Abstract

This study aims to examine the effects of Stress Level, Lifestyle, and Self-Control on Purchasing Decisions of Kopi Kenangan among Generation Z in Jabodetabek area. A quantitative approach was employed using a survey method with purposive sampling, and the data were analyzed using Partial Least Square–Structural Equation Modeling (PLS-SEM). The results indicate that Stress Level has a positive and significant effect on Purchasing Decisions, suggesting that higher stress encourages consumers to make purchases as an emotional coping mechanism. Lifestyle also shows a positive and significant influence, indicating that Kopi Kenangan consumption is closely related to the lifestyle and social activities of Generation Z. Meanwhile, Self-Control has a positive but insignificant effect on purchasing decisions, implying that self-control does not significantly restrain purchasing behavior in this context. These findings contribute to consumer behavior studies and provide practical insights for marketing strategies targeting Generation Z.

Abstract

In the context of higher education, academic achievement serves as a key indicator of students’ success in the learning process. This achievement reflects the outcomes individuals attain through their cognitive, emotional, and behavioral efforts. This study aims to examine the influence of organizational involvement, participation in Student Activity Units (UKM), and economic conditions on the academic performance among Pradita University Students during the 2023/2024 Term.. A quantitative approach was employed using a survey of 41 respondents who were active members of both campus organizations and UKM. The data were analyzed using SEM-PLS with SmartPLS 4. Respondents were selected through purposive sampling based on the criterion of being involved in campus organizations and UKM during the 2023/2024 period. The findings indicate that organizational involvement and economic conditions have a significant positive effect on academic performance, whereas participation in UKM does not show a significant impact. The research model explains 43% of the variance in academic performance, reinforcing that external factors such as organizational activity and economic stability play an important role in supporting students’ academic success.

Abstract

The purpose of this study is to evaluate the impact of research variables such as content marketing, influencer credibility, and online customer reviews on consumers' purchase intention of the Lozy hijab brand within the TikTok Shop ecosystem. This research was initiated due to the phenomenon of uneven fluctuations in purchase intentions across various dimensions, which calls for a more consistent digital marketing strategy. By adopting a quantitative methodology, this study applies a non-probability sampling technique using purposive sampling. The sample size determination refers to the theory of Hair et al., (2019) using a 5:1 ratio against 36 research indicators, resulting in a total of 180 participants. Data collection was done by distributing questionnaires to TikTok users who meet the specific research criteria. The empirical findings confirm that all independent variables contribute positively and significantly to triggering the dependent variable, which is purchase intention. Further analysis highlights that influencer credibility is the strongest determinant affecting the purchase intention of Lozy hijab products. Visual appeal and competence in message articulation have proven to be effective tools to convert audience attention into purchase intention. Based on these conclusions, this study is expected to serve as a strategic reference for Lozy hijab management to optimize future promotions. The company is recommended to curate collaborations with influencers who can authentically represent aspirational values, to ensure alignment between the lifestyle portrayed and market preferences.
