<![CDATA[Indonesia, as an archipelagic country with over 17,000 islands, faces significant challenges in providing electricity access, particularly to small and remote islands. One promising solution is Solar Power Plants (PLTS), both land-based and floating solar plants that utilize water surfaces, suitable for areas with limited land availability. This study evaluates the economic feasibility of floating solar plants and land-based solar plants using the Levelized Cost of Electricity (LCoE) approach. LCoE encompasses all costs of construction, operation, maintenance, and energy production over the plant's lifespan, serving as a key benchmark in selecting power generation technologies. The findings show that the LCoE for floating solar plants is Rp11,197.00/kWh, lower than land-based solar plants at Rp11,769.00/kWh, although both exceed the electricity purchase price in Kodingareng, South Sulawesi, at Rp2,460.00/kWh. This difference is influenced by higher construction costs for floating solar plants but offset by greater energy output and lower operation and maintenance costs. This research provides a basis for developing solar power systems in archipelagic regions, emphasizing efficiency and sustainable energy solutions.]]>
