This study analyzed the effectiveness and contribution of the Food and/or Beverage Tax, Hotel Services Tax, and Art and Entertainment Services Tax to Jakarta's Regional Own-Source Revenue during 2018–2024, and formulated policy recommendations based on fishbone (Ishikawa) analysis for the lowest-performing tax type. A descriptive quantitative approach supported by qualitative analysis was employed. Secondary data were obtained from Regional Government Financial Reports, while primary data were gathered through in-depth interviews with the Regional Revenue Agency, a tax consultant, an event organizer, and a venue operator. The Hotel Services Tax recorded the highest average effectiveness at 108.25%, followed by the Food and/or Beverage Tax at 100.72%, and the Art and Entertainment Services Tax at 98.88%. All three fell under the very low contribution category, with the Art and Entertainment Services Tax recording the lowest average at 1.16%. Fishbone analysis identified six root cause categories: disproportionate staffing and insufficient socialization (Man), reactive collection mechanisms (Method), limited tax technology implementation (Machine), misclassified business data and weak regulatory dissemination (Material), underreported revenues and high tax rates suppressing voluntary compliance (Measurement), and high entertainment sector elasticity with slow post-pandemic recovery (Environment). Policy recommendations were formulated across all six factors to optimize regional tax revenue.

This study aims to analyze the effect of Gross Regional Domestic Product (GRDP), Local Taxes, and Population on Local Own-Source Revenue (PAD) in 35 regencies/cities of Central Java Province during 2021–2023. The study employs a quantitative approach using secondary data obtained from the Central Java Statistics Agency (BPS) and Local Government Budget Realization Reports (LRA). The sample was selected using a census sampling technique and analyzed using multiple linear regression after classical assumption testing. The results indicate that GRDP and Local Taxes have a significant effect on PAD, while Population does not have a significant effect on PAD. These findings imply that local governments should prioritize regional economic growth and optimize local tax collection to strengthen fiscal capacity rather than relying solely on population growth. The novelty of this study lies in its integrated examination of GRDP, Local Taxes, and Population across all 35 regencies/cities in Central Java during the 2021–2023 period, providing updated empirical evidence to support regional fiscal policy and local revenue optimization.

This study aims to analyze the contribution of state and regional taxes to state revenue and regional fiscal independence in Indonesia. Taxes are the primary source of revenue used to finance governance and national and regional development. The study employed a qualitative descriptive method with a literature review approach and secondary data analysis derived from the State Budget (APBN) report, the Central Statistics Agency (BPS), and various scientific articles indexed by Sinta. The data were analyzed to identify the contribution of taxes to state revenue and the role of regional taxes in increasing Regional Original Income (PAD). The results show that tax revenue remains the largest source of state revenue, with dominant contributions coming from Income Tax (PPh) and Value Added Tax (PPN). Furthermore, regional taxes play a crucial role in enhancing regional fiscal capacity and supporting the implementation of regional autonomy. The effectiveness of tax management is influenced by the level of taxpayer compliance, the digitalization of tax administration, and the quality of government oversight. This study implies that optimizing the tax system through digital transformation and increasing public awareness can sustainably strengthen state and regional revenue.

This study aims to analyze the process and implications of changes in the General Budget Policy (KUA) and the Temporary Budget Priorities and Ceilings (PPAS) on the preparation of the Revised Regional Revenue and Expenditure Budget (APBD) for the Fiscal Year 2025 at the Regional Financial and Asset Management Agency (BPKAD) of Sikka Regency. The research employs a qualitative descriptive approach using secondary data in the form of planning and budgeting documents as well as internship activity results. The findings indicate that the preparation process of KUA–PPAS has been conducted in accordance with applicable regulations, starting from planning based on RPJMD and RKPD, formulation by the Regional Government Budget Team (TAPD), and discussions with the Regional House of Representatives (DPRD), supported by the SIPD system. Changes in KUA–PPAS are influenced by internal factors such as discrepancies in revenue and expenditure realization, program shifts, and the utilization of budget surplus (SiLPA), as well as external factors including central government policy changes, macroeconomic conditions, and emergency situations.

This study aims to analyze the implementation of Land and Building Tax (Pajak Bumi dan Bangunan or PBB) collection and its significant impact on local revenue generation. Land and building tax is a crucial component of local government revenue in Indonesia, especially following the implementation of regional autonomy and fiscal decentralization policies. Despite its critical role in funding local infrastructure and public services, the realization of PBB often falls short of its potential targets. This research utilizes a qualitative descriptive approach, employing secondary data collected from local revenue agencies and extensive literature reviews of previous academic publications. The objectives are to evaluate the effectiveness of current collection mechanisms, identify the primary obstacles hindering taxpayer compliance, and assess the overall contribution of PBB to regional financial independence. The findings reveal that while the administrative framework for PBB collection is generally well-established, practical implementation faces numerous challenges, including outdated land value assessments, low taxpayer awareness, suboptimal database management, and limited human resources within the tax apparatus. Furthermore, the study indicates that targeted digitalization of tax services and proactive public socialization campaigns can significantly enhance compliance rates. Practically, the results provide valuable recommendations for local policymakers to reform their tax collection strategies, optimize revenue streams, and ensure sustainable regional development.

This study aims to analyze the influence of Regional Original Revenue (PAD), General Allocation Fund (DAU), Special Allocation Fund (DAK), and Tax Revenue Sharing Fund (DBHP) on Regional Expenditure, as well as to analyze whether the flypaper effect phenomenon occurs in Regencies/Cities in Jambi Province during the 2017-2023 period. The data used in this study is panel data that combines time series data for 7 years and cross-section data from 11 Regencies/Cities in Jambi Province. The analysis method used is panel data regression with the selected model Fixed Effect Model (FEM). The results of the study show that simultaneously (F Test), the variables PAD, DAU, DAK, and DBHP have a significant effect on Regional Expenditure. Partially (t Test), PAD and DBHP do not have a positive and significant effect on Regional Expenditure, while DAU and DAK show a positive and significant effect on Regional Expenditure. This study also found a flypaper effect in regencies/cities in Jambi Province. This indicates that regional governments in Jambi Province tend to be more responsive in increasing regional spending using transfer funds from the central government rather than optimizing their own potential Regional Original Revenue (PAD).

Motor Vehicle Tax (PKB) is a key pillar of Regional Original Revenue (PAD) that supports development funding. However, seasonal fluctuations in payment realization create uncertainties in local budget planning. This study aims to address the limitations of the standard Random Forestalgorithm, which suffers from extreme prediction failures on time-series data due to its inability to capture temporal transitions between months. The proposed solution implements feature engineering using a Cyclical Encoding approach (Sine and Cosine transformations) and Lagged Variables. The dataset comprises historical records of motor vehicle tax potential and realization from January 2021 to November 2025. The baseline model evaluation without feature engineering yields highly inaccurate predictions with a Mean Absolute Percentage Error (MAPE) of 203.47% (accuracy of -103.47%). Conversely, after integrating Cyclical Encoding and Lagged Variables, the proposed model's performance improves drastically, achieving a MAPE of 14.40% (an accuracy rate of 85.60%), an MAE of 9,317 units, and an RMSE of 12,638 units. Feature Importance analysis confirms that the cyclically encoded month feature contributes the highest weight to the model's decisions with a score of 0.5031, followed by the potential feature at 0.1798. This study demonstrates that time-based feature engineering effectively optimizes Random Forestfor precise tax revenue forecasting.

Village governance plays an important role in supporting the effectiveness of development planning and improving community welfare. This study aims to analyze financial management governance and the process of preparing the Village Revenue and Expenditure Budget (APBKal) in Kalurahan Poncosari, Bantul Regency, for the 2025 fiscal year. This research employs a qualitative approach using a case study method, involving in-depth interviews with key informants and documentation analysis of relevant regulations and financial reports. The results show that financial management in Kalurahan Poncosari has been implemented systematically through the stages of planning, implementation, administration, reporting, and accountability in accordance with applicable regulations. The planning process is conducted in a participatory manner through tiered community deliberations, such as hamlet-level deliberations and village development planning deliberations, involving residents. In addition, the use of digital systems such as E-RAB and Siskeudes supports transparency and administrative order. However, challenges remain, including limited budget flexibility due to mandatory programs from central and regional governments, limited human resource capacity, and shifts in community participation patterns. In conclusion, the governance of APBKal in Kalurahan Poncosari demonstrates compliance and accountability; however, improvements in administrative capacity and fiscal flexibility are needed to better respond to community needs.

This research investigates the effect of the amount of MSMEs, the number of buildings, and GRDP on regional tax revenue in selected cities and regencies in South Sulawesi, driven by the inconsistency between the growth of economic potential and the realization of tax revenue, where increases in MSMEs, buildings, and GRDP are not always followed by higher tax receipts. The study aims to analyze the effect of these variables and identify the most significant factors contributing to regional fiscal capacity. A quantitative approach is employed using panel data that combine time series and cross-sectional data from 2015-2024, analyzed through panel data regression with model selection based on Chow, Hausman, and Lagrange Multiplier test. The results show that partially, MSMEs and the number of buildings do not have a significant effect on tax revenue, while GRDP has a positive significant impact; however, simultaneously, all variables significantly influence tax revenue, as indicated by a high Adjusted R-squared value. These findings suggest that economic growth, as proxied by GRDP, plays a more dominant role in increasing tax revenue compared to the mere increase in the number of MSMEs and buildings, implying that optimizing tax revenue requires not only expanding economic potential but also enhancing tax compliance, administrative efficiency, and the quality of economic growth.

This study aims to analyze the level of fiscal independence and dependence on central government transfers in the Ambon City Government during the 2019–2024 period. The research employs a descriptive quantitative approach using secondary data from the Budget Realization Reports (LRA). The analysis is conducted through the calculation of fiscal independence ratios, transfer dependency ratios, as well as trend and annual growth analysis. The results indicate that the level of fiscal independence in Ambon City remains low and fluctuates, with a relatively small contribution of Local Own-Source Revenue (PAD) to total revenue. In contrast, the level of dependence on central government transfers is high and relatively stable, indicating the dominance of transfer funds in the regional revenue structure. These findings suggest that the region’s fiscal capacity is still weak and fiscal independence has not been optimally achieved. Therefore, strategic efforts are needed to enhance local revenue and to allocate transfer funds toward productive expenditures in order to strengthen the regional fiscal structure.

Market levies are a regional taxation category that holds significant promise for increasing regional fiscal resources, complementing local tax revenues. The objectives of this study are; (1) Understanding the Communication Mechanism in the Implementation of Market Service Fee Policy in Gorontalo City. (2) Examination of Resource Availability in the Implementation of Market Service Tax Policy in Gorontalo. (3) Understanding the Bureaucratic Framework in the Implementation of Market Service Tax Policy in Gorontalo City. (4) Examination of the Implementation of Market Service Tax Policy Disposition in Gorontalo City. The method used in this study is a descriptive qualitative method. The results of this study indicate that the communication of market service fee policy has been carried out through systematic formal channels and is supported by a clear bureaucratic structure and division of tasks, but its implementation is still not optimal. This is caused by several obstacles, including unequal understanding and distribution of information among traders, limited resources in terms of both quantity and quality of human resources, budget, and inadequate market facilities. Furthermore, weak coordination and suboptimal implementation of SOPs in the field also impact work consistency, while the disposition or attitude of implementers who have demonstrated commitment but are not yet unified requires a more comprehensive strategic approach. Therefore, integrated efforts are needed, including improving the communication framework, strengthening human resource capacity, improving facilities, stricter supervision, and ongoing coaching to create more effective and professional policy implementation.

This study aims to analyze the influence of Regional Original Revenue (PAD), General Allocation Fund (DAU), and Special Allocation Fund (DAK) on Capital Expenditure, with Budget Surplus (SiLPA) as a moderating variable in district and city governments across Banten Province for the 2020–2024 period. The background of this research is driven by the high regional dependence on central government transfer funds and the suboptimal allocation of capital expenditure as a key indicator of regional development. This study employs a quantitative approach using secondary data from Local Government Budget Realization Reports (LRA), analyzed through Multiple Linear Regression and Moderated Regression Analysis (MRA) using statistical software. The results demonstrate that PAD has a significant positive effect on capital expenditure, whereas DAU and DAK do not show any significant influence. Furthermore, the interaction test reveals that SiLPA is unable to moderate the relationship between PAD, DAU, or DAK and capital expenditure. These findings indicate that regional fiscal independence, through the optimization of PAD, serves as the primary determinant for capital investment. The implications of this study suggest that local governments should further optimize local revenue potential to reduce dependency on transfer funds and improve budget management efficiency to support sustainable regional development.

This study aims to analyze the contribution and effectiveness of Local Tax and Local Retribution revenues to the Regional Original Revenue (PAD) of Bantul Regency during the 2021–2024 period. This research employs a quantitative descriptive approach using secondary data obtained from the Budget Realization Report (LRA) of Bantul Regency. The data analysis techniques used include contribution ratio analysis and effectiveness analysis by comparing realization with predetermined targets. The results show that the contribution of Local Taxes to the PAD of Bantul Regency during the 2021–2024 period is classified as good, with an average of 45.12%. Meanwhile, the contribution of Local Retribution to PAD is categorized as very low, with an average of 6.37%. In terms of effectiveness, Local Tax revenue is considered very effective with an average effectiveness rate of 109.18%, while Local Retribution revenue is categorized as quite effective with an average effectiveness of 92.42%. Based on these results, it can be concluded that Local Taxes are the most dominant and reliable source of PAD in Bantul Regency, while Local Retribution, although quite effective in achieving its targets, still requires optimization. Therefore, efforts are needed to optimize the collection of local retributions through the expansion of retribution objects, the review of more realistic targets, and the improvement of regional revenue management quality.

This study aims to analyze the dynamics of development management in Tulang Bawang Regency, particularly in integrating policy, fiscal capacity, and public participation during the transition to the 2025–2029 Regional Medium-Term Development Plan (RPJMD). The study employed a descriptive qualitative method using data triangulation techniques derived from regional planning documents, financial statistical reports, and sectoral program evaluation results. The findings reveal that Tulang Bawang Regency has achieved significant progress in regional transformation and succeeded in reducing stunting rates through the Bergerak Melayani Warga (BMW) program. However, these achievements have not been supported by strong fiscal independence, while public participation remains largely dominated by a technocratic approach. The study highlights the urgent need for reforms in digitalization-based regional revenue management and stronger substantive community involvement to ensure that future regional development becomes more independent, participatory, sustainable, and inclusive in accordance with local community aspirations. These reforms are expected to strengthen governance effectiveness and improve equitable development outcomes across all regional sectors.

Parking tax collection as part of Specific Goods and Services Tax (PBJT) is an important source for increasing Local Own-Source Revenue (PAD). This policy is based on Law Number 1 of 2022 concerning Financial Relations between the Central Government and Regional Governments and is implemented through Regional Regulation of Bandar Lampung City Number 1 of 2024. This study aims to examine the implementation of parking tax collection as PBJT as well as the supporting and inhibiting factors in its execution. The research employs normative juridical and empirical juridical approaches with a descriptive qualitative method. Data were collected through documentation studies and interviews with the Regional Revenue Management Agency (BPPRD) of Bandar Lampung City as the implementing institution. The results show that the implementation of PBJT on parking services in Bandar Lampung City uses a self-assessment system, where parking operators calculate, collect, report, and remit taxes independently through e-SPTPD and SIMANTAP managed by BPPRD. Supporting factors include clear regulations, the utilization of information technology, growth in the parking sector, and inter-agency support. Meanwhile, inhibiting factors include suboptimal taxpayer compliance, limited human resources within BPPRD, technical issues in the reporting system, and fluctuations in revenue due to seasonal factors. Overall, the implementation of PBJT on parking services has been effective but still requires improved supervision to optimize regional tax revenue.

This study is motivated by the importance of economic growth as a key indicator of regional development performance and public welfare improvement. Economic growth reflects the ability of local governments to manage resources and implement effective fiscal policies. This research aims to analyze the development and the influence of Local Own-Source Revenue, General Allocation Fund, and Special Allocation Fund on the economic growth of regencies/cities in Jambi Province during the period 2020–2024. The study employs a quantitative approach combined with descriptive analysis. Secondary data are obtained from official publications of relevant institutions and analyzed using panel data regression with the Common Effect Model approach. The results indicate that Local Own-Source Revenue and the General Allocation Fund have a significant effect on economic growth, showing that the increase in regional revenue and fiscal transfers contributes to economic performance. Meanwhile, the Special Allocation Fund does not have a significant effect, indicating that its allocation may not be optimally utilized in stimulating regional economic activities. These findings imply that strengthening regional fiscal capacity and improving the effectiveness of fund allocation are essential to promote sustainable economic growth. The study also highlights the need for better policy coordination and efficient financial management at the regional level to reduce disparities and enhance development outcomes.  

This study aims to analyze the contribution of Regional Original Revenue (PAD) sources, the growth of PAD, and the level of regional fiscal independence in Tanjung Jabung Barat Regency during the 2017–2024 period. The PAD sources examined include local taxes, regional retributions, returns from separated regional assets, and other legitimate PAD. The data used in this study are secondary data in the form of Budget Realization Reports (LRA) of Tanjung Jabung Barat Regency for the period 2017–2024, obtained from the Regional Revenue Agency (Bapenda) of Tanjung Jabung Barat and the Directorate General of Fiscal Balance. This research employs a quantitative descriptive approach. The analytical techniques used include contribution analysis of PAD sources (local taxes, regional retributions, returns from separated regional assets, and other legitimate PAD), PAD growth analysis, and fiscal independence ratio analysis. The results indicate that PAD is predominantly contributed by other legitimate PAD, accounting for 62.54% of total PAD, followed by local taxes contributing 26.06%, while regional retributions and returns from separated regional assets contribute relatively low proportions. The growth of PAD during the study period shows fluctuations influenced by economic conditions, including the impact of the COVID-19 pandemic. Furthermore, the level of fiscal independence in Tanjung Jabung Barat Regency is categorized as very low, as reflected in the high dependence on transfer funds from the central government and other governmental assistance.

This study aims to examine the level of regional financial independence and various financial ratios in assessing the performance of regency and city governments in the Special Region of Yogyakarta (DIY) for the 2019–2024 period. The method employed is a descriptive qualitative approach supported by quantitative data in the form of Budget Realization Reports (LRA). Performance measurement was conducted through several key indicators, including independence, effectiveness, efficiency, and growth ratios. The results indicate that the level of fiscal independence remains relatively low, characterized by a high dependency on transfer funds from the central government. On the other hand, the effectiveness ratio shows good achievement, as most regions were able to meet their revenue targets, particularly from Local Own-Source Revenue (PAD). However, the efficiency of expenditure management remains uneven across regions. Furthermore, the revenue growth ratio shows fluctuations influenced by economic conditions, including the impact of the pandemic. Overall, regional financial performance still needs to be improved, especially in strengthening fiscal independence and optimizing PAD potential.

This study aims to analyze the conformity between the Tax Object Sales Value (NJOP) and land market value and its implications for optimizing Local Own-Source Revenue (PAD) from the Rural and Urban Land and Building Tax (PBB-P2) sector in Oebobo District, Kupang City. The research employed a quantitative approach with descriptive and comparative methods. Data were obtained from the Kupang City Regional Revenue Agency (Bapenda), the Directorate General of Fiscal Balance (DJPK), land market surveys, and property transaction data. The analysis was conducted by comparing NJOP values with actual land market prices using conformity ratio analysis. The results indicate that the conformity level between NJOP and land market value in Oebobo District remains low, ranging from 7.97% to 12.06%. Oetete Village recorded the highest conformity level at 12.06%, while Kayu Putih Village showed the lowest at 7.97%. These findings demonstrate that the NJOP determined by the local government has not yet reflected the actual market value of land. Although the realization of PBB-P2 revenue during 2021–2025 showed relatively effective performance, the low NJOP has caused the tax base to remain below the actual economic value of land, thereby limiting the optimization of PAD. Therefore, periodic and market-based NJOP adjustments are necessary to improve fiscal fairness, strengthen the regional tax base, and increase local revenue from the PBB-P2 sector sustainably.

This study examines Egypt's security dilemma in the Bab el-Mandeb Strait in response to the escalation of Houthi attacks on global maritime trade routes. Since late 2023, Houthi attacks on commercial ships in the Red Sea have disrupted major sea trade lanes, posing a direct strategic threat to Egypt, which relies heavily on Suez Canal revenues as a primary source of national income. This research employs a qualitative approach with a descriptive-analytical method, using secondary data from academic journals, international policy reports, and credible news sources. The analysis is grounded in Security Dilemma theory and the concept of Maritime Security within the framework of International Relations. Findings show that Egypt faces a complex strategic dilemma: on one hand, it must safeguard its economic interests through stable Suez Canal operations; on the other, direct military intervention against the Houthis risks political backlash from Arab public opinion and entanglement in Yemen's civil war. Egypt's response has therefore been calibrated, prioritizing diplomatic channels and multilateral coalition participation over unilateral military action. This research contributes a novelty by specifically mapping Egypt's strategic constraints in the Red Sea as a middle power caught between great power competition and regional non-state actor threats.
