A total of 75 active student organization members participated as respondents, selected using a purposive sampling technique. Data were analyzed using the Partial Least Squares (PLS) approach with SmartPLS 3.0 software. The findings reveal that both organizational communication and culture significantly impact the level of commitment among student organization members.

These results highlight the crucial role of communication and culture in fostering strong organizational commitment, which contributes to the overall success of student organizations
