Abstract

This study aims to analyze the influence of Teacher Discipline and Transformational Leadership on Teacher Job Satisfaction and Teacher Professionalism in schools. Using a quantitative approach with path analysis, the results of the study indicate that Teacher Discipline has a significant influence on Teacher Job Satisfaction and Teacher Professionalism, both directly and through job satisfaction channels. In addition, Transformational Leadership also has a significant influence on both variables, although slightly lower than teacher discipline. Teacher Job Satisfaction acts as a mediator between teacher discipline and transformational leadership with teacher professionalism. This finding confirms the importance of the role of discipline and transformational leadership in improving teacher professionalism through increasing job satisfaction. This study suggests that schools focus more on developing supportive discipline and leadership and creating a work environment that improves teacher satisfaction and professionalism.

Abstract

Background: The Indonesian Carbon Exchange (IDX Carbon) has emerged as a critical mechanism for carbon trading, introducing carbon units as securities rather than commodities. Despite this development, challenges remain in ensuring the integrity of carbon markets, including issues of double counting, manipulation of carbon unit measurements, and regulatory gaps. Objective: This study aims to examine the implementation of Carbon Emission Disclosure on Market Reaction with Green Investment as a mediating variable in companies listed on IDX Carbon. Methods: This study employed a quantitative research approach using SmartPLS with PLS-SEM. Hypothesis testing applied a t-statistic threshold of 1.96 and a significance level of α = 5% (p-value < 0.05). Results: All variables had Cronbach's Alpha values above 0.95 and AVE values above 0.66, indicating high reliability and validity. The R² value of Green Investment (Z) was 0.983 and Market Reaction (Y) was 0.925, indicating strong predictive relevance. Hypothesis testing revealed: (1) Green Investment significantly affects Market Reaction (t = 9.422, p = 0.000); (2) Carbon Emission Disclosure significantly affects Green Investment (t = 6.017, p = 0.000); (3) Carbon Emission Disclosure significantly affects Market Reaction (t = 2.655, p = 0.000); and (4) Carbon Emission Disclosure significantly affects Market Reaction through Green Investment as a mediating variable (t = 8.672, p = 0.000). All four hypotheses were accepted. Conclusion: Carbon Emission Disclosure has a significant direct effect on both Green Investment and Market Reaction in IDX Carbon-listed companies. Green Investment also serves as a significant mediating variable between Carbon Emission Disclosure and Market Reaction, highlighting the importance of transparent carbon emission reporting in supporting sustainable finance in Indonesia.
