Planning an on-grid solar energy generation system for the Dwimatama pier at Tanjung Emas port

Global warming is the gradual increase in the temperature of the earth's atmosphere caused by increasing levels of pollutant gases such as carbon dioxide. Natural characteristics are expected to change as the earth's surface temperature rises. By 2025, Indonesia's renewable energy use is expected to reach 23%. (Ministry of Energy and Mineral Resources, 2021). Existing critical sectors such as transportation and freight forwarding are being examined. For instance, vessels can reduce their carbon footprint by connecting to shore-connection facilities powering renewable energy sources in ports. The case study is the Dwimatama pier in Semarang's Tanjung Eams port. The city of Semarang receives approximately six hours of sunlight per day. The solar power plant could serve as a source of electrical energy in this region. The results of this study indicate that to generate electrical energy from 1 MWp of solar radiation, a panel area of approximately 1 hectare is required for a solar panel with a 20% efficiency.
