Rice yields in several areas have decreased, which is felt by Mudiyono, a Sido Rukun Farmers Group member in Padangan Hamlet, Ponjong District, Gunungkidul Yogyakarta. According to Mudiyono, the decrease in income was caused by bird attacks that eat rice grains 5 grams a day on average.

The methods practiced to repel bird pests by farmers have been limited to the use of nets and people in the fields. However, this method is considered ineffective and efficient because it requires a lot of maintenance time and a very varied attack of bird pests.

Based on the problems faced by Mudiyono, UNY students through the Science and Technology Application Student Creativity Program (PKM-PI) team made a bird repellent device called the "Peksi Repellent Machine." The students are Leni Widyastuti (Biology), Nur Intan Permatasari (Biology), Anggoro Fajar Dwi U (Mechatronic Engineering Education), Abdul Rosyid Hidayatullah (Physics), Hidayati Nur Hakimah (Economics Education) with a companion lecturer Ariadie Chandra Nugraha, MT.

Leni Widyastuti explained, the word Peksi comes from the Javanese language, which means bird. So the Peksi Repellent Machine is indeed made to repel bird pests. "In the design tool, we pay attention to the existing science, taking into account the range of the instrument, the range of the sensor, and the range of the speaker. It also takes into account the power of the device."

"If the device is turned on using the application, then the tool can detect birds using the RCWL sensor. This sensor is a microwave motion sensor that can detect the presence of birds by sending microwaves. This sensor detects the presence of birds using bird movements which can change the signal received by this sensor," Leni continued.

Furthermore, added Leni, the device will emit an ultrasonic sound. Besides that, when the tool detects a bird, it will report a notification to Telegram.

"We made a manual to make it easier to operate so that farmers can easily operate the tool," he explained. (Witono, ts-Arfian, Alina)
