The tight competition in the soap industry has caused Lux to experience a decline between 2020 and 2024 due to various factors. The purpose of this research is to examine the impact of Brand Image and Price Perception on consumers' choices when buying Lux brand soap products in Surabaya City. Employing a quantitative methodology, 110 participants were carefully chosen via a purposive sampling technique.

Abstract

Advancements in digital technology have driven significant changes in marketing activities, particularly in the food and beverage sector. Digital marketing has become a strategic approach that enables companies to reach consumers more broadly and effectively, while electronic word-of-mouth (e-WOM) facilitates the exchange of information and consumer experiences that can influence purchasing decisions. This study aims to analyze the effect of digital marketing and E-WOM on the purchase decisions of Kopi Janji Jiwa in Sidoarjo, motivated by the phenomenon of declining Top Brand Index scores amid increasingly intense competition in the coffee shop industry. This study employed a quantitative approach using purposive sampling technique involving 110 respondents who had purchased Kopi Janji Jiwa more than once and were residents of Sidoarjo. Most respondents were consumers aged 17–22 years who actively used social media, making them more responsive to digital marketing activities and online information. Data were collected through questionnaires using a Likert scale and analyzed using structural equation modeling-partial least squares (SEM-PLS) with the assistance of the SmartPLS application. The results indicate that digital marketing and e-WOM have a positive and significant effect on the purchase decisions of Kopi Janji Jiwa in Sidoarjo. These findings suggest that effective digital marketing strategies and positive consumer reviews on digital platforms can enhance consumer trust and encourage purchasing decisions. This study provides an empirical contribution to enriching consumer behavior studies, particularly regarding the role of digital marketing and E-WOM in influencing purchasing decisions within the coffee shop industry in Indonesia. Furthermore, the findings can serve as input for companies to optimize digital marketing strategies and manage E-WOM effectively.

Abstract

The increasing problem of plastic waste in Indonesia has encouraged retail industry players to introduce eco-friendly products such as eco bags as an alternative to single-use plastic bags. However, the declining sales of eco bags at Alfamart Sidoarjo during the 2023–2025 period indicates that the green marketing strategy implemented has not been fully effective in driving consumer purchasing decisions. This study aims to analyze the effect of green marketing, green perceived value, and price perception on the purchasing decision of eco bags at Alfamart Sidoarjo. This study employed a quantitative approach with purposive sampling technique involving 102 respondents, data collection through questionnaires, and data analysis using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 3 software. The results show that green marketing has a positive but insignificant effect on purchasing decisions, green perceived value has a positive and significant effect on purchasing decisions, and price perception has a positive and significant effect on purchasing decisions with the greatest contribution among the three variables examined.
