UB Teach Residents to Assemble Bats Repellent Device
Still in community service activities, lecturers and students of Electrical Engineering, Faculty of Engineering, Universitas Brawijaya (FT-UB) provide training on assembly of solar cells and electronic devices to representatives of youth organizations karang taruna and remaja masjid, and residents in the neighborhood of Al-Ghozali, Tlogomas, Lowokwaru District, Malang.

“Initially we offered a training on solar cells and electronic devices supporter assembly, but they also confide that they need a solutions to overcome the bats disruption in the mosque neighborhood. Finally, we also provide a training on making electronic bat repellent devices,” said the lecturer in charge of activities, Eka Maulana, ST. , MT., M.Eng.

The training was attended by 30 participants took place on 30-31 July 2016. In addition to Eka, the students involved were Hasan Albinsaid, Dony Darmawan Putra, Muhammad Fatahillah, Amrizal Karim Amrulloh, Muhammad Ilham Akbar, Muslichin, Mahfudz, and Muhammad Arsil Khaji.

Eka said, the working principle of the device is quiet simple. Using ultrasonic frequencies emitted by the transducer to disrupt bats communication and navigation systems.

“In principle all living things humans, plants, or bacteria are sensitive to certain frequency,” the alumni of University of Miyazaki Japan said.

The frequency can be generated at a specific value depend on its function, for communication or interaction between living things such as calling, expel, or even to help their growth. Meanwhile, bats emit ultrasonic waves with a frequency of 30-50 kHz for communication and navigation systems.

“Through the signals on certain frequencies emitted by electronic devices, bats will get annoyed and will hopefully go away and do not make trouble,” he explained.

Eka likens, humans may also be disrupted and upset when heard the high frequency signal.

Bat repellent device assembly process also does not take a long time. It’s just for the general public they still need time to learn programming and make the microcontroller component.

The microcontroller components is used to generate and simultaneously measuring the frequency produced by the device. The programming language used is C.

At bat repellent device installed at the Al-Ghozali, their energy sources are generated using solar cells with an output power of 50 Watt. Solar cell is connected to the solar regulator controller, to be then stored in the battery and supplying device.

“The initial target of the solar cell is used only to support the bat repellent device. But in the future is expected to be used for power backup of mosque electronic devices such as amplifiers (loudspeakers) and lamps for lighting,” added the Blitar born lecturer.

Manufacture of repellent bat at Masjid Al-Ghozali cost approximately Rp. 100.000,- excluding the battery and solar cell components. So far the device can cover 5-10 meter area. Eka claimed ready to provide similar training in other places where it is needed by the community.

Meanwhile, the board of Al-Ghozali mosque, Erfan, said that the bat in his area is disturbing the cleanliness of the mosque through its manure produced. So this training is very helpful to maintain the cleanliness of the mosque as well as adding practical skills, especially in electricity.

"The last reports from the takmir, since the device is installed there is no more bats that go into the mosque,” he said. (and/Humas UB)
