Abstract

Menurut laporan Indonesian Renal Registry pada tahun 2018, Indonesia masih membutuhkan sebanyak 10.492-unit mesin hemodialisis. Untuk mengatasi kebutuhan tersebut, departemen Teknik Biomedik bekerja sama dengan beberapa departemen di ITS Surabaya untuk mengembangkan mesin hemodialisis secara mandiri. Prosedur hemodialisis dilakukan dengan menggunakan larutan cairan dialisat yang terdiri dari larutan bikarbonat dan larutan asam. Dalam penelitian ini, digunakan sistem pembilasan dengan air Reverse Osmosis panas yang dirancang untuk membersihkan zat sisa pencampuran cairan dialisat, yakni kalsium karbonat (CaCO3). Penelitian ini disesuaikan dengan referensi mesin NIPRO SURDIAL 55 PLUS, dengan menggunakan dua pemanas agar mencapai suhu 80°C. Terdapat dua prosedur utama yang dilakukan, yaitu pembilasan dengan air panas dan pendinginan saluran. Selanjutnya, dikembangkan metode pembuktian kebersihan saluran dengan menggunakan sensor konduktivitas setelah seluruh prosedur selesai dilakukan. Hasil pengontrolan pemanas pada suhu 80°C menunjukkan hasil respon yang optimal, dengan nilai Kp, Ki, dan Kd masing-masing sebesar 300, 100, dan 50. Dengan pengaturan ini, dua pemanas dapat mencapai suhu 80°C dalam waktu sekitar 127 detik, dengan overshoot minimum sebesar 12,5% atau sekitar 90°C. Selanjutnya, dalam percobaan pembilasan saluran dengan dua skema, diperoleh hasil pembilasan yang optimal selama 10 menit dengan nilai konduktivitas sebesar 382.367 µS/cm. Nilai ini mendekati nilai konduktivitas air murni, yang umumnya berada di bawah 200 μS/cm.

Based on Indonesian Renal Registry on 2018, Indonesia still needed 10,492 units of hemodialysis machines. Based on this data, the Biomedical Engineering department collaborated with several departments at ITS Surabaya to independently develop hemodialysis machines. The hemodialysis procedure was performed using fluid solutions containing bicarbonate and acid solutions. In this research, a hot Reverse Osmosis water system was designed to clean the residual substance of the dialysate fluid mixture, namely Calcium Carbonate (CaCO3). This research was adapted from the reference machine, NIPRO SURDIAL 55 PLUS, which utilized two heaters to achieve a temperature of 80°C. The research involved two main procedures: rinsing with hot water and channel cooling. A method for verifying the cleanliness of the channels using conductivity sensors was developed after completing the entire procedure. The results of temperature control at 80°C showed an optimal response with proportional, integral, and derivative (PID) values set at 300, 100, and 50, respectively. With these settings, the two heaters could reach a temperature of 80°C in approximately 127 seconds, with a minimum overshoot of 12.5%, reaching around 90°C. Furthermore, during the rinsing experiments with the two schemes, an optimal rinsing result was obtained within 10 minutes, with a conductivity value of 382,367 µS/cm, which is close to the conductivity of pure water, typically below 200 μS/cm.
