THE SEA DEPTH CONTROL AND MONITORING SYSTEM ON SHIP PROTOTYPE

Abstract

With Indonesia's very geographical position, it does not rule out the possibility that the conditions of the docks at the Indonesian Navy bases have varying depths depending on the tides and contours of the underwater land. Changes in the contour of underwater land in several regions of Indonesia are rapidly changing due to several reasons, for example earthquakes, climate change, changes in current patterns, sedimentation, global warming and so on. A safe and efficient berthing process is the key to carrying out the KRI's main tasks. The success of this berthing process depends not only on the skills of the ship's crew, but also on a deep understanding of the depth of the sea around the pier. A vehicle or tool is needed to help measure sea depth, especially around the pier, which can be monitored directly with a control system. The method used is a qualitative descriptive approach through trial and error techniques. By carrying out various kinds of experiments and measurements on components and analyzing the results in accordance with the applied theory. The control system uses two push buttons, a joystick, and a potentiometer with Arduino Nano and Uno and the NRF24L01 module shows the reliability of wireless communication at the 2.4 GHz frequency with a range of 90.32 meters in an open environment. Ocean depth monitoring using the NRF24L01 module on the same frequency succeeded in receiving data on depth, position, angle of inclination of the ship, and time per two to three seconds with the same range. Data can be monitored in Excel or graphic format using PLX-DAQ software.
