Abstract

Employee performance is a critical determinant of organizational competitiveness and sustainability, particularly in labor-intensive industries such as palm oil processing. Although previous studies have confirmed the importance of leadership style and work motivation in influencing employee performance, empirical findings remain inconsistent across organizational settings, indicating the need for further investigation in specific industrial contexts. Limited studies have also simultaneously examined the relative contribution of leadership style and work motivation in the Indonesian palm oil processing sector. This study aims to analyze the influence of leadership style and work motivation on employee performance at PT Sawitmas Nugraha Perdana Sampit. Using a quantitative approach with a cross-sectional design, data were collected from 38 employees through a saturated sampling technique and analyzed using multiple linear regression. The results reveal that leadership style has a positive and significant effect on employee performance (β = 0.141; t = 2.358; p = 0.024), while work motivation exerts a stronger positive effect (β = 0.764; t = 8.698; p < 0.001). Simultaneously, both variables significantly influence employee performance (F = 68.367; p < 0.001) and explain 79.6% of performance variation (R² = 0.796). The novelty of this study lies in providing empirical evidence from the palm oil processing industry, demonstrating that work motivation contributes more substantially to employee performance than leadership style. These findings enrich human resource management literature and offer practical implications for managers in designing leadership development and employee motivation strategies to improve organizational productivity.

Abstract

This study was conducted in Sampit City to examine the influence of Country of Origin and Brand Image on Vivo smartphone purchase decisions, with Word of Mouth (WOM) as a mediating variable. The research involved 65 Vivo smartphone users selected through accidental sampling. Data were collected using questionnaires and analyzed using Structural Equation Modeling (SEM) based on Partial Least Squares (PLS) with WarpPLS 4.0. The analysis included validity and reliability testing, evaluation of the outer and inner models, and hypothesis testing. The results showed that the R² value for WOM was 0.415, indicating that Country of Origin and Brand Image explained 41.5% of the variation in WOM. The R² value for Purchase Decision was 0.430, indicating that the model explained 43.0% of the variance in purchase decisions. Country of Origin had no significant direct effect on Purchase Decision (t = 1.209; p = 0.227), whereas Brand Image and WOM did. WOM significantly mediated the relationship between Country of Origin and Purchase Decision (t = 2.367; p = 0.018), but did not mediate the relationship between Brand Image and Purchase Decision. The novelty of this study lies in integrating Country of Origin, Brand Image, and WOM within a single model to explain smartphone consumer behavior in a regional market context. The findings demonstrate that WOM strengthens the influence of product-origin perceptions on purchase decisions, while Brand Image remains a key determinant of consumer purchasing behavior.
