Abstract


Abstract – Spirometer is an instrument used to measure the vital capacity of the human lung and is usually only found in large hospitals or clinical laboratories because of its relatively high price. However, to find out how this instrument works, a prototype of the spirometer is made by utilizing a Labview-based interface. This prototype was developed by making an air channel or funnel the size of a human mouth which then the air will be detected by a pressure sensor connected to a signal conditioning circuit and then the measurement information data is forwarded by the Arduino to a computer to be processed into digital data which is then converted into vital capacity information data. lungs. The results obtained from this research are that it can make a spirometer prototype according to its function which is hoped to be used as a learning medium in the field of medical instrumentation by measuring the vital capacity of the lungs in the form of height, age, and gender of a person, besides that the results are in the form of a graphic display. and numerical data from the measurement process on the GUI display in LabVIEW. This prototype was calibrated using a syringe with a volume of 2 liters and the accuracy rate was 99.63% with a standard deviation value of ± 70.61 ml and a precision value of 1.76% from these results.

Intisari – Spirometer merupakan instrument yang digunakan untuk mengukur kapasitas vital paru-paru manusia dan biasanya hanya terdapat pada rumah sakit besar ataupun laboratorium klinik saja karena harganya yang relative mahal. Namun untuk mengetahui cara kerja dari instrument ini maka dibuatlah purwarupa dari spirometer dengan memanfaatkan antarmuka yang berbasis Labview. Purwarupa ini dikembangkan dengan membuat sebuah saluran atau corong udara seukuran mulut manusia yang kemudian udara tersebut akan dideteksi oleh sensor tekanan yang terhubung dengan rangkaian pengkondisi sinyal dan selanjutnya data informasi pengukuran diteruskan Arduino ke computer untuk diolah menjadi data digital yang kemudian dikonversi menjadi data informasi kapasitas vital paru-paru. Hasil yang diperoleh dari penelitian ini adalah dapat membuat purwarupa spirometer sesuai dengan fungsinya yang harapannya dapat digunakan menjadi media pembelajaran di bidang instrumentasi medis dengan variabel pengukuran kapasitas vital paru-paru berupa tinggi badan, usia dan jenis kelamin seseorang, selain itu juga hasilnya berupa tampilan grafik dan data numeris dari proses pengukuran pada tampilan GUI di LabVIEW. Purwarupa ini dikalibrasi dengan menggunakan Syringe yang bervolume 2 liter diperoleh tingkat akurasinya mencapai 99,63% dengan nilai standar deviasi adalah ±70,61 ml serta nilai kepresisiannya mencapai 1,76% dari hasil ini purwarupa
