This study investigates whether personality and grit affect the Organizational Citizenship Behavior and if so, whether the effect is mediated by job involvement or not. Using a sample of 132 lecturers of Higher Education of The Ministry of Industry in Indonesia in 2018, this research revealed that personality and grit are positively related to the organizational citizenship behavior. This study proves that there is relationship between personality and grit with organizational citizenship behavior, and this relationship is partially mediated by job involvement. These empirical findings reinforce previous researches about the relationship between personality and organizational citizenship behavior. As the extension of the theoretical concepts constructed in this study, it also proved that the relationship between grit and organizational citizenship behavior is also partially mediated by job involvement. Finally, this finding offers the empirical evidence about the importance of job involvement on the relationship between personality and grit to organizational citizenship behavior. It indicates that the presence of personality and grit do not automatically increase the level of organizational citizenship behavior of lecturers, if there is no job involvement inside. This research recommends the strategy to increase the level of organizational citizenship behavior by optimizing the job involvement of lecturers.

This research and development (R&D) use the ADDIE development model. The development carried out in this study is limited to the 7th step, including problem identification, data collection, product design, design validation, design revision, product testing, and product revision. The subjects of this study were determined by using random sampling. Data collection was carried out by non-test techniques using interview guide sheets, validation questionnaires from media and material experts, and student response questionnaires. The results showed that the feasibility test of the product developed based on the material was in the excellent category of 91%. Furthermore, the results showed that the feasibility test of the product developed based on the assessment of media experts was feasible with 87.5%. User-based due diligence through limited trial also showed decent results with 97.7%. These results indicate that the multimedia-based learning media developed using Adobe Flash Professional CS6 is feasible for mass production after the final revision.
