Biography
Hary Gunarto, born in 1954 in Surakarta, Indonesia, is an Indonesian computer engineer, scientist, writer, researcher, and professor emeritus at Ritsumeikan Asia Pacific University in Japan. His career is notable for work in computer networking, programming, simulation, and ICT applications in business and social sciences. Although he's from Indonesia, Gunarto developed most of his professional and academic career in Japan, where he became a well-known figure in ICT research and its practical uses for Southeast Asian communities.
Gunarto studied in the United States at Washington State University and the University of Wisconsin–Madison, schools known for their engineering and applied sciences programs. This American education gave him the analytical and technical skills he later applied to research in factory automation, network protocols, and digital communication systems. After his studies, he started an academic and research career that eventually led him to Japan, where he worked for many years at Ritsumeikan Asia Pacific University.
One of Gunarto's key research achievements is in factory and manufacturing computer networks. He developed and simulated a prioritized messaging protocol to ensure urgent or safety-critical signals from factory robots and sensors could cut through regular data traffic and get immediate attention. This work contributed to the Prioritized Token Bus Protocol under IEEE standard 802.4. This protocol was crucial not only for Flexible Manufacturing Systems and Computer-Integrated Manufacturing but also influenced modern smart Internet of Things networks, where fast message delivery in safety-sensitive environments is essential.
Besides his engineering research, Gunarto has worked to make ICT knowledge more accessible for Indonesian-Malay speakers in Indonesia, Malaysia, Singapore, and Brunei. He wrote a book about information technology to address the lack of language-appropriate resources for new computer terminology in ICT and Internet news in these countries. This effort showed his dedication to making technical knowledge available to non-English-speaking communities navigating the rapid digital change. His publications cover topics such as computer networks, programming, simulation, and digital media technology.
Before Fame
Hary Gunarto was born in 1954 in Surakarta, Central Java, Indonesia, when the country was still building its national institutions and educational infrastructure. In a place where advanced technical education in Indonesia was limited, many people like Gunarto sought higher education abroad. He followed this path and studied in the United States.
At Washington State University and the University of Wisconsin–Madison, he was part of American academic circles during the 1970s and 1980s. This was a time of rapid change in computer science and engineering, with developments in networked computing, industrial automation, and digital communication systems. These areas influenced the research questions that would shape his career. As he moved into academic life, he brought with him the technical training of American engineering education and a perspective shaped by his Southeast Asian roots.
