The result shows that intrinsic and extrinsic product attributes, sales promotion, and place influence purchase intention significantly, while price and advertising are not significant. From the gap analysis, the perceived performance of Product X on four significant elements is lower than the expectation.

The competition in Indonesia's courier, express, and parcel market has been very tight. J&T Express, one of the courier companies in Indonesia, needs to improve itself to survive and gain more market share.

Data from 104 respondents who have ever used the service of J&T Express and watched the content of J&T's social media content were collected and analyzed using PLS-SEM. The result shows that social media marketing, brand image, and purchase intention significantly influence brand loyalty.

On the other hand, purchase intention significantly mediates the impact of brand image on brand loyalty.

Abstract

With the widespread adoption of digital technology and the emergence of various smartphone brands worldwide, this research explores how these brands should adapt to the current consumer demands, particularly in a developing country like Indonesia. Gen Z has played a significant role among other generations in the Indonesian smartphone market, particularly favoring luxury brands like the Apple iPhone. Given the limited existing research on luxury consumption behavior in this market, this study aims to investigate the factors influencing the purchase intentions of Indonesian Gen Z consumers towards Apple iPhones. The research will discuss the significance of attitude, subjective norms, and perceived behavioral control in shaping consumer purchase intentions. Eighty responses were gathered from Generation Z who knew about the Apple iPhone and live in Indonesia. The study will use PLS-SEM to prove the research hypotheses using a quantitative approach with a simple random sampling method. The findings of this study highlight the pivotal role of subjective norms as the primary determinant of purchase intentions for Apple iPhone products. Furthermore, the subjective norm moderates the relationship between attitude and perceived behavioral control on purchase intentions.

Abstract

The surge in social media users has instigated profound shifts in societal interactions. Brands are now compelled to prioritize customer engagement on social media to influence purchase intention, thereby boosting overall sales and revenue. This study specifically analyzed the mediating role of customer relationships in the relationship between social media marketing activities and purchase intention. The research was centered on people in Indonesia who have seen Tokopedia’s Instagram content. Employing a simple random sampling approach, a questionnaire was disseminated, and subsequently, the PLS-SEM method was applied to evaluate the responses from 119 valid participants. The results showed a notable impact of social media marketing activities on purchase intention and a significant correlation between customer relationships and purchase intention. Additionally, the findings suggest that customer relationships partially mediate the connection between social media marketing activities and purchase intention.
