Abstract

Produk minyak bumi digunakan secara luas dalam kehidupan sehari-hari, dari bahan bakar hingga produk kimia. Salah satu aspek penting dalam pengolahan dan distribusi minyak bumi adalah pour point, yaitu suhu terendah di mana fraksi minyak bumi masih dapat mengalir. Penentuan pour point ini krusial untuk efisiensi operasional, terutama dalam pemindahan dan transportasi minyak. Penelitian ini bertujuan untuk mempercepat proses pengujian pour point dengan mengimplementasikan prototype pengujian pour point menggunakan metode PID. Parameter kontrol PID disesuaikan menggunakan Metode Ziegler-Nichols untuk mendapatkan kinerja optimal. Pengujian sistem melibatkan seluruh bagian sistem untuk proses pendinginan dan tuning PID untuk mencapai suhu target. Dengan menggunakan Metode Ziegler-Nichols Closed Loop, didapatkan nilai Kp=0,6, Ki=1, dan Kd=0,09. Hasil penelitian menunjukkan bahwa sistem pengujian pour point dapat beroperasi tanpa overshoot dengan tuning lanjutan nilai Kp=0,4, Ki=0,09, dan Kd=0,02. Sistem mencapai nilai setpoin dengan rise time sebesar 92 detik dan mampu menguji sampel 'Turbo Lube 220' dengan hasil pour point -9°C. Temuan ini menunjukkan bahwa dengan tuning lanjutan, sistem kontrol PID dapat meningkatkan efisiensi dan keakuratan pengujian pour point, memberikan hasil yang lebih andal dan operasional yang lebih efisien dalam industri minyak bumi.

Petroleum products are widely used in everyday life, from fuels to chemical products. One crucial aspect of petroleum processing and distribution is the pour point, which is the lowest temperature at which a fraction of petroleum can still flow. Determining the pour point is vital for operational efficiency, particularly in the transfer and transportation of oil. This research aims to expedite the pour point testing process by implementing a pour point testing prototype using the PID method. The PID control parameters were adjusted using the Ziegler-Nichols Method to achieve optimal performance. System testing involved all parts of the system for the cooling process and PID tuning to reach the target temperature. Using the Ziegler-Nichols Closed Loop Method, the values obtained were Kp=0.6, Ki=1, and Kd=0.09. The results showed that the pour point testing system could operate without overshoot by tuning the values to Kp=0.4, Ki=0.09, and Kd=0.02. The system reached the setpoint with a rise time of 92 seconds and was able to test the 'Turbo Lube 220' sample with a pour point result of -9°C. These findings indicate that with tuning, the PID control system can enhance the efficiency and accuracy of pour point testing, providing more reliable results and more efficient operations in the petroleum industry.
