Abstract

PT PG Rajawali I, khususnya di PT PG Krebet Baru, bergerak dalam industri gula dengan proses bisnis yang meliputi ekstraksi, klarifikasi, evaporasi, kristalisasi, dan sentrifugasi. Stasiun penggilingan memegang peranan kritis dalam proses ini, di mana motor listrik menggerakkan cane carrier untuk mengangkut tebu. Namun, sering terjadi penumpukan tebu pada chute atau saluran tebu akibat ketidaksesuaian kecepatan motor dengan aliran material. Untuk mengatasi masalah ini, penelitian ini bertujuan mengimplementasikan kontrol PID guna mengatur kecepatan motor cane carrier secara otomatis berdasarkan ketinggian ampas tebu di chute. Metode penelitian meliputi perancangan sistem kontrol berbasis Arduino Uno yang terintegrasi dengan sensor proximity untuk memantau ketinggian ampas tebu dan VFD ATV12HU15M2 sebagai pengatur kecepatan motor induksi tiga fasa. Parameter PID ditentukan menggunakan metode Ziegler-Nichols kedua, dengan nilai Kp = 60, Ki = 1,168, dan Kd =770,82, dengan nilai overshoot 25% dan rise time 37 detik. Pengujian sistem cane carrier menggunakan kontrol PID menunjukkan bahwa penerapan sistem kontrol PID pada pengaturan kecepatan motor cane carrier berdasarkan ketinggian ampas tebu telah berhasil meminimalisir permasalahan penumpukan tebu pada chute. Hal ini dikarenakan oleh nilai error yang masih kecil, yaitu 0,89. Sistem menghasilkan nilai PWM rata-rata sebesar 142,39. Pada saat pengujian, nilai level pada chute menunjukkan di angka 5 selama 13 detik dari 219 detik, sehingga penumpukan tebu telah diminimalisir.

PT PG Rajawali I, particularly at PT PG Krebet Baru, operates in the sugar industry with business processes including extraction, clarification, evaporation, crystallization, and centrifugation. The milling station plays a critical role in this process, where an electric motor drives the cane carrier to transport sugarcane. However, frequent sugarcane pileups occur in the chute due to mismatched motor speed and material flow. To address this issue, this study aims to implement PID control to automatically regulate the speed of the cane carrier motor based on the sugarcane level in the chute. The research method involves designing a control system based on Arduino Uno, integrated with infrared proximity sensors to monitor sugarcane levels and an ATV12HU15M2 Variable Frequency Drive (VFD) to adjust the speed of a three-phase induction motor. PID parameters were determined using the second Ziegler-Nichols method, with values of Kp = 60, Ki = 1,168, and Kd = 770,82, with an overshoot of 25% and a rise time of 37 seconds. Testing of the cane carrier system with PID control demonstrated its effectiveness in minimizing sugarcane pileups in the chute. This is attributed to the system’s small steady-state error (0.89) and an average PWM output of 142.39. During trials, the chute level remains at 5 for only 13 seconds out of 219 seconds of operation, confirming significant mitigation of the issue. The results validate that the PID-controlled system successfully optimizes motor speed regulation in response to real-time sugarcane level variations.
