STUDI PERENCANAAN SISTEM FENDER DERMAGA (JETTY) DI PELABUHAN TANJUNG TEMBAGA 1 KOTA PROBOLINGGO

Abstract

The Port of Tanjung Tembaga, East Java is a port that is certain to become a multipurpose port in serving
various types of loading and unloading of goods. The effort was carried out by the East Java provincial
government by building a new jetty that will serve ships with a capacity between of 15000-20000 DWT.
One of the main points in jetty structure planning is safety, which is called fender. The purpose of this study
is to plan a fender system that is integrated with the jetty structure.
The method of this study is to collect data on ships, wind, currents, bathymetry, waves, and tides that will
be classified for fender system planning and jetty structure.
In this study, it was concluded that the impact energy of the ship that occurred was 689.3kN. So it is planned
that the SCN-800 F.2.5 fender type with a 3x1m frontal pad has an absorption energy of 308.6 kN / fender.
In the structural design the dimensions of the floor plate t = 320 mm, 1200x850mm elongated beam,
1200x900mm crane beam, 1200x800mm transverse beam, 1200x850mm diagonal beam, 1200x750mm
edge beam, 5000x3000x1200mm fender beam and 5000x3000x1100mm. the pile cap obtained dimensions
3400x1800x2000 mm, 3600x1800x2000mm, 1800x1800x1800mm, 1800x1700x2000mm, and
2200x2200x2000mm. The foundation used is 1016mm steel pipe pile with a depth of 18.45m-seabad
(vertical pile), 21.45m-seabad (diagonal pile). As well as a planned concrete filler (virtual column) with a
diameter of 978mm with a length of 3m.
