This research aimed to design and manufacture a light intensity control system based on Pulse Width Modulation (PWM), then integrate it with a high power UV-LED fluorescence imaging system. In addition, this research also aimed to test the light intensity control system that has created and integrated with a high power UV-LED fluorescence imaging system. The design of system was made using CoralDraw software. The manufacture of system was done by preparing tool and material, installing component, and checking tool. Integration of the system was done by placing a sub-system of light intensity control system that has made in the top of the high-power casing UV-LED fluorescence imaging system that made for multiplex. The testing of system includes linearity and precision. Linearity testing was done with variations of duty cycle values ranging from 25 to 250 at interval of 25, while precision testing was done by repeating the measurements of each of duty cycle value 10 times. The results of research showed that the PWM-based light intensity control system had been successfully designed and manufactured, and had been integrated with the high power UV-LED fluorescence imaging system. Besides, a PWM-based light intensity control system that had been manufactured and integrated with a high power UV-LED fluorescence imaging system had been tested. The testing results showed that the linearity of system was 0.9197 and the precision was 99.9629%. %Z Frida Agung Rakhmadi, M.Sc
