This study aims to analyze the influence of human resource (HR) development, work motivation, and competency improvement on employee performance at PT Perkebunan Nusantara I Regional 7 Kebun Kedaton. The research method used is quantitative with a survey approach to a sample of 100 respondents selected based on work productivity criteria. Primary data collection was carried out through the distribution of Likert 1–5 scale questionnaires. Data were analyzed using the Structural Equation Modeling method based on Partial Least Square (SEM-PLS) through SmartPLS software. The results of the study showed that human resource development, motivation, and competency improvement had a positive and significant effect on employee performance, both partially and simultaneously. Work motivation was proven to be the most dominant variable in influencing performance achievement. Simultaneously, the three exogenous variables were able to explain the variation in employee performance by 54.7%, while the remaining 45.3% were influenced by other factors outside the research model. These findings indicate that the integration of capacity building programs through career clarity, the provision of motivational stimuli based on work pride, and the strengthening of field operational competencies are essential strategies in optimizing the productivity of plantation companies.
