The Jakmania is one of the biggest football fan groups in Indonesia and use orange as their main colour, even though the club have since switched to red.

Another tragedy happened on September 23, 2018, when before a Liga 1 match between Persija and Persib began at the Gelora Bandung Lautan Api Stadium, Haringga Sirla, a Jakmania member, was killed by some unscrupulous Vikings.

In response to the incident, the Football Association of Indonesia (PSSI) suspended Liga 1 for two weeks and forced Persib to pay a IDR 100 million (US$6,634) fine and play the remainder of their home matches of the 2018 season behind closed doors.

The dark past makes these two supporters difficult to unite, even to the point that there is a slogan, "Biarkan Permusuhan Ini Tetap Abadi", which means, "Let This Feud Remain Eternal" from one of the main figure Bobotoh frontman.

Following the Kanjuruhan Stadium disaster, Persija and Persib supporters participated in prayer ceremonies in Jakarta and Bandung while proudly wearing the club's attribute.
