A Dissolved oxygen (DO) sensor has been designed and fabricated on an 85 x 205 mm galvanic-based. The sensor structure device consists of Al-Zn reference layer electrode, Ag/AgCl active electrode, 120ml KCl electrolyte solvent 0,1 M, and closed by TiO 2 membrane (PTFE). The Al-Zn formation reference electrode was done by Ag layer chlorination using FeCl 3 , and the TiO 2 membrane was formed by TiO 2 paste screen printing. The test was done to measure the sensor’s performance based on the current-voltage characteristics between 1.0 and 1.8 V. The results showed that a stable diffusion current was obtained when the input voltage was 1.5 V, resulting in the best sensor performance with a sensitivity of 0.7866 μA L/mg and a stable step response time of 3 mins. This prototype sensor showed high potential for prototyping for a low-cost water quality monitoring system.}, issn = {2338-0403}, pages = {83--89} doi = {10.14710/jtsiskom.2021.13996}, url = {https://jtsiskom.undip.ac.id/article/view/13996} }
