Abstract

Manekin vaskuler adalah alat untuk mensimulasikan sistem kardiovaskular manusia pada pembuluh darah arteri dan vena sebagai modul pelatihan. Namun, manekin vaskuler yang tersedia di pasaran saat ini umumnya memiliki keterbatasan hanya difokuskan pada fungsi sederhana dan hanya memiliki satu pembuluh vena tanpa fitur lanjutan seperti kemampuan untuk mengontrol laju aliran darah sehingga tidak dapat merepresentasikan kondisi gangguan seperti penyempitan pembuluh darah. Proyek akhir ini membuat manekin vaskular yang menggunakan mikrokontroler ESP32 untuk mengendalikan pompa diafragma yang memungkinkan pengaturan aliran darah yang presisi dan stabil terhadap gangguan dengan menerapkan algoritma Proportional-Integral-Derivative (PID) untuk mempertahankan laju aliran. Performa manekin vaskular dievaluasi melalui berbagai skenario, dengan fokus pada stabilitas aliran darah dan efektivitas representasi dari pembuluh darah arteri dan vena. Evaluasi performa dilakukan dengan menguji respons sistem terhadap parameter PID yang ditentukan menggunakan metode Ziegler-Nichols. Hasil pengujian terbaik menunjukkan sistem mampu menstabilkan flowrate dengan setpoint 800ml/min dengan nilai rise time rata-rata selama 9,2 detik, dan overshoot sebesar 0,62%. Hasil penelitian menunjukkan bahwa sistem kontrol PID yang diterapkan terbukti efektif dalam mempertahankan laju aliran darah sesuai dengan setpoint yang diinginkan.

A vascular mannequin is a tool for simulating the human cardiovascular system in arterial and venous blood vessels as a training module. However, vascular mannequins currently available on the market generally have limitations, focusing only on simple functions and having only one vein without advanced features such as the ability to control blood flow rate, making them unable to represent conditions such as blood vessel constriction. This final project creates an innovative vascular manikin that uses an ESP32 microcontroller to control a diaphragm pump, enabling precise and stable blood flow regulation against disturbances by applying a Proportional-Integral-Derivative (PID) algorithm to maintain flow rate. The performance of the vascular manikin was evaluated through various scenarios, focusing on blood flow stability and the effectiveness of representing arterial and venous blood vessels. Performance evaluation was conducted by testing the system's response to the specified PID parameters using the Ziegler-Nichols method. The best test results showed that the system was able to stabilize the flow rate at a setpoint of 800 ml/min with an average rise time of 9.2 seconds and an overshoot of 0.62%. The research results indicate that the applied PID control system is effective in maintaining the blood flow rate according to the desired setpoint.
