A lecturer from the Department of Electrical Engineering, Faculty of Engineering, Diponegoro University, Ir. Mochammad Facta, S.T., M.T., Ph.D., served as one of the speakers at the Innovation Talk 2026 event, which focused on the utilization of rooftop photovoltaic (PV) systems as a strategic instrument to support the 100 GW program and the resilience of the national power system. The event was held at the PLN Central Auditorium in Jakarta on Saturday, April 25, 2026 and attended by various stakeholders in the energy sector, including government officials, industry representatives, academics, and renewable energy associations.
In his presentation, Ir. Mochammad Facta, S.T., M.T., Ph.D. explained that economic growth goes hand in hand with an increase in electricity demand, making sustainable solutions such as the implementation of Rooftop Solar Power Plants (PLTS) necessary. Roof-mounted solar power plants can be applied in various forms, ranging from solar home systems for houses and buildings to standalone systems to supply electricity for fishing boats.
Furthermore, he emphasized that the integration of rooftop solar power plants into the electrical grid requires careful planning and the selection of appropriate technology. This is important to ensure that the integration of solar energy does not weaken the existing electrical system, but rather enhances the resilience and reliability of the national electricity supply.
The event was also attended by UNDIP Vice Rector for Cooperation and Innovation Wijanarko, Ph.D; PT. PLN Distribution Director Arsyandani Ghana Akmalaputri; Chair of the Indonesian Solar Energy Association Mada Ayu Hapsari; Director of Renewable Energy at the Ministry of Energy and Mineral Resources Dr. Ir. Hendra Iswayudi; Ahmad Syauki, Strategic Distribution Planning Manager at PT. PLN; solar energy practitioner Sukoco from the Merah Putih Cooperative; and Indonesian renewable energy and electricity advocates.
Through this participation, the Department of Electrical Engineering at the Faculty of Engineering, UNDIP, demonstrated its commitment to actively contributing to the development of renewable energy and the strengthening of a sustainable national electricity system.
