The Influence of Work Discipline and Teacher Professionalism on Teacher Performance at SMK Negeri 1 Teluk Mengkudu

Abstract

This study was motivated by the suboptimal performance of teachers at SMK Negeri 1 Teluk Mengkudu, influenced by work discipline and professionalism. The research aims to analyze the effect of work discipline and teacher professionalism, both partially and simultaneously, on teacher performance. A quantitative approach was applied using census sampling, involving the entire population of 34 teachers. Data were collected through Likert-scale questionnaires, tested for validity and reliability, and analyzed using multiple linear regression. The findings reveal: (1) Work discipline has a positive and significant effect on teacher performance (t = 2.498; Sig. = 0.018 < 0.05). (2) Teacher professionalism also has a positive and significant effect (t = 3.326; Sig. = 0.002 < 0.05), with a more dominant influence compared to discipline. (3) Simultaneously, discipline and professionalism significantly affect teacher performance (F = 13.049; Sig. = 0.000 < 0.05). (4) The R² value = 0.457 indicates that 45.7% of performance variation is explained by both variables, while 54.3% is influenced by other factors. The study suggests strengthening discipline culture, enhancing professional competence through training and industry collaboration, conducting regular evaluations of teaching methods, and addressing external factors such as motivation, welfare, and supportive work environment.
