Dredging is one of the seaport's regular and necessary maintenance activities to keep the sea depth under control. The purpose of dredging is to provide safe navigation where the depth of the water column must be more profound than the ship's draft. Periodic bathymetric surveys using an echosounder can observe changes in the topography of the seabed. Topographic changes over time can be used to calculate the volume of sedimentation. Triangular Irregular Network (TIN) is one of the methods to calculate cut and fill volume in some software. This study aims to compare the difference in the sediment volume calculation results from interpolation data with EIVA and CAD. This study uses data from Multibeam Echosounder, carried out before dredging (mc0) and after dredging (mc100). This study shows the difference in volume calculation because of dredging is 693, 228.00 m3 using CAD and 701, 700.633 m3 using EIVA. Statistic test for volume calculation from this software using a p-value of Friedman test shows no significant difference between these two software calculations.
