention to is human resources. Human resource has two important variables, namely Organizational Citizenship Behavior (OCB) and Employee Engagement (EE). This study aims to analyze the relationship between OCB and EE on Employee Performance (EP) in the manufacturing industry in Tangerang. This study is conducted using a quantitative method with 200 respondents. The data is collected by distributing questionnaires to respondents, which is then analyzed using Structural Equation Modeling (SEM) with AMOS 23 software. The result of this study indicates that OCB has a significant effect on EE and EP. This study also finds that employee engagement has a significant effect on employee performance and can mediate the relationship between OCB and EP. From these results, the implication that can be taken is that the manufacturing industry in Tangerang must pay attention to their employees for them to develop OCB and EE, and eventually increase their performance towards the organization.
