In the face of competition and limited resources, the marketers shifting their focus from efforts to gain new customers on the efforts to retain existing customers, and of completing the deal "one shot" into securing customers' lifetime value [2,3].
Therefore, in the context of an increasingly competitive industry, customer loyalty is seen as a key factor in winning market share and to develop a sustainable competitive advantage. In the service industry, a typical feature requires an understanding of customer service, satisfying the needs and expectations, create, communicate and deliver customer value, and keeping promises [4].
Loyal customers are believed to be an asset for marketers, because the loyalty expected to persist in the long term. With the loyal customer, business marketers to find and develop new customers will be reduced.

Loyal customers will have an impact on repeat purchases, word of mouth recommendations, and customer resistance. Customer loyalty is the customer's intention to re-use the products offered marketers based on experience and their expectations in the past [9]. Loyalty is also a psychologically deep commitment to buy consistently repeated in the future despite attractive offers from competitors to switch brands. In this context, the fundamental question is how to create loyal customers, as well as what are the factors that affect customer loyalty? Understanding why or how customer loyalty continues to be one of the issues that are important marketing management services to date [10].
This article is a literature review of the factors that are the determinants of customer loyalty in the service industry. Empirical research on customer loyalty has been a lot done. However until now still not reached a consensus on the key factors that shape the loyalty of customers [11,12,13,14,15] showed that the main factor for the formation of a very complex and dynamic loyalty because customers are constantly changing and evolving over time. Therefore, Knox & Walker [13] suggested that need more research on this. A number of research shows that there are several factors that are antecedents of customer loyalty. In this article the variables that will be studied as a determinant of customer loyalty is the quality of service, price perception, the perception of value, brand equity, customer satisfaction, customer trust and customer commitment.

Service Quality
To achieve customer satisfaction, quality of service is an important determinant to be considered by the service provider. Because of the quality of the received or perceived as customer perception of overall quality or excellence of a product or service that is pleased with the intention expected. Quality of service related to customer Journal of Business and Management Sciences satisfaction. Correspondingly, the Rial et al. [16] stated that the quality of support services is very strong impact on satisfaction with the service provider. Thus, service providers should always be open and always learn to what the customer wants. If this is true then the customer satisfaction will be achieved. Empirical research Ravichandran et al. [17], Dai et al. [18], Shlash & Alhamdani [19], Mohammad & Alhamadani [20], Hu [21], Rahman et al. [22], Shpëtim [23], Zafar et al. [24], Ramseook-Munhurrun [25], as well as Madjid et al. [26] showed that customer loyalty can also be influenced by the quality of service.

Perceived Price
While the products, distribution, and promotion resulted in the expenditure of resources, the price is one of the elements of the marketing mix that directly affect the inflow of resources. For this reason, the activity is important for managers to organize and manage the price. To manage effective pricing decisions, marketing managers must seek to understand how consumers respond to price changes. For customers, the perceived price, which includes the time, effort and cost of the search, is more meaningful than the actual monetary price of goods and services. Customers usually as a judge in deciding the price and quality of service as well as generating satisfaction or dissatisfaction levels are based on the concept of "equity" [27]. In other words, in the evaluation of the reasonableness of the overall price, customers consider cost of the monetary and non-monetary acquire products or services [28,29,30].
Previously, Fornell, et al. [11] suggested that affects price perceptions of customer satisfaction. Similarly, Voss, et al. [31] suggested that satisfaction affects price perceptions. In addition, other studies also indicate that price is considered to be very important in determining the duration of the provider-customer relationship [32]. Because it can be said that the perception of price is one of the determinants of satisfaction, trust, commitment and customer loyalty [11,31,32].

Customer Perceived Value
Other factors that affect consumer loyalty is the value received by the consumer in any transactions with service providers. No high-value services by itself but must go through the process of creating value from the consumer. Customer value is a sense of joy and consumer evaluation of the product attributes, attributes of performance, and the consequences arising out of the use of facilities in achieving the goals and intentions of consumers in the situation that connect the product situation and consequences related to that experienced by consumers who are goal-oriented [33].
Values can be seen from a different perspective, from the perspective of normative-marketing strategies and consumer behavior-descriptive perspective. In a normative perspective of marketing strategy, customer value creation is one of the key elements for the success of a company. Meanwhile, from the perspective of consumer behavior descriptive, value is something desirable, useful or important. Therefore, people will be able to achieve some of their personal value through the possession or consumption of the product [34,35]. In this context, consumers buy products not for the sake of "transaction value" (the value of customers) but for the benefit of products that will satisfy their needs or personal values.
Customer value is a consequence of the subjective evaluation which is the sum of a variety of perceived benefits and costs, taking into account different factors. In other words, the perceived value of customers is the surplus (or difference) between the perceived benefits and costs, which refers to the subjective rate of return for the cost of customer perceived. Therefore, to establish customer loyalty is high, then a company must be able to deliver high customer value as well.

Brand equity is a series of brand assets and liabilities associated with a brand name and symbol that add or subtract a given value of a product or service to the company [5]. From this perspective, brand equity is formulated from the standpoint of managerial and corporate strategy, although the main foundation is consumer behavior. According to him, the brand equity can be valuable for the company (company-based brand equity) and the customer (customer-based brand equity). Services brand equity has been recognized as an important marketing construct.

An important reason for managing and developing their brand equity is more brand more meaningful than just products. Product dimensions only describes the attributes to be exchanged and easily imitated by other companies, while brand can explain the specific emotions and relationships with customers as well as the nature of intangible (intangible) that are not easily copied by competitors. The stronger the brand equity of a product, the stronger the appeal in the eyes of the consumer to choose the product motivated. To foster brand loyalty. If consumers believe that a particular brand is physically different from competing brands, the brand image will be attached on an ongoing basis so as to form a loyalty to a particular brand, which in turn will create customer loyalty [37].
Brand equity also affect the attitude and the confidence of consumers in making purchasing decisions, either because of past experiences in using the brand, as well as proximity to the brand and the various characteristics possessed by the brand. Brand equity is empirically also a determining factor of satisfaction, trust, commitment and customer loyalty [38][39][40][41][42][43][44][45][46].

Satisfaction is not enough if consumers are not turning back or be loyal.

[52] suggested that trust is a positive expectation on other parties in a risky situation, and trust can serve as a foundation based on any cooperation.
Trust has the basic elements of such trust in a partner or the other, based on the belief that positive expectations (without suspicion), and the relationship to risk between the two parties.

Therefore, trust is an important factor contributing to the development of relations and will affect customer satisfaction due to the marketing relationship [54].
