Abstract

As the Eid Al-Fitr Holiday approaches, the public’s demand for cash increases significantly, especially for Holiday Allowance. This situation is often exploited by irresponsible individuals to circulate counterfeit money. This article discusses the strategic role of the central bank in combating the increased circulation of counterfeit money that occurs each Eid. Through qualitative methods and a descriptive approach, this research examines secondary data from various sources, including official reports from the central bank. The study results show that the central bank actively maintains economic stability through currency verification services, providing expert testimony in legal processes, strengthening the security features of new currency, and educating the public through the Love, Proud, Understanding Rupiah program. The decrease in the ratio of counterfeit money from year to year reflects the success of the preventive and educational measures taken by the central bank.

Abstract

Pertamina’s monopoly over aviation fuel and domestic fuel markets drives high prices and poor fuel quality, exacerbated by systemic issuesw This study examines the impacts of Pertamina’s monopoly, using a literature review, simple regression, and real-time data from Trading Economics, Statista, ESDM, supported by 10 monopoly-focused journals. The 2025 corruption scandal (Rp 193.7 trillion loss) reinforces monopolistic inefficiencies, with overpriced imports (Rp 11.7 trillion) strengthening avtur dominance, raising aviation costs by 10-15%. Monopoly-driven quality omission increases pollution by 8% (Rp 8 trillion health costs). Global oil prices fell 13.86% (Brent USD 64.35/barrel, June 2025), but domestic fuel prices only dropped 4.85% (Pertalite Rp 12,100/liter) due to monopolistic pricing and low elasticity (0.35). Weak KPPU oversight and UU No. 5/1999 enforcement worsen inefficiencies. Blockchain-based supply chain transparency could reduce losses by 20-30%, fostering competition.
