This study investigates the impact of Brand Image and Price on Purchase Decisions at Takoyaki Janda, Raun–Raun Food Park, Pekanbaru, using a sample of 67 respondents. Data were analyzed via multiple linear regression, hypothesis testing, and determination coefficient calculation using SPSS 25. Findings reveal that both Brand Image and Price exert significant partial effects on purchase decisions, as well as a significant combined effect.

2026-01-29T12:25:58+07:00

This study investigates the mediating role of work motivation in the relationship between work environment, job stress, and employee performance at the General Bureau of the Riau Provincial Government. The research adopts a confirmatory and explanatory approach to examine causal relationships among variables based on established theoretical frameworks in human resource management. A saturated sampling technique was applied, involving all 100 employees of the General Bureau as respondents. Data were analyzed using Structural Equation Modeling with the Partial Least Squares approach (SEM-PLS) through SmartPLS 4.0. The results indicate that the work environment has a significant positive effect on work motivation and employee performance, while job stress has a negative influence on both motivation and performance. Work motivation is proven to play a crucial mediating role, strengthening the positive impact of a supportive work environment on performance and buffering the adverse effects of job stress. These findings suggest that employee performance in the public sector is not only shaped by structural and psychological working conditions but is also strongly driven by the level of internal motivation. This study contributes to the literature by providing empirical evidence on the integrative model of work environment, job stress, motivation, and performance within a provincial government context. Practically, the findings imply that public sector managers should prioritize the creation of a conducive work environment, effective stress management, and motivational enhancement programs to improve employee performance and organizational effectiveness.

This study aims to examine the effects of leadership and entrepreneurial characteristics on business performance, with interpersonal communication serving as a mediating variable among Micro, Small, and Medium Enterprises (MSMEs) in Telukjambe Timur District, Karawang Regency. The study population comprised 147 MSME actors, from which a sample of 105 respondents was selected. A descriptive quantitative approach was employed, and Structural Equation Modeling (SEM) was used to analyze the relationships among the variables in the proposed research model. The findings reveal that leadership and entrepreneurial characteristics have positive and significant effects on interpersonal communication. Furthermore, both leadership and entrepreneurial characteristics positively influence business performance. Interpersonal communication also demonstrates a positive effect on business performance and plays a significant mediating role in the relationship between leadership, entrepreneurial characteristics, and business performance. These results highlight the importance of effective leadership, strong entrepreneurial traits, and interpersonal communication in enhancing MSME performance.

2026-02-08T15:39:00+07:00

This study examines the effects of investment knowledge, risk perception, and income on students’ investment interest at the Faculty of Economics and Social Sciences, Universitas Islam Negeri Sultan Syarif Kasim Riau, Indonesia. A quantitative research design was employed, with primary data collected through questionnaires administered to 99 students selected using proportionate stratified random sampling. The data were analyzed using multiple linear regression with SPSS. The findings reveal that investment knowledge and income have positive and statistically significant effects on investment interest, whereas risk perception does not exhibit a significant influence. The coefficient of determination (R²) of 0.838 indicates that the proposed variables explain 83.8% of the variance in students’ investment interest, while the remaining 16.2% is attributable to other factors not included in this model. These results underscore the importance of strengthening financial literacy and improving students’ income capacity to enhance investment participation. Meanwhile, risk perception appears to be less influential, possibly due to students’ greater emphasis on expected returns. This study contributes to the empirical literature on investment behavior among university students and provides practical implications for higher education institutions and policymakers in promoting investment awareness and financial education.

Brand Trust, Audience Engagement, and Interactivity as Determinants of Purchase Decisions in TikTok Live Commerce

2026-02-09T10:03:10+07:00

The rapid growth of live streaming commerce has transformed consumer purchasing behavior, particularly among Generation Z users of TikTok Live. This study aims to examine the effects of brand trust, audience engagement, and interactivity on purchase decisions among TikTok Live consumers in Pekanbaru City. A quantitative research design was employed, with data collected through a structured questionnaire from 120 respondents who had previously made purchases via TikTok Live. The data were analyzed using multiple linear regression to test the proposed hypotheses. The results indicate that brand trust and audience engagement have a positive and significant effect on purchase decisions. These findings suggest that consumers are more likely to make purchasing decisions when they trust the brand and actively engage with live streaming content. In contrast, interactivity was found to have a positive but insignificant effect on purchase decisions, indicating that interactive features alone do not directly drive purchasing behavior without the support of trust and engagement. Overall, the research model explains 61.4% of the variance in purchase decisions. This study contributes to the literature on live streaming commerce by highlighting the dominant roles of brand trust and audience engagement in shaping purchase decisions within the TikTok Live context. Practically, the findings provide insights for marketers and sellers to focus on trust-building strategies and engagement-driven content to enhance sales performance in live streaming environments.
