This study aims to qualitatively analyze the coupon-setting strategy employed by the Directorate General of Budget Financing and Risk Management (DJPPR) in response to fluctuations in Bank Indonesia's benchmark interest rate, specifically the BI 7-Day Reverse Repo Rate (BI7DRR), during the 2021–2024 period. Using a descriptive-analytical approach based on a literature review, the research examines official policy documents, historical BI7DRR data, and relevant academic studies. The findings indicate that DJPPR implemented a floating with floor coupon mechanism as an adaptive strategy to address interest rate volatility. This mechanism has proven effective in maintaining the appeal of Savings Bond Ritel (SBR) among retail investors, while also reflecting the synergy between fiscal and monetary policy in managing national debt instruments

Mobile vehicle tax service is one of the regional government initiatives designed to facilitate tax compliance and increase regional revenue. This study aims to examine the contribution of mobile tax units in boosting local revenue in Sukabumi Regency. The methodology applied in this research is a descriptive qualitative approach, with data collection conducted through direct observation. The findings reveal that the implementation of mobile tax units produces significant effects on increasing the number of taxpayers, resulting in higher local revenue from the vehicle tax component.
