Abstract

This study examines the impact of servant leadership on the performance of Catholic religious teachers, with competence and professional commitment as mediating variables. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), data were collected from 151 Catholic religious teachers in the Jakarta Archdiocese. The results show that servant leadership has a direct positive impact on teacher performance (β = 0.317, p 0.001) and indirectly enhances performance through competence (β = 0.199, p = 0.008) and professional commitment (β = 0.186, p = 0.002). Competence (β = 0.357, p = 0.001) and professional commitment (β = 0.340, p = 0.002) significantly improve teacher performance. The structural model explains 74.9% of the variance in teacher performance, indicating strong predictive power. This study contributes to the literature by demonstrating the mediating role of competence and professional commitment in the relationship between servant leadership and performance, particularly in Catholic education. The findings provide practical implications for school administrators and policymakers to implement servant leadership strategies that enhance teacher competence and commitment. This research introduces a comprehensive approach to improving teacher effectiveness in religious education settings, emphasizing the importance of leadership styles that prioritize service, empowerment, and professional development.

Abstract

Customer satisfaction is a key indicator of long-term success in the logistics industry. This study aims to empirically examine the simultaneous influence of service quality, price, and facilities on customer satisfaction among PT's customers. J&T Express, a major courier company operating amid Indonesia’s rapid e-commerce expansion. Data were collected from 200 active customers via a quantitative, cross-sectional survey. Service quality was measured using an adaptation of the five SERVQUAL dimensions. The data were analyzed using partial least squares structural equation modeling (PLS-SEM) with SmartPLS 4.0. Results indicate service quality is the strongest predictor of customer satisfaction (β = 0.46, p < 0.001), followed by price (β = 0.32, p = 0.004) and facilities (β = 0.21, p = 0.012). The structural model explains 62% of the variance in customer satisfaction (R² = 0.62). Further analysis revealed that responsiveness and tangibles were the most influential subdimensions of service quality. These findings suggest that PT. J&T Express should prioritize improving service responsiveness and physical service evidence while maintaining competitive pricing. This study provides empirical evidence on the relative importance of satisfaction determinants in the courier service industry and offers practical guidance for enhancing services.
