Abstract

Salah satu masalah yang sering terjadi di dunia industri adalah pengaturan kecepatan motor pada sistem pencampuran, khususnya pada tangki agitator. Perubahan kekentalan akibat proses pencampuran bahan yang semakin menyatu dan merekat dapat menyebabkan beban kerja motor berubah, sehingga memengaruhi kestabilan putaran motor. Penelitian ini bertujuan untuk mengatur kecepatan motor agar tetap stabil saat terjadi gangguan akibat perubahan beban dari cairan PVA (Polyvinyl Alcohol), serta memastikan motor tetap berjalan sesuai kecepatan yang diinginkan. Solusi yang digunakan adalah mengatur kecepatan motor dengan penyesuaian berdasarkan kebutuhan proses di dalam tangki, menggunakan pengendali PID untuk menjaga kestabilan kerja motor. Sistem ini dirancang dalam bentuk prototipe, disimulasikan menggunakan perangkat lunak MATLAB, dan telah diuji pada sistem sebenarnya. Nilai pengaturan PID terbaik yang diperoleh adalah Kp = 0.2602, Ki = 0.064061, dan Kd = 0.63888. Dari hasil pengujian, sistem menghasilkan lonjakan (Overshoot) sebesar ±2%, waktu mencapai kondisi stabil (Settling Time) sekitar ±5 detik, dan waktu naik (Rise Time) sekitar ±4 detik. Hasil ini menunjukkan bahwa pengendali PID mampu menjaga kestabilan kecepatan motor dan membantu kelancaran proses pencampuran di dalam tangki.

One common issue in the industrial sector is the regulation of motor speed in mixing systems, particularly in agitator tanks. Changes in viscosity due to the mixing process, where materials gradually blend and thicken, can lead to variations in motor load, thus affecting the stability of motor rotation. This study aims to maintain a stable motor speed in the presence of disturbances caused by load variations from Polyvinyl Alcohol (PVA) fluid, ensuring the motor continues to operate at the desired speed. The proposed solution involves adjusting the motor speed based on the process requirements within the tank, utilizing a PID controller to maintain motor performance stability. The system was developed as a prototype, simulated using MATLAB software, and tested on an actual setup. The optimal PID tuning values obtained were Kp = 0.2602, Ki = 0.064061, and Kd = 0.63888. The test results showed an Overshoot of approximately ±2%, a Settling Time of about ±5 seconds, and a Rise Time of around ±4 seconds. These results indicate that the PID controller effectively maintains motor speed stability and supports the smooth operation of the mixing process within the tank.
