Pak Tjia, as his students used to call him intimately, was born on December 25, 1934 in Probolinggo, Indonesia and passed away on Nov 5, 2019. He was a Physics Professor of Bandung Institute of Technology (ITB), the initiator of main conference in the field of modern optics in Indonesia: the International Symposium on Modern Optics and Its Applications (ISMOA) series, the co-founder of the Indonesian Optical Society (InOS), and Chairman of InOS for 2011-2013 period. Together with several colleagues, he also co-founded the Postgraduate Program in Optoelectronics and Laser Applications at the University of Indonesia in 1976. He was also a co-founder of the Physical Society of Indonesia in its conception in 1973. He was a research fellow of International Centre of Theoretical Physics (ICTP) in 1974 and JSPS in 1980. Until the end of his life, he was also an editorial board member of the Journal of Nonlinear Optical Physics and Materials since 2004.
He was a person who was simple, full of dedication, full of idealism, and very consistent in advancing science in Indonesia. From his fatherly hands, born many Indonesian young scientists who were inspired to continue his idealism.
Pak Tjia completed his Bachelor of Physics from ITB in 1962, and continued to Northwestern University, United States until he reached his Ph.D. in 1969 in the field of particle physics. Gradually, his research interests were shifted to modern optics, laser spectroscopy, conjugated polymers, and superconductors, which he worked on productively until the end of his life. Scopus’ records show that Pak Tjia has filed 158 publications in international journals, with 722 citations, and in collaboration with 157 co-authors which produced an h-index of 21. Pak Tjia never retire in giving contribution for science. After his retirement as a professor from ITB 2005, he still actively involved in supervision of students in Research Division of Physics of Magnetism and Photonics, ITB and involved in research on laser induced breakdown spectroscopy in Maju Makmur Mandiri Research Center, Jakarta.
Pak. Tjia was a senior member of The Optical Society (OSA) and has received several awards. In 2007, he was the recipient of “Anugrah Sewaka Winayaraha” award from Indonesian government for distinguish services to higher education in Indonesia. In 2009 he was awarded the “Ganesa Cendikia Widya Adiutama” award from Bandung Institute of Technology for unusually wide ranging internationally published research contributions in material physics. He was the recipient of “Achmad Bakrie Award 2012” award from Freedom Institute for exceptional contribution to scientific research output of Indonesia and the development of research culture in Indonesia, and the “Sarwono Award 2016” award from Indonesian Institute of Sciences (LIPI) for outstanding contribution to the results of scientific research and dedication in developing a research culture in Indonesia.
Pak Tjia, thank you for your dedications, contributions, and inspirations.
