Selayar Island is one of the islands in South Sulawesi Province. This island is about 40 km from the island of Sulawesi. On this island, there are about 88500 people who live as farmers and fishermen. Even though they live as farmers and fishermen, they use electrical energy as an energy source for their daily needs. Currently, electrical energy comes from Diesel Power Plant (PLTD) with a nominal capacity of 13.19 MW, where the PLTD burns diesel oil every day. Currently, there is a policy from the Government that will stop the use of diesel oil so that the PLTD on Selayar Island will be replaced with a 20 MW Gas Engine Power Plant (PLTMG). Selayar Island is an island that has great tourism potential, so it is necessary to think about providing clean and continuous electrical energy. Another alternative besides PLTMG is the use of 20 kV submarine cable networks. The use of the network will integrate the South Sulawesi electricity system and the Selayar Island electricity system. 20 kV submarine cable network as an alternative that Selayar Island does not have to build a thermal type power plant. So, this paper aims to explain the choice between building a PLTMG or supplying electricity via submarine cables on Selayar Island. [ABSTRACT FROM AUTHOR]

The operation of a university is strongly influenced by the availability of electrical energy. So that currently, electrical energy is one of the absolute and unavoidable basic needs of universities such as Hasanuddin University (Unhas). This is because at Unhas, there are modern learning and practicum facilities, both for the learning process, academic administration needs, and teaching media that generally use electrical energy-based equipment. Prior to the Covid-19 pandemic, Unhas's electricity consumption was relatively high. From 2018 to 2019, the average amount of electrical energy consumption was 14.3 GWh per year. Since entering 2020, the consumption of electrical energy has decreased to an average of 4.3 GWh. The decrease in usage is because at Unhas, there is often a policy of working from home for employees and lecturers, and studying at home for students. The decrease of 4.3 GWh was due to the absence of student activities at Unhas. So that it can be illustrated that the use of electrical energy of 4.3 GWh is an academic administrative activity. This paper aims to deliver an overview of the impact of covid 19 on the decline in electricity consumption at Unhas. [ABSTRACT FROM AUTHOR]
