KEY WORDS

Service quality, trust, commitment and customer loyalty.

Nowadays, global competition is inevitable phenomenon in the business world. It is marked by fast changes in communication industry, information, and technology. The same goes for a banking sector.

The effect of competition at Indonesian banking industry was that in 1997-2000 there were tens of banks liquidated and the rest were merged since the continuously loss experienced by several banks either stated or private-owned lender. Customer trust towards national banking drastically decreases and causes the number of customers withdraw their funds from those banks. This incident shows that in managing bank it should be executed professionally by considering the problem faced by banking sector, i.e., (1) Bank has to pursue growth and expansion, (2) Bank is demanded to give an accurate and high service, (3) technological advancement, (4) funds structural change, and (5) competition.

Such complexity of the problems in the banking world rise to challenge for banking growth such as management guidance, the quality of service and knowledge about the marketing of banking services. Determination of service strategy and bank performance is extremely important to be paid attention. When customer trusts with performance offered by bank, then he/she will pay it with perform transaction repeatedly.

A high level of bank competition lets the customers free to decide, so that bank has to be willing to give the most appropriate service like the customer wants. Additionally, today's customer demands are various at which supported by higher educational background and easiness to get information, thus his/her demand and flexibility becomes high too. Pace, safety, convenience and friendliness in service are more required by customers to decide an option of banking service aside from interest rate, price rate and affordable cost of service. For that reason, bank competing each other tries to improve its service quality in order to fulfill customers demand.

The same goes for BPD Sultra Main Branch which has to compete with other banks operating in Kendari area. According to the Banks Performance Rank issued by Bank Indonesia Kendari Representative Office in December 2010, the rank of BPD Sultra upon commercial banks in Kendari is in the second position of 15 commercial banks based on the number of loan to deposit (DPK) coming from saving, credit transfers, and deposits. From the

DPK BPD Sultra above, amount of DPK from BPD Main Branch contributes 41.08% of the amount of the whole DPK. This means that a half of DPK at BPD Sultra is owned by BPD Sultra Main Branch. However, DPK got during 3 years (2009-2011), shows that growth of saving funds is still categorized to be small compared to deposits and credit transfer.

As the biggest branch office and supported by facilities and more complete personnel, BPD Sultra Main Branch should be able to get higher DPK from community. Creation of good service can be damaged by bad service delivery or marketing system. Since the negative publication of the service, BPD Sultra Main Branch tries to clear things away in order to improve the service so it can enhance customer trust and commitment that in the end will improve customer loyalty to bank.

But then the influence of service quality on trust and commitment and its effect on customer loyalty is sometimes different. Several previous studies shows gap in the result. Agung (2006) found that service quality has significant influence over the loyalty, while Parawansa (2012) discovered that it has not direct significant effect upon the quality but being mediated by trust, satisfaction and commitment. Furthermore, Ndubisi (2006) found that trust and commitment has significant influence to increase customer loyalty, and Handayani (2008) discovered that trust did not increase loyalty significantly. In other words, even though customer trusts to company, it does not mean that he/she is loyal too.

According to the explanation above, thus this study tries to learn the influence of service quality, customer trust, customer commitment and its effect on customer loyalty.

CONCEPTUAL FRAME AND HYPOTHESIS

Service quality is critical to hold customer to make him stay. Bank has to try it best to create and improve its customer loyalty by providing quality service. The service quality consists of completeness and physical appearance of service at bank (tangibles), fast and accurate process of service (reliability), the way bank officer serves customer is responsive, polite, and friendly (responsiveness), ensuring the confidentiality of customer data, problem solving as sworn, and the sincere attention (empathy) shown by bank officer to customer's complaint. The whole form of this service is meant to fulfill needs, desires and wishes of customer.

The customer faith that bank able to meet their need, desire and wish raises the sense of belief to bank. Trust does not just come but it has to be cultivated in a long term and in every event at which the customer uses the bank service. Bank has to make customer sure that product or service offered is fit to the need and wishes of customer, and bank has good reputation to keep data secret and is consistent in giving and maintaining service quality provided.

When customer trusts in bank performance and reputation grows, the opportunity to get customer using banking service is higher. Customers will more choose to save their funds at a bank which has big benefit and good reputation which will protect them from risk. This trust factor becomes a fundamental thing which has to be paid attention by bank since this kind of business is a trusty business. Once bank is able to gain customer trust, then at that time it gets his/her loyalty. In line with the trust that is grown continuously by bank, later on it will shape strong commitment from customers to maintain good relationship with bank. As a result, trust is critical to be considered since it becomes an element giving positive influence towards customer commitment. Customer trust is shown by attitude or behavior that is related to bank. A committed customer will always have and build invaluable relationship in the exchange he/she does. It happens since customer feels a big benefit in that exchange so they will always be there in the cooperation relationship. The existence of customer in the partner exchange is proven with their identity using product and service offered by bank. In addition, the loyal customer will kindly tell their positive experience related to the product and service that has been accepted to the other sides. In a long term it will increase bank reputation.

Having a loyal customer is a dream of every bank. The key to get is through fulfilling desires and wishes. The more banks can fulfill the customer desires or even over his/her

expectation, the more customers does not want to move to another bank and s/he will be more committed to use bank's service at which it shows customer loyalty to bank. For that reason, the improvement of service quality at BPS Sultra Main Branch brings positive influence.
