The Effect of Competence, Work Discipline, and Work Environment on Crew Performance at PT Pelayaran Dharma Indah

Abstract

This study examines the effects of competence, work discipline, and work environment on crew performance at PT Pelayaran Dharma Indah. The study was motivated by a decline in internal crew-performance audit scores from 89% in June 2024 to 79% in December 2025, particularly in operational and safety aspects. An associative quantitative design was applied from April to May 2026. From a population of 92 crew members, 75 respondents were determined using the Slovin formula and selected through convenience sampling. Primary data were collected using a five-point Likert questionnaire and analyzed with Structural Equation Modeling-Partial Least Squares using SmartPLS 4.0. The results show that competence affects crew performance, whereas work discipline and work environment have no statistically significant effect. The model explains 79.7% of the variance in crew performance. The findings emphasize strengthening knowledge, skills, professional attitudes, and technical capability through training, operational and emergency-procedure briefings, and periodic competency evaluation
