The tax ratio is a key fiscal performance indicator; however, Indonesia’s tax ratio remains relatively low compared to its economic potential and the regional average of Asia-Pacific countries.This study employs a quantitative approach using panel data comprising 34 provinces over 5 observation years (2020–2024), yielding a total of 170 observations. The analysis utilizes panel data regression with the Fixed Effect Model (FEM), selected based on the results of the Chow Test and Hausman Test. Data were obtained from the Central Bureau of Statistics (BPS), the Ministry of Finance, and the Corruption Eradication Commission (KPK).The results indicate that, partially, the unemployment rate has a significant negative effect on the tax ratio, meaning that higher unemployment leads to lower tax revenue. Meanwhile, IPAK and GRDP per capita have a positive but insignificant effect on the tax ratio, while HDI has a negative but insignificant effect. Simultaneously, all four variables jointly exert a significant influence on the tax ratio in Indonesia. An Adjusted R-Squared value of 0.7313 indicates that 73.13% of the variation in the tax ratio is explained by the four variables in the model.This study recommends that the government focus on creating quality employment in the formal sector, improving the effectiveness of tax administration, broadening the tax base, and enhancing human resource quality through education, healthcare, and economic empowerment programs, in order to sustainably improve the tax ratio.</span></p> Florida Salvi Aso Sri Yani Kusumastuti Copyright (c) 2026 Florida Salvi Aso, Sri Yani Kusumastuti https://creativecommons.org/licenses/by-nc/4.0 2026-08-02 2026-08-02 5 2 10.56107/penanomics.v5i2.323 http://penajournal.com/index.php/PENANOMICS/article/view/324 <p><span style="font-weight: 400;">Project management plays a crucial role in ensuring the successful completion of projects across various industries. The project lifecycle consists of multiple phases, each requiring effective management to achieve project objectives. This study aims to analyze the critical success factors (CSFs) that influence project performance throughout the project lifecycle. A quantitative research approach was adopted using a structured questionnaire distributed among individuals involved in project management activities. The collected data were analyzed to identify the most significant factors contributing to project success. The findings indicate that factors such as effective communication, leadership, stakeholder involvement, and proper planning significantly impact project performance across different lifecycle phases. The results of this study provide valuable insights for project managers and organizations in improving project execution and achieving successful project outcomes.&nbsp;</span></p> Muhammad Akmal Izat Sallaudin Hassan R.
