Monitoring of Blood Cholesterol Measurement System Using ICT-Based Non-Invasive Methods

Abstract

Coronary heart disease is a public health problem because of its very high morbidity and mortality, the death rate caused by coronary heart disease is quite high in the world, including in Indonesia. Many factors trigger an increase in coronary heart disease, one of which is cholesterol. Cholesterol is a fat molecule (sterol) contained in the membrane of blood cells. Cholesterol is normally produced by the body in the right amount, but if it is excessive it will cause the thickening of the walls of the arteries so that it makes the blood flow narrow which results in a heart attack or brain hemorrhage (stroke). In general, cholesterol can be measured using an auto-check strip device or you can also go to a clinic or hospital for invasive blood sampling which can leave traumatic pain in the patient. Currently, there are many developments for measuring blood cholesterol using Non-invasive methods. This research was developed from previous research by utilizing a near-infrared sensor with a wavelength of 950nm based on ICT by displaying measurement results on a web base, this design can be an alternative for routinely measuring cholesterol levels. This research was conducted using a near-infrared sensor with a random sample of 25 people in two conditions, namely the condition before meals and the condition after meals, where the results of this test obtained an accuracy of 98.47% in conditions before meals and 98.55% in condition after meals.
