INTRODUCTION The Financial Services Authority (OJK) encourages banking digitalization by issuing OJK regulation No. 12 / pojk. 03 / 2018 concerning the Implementation of Digital Banking Services to Commercial Banks, states " digital banking services are electronic banking services developed by optimizing the use of customer data in order to serve customers more quickly, easily and according to customer experience and can be carried out independently by taking into account security aspects", with the existence of regulations from the OJK, it means that, the digital transformation carried out by the banking industry is more than just online and mobile banking services . Service quality is the level of excellence in service performance (Zeithaml et al. , 2. and is seen as an important success factor for companies to differentiate themselves and be competitive in the market. (Hossain et al. , 2021 . Parasuraman et al. , 1985, 1. Internet banking, a form banking electronic , is a portal where clients could utilise various service banking like To do payment bills and investments (Raza et , 2. Besides that , the bank faces many competition in attract and retain customers and for fight that , they must provide service quality Internet banking height that can be direct they for get superiority (Raza et al. , 2. According to Bank Indonesia (BI) data, e-money transactions in the last five years, namely 20172021, total e-money transactions increased, this caused the banking industry to become one of the business sectors that managed to have maximum performance. This study reinforces the importance of digital customer service as an outstanding cutting-edge technology to improve customer service efficiency (Andrade al, 2. Presentase E-Money 90,003,848 167,205,578 292,299,320 432,281,380 575,323,419 TAHUN TAHUN E-Money Presentase Figure 1 Circulating Electronic Money Transaction Instruments Source : https://w. id/id/statistik/economics of finance/ssp/uang-elektronik-sum. Based on graph 1, it can be explained that the phenomenon related to the use of technology applications in the world of e-money banking for five years has increased this is due to users or customers feeling the benefits and ease of transactions. Repair digital technology in design service banking could increase response emotional customer (Levy, 2. Indonesian banks are adopting technology, namely information and communication technology (ICT), to automate banking procedures (Alisjahbana et al. , 2. Perceived ease of use is defined as the extent to which a person believes that using a particular technological system will be effortless (Pratama et. By prioritizing excellent services and the precautionary principle for technology users, user confidence will be higher in the use of technology , perceived usefulness and perceived ease of use are the main factors that can increase user confidence to adopt technology applications to improve performance, increase productivity levels, and and effectiveness of users at work. In the banking industry, bankers are paying attention to the mobile shift of their customers as smartphones, tablets and applications are Management Research Studies Journal Volume 3 .

Rina Marlina L, increasingly being used in consumers' daily lives for work, study, entertainment, shopping. (Omoge et al. Innovation technology contemporary this have significant impact _ profitable sector commercial , allowing banks to give more service _ good to customer (Farah et al. , 2. The application of technology applications to banking products is a transformation of existing products and made into a variety of digital media products. The literature on digital banking services mainly focuses on aspects of technology adoption (Levy, 2. Service digital banking has fully change how banks run the business (Ahmed et. al, 2. One of the banks that has implemented a technology application system, namely Bank Mandiri as Livin' by Mandiri, which was published in October 2021, has become Bank Mandiri's main product for the retail segment that offers various advantages, namely financial services that are integrated in one application product, as well as an ecosystem platform. User intentions will be great when they believe that using technology applications will improve performance and other benefits. Thus, the application of technology applications has been trusted by customers to conduct business or other transactions using e-money . Customers will easily switch to another bank if they don't get what they expect, but when customers feel that their expectations and needs are being met when using a product or service, the customer will feel satisfied and make a transaction. The main key to winning customers' hearts or customer satisfaction according to research results from ( Wulan et al, 2016 . Saiti et al. , 2. , concluded that by providing value and satisfaction to consumers or customers through service quality, the use of information technology and product variations will increase the level of customer satisfaction. Figure 2 The Four Best App Performers of 2020-2021 (%) Source : Bank Service Exellence Monitor (BSEM) Based on the table above, according to BSEM, out of the 10 . best mobile banking performances. Bank Mandiri is in 4th . place after Bank BNI and Bank BCA which have the best mobile banking According to BSEM. Bank BNI and Bank BCA have high interest due to the variety of products launched by banks to complement services through digital technology applications. Bank Mandiri is known to have the latest application called Livin'by Mandiri, an application with a variety of products that will connect customer needs very easily https://bankmandiri. id/livin . Bank Mandiri's performance is still below other commercial banks, this shows that the level of customer or customer satisfaction with Bank Mandiri's applications is still low compared to other banks because decisions in the application of information technology applications and product variations are related to service performance to customers. Work behavior of bank employees or customer service does not affect customer satisfaction in using bank products due to several factors, including education level, local culture, and attitudes of application Management Research Studies Journal Volume 3 .

Product variety has long been a topic of interest in the operations management and marketing literature (Sweeney et al. , 2. In the operations management literature, there are two main streams. The first examines how product variation strategies . oth breadth and dept. are used to increase sales, market share, and by extension financial performance . g Kekre and Srinivasan, 1990. Ton and Raman, 2010. Wan and Sanders, 2017. Boada-Collado and Martnez-de-Albeniz, 2. The second focuses on the operational complexities introduced when firms employ product proliferation strategies . g Fisher and Ittner, 1999. Alfaro and Corbett, 2003. Wan et al. Application of Technology Application With the advent of foreign banks and financial deregulation, has become very competitive and no retail bank can afford to be second in its application of its technology to customer service (Rees, 1.

Construct this used for predict various factors , such as check intention user for adopt system or technology new , intention sustainable user for measure website and wireless usability , technology new , technology communication (Abdul Rahim et al. , 2. Perceived Ease of Use (PEU) is element important from adoption technology and use sustainable (Abdul Rahim et al. , 2. Davis . describes PEU as " the degree to which a person's believe that use system certain will free from effort , i. e easy understood or used Ay (Jen & Hung, 2. This is construction important in studies system information ( Bilgihan . Barreda . Okumus , & Nusair , 2016. Foroughi et al. , 2.
