Abstract

Ginjal adalah organ penting dalam tubuh manusia yang berperan dalam menjaga keseimbangan zat dalam darah melalui proses penyaringan. Zat-zat sisa hasil metabolisme tubuh, seperti makanan, obat-obatan, dan racun, disaring oleh ginjal sebanyak 120-150 liter per hari. Namun, kasus gagal ginjal di Indonesia mencapai angka yang mengkhawatirkan, dengan 325 kasus dan 195 kematian dilaporkan pada tahun 2022. Terapi hemodialisis menjadi metode yang umum digunakan untuk membersihkan darah bagi pasien gagal ginjal. Terapi ini melibatkan dua tahap proses, yaitu pre-treatment dan treatment. Dalam penelitian ini, fokus ditujukan pada pembuangan gelembung udara selama pre-treatment. Penelitian ini menggunakan sistem embedded dengan mikrokontroler Teensy4.1 dan perangkat keras, seperti sensor ultrasound ZBU06, sensor flow YS-F401, solenoid valve, dan lainnya. Sistem ini bertujuan untuk mengukur volume gelembung udara yang terdeteksi. Setelah volume gelembung udara terdeteksi, pompa air akan mengisi cairan dialisat hingga volume cairan mencapai jumlah gelembung yang terdeteksi. Ketika sensor flow menerima input HIGH sebagai umpan balik, solenoid valve akan membuka hingga sensor mendeteksi input LOW saat pompa berhenti dan volume air sama dengan jumlah gelembung yang terdeteksi. Setelah percobaan dilakukan, sensor ultrasound menunjukkan akurasi sebesar 0,957641396, sensor flow memiliki akurasi 0,9508788, dan pompa memiliki stabilitas dengan PWM value 45 sebesar 491,76 mL/menit. Hasil uji integrasi sistem menunjukkan akurasi rata-rata keseluruhan sistem sebesar 0,94988. Penelitian ini memberikan kontribusi penting dalam pengembangan sistem hemodialisis yang lebih efektif dan akurat. Dengan teknologi ini, diharapkan penanganan gagal ginjal dapat lebih baik lewat menjaga efektivitas kinerja mesin hemodialisis ITS.

The kidney is an important organ in the human body that plays a crucial role in maintaining the balance of substances in the blood through filtration. Waste products from the body's metabolism, such as food, medications, and toxins, are filtered by the kidneys at 120-150 liters per day. However, the number of kidney failure cases in Indonesia has reached concerning levels, with 325 cases and 195 deaths reported in 2022. Hemodialysis therapy has become a common method used to cleanse the blood of patients with kidney failure. In this study, the focus was on removing air bubbles during the pre-treatment phase. The researchers used an embedded system with the Teensy4.1 microcontroller and hardware components such as the ZBU06 ultrasound sensor, YS-F401 flow sensor, and solenoid valve. Once the volume of air bubbles was detected, the water pump would fill the dialysate fluid until its volume matched the detected bubble volume. When the flow sensor received a HIGH input as feedback, the solenoid valve would open until the sensor detected a LOW input, indicating that the pump had stopped and the volume of water matched the number of detected bubbles. After conducting the experiments, the ultrasound sensor showed an accuracy of 0.957641396, the flow sensor had an accuracy of 0.9508788, and the pump demonstrated stability with a PWM value of 45, corresponding to a flow rate of 491.76 mL/minute. The results of the system integration test indicated an overall system accuracy of 0.94988. With this technology, it is hoped that the management of kidney failure can be improved, prolonging the life expectancy of patients and reducing mortality rates associated with this condition.
