Abstract

This study investigates the effect of the self-assessment system, VAT restitution, and the number of taxable entrepreneurs (PKP) on Value Added Tax (VAT) revenue at the Cirebon One Primary Tax Service Office. Using a quantitative approach and 49 secondary data samples obtained from December 2020 to December 2024, the research applies multiple linear regression analysis to assess the relationships among these variables. The findings suggest that the self-assessment system contributes significantly to increasing VAT revenue. Allowing taxpayers to independently calculate, pay, and report their taxes appears to improve compliance and enhance state revenue collection. In contrast, VAT restitution shows a significant negative effect on revenue, indicating that larger refunds are associated with reduced funds entering the state treasury. Meanwhile, the number of registered taxable entrepreneurs does not significantly impact VAT revenue. This result may reflect ongoing challenges such as low compliance among businesses, reliance on tax consultants to minimize obligations, and limited understanding of tax responsibilities. The study highlights the importance of supporting effective self-assessment mechanisms and evaluating refund policies to balance fairness and fiscal sustainability.

Abstract

This research looks at the connection between a company's financial success and the tone it uses in its annual reports, specifically how an optimistic tone in the MD&A affects the market reaction. Included in the sample are 25 non-financial firms that were listed on IDX30 between 2020-2024. Natural Language Processing (NLP) text mining methods and panel data regression with an event study methodology were used to perform the investigation. The findings provide credence to signalling theory and market efficiency by demonstrating that an optimistic tone significantly impacts Cumulative Abnormal Return (CAR). Companies that have done well financially (high ROE) also have a tendency to sound more hopeful, which is consistent with agency theory. These results prove that annual report narratives are more than just filler; they are powerful instruments of strategic communication that shape how the market perceives a company. Credible and informative narrative disclosures are needed in financial reports, according to this research, which adds to the literature on developing markets.

Abstract

Accounting is a science that has its own unique features, where every country applies accounting principles in accordance with standardized international norms. Accounting plays an important role for countries as it can be considered the language of business, revealing the financial performance of enterprises. The diversity in accounting applications across nations inspired our interest in exploring the differences between Indonesian and Thai accounting practices through community service involving lecturers and students from Thai Global Business Administration Technological College Thailand (TGBC Thailand). This international community service initiative included six lecturers from Indonesia, five lecturers from TGBC, and 15 students, at TGBC. The purpose of this international community service was to educate participants about and introduce accounting practices applied in both Indonesia and Thailand. This activity is expected to provide additional insights and applications of new knowledge in the field of accounting.

Abstract

This study examines how perceived transparency and algorithmic fairness in AI-based human resource (HR) practices relate to employee performance, and whether trust in management moderates these relationships. Data were collected through a quantitative cross-sectional survey of 152 employees from Indonesian service organizations using AI-enabled tools in HR decision processes, and analyzed using partial least squares structural equation modeling (PLS-SEM) with bootstrapping. The results show that perceived algorithmic fairness and trust in management have positive and significant relationships with employee performance, whereas perceived transparency does not have a significant direct effect. Trust in management also strengthens the positive relationship between perceived algorithmic fairness and employee performance, but does not significantly moderate the relationship between perceived transparency and employee performance. These findings suggest that organizations seeking performance benefits from AI-based HR should prioritize fairness governance and trust-building managerial practices, while designing transparency as meaningful, employee-relevant explanations rather than merely technical disclosure.

Abstract

This study examines the effects of work-life balance (WLB) and perceived organizational support (POS) on organizational citizenship behavior (OCB), with burnout as a moderating variable. Using a quantitative cross-sectional design, data were collected through a questionnaire survey of 150 service-sector employees in Jakarta, Bekasi, and Tangerang and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings show that WLB and POS have significant positive effects on OCB, whereas burnout has a significant negative effect. Burnout also significantly weakens the positive effects of WLB and POS on OCB, indicating that employees are less likely to engage in extra-role behavior when they experience higher levels of exhaustion. The model demonstrates strong explanatory power (R² = 0.842). These findings suggest that organizations should strengthen work-life balance practices, enhance organizational support, and implement structured burnout prevention strategies to sustain employees’ extra-role behavior.
