Evaluating User Satisfaction of IT Services Through Service Quality Approach

.


INTRODUCTION
In the context of globalization and rapid advancements in information technology, the use of Information Technology (IT) in the educational environment has become increasingly crucia [1,2].Higher education institutions, such as universities, are increasingly reliant on IT systems and services to support various academic and administrative activities [3].At Atma Jaya Catholic University (Unika Atma Jaya), a renowned institution of higher learning, the implementation of quality IT services is a key element in ensuring smooth operations and user satisfaction [4].However, this technology still shows inconsistency, requiring further integration with related functional units.Several information systems remain underutilized, creating gaps in meeting user satisfaction [5].
Biro Sistem Teknologi dan Informasi (BSTI) plays a key role in overseeing various information systems, including the Atma Jaya mobile application (known as AIDA) for attendance tracking, the Oracle PeopleSoft Campus Solutions platform (known as MyAtma) for course planning (Kartu Rencana Studi, KRS), access to academic information through the official website of Unika Atma Jaya, and Wi-Fi facilities available at various locations on the Unika Atma Jaya campus.
The importance of user satisfaction assessment regarding IT services is crucial in measuring the success of technology implementation in the Unika Atma Jaya campus environment, and it can also serve as feedback for BSTI to enhance IT services further [6].Therefore, this research aims to evaluate the level of user satisfaction with IT services at Unika Atma Jaya using a service quality approach method.This approach details the evaluation based on generally recognized service quality dimensions such as responsiveness, reliability, assurance, empathy, and physical aspects (tangibles).
Through the analysis of user satisfaction with IT services using the service quality framework, it is expected to identify detailed aspects that can be improved and points of excellence that need to be maintained.Thus, the findings of this research are anticipated to provide valuable input in efforts to enhance Ingénierie des Systèmes d'Information Vol 29., No. 2, April, 2024, pp. 637-648 Journal homepage: http://iieta.org/journals/isithe quality of IT services on this campus.Furthermore, the research findings are also expected to offer insights to other higher education institutions facing similar challenges, contribute to the continuous development of IT services in higher education, and strengthen Unika Atma Jaya's position as an innovative and responsive educational institution to technological advancements.

STATE OF THE ART
An analysis is a study that uses information that can be used to conclude, so it can be interpreted that analysis is an activity of conducting a discussion on an object whose next stage is to use data processing, after which conclusions can be drawn [7].The analysis is also about studying existing systems to design new plans or update existing ones [8].From the above definitions, we can conclude that analysis is the research stage of studying a system, which aims to find problems that arise and facilitate the system design stage-an activity to describe and find solutions that someone does to look at an object in detail [9].

Information system satisfaction
A system can be defined as a set of procedures, methods, and ways of working that are carried out to achieve a specific goal [10].Information is a form of data processed to perform a particular purpose.Data is still "raw" information and needs to be processed further to be used and utilized [11,12].How it is processed, and the type of data used depends on each institution's description and needs [7,13].There are several system characteristics, such as System components that make up the system, also known as subsystems [14].System boundaries are parts that describe one system with another plan [15].This system limitation can also be called the system boundary or scope [16].

Academic information system
The academic information system is designed to manage educational information by applying hardware or software technology so that the work process can be carried out correctly and precisely and become helpful information.This system's purpose is to support educational institutions' management system so universities can provide more appropriate, reasonable, and practical information services for users [17].

Service quality
Service Quality (Servqual) is a service quality that can be defined as the difference between the reality of the service received by customers and customer expectations.[18].The Servqual method is a commonly used method for measuring service quality [19].The concept of service quality is an evaluative factor that reflects consumer perceptions of five specific aspects of service performance [20,21].The satisfaction index with the Service Quality method is Tangibles, Reliability, Responsiveness, Assurance, and Empathy [22].
Servqual calculations are obtained by indicating each variable.Either perception variables or expectation variables were obtained from questionnaires distributed to consumers or expected variables [23].The results of the respondent's evaluation are processed to determine the Servqual score.The Servqual model employs a multi-dimensional scale to assess service quality, encompassing customer expectations, perceptions, and gaps in order to measure and identify areas of improvement [24,25].To obtain the desired data, the operational research variables are shown in Table 1.Ease of access, Comprehension

Related works
The previous research conducted by Maryana evaluated the quality of the website of the Faculty of Economics and Business at University X in Indonesia using the Importance Performance Analysis (IPA) method.This study yielded the highest performance score for the Information Quality variable at 3.86 and the lowest for the Usability variable at 3.75 [26].This research shares similarities with a study conducted in terms of the research case, which is a university.However, this study has a broader scope, focusing not only on the website but also on various other applications and Wi-Fi services within the IT service domain.Another difference lies in the methodology employed, namely the Service Quality (Servqual) method.The choice of the Servqual method for this study was driven by its emphasis on customer satisfaction measurement for each variable, whereas the IPA method prioritizes variables based on importance and performance values.
Another study by Putri measured IT performance using the Servqual method to explore the expected service perceptions from the Information Systems Unit at University X.Despite annual evaluations through balanced scorecards and satisfaction questionnaires, the results were contradictory.Therefore, a reevaluation was conducted using the Servqual method, concluding that immediate action was needed in dimensions such as inadequate physical facilities like hardware and software, and processes related to academic activities, such as system access failures, card recording errors, and student attendance list inaccuracies [27].This research contributes to the field by advocating for the use of the Servqual method in measuring IT service performance at a university to avoid incongruent results.

Research methodology
Research Stages to analyze IT service user satisfaction using the Service Quality (Servqual) method, as set out in the stages of the Figure 1.
The selection of SERVQUAL (Service Quality) as the primary instrument for evaluating service quality and satisfaction at Campus 3 of Atma Jaya University is based on its excellence that distinguishes it from similar tools.SERVQUAL is known for its comprehensive and multidimensional approach, covering five key dimensions that detail critical aspects such as responsiveness, reliability, assurance, empathy, and tangibles [18].This excellence is highly relevant when assessing the complexity of IT services in a university environment.The customer-centric focus of SERVQUAL provides a strong foundation, ensuring assessments align with user expectations and perceptions, particularly in the context of IT services in higher education.
Another advantage that reinforces the selection of SERVQUAL is its ability for benchmarking and gap analysis [28].This instrument allows for comparisons between perceived and expected service quality, providing concrete guidance for service improvements based on user needs [29].The reliability and validity of SERVQUAL across various industries affirm confidence in this instrument, while its customizable and universal nature indicates its suitability for evaluating IT services in a campus environment.Thus, the choice of SERVQUAL has a positive impact on measuring service quality and satisfaction at Atma Jaya University, providing a solid foundation for a thorough understanding of the delivery of IT services in the context of higher education.

The measurement scale used to generate quantitative data is the Likert Scale.The Likert Scale measures individual agreement or disagreement with program plans, program performance, or the level of program success [31].The Likert Scale is also used to measure individual or group perceptions, attitudes, or opinions about an event (see Table 8).Strongly Disagree 1

Data collection
The population is an area that already consists of objects or subjects with some capacities with specific characteristics studied by researchers and conclusions drawn about the people [32].The population in this study are active users of Unika Atma Jaya IT services, such as Lecturers and Active Students, for the population of active users of Unika Atma Jaya IT services is up to 10,000 people.
The sample is called part of the total population in a study.The following are the sample criteria for this study: 1. Active users of IT services at Unika Atma Jaya; 2. Have used IT services in terms of software and hardware at Unika Atma Jaya; 3. Respondents are willing to become research subjects.
This research employs a probability-based sample selection method.Probability sampling holds a particular advantage in research methodology due to its capability to afford each element in the population a known and non-zero chance of inclusion in the sample [33,34].This ensures equitable representation, allowing researchers to generalize findings to a broader population with a higher level of confidence [35].The sample collection is based on feedback from questionnaires distributed through university mail.The minimum required sample size is calculated using a crosssectional approach, as depicted in Eq. ( 1): Keterangan: : jumlah sampel : skor z pada kepercayaan 95% = 1.96 : derajat kepercayaan : maksimal estimasi = 0.5 : alpha (0.05) atau sampling error = 5% The result of the sample calculation using Eq. ( 1) by inputting a population value of 10,000 can be calculated as follows: = 1.96 2 × 0.5(1 − 0.5) × 10,000 0.05 2 (10,000 − 1) × 1.96 2 × 0.5(1 − 0.5)  = 369.98 (2) The result of the sample calculation using the crosssectional formula yielded a sample size of 369.98 respondents, rounded up to 370 respondents.For the questionnaire distribution, user information such as faculty, gender, and region was collected.The total number of respondents in the questionnaire distribution was found to be 372 respondents.

Wifi environment
Wifi measurements were taken at Building A at Campus 3 Unika Atma Jaya (at BSD) using the speed test application tool to get the results from Figure 3.

Wi-Fi dBm measurement
Wi-Fi Analyzer is a software that can measure the signal strength received through a cellphone so that it can see the power of the signal being tested by looking at the signal quality level scale by Table 9.
In the lake area (5.0 GHz access point).It can be seen from the Figure 4 that if the atma-student Wi-Fi has a signal strength of -93 dBm, then the lake area signal strength is fair.
In the canteen area (5.0 GHz access point).It can be seen from the Figure 5 that if the atma-student Wi-Fi has a signal strength of -93 dBm, then the signal strength of the lake area is fair.
In the park area (5.0 GHz access point).It can be seen from the Figure 6 that if the atma-student Wi-Fi has a signal strength of -73 dBm, then the park area signal strength is good.

RESULT AND DISCUSSION
The following are the research instruments used in collecting data.Researchers will use 98 statements based on the Servqual dimension and the Likert Scale to measure each piece of information presented to respondents.The design of the statements in the questionnaire is taken from the indicators determined in Servqual.In this study, researchers used 5 variables (X) consisting of Tangible (X1), Reliability (X2), Responsiveness (X3), Assurance (X4), Empathy (X5) and 6 indicators of the variable (Y).So the number of indicators obtained is 98 statements.Based on Figure 7, from the sample that has been taken, Figure 7(a) 372 respondents for the faculty grouping each respondent, the most samples who filled out the questionnaire are the Faculty of Economics and Business as much as 24%, the Faculty of Medicine as much as 26%, the Faculty of Engineering as much as 18%, the Faculty of Technology as much as 9%, the Faculty of Administrative Sciences and Communication Sciences as much as 8%, the Faculty of Law 6%, the Faculty of Psychology 5%, and the last is the Faculty of Education & Languages as much as 4%.Then Figure 7(b) of the sample in terms of gender, the overall selection is male 55% & female 45%. Figure 7(c) is divided into 3 groupings of campus areas from each respondent.The most samples filling out the questionnaire are the Semanggi area, as much as 45%, then the Bumi Serpong Damai (BSD) area, as much as 30% and after that, the Pluit area, as much as 25%.

Normality test
The sig value of Kolmogorv-Smirnov with the Monte Carlo approach is 0,217, which means that the confidence level is greater than 0,05 (0,217 > 0,05), and it is concluded that this sample data shows the normal distribution [36] (see Figure 8).

Validity test
The validity test is conducted to help ensure that the measuring instrument indeed measures what is intended or accurately gauges, so that the results can be reliable and relevant [37].After testing the validity using SPSS 26.0, all statements given to respondents are declared valid, and data processing can be carried out.The following is a validity test of each piece of information in the questionnaire for each dimension: (1) Tangibles: range of person correlation 0,211 -0,590 with R Table 0,10, the tangibles variable is said to be Valid.

Reliability test
Reliability testing evaluates the constancy and dependability of measurements or instruments employed in research.This process guarantees that the measurements produce dependable results consistently, both over time and across various conditions [38].This study uses Cronbach's Alpha coefficient formula.Variables can be declared reliable if they have a Cronbach's Alpha value > 0.60, and the results obtained from the 6 variables above that the Cronbach alpha value > 0.60, so the reliability test for the 6 variables above is declared reliable [39].Reliability test result can be seen on Table 10.

Multicollinearity test
The multicollinearity test looks at the Tolerance Value and VIF (Variance Inflation Factor).The trick is knowing or not there is a multicollinearity test deviation by looking at the Tolerance value > 0,10 and the VIF value < 10 [40].If later the multicollinearity test results are declared not to occur, the predictive power is stable, and vice versa.If the data processing results turn out to be multicollinearity, the predictive power may not be reliable, so later, it may also not be stable.Multicollinearity test result can been seen on Table 11.

Heteroscedasticity test
Suppose the correlation between the independent variable and the residual reaches a significance greater than 0.05 (Sig > 0,05).In that case, there is no heteroscedasticity problem, and from the 5 variables above the sig value> 0.05, it is stated that there is no heteroscedasticity (see Figure 9).

Multiple linear regression test
From the coefficients test results above, it is known that the regression coefficient (β) of the six variables on Tangibles is 0.194, Reliability 0.211, Responsiveness 0.079, Assurance -0.296, Empathy 0.008 (see Figure 10).

Figure 11. ANOVA test result
Based on the results of the SPSS output above, it is known that the R Square value is 0.522.It can be concluded that 52.2% of the variables Tangibles (X1), Reliability (X2), Responsiveness (X3), Assurance (X4), and Empathy (X5) can explain changes in Satisfaction (Y) and the remaining 47.8% which they think is influenced by other factors outside the variables that have been studied (see Figure 12).12, the regression coefficient (β) for the Tangibles (X1) variable in relation to Satisfaction (Y) is 0.195.The obtained F-value is 27.487.Moreover, the Tangibles variable demonstrates a significance value of 0.000, which is lower than 0.05 (0.000 < 0.05).This indicates a significant relationship between the variables examined in this study.The T-value is 4.197, exceeding the T-table value of 1.97 (4.197 > 1.97), thereby leading to the acceptance of the hypothesis.Therefore, it can be concluded that Tangibles (X1) have an influence on Satisfaction (Y).This can be interpreted as some applications of Unika Atma Jaya do not yet have a sufficiently good user interface design and fail to provide clear information on app usage.Additionally, the lack of adequate computer facilities and WiFi accessibility for all users contributes to the impact on satisfaction.
(2) In reference to the coefficient test results, the regression coefficient (β) for the Reliability (X2) variable with respect to Satisfaction (Y) is 0.212.The obtained F-value is 27.487.Furthermore, the Reliability variable exhibits a significance value of 0.001, which is less than 0.05 (0.001 < 0.05).Consequently, the variables used in this study display a significant relationship.The T-value is 3.323, surpassing the T-table value of 1.97 (3.323 > 1.97), leading to the acceptance of the hypothesis.Thus, it can be concluded that Reliability (X2) influences Satisfaction (Y).It can be concluded that some applications of Unika Atma Jaya are unable to provide accurate and reliable information.Furthermore, computer facilities and Wifi accessibility should be easily accessible at any time.These factors have implications for user satisfaction.
(3) According to the aforementioned coefficient test, the regression coefficient (β) for the Responsiveness (X3) variable in relation to Satisfaction (Y) is 0.078.The obtained F-value is 27.487.However, the significance value for the Responsiveness variable is 0.251, which exceeds 0.05 (0.251 > 0.05).This indicates an absence of a significant relationship between the variables examined in this study.The T-value is 1.150, smaller than the T-table value of 1.97 (1.150 < 1.97).Hence, the hypothesis is rejected, signifying that there is no influence between Responsiveness (X3) and Satisfaction (Y).Observing that Unika Atma Jaya has provided clear Standard Operating Procedures (SOP) regarding constraints in accessing applications and facilities, where users must follow the specified procedures.This is what causes Responsiveness not to have an impact on Satisfaction due to timing issues.
(4) Based on the provided coefficient test, the regression coefficient (β) for the Assurance variable (X4) in relation to Satisfaction (Y) is -0.297.The obtained F-value is 27.487.For the Assurance variable, the significance value is 0.000, which is less than 0.05 (0.000 < 0.05).This indicates a significant relationship between the variables examined in this study.The calculated T-value is -3.542, exceeding the T-table value of 1.97 (-3.542 > 1.97).Therefore, the hypothesis is rejected, suggesting that there is no influence between Assurance (X4) and Satisfaction (Y).This can be seen in the fact that Unika Atma Jaya's application has provided services according to user needs and instilled a level of confidence in user data protection rights.Therefore, this can be interpreted as Assurance having a negative impact on Satisfaction.
(5) As per the provided coefficient test, the regression coefficient (β) for the Empathy variable (X5) in relation to Satisfaction (Y) is 0.009.The obtained F-value is 27.487.In regards to the Empathy variable, the significance value is 0.919, which is greater than 0.05 (0.919 > 0.05).This implies that the variables examined in this study do not exhibit a significant relationship.The calculated T-value is 0.102, smaller than the T-table value of 1.97 (0.102 < 1.97).Therefore, the hypothesis is rejected, suggesting that there is no influence between Empathy (X5) and Satisfaction (Y).Usually, IT support provides service-related information regarding the availability or issues concerning applications and facilities through email.This information typically does not have a high level of urgency and is not a common problem, so it does not affect Satisfaction.
The calculation results indicate that user satisfaction with IT services at Unika Atma Jaya show that the Tangibles and Reliability variables have a significant positive impact on user satisfaction, while the Responsiveness variable does not have a significant influence.Moreover, the Assurance variable shows a significant negative impact, whereas the Empathy variable does not demonstrate a significant influence on user satisfaction.

CONCLUSIONS
This research addresses the issue of user satisfaction evaluation with Information Technology (IT) services at Atma Jaya Catholic University (Unika Atma Jaya), with a specific focus on the dimensions of service quality.The approach used in this study is the Service Quality (Servqual) model, successfully assessing user satisfaction with IT services at Unika Atma Jaya using the variables Tangibles (physical evidence), Reliability, Responsiveness, Assurance, and Empathy.
Upon a comprehensive examination of the test results, it becomes evident that certain dimensions of service quality have varying impacts on user satisfaction within the Unika Atma Jaya environment.Particularly, the Tangibles and Reliability dimensions emerge as significant contributors, indicating a positive and statistically significant impact on user satisfaction.This is evident from the significant values of Tangibles and Reliability variables, which are 0.000 and 0.001, respectively, with T-table values of 4.197 and 3.323.This suggests that improvements or enhancements in tangible aspects of service, such as facilities and physical evidence, as well as reliability in service delivery, can substantially increase overall user satisfaction.Conversely, the Responsiveness dimension, although tested, does not show a statistically significant impact on user satisfaction as it has a significant value of 0.251 and a T-table value of 1.150.This indicates that users' perceptions of prompt service delivery may not be a determining factor in their overall satisfaction.Interestingly, the Assurance dimension, while having the potential to build trust, demonstrates a significant negative impact on user satisfaction.The Assurance variable has a significant value of 0.000 and a T-table value of -3.542.This implies that careful management of aspects related to assurance is crucial to avoid negative effects on overall user satisfaction.Additionally, the Empathy dimension does not show a significant impact on user satisfaction with a significant value of 0.919 and a T-table value of 0.102.This indicates that empathetic understanding of user needs may not be a major factor in shaping user satisfaction in this context.
In conclusion, a nuanced approach to improving service quality, focusing on enhancing tangible aspects and reliability while addressing challenges related to assurance, appears crucial in optimizing the user satisfaction landscape at Unika Atma Jaya.This conclusion provides a deep understanding of the aspects that need improvement to ensure better IT services at Unika Atma Jaya, emphasizing tangible aspects, reliability, and special attention to managing the Assurance dimension.Suggestions for Unika Atma Jaya, especially the relevant unit (BSTI), include paying more attention to and improving IT services in the Tangibles and Reliability aspects, covering applications and facilities on campus, as they have a significant influence on user satisfaction.Therefore, the findings of this research can serve as a strategic foundation for the development of better, consistent, and responsive IT services to meet user expectations in the future.

FUTURE RESEARCH DIRECTIONS
Further research on the quality of IT services and user satisfaction at Unika Atma Jaya can consider several directions.Focus could be placed on the Assurance dimension, which indicates negative impacts, with in-depth research to understand the factors influencing user trust.Longitudinal studies could be conducted to monitor changes in user satisfaction over time.Additionally, comparisons with similar institutions, qualitative analysis of Responsiveness, and integration of service provider and IT staff perspectives could provide deeper insights.Exploring the impact of external factors, such as technology trends and social changes, as well as evaluating user technology adoption, could also be useful research focuses.Thus, this research is expected to make a valuable contribution to understanding the quality of IT services and user satisfaction at Unika Atma Jaya.
