PROTOTIP TERAPI INFRAMERAH DILENGKAPI PEWAKTU DENGAN TAMPILAN SEVEN SEGMENT DAN PENGATURAN INTENSITAS CAHAYA BERBASIS DIGITAL

Abstract

At the time of the author undergoing  field practice at the hospital, there is a plane theraphy. Aircraft teraphy ersebut using infrared light using an analog timer settings. Conditions teraphy infrared aircraft is still in good condition. But teraphy operator told me about the plane, the plane analogue timers often do not work properly, so it is often improved. Operators also complained about the lack of display timer, it makes the service a bit of confusion. Teraphy plane is also no infrared light intensity settings.

By looking at the problem the writer trying to do some form of effort to design a device with the title "Prototype Infrared teraphy In Timer Complete With Seven Segment Display and Digital-Based Light Intensity Settings". This tool comes with a choice of teraphy 10, 20, and 30 minutes were enabled to choose the length of the therapy process. There are also settings in the settings low medium high light intensity which functioned to regulate the light intensity.

By using the computation time in the selection of a 30-minute known standard deviation of 1.61, error of 0.48%. The timing of 20 minutes unknown standard deviation of 1.11, the error of 0.5%. The timing of 10 minutes unknown standard deviation of 0.6, error of 0.51%. And by using the calculations in the selection of low intensity can be known standard deviation of 0.5, error of 0.06%. Selection of medium intensity can be known standard deviation of 1.4, the error or errors by 0.1%. Selection of high intensity can be known standard deviation of 0:23,  error of 0.02%.
