Good job, looking for ancient ports of ancient history, has never been done by other researchers.

Aceh was once known as an inter-state trade area by sea. At that time the sea became the main line of export and import between countries.

Many Acehnese communities sent abroad by sea, would need a port to receive ships and cargo goods.

Interesting research conducted by @keuudeip, @vannour, @safar01, and @abelpasai sponsored @mapesa. We wait for the result, good luck.[]
