Abstract

Prevalensi hiperkolesterolemia terus meningkat dan diperkirakan menyebabkan 2,6 juta kematian dan 29,7 juta kecacatan per tahunnya. Penderita kolesterol diharapkan untuk selalu memonitor kadar kolesterol darahnya, namun proses pengukurannya masih dilakukan secara invasif dan memiliki beberapa kekurangan, oleh sebab itu perlu dikembangkan metode pengukuran secara non�invasif berbasiskan metode transmitansi menggunakan spektroskopi infra merah. Metode transmitansi merupakan teknik pengukuran non-invasif dengan melibatkan pengukuran cahaya yang diserap atau dipantulkan oleh jaringan manusia dan merupakan salah satu teknik dimana gelombang inframerah dekat diterapkan dalam penyerapan cahaya untuk menentukan kadar kolesterol. Oleh karena itu, dalam penelitian ini akan dilakukan perancangan prototipe alat ukur kolesterol darah non-invasif. Prototipe dirancang menggunakan LED inframerah dekat dan sensor fotodioda untuk mengukur kadar kolesterol darah yang dikendalikan oleh mikrokontroler Arduino Mega 2560. Selanjutnya hasil pengukuran dapat ditampilkan pada layar LCD Nextion. Hasil uji coba prototipe menghasilkan nilai akurasi 98,75% untuk pengujian alat ukur kolesterol darah dengan NIR LED 940 nm dan 97,31% untuk pengujian alat ukur kolesterol darah dengan NIR LED 1550 nm. ***** The prevalence of hypercholesterolemia continues to increase and is estimated to cause 2,6 million deaths and 29,7 million disabilities annually. Cholesterol patients are expected to regularly monitor their blood cholesterol levels; however, the measurement process is still conducted invasively and has several drawbacks. Therefore, it is necessary to develop non-invasive measurement methods based on transmittance using infrared spectroscopy. The transmittance method is a non-invasive measurement technique involving the measurement of light absorbed or reflected by human tissue and is one of the techniques where near-infrared waves are applied in light absorption to determine cholesterol levels. Therefore, this study aims to design a prototype of a non-invasive blood cholesterol measuring device. The prototype is designed using a near-infrared LED and a photodiode sensor to measure blood cholesterol levels, controlled by an Arduino Mega 2560 microcontroller. The measurement results can then be displayed on a Nextion LCD screen. The prototype testing results showed an accuracy of 98,75% for the cholesterol measuring device with a 940 nm NIR LED and 97,31% for the device with a 1550 nm NIR LED.
