PEMETAAN BATIMETRI UNTUK PENENTUAN UJUNG DERMAGA DAN POSISI TIANG PANCANG PADA RENCANA DERMAGA PLTMG SELAYAR

This research aims to obtain the position of the front line of the jetty and obtain the coordinate position of thepile caps.The jetty front line is determined based on the characteristics of the ship design. The jetty plan is plotted on abathymetric map made to determine the coordinate position of the pile caps. The jetty front line is located at a depth of -5.4 meters LWS. Jetty construction is supported by 54 pile caps consisting of 14 pile caps for single pile at the front ofthe jetty, 2 pile caps for single pile and 12 pile caps for double pile in the middle of the jetty, 14 pile caps for a single pileat the back of the jetty. The position of the pile cap is defined as X, Y coordinates based on the Universal TransverMercator coordinate system, with the ellipsoidal WGS 84 datum
