Kemas began working at an
architectural firm in 1995, working on house and office designs. He also worked as an assistant professor at his almamater, assisting professor Siti Utamini in the studio designing class and Budi Sukada in architecture history class. Kemas joined the Union of Indonesian Architects in 1997. On that same year, Siti Utamini offered him a full-time career as a lecturer. Kemas then left his architectural firm and became a full-time lecturer in the department. By department chair Gunawan Tjahjono, Kemas was appointed as his assistant for student affairs in 1997, and assistant for education in 1998. In 1999, Kemas conducted research on the
Jengki style with research grant from the University of Indonesia and was in charge of organizing the first International Seminar on Vernacular Settlements. The seminar, which implemented a
call for papers system, was the first of its kind for architecture departments in Indonesia. Based on the recommendation of Budi Sukada, Kemas picked
The Bartlett Faculty of the Built Environment in the
University College London for his postgraduate studies. Two years later, in 2007, Kemas was entrusted to chair the architecture department. He served for two three-year terms until 2013. During his tenure, the department established three new majors: undergraduate in
interior architecture in 2007, Doctor of Architecture in 2008, and architecture professional education in 2009. The department also assisted architecture department in state universities in Indonesia who had a surplus of senior lecturers that were unable to continue their postgraduate studies. In 2010, Kemas was elected as the chairman of the union of architecture departments in Indonesia and served until 2013. On 5 March 2019, Kemas was installed as a member of the Jakarta Regional Research Council, an agency under the governor of Jakarta responsible for assisting the governor of Jakarta in resolving problem in Jakarta based on research approaches. Kemas was elected as the council's secretary exactly a week later, and several months later he became the council's chairman, replacing Dadang Solihin who was appointed as the
deputy governor of Jakarta. During his tenure, the council assisted the Jakarta government in handling the
COVID-19 pandemic by providing assessment on projects, such as the Grha Sehat Mandiri COVID mitigation center in
Pademangan. In 2024, Kemas ran as a candidate for the rector of the University of Indonesia. In his speech, Kemas pledged to develop UI's international achievements and ranking as well as diversify its source of income. He, however, failed to pass the final selection process. On 22 January 2025, Kemas was announced as the dean of the engineering faculty of the University of Indonesia by rector—and predecessor—Heri Hermansyah after passing a series of assessments. == References ==
