Abstract

Eastern Indonesia is a very beautiful area that is supported by biodiversity and the development of the industry that is currently being developed. Eastern Indonesia has one of the Luwuk waters, with locations (0°50'37.5" S, 123°05'38.0" E) in Banggai Regency. Indonesia has become a place for the construction of many public ports and private ports. This requires study activities to find out the depth of the sea using underwater acoustic technology with a multibeam echosounder so that it can accurately find out the depth of the sea in these waters. A multibeam echosounder can produce data density information and high-resolution digital surface models. This result is supported by the correction of positions using a DGPS (Differential Global Positioning Systems) system with satellite correction and survey calibration using a patch test (the value correction is 2.4°, 3.2°, and -4.55°). The results of the depth value were generated by making corrections using tidal data and sound speed data. The tidal datum we use is mean sea level, and the tidal type is mixed tide, with dominated semi-diurnal. The calculated average depth is between 10 m to 13 m, the calculated minimum depth is 0.90 m, and the calculated maximum depth value is 27.72 m.
