Since I'm an Indonesian, I was kind of insulted with this manga even though it is said that it's the culture of Urunei Kingdom but from the Language to the Coins that are thrown in this chapter is identical to Indonesians

No, it's certainly Indonesia because the shape of the coin currency they are using are identical as Indonesian coin which has Garuda Bird in it and even the princess name is putri harimau which means tiger princess in indonesia and also the place where they use a boat to see the people it's identical with the floating Markets that are in Kalimantan/Borneo
