Persija vs Persib: When the Kanjuruhan Lesson Becomes the Rule of the Derby

THE NIGHT BEFORE

Late in the afternoon in eastern Jakarta, a crew of welders raises steel barriers along the road leading to the stadium. They work in silence: measuring, cutting, bolting. One of them answers a phone call, says he will come home once the barrier stands firm, and hangs up. He does not say a word about football. He talks about the meal going cold at home.

A few hundred metres away, in a room with maps spread across a table, another meeting is under way. Duty rosters, crowd-flow diagrams, emergency contact lists. And one line repeated like a prayer: put supporter safety above everything else, including above the rivalry.

Tomorrow, Persija Jakarta play Persib Bandung. Match week two of the 2026/27 Liga 1 season. An ordinary fixture on the calendar, and a thoroughly unordinary one in the memory of a nation.

I have spent much of my career standing in places like this before kick-off, when the gates are still shut and the air is already thick. I learned one thing: what happens in the final twenty minutes of a derby is usually decided long before, in rooms without cameras. The pulse is never in the ball. It is in the people.

TWO CITIES, ONE SCAR

Persija Jakarta and Persib Bandung are two of the most heavily supported clubs in Southeast Asia. Their meeting is dressed up as the El Clasico of Indonesia, but that name conceals a harsher reality. This is a fixture that organisers do not assess by form, by league position, or by any technical measure. They assess it with a single question: will everyone who is here tonight get home?

Jakarta and Bandung sit about one hundred and fifty kilometres apart by road. Geographically, the distance is small enough to cover in a single afternoon. Culturally, it is far wider. The Jakmania, Persija's supporter base, grew out of the rhythm of the capital: fast, loud, crowded, tied to pavements and alleyways. Viking, Persib's supporters, carry the temperament of a highland city where football is the thread between generations of the same family.

For more than three decades those two communities have collided. Some collisions were only flares and taunting songs. Others left injuries, prison sentences, and deaths on the motorway after the final whistle. Indonesian football has lived with that fear for so long that it has become part of its identity: people love their club, and they know that love can be paid for with a life.

The name Bekasi appears in this round of safety planning. For anyone who follows Indonesian football, that is a detail worth noticing. Bringing a specific district's police force into the coordination list suggests organisers are thinking about flashpoints outside the stadium walls: junctions, bus terminals, rest stops, and the roads supporters travel before they ever reach their seats.

KANJURUHAN, 1 OCTOBER 2026

To understand why a safety statement carries so much weight, you have to go back to Malang, East Java, on the night of 1 October 2026.

That evening, Arema FC hosted Persebaya Surabaya at Kanjuruhan Stadium. Another derby, another rivalry with history. After the home side lost, a section of the crowd spilled onto the pitch. Police responded with tear gas. In an enclosed space, between narrow exit gates and a crowd moving in opposite directions, the gas turned a shove into a catastrophe. More than 135 people died, among them children and women. Most victims suffocated in the crush rather than dying from direct violence.

Kanjuruhan became the deadliest event in the history of Indonesian football, and one of the worst stadium disasters world football has recorded in decades. It forced the game to ask questions nobody had wanted to ask: who is responsible, which procedure failed, and is a football match worth a human life?

What followed was a chain of change. The Indonesian Football Association (PSSI) restructured its leadership. Erick Thohir, who had once run a major European club and carries weight in regional sport, became PSSI chairman. Stadium safety regulations were tightened. For fixtures classed as high risk, the away section is often closed, a precaution widely applied across Liga 1.

I once wrote that a stadium without fans is still a stadium where you can hear applause from distant balconies. That was true of the pandemic years, and it is true of Indonesian football after Kanjuruhan in a different sense. There, the terraces went quiet not because of a virus, but because of fear, administrative decisions, and a distrust that has not yet been resolved.

A WARNING READ ALOUD

What happened before this Persija-Persib fixture was delivered publicly from a formal stage, at the Indonesia Sport Summit. PSSI chairman Erick Thohir spoke, invoked the Kanjuruhan disaster as a national lesson, and stated that acts of violence and provocation would face legal proceedings. He made clear that PSSI had agreed with the police on pursuing offenders under the law.

Read closely, the message carries three layers.

The first is safety. This is the most direct layer, aimed at the majority: come to the stadium, support your team, and let the rivalry stop at the singing.

The second is legal accountability. Naming the police and legal procedure creates a paper trail of responsibility. If something happens after this warning, nobody can claim they were not told. It is how sports organisations protect themselves, and also how they apply pressure to supporter groups.

The third is reputation. For a country trying to prove its football has changed, a major derby played safely is an asset. It is not just an organisational win. It is evidence to present to regional and international federations.

Based on my experience covering high-risk fixtures over many years, statements like this share a trait: they are strong on language and thin on technical detail. People talk about resolve, sanctions, lessons. They rarely talk about the number of exit gates, the timing of gate openings, crowd segregation, or who has the authority to order tear gas, and under what conditions.

That is why a safety statement, however grand the stage, is only the beginning of the story.

THE NINETY MINUTES AFTER THE WHISTLE

There is a rule anyone who has organised an event knows, and anyone who has written about stadium disasters must remember: accidents rarely happen while the match is being played. They happen when it ends.

For ninety minutes, a crowd is held in a naturally ordered state. People sit, stand, sing, and their eyes are fixed on a shared point. When the final whistle goes, that structure collapses in seconds. Tens of thousands of people want to leave at once, through the same few gates, down the same stairways, towards the same car parks. Emotions are still running at maximum, and there is nothing left to aim at.

At Kanjuruhan, that was the fatal moment. Supporters spilled onto the pitch, police reacted, and the crowd was compressed against exit gates never designed for an emergency. Tear gas did not create the crowd, but it turned the crowd into an uncontrollable mass of panic.

So when I assess how safe a derby really is, I look at what never makes the statement: the exit plan. How many gates open after the whistle? How wide are they, and where do they lead? How many stewards stand there, and are they trained to talk to a crowd or only to give orders? In a worst-case scenario, who holds decision-making authority, and how many seconds does that decision take to travel from command level to the person at the gate?

A steel barrier erected before kick-off is a signal. But a barrier is only worth something when it does not become a trap. The history of stadium disasters worldwide, from old European grounds to vast Asian arenas, tells one story: fences are built to keep people out, and then become the thing that keeps people in.

Here, the complicating factor is supporter culture. Indonesian football has an exceptionally strong terrace culture, with organised supporter groups that have leadership, history and standing in their communities. The Jakmania and Viking are not anonymous crowds. They are miniature social institutions, capable of mobilising thousands within hours, and capable of controlling thousands if they choose to.

That is why police working with supporter groups is a positive signal. It is also a gamble. When you hand a supporter group a crowd-control role, you admit the state cannot do the job alone. And you bet that the group will choose cooperation over asserting status against its rival.

WHEN METRICS LIE

In my trade there is a constant temptation: turn everything into numbers.

Number of police deployed. Number of stewards. Number of cameras. Number of barriers. Number of tickets sold. These figures appear in reports, statements and post-match interviews. They produce a comfortable sense of safety, because they can be measured, compared and presented.

But I have learned, after years of reading such reports, that a good metric does not equal a good reality. A match can be surrounded by five thousand officers and still end in catastrophe, if those five thousand stand in the wrong places. A stadium can have hundreds of cameras and still have nobody who knows what to do when a crowd starts moving the wrong way.

Football is used to measuring effort with neutral numbers: distance covered, sprints, duels. A player can run twelve kilometres in a match and create nothing of value. A team can post the highest pressing numbers of the round and still lose by three. What is measured is not always what matters.

The same holds for event safety. Publishing force numbers is a communication act, not a guarantee. The real question is not how many people were deployed, but what logic deployed them. A line of officers along the touchline can look impressive on television. If the crowd decides to move in another direction, that line becomes a meaningless wall.

With Persija-Persib, I would not be surprised if we get a report full of numbers afterwards. Attendance, force strength, incidents handled. Those numbers will be presented as proof of success. In many cases they genuinely are. But they only mean something if we also learn what nearly happened, and what was never considered.

Tactics will age. Human stories never expire. That is true of a formation, and it is true of a safety plan.

SUPPORTERS AS CITIZENS

There is a blind spot in the way modern football talks about fans.

When a fixture is classed as high risk, the language used is the language of risk management. Supporters become a factor to control, a variable to predict, a threat to prevent. They are mentioned as a group, never as specific human beings.

But Indonesian football fans are not merely a risk factor. They are people who lived through a national disaster. They are people who lost brothers, friends and neighbours on the night of Kanjuruhan. They are people who for years have asked to be heard on stadium safety conditions, on the quality of exit routes, on the responsibility of organisers.

In the source material for this fixture, I looked for the voices of supporters themselves. I did not find many. That does not mean they are silent. It means they were not brought into the story as people with a voice, but as people being spoken about.

I came to Lyon chasing a media wave, and I stayed to learn how to listen. That is a personal journey, but it is also a professional principle. When a community has just been through a disaster, the first thing a writer should do is not explain them, but let them explain themselves.

This has practical meaning, not just moral meaning. A safety strategy built without the participation of the very people who will stand on the terraces is built on an assumption. That assumption may be right. It may also be wrong, and the cost of being wrong is irreversible.

In many countries, organised supporter groups have become formal partners in safety work. They receive information, training, and a role in pre-season drills. In return, they take responsibility for their members' behaviour. That model is not perfect. It can be exploited, politicised, divided. But it acknowledges a truth: any safety plan must begin by understanding the people it is trying to protect.

WHAT TO WATCH

With a fixture like Persija-Persib, the scoreline will be discussed for a few days. What remains will last far longer.

First, watch the window between the final whistle and the moment the area around the stadium returns to normal. That is the real risk window, and it rarely appears in official reports.

Second, watch the first reactions from the supporter groups themselves. If The Jakmania and Viking speak about safety before they speak about the result, that is a sign terrace culture is shifting. If the opposite happens, the Kanjuruhan lesson still has a long road ahead.

Third, watch whether a post-match report is made public. A mature football culture is measured not only by how it handles disaster, but by whether it dares to talk about what nearly happened.

I write from the inside, where outside noise cannot touch the pulse. And from the inside, what I hear now is not the singing of a hundred thousand people. It is the voice of a welder hanging up his phone, preparing to go home and eat with his daughter, now that the barrier stands firm.
