520			_aEXECUTIVE SUMMARY: The University of Rizal System Morong Campus encountered a serious issue caused by bats migrating to the attics of campus buildings. The accumulation of bat feces in these areas created air pollution and posed health risks to students, particularly through inhalation of harmful particles from moist bat droppings. To address this, researchers from the College of Industrial Technology major in Electronics Technology, developed a study titled “Development of Sensor-Based Ultraviolet Rays and Piezoelectric Sound as Bat Repellent and Its Effectiveness.” The goal of the study was to test the effectiveness of two devices—Ultraviolet Rays and Piezoelectric Sound—in repelling bats and reducing fecal accumulation. Before the experiment began, the researchers thoroughly tested each component of the devices to ensure proper functionality. The study was conducted over four weeks, with observations made four days a week. Data collection involved two setups: a controlled setup (with the devices in use) and an uncontrolled setup (without the devices). The effectiveness of each device was measured based on the accumulation of bat feces. The results showed that the Ultraviolet Rays device was highly effective in repelling bats. In the controlled setup, it had a mean fecal score of 1.55, compared to 6.45 in the uncontrolled setup. This resulted in a mean difference of 4.9, with a t-statistic of 5.51 and a p-value of 0.001. Since the p-value was less than the 0.05 significance level, it indicated a statistically significant difference. Similarly, the Piezoelectric Sound device also proved effective, with a mean score of 2.15 in the controlled setup and 8.05 in the uncontrolled setup. The mean difference was 5.9, with a t-statistic of 11.7 and a p-value of 0.001, again confirming a significant difference. Both devices were effective in reducing bat activity and fecal accumulation in the Isidro S. Rodriguez building, particularly on the second floor near Room 224. However, the Ultraviolet Rays device outperformed the Piezoelectric Sound device, making it the more effective solution. This study demonstrates the potential of using sensor-based devices to address bat-related health risks on campus. The Ultraviolet device particular offers a promising and particular approach in safer and cleanest environment for every student and staff.
