<![CDATA[The digitalization of inventory management has become a strategic necessity for improving the efficiency and transparency of workshop operations in vocational education. However, its effectiveness is strongly influenced by the quality of workshop leadership and management practices. This study aims to analyze the influence of workshop leadership management on the effectiveness of inventory digitalization in the Computer and Network Engineering (TKJ) department at SMKN 1 Batam. A quantitative approach with an ex post facto design was employed. The research instrument consisted of a five-point Likert-scale questionnaire comprising 20 items measuring workshop leadership management and 15 items assessing digital inventory effectiveness. Content validation was conducted by experts in educational management and digital facility systems. Validity testing indicated that all items met the required criteria (r-calculated > r-table), while reliability testing resulted in Cronbach’s Alpha values of 0.873 for variable X and 0.895 for variable Y. Simple linear regression analysis produced the equation Y = 1.278 + 0.237X with a significance value of 0.000 < 0.05, and a coefficient of determination (R²) of 0.94, indicating that 94% of the effectiveness of digital inventory systems is influenced by workshop leadership management. The findings confirm that effective leadership practices—particularly planning, organizing, and supervision—play a dominant role in the successful implementation of inventory digitalization. This study contributes empirical evidence reinforcing the importance of workshop leadership in digital transformation within vocational schools and provides a foundation for developing a more comprehensive model of digital workshop management]]>
