Abstract

Water quality in milkfish cultivation requires great attention. Factors such as salt content in water, temperature, and pH become parameters to determine water quality. Salinity levels determine growth in pond aquatic ecosystems. This change is due to the biological processes in these waters and the interaction between the waters where milkfish are cultivated and the surrounding environment. This condition can be minimized, one of which is using regular observations of water quality in the cultivation area so that a monitoring tool is needed that can continuously maintain water salinity levels in the milkfish culture. Monitoring can use a salinity sensor to indicate the salinity level of the water used in milkfish cultivation. The results of the calibration of the salinity sensor of the first test, namely on 100mL of Aquades water, obtained an error of 0%, the second test was on 100mL of seawater with an error of 4.17%, and finally, the third test was a test of mixing 50mL of Aquades water and 50mL of seawater with an error of 4.04%. According to the calculation, the freshwater content required for comparing sea water and freshwater is 3.3 L. The testing is for 15 min and is carried out from 09.00 to 10.00, from noon 13.00 to 14.00, and in the afternoon from 16.00 to 17.00. The test results in the morning of 18.92 ppt. During the day, the salinity value is 15.78 ppt. In the afternoon, the salinity value was 15.57 ppt, but the salinity value obtained had not yet reached the set point of 15 ppt.
