Abstract
Kerusakan pada motor induksi 3 fasa pada mesin kompresor di PT Indolakto Factory Pandaan umumnya disebabkan oleh gangguan thermal dan arus lebih yang bermula dari masalah internal motor induksi. Seperti kumparan motor yang sudah mulai rusak, gearbox atau bearing yang sendat, dan kipas pendingin yang tidak berfungsi. Proyek Akhir ini bertujuan untuk mengatasi permasalahan tersebut dengan merancang Sistem Proteksi Gangguan Thermal dan Arus Lebih Motor Induksi 3 Fasa pada Mesin Kompresosr Menggunakan Metode Logika Fuzzy. Proyek Akhir ini juga bertujuan untuk aplikasi fitur mobile app untuk monitoring nilai temperatur dan arus pada motor induksi serta dapat memutus daya motor induksi 3 fasa secara online. Prinsip kerja sistem proteksi ini yaitu ketika kendali logika fuzzy menetapkan motor induksi dalam kondisi peringatan maka sistem secara otomatis mengirimkan peringatan berupa notifikasi kepada pengguna. Begitu juga ketika temperatur dan arus terdeteksi melampaui nilai nominal maka motor trip. Dari hasil pembacaan temperatur oleh sensor DS18B20 dan termometer digital, terdapat rata-rata error sebesar 0,64%. Hasil pembacaan arus oleh sensor ACS712 dan amperemeter, terdapat ratarata error sebesar < 1%. Pengujian dilakukan terhadap motor induksi 3 fasa berdaya 0,3 HP. Dengan hasil pengujian ketika didapatkan pembacaan arus motor sebesar 0,51; 0,53; dan 0,52 A kontrol logika fuzzy menentukan motor dalam kondisi peringatan. Sementara kontrol logika fuzzy menentukan motor dalam kondisi gangguan ketika didapatkan pembacaan arus motor sebesar 0,68; 0,69; dan 0,67 A.

The failure of the 3-phase induction motor on the compressor at PT Indolakto Factory Pandaan is generally caused by thermal and overcurrent that is starting with internal problems of the induction motor. Such as motor coils that have started to break, gearbox or bearings that are clogged, and cooling fans that don't work. This final project aims to overcome these problems by designing a Protection System of 3-Phase Induction Motor Thermal and Overcurrent Fault on Compressor Machines Using Fuzzy Logic Method. This final project also aims for the application of mobile app features for monitoring the temperature and current values in induction motors and being able to disconnect the power of 3-phase induction motors online. The working principle of this protection system is that when fuzzy logic control sets the induction motor in a warning condition, the system automatically sends a warning in the form of a notification to the user. Likewise, when the temperature and current detected exceed the nominal value, the motor trips. From the results of temperature readings by the DS18B20 sensor and digital thermometer, there is an average error of 0.64%. The results of current readings by the ACS712 sensor and ammeter, there is an average error of < 1%. The test was carried out on a 3-phase induction motor with a power of 0,3 HP. With the test results when the motor current readings are obtained by 0,51; 0,53; and 0,52 A fuzzy logic control determines the motor is in a warning state. Meanwhile, fuzzy logic control determines that the motor is in a fault condition when the motor current reading is 0,68; 0,69; and 0,67 A.
