Abstract

Penyakit Ginjal Kronis (PGK) merupakan masalah kesehatan masyarakat global dengan tingkat prevalensi yang terus meningkat, dimana sekitar 2 dari 1000 populasi masyarakat Indonesia menderita PGK. Ketika penyakit ginjal kronis sudah memasuki stadium terminal, terjadi kegagalan fungsi ginjal dalam menyaring darah sehingga fungsinya perlu digantikan melalui proses cuci darah menggunakan mesin hemodialisis. Proses dialisis mengakibatkan hilangnya panas tubuh, yang dapat mengakibatkan komplikasi pada pasien. Panas tubuh yang hilang dapat dikompensasi dengan penggunaan suhu cairan dialisat yang tepat, yakni pada rentang suhu normal tubuh manusia. Temperatur cairan dialisat yang tepat didapatkan dengan mengontrol suhu air reverse osmosis sebelum masuk kedalam sistem pencampuran dialisat pada rentang 35 – 41°C. Sehingga pada penelitian ini, akan dirancang sebuah sistem kontrol dan penyiapan air reverse osmosis untuk pencampuran dialisat dengan tujuan untuk menjaga temperatur air yang masuk stabil pada nilai suhu yang ditetapkan. Pada sistem yang diteliti, digunakan sensor PT-100 untuk membaca nilai temperatur air. Sistem kontrol yang digunakan dalam penelitian ini adalah sistem kontrol PID. Sistem kontrol PID digunakan untuk mengontrol aktuator berupa pemanas berdasarkan umpan balik dari sensor. Didapatkan hasil rata-rata error pengukuran kedua sensor sebesar 0.281% dan 0.194%. Dari pengujian sistem kontrol suhu, didapatkan nilai parameter Kp, Ki, dan Kd sebesar 51, 2.04, dan 325.125. Sistem kontrol mampu memanaskan air hingga mencapai suhu 36°C dalam waktu 200 detik

Chronic Kidney Disease (CKD) is a global public health problem with an ever-increasing prevalence rate, where around 2 out of 1000 Indonesian population suffer from CKD. When chronic kidney disease has reached terminal stage, there is a failure of kidney function in filtering blood so that its function needs to be replaced through dialysis process using a hemodialysis machine. The process of dialysis results in loss of body heat, which can lead to complications of the patient. The loss of body heat can be compensated by using the right dialysate fluid temperature, which is in the normal temperature range of the human body. The correct dialysate fluid temperature is obtained by controlling the reverse osmosis water temperature before entering the dialysate mixing system in the range of 35 – 41℃. Therefore, in this study, a reverse osmosis water preparation and control system is designed for dialysate mixing with the aim of keeping the incoming water temperature stable at a set temperature value. In this study, PT-100 sensor is used to read the water temperature value. PID control is used as the control system in this study. The PID control system is used to control actuators in the form of heaters based on feedback from sensors. The average results of the measurement errors of the two sensors were 0.281% and 0.194%. Based on the temperature control system testing, the parameter values of Kp, Ki, and Kd obtained were 51, 2.04, and 325.125. The control system can heat water up to 36℃ within 200 seconds
