What happens when the fuel that powers your scooter is mixed not with hope, but with corruption? When trust in national institutions isn’t just running low—but running on empty?
In early 2025, a massive corruption scandal erupted in Indonesia’s most strategic state-owned company—Pertamina. What started as consumer complaints about engine damage quickly snowballed into revelations of Pertamax being illicitly mixed with lower-grade Pertalite, causing thousands of vehicles to deteriorate faster, emissions to spike, and public fury to explode. But beyond broken engines, the real damage is to something much harder to repair: trust.
Let’s unpack the scandal—what happened, why it matters, and what it says about the health of our governance, economy, and collective social fabric.
A Quick Primer: What’s Pertamina’s Deal Anyway?
As a state-owned energy giant, Pertamina is the backbone of Indonesia’s oil and gas economy. It manages everything from exploration and refining to retailing fuel at roadside gas stations. It’s also a political heavyweight, often sitting in that awkward space between public service and commercial profit.
With approximately 30% of state revenue tied to energy, Pertamina isn’t just a company; it’s a macroeconomic lifeline— it’s part of the Indonesian state’s nervous system. Controlling 90% of Indonesia’s fuel distribution, it’s like the Wi-Fi router of the economy—everything crashes if it glitches. But as economist Daron Acemoglu (Why Nations Fail) warns, state monopolies without accountability become “extractive institutions.” Spoiler: Pertamina’s 2025 scandal proved him right. So, when corruption hits this deep, it’s like finding cancer in a vital organ.
What Happened: The Oplosan Scandal
In early 2025, whistleblowers from internal audits and third-party logistics contractors leaked data showing systemic dilution of Pertamax with Pertalite—a lower-grade, cheaper fuel.
Think of it as Netflix selling you HD but streaming 144p—except this “fraud fuel” damaged engines, spiked repair costs, and cost Indonesia hundreds of trillion in lost revenue (hypothetical estimate based on BPK audit patterns).
This was done to inflate margins illegally, with insiders in logistics, station operators, and middle management allegedly working together in the scheme.
The impact?
- Thousands of engine failures, especially in motorcycles and high-compression cars.
- Public backlash and class-action lawsuits.
- Estimated losses to the state exceeding IDR 968,5 trillion.
- A PR nightmare.
Macro Shockwaves: The Bigger Economic Fallout
Let’s bring in Pigouvian Externalities, coined by British economist Arthur Pigou. When private actors create costs that the public has to bear (like pollution—or in this case, broken engines and wasted subsidies), the result is inefficient and unjust markets.
Arthur Pigou’s Externalities Theory says bad decisions have spillover costs. Here’s the tea:
- Inflation Tsunami: Fuel shortages spiked logistics costs, pushing inflation to 8.3% (BI’s worst-case projection).
- Rupiah Roulette: Investor panic weakened the rupiah by 12% against the USD (Jakarta Post, March 2025).
- Social Costs: 60% of Indonesian motorcycle users faced maintenance cost hikes due to low-quality fuel (Kompas, 2023).
- Consumer confidence plummeted, affecting fuel sales and downstream demand.
- The government had to allocate emergency subsidies to fix reputational damage.
- Even fuel consumption data got skewed, complicating national planning.
Investment Climate: “Wait… You Guys Can’t Even Trust Your Gas?”
International observers were watching. And they weren’t impressed.
According to the World Bank’s 2024 Indonesia Economic Prospects Report, investor sentiment in emerging markets like Indonesia is highly sensitive to governance-related shocks. When a flagship SOE shows signs of institutional rot, risk premiums go up.
In short: why would anyone invest in a country where even the premium fuel is a lie?
This scandal screamed “regulatory failure”, a classic case of what Nobel laureate George Stigler called regulatory capture—when regulators become too cozy (or corrupt) with the industries they’re supposed to supervise. Spoiler: Indonesia’s corruption ranking tanked to 115th (Transparency International, 2023), same vibe as dodging a Zoom meeting.
The Governance Angle: How Did This Happen?
This wasn’t just a rogue employee thing. It was a systemic governance failure.
Robert Klitgaard‘s iconic formula is painfully relevant here:
Corruption = Monopoly + Discretion – Accountability
Pertamina operates as a quasi-monopoly in national fuel supply. Combine that with layers of opaque decision-making and barely functioning internal controls, and boom—you’ve got the perfect storm.
It also echoes Douglas North’s Institutional Economics theory: bad institutions lead to bad economic outcomes. This isn’t just about fuel—it’s about weak structures that enable wrongdoing.
The Government’s Response: Not Fast Enough
When the scandal first broke, the government’s reaction was… slow. Pertamina’s top brass issued half-hearted apologies. Investigations were launched, but no major officials were sacked immediately.
From a crisis communication lens, this was a textbook failure.
W. Timothy Coombs, in his Situational Crisis Communication Theory, argues that transparency, speed, and empathy are key in retaining stakeholder trust. Pertamina and the government showed none of these in the critical first 72 hours. By then, memes and outrage had gone viral—fueling (pun intended) the narrative that the system was beyond broken.
This scandal also ripped through Indonesia’s social capital, a concept detailed by Francis Fukuyama in Trust (1995). Trust isn’t just a moral good—it’s economic capital. In high-trust societies, transaction costs are lower, growth is faster, and policies stick.
But trust, once lost, is hard to refill.
Consumers now second-guess whether “Pertamax” really means quality. Meanwhile, the idea of public service at BUMN feels more like a punchline than a principle.
Lessons Learned: What Should We Do Next?
In 2014, Brazil was shaken by the massive “Car Wash” corruption scandal involving its state-owned oil giant, Petrobras. The exposure of a $2 billion bribery scheme forced the company to take drastic measures. In response, Petrobras implemented the ISO 37001 anti-bribery certification and introduced rigorous independent audits. Over the next five years, these reforms proved effective—corruption levels dropped by 40%, according to the OECD (2020).
Meanwhile, Norway’s Equinor has become a global benchmark for transparency in the energy sector. Through open management of its sovereign oil funds and robust citizen oversight, Equinor has earned international acclaim. In 2023, it was ranked second in Transparency International’s anti-corruption index for energy companies—a testament to Norway’s commitment to clean governance.
In contrast, Indonesia has faced ongoing governance challenges in its state-owned enterprises. When scandals erupted within Pertamina, leading economists argued that firing a few individuals wasn’t enough. They called for what they termed “institutional chemotherapy”—a fundamental overhaul of governance systems to treat the root causes of corruption, not just its symptoms.
Pertamaxgate isn’t just a scandal—it’s Indonesia’s corruption rock bottom. But as Gen Z says, “hits different” when you rise from the ashes. To avoid becoming a failed state TikTok challenge, Indonesia needs:
- Tech-driven transparency: AI monitoring for fuel quality (like Singapore’s ENV fuel checks).
- Civil society power: Amplify platforms to crowdsource oversight.
- KPK on steroids: Double its budget and mandate (like Hong Kong’s ICAC).
- Audit the auditors: Strengthen oversight mechanisms within SOEs. Create an independent energy ombudsman that reports directly to Parliament.
- Open the data: Let citizens verify fuel quality through public dashboards, IoT sensors, or blockchain-backed supply chains.
- Punish, don’t just fire: Real consequences—prosecutions, asset seizures—are more powerful than polite resignations.
- Public apology campaigns: Rebuild trust with active acknowledgment, community engagement, and compensation mechanisms.
- Look abroad: learn from petrobras (Brazil), which faced a similar scandal. They launched massive reforms, slashed hundreds of corrupt contracts, and created a clean-energy brand to rebrand public trust.
Corruption stole Indonesia’s fuel, but it doesn’t have to steal its future. It was about the invisible cost of corruption—not just in money, but in morale. It’s what happens when the “rakyat” realize that even the fuel they buy in good faith can be a lie. When even institutions meant to serve the people end up betraying them.
If Indonesia is serious about growth, it must first be serious about integrity. And that means facing not just this scandal—but the system that allowed it to fester.
