Abstract: “This paper, introduced a non-invasive jaundice detection using optical technique. Jaundice is a condition when baby skin, eyes and other tissues became yellow. The yellow came from bilirubin pigment that bound with albumin before breakdown. If too many breakdowns of hemoglobin in one time, liver couldn’t excreted all bilirubin. For babies, bilirubin will cause brain damage if its too high more than 10mg/dL inside them. It happened when bilirubin became toxic dice and go to the brain that cause death. There are two techniques of detection bilirubin namely invasive technique and non-invasive technique. The differences of this technique are invasive technique was painful then non-invasive technique and it have to take some blood to be analyzed. Both methods used the principle of Lambert law as references and guide to measure bilirubin inside babies”
