Abstract

The textile industry has been a critical driver of global economic growth in recent decades. However, this growth is inextricably linked to its environmental impact. The textile industry causes significant environmental issues, including water pollution from dyes, high water usage, and greenhouse gas emissions. Understanding these specific environmental issues highlights the need to explore solutions, such as using eco-friendly clothing. This study aims to identify the factors that influence generation Z consumers’ preferences for eco-friendly clothing products in Indonesia by adopting the theoretical framework of the Information-Motivation-Behavioural Skills (IMB) model. The IMB model was chosen for its comprehensive approach to explaining how information and motivation, combined with behavioral skills, drive consumer actions, making it suitable for analyzing sustainable purchasing behavior. 201 generation Z respondents in Indonesia completed the survey using consecutive sampling. The data was then analyzed using structural equation modeling (SEM). The results showed a positive and significant influence between green self-concept and subjective norm on the purchase intention of environmentally friendly clothing. However, green clothing knowledge’s effect on purchase intention was not statistically significant. Further results found that green clothing self-efficacy can mediate the influence of green self-concept and subjective norm on green clothing purchase intention. However, green self-efficacy has not been proven to mediate the effect of environmental apparel knowledge on purchase intention.

Abstract

Green cosmetics are becoming increasingly popular as consumers' awareness of the environment grows. This study explores the relationship among Indonesian consumers' attitudes toward green cosmetics, environmental consciousness, behavioral control, subjective norms, product knowledge, purchase intention, and purchasing behavior. Data were collected from 310 respondents through an online questionnaire from various groups of men and women, then analyzed using Descriptive Statistical Analysis and SEM (Structural Equation Modeling). The research findings indicate that attitudes towards green cosmetics significantly influence purchase intention, and environmental consciousness also plays a crucial role in driving purchase intention. Perceptions of behavioral control and subjective norms also significantly affect purchase intention. Product knowledge has a significant impact on attitudes towards green cosmetics. Purchase intention significantly influences actual purchasing behavior. Exciting differences are observed between men and women. Environmental consciousness significantly impacts women's purchase intention, while behavioral control and subjective norms are more dominant in influencing men's purchase intention. The implications of this research are essential for producers and marketers of green cosmetics, offering insights for developing effective marketing strategies. This study highlights the importance of different approaches when targeting male and female consumers, considering the factors influencing their purchase intentions and behavior. These findings contribute to a deeper understanding of consumer behavior related to green cosmetics, encouraging environmentally friendly consumption patterns.

Abstract

The rapid expansion of sustainability marketing has increased the risk of greenwashing, raising urgent concerns about declining consumer trust and the effectiveness of environmental communication. As consumers become more environmentally aware, misleading green claims may not only fail to persuade but also actively undermine pro-environmental purchasing behavior. This study aims to examine how perceived greenwashing influences purchase intention by analyzing the mediating roles of consumer skepticism and brand trust, as well as the moderating role of environmental concern. Employing a quantitative, cross-sectional research design, data were collected through an online questionnaire from 340 adult consumers who had been exposed to environmental marketing claims. A purposive sampling technique was applied to ensure respondent relevance, and the data were analyzed using Partial Least Squares Structural Equation Modeling. The results demonstrate that perceived greenwashing significantly increases consumer skepticism and reduces brand trust, both of which mediate its negative effect on purchase intention. In addition, environmental concern strengthens these relationships, indicating that environmentally concerned consumers react more strongly to perceived inconsistencies in green claims. This study offers novelty by integrating signaling theory and attribution theory into a consumer-centric dual mediation model that explains why sustainability messaging can backfire when credibility is questioned. The findings provide important implications for marketers and policymakers by highlighting the need for credible, verifiable environmental communication and stronger governance of green marketing practices.

Abstract

Penelitian ini bertujuan untuk menginvestigasi peran mekanisme teknis dan keamanan dalam mendorong niat pembelian ulang pelanggan pada platform marketplace di Indonesia melalui kerangka kerja Technology Acceptance Model (TAM) yang diperluas. Secara khusus, studi ini mengevaluasi bagaimana persepsi keamanan, kemudahan penggunaan, dan manfaat penggunaan membentuk kepuasan dan kepercayaan pelanggan sebagai mediator perilaku pasca-pembelian. Menggunakan pendekatan kuantitatif, data dikumpulkan dari 231 responden yang merupakan pengguna aktif marketplace melalui survei daring dengan teknik purposive sampling. Data tersebut kemudian dianalisis menggunakan Structural Equation Modeling-Partial Least Squares (SEM-PLS). Temuan penelitian mengungkapkan bahwa kemudahan penggunaan merupakan stimulus utama dalam menciptakan kepuasan pelanggan, yang selanjutnya menjadi pendorong paling signifikan bagi niat pembelian ulang. Namun, hasil pengujian menunjukkan bahwa kemudahan teknis semata tidak mampu secara langsung membangun kepercayaan pelanggan tanpa dukungan jaminan keamanan transaksi dan manfaat fungsional yang nyata. Hal ini mengindikasikan pergeseran perilaku konsumen digital di Indonesia yang semakin rasional dan kritis dalam mengevaluasi nilai serta keamanan platform belanja daring. Penelitian ini memberikan kontribusi teoretis pada literatur adopsi teknologi serta strategi praktis bagi pelaku industri e-commerce untuk meningkatkan loyalitas pelanggan melalui penguatan integritas sistem dan manfaat fungsional. Keterbatasan dan arah untuk penelitian masa depan juga dibahas dalam studi ini
