This study aims to analyze the effects of transformational leadership, organizational culture, and conflict of interest on the work motivation of public elementary school teachers in Dramaga District, Bogor Regency, both partially and simultaneously. A quantitative approach with a survey method was employed. The population consisted of 173 teachers, and a sample of 121 teachers was selected using the Slovin formula and proportionate random sampling technique. Data were collected through questionnaires and analyzed using IBM SPSS Statistics. The analytical techniques included descriptive statistics, multiple linear regression, t-test, F-test, and coefficient of determination (R²). The findings reveal that transformational leadership has a positive and significant effect on teachers' work motivation (β = 0.262; t = 7.037; p < 0.05). Organizational culture also has a positive and significant effect (β = 0.399; t = 7.508; p < 0.05), while conflict of interest has a negative and significant effect on teachers' work motivation (β = -0.170; t = -3.810; p < 0.05). Simultaneously, the three independent variables significantly influence teachers' work motivation (F = 74.182; p < 0.05). The coefficient of determination (R² = 0.656) indicates that 65.6% of the variance in teachers' work motivation is explained by the three variables, while the remaining 34.4% is influenced by other factors outside the research model. Organizational culture was found to be the most dominant factor affecting teachers' work motivation. Therefore, strengthening organizational culture, implementing effective transformational leadership, and minimizing conflicts of interest are essential to improving teachers' work motivation.
