Abstract

The transition to electric vehicles (EVs) is a global strategy aimed at reducing greenhouse gas emissions and mitigating the adverse effects of climate change, particularly in the transportation sector. This study seeks to analyze the factors influencing the purchase intention of EVs in Jakarta, a region with a low adoption rate despite various governmental incentives. Employing a combined framework of the Theory of Planned Behavior (TPB) and the Technology Acceptance Model (TAM), the research examines the influence of attitudes toward EVs, perceived usefulness, perceived risk, environmental concern, and subjective norms on purchase intention. Additionally, moderating variables such as monetary incentives, non-monetary incentives, and personal norms are evaluated to understand their role in strengthening or weakening the relationships between independent and dependent variables. Data were collected through a survey of 300 respondents in Jakarta and analyzed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The findings aim to provide empirical insights to enrich the literature on environmentally friendly technology adoption and serve as a reference for policymakers and automotive industry stakeholders in formulating effective strategies to accelerate EVadoption in Indonesia.

Abstract

Social media marketing has become a key strategy for building relationships between brands and consumers. In the entertainment industry especially in K-Pop companies like SM Entertainment actively implement Social Media Marketing Activities (SMMAs) to boost fan engagement and influence purchasing decisions. This study aims to examine the effect of perceived SMMAs on purchase intention, brand loyalty, and impulsive buying among K-Pop fans in Indonesia, while considering the mediating roles of brand trust, brand experience, and brand love. The study focuses on K-Pop fans who are active on social media and interact with promotional content from SM Entertainment’s artists. Data were collected from 316 respondents via an online survey and analyzed using Structural Equation Modeling (SEM) based on the Stimulus–Organism–Response (S-O-R) framework. In this model, SMMAs act as the stimulus, brand trust, brand experience, and brand love serve as the organism, and purchase intention, brand loyalty, and impulsive buying represent the consumer response. The findings show that perceived SMMAs significantly influence brand trust, which in turn enhances brand experience and brand love. These three factors directly and sequentially impact purchase intention, brand loyalty, and impulsive buying. The results emphasize the importance of social media marketing strategies in shaping trust, emotional connection, and meaningful experiences that drive fan behavior. Practically, entertainment companies can use these insights to design more effective and emotionally engaging digital marketing strategies to stay competitive.
