INTRODUCTION
The actions of businesses that provide both services and goods are directed toward the same end, namely, profit maximization. Additionally, the company strives to ensure that customers are satisfied with the items it produces, as customer satisfaction is a key indicator of a company's ability to generate high-quality products. One of the organizations can recognize the importance of the marketing component in producing the best and most appropriate marketing strategy to be implemented. Because marketing is one of the most crucial market opportunities in consumer considerations when making purchasing decisions for a product, it is critical to understand how marketing works. Without being attentive to the needs of consumers, it is almost guaranteed that the firm will lose many possibilities to acquire customers and that the items it offers would be in vain if it does not adapt its business practices.
Consumer demands are a crucial and primary issue for every business, and this is especially true in the convection business, given the fact that numerous convection enterprises are competing with one another to gain consumer loyalty and satisfaction. Providing excellent services or products at competitive prices will help the convection business build a solid and loyal customer base in this competitive environment, which will increase the likelihood of obtaining new customers in the long run. Satisfied customers are a strong indicator that these customers are likely to be loyal to the company and purchase from them again in the future ( (Farisi & Siregar, 2020); (Simanjuntak & Purba, 2020)).
Convection business is defined as a business field that manufactures clothing in large quantities based on demand. Due to shifting fashion trends as well as the function of clothes, the convection business is a very promising business sector with enormous profit potential. Clothing is not only a fundamental necessity, but it is also a way of life.

Behind the promising business potential, there are also problems faced by business actors, especially Fizzul Putra Mandiri convection in the form of fluctuations in raw material prices so that it affects production capacity and has the potential to cause business capital to shrink rapidly. This condition results in an increase in the price of convection products making it difficult to compete with competitors, especially imported convection, as well as from the consumer side who will turn to cheap and quality consumer products.
The importance of efforts to increase consumer loyalty is important to identify factors or variables that directly affect consumer loyalty. The first variable is product quality, which is a marketing strategy that seeks to differentiate a business's product or service from the competition (Ibad et al., 2018). Successful product quality begins with identifying and creating the unique qualities of the offering while observing the differences between the offering and competitors. Product quality goes hand in hand with developing a strong value proposition to make the product more attractive to the market.
