The sample comprises the five-year budgetary framework of the Regional Revenue and Expenditure Budget (APBD) for Kediri Regency during the period from 2018 to 2022. The current phenomenon observed in the budget reports and realizations established within the framework of the Regional Revenue and Expenditure Budget (APBD) of Kediri Regency pertains to local taxes, regional levies, the management of separated regional wealth, and other legitimate sources of local revenue. Specifically, an analysis of the budget and realization from 2018 to 2022 reveals discrepancies in revenue generation year over year, alongside an examination of the growth rates and their contributions to overall revenue. These discrepancies serve as a basis for evaluating the effectiveness of the budget as set forth in the APBD of Kediri Regency. Consequently, it is imperative to conduct research focused on the effectiveness, growth rates, and contributions of these revenues to local income. A detailed examination of the budget and realization data from 2018 to 2022 indicates notable variations in revenue collection from year to year, as well as an analysis of the growth trends and their respective contributions to total revenue. These variations will inform the assessment of whether the budget, as established by the APBD of Kediri Regency, is effective or not. Therefore, it is essential to undertake research that investigates the effectiveness, growth rates, and contributions of these revenues to local income.
