After six years in the premier division, PSS was unable to complete the 2006 season after suffering from the 2006 Yogyakarta earthquake that killed more than 5,000 people and damaged thousands of buildings.
However, the Indonesian football association PSSI did not relegate the three teams from Yogyakarta province, including PSS, although they forfeited their remaining games due to the earthquake's impact on their facilities and personal lives.
Teams like PSS that continued to rely on the government had to compete in the second tier, which persistently used the Perserikatan's name for its top division (Divisi Utama).
Amid heavy pressure from fans, PSS became a professional team in 2012 after the incorporation of PT Putra Sleman Sembada, the company that now manages the club.
BCS boycotted games in the 2020 Liga 1 over disappointment with the level of professionalism in PSS and only ended its strike in 2021 after a massive restructuring that has led to improvements in how the club is managed.
The anthem symbolizes fan loyalty to the team in good and bad times, knowing the club went through trials until it earned its spot in top-flight football.
