Survey and monitoring of reservoir water capacity are done periodically. One of the methods for measuring reservoir water capacity is the bathymetry survey. The conventional bathymetry method using a manned vessel is a limited option for reservoir survey in shallow water . Hence, survey is done with unmanned surface vehicle (USV) technology. This research aim to carry out study the performance of USV system for batymetric mapping of ITB Jatinangor campus reservoirs and to calculate ITB Jatinangor campus reservoirs water capacity. This research consists of literature study, data acquisition, and data processing. Data acquisition is done with sounding method to acquire position and depth data using USV. After that, transfer of level is done to the reservoir water level in order to define reservoir base elevation in global coordinate system and bar check is done to yield corrected depth of reservoir base. Then, the elevation data undergo spike cleaning, error correction, and interpolation to generate digital terrain model (DTM) and contour lines. From this data, layouting is done to produce bathymetry map and volume calculation is done to determine ITB Jatinangor campus reservoir water capacity. From this research, the bathymetry map for Situ 1 and Situ 2 ITB Jatinangor campus is produced and reservoir water capacity is calculated for Situ 1 and Situ 2 yielding 15.338,349 m3 and 14.609,956 m3 respectively when the spillway is opened. Also, there are results for calculated water capacity when the spillway is closed with value of 18.298,874 m3 and 32.666,745 m3 respectively.
