Analisis Pengukuran Batimetri dan Pasang Surut untuk Menentukan Kedalaman Kolam Pelabuhan ( Studi Kasus: Pelabuhan Tanjung Perak, Surabaya)

摘要

Port of Tanjung Perak port is one of the gates in Indonesia, which became the center of the distributor of goods to eastern Indonesia, especially to the province of East Java. The development of trade and increasing traffic flow then made efforts to develop transportation facilities, especially with regard to the safety of navigation of the ship. In this case analysis bathymetry measurements and observations in the tidal waters of the port of Tanjung Perak port to determine the depth of the pool on a regular basis. Tidal data for 29 piantan analyzed by methods admiralty and port pool depth measurement is determined based on the draft (laden ship) ships planned maximum. These data will be combined gross weight to freedom space for 7% of maximum draft, as the port of Tanjung Perak designed sheltered from the waves. Consider the oscillatory motion with the ship because environmental influences such as waves, wind, and tides; port pool depth is 1.1 times the full load draft of the ship below the water table elevation plans. Bottom waters of each pool Tanjung Perak harbor, have morphologies average flat to almost flat (flat / nearly flat) with values ranging from 1.278 to 1.547% slope and has a depth of 2.980 to 20.06 m. While the type of tidal waters of Tanjung Perak port is a single daily tidal (diurnal tide); with the datum value obtained as follows: 1.68 m MSL, LLWL -0.22 m, 3.58 m HHWL, and Z0 by a margin of 1.33 m lau face highs and lows of 2.46 m. Water pools on 5 shared port with the appropriate port built design an insulated tilt against the waves. Each port pool depth I, II, III, IV, and V are required in a row is at 7.5589 m; 6.5638 to 7.5589 m; 9.5063 m; 8.0511 m; and from 6.5638 to 8.5326 m with a maximum boat weight mold was determined from the PT. PELINDO to operate in every port pool.Then based on bathymetric data has been corrected tidal for port pool I that is between 3.830 to 7.5 m; should be dredging. For the port pool II bathymetric data between 2.220 to 6.5 m; should be dredging. For the port pool III between 1.260 to 9.5 m should be dredging. In depth data for port pool IV be between 1.26 to 8 m should be dredging. The last for port pool V between 3.78 to 6.5 m should be dredging.
