Law Number 3 of 2022 is the legal basis for moving the National Capital from DKI Jakarta to Sepaku, East Kalimantan, which is called the Capital City of the Archipelago (IKN). To prevent serious emissions cases from recurring in the capital city of Jakarta, the low emission zone concept needs to be implemented to achieve a smart and green city area in IKN. Community mobility in IKN is directed at 80% to use public transportation with an access time of 10 minutes to public transportation nodes, so that with the large area of IKN it is very necessary to optimize the development of public transportation nodes. This research aims to determine the use of the type of electric vehicle with the lowest emissions and determine the optimal number of bus terminal mapping, so that it can reduce emissions due to transportation activities and create financial savings in the process of installing solar panels as a means of converting renewable energy sources at each bus terminal in the IKN area. . This research method was carried out by studying a literature review regarding electric vehicles and using the set covering problem method in determining the optimal number of bus terminals, as well as using the interview method to obtain primary data. BEV type electric vehicles are most suitable for use in IKN, because they emit fewer emissions than other types. In creating optimization, there are six bus terminal construction locations that can serve other areas in IKN.
