Automatic ligthing system for windowless room based on light intensity is a system that able to improve the lighting quality with high efficiency in electrical consump. This system can adjust the brightness of the light in the room based on outdoor lighting condition. Both of the lighting conditions indoor and outdoor are detected by a sensor. For maximizing outdoor lighting, there is a servo motor that will move the curtain blinds position. The process of determining the movement of the curtain is obtained by using the input from the detection of both light sensors. Input is processed using the method of fuzzy logic, resulting in the desired output. There are 12 kinds of output of 25 conditions light sensor detection results. While outdoor lighting condition is bright then the curtain blinds will open so the room lighting using the ourdoor lighting, while outdoor lighting condition is dark then the curtain blinds will closed and the room lighting using the bulb in room. The test results of the system there are several mismatches with the desired results. Light sensor and curtains have been able to work together to make the decision making process for lighting, but the lighting intensity targets to This paper is published in Prosiding SNTI 2012 Volume 9 No. 1 Tahun 2012 ISSN : 1829 - 9156
