Abstract

The rapid growth of live commerce in Indonesia has significantly transformed consumers’ online shopping behavior, particularly through TikTok Live. This study aims to examine the effect of interactivity and visual appeal on impulse buying of fashion products in TikTok live streaming, with perceived usefulness and perceived enjoyment serving as mediating variables. This research employs a quantitative approach using a survey method involving 200 respondents who have previously purchased fashion products through TikTok Live. Data were analyzed using Structural Equation Modeling based on Partial Least Squares (SEM-PLS) with the assistance of SmartPLS software. The results indicate that interactivity and visual appeal have a positive and significant effect on perceived usefulness and perceived enjoyment. Furthermore, perceived usefulness and perceived enjoyment are found to have a positive and significant influence on impulse buying. Mediation analysis reveals that perceived usefulness and perceived enjoyment partially mediate the relationship between interactivity, visual appeal, and impulse buying. These findings emphasize the strategic importance of interactive features and visual presentation in live streaming in shaping consumers’ cognitive and emotional experiences that ultimately stimulate impulsive purchasing behavior.

Abstract

The development of lifestyle-oriented consumption and social values has driven significant changes in consumer behavior toward premium products. Stanley Tumbler has emerged as a symbol of social consumption that is perceived not only in terms of functional attributes but also through social value, brand trust, and brand reputation. This study aims to examine the effect of perceived social value on the competitiveness of Stanley Tumbler products in Indonesia, with brand trust and brand reputation serving as mediating variables. This study adopts a quantitative approach using a survey method conducted among consumers of Stanley Tumbler products in Indonesia. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results indicate that perceived social value has a positive and significant effect on brand trust and brand reputation. Furthermore, brand trust and brand reputation are found to have a positive and significant influence on product competitiveness. Mediation analysis reveals that brand trust and brand reputation significantly mediate the relationship between perceived social value and product competitiveness. These findings emphasize the importance of social value and brand perceptions as key sources of sustainable competitive advantage in the premium lifestyle product market.

Abstract

This study analyzes the effect of Transformational Leadership, Reward System, and Work-Life Balance on Employee Performance with Work Motivation as a mediating variable among Generation Z employees in Surabaya. Using a quantitative approach with cross-sectional design, data were collected from 200 respondents through Likert scale questionnaires and analyzed using SEM-PLS. Results showed that all three variables positively and significantly affect Work Motivation and Employee Performance, both directly and indirectly. Work Motivation acts as a partial mediator, explaining 62% of variance in employee performance. The structural model demonstrated substantial predictive power with R² of 62.2% for work motivation and 62.0% for employee performance. This study strengthens Self-Determination Theory in Indonesia's emerging market context and provides practical guidance for HR practitioners in designing transformational leadership strategies, adaptive reward systems, and work-life balance policies for Generation Z.
