Abstract

Pengisian cairan hidrogen peroksida (H2O2) 50 % di sektor industri menuntut presisi tinggi karena deviasi volume tidak hanya memicu pemborosan bahan baku, tetapi juga berisiko menurunkan konsentrasi efektif, memengaruhi kualitas produk, serta melanggar standar keselamatan kerja dan regulasi lingkungan. Praktik manual yang masih mengandalkan pengamatan visual operator sering menimbulkan ketidakkonsistenan volume, laju kerja lambat, dan ketergantungan pada keterampilan individu. Seiring adopsi konsep Industry 4.0, diperlukan solusi otomasi terukur yang mampu menjaga akurasi pengisian, mengurangi kontak langsung pekerja dengan zat kimia reaktif, dan memaksimalkan efektivitas lini produksi. Penelitian ini merancang dan mengimplementasikan sistem pengisian berbasis kendali PI (Proportional– Integral) dengan parameter Kp = 2,8656 dan Ki = 6,66 untuk mempertahankan volume sesuai target secara konsisten. Sistem memanfaatkan sensor flow meter Aichi OF05ZAT guna memantau aliran cairan secara kontinu, sementara motor stepper Vexta NEMA 23 mengatur bukaan globe valve secara bertahap. Mikrokontroler Arduino Mega 2560 memproses data sensor dan menjalankan algoritma PI untuk mengoreksi selisih antara volume aktual dan set point, sedangkan HMI Nextion menyediakan antarmuka pemantauan dan pengaturan parameter proses. Pengujian dilakukan pada tiga setpoint volume yang berbeda, yaitu 10, 15, dan 25 liter. Hasil pengujian menunjukkan bahwa sistem kontrol PI berhasil mencapai target dengan tingkat presisi yang sangat tinggi. setpoint 10 liter, sistem mencapai overshoot sebesar 0.90% dengan steady state error -0.09 L. Untuk setpoint 15 liter, overshoot yang dihasilkan adalah 0.27% dengan steady state error -0.04 L. Sementara pada setpoint 25 liter, sistem mencatatkan overshoot terendah sebesar 0.16% dengan steady state error -0.04 L. Rata-rata overshoot dari ketiga pengujian tersebut hanya 0.44%, sebuah peningkatan signifikan dibandingkan dengan sistem open loop. Hasil ini membuktikan bahwa implementasi kontrol PI mampu mengendalikan laju aliran secara efektif, menghasilkan proses pengisian yang akurat, stabil, dan dapat diandalkan untuk aplikasi industri.

The industrial filling process of 50% hydrogen peroxide (H₂O₂) demands high precision, as volume deviation not only leads to raw material waste but also risks reducing the effective concentration, affecting product quality, and violating occupational safety and environmental regulations. Manual practices, which still rely on visual observation by operators, often result in inconsistent volumes, slow work rates, and dependency on individual skills. With the adoption of Industry 4.0 concepts, a measurable automation solution is needed to maintain filling accuracy, reduce direct worker contact with reactive chemicals, and maximize production line effectiveness. This research designs and implements an automatic filling system based on a Proportional-Integral (PI) controller with parameters Kp = 2.8656 and Ki = 6.66 to consistently maintain the dispensed volume according to the target. The system utilizes an Aichi OF05ZAT flow meter sensor to continuously monitor the liquid flow, while a Vexta NEMA 23 stepper motor gradually adjusts the opening of a globe valve. An Arduino Mega 2560 microcontroller processes the sensor data and executes the PI algorithm to correct the difference between the actual volume and the setpoint, while a Nextion HMI provides an interface for monitoring and adjusting process parameters. Testing was conducted at three different volume setpoints: 10, 15, and 25 liters. The test results show that the PI control system successfully reached the targets with a high degree of precision. At the 10-liter setpoint, the system achieved an overshoot of 0.90% with a steady-state error of -0.09 L. For the 15-liter setpoint, the resulting overshoot was 0.27% with a steady-state error of -0.04 L. Meanwhile, at the 25-liter setpoint, the system recorded the lowest overshoot of 0.16% with a steady-state error of -0.04 L. The average overshoot from the three tests was only 0.44%, a significant improvement compared to the open-loop system. These results demonstrate that the implementation of PI control can effectively regulate the flow rate, resulting in an accurate, stable, and reliable filling process for industrial applications.
