INTRODUCTION The provision of public services by government officials to the people is actually an implication of the function of state officials as public servants. The results of a survey by the Ministry of Empowerment of State Apparatus showed that the level of public satisfaction from local governments, ministries, and institutions in Indonesia was 3. 63, which means that the public is satisfied with public services in Indonesia (Menpan 2. This level of satisfaction cannot be separated from the increasingly critical conditions of society, the public bureaucracy is required to be able to change its position and role in providing public services. From those who like to regulate and command, changing to liking to serve, from those who like to use a power approach changing to liking to help without Public service can be interpreted as providing services . the needs of a person or community who has an interest in the organization in accordance with the basic rules and procedures that have been established. This provides an understanding that everything related to service must be carried out as well as possible so that the community who receives the service feels satisfied with the service provided. (Siregar, 2. A 2025 ADPEBI Publications. All Rights Reserved. International Journal of Law Policy and Governance Vol. 4 No. 1, 2025 Public service is an effort by the government to meet the needs of the community. The services provided to the community must always be good and of a quality that is close to the expectations of the community because the good and bad public services provided by bureaucrats to the community are often used as a benchmark for the success of a government agency. (Amhas, 2. Fulfillment of needs and desires as well as the value of service quality/service is very much determined by customer satisfaction, one of which is Taxpayers. Unsatisfactory service will result in a reduction in Taxpayers or even their disappearance. This is a major challenge for the tax office in building a corporate image and providing satisfactory service. Strict competence presents various ways to meet service satisfaction, namely by implementing innovations in the services offered and paying attention to the quality of service that is expected to foster service satisfaction(Yordan Antanegoro. Surya and Sanusi, 2. Service satisfaction is a form of feeling that arises because what is expected by Taxpayers is felt in a service which can then increase or decrease Taxpayer compliance. This service satisfaction can be formed through service quality which can be in the form of service quality that is assessed visually by consumers . , it can also be in the form of service success according to needs. Taxpayer, functions, and values expected byTaxpayer. , employee alertness in providing services . , the existence of a guarantee that the information provided during the service is correct . , and the desire to help that arises whenTaxpayerfeel difficulties both in deciding to pay taxes in other matters concerning services . The quality of this service can have an impact on feelings of comfort, security, and desireTaxpayerto continue to comply with paying Taxpayers, where this quality must also be balanced with service innovations that are in accordance with current (Fauzi and Mandala, 2. KPP Pratama Kebayoran Baru Satu is located in the South Jakarta area, which is one of the Tax Service Offices under the South Jakarta II Regional Office of the Directorate General of Taxes. task is to collect state revenue, receive tax reports, consult in the field of taxation and education of Taxpayers (WP). Tax services inThe First Tax Office of Kebayoran Baru Onecomputer-based . and applications. The service has a section that handles direct services to taxpayers, namely the service section consisting of frontliners called TPT (Integrated Service Plac. and there is a helpdesk tasked with assisting taxpayers who ask questions about taxation. In addition, there is a supervision section . as sectio. , there are tax employees who serve as AR (Account Representativ. whose duties are to supervise tax reporting and payments, education, and consultation in the field of taxation for registered taxpayers. This AR is the liaison between taxpayers and the Tax Service Office (KPP) for services and supervision in their tax obligations. The Directorate General of Taxes has a complaint facility to accommodate questions, complaints, suggestions, input and criticism. For the public sector, the great responsibility of bureaucracy in providing services to the community must be supported by professional and competent Human Resources (HR) of the apparatus. In the context of bureaucratic reform. HR Improvement is one of the pillars of improvement in addition to institutional and system Improvement of human resources is part of the modernization of the tax administration system that must be carried out by the Directorate General of Taxes. If the improvement of Human Resources is the main key to the success of reform, wherever the most important element in an organization lies in its human resources. No matter how sophisticated or great an organization is, if it is not supported by qualified and highly integrated human resources, the organization will slowly collapse and the goals of the organization will not be achieved.

The influence of service innovation on service quality. The implementation of service innovation used by the Surabaya II Land Office is a process of improving the service system against the general service standards at the All Indonesia Land Office that already existed previously. The service innovation carried out by the Surabaya II Land Office has also been in accordance with the innovation attributes put forward by Rogers but still requires continuous The quality of service at the Surabaya II Land Office is considered quite good, although it still needs improvement in physical facilities and Human Resource development.

The correlation between knowledge donation has a positive and significant effect on service innovation, and a positive and significant effect on department performance. The correlation between knowledge collection has a positive and significant effect on service innovation but does not have a significant effect on department performance. Service innovation does not mediate the correlation between knowledge donation and department performance, but mediates knowledge collection and department (Wahyuni & Kistiyanto, 2. There is a simultaneous positive and significant influence of service quality and service innovation on consumer satisfaction. (Muslichati & Wartini, 2. From the governance and innovation indicators, the regulatory system used is in accordance with the Drive Thru service. The source of innovation ideas is obtained from the internal leadership of the organization.

The influence of administrative systems on service satisfaction. The results of the study indicate that the modernization of the tax administration system and the competence of tax employees simultaneously have a significant effect on taxpayer satisfaction. Some of the results of the sampling test of the modernization of the tax administration system and the competence of tax employees have a significant effect on taxpayer satisfaction. The results of this study suggest that what must be done by employees and all parties related to the Tax Service Office is to pay attention to the factors of the modern tax administration system and the competence of tax employees. Quality service from tax employees can make taxes feel comfortable and comfortable satisfied in fulfilling their obligations to pay taxes(Rembet et al. , 2. There are also those who state that the quality of the information administration system has a significant influence on user (Panjaitan et al. , 2.

Evaluation of Measurement Model or Outer Model Evaluate the measurement model or external model to explain how each indicator relates to the latent variable. This external model evaluation is a validity and reliability test. Reliability testing is carried out to ensure that each question item in the questionnaire is valid or not, while reliability testing is carried out to ensure that the questions in the questionnaire are valid, reliable and consistent in measuring the same symptoms in all respondents. In SEM-PLS, the tests carried out Convergent Validity Convergent validityis the first test conducted to determine the validity of each relationship between indicators and constructs or other variables. The Measurement Model with indicator reflection in PLS calculates the correlation between component scores . tem scor. withconstruct score. The size of individual reflection is said to be high if it has a correlation exceeding 0. 50 of the variables or constructs to be measured. , as stated in the following table: Variables Service Satisfaction Quality of Service Administration System Service Innovation Quality of Human Resources Table 4. 5 Convergent Validity Test Results Indicator 18.

Analysis of Service Quality on Tax Service Satisfaction Based on the results of the convergent validity test, it shows that all variables have a value >0. This means that the sizeindividual reflectivity is considered high if it correlates more than 0. with the measured construct. (Ghozali, 2. Discriminant Validity The next criterion for evaluating the outer model is discriminant validity, which is to ensure that each concept of each latent model is different from other variables. One way to measure the outer model with discriminant validity is based on the cross loading value of the construct correlation with its measurement items. Table 4. 6 Cross Loading Test Results Quality Quality of Cross Administration Service Service Human Loading System Innovation Satisfaction Service Resources X1. X1. X1. X2. X2. X2. X2. X3. X3. X3. From the cross-loading results, it shows that the correlation value of the construct with its indicators is greater than the correlation value with other program constructs. Thus, all constructs or latent variables have good discriminant validity, the indicators in the construct indicator block are better than the indicators in other blocks. Another way to test discriminant validity through SmartPLS besides the cross loading value is by using the Average Variance Extracted (AVE) method on each construct or latent variable shown in the table below: Table 4. 7 Test ResultsAverage Variance Extracted(AVE) A 2025 ADPEBI Publications. All Rights Reserved. International Journal of Law Policy and Governance Variables Service Satisfaction Quality of Service Administration System Service Innovation Quality of Human Resources Vol. 4 No. 1, 2025 Average variance extracted (AVE) The results show that the AVE value is greater than 0. 50, with the smallest value being 0. for the variableQuality of Serviceand the largest is 0. 669 for the variableAdministration System and Service Innovation. The value meets the requirements according to the minimum limit of the specified AVE value, which is 0. 50, meaning that the model has quite good discriminant validity because the AVE value of each construct is greater than 0. Composite Reliability & Cronbach Alpha The next test in the Measurement Model or outer model is construct reliability, which is to prove the accuracy and consistency of a construct. The measurement method is carried out in two ways, namely with composite reliability and Cronbach Alpha which are shown in Table 4. Table 4. 8 Results of Composite Reliability and Cronbach Alpha Tests Variables Service Satisfaction Quality of Service Administration System Service Innovation Quality of Human Resources Composite reliability Cronbach's alpha From the results uji Composite Reliability valueand Cronbach Alpha in Table4. 8 shows a composite reliability value > 0. 70and Cronbach Alpha > 0. 60for all constructs. With the resulting values, all constructs have good reliability according to the minimum value limits that have been required, so that kthe construct is declared reliable(Ghozali, 2. Structural Model or Inner Model Evaluation Structural model testing or inner model is to evaluate the relationship between latent constructs as hypothesized in this study. The methods used include: R-Square R squared is a measure of the proportion of variation in the value of an affected variable . that can be explained by the variables that influence it . The higher the Rsquared value, the better the degree of determination, the following results are obtained: Table 4. 9 R-Square Test Results Average RVariables R-Square Square Service Satisfaction Quality of Service A 2025 ADPEBI Publications. All Rights Reserved. Analysis of Service Quality on Tax Service Satisfaction Based on the R-squared value, it can be seen that service satisfaction has an R-squared value 700 and service quality has an R-squared value of 0. 716, meaning that both variables have a similar model. They have an r-squared value > 0. (Ghozali, 2. The R-square value of the job satisfaction variable is0. 700This means that leadership style and organizational culture are able to explain 70. 0% of the service satisfaction variance, the rest is influenced by other factors. Likewise, the R-square value for the service quality variable 716which means that leadership style and organizational culture through job satisfaction can 6% of the variance in service quality, while the rest is influenced by other factors. Goodness of Fit(GoF) through Q-Square analysis In structural models. Q-Square predictive relevance is used to measure how well the observed values produced by the model and also its parameter estimates are. (Ghozali, 2. To calculate QSquare, you can use the Stone-Geisser Q-Square Test formula: Q2 = 1 Ae . -R. -R. Q2 = 1 Ae . Q2 = 1 Ae 0. Q2 = 0. The Q2 value of 0. 416 or 41. 6% . reater than zer. indicates that the model in this study is quite good, so that the predictions made by the model are relevant, namely that the model used is able to explain the information contained in the research data by 41. Furthermore, by using the SmartPLS application to determine the Q2 value, the following results were obtained: Table 4. 10 Communality Test Results Variables Communal Average Communality Service Satisfaction Quality of Service Administration System Service Innovation Quality of Human Resources Based on the test resultscommunalityand R-Square, to test the goodness of fit of the model using the GoF formula calculated from the square root of the average communality index and average R-Square values. =Ooaverage comm index x average R2 =Oo0. 375 x 0. =Oo0. = 0. obtained a value of 0,515including large GoF levels,This means that the measurement model . uter mode. and the structural model . nner mode. are appropriate or valid. F-Square F-squareis a measure used to assess the relative impact of an influencing variable . on the influenced variable . Based on the calculation results in Smart PLS, it can be stated as follows: Table 4. 11 f-Square Test Results Influence Administration SystemIeQuality of Service Service InnovationIeQuality of Service A 2025 ADPEBI Publications. All Rights Reserved. f-Square Information International Journal of Law Policy and Governance Quality of Human ResourcesIeQuality of Service Administration SystemIeService Satisfaction Service InnovationIeService Satisfaction Quality of Human ResourcesIeService Satisfaction Quality of ServiceIeService Satisfaction Vol. 4 No. 1, 2025 This f-square test is conducted to determine the goodness of the model. F-square values of 0. 15 and 0. 35 can be interpreted as whether the latent variable predictor has a weak, medium or large influence at the structural level. (Ghozali, 2. Based on the results of the f-square test, it shows that the variable of the administrative system on service quality has a value of 0. 249 and the variable of the administrative system on service satisfaction has a value of 0. 041, which means that the influence of the administrative system on service quality and service satisfaction is medium. The variable of service innovation on service quality has a value of 0. 021, which means that the influence of service innovation is weak, while the influence of service innovation on service satisfaction has a value of 0. 165, which means that service innovation has a medium influence on service satisfaction. The variable of human resource quality on service quality has a value of 0. 365, which means that human resource quality has a large influence on service quality, while human resource quality on service satisfaction has a value of 0. 010, which means that human resource quality has a weak influence on service satisfaction. The variable of service quality on service satisfaction has a value of 0. 126, which means that service quality has a weak influence on service (Ghozali, 2. Estimate For Path Coefficients Path analysis is carried out to see the significance of the influence between variables by looking at the parameter coefficient values and the t-statistic significance values, namely through the bootstrapping method.
