National Maritime Day is observed in Indonesia every September 23. Established in 1964 by President Sukarno, the day commemorates the country's first Maritime Conference held in 1963. Given Indonesia's status as the world's largest island country, with over 17,000 islands, the maritime sector is crucial for its economy, society, and national security. Sea transport plays a vital role in economic integration and trade, with significant ports on each major island. Despite the importance of the maritime sector, challenges such as high logistics costs and illegal fishing persist. Various maritime organizations, including the Indonesian Maritime Youth Association, organize events to promote the sector's development and address its challenges. However, the holiday is not widely celebrated, as the current government has not reaffirmed its significance.
