Abstract: The purpose of this study was to test and analyze the effect of product quality, price, and packaging on customer loyalty for Mutiara Kediri Coffee. This research uses a quantitative approach where the research data is collected through a questionnaire. The research sample of 119 respondents was taken randomly using purposive sampling technique. The sample criteria used are customers who have bought Mutiara Coffee more than 2 times. The analytical method used in this study is multiple linear regression analysis. Data were collected through a Likert scale questionnaire to measure customer perceptions of product quality, price, packaging, and loyalty. Regression analysis reveals that product quality, price, and packaging all have a significant positive effect on customer loyalty. Specifically, higher product quality fosters greater commitment and repeat purchases, while competitive pricing and attractive, functional packaging also contribute to increased loyalty. The results of this study highlight that each of these factors independently influences customer behavior, and together, they significantly shape long-term customer retention. Keywords: Price.

Indonesia investment data in 2024 even notes that Indonesia is the third largest country in the world as a robusta coffee bean producer (Indonesia Investments, 2. In line with this, at the provincial level. East Java is currently building a coffee and processed coffee industry both on a local and international scale (Disperindag Provinsi Jawa Timur, 2. Meanwhile, in a smaller area. Kediri District is currently designing a program related to the expansion of added value and industrialization of coffee products because the growth of this product is very high. One of the coffee industry centers in Kediri is Mutiara Coffee. Kopi Mutiara was established in 2016 until now and has even opened thousands of jobs for the community. In the competitive business world. Mutiara Coffee continues to innovate to be able to meet the expectations of customers so as to create customer loyalty. Research conducted to explore the factors that influence Mutiara Coffee customer loyalty has been conducted where most of the responses from customers are around the factors of product quality . 7%), price . 3%), and packaging . %).

Meanwhile, in terms of price, customers consider that the price of Mutiara Coffee is still relatively more expensive when compared to competitors. In terms of packaging, customers often complain about the appearance of the coffee wrappers, as well as the absence of packaging in small sizes . Based on the results of the pre-survey, it is suspected that fluctuations in sales have occurred due to declining customer loyalty. So research is needed to examine the influence of factors such as product quality, price, and packaging on Mutiara Coffee customer loyalty. Literature Review Product Quality Product quality shows the totality of product features and characteristics that are able to provide satisfaction and fulfillment of consumer needs and desires (Taufik et al. , 2. Product quality is a set of characteristics and characteristics of a product in carrying out its function to meet consumer needs. When product quality cannot meet customer expectations, customers will feel dissatisfied and will then increase the likelihood of not repurchasing in the future (Wilson, 2. Product quality is also defined as the overall benefit of everything offered to a market which can be in the form of tangible goods, services, ideas or a combination of these things, which can meet the needs and desires of the target market (Firmansyah, 2018:. Based on these definitions, it can be concluded that product quality is the totality of the features of a product with all the benefits that the product can provide that can provide satisfaction and fulfillment of consumer needs. The quality of food and beverages products can be measured by indicators, namely taste, healthy option, diversity of choice, presentation, temperature, and freshness (Taufik et al. , 2. Price Price is the value of a product expressed in money that must be spent to get the product (Lutecia & Suryadi, 2. In addition, price is also an exchange rate that can be equated with money for the benefits obtained from a good or service (Sopiani & Ketut, 2. Price is also defined as the sum of all the values that consumers provide to get the benefits of owning or using a product or service (Kotler. , & Keller, 2021:. Price is one of the determinants of the success of a company because price determines how much profit the company will get from selling its products in the form of goods and services (Firmansyah, 2018:. Based on these definitions, it can be concluded that the price perception of a product is a consumer assessment expressed in money that must be spent to get the benefits of owning the product. In the field of food and beverages, the price variable has indicators including affordable price, quite clear price, accordance with the quality, and more affordable than competitor (Sopiani & Ketut. Packaging Packaging serves as a protective container for products, safeguarding them from damage and ensuring quality preservation (Mensah et al. , 2. It encompasses activities from design to production, playing a vital role in product presentation and functionality (Eka Damayanti et , 2. Packaging not only offers practical benefits but also conveys essential product information through labels, aligning with consumer needs while enhancing product appeal (Ratnapuri et al. , 2. The visual appeal of packaging significantly influences consumer perceptions, as it provides the first impression of a productAos quality. Well-designed packaging International Journal of Economics.

Unique and innovative designs can further increase a product's perceived value, demonstrating the critical role of packaging in shaping consumer behavior. Moreover, packaging contributes to a productAos image and directly impacts customer loyalty by influencing their views on product quality (Ratnapuri et al. , 2. Effective packaging should preserve the contents, be environmentally friendly, and offer convenience for users (Mensah et al. , 2. In conclusion, packaging is more than a protective measureAiit serves as a key marketing tool that shapes consumer perceptions, enhances product value, and fosters loyalty through its functionality and visual appeal. Customer Loyalty Customer loyalty is defined as a strong commitment from customers to continuously repurchase preferred products or services despite external influences or competing marketing efforts (Deby Gunawan & Romauli Nainggolan, 2. It reflects a consumer's voluntary and enduring preference for a product, brand, or company, driven by factors such as product quality and emotional attachment (Kotler & Keller, 2. Loyalty also includes providing positive feedback and recommending the product to others (Taufik et al. , 2. According to Hasan and Salim . , consistent product usage signifies loyalty, which reflects a long-term dedication to a specific product or service (Chaniago, 2. Wilson . emphasizes that perceived product quality significantly enhances customer loyalty by encouraging repeat Furthermore, loyalty entails both behavioral and attitudinal commitment, signifying not only repeat purchases but also a special preference for the product (Padillo Jr et al. , 2. Indicators of customer loyalty include regular repurchases, willingness to buy other products from the same company, readiness to recommend the product to others, and an overall sense of loyalty. In conclusion, customer loyalty stems from a firm and enduring commitment to a product or service, overcoming external factors and marketing pressures that might otherwise lead to switching behavior. It is influenced by the perceived quality of the product, emotional connection, and customer satisfaction, making it a critical factor for long-term business Research Hypothesis Relationship between Product Quality to Customer Loyalty Quality products will encourage consumer loyalty, even empirical studies on consumer behavior show that most loyal consumers are consumers who use quality products (Deby Gunawan & Romauli Nainggolan, 2. Quality products have an important role in shaping consumer behavior to remain loyal to a product. The higher the quality of the products provided, the higher the loyalty of the customers (Sopiani & Ketut, 2. The quality of a product sold to customers will foster a commitment that will be held firmly by customers, thus encouraging customer loyalty to keep buying the same product (Sahid & Abadi, 2. addition, quality products will provide a positive experience for customers, thereby encouraging loyalty from customers (Rochmah & Muzdalifah, 2. Product quality can also encourage a strong and firm commitment from customers to continue to choose these products despite the influence of various external factors and marketing initiatives that can usually encourage customers to change their habits in choosing products (Hasan & Salim, 2. This shows that quality products have a significant impact on customer loyalty. Furthermore, when customers are satisfied with the quality of the product purchased, they will tend to return to make repeat purchases in the future. Good quality creates a positive experience, which then International Journal of Economics. Bussiness and Accounting Research (IJEBAR) Page 152 International Journal of Economics.

Customers who are satisfied with the quality of a product also tend to recommend it to others as a form of customer loyalty to a product (Sadewa, 2. Several studies show that product quality has a significant effect on customer loyalty (Chaniago, 2020. Deby Gunawan & Romauli Nainggolan, 2024. Hasan & Salim, 2023. Rochmah & Muzdalifah, 2024. Sahid & Abadi, 2. H1: Product quality has a significant effect on customer loyalty Relationship between Price to Customer Loyalty Price is one of the factors that can increase customer interest in making repeat purchases in the future. When customers consider that the price paid is in accordance with the value they get, there will be a sense of satisfaction which ultimately leads to customer loyalty (Hutama & Ekawati, 2. Price is an important factor in consumer loyalty where the price of a product that is reasonable and in accordance with the value provided by the product will increase the perceived value of consumers of the product. Prices that are too high can reduce consumer loyalty, while prices that are too low can create the impression of low quality products (Sugiono et al. , 2. The results of the study found that prices that are affordable, and can compete compared to competitors, can increase customer loyalty (Rochmah & Muzdalifah, 2. Price also plays an important role in influencing customer loyalty where when the price of a product is perceived to be commensurate with the value received, customers tend to be satisfied and more likely to remain loyal to the product. Competitive and fair pricing can create a positive perception of the company, which in turn strengthens long-term relationships with customers. Furthermore, customers are even willing to pay more if they feel the product is worth the price, which shows that loyalty is not always related to lower prices, but rather to the value received (Sadewa, 2. Several studies have shown that price has a significant effect on customer loyalty (Hutama & Ekawati, 2020. Rochmah & Muzdalifah, 2024. Sopiani & Ketut, 2023. Sugiono et al. , 2. H2: Price has a significant effect on customer loyalty Relationship between Packaging to Customer Loyalty Packaging has become a very important marketing tool because in addition to protecting the contents of the product, it can also provide value for the product itself so that it provides attractiveness for customers which in turn can encourage customer loyalty (Ratnapuri et al. Sometimes the value of the product depends on the packaging, because the outer appearance is the first view of the consumer to the product. Good packaging can also influence the experience for consumers to then support consumer loyalty behavior to the product (Alamsyah et al. , 2. The visual quality of packaging such as color, packaging material, product information, and other elements can provide cues about quality product performance so that consumers remain loyal to the same product (Mensah et al. , 2. Several studies have shown that packaging has a significant effect on customer loyalty (Candrasa, 2019. Mensah et , 2022. Ratnapuri et al. , 2. H3: Packaging has a significant effect on customer loyalty Relationship between Product Quality. Price, and Packaging to Customer Loyalty Product quality, price, and packaging are factors that can affect consumer loyalty.
