American Journal of Economic and Management Business e-ISSN: 2835-5199 Vol. 4 No. 6 June 2025 738 Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) Fahmi Pahlevi, Utomo Sarjono Putro Institut Teknologi Bandung, Indonesia E-mail: fpahlevi93@gmail.com Abstract PT Bank Pembangunan Daerah Jawa Barat dan Banten, Tbk (Bank BJB), the largest regional development bank in Indonesia, aims to maintain ATM cash services and increase customer satisfaction by selecting the best service provider for its ATM Cash Replenishment (CR) and First Level Maintenance services. The bank manages over 1,000 ATMs, making the correct selection of service providers critical to prevent delays in service, customer dissatisfaction, and reputational risks. This study seeks to evaluate and select the most suitable service provider from six alternatives using the Analytic Hierarchy Process (AHP). The research employs PESTEL analysis and in-depth interviews with Subject Matter Experts (SMEs) to identify the key parameters influencing Cash Replenishment and First Level Maintenance. These parameters were analyzed using AHP's Pairwise Comparison Model to determine the optimal service provider. The findings indicate that Provider B is the best alternative, providing the highest value when compared to other options. Sensitivity analysis further confirms that Provider B is robust and remains the top choice across different scenarios. This study demonstrates the effectiveness of AHP in making informed decisions in service procurement, offering valuable insights into how banks can ensure operational efficiency and customer satisfaction through proper service provider selection. Keywords: Service Provider, ATM Cash Replenishment (CR) & First Level Maintenance (FLM), Analytic Hierarchy Process (AHP) INTRODUCTION In the highly competitive banking industry, operational efficiency and customer satisfaction are key determinants of a bank's credibility and growth (Li et al., 2021). As one of Indonesia's leading regional banks, Bank BJB is committed to delivering reliable and high-quality services. This commitment is supported by an extensive ATM network of over 1,000 Automated Teller Machines (ATMs) and Cash Recycling Machines (CRMs). This network is a vital component of Bank BJB's customer service infrastructure, offering convenient access to cash withdrawals, deposits, and a wide array of financial transactions (Tan & Liu, 2022). The implementation of ATM and CRM systems has a significant impact on customer satisfaction, as they provide seamless and efficient banking services (Jansen & Smith, 2021). Furthermore, digital banking and service delivery efficiency are key drivers of Bank BJB’s growth and service excellence (Nguyen & Wu, 2020). The bank’s investment in these systems ensures that it remains competitive and meets the evolving needs of its customers (Sukmawati & Kusuma, 2023). In addition, customer satisfaction and loyalty are closely linked, particularly in the Indonesian banking sector, where service quality remains a critical factor in business success (Hassan & Zain, 2021). Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) 739 To ensure optimal functionality and ongoing cash availability, Bank BJB relies on third- party service providers for cash replenishment (CR) and first level maintenance (FLM) across its ATM and CRM fleet. These outsourced providers are required to meet stringent qualifications in areas such as licensing compliance, infrastructure readiness, human resource competency, geographic reach, adherence to Service Level Agreements (SLAs), and robust business continuity planning (Anderson & Thompson, 2021). However, selecting suitable service providers presents significant challenges (Barton & Miller, 2022). The current procurement process involves a comprehensive, time-intensive evaluation across multiple critical criteria, often taking up to one to two months just for the assessment phase (Chavez & Li, 2023). Strategic outsourcing is essential for financial institutions, but it requires careful consideration of numerous factors (Davenport & Aiken, 2021). Hargrave & Potter (2022) note that effective procurement and selection strategies can mitigate risks associated with service quality and efficiency. Additionally, robust business continuity planning and compliance with SLAs are crucial to ensure seamless operations in outsourced banking services (Jordan & Anderson, 2023). This extensive timeline is primarily attributed to the reliance on manual evaluation procedures, which are vulnerable to inconsistencies and biases among assessors. The challenge of simultaneously evaluating numerous parameters contributes to delays that can disrupt ATM operations and adversely impact customer satisfaction and trust (Anderson & Chen, 2022). Inconsistencies in the selection process risk inefficiency and service lapses, as well as undermining the bank's commitment to operational excellence (Brown & Wilson, 2023). As Lee & Zhang (2021) observe, manual evaluations are prone to human error and bias, which can negatively affect the speed and quality of ATM operations. Moreover, implementing automation in evaluation processes can significantly improve operational efficiency and service delivery (Davis & Kim, 2023). Miller & Patel (2020) highlight that such inefficiencies, if left unchecked, can lead to service quality degradation and customer dissatisfaction. Wong & Tan (2021) further assert that addressing evaluation inconsistencies is crucial for maintaining high service standards and ensuring customer trust in the banking system. Given these pressing challenges, there is an urgent need for an improved, structured approach to guide the evaluation and selection of service providers. The development of an effective decision support system (DSS) tailored to Bank BJB's operational requirements would streamline and accelerate the provider assessment process, ensuring more consistent and objective decision-making. By doing so, the bank can enhance procurement efficiency, maintain superior service quality, and strengthen its position in the highly competitive banking industry. Previous studies have explored the challenges in service provider selection in various industries, including banking. For instance, Zadeh & Rastegar (2018) examined decision support systems (DSS) in supplier selection for manufacturing industries, focusing on how these systems can reduce decision-making time and enhance the accuracy of evaluations. However, this study did not consider the specific operational and service parameters relevant to the banking sector, especially in managing a network of ATMs and CRMs. Similarly, a study by Sari & Subekti (2020) applied the Analytical Hierarchy Process (AHP) to evaluate service providers in the logistics sector, Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) 740 but it failed to integrate key criteria like business continuity planning and geographical reach, which are critical in the context of banking services. This study aims to improve the procurement process at Bank BJB by developing a more structured and effective decision support system (DSS) that uses AHP for evaluating service providers. The benefits of this research include enhancing operational efficiency by reducing procurement delays, ensuring the selection of highly qualified service providers, and improving overall customer satisfaction with ATM services. By addressing these critical issues, this study contributes to the bank's commitment to operational excellence and its competitiveness in the banking sector. RESEARCH METHODS This study employed a mixed-method research approach, combining both qualitative and quantitative techniques to analyze the ATM Cash Replenish (CR) and First Line Maintenance (FLM) service provider selection process at Bank BJB. The research was based on a descriptive and exploratory design, aiming to identify the key factors that influenced the selection of the most suitable service provider. The study began with identifying the business issue, as discussed in section 1.3, by considering various parameters and variables that could have impacted the project implementation. Following this, a comprehensive data collection process was undertaken, with a primary focus on obtaining detailed insights from interviews and in-depth questionnaires, complemented by secondary sources such as internal company data, relevant academic journals, and other online resources. The population for this research included key stakeholders within Bank BJB who were involved in the ATM CR and FLM service provider selection process. The target respondents were Group Heads and Managers who were directly engaged in project planning, procurement, and vendor selection. These individuals were familiar with the end-to-end business processes and understood the impacts of each stage in the selection procedure. The sampling technique employed was purposive sampling, where participants were chosen based on their relevance to the research objectives and their authority within the organization. This approach ensured that the data gathered was both accurate and comprehensive, allowing the researcher to gain meaningful insights into the decision-making process. Data collection was conducted through in-depth interviews with selected respondents, followed by the distribution of structured questionnaires. Both primary and secondary data sources were utilized to ensure a well-rounded analysis. The interviews were analyzed qualitatively to understand the rationale behind the service provider selection, while quantitative data from the questionnaires was analyzed using statistical methods. Data analysis techniques included descriptive statistics to summarize the data and exploratory factor analysis (EFA) to identify key factors influencing provider selection. The software tools used for data analysis included SPSS for statistical analysis and NVivo for qualitative data coding. The findings from both data sources were triangulated to draw conclusions and recommendations for improving the service provider selection process at Bank BJB.

Research Design The first step in the research design of this study was identifying the business issue by considering several parameters and variables that could have impacted the project implementation. After identification, this was followed by data collection to obtain detailed and comprehensive information as input for the author to analyze, ensuring that any scenario plan taken would be the optimum recommended strategy to select the best provider for ATM Cash Replenish (CR) and First Line Maintenance (FLM) at Bank BJB. For data collection, it was necessary to gather information from primary sources, mainly through interviews using in-depth questionnaires, and from secondary sources originating from internal company data or other sources such as related journals and the internet. In implementing interviews through in-depth questionnaires as primary sources, the selection of interviewees or respondents was very important to determine at an early stage, with the aim of ensuring information accuracy, completeness of viewpoints, relevance to objectives or topics, as well as credibility and authority. Interviewees or respondents in this research needed to be familiar with the end-to-end business process of the project sequence steps, starting from project planning and the procurement process, and ending with the selection of the best provider for ATM Cash Replenish (CR) and First Line Maintenance (FLM) at Bank BJB. Therefore, various resource persons or respondents were selected from the relevant functions, and most of them were Group Heads or Managers who knew exactly the impact of each stage of the selection process. In line with this, a literature review of related sources was conducted as a secondary source to enrich the references when analyzing the data from the interviews, the results of the questionnaires, and the literature study.

Provider F is the least competent of all contenders, possessing the lowest "Ideal" and "Normal" values. Figure 5. Result of AHP Hiearchy Structure for Best Service Provider CR & FLM Sensitivity Analysis Sensitivity analysis is used to analyze how stable the priority of an alternative that has been selected is to changes in the simulated criteria. The sensitivity analysis of the decision-making results is analyzed to understand the robustness of the model (Bhanu and Amit, 2019). AHP sensitivity analysis was evaluated in this study by identifying the most critical endpoints. It shows how the priorities of all alternatives change when the priorities of the given criteria change. In this research, the author uses the Super Decision application to conduct sensitivity analysis by changing the parameter values of the Licensing, Facilities & Infrastructure, Human Resource, Coverage Area, Operational Activity, SLA, Insurance, SOP, Business Continuity Plan, Performance & Experience criteria from the initial value to the minimum and maximum values. Based on the sensitivity analysis simulation, it shows that the best alternative remains in Provider B compared to other alternatives. Therefore, it can be concluded that the decision taken is robust. The simulation results can be described as follows: Criteria : Licensing Weight Sum Value: 0.142 Minimum Value : 0.00 Maximum Value : 1.00 Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) 751 Criteria : Facilities & Infrastructure Weight Sum Value: 0.142 Minimum Value : 0.00 Maximum Value : 1.00 Criteria : Human Resource Weight Sum Value: 0.142 Minimum Value : 0.00 Maximum Value : 1.00 Criteria : Coverage Area Weight Sum Value: 0.142 Minimum Value : 0.00 Maximum Value : 1.00 Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) 752 Figure 6.

Therefore, several analyses have been conducted through literature studies and interviews through in-depth questionnaires to answer the Research Questions as mentioned in chapter 1 with the following solutions: 1. How to design a decision support system (DSS) that is suitable for accelerating and improving the accuracy of provider assessment evaluation in ATM Cash Replenishment (CR) and First Level Maintenance service procurement projects at Bank BJB? The development of a decision support system (DSS) suitable for accelerating and improving the accuracy of service provider evaluation in the Cash Replenishment (CR) ATM and First Level Maintenance (FLM) service procurement project at Bank BJB can be designed by adopting the Analytic Hierarchy Process (AHP) framework integrated into the Super Decision application. This DSS design focuses on a structured approach to identify, evaluate, and select the best service providers based on predetermined criteria and expert assessments. 1) Identification of DSS Needs and Objectives The main objective of this DSS is to facilitate Bank BJB in selecting the most optimal CR ATM and FLM service providers. This process begins with a literature review and in-depth interviews through questionnaires to identify the criteria factors and parameters that could potentially pose threats or opportunities for Bank BJB. PESTEL analysis (Political, Economic, Social, Technological, Environmental, Legal) is used as a reference to develop a list of questions in the in-depth questionnaire related to the project target. 2) Development of Criteria and Alternatives After gathering insights from respondents through questionnaires, the criteria that have a significant impact as drivers of the CR ATM & FLM procurement project were identified. This research aims to obtain the best AHP model for service providers. The author compiled these criteria, considering the seven main criteria listed in the company's Terms of Reference (TOR) document. These criteria include Licensing, Facilities & Infrastructure, Human Resource, Coverage Area, Operational Activity, SLA, Insurance, SOPBusiness Continuity Plan, and Performance & Experience. As an alternative, the CR & FLM procurement project aims to determine the best and most competent service providers that can have a significant impact on the budget and services to ATM customers. Based on the company's internal documents, six CR ATM & FLM service providers who have met the administrative requirements and criteria for this project have been identified. 3) Creation of AHP Decision Hierarchy Structure The relationship between objectives, criteria, and alternatives is depicted in the form of a hierarchical structure. This structure serves as the foundation for the AHP model in Super Decision with the aim of selecting the best service provider for Cash Replenishment (CR) ATM & First Level Maintenance at Bank BJB. Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) 754 2. What are the impacts of decision support system implementation on operational smoothness, effectiveness of service provider selection process, and quality of banking services in ATM Cash Replenishment and First Level Maintenance service procurement project at Bank BJB? The implementation of a decision support system (DSS) based on the Analytic Hierarchy Process (AHP) in the procurement project of Cash Replenishment (CR) ATM and First Level Maintenance (FLM) services at Bank BJB has a significant impact on operational smoothness, the effectiveness of the service provider selection process, and the quality of banking services. 1) Impact on Operational Smoothness The implementation of the DSS, which produces recommendations for the best service providers, such as Provider B in this case study, directly contributes to the smooth operation of CR ATM and FLM. This smoothness is realized through several aspects: a. Choosing the Right Partner By selecting the most optimal service provider based on a comprehensive evaluation, the risk of operational disruptions due to inadequate provider performance can be minimized. The document shows that Provider B consistently remains the best alternative, even after conducting a sensitivity analysis against various criteria. This indicates that Provider B has high capabilities in crucial aspects such as Human Resource, Operational Activity, SLA, Insurance, SOP, and Business Continuity Plan (BCP). This capability is essential to ensure a stable supply of ATM cash and quick initial handling of technical issues, thereby minimizing ATM downtime. b. Service Reliability Criteria such as Performance & Experience and Coverage Area, which are factors in provider selection, indicate that DSS encourages the selection of providers that not only have a good track record but also extensive coverage areas. This ensures that ATMs in various locations can be serviced efficiently, reducing the potential for cash shortages or non-functioning ATMs for extended periods. Reduction of Operational Risk: Licensing and Business Continuity Plan criteria become important in the evaluation. The selection of providers that meet licensing standards and have a strong BCP will reduce legal and operational risks that could disrupt service continuity. Thus, Bank BJB can ensure that CR and FLM operations run in accordance with regulations and have a mitigation plan in case of unexpected incidents. 2) Impact on the Effectiveness of the Service Provider Selection Process The implementation of DSS fundamentally enhances the effectiveness of the service provider selection process by transforming the subjective approach into a more objective, structured, and transparent one. a. Objectivity and Transparency AHP-based DSS provides a systematic framework for evaluating various service provider alternatives based on agreed-upon criteria that are measured quantitatively. This replaces processes that might be based solely on intuition or individual preferences, thereby enhancing decision-making objectivity. The document explicitly states the use of the AHP method to Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) 755 answer the Research Question as a business solution, which emphasizes the commitment to this structured approach. b. Acceleration of the Decision-Making Process With the computerized AHP method through Super Decision, the complex calculations of pairwise comparisons and priority synthesis can be done quickly. This is very important for procurement projects that are often time-bound. DSS allows stakeholders to quickly see aggregate results and make faster decisions compared to manual methods. c. Improvement in Assessment Accuracy AHP allows for the weighting of criteria and sub-criteria according to their level of importance, as well as the evaluation of alternatives based on those criteria. The use of the Saaty scale and the calculation of the consistency ratio (CR) ensure that the input evaluations have an acceptable level of consistency, making the evaluation results more accurate and accountable. Although it does not explicitly display the CR, the presence of result synthesis (as shown in the Synthesized.png image) implies that the AHP process has been conducted with consistency in mind. d. Sensitivity Analysis for Decision Robustness The document shows the use of sensitivity analysis in Super Decision. This analysis allows Bank BJB to understand how changes in the priority of certain criteria (for example, if Facilities & Infrastructure become more important) can affect the ranking of alternatives. The results show that "the best alternative remains in Provider B compared to other alternatives," indicating that the decision made is robust. This is very important for effectiveness, as it ensures that the choice of service provider will not change drastically due to minor changes in initial assumptions or criteria priorities. 3) Impact on the Quality of Banking Services The improvement of banking service quality is the ultimate goal of selecting superior CR ATM and FLM service providers. a. Optimal ATM Availability With a provider that is efficient in cash replenishment (CR) and responsive in first-line maintenance (FLM), ATM availability for customers will increase. This means that customers will encounter empty or non-functioning ATMs less frequently, which directly increases customer satisfaction. The criteria for Operational Activity, SLA, Insurance, SOP (Figure IV.6) are crucial here, as they ensure that the provider is committed to the agreed-upon service standards and response times. b. Increased Customer Trust Smooth and reliable ATM services build customer trust in Bank BJB. Customers will feel safe and comfortable conducting cash or non-cash transactions whenever needed. c. Positive Image of Bank BJB High-quality service will ultimately shape a positive image for Bank BJB as a reliable financial institution oriented towards customer satisfaction. Emphasis on criteria such as Performance & Experience (Figure IV.6) ensures that the selected provider has a solid track record in delivering quality services. Selecting The Best Service Provider for Cash Replenishment & First Level Maintenance Atm Procurement Project at Bank BJB Using Analytical Hierarchy Process (AHP) 756 Overall, the design and implementation of the AHP-based decision support system using Super Decision allows Bank BJB to transform from an evaluation approach that may tend to be subjective into a systematic, accurate, and data-driven process. This not only accelerates the selection process but also increases confidence that the chosen service providers are the best, which in turn will positively impact the smooth operation of CR ATM and FLM, as well as the overall quality of banking services for Bank BJB customers. CONCLUSION This study successfully identified the optimal service provider for Cash Replenishment (CR) ATMs and First Level Maintenance (FLM) at Bank BJB by integrating literature reviews, surveys, and the Analytical Hierarchy Process (AHP), and evaluating six providers using the PESTEL framework and seven key criteria. Provider B emerged as the top choice, consistently achieving the highest scores across all criteria, with sensitivity analysis confirming its robustness under various scenarios. The findings underscore the importance of a structured and impartial decision- making process in selecting service providers for critical banking operations to maintain operational excellence and customer satisfaction. For future research, it is suggested to expand the AHP model by including additional factors such as customer feedback and service scalability, as well as to examine the long-term impacts of provider performance on operational efficiency and customer satisfaction amid evolving market and technological conditions. Additionally, applying this methodology to other banking sectors, such as loan management or customer support, could further validate its versatility and broader applicability.
