Looks like so, that design (90 m) haven't been present on Citra Shipyard website (they only showed the 80 m one). But its appearance on Pinhantanas might meant that it's their own design.

The left-middle is made by PT Citra Shipyard: https://en.pinhantanas.com/category/ships#

350 m + WOODEN ship before 1800s is INDEED myth, no wood is strong enough to make ship such large.
In fact, above certain size (about 300 ft or 91 m) a wooden ship would be considered structurally unsafe. Only after 1800s and iron used for frame and hull, a ship can finally reach more than that...
