Gudskul: Collective and Contemporary Art Ecosystem Studies is an educational platform formed by three Jakarta-based collectives: ruangrupa, Serrum and Grafis Huru Hara. Since the early 2000s, we have been respectively doing collective practice in the contemporary art scene. In 2015, we joined forces to form a common ecosystem, Gudang Sarinah Ekosistem. Learning from this working experience, in 2018 Gudskul outlines a knowledge-sharing platform for everyone interested in the practice of similar approaches.
