Abstract

This study aims to analyze the influence of prices and payment methods on consumer purchase decisions at Sakinah Sukolilo Supermarket Surabaya. Changing shopping behaviors and the increasing use of digital payments encourage the need to evaluate both factors in the context of local retail. The study used a quantitative approach with a sample of 96 respondents obtained through the Cochran formula. Data were collected using a Likert scale questionnaire and analyzed through validity, reliability, classical assumptions, and multiple linear regression tests. The results of the study show that prices and payment methods have a positive and significant effect both partially and simultaneously on purchase decisions. An Adjusted R² value of 0.620 indicates that both variables explain 62% of the variation in purchasing decisions. Payment methods are the dominant variable with the highest beta coefficient value. These findings confirm that the ease and efficiency of digital payments and competitive pricing play an important role in increasing consumers' propensity to make purchases.

Abstract

This study is intended to investigate the impact of Digital Marketing and Electronic Word of Mouth (e-WOM) on Purchase Decisions, with Brand Image as a mediating variable in Fore Coffee consumers in Surabaya. This study applied a quantitative approach through causal methods, involving 100 respondents who had made transactions at Fore Coffee Sulawesi Street. The data was analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with the help of SmartPLS 4 software. The findings of the study show that Digital Marketing and e-WOM have a positive and significant effect on Brand Image and Purchase Decisions. Brand image also has a significant influence on Purchase Decisions. In addition, Brand Image has proven to be a partial mediator, so Digital Marketing and e-WOM continue to have a direct influence, but the effect increases when through Brand Image. The research model produced an R² value of 0.671, which indicates good explanatory ability of the model. Overall, this study emphasizes that strengthening digital marketing strategies, managing e-WOM, and building a consistent brand image is very important in improving consumer purchasing decisions of Fore Coffee.

Abstract

This study is intended to evaluate the impact of product differentiation and customer relations on the increase in organic fertilizer sales volume in the Sidoarjo Regency area. A quantitative approach was applied through a survey involving 120 participants, namely farmers and organic fertilizer traders in the area. Sample selection was carried out by stratified random sampling technique. Information collection was carried out through a questionnaire, then processed using multiple linear regression analysis with the support of SPSS software version 25. The findings of the study revealed that product differentiation had a significant positive effect on the increase in organic fertilizer sales, with a coefficient of 0.458 (p<0.05). Similarly, customer relationships showed a significant positive impact on the increase in sales, with a coefficient of 0.412 (p<0.05). Simultaneously, product differentiation and customer relationships contributed significantly to the increase in organic fertilizer sales, with a percentage of 71.6% (R² = 0.716), while the remaining 28.4% were influenced by external variables that had not yet been explored. This study suggests that organic fertilizer makers in Sidoarjo Regency continue to innovate in product differentiation and strengthen long-term ties with consumers to encourage higher sales.
