Abstract

Air Pollution become one of serious issue that must be deal with. One of them is SO2 Pollution. This gas is hazardous even in small concentration and can cause inflammation and irritation on respiratory system. Therefore, it is urgent to made an early detection device that can detect the existence and level of SO2 concentration. This research was successful to find out the performance of TiO2 material for detection SO2 gas. SO2 gas concentration used is 10 ppm. The TiO2 material was synthesized using solvothermal method at 180 C by varying the reaction time. Sensitive material is made above the FTO glass. The Material Characterization indicate the structure of TiO2 is rutile which have round structure that covered by nanorods TiO2. The size of the diameter of nanorods increases with increasing reaction time. Sensor testing was carried out from 150o C – 350°C using 10 ppm SO2. The test results showed that the best sensor response was obtained from samples with a reaction time of 12 hours at working temperature of 350°C.
