Description

My goal in doing this project is to see how much silting has occurred in Lake Rawapening, Central Java, Indonesia, with the hope that in the future the Indonesian government can make improvements so that the lake will return to being beautiful and not shrinking. This tool uses a standard NMEA gps module and a standard NMEA SONAR module, plus an SD card to accommodate data. The way this tool works is by taking gps data from the NMEA protocol gps module and then retrieving water depth data using the SONAR module with the NMEA protocol and then storing it on the sdcard module. this tool uses an input voltage of 12 VDC can use the battery inside the tool using step up to turn on SONAR, Step down 5 V is used to turn on LCD OLED, Arduino MEGA MINI, GPS, SD Card Module. The data obtained in the form of GPS coordinates and water depth, from this data can be described on a map how deep the water is in the lake, then a few months later data is taken again to see which parts have changed and what causes it so that it can suggest to the government what actions to take. needed to anticipate lake silting. In the planning of this tool, the first version is using gps and sonar using fishing boats to retrieve data, by rotating the lake and then zigzagging along the lake. it is hoped that the second version will be able to make a remote control of the ship that can operate alone or with a remote control, the purpose of the second version is that the device can retrieve its own data with the ship's remote control via predetermined gps coordinates so that the data taken will be more measured and neatly arranged, and this organized data can be used as a comparison for further data. After getting the data that we need, the next step is to interpret the data into a google map so that a visualization can appear that shows the depth per meter in the lake. The cause of silting can be from plastic waste carried by rivers leading to lakes or mud carried from rivers or wild plants such as water hyacinth that accumulate so that it becomes silting. If this siltation is not corrected, it will result in the loss of water sources and threaten agriculture.
