The dock is a very important aspect because it is the cheapest with a considerable distance. One type of dock discussed in this thesis is the Jetty dock. Jetty is a type of Dock that is built extending out into the sea with the aim of reducing sedimentation caused by mud carried by ships when the ship is Docked. Trestle is a component of the Jetty Dock that connects between the Jetty and the Border. Trestle has a similarity to the dock, but the trestle building must be simpler, because the trestle is not functioned as a place for mooring ships, loading and unloading. so that trestle dimensions is quite simple. The length of the trestle is 200 meters with a width of 10 meters. In the trestle structure re-planning agreement on SK SNI-T-15-1991- 03, RSNI-T12-2004, SNI-03-2847-2013, SNI 1725-2016, SNI 2833 2016.
