Persija vs Persib Derby: The Red Line Named Kanjuruhan

A day before the whistle blew at match week two of the 2026/27 Liga 1 season, Erick Thohir stood before the Indonesia Sport Summit and said something that made the hall hold its breath: do not let Kanjuruhan happen again. The PSSI chairman mentioned no tactical formation. He did not discuss form or the title race. He placed supporter safety above the rivalry between Persija Jakarta and Persib Bandung. When the whole commentary box was talking about lineups and scorelines, I heard the very quiet breathing of a nation still haunted.

Persija and Persib are more than two clubs. They are two monuments of Indonesian football, representing Jakarta and Bandung, and two of the largest supporter communities in Southeast Asia — The Jakmania and Viking. For decades this fixture has carried intense tension because it is tied to regional identity and a pride that cannot be conceded. This is a match nobody can watch with neutral eyes.

But another memory casts its shadow over the coming game. On October 1, 2026, the Kanjuruhan tragedy in Malang killed more than 135 people after rioting and a crowd crush during a match between Arema FC and Persebaya Surabaya. It was one of the most serious disasters in world football history. Since then, every major Indonesian derby has been watched with caution, and every security decision weighed as if the whole sport were facing an exam.

Match week two of the 2026/27 Liga 1 puts Persija at home. This is not a title decider, not a final, not a match that settles a continental ticket. Yet it is wrapped in an alert-level security apparatus, in meetings between police and supporter groups, and in a public warning from the head of the federation. Notably, the Persija–Persib rivalry does not depend on league position. Although the season has only passed its first round and standings are still taking shape, the tension remains intact. It lives in identity, in collective memory, in decades of off-field clashes. When an ordinary fixture is treated as a high-risk event, the question must be why.

According to released information, the Bekasi Metro Police and PSSI coordinated closely. The Jakmania and Viking groups were brought into the process — they could be a source of conflict, or a force for peace. This is a security governance model many Southeast Asian leagues are studying, but few implement as thoroughly as this.

Erick Thohir stressed that all violence and provocation will be handled by law. He made clear he had agreed with police on prosecuting troublemakers. The line sounds simple, but it marks a shift in thinking: Indonesian football is trying to criminalize violence, turning it from a stand affair into a court affair.

Organizationally, local police coordinating with the stadium operator and supporter groups shows a multi-layered approach. Rather than only erecting fences and watching, authorities worked directly with those capable of causing trouble. This is a basic principle of crowd management: you do not control a crowd from outside, you negotiate with it from within.

My contrarian angle sits here. For years, people said Indonesian football lacked money, infrastructure, professionalism. But the root cause before Kanjuruhan was not money. It was a governance system that let crowd emotion spiral beyond control, let hostility pass from generation to generation through derbies, and let authorities react only after blood had been spilled. What PSSI is doing now — speaking first, warning first, coordinating first — is an attempt to fill that gap.

What stands out is how the message travels. No club spoke up. No opposing voice came from supporters. Media reported in one direction: PSSI has spoken, and everyone should comply. This silent consensus is a double-edged sword. It shows the federation controls the story, but also that fans' voices are not yet balanced in the dialogue.

Broadly, the consequences of this match reach beyond Indonesia. A high-risk derby played safely would strengthen PSSI's standing before the AFC and FIFA, which have watched Indonesian football closely since Kanjuruhan. Conversely, a fresh incident could bring heavy sanctions, even the threat of suspension. That is why the warning was delivered at a national forum, not in a closed technical meeting.

At 55, I still believe in what you call illusion — and then it comes true. But that belief must come with clarity. And clarity tells me legal threats, however necessary, are not enough to keep a derby safe.

Look at practical risk management. Police are reinforced, but how are stands segregated? How are tickets controlled? Are alcohol bans, hard-object bans, and traffic routing around the stadium in place? These measures do not appear in the story being told. Perhaps they are in place and simply too obvious to report. Perhaps they are not strong enough. The old footage sits there, I put on my glasses, and I see the future — and that future depends on the smallest details, not the loudest statements.

Erick Thohir's warning, in the end, is a document recording responsibility. If something goes wrong, people will say: we warned. If nothing goes wrong, people will say: because we warned. Both scenarios favor the one who warned. That does not make the effort fake, it only means we should judge it by what happens on the ground, not by the volume of the statement. The Shanghai derby shock did not teach me how to win, it taught me how to look back. When I attacked a striker's play based on data, I learned that the truth on the pitch is always more complicated than a headline. For Indonesian football, that truth lives in the stands, on the roads leading to the stadium, in the psychology of a crowd carrying both pride and grieving memory.

If this derby passes peacefully, it will be a small but memorable milestone — proof that Indonesia can stage a high-risk match without paying in blood. If not, every warning will become evidence of a failure foretold. Football does not need more commitment ceremonies. It needs stands where people come to cheer and return home whole. For the organizers of this derby, and for Indonesian football as a whole, the measure of success today is not on the scoreboard.
