Indonesia ARTICLE INFO Article history: Received 05 April 2025 Revised 26 May 2025 Accepted 17 June 2025 Keywords Corresponding Author : ABSTRACT This research examines how Mobile SAMSAT improves motor vehicle taxpayer compliance in Bandar Lampung City. Indonesia's growing fiscal demands for national expenditure and growth make regional taxes, especially motor vehicle tax, vital to local government revenue and public welfare. Motor vehicle tax contributes significantly to regional revenue, however taxpayer unfamiliarity with payment options and perceived burdensome SAMSAT office processes reduce In 2012. Bandar Lampung launched Mobile SAMSAT to provide door-to-door tax payment services, including annual Vehicle Registration Certificate (STNK) validation. Motor Vehicle Tax (PKB) payments, and Mandatory Road Traffic Accident Fund Contributions. This mixed-methods study used a Concurrent Triangulation Strategy to collect quantitative data from surveys and qualitative data from interviews and direct observation to evaluate program success factors. The results show that Mobile SAMSAT services promote taxpayer compliance via accessibility, clarity, and speed, boosting public trust and civic involvement in tax affairs. This efficacy is due to personnel response, appropriate service locations, and efficient administrative Mobile SAMSAT. Taxpayer Compliance. Motor Vehicle Tax. Public Service.

INTRODUCTION Increasing fiscal needs for national spending and development finance demand increased domestic income generation to reduce foreign funding The 1945 Constitution's Preamble encourages the Indonesian government to undertake comprehensive policies to create a fair and prosperous society. Therefore, federal and regional governments have made steps to increase state income collection (Maulana & Septiani, 2. According to the Regional Government Law, regional taxation is a key income source for local governments and may be adapted to regional needs. Regional taxes, like International Journal of Education. Social Studies. And Management (IJESSM) Volume 5. Issue 2. June 2025 Page 1041-1056 central taxation, boost local government earnings and promote public infrastructure and spending (Resmi, 2. The Regional Revenue and Expenditure Budget (APBD) shows how taxes may fund development. Indonesian Law No. 17 of 2003 describes APBD as Regional Representative Council-approved regional governments' yearly budgetary plan. A region's economic development trajectory predicts APBD size since it boosts revenues and social welfare. Regional Original Revenue (PAD) from taxes should rise proportionately with economic growth. Citizens' tax paying capacity should rise with economic growth. Enhancing taxpayer tax payment compliance is necessary to guarantee regional tax revenues successfully improve societal welfare via development programs and public services via APBD budget allocation. First-level regional taxes are regulated by provinces, whereas regencies or cities administer regional taxes (Siahaan, 2. Motor vehicle, transfer, gasoline, surface water, and cigarette taxes are controlled by provincial governments under Article 2 of Law No. 28 of 2009 on Regional Taxes and Levies. Lampung Province's 2023 tax collection statistics shows considerable differences per tax category. Despite placing second in percentage terms, motor vehicle tax had the greatest nominal realisation at 1,028,551 billion rupiah, 49% of the objective. This makes motor vehicle tax the largest tax category Only 660,934 billion rupiahAi88. 12% of the 750 billion targetAiwas raised for motor vehicle transfer tax. Motor vehicle fuel tax reached 104. 46% of the 840 billion rupiah goal with 877,494 billion. In monetary terms, surface water use tax contributed the least, yet it achieved 9,477 billion rupiah, 135. of the 7 billion objective. Cigarette tax income fell to 656,366 billion rupiah, 08% of the 736,838 billion goal. Despite placing second in percentage accomplishment at 105. 49%, motor vehicle tax is the greatest regional tax income source at 1,028,551 billion rupiah. Whether meeting or missing expectations, motor vehicle tax is the biggest Motor vehicle tax may boost regional income, according to Widyaningsih . Ramdani et al. ascribe this to Indonesia's rapidly growing motor vehicle population. The tendency towards providing everyday living requirements via increased community mobility promotes this rise. Annual population growth increases motor vehicle use. Thus, local governments' best income source is taxes. Increased car populations may not always lead to taxpayer compliance, with people still avoiding taxes. As the province's economic and transportation centre. Bandar Lampung City has the most motor vehicles . ,035,. Central. South, and East Lampung also have large motor vehicle populations: 654,100, 540,230, and 418,485 International Journal of Education. Social Studies. And Management (IJESSM) Volume 5. Issue 2. June 2025 Page 1041-1056 These regions have large populations and are agricultural and transportation hubs, resulting in high motor vehicle ownership. Mesuji Regency has 54,464 motor vehicles, the lowest in Lampung due to its rural nature and little urbanisation. The majority of vehicles in Bandar Lampung are motorbikes . Trucks total 67,281 units, while passenger cars total 154,315. Bus numbers remain low at 2,721 units. This data supports focussing on motorbikes for this study since they are the most common motor vehicle in the city. Bapenda's Joint Office of the One-Stop Integrated Administrative System (SAMSAT) processes Motor Vehicle Tax (PKB) and Motor Vehicle Transfer Tax (BBNKB) payments. SAMSAT symbolises public confidence in PKB and BBNKB payment systems since people pay taxes on new and used car transactions. SAMSAT has supervisors, coordinators, and implementers who serve people during tax payments as a joint office. Rajif . suggests that great service and benefit explanations might boost taxpayer compliance. Public Service Accountability is a new paradigm that addresses perceptions of citizen-desired and government-provided services. Public service transparency affects income sources (Yadnyana & Sudiksa, 2. Low taxpayer compliance is due to taxpayer ignorance about taxes as development support, according to Aryatika & Mildawati . Thus, people fail to realise that delayed tax payments harm public service development, facilities, and other tax-funded activities. Understanding tax advantages and relevance helps raise taxpayer awareness. Citizens cannot happily pay taxes without tax and benefit understanding (Rabiyah et al. , 2. From observation, many taxpayers at the SAMSAT Joint Office in Bandar Lampung are inexperienced with tax payment methods. SAMSAT Office tax payments are also seen as cumbersome, making taxpayers hesitant to self-pay. Therefore, many taxpayers use intermediate services to pay taxes, which may be Maulana & Septiani . say government or SAMSAT office service quality affects taxpayer tax compliance. All SAMSAT Joint Office of Bandar Lampung City components work to maximise tax services and income. Presidential Regulation No. 5 of 2015 Chapter V Implementation Article 22 establishes auxiliary units like Helper SAMSAT. SAMSAT Outlets. DriveThrough SAMSAT. Mobile SAMSAT. Drive Order SAMSAT. E-SAMSAT, and others to improve SAMSAT Joint Office service quality in line with technological advances and public expectations. The Mobile SAMSAT initiative provides door-to-door tax payment options in Bandar Lampung City to vehicle owners/taxpayers far from central SAMSAT facilities to improve taxpayer Mobile SAMSAT covers vehicle owners/taxpayers far from central International Journal of Education. Social Studies. And Management (IJESSM) Volume 5. Issue 2. June 2025 Page 1041-1056 SAMSAT services with annual Vehicle Registration Certificate (STNK) validation. Motor Vehicle Tax (PKB) payments, and Mandatory Road Traffic Accident Fund Contributions (SWDKLLJ) door-to-door. This program to enhance public service quality, notably Motor Vehicle Tax payment services, benefits residents by enabling yearly STNK validation. PKB and SWDKLLJ payments, and bringing services closer to Bandar Lampung communities while decreasing expenses. Purnaman et al. found that Mobile SAMSAT installation boosts taxpayer compliance. Officials' convenience, speed, accuracy, and service ease, including Mobile SAMSAT services, make citizens more compliant with PKB payments. Mobile SAMSAT services solve issues caused by citizen dwellings far from SAMSAT offices and office placements on Bandar Lampung city peripheries, which discourage tax Although SAMSAT offices make tax payment easy. Mobile SAMSAT is more efficient owing to its simple payment methods and low prerequisites, such as STNK and ID card photocopies. Government mobile SAMSAT services at Bandar Lampung SAMSAT Office help citizens pay motor vehicle taxes. Mobile SAMSAT tax payments cannot be outsourced, preventing middlemen. Mobile SAMSAT's efficacy in improving motor vehicle taxpayer compliance in Bandar Lampung City is the focus of this study. The study tackles two main research questions: what factors affect Mobile SAMSAT program success in improving taxpayer compliance, and if Bandar Lampung City Mobile SAMSAT programs promote taxpayer compliance. Research significance includes academic contribution through additional information and references for future research while improving student insights into tax governmental utility as policy consideration for motor vehicle tax compliance enhancement with Regional Original Revenue improvement and researcher benefits through expanding taxation knowledge and implementing academic knowledge to understand actual field conditions. RESEARCH METHOD Type of Research This mixed method research (MMR) study uses the Concurrent Triangulation Strategy model to gather and integrate quantitative and qualitative data to improve research depth and validity (Creswell & Plano Clark, 2. The data will be collected using surveys. The main goal is to study how mobile SAMSAT services improve motor vehicle taxpayer compliance in Bandar Lampung City. The research will also examine other variables impacting taxpayer compliance and how mobile SAMSAT services might simplify tax payment. International Journal of Education. Social Studies. And Management (IJESSM) Volume 5. Issue 2. June 2025 Page 1041-1056 Type and Source of Data and Data Collection Method This research uses primary and secondary data. The researcher interviews Bandar Lampung City motor vehicle taxpayers to gain first-hand data on the study topic (Sugiyono, 2. Secondary data are obtained indirectly from Lampung Province's Regional Revenue Agency (BAPENDA) records (Sugiyono, 2. Data is collected using a Likert scale and direct observation. Structured surveys use the Likert scale to evaluate respondents' perceptions, attitudes, and opinions for quantitative and qualitative analysis. This method helps understand respondent agreement with study variable statements (Likert. Allen & Seaman, 2. Field circumstances are also recorded using observational methods to track mobile SAMSAT officials and taxpayers during mobile tax services in Bandar Lampung City. Data Validity Research results must be accurate and credible via data validity. Inaccurate data may lead to incorrect conclusions, yet good data support reasonable interpretations. Positivist data validity adapts validity and reliability to methodological criteria. Instrument validity is determined by how effectively the questionnaire measures the target variable. This is done using Pearson correlation between item scores and overall variable scores. A questionnaire is legitimate if the significance value is below 5% and the correlation coefficient surpasses the threshold r-table value (Nunnally & Bernstein, 1. The dependability coefficient. Cronbach's Alpha, runs from 0 to 1. Reliable instruments have alpha values over 0. 6, suggesting consistent measurement (Sugiyono, 2. Reliable equipment promote constant data collection, boosting measurement confidence and study data quality. Data Questionnare The seven indicatorsAitimeliness, responsiveness, communication, location, information, administrative processes, and service qualityAiwere utilized to evaluate taxpayers' satisfaction with the tax office's services adopted from Montayo & Sayson . Timeliness assessed how promptly staff provided necessary information and responded to inquiries, reflecting efficiency in service delivery. Responsiveness measured the willingness of tax officers to address concerns and resolve issues quickly, fostering trust and Communication evaluated the clarity and effectiveness of information exchange between staff and taxpayers, ensuring understanding of procedures and policies. The location indicator considered the convenience and accessibility of the tax office, impacting ease of physical access for taxpayers. Availability and clarity of tax-related information ensured taxpayers could easily find and comprehend relevant guidelines, forms, and procedures. International Journal of Education. Social Studies. And Management (IJESSM) Volume 5. Issue 2. June 2025 Page 1041-1056 Administrative processes examined the simplicity, fairness, and efficiency of tax assessment and payment procedures, influencing overall satisfaction. Lastly, service quality assessed staff professionalism, courtesy, and helpfulness, which formed the basis for positive perceptions and willingness to comply voluntarily Mixed Method Research Mixed Method Research (MMR) uses philosophical assumptions to guide It combines qualitative and quantitative methods during data collection, analysis, and interpretation to better comprehend the study topic (Creswell & Plano Clark, 2. MMR is used to study research topics from numerous viewpoints, which provides deeper understanding, richer context, validation of results, and a more complete investigation of social phenomena (Axinn & Pearce, 2. Concurrent embedded, sequential exploratory, concurrent transformational, concurrent triangulation, sequential explanatory, and sequential transformative MMR techniques exist (Creswell & Plano Clark. Martono . lists four critical MMR dimensions: timing . cheduling qualitative and quantitative data collection sequentially or simultaneousl. , weighting . rioritising one method over the other based on research objective. , mixing . ntegrating data during collection, analysis, and interpretatio. , and theory development. This research collects qualitative and quantitative data concurrently via The two datasets are compared to see whether they match, vary, or complement. Integrating both data types validates results and provides deeper insights, helping the researcher grasp the study topic better (Martono. Triangulation improves data validity, reliability, depth, and impartiality, making it helpful for evidence-based decision-making, according to Dawadi et . Statistics are used to analyse quantitative data, whereas qualitative analysis is used for qualitative data. A complete synthesis of various analytical methods enhances study findings (Creswell & Plano Clark, 2.

SAMSAT Drive-Thru in Rajabasa and Gunung Sugih lets taxpayers make transactions from their cars. E-Salam (Electronic SAMSAT Lampun. , a smartphone app for timely payments, and E-Samdes, a village-owned business tax service, are digital advancements. The central SAMSAT Induk offices in Bandar Lampung and Gunung Sugih provide registration, identification, and car tax payment. Bapenda's diversified initiatives improve tax compliance and public administration equality, efficiency, and service innovation. Profile of Mobile SAMSAT of Bandar Lampung City Mobile SAMSAT services improve car tax payment accessibility and efficiency via public administration innovation. This service delivers tax services directly to communities using operable vehicles like busses or vans for people who are time-constrained or far from central SAMSAT offices. Mobile SAMSAT, launched in 2012 in Bandar Lampung, shows the local government's dedication to public service and tax compliance. By providing services in hightraffic public spaces, the program minimizes administrative and logistical hurdles that delay or skip payments. The goal is to make tax payments easier and emphasize their relevance. Mobile SAMSAT in Bandar Lampung rotates schedules and locations to enhance outreach. The first zone contains Sukarame and the PKOR Way Halim International Journal of Education. Social Studies. And Management (IJESSM) Volume 5. Issue 2. June 2025 Page 1041-1056 sports and cultural complex, selected for their high population density and public activities. The second zone includes Pahoman and Teluk Betung, important government, educational, economic, and recreational sites. This segmentation provides equitable service delivery in urban and semi-urban Mobile units with computerized administrative systems and skilled workers provide safe, efficient transactions. In addition to processing payments, the units offer tax-related information and consultations, raising taxpayer knowledge and accountability via human-centered and proactive public service Respondent Characteristics Based on the data collected, the majority of respondents were male, totaling 37 individuals or 53%, while female respondents accounted for 33 individuals or 47%. In terms of age distribution, the largest proportion of respondents fell within the 20Ae30 years age group, comprising 60 individuals or 86% of the sample. Meanwhile, respondents aged 31Ae40 years represented 10% . , and those in the 41Ae50 years age group accounted for the remaining 4% . These demographic characteristics suggest that the sample is predominantly composed of young adult males. Data Quality Assesment Research data validity is essential to discovering accuracy and reliability. Valid data supports appropriate interpretations, whereas invalid data may lead to incorrect conclusions. Data validity in the positivist paradigm develops from validity and reliability to methodological norms and research settings. Validity testing determines how well the questionnaire measures the desired constructs. This procedure compares item scores to variable totals. If the significance value is below 0. 05 and the estimated correlation coefficient . -coun. surpasses the necessary r-table value, the item is legitimate. All indicators of the seven variablesAitimeliness, responsiveness, communication, location, information, administrative processes, and service qualityAihad r-count values over 0. and p-values below 0. Therefore, all indicators are genuine, indicating the accuracy and suitability of the instrument employed to gather data from 70 Table 1.

Instrument reliability refers to its stability and dependability in producing consistent findings under identical settings. This research assessed variable reliability using Cronbach's Alpha. The instrument is dependable if Cronbach's Alpha is above 0. Sugiyono . states that the instrument's consistency in assessing the same construct across several applications increases as the coefficient approaches 1. Table 2 shows that all variables have Cronbach's Alpha values over 0. 60, from 0. 609 to 0. Thus, the variables are dependable since the questionnaire questions consistently reflect the examined constructs. The validity and reliability tests show that this research's instrument passes academic psychometric standards. Timeliness, responsiveness, communication, location, information, administrative methods, and service quality were all measured validly and reliably. This boosts data trustworthiness and supports statistical analysis. The interpretability and generalizability of behavioral and social sciences research results depend on accurate and trustworthy instruments. Table 2.

These aspects enhance customer service and encourage tax compliance. The mobile service's direct contact with taxpayers has created a more human-centered approach that simplifies compliance, lowers middlemen, and raises tax knowledge. Courteous officers, honest communication, and reduced bureaucratic processes have increased public confidence and civic involvement in tax concerns. Several suggestions are made to enhance mobile SAMSAT services. First, police must improve their interpersonal communication skills to help raise tax awareness via persuasive and instructive contacts. Second, extending coverage especially to highly populated or low-compliance regionsAiwould improve service fairness and accessibility. Third, improving supporting amenities like seats, electronic queuing, and digital information transmission via social media or mobile apps will boost convenience and efficiency. Officers must also get continuing customer service and digital literacy training to improve service and taxpayer satisfaction. Finally, frequent review with community input is needed to enhance services to meet public expectations and changing urban needs in Bandar Lampung. International Journal of Education. Social Studies.
