Abstract

This study analyzed the effect of work competence, workload, and adversity intelligence on employees’ performance with work motivation as an intervening variable. Besides, it aimed to improve employees’ understanding and performance at KSP KOPDIT Mitan Gita in Maumere, Sikka. Moreover, the study was associative-quantitative with a correlational approach and path analysis, to examine the relationship among the variables on employees’ performance through work motivation. The population was 138 permanent employees at KSP KOPDIT Mitan Gita. Furthermore, the data were collected through questionnaires and documentation. The testing included validity, reliability, F-test, determination coefficient (R2), and t-test. As a result, the descriptive statistics test identified the significant effect of deadlines, work patterns, flexibility, and life needs on employees’ performance. Additionally, the result of validity and reliability was guaranteed (Cronbach’s alpha 0,60). The independent regression model was free from normality, multicollinearity, and heteroscedasticity. In addition, the result of the path analysis showed that work motivation was effective as a mediator with the best model (R2 56,56%). In short, work competence, workload, and adversity intelligence had a significant effect on employees’ performance at KSP KOPDIT Mitan Gita, with work motivation as an important mediator.

Abstract

This study examines the impact of product quality, price, and promotion on iPhone purchasing decisions among STIESIA Surabaya Z-generation students, with brand image serving as a moderating variable. Furthermore, the study employs a quantitative approach, specifically a survey. The data was collected using purposive sampling. In accordance with this, 134 respondents were chosen because they matched the criteria for validity or reliability as samples. Moreover, the data analysis technique used was Structural Equation Modelling Partial Least Squares (SEM-PLS). The evaluation results in the measurement model indicate that all constructs met the criteria. Meanwhile, structural model evaluation indicates that the model describes effectively. Additionally the hypothesis test found that price has a positive and significant impact on purchasing decisions. However, both product quality and promotion have insignificant effects. In addition, brand image increases the influence of product quality while decreasing the effect of price. Unfortunately, it does not considerably moderate the effect of promotion. The findings lead to the conclusion that Z-generations' purchasing decisions for premium products are driven more by perception of value and brand image than functional qualities and promotion.
