When Indonesia declared its independence the campus was renamed "Sekolah Tinggi Teknik" (STT) (Technical High School) in 1945.[10] However a year later the Netherlands returned to Indonesia and took directorship of the campus, it was used as "Nood-Universiteit van Nederlandsch Indië" (emergency university of Dutch East Indies). Later in 1947 the campus housed the Faculteit van Technische Wetenschap (faculty of engineering) and Faculteit van Exacte Wetenschap (faculty of science) which is under Universiteit van Indonesië (later University of Indonesia). In 1950 after the Netherlands left Indonesia, the university became faculty of engineering and faculty of natural sciences, under University of Indonesia.[11]
