Prof. Ir. Gunawan Wibisono, M.Sc., Ph.D. was inaugurated as a permanent professor in the field of Telecommunication Systems Divais Science, Faculty of Engineering (FT), Universitas Indonesia (UI), after delivering a scientific oration entitled “The Role of Radio Frequency Communication Technology for Welfare”. The inaugural ceremony was led by UI Rector, Prof. Ari Kuncoro, S.E., M.A., Ph.D., on Wednesday (1/11), at the UI Makara Art Center.
In his speech, Prof. Gunawan said that the birth of 1G, 2G, 3G, 4G, and 5G mobile technology requires radio frequency (RF) transmitter and receiver (transceiver) devices that allow users’ devices to communicate with other users through the presence of telecommunications operator devices in the form of base transceiver station (BTS) devices. RF transmitter and receiver systems operating at various frequencies are the same. For RF devices to operate, they are designed using multiband concepts and resonator concepts to work according to the frequencies they run on.
Mobile communication devices can be divided into three forms, namely objects to improve their performance; developers using devices to help Internet of things (IoT) systems work; and device users. IoT is a concept that connects all devices to the internet and allows IoT devices to communicate with each other via the internet. With these devices, people can interact through devices remotely.
IoT technology layerization includes Device Layer-sensor; Network and gateway Layer-connectivity; Platform Layer-device management, security, and analytics; Application and solution Layer-smart grid, and smart logistics. The utilization of IoT technology provides great efficiency because it relies on connectivity as a communication enabler from devices/sensors on electronic devices. With an increase in connectivity, there is a decrease in the amount of time to perform the same task, thereby increasing productivity and creating a safe work environment.
Currently, IoT technology has been developed for everyday life. Some of them are Fishery to regulate the feeding of fish; COVID-19 detection to monitor the movement of COVID-19 patients; Monitoring tools for COVID-19 duty officers; and Elder People Detection to detect the presence of elderly patients who live alone.
Based on research conducted by McKinsey Global Institute in 2020, the economic value that IoT can unlock is huge and growing. McKinsey estimates that by 2030, IoT globally could generate a value of $5.5 trillion to $12.6 trillion, including the value captured by consumers and customers of IoT products and services. Services such as industry, health, office, smart city and smart building are potential businesses from the utilization of IoT.
Indonesia alone is estimated to gain a total productivity value of up to $120 billion by 2025, with the majority of revenue sectors from manufacturing, retail, transportation, mining, agriculture, telecommunications and media, and health, with the number of IoT device connections reaching up to 678 billion devices.
In the pandemic era, digital services were born and replaced analogue system services. Usually, this disruptive technology comes from startups that try to modernize the old-fashioned business style. Technology-first startups can slowly change the traditional way of doing business. This happens because large traditional companies focus on increasing sales rather than making changes, especially in terms of technology. However, on the other hand, the birth of disruptive technology also has an impact on traditional markets that are deserted as buyers move to online markets. Many application services on devices can be utilized, including for economic activities, trade, community services, and fintech (online lending) services.
In addition, the development of 5G technology also has the potential to increase Indonesia’s GDP by 2030. The Indonesian economy is expected to experience exponential growth by 2024 due to a significant increase in 5G adoption rates across all industries and consumers. GDP is estimated at IDR 2,802 Trillion in 2030 and IDR 3,533 trillion in 2035. It is estimated that 5G will contribute 9.3% to Indonesia’s GDP in 2030 and 9.8% in 2035.
“5G technology will also increase profits for various sectors, namely the service sector, manufacturing sector, and digital technology will open 20-40 million new jobs. However, to provide good results, there needs to be protection for consumers who use technology which includes personal data protection, user security, and data confidentiality,” said Prof. Gunawan.
Dean of FTUI, Prof. Dr. Heri Hermansyah, S.T., M.Eng., IPU, said, “In this digital era, radio frequency communication technology plays a very important role in bridging the gap in access to information and communication. Its impact on Indonesia and its people cannot be ignored. Advances in this technology have the potential to improve welfare, connect remote communities, and support economic growth.”
Prof. Gunawan’s research on the role of communication technology is one of many that have been conducted previously. Some of them are the Performance of Downlink NOMA for a Massive IoT Network Over a Nakagami-m Fading Channel With Optimized Power Allocation (2023); Co-design Structure of Dual-Band LNA and Dual-Band BPF for Radio Navigation Aid Application (2021); Multiwideband Bandpass Filter Based on Folded Quad Cross-Stub Stepped Impedance Resonator (2020).
Prof. Gunawan Wibisono, M.Sc., Ph.D. completed his undergraduate degree in Electrical Engineering at the Department of Electrical Engineering FTUI in 1990 and completed his Masters / S3 in Telecommunication Engineering, Keio University, Yokohama, Japan in 1995 and 1998. Currently, he serves as the Head of the FTUI S2 accreditation drafting team for LAM Engineering.
Prof. Gunawan’s inaugural ceremony was also attended by the Rector of Jenderal Achmad Yani University, Prof. Hikmahanto Juwana, S.H., LL.M, Ph.D.; Professor of Chemical Engineering at the Bandung Institute of Technology, Prof. Dr. Ir. Tirto Prakoso, M.Eng., IPM; Principal Expert Researcher of National Research and Innovation Agency, Prof. Dr. Silvester Tursilo Adi, M.Eng.; Director General of Postal and Information Device Resources, Ministry of Communication and Information, Dr. Denny Setiawan, S.T., M.T.; President Director of PT Comcore Teknologi Indonesia, Septi Maharani, S.E., M.M.; President Director of PT Jawa Satu Regas, Ir. Indra Trigha; and President Director of PT Alita Praya Mitra, Ir. Teguh Prasetya, M.T..
