Abstract

The development of e-commerce in Indonesia is increasingly rapid. This development has an impact on very tight competition not only in almost all industries in the Indonesian economy, including the Micro, Small and Medium Enterprises (MSME) sector which sells products or services online, but also competition between companies providing marketplace platforms or applications. . The aim of this research is to assess the impact of customer satisfaction and increasing customer satisfaction on loyalty. This research is quantitative. Sampling was based on certain criteria, namely students in Yogyakarta who used marketplace applications. The sample size was taken using the Cochran formula. So a sample of 350 students was obtained. Data collection through questionnaires accommodated via Google Form. The data that has been collected is then subjected to initial testing, namely validity, reliability, basic assumption test and classical assumption test. After the data is deemed appropriate, the research hypothesis is then tested using a multiple regression test. The result is that customer satisfaction influences student loyalty in using marketplace applications by looking at a significance value of less than 0.05. Increasing customer satisfaction influences student loyalty in using the Marketpalace application as evidenced by a significance value of less than 0.05.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) continue to grow rapidly in Indonesia, where Word of mouth (WOM) and pricing factors play an important role in influencing consumer purchasing decisions. In the culinary industry, WOM is considered a more credible source of information compared to advertising because it comes from the experiences of customers who have directly tried the product. Meanwhile, competitive pricing becomes an essential factor in purchasing decisions, especially in the food industry, which is highly sensitive to price changes. This study aims to analyse the influence of WOM and pricing on purchasing decisions at the Ayam Goreng Pak Kuwadi business in Klaten. Using a quantitative approach, this study involved 30 respondents selected through purposive sampling. The results show that both WOM and pricing have a positive and significant influence on consumer purchasing decisions. Based on these results, it is recommended that business owners optimize their WOM strategies by creating positive customer experiences and implementing pricing policies that match the product quality to improve customer satisfaction and loyalty. This study provides practical guidance for culinary business owners in developing more effective marketing strategies to strengthen their competitiveness in the market.
