This investigation adopts a quantitative methodology utilizing secondary records in the form of Audit Reports on Local Government Financial Statements (LHP LKPD) and the BPK’s Semiannual Audit Summary (IHPS), obtained from the official website of the Supreme Audit Agency of the Republic of Indonesia (BPK RI), as well as the Evaluation Report on the Electronic-Based Government System (SPBE), sourced from the official web portal of the Ministry of Administrative and Bureaucratic Reform (KemenPAN-RB). The research demographic comprises of 38 provincial governments in Indonesia. This paper employed a purposive sampling method with a population of 34 provincial governments in Indonesia during the 2020–2024 period, resulting in 170 observations.
