Abstract

This study aims to analyze the effect of product packaging, brand awareness on repurchase intention of Sumbawa Forest Massage Oil with consumer satisfaction as a mediating variable. This study uses a quantitative approach with a correlational research design. Data collection was carried out through a Likert-scale questionnaire distributed online to 200 respondents who knew and had purchased Sumbawa Forest Massage Oil at least once, selected using a non-probability purposive sampling technique. The variables studied included product packaging, brand awareness, repurchase intention, and consumer satisfaction. Data analysis was carried out using Partial Least Square-Structural Equation Modeling (PLS-SEM) with the help of SmartPLS 4 through evaluation of measurement models and structural models. The results showed that product packaging and brand awareness had a positive and significant effect on consumer satisfaction, brand awareness and consumer satisfaction had a positive and significant effect on repurchase intention, while product packaging had no effect and was not significant on repurchase intention, but consumer satisfaction was proven to be able to mediate the influence of product packaging and brand awareness on repurchase intention. This study shows that increasing brand awareness and consumer satisfaction is the main strategy in encouraging repeat purchases and sustainability of traditional medicinal product MSMEs, and provides a basis for policy making and further research development by adding other variables or expanding the study object to other traditional herbal products.

Abstract

The halal cosmetics industry in Indonesia is growing rapidly with a market value of USD 7.8 billion in 2022, but Timephoria customer retention in Mataram City is still below national standards, creating a research gap regarding the influence of celebrity endorsers and product quality on repurchase intentions moderated by consumer satisfaction. This study aims to examine this relationship to provide marketing strategy recommendations. Using a quantitative explanatory approach with a causal survey method and SEM-PLS, the population included Timephoria consumers in Mataram aged ≥17 years, with a sample of 250 respondents via purposive sampling through Google Forms on social media. The 5-point Likert scale questionnaire instrument was tested for validity (outer loading >0.7, AVE >0.5) and reliability (CR >0.7, Cronbach's α >0.7) using SmartPLS 4.0, analyzed through outer/inner models, R-square, and bootstrapping. The results show that product quality (β=0.369, t=4.283, p<0.001) and consumer satisfaction (β=0.489, t=6.131, p<0.001) have a significant effect on repurchase intention (R²=0.787), while celebrity endorser (t=1.178, p=0.239) and moderation are not significant. The conclusion recommends prioritizing halal product innovation and customer service for optimal retention.
