Abstract

Penelitian ini berhasil merancang dan membangun simulator custody transfer skala laboratorium yang ditunjukkan oleh nilai linearitas kalibrasi hingga R² = 0,9998, error pengukuran volume rata-rata di bawah 3%, serta kemampuan sistem menghentikan aliran secara otomatis tanpa overshoot signifikan. Sistem ini mengatasi keterbatasan peralatan pendidikan dengan mereplikasi prinsip pengukuran dan pengendalian volume fluida dalam transaksi komersial secara sederhana dan terjangkau. Komponen utama meliputi sensor flowmeter turbin YF-B10-S yang menghasilkan sinyal pulsa proporsional dengan laju aliran, mikrokontroler Arduino Uno sebagai pengendali utama yang memproses pulsa dan menjalankan logika kontrol on-off, pompa satu fasa untuk menggerakkan fluida dari tangki penampung, serta solenoid valve yang secara otomatis membuka/menutup aliran saat volume target tercapai. Proses kalibrasi menunjukkan hubungan linear sangat baik antara jumlah pulsa sensor dan volume fluida aktual, dengan nilai R² mencapai hingga 0,9998 pada berbagai pengujian. Akurasi pengukuran volume secara keseluruhan memiliki error rata-rata di bawah 3% pada bukaan globe valve 80–100% yang menghasilkan laju aliran stabil dan turbulensi minimal, sedangkan pada bukaan di bawah 80% sistem tetap beroperasi namun akurasi menurun akibat meningkatnya fluktuasi laju aliran dan turbulensi yang memengaruhi kestabilan sinyal pulsa flowmeter. Meskipun belum mencapai target akurasi error ±0,5% sesuai standar industri API MPMS Chapter 5 (karena keterbatasan komponen murah dan skala laboratorium), simulator ini terbukti andal dan responsif yang ditunjukkan oleh konsistensi hasil pengukuran, nilai linearitas tinggi (R² hingga 0,9998), serta kemampuan sistem menghentikan aliran secara otomatis pada volume setpoint dengan overshoot volume akhir kurang dari ±1%.

This research successfully designed and built a laboratory-scale custody transfer simulator demonstrated by calibration linearity values up to R² = 0.9998, an average volume measurement error below 3%, and the system's ability to stop the flow automatically without significant overshoot. This system overcomes the limitations of educational equipment by replicating the principle of measuring and controlling fluid volume in commercial transactions in a simple and affordable manner. The main components include a YF-B10-S turbine flowmeter sensor that produces a pulse signal proportional to the flow rate, an Arduino Uno microcontroller as the main controller that processes the pulse and runs the on-off control logic, a single-phase pump to move fluid from the storage tank, and a solenoid valve that automatically opens/closes the flow when the target volume is reached. The calibration process shows a very good linear relationship between the number of sensor pulses and the actual fluid volume, with R² values reaching up to 0.9998 in various tests. The overall volume measurement accuracy has an average error below 3% at 80–100% globe valve opening, which results in a stable flow rate and minimal turbulence, while at openings below 80% the system remains operational but accuracy decreases due to increased flow rate fluctuations and turbulence that affect the stability of the flowmeter pulse signal. Although it has not yet reached the target accuracy error of ±0.5% according to the API MPMS Chapter 5 industry standard (due to limited low-cost components and laboratory scale), this simulator has proven to be reliable and responsive as indicated by the consistency of measurement results, high linearity values (R² up to 0.9998), and the system's ability to automatically stop the flow at the setpoint volume with a final volume overshoot of less than ±1%.
