PHOTOTHERAPI DENGANPENGATURAN KOLIMATOR BERBASIS MIKROKONTROLLER

Abstract

Fototerapi is the use of therapy beam of high intensity. Fungsion for the treatment or light
therapy in jaundiced newborns.theraphy a baby that have hyperbilirubin disease or are being
accumulation bilirubin in tissue under skin or mucous membrane that marked by jaundice . The
basic principle of this equipment are that give a ray on the baby skin directly with period timing that
determinded.
All this time phototherapy that have made still using digital system, therefore in this thesis the
author tries to develop a tool that made phototherapy with setting colimator based mikrokontroHer
Atmega8535. There are 2 modes in this device are high mode and low mode on the lamp and then right Then
there is the selection of the left or right to adjust width of the irradiation.
After doing measurment using calibrator ( stopwatch ) against time get prosented error deviceis
1,4% when measuring hours. The results of analysis of the voltage measurement obtained MOC
percentage error of 0,9% in the active and off 0,61%. Then the percentage error in the voltage TRIAC A2
tool %obtained an average error of 0,59% and 0,95% while active inactive.
