Abstract

PT Rekayasa Industri merupakan perusahaan jasa yang bergerak dalam bidang rancang bangun industri. Saat ini sedang melakukan pekerjaan untuk proyek EPC 5 Tangki Timbun untuk PT Trans-Pacific Petrochemical Indotama. Pada proyek EPC 5 Tangki Timbun terdapat pembangunan tangki Paraxyelene Storage (PX Storage). Tangki PX Storage merupakan tangki timbun tambahan, di mana cairan Paraxyelene diambil pada tangki Paraxyelene Daily (PX Daily). Tangki PX Daily mendapatkan cairan langsung dari hasil proses kilang. Memindahkan cairan dari PX Daily ke PX Storage diperlukan pompa transfer paraxylene.
Penelitian ini menggunakan metode logika fuzzy untuk kontrol ketinggian cairan pada tangki agar ketinggian cairan lebih sesuai dengan set point. Skenario pengujian memindahkan cairan dari tangki PX Daily ke tangki PX Storage sehinggu memenuhi set point. Set point diatur pada 85% dari ketinggian cairan pada tangki PX Storage. Kondisi awal ketinggian cairan tangki PX Daily yaitu 80% sedangkan kondisi awal ketinggian cairan tangki PX Storage yaitu 60%.
Berdasarkan hasil pengujian yang dilakukan pada implementasi logika fuzzy untuk kontrol ketinggian cairan pada tangki. Pada metode Fuzzy Logic mendapatkan hasil cairan pada tangki PX Storage lebih sesuai dengan set point dibandingkan dengan metode ON-OFF. Hal ini bisa dilihat dari data pada metode ON-OFF %Maximum Overshoot didapatkan 5.3% sedangkan pada metode Fuzzy Logic didapatkan 2.28%. Pada metode Fuzzy Logic lebih lama menuju set point dibandingkan dengan metode ON-OFF. Hal ini dapat dilihat dari nilai Rise Time dengan metode ON-OFF didapatkan waktu 27 detik untuk mencapai set point dan pada metode Fuzzy Logic didapatkan nilai 39 detik untuk mencapai set point.
================================================================================================
PT Rekayasa Industri is a service company engaged in industrial design and is currently working on the EPC 5 Storage Tank project for PT Trans-Pacific Petrochemical Indotama. In the EPC 5 Storage Tank project there is the construction of a Paraxylene Storage (PX Storage) tank. The PX Storage tank is an additional storage tank, where the Paraxylene liquid is taken from the Paraxylene Daily (PX Daily) tank. The PX Daily tank gets its liquid directly from the refinery process. Moving fluids from PX Daily to PX Storage requires a paraxylene transfer pump.
This research uses fuzzy logic method to control the liquid level in the tank so that the liquid level is more in line with the set point. The test scenario moves liquid from the PX Daily tank to the PX Storage tank so that it meets the set point. The set point is set at 85% of the liquid level in the PX Storage tank. The initial condition for the PX Daily tank fluid level is 80%, while the initial condition for the PX Storage tank fluid level is 60%.
Based on the results of tests carried out on the implementation of fuzzy logic for controlling the liquid level in the tank. In the Fuzzy Logic method, the liquid results in the PX Storage tank are more in accordance with the set point compared to the ON-OFF method. This can be seen from the data in the ON-OFF %Maximum Overshoot method, which is 5.3%, while the Fuzzy Logic method is 2.28%. The Fuzzy Logic method takes longer to reach the set point than the ON-OFF method. This can be seen from the Rise Time value with the ON-OFF method, it takes 27 seconds to reach the Set Point and the Fuzzy Logic method gets a value of 39 seconds to reach the Set Point.
