Keywords: Marketing Mix, Service Quality, Satisfaction, Loyalty, Tourists

1.     INTRODUCTION

Samosir is one of the largest lake in the world, and the largest and most popular in Indonesia. Samosir is located in North Sumatra area which is one of the valuable assets in the State/Local Government and is one of the important tourist destination after Bali and Lombok, so it is a pride for the region. The establishment of Samosir as one of the tourist destination, because the assumption of beautiful natural panorama (SIANTURI, 2004).

However, Samosir tourism activities are currently not experiencing developments, as seen from a decrease in the number of visitors so that tourism facilities are starting to be neglected (BUATON; PURWADIO, 2015). In Samosir tourism area, there are not only Samosir tourism object but also 4 other tourism objects, namely Batu Gantung, Kera Huta Sibatu Loting Tourism Park, Bangun Dolok and camping ground and also Dolok Simarbalatuk. These objects are in fact if developed properly can provide more value in Parapat tourism area, but the current conditions of these objects are almost unknown to the public (BUATON; PURWADIO, 2015). 

To manage the tourism industry properly and profesionally, an in-depth study is needed including tourists as the source of income that must be served well to keep them happy and comfortable so that the residence time within the tours area will be longer. The tourism industry is a type of product which is mostly engaged in the service, for all aspects related to the economic orientation are services (HIDAYAT, 2010).

The dynamics that occur in the tourism services sector can be seen from the development of various industries such as banking, insurance, telecommunications and others. Marketing services intended to build expectations of tourists and make a promise to the tourist (DARYANTO, 2013).

The company strives to meet the expectations and promises to tourists so that tourists are satisfied. Consumer satisfaction is the level of one's feelings after comparing performance (results) that perceived with the expectation (Daryanto, 2013). Tourists experiencing various levels of satisfaction or dissatisfaction after experiencing each services in accordance with the extent to consumer expectations are met or exceeded.

This is because satisfaction is the emotional state, the post-purchase reaction of tourists can be anger, dissatisfaction, irritation, neutrality, joy, or pleasure. Tourists who are angry or dissatisfied would cause problems because they can be moved to another company and spread the negative word of mouth (LOVELOCK; WRIGHT, 2007).

Many factors can affect tourist loyalty, including the marketing mix and service quality. It is supported by some research results of Azhar and Jufrizen (2017), and Gultom (2017), Setiawan and Sayuti (2017), Tefera and Govender (2017) stating that the service quality and marketing mix has a positive and significant effect on tourist loyalty. This studywas made aiming to replicate the study, because of the marketing mix and service quality effect on tourist loyalty.

a)   To Investigate the impact of the marketing mix on tourist satisfaction.

b)   To investigate the impact of service quality on tourist satisfaction.

c)    To Investigate the impact of the marketing mix on tourist loyalty.

d)   To investigate the impact of service quality on tourist loyalty.

e)   To investigate the impact of the tourist satisfaction on tourist loyalty.

f)     To Investigate the Mediation Role of Tourist Satisfaction on the Effect of Marketing Mix and Service Quality on Tourist Loyalty.

2.     LITERATURE REVIEW

2.1.        Loyalty

Loyalty is the willingness of tourists to continue the purchase on a company in a long period of time and use the product or service repeatedly, as well as recommend it to friends and other companies in voluntary (OLIVER, 2002).  While according to Griffin (2005) consumer loyalty is a concept of loyalty that leads more to behaviour than attitude and a loyal consumer will show a purchase behavior which is defined as a regular purchaser and shown over times by some decision making units. Loyalty is important concept in marketing because loyalty is one of the factors to be able to determine the market share of a company. 

Consumer loyalty is a behavioral drive to make purchases repeatedly and to build consumer loyalty to a product/service that is produced by a company that takes a long time through a repetitive purchasing process (OLSON, 1993).

Loyalty does not only mean the existence of consumer wishes to buy back the same brand in later time, but also the consumer have a psychological commitment or attitude towards the brand. And the loyal tourists are not only buy the brand but also refused to switch to other brands even though other brands offer something more than the brands they use (WELLS et al. 2003).

Loyal onsumers are not sensitive to price, deliver a positive recommendation regarding the brand and willing to spend more money on these brand-producing company (UNCLES, et al., 2003).  Loyalty can also refers to the preference of tourists to purchase a particular brand of a product category.  This occurs because tourists feel that a brand is able to offer the product features, product image or product quality level which matches to the price. Basically, the first time tourists will experiment in the purchase of a product, after they try the product and feel satisfied, they will make it a habit and will continue to purchase the same product because they feel the product is more secure and known (GIDDENS, 2002).

2.2.        Consumer Satisfaction

Johnson and Fornell (1991) stated that consumer satisfaction is the result of a thorough evaluation of the top performing consumer products which they consume. Yi (1991) identified two different concepts of customer satisfaction, namely transaction-specific satisfaction and overall satisfaction. Transaction-specific satisfaction is a concept that refers to the assessment of customer satisfaction after purchasing particular products or brands.

While overall satisfaction is a concept that measures the satisfaction (dissatisfaction) of tourists towards particular products or brands as a whole based on the entire experience in consuming these products or brands. Thus overall satisfaction could be viewed as a function of all transaction-specific satisfaction that occurred before.  In this study, the concept of customer satisfaction that used is overall customer satisfaction. By knowing the measurement results in consumer satisfaction, the company can prepare strategies that will be implemented in order to create consumer loyalty (HADIYATI, 2012).

Consumer satisfaction according to Kotler and Armstrong (2009) is the level of consumer feelings after comparing performance (or results) that the consumer perceive than their expectations. According to Hasan (2009) consumer satisfaction is a feeling of consumer in good response of products or services that has been consumed. In general satisfaction can be defined as a comparison between results received or services in consumer expectations, results received or services at least must be equal with consumer expectations, or even beyond it.

Kotler (2009) revealed that satisfaction is as feelings of like or dislike someone for a product after he/she compared a product performance with his/her expectations.  Simamora (2008) argues that customer satisfaction is the result of experience in the product. This is a consumer feeling after compare between expectations (prepurchase expectation) and actual performance.

2.3.        Marketing Mix

            Marketing mix is the set of controlled tactical marketing tools (products, prices, places and promotions) that combined company to produce the desired response in the target markets (KOTLER; ARMSTRONG, 2009).

            Daryanto (2013), the marketing mix is the tactical marketing tools that can controlled and combined by the company to produce the desired response in the target markets. Marketing mix is the variables to be monitored by the company to satisfy the groups targeted (CANNON, et al, 2008).

            Marketing mix consists of a product, is offered at a certain price, with some kind of promotion to tell prospective tourists about these products, and a way to reach consumer's place (CANNON, et al, 2008). Marketing mix consists of all the things that a company can do to influence the demand for its products (KOTLER; ARMSTRONG, 2009).

            Effective marketing program combines all the elements of the marketing mix into an integrated marketing program designed to achieve the company's marketing goals by delivering value for tourists. Marketing mix is the company's tactical advice to determine a strong positioning in the target markets (KOTLER; ARMSTRONG, 2009).

2.4.        Service Quality

            Service quality is the evaluation of tourists' long-term observationsin the service delivery of a company (LOVELOCK; WRIGHT, 2007). The definition of service quality is the magnitude of the difference between expectations or desires of tourists with their level perception (LAKSANA, 2008).

            According to Kotler and Keller (2009), service quality is a statement about the attitude towards the comparison between expectations and performances. Meanwhile, according to Lovelock, et al (2011), service quality is something that consistently meet or exceed consumer expectations.

            Also according to Ratnasari and Aksa (2011), service quality is how far the difference between reality and consumer expectations for services received/retrieved. While the Yamit (2010) stated that in general, service quality can be seen from the comparison between consumer expectations andservice performances. 

            The best service to customers and the level of quality can be achieved consistently by improving services and paying special attention to good service standard performance both in internal service standard or external service standard. Before the consumer buys a service, tourists have expectations about the service quality that is based on personal needs, experiences, word of mouth recommendations, and ad service providers. After buying and using these services, tourists compare the expected quality with what is truly received (LOVELOCK; WRIGHT, 2007).

3.     RESEARCH METHODS

The location of the study was carried out in the tourism destinations of Samosir Region, North Sumatra, located in seven districts namely Simalungun Regency, Toba Samosir Regency, Samosir Regency, North Tapanuli Regency, Humbang Hasundutan Regency, Karo Regency, Dairi Regency. The population in this study were all tourists who visiting the Samosir Region.

The sample used non probability sampling, allowing the opportunity for someone to be a respondent was not known. Sampling of tourists in this study was determined by quota sampling as many as 200 respondents either male or female. In this study, the sampling technique was accidental sampling, which was how to obtain samples based on tourists who was found when conducting the study, which was taken from the research site without distinguishing the origin of the tourists.

Data collection techniques used in this study includes interviews and questionnaires to the relevant parties. In its implementation, researchers get respondents by visiting respondents one by one, then asking their willingness to become respondents in this study, after the respondents are willing, the authors interview respondents one by one based on the prepared questionnaire.

The interview was carried out in the morning until noon when the visitors arrived. Before the questionnaire was distributed, validity and reliability tests were carried out first.. The technique of data analysis in this study is descriptive and Structural Equation Modelling (SEM)

5.     DISCUSSION

            Based on the results of factor analysis that has been presented in the previous chapter obtained that the variable which effect on tourists loyalty of Samosir Region in this study is the marketing mix, service quality and tourist satisfactions. The following is the linkages between variables, namely:

a)   Marketing Mix Effects on Tourist Satisfactions

Based on the results of the study showed that marketing mix has a positive and significant effect on tourist satisfactions in Samosir Region. The results of this study means that if the better implementation of marketing mix, it will increase tourist satisfactions. Conversely, if the weak implementation of marketing mix, the tourists will be dissatisfied.

According to Oliver (2002) loyalty is the commitment of customers to stay in depth to re-subscribe or re-purchase selected products or services consistently in the future, even though the influence of the situation and marketing efforts has the potential to cause behavior change. Empirically, the findings of this study supporting the study that was conducted by Rasyid et al., (2017), Teviana et al. (2017), Ismail et al. (2015) and Gultom (2017) which showed that marketing mix had an effect on tourist satisfactions. Meanwhile, the results of the study by Al Muala and Al Qurneh (2012) concluded that products had a significant effect on tourist satisfactions, while prices, people and processes had no significant effect on tourist satisfactions. The results of the study by Megatef (2015) concluded that all elements of the marketing mix had a very strong effect on tourist satisfactions.

b)   Service Quality Effects on Tourist Satisfactions

     Based on the results of the study showed that service quality has a positive and significant effect on tourist satisfactions in Samosir Region. The results of this study means that if the better implementation of service quality, it will increase tourist satisfactions. Conversely, if the weak implementation of service quality, the tourists will be dissatisfied. 

     A successful marketing program can be seen from its ability to satisfy the wants and needs of consumers. The combination of marketing mix elements was created to be able to meet customer satisfaction together. Previous research shows a variety of findings where not all marketing mix elements always affect satisfaction.

     Empirically, the findings of this study supporting the study that was conducted by Rasyid et al., (2017) concluded that service quality had a significant effect on tourist satisfactions.The results of this study also reinforce the results of previous study conducted by Setiawan and Sayuti (2017), Adinegara et al. (2017), Tefera & Govender (2017) who concluded that service quality had an effect on tourist satisfactions.

c)   Marketing Mix Effects on Tourists Loyalty

            Based on the results of the study showed that marketing mix has a positive and significant effect on tourists loyalty in Samosir Region. The results of this study means that if the better implementation of marketing mix, it will increase tourists loyalty. Conversely, if the weak implementation of marketing mix, the tourists will be not loyalGriffin (2005) stated his opinion about consumer loyalty is a concept of loyalty more towards behavior (behavior) compared to attitude (attitude) and a loyal consumer will show purchasing behavior that is defined as regular buyers and shown all the time by several decision-making units.

            Empirically, the findings of this study supporting the study that was conducted by Azhar and Jufrizen (2017), and Gultom (2017) who concluded that marketing mix had an effect on tourists loyalty. Meanwhile, the results of the study by Al Muala and Al Qurneh (2012) concluded that products had a significant effect on touristsloyalty, while prices, people and processes had no significant effect on tourists loyalty. Esmaili et al. (2017) who concluded that prices, physical evidence and distribution had an effect on tourist loyalty.

d)   Service Quality Effects on Tourists Loyalty

            Based on the results of the study showed that service quality has a positive and significant effect on tourists loyalty in Samosir Region. The results of this study means that if the better implementation of service quality, it will increase tourists loyalty. Conversely, if the weak implementation of service quality, the tourists will be not loyal.

            This research is in line with research conducted by Mohammed (2013), said that many organizations have realized that maintaining excellence depends on obtaining customer loyalty, because service quality is the material needed to convince customers to choose an organization than others.

            Achieving a high level of quality service provided is the importance of loyal customers. Providing high-quality services is considered the most effective way to ensure the superiority of hospitality services over its competitors by maintaining customer loyalty.The results of this study reinforce the results of previous study conducted by Setiawan and Sayuti (2017), Azhar and Jufrizen (2017), Tefera and Govender (2017) who concluded that service quality had an effect on tourists loyalty.

e)   Satisfaction Effects on Tourist Loyality        

            Based on the results of the study showed that satisfactions had a positive and significant effect on tourists loyalty in Samosir Region. The results of this study means that if the better implementation of satisfactions, it will increase tourists loyalty. Conversely, if the weak implementation of satisfactions, the tourists will be not loyal. Bowen and Chen (2001) state that customer satisfaction is closely related to customer loyalty, where satisfied customers will become loyal customers.

            Then the loyal customer will become a powerful marketing force for the company by providing recommendations and positive information to other prospective customers.The results of this study reinforce the results of previous study conducted by Setiawan and Sayuti (2017), Teviana et al. (2017), Azhar and Jufrizen (2017), Mohamad et al.. (2011), Tefera and Govender (2017), Suwunniponth (2013) and Gultom (2017) who concluded that tourist satisfactions had an effect on tourists loyalty.

·   The Mediation Role of Tourist Satisfaction on the Effect of Marketing Mix and Service Quality on Tourist Loyalty. Based on the testing of mediation variables, it is evident that the tourist satisfaction variable acts as an intervening variable for the effect of exogenous variables on the marketing mix and service quality on tourist loyalty. The test results show that to increase tourist loyalty, the determining factor is tourist satisfaction, service quality and marketing mix. Loyal consumers are consumers who have a behavior that supports a company, have a commitment to buy back the company's products or services and recommend products or services to other parties so that it can be said to be an extraordinary marketing tool for the company. They can provide recommendations and spread word-of-mouth that are positive about the company, can increase sales by buying other products from the company and will buy these products more often and only require a smaller cost to satisfy them because they already know the product and requires less information about the product (BOWEN; CHEN, 2001). This is in accordance with the results of research conducted by Azhar anf Jufrizen (2017), and Gultom (2017), Al Muala and Al Qurneh (2012), Setiawan and Sayuti (2017), Tefera and Govender (2017), Teviana et al. (2017), Mohamad et al.. (2011) and Suwunniponth (2013).
