Semarang State University became University of Conservation on 12 March 2012. This influences the policy-making as well as efforts in socializing and empowering the entire campus community in creating and cementing this conservation vision. There are some mottoes that are used to uphold the principle of protection, preservation, utilization and sustainable development of natural resources and cultural arts, in order to preserve the environment of this conservation campus, for example," Salam Konservasi" which means go conservation," Thousand tree-planting movement,”" Pasar Krempyeng Nyeni” which promote the Arts of Krempyeng Market," On Campus: Let’s Walk or Cycle!"," Planting Trees, Planting Hope"," Motorcycle Free". Student participation in developing the University of Conservation is one of the keys to successfully implement UNNES vision. In terms of quantity, the students occupy the largest portion compared to faculties and staffs. Reciprocal changes occurred between the environment and the languages were learned through ecolinguistics study. Ecolinguistic study examines the ecosystem as a part of the human life system (ecology) and the language used by humans to communicate in their environment (linguistics). This means the students’ attitudes towards the conservation mottoes in campus will influence personal behaviours and communities of college students in preserving the environments.
