Work Discipline and Employee Performance in an Islamic Hospital: Evidence from Bukittinggi, Indonesia

Abstract

This study analyzes the effect of work discipline on employee performance at Ibnu Sina Islamic Hospital Bukittinggi, Indonesia, where attendance records showed persistent lateness and absenteeism. Existing hospital studies report inconsistent findings and usually combine discipline with motivation or leadership, so its stand-alone contribution remains unclear; this study isolates discipline as the only predictor in a faith-based Class C hospital in West Sumatra. A quantitative correlational design was used. A total of 211 of 446 employees, selected through Slovin’s formula and simple random sampling, completed a validated five-point Likert questionnaire (Cronbach’s α = .945 for discipline and .967 for performance). Data were analyzed using descriptive statistics, classical assumption tests, simple linear regression, a t-test and the coefficient of determination. Work discipline had a positive and significant effect on employee performance (B = 1.449; β = .853; t = 23.660; p < .001) and explained 72.7% of its variance. The study contributes single-predictor evidence that discipline is a dominant, manageable lever of hospital performance, and it identifies recognition systems, consistent supervision and regular appraisal as practical priorities
