The National Health Insurance (JKN) program is a strategic initiative by the Indonesian government to ensure accessible and affordable healthcare for all citizens. Based on literature review and analysis of secondary data, the JKN program significantly contributes to reducing direct household health expenditures (Out-of-Pocket/OOP), particularly among low-income and vulnerable populations. However, several challenges remain, including additional outlays for uncovered services such as non-generic medications and inpatient class upgrades, as well as limitations in health infrastructure. Furthermore, the integration of digital technology through the JKN Mobile application demonstrates a high level of effectiveness in administrative efficiency and user participation. This platform has expanded healthcare accessibility and improved user satisfaction, although digital literacy and technological disparities persist. Hence, strengthening technology-based policies and conducting regular evaluations are essential for ensuring the sustainability and equity of the JKN program implementation.

This study aims to analyze the level of efficiency and effectiveness in managing tax revenues in Indonesia and its contribution to national economic development. Taxes are the primary source of state funding and play a crucial role in supporting development programs and welfare distribution. However, there remains a gap between tax potential and realization, indicating the need to evaluate the current tax administration system. This research adopts a descriptive quantitative approach using secondary data from DJP, BPS, and the Ministry of Finance covering the 2019–2023 period. The findings show that tax collection effectiveness has been relatively high in the last two years, as indicated by revenue realization exceeding targets. Nevertheless, efficiency remains low due to suboptimal digital systems and limitations in human resource capacity. Effectiveness is also strongly influenced by information technology and the performance of tax officials. The study concludes that tax reform focused on digitalization and transparency must be strengthened to support sustainable economic development. These findings have important implications for future fiscal policies and suggest opportunities for further research using mixed-method approaches.

This study aims to analyze the financial relationship between the central and regional governments within the framework of fiscal decentralization and its impact on regional economic growth. The main focus is to evaluate the contribution of the General Allocation Fund (DAU) and the Special Allocation Fund (DAK) to Regional Original Revenue (PAD) and the equitable development between regions. Using a quantitative approach, the data was analyzed to assess how fiscal transfer policies support regional financial independence and sustainable development. The findings indicate that DAU and DAK significantly influence PAD growth; however, regional dependency on central government funds remains high. Furthermore, disparities in development between advanced and underdeveloped regions remain a significant challenge. This study recommends optimizing PAD management and implementing more equitable fiscal policies to support balanced development and inclusive economic growth in Indonesia.

This study aims to analyze the contribution of taxes and levies in a country's economy, focusing on the case of Indonesia. Taxes and user charges are fiscal policy instruments that play an important role in collecting government revenue to finance various development activities and public services. However, there are still various challenges in optimizing the contribution of these two instruments. The research method used is descriptive qualitative analysis, by conducting a literature review and case study of the tax and levy system in Indonesia. The results of the analysis show that taxes and user charges contribute significantly to the Indonesian economy, but there are problems such as low public tax awareness, potential tax leakage, and lack of transparency in the management of local user charges.
