Based upon research conducted among groups of young people, ketjilbergerak is of the opinion that the increasing limitation and disappearance of public spaces in Yogyakarta is an issue that must be addressed. In this work, ketjilbergerak works together with active communities in creating public spaces and simulating citizen proposals on imagined public spaces. It is anticipated that in the future the “Taman Tiban” project will occupy empty spaces in Yogyakarta.
