Petrokimia stadium or Stadion Tri Dharma in Indonesian is the main sports venue of the city of Gresik in East Java. It is primarily used to host the matches of local football side Persegres Gresik United who formed in 2005.
Petrokimia Stadium was constructed in the typical Indonesian mould which means that it features an athletics track around the perimeter of the pitch, and owing to the warm climate of the country the majority of seats are uncovered.
Designed as an outdoors stadium with only the main stand featuring coverage from the roof, the ground is capable of accommodating 25,000 spectators per match which makes it medium sized within the context of the Indonesian Super League.
The highest profile fixture played at Petrokimia Stadium to date was arguably the Asian Champions Cup match back in 2003 which featured resident side Petrokimia Putra.
In 2005 Petrokimia Putra merged with long time rivals Persegres Gresik to become Persegres Gresik United. Since merging on the 2nd December, the newly formed team has continued to play its matches at Stadion Tri Dharma.
Despite being privately owned by the Indonesian fertizeler company PT. Pupuk, the ground is home to the offices of Gresik’s Football Association.
