Sahat Hutajulu officially holds a doctorate in management science with cum laude. The dissertation examiners were from the School of Business and Management (SBM) ITB and representatives from the Ministry of Communication and Information.
In the Doctor’s promotion examination, Sahat succeeded in defending his dissertation entitled “5G technology Development Framework for Indonesian Telecommunication Industry Using Scenario Planning and Agent-Based Modeling,” via a zoom meeting, Thursday (23/9/2021).
Armed with axial coding & scenario planning, and agent-based modeling, Sahat proposed a framework for developing 5G technology in Indonesia. This study is motivated by the fact that Indonesia is lagging behind other countries in the development and commercialization of 5G technology.
5G technology itself is a 5th generation cellular technology designed to increase speed and service flexibility. Sahat said that Indonesia recently switched to 5G technology (May 2021), in contrast to other countries, such as China, which had already switched to 5G technology and planned to move to 6G. “Indonesia itself has just launched 5G commercially on May 27, 2021,” added Sahat.
Sahat Hutajulu, who completed his undergraduate education in Electrical Engineering ITB and more than 14 years experience in telecommunication companies, revealed the challenges for Indonesia to develop 5G technology. These challenges include, the need for high investment, disintegration with local governments, high demand for optical fiber in remote areas, high-frequency spectrum requirements, limited application, and innovation.
To overcome these challenges, through his dissertation, Sahat tries to develop a framework that can later be used as a basis for policymakers to develop 5G technology in Indonesia. “From these challenges, we made a research question about how Indonesia can successfully develop 5G technology that brings benefits to the country,” said Sahat.
Furthermore, in his dissertation promoted by Prof. Wawan Dwanto, S.T, M.Sc., Ph.D., Sahat developed a 5G development framework consisting of three stages. The first stage is the initiation stage, where 5G technology comes to Indonesia, so that Indonesia needs to apply a scenario for the development process. The second stage is the internalization stage, where at this stage, it is important for collaboration between stakeholders in infrastructure and the importance of the technology commercialization process to form an ecosystem. And the last stage is the diffusion or generation stage.
The dissertation examination was examined by Dr. Leo Aldianto, M.B.A, M.SAE, and Prof. Dr. Ir. Sudrajati Ratnaningtyas, M.P from SBM ITB and the examiner from Ministry of Communication and Information, Dr. Denny Setiawan. “Your paper provides a good insight for us to develop the 5G concept in Indonesia,” said Denny praising Sahat’s dissertation.
