THE DUAL ROLE OF SUPERVISOR SUPPORT AS PREDICTOR AND MODERATOR IN THE RELATIONSHIP BETWEEN IN HOUSE TRAINING AND EMPLOYEE PERFORMANCE

This study aims to examine the dual role of supervisor support, both as a direct predictor and a moderating variable, in the relationship between in-house training (IHT) and employee performance. The research was conducted at the Regional Office of the Directorate General of Treasury in Central Java, which regularly implements internal training programs as part of its human resource development strategy. Using a quantitative approach and a structured questionnaire, data were collected from 58 respondents selected using the Slovin formula from a total population of 68 employees. Data analysis employed multiple linear regression and Moderated Regression Analysis (MRA) using SPSS software. The research results are expected to demonstrate that in-house training can enhance employee performance, while strong supervisor support will strengthen this effect. Additionally, this study identifies supervisor support as an important moderating factor that reinforces the relationship between in-house training and employee performance. These findings emphasize the importance of creating a supportive supervisory environment to maximize the benefits of training programs, ultimately leading to improved organizational performance.
