Pasak 01 is a self‑propelled hopper barge built in 2010 by Panah Sakti Shipyard, Indonesia. Displacing 1,405 GT with a 1,300 m³ hopper, it measures 70.8 m×12.8 m×4.98 m and is driven by twin 400 HP Yuchai engines, achieving a service speed of 5 knots. The barge has been deployed in key dredging operations—most recently at Tanjung Perak Port in 2023—and is prized for its capacity, reliability, and essential role in maintaining Indonesia’s navigable waterways.
