@thesis{thesis, author={Fauzi Muhammad}, title ={Rancang Bangun Sirine Pengusir Monyet Pada JTM 20 KV Berbasis Arduino Uno.}, year={2022}, url={http://eprints.polbeng.ac.id/6604/}, abstract={Medium Voltage Network the 20 KV (JTM) is a medium voltage line that distributes electrical energy from generators or substations to distribution substations. This network is known as a feeder or feeder. The medium voltage network used by PT. PLN is 20 KV supplied to each customer through the medium voltage network and then channeled to the Low Voltage Network (JTR) distribution transformer, then an Arduino UNO R3-based monkey repellent siren was created in an effort to reduce interference caused by the monkey's working system, namely if When the monkey approaches, the ultrasonic sensor HC-SR04 will detect what is blocking or not receiving and reflecting back the wave, then the siren connected using relay channel 1 which converts DC current to AC through Arduino Uno R3 which is output to the mini siren and will sound properly. In this method the Arduino Uno R3 plays an important role in the tool because it is the brain of the tool, in making the tool it must be designed using the Arduino IDE program to set the ultrasonic sensor HC-SR04 and the length of time the siren sounds, with the main components such as the Arduino Uno R3, the sensor ultrasonic HC-SR04, relay channel 1, and mini siren. These components are assembled so that they are connected and connected properly.} }
