ABSTRACT
The purpose of this research is to study how to use electricity, is appropriate and save. How the study was to observe and record the behavior user of the electric lights in walkways, bathrooms at Faculty of Computer Engineering Building in a regular class. That information to designed the control device to suit the usage characteristics. The study found that the toilet lighting is total time is about 18 hours per day, or about 80 percent of users do not turn off the toilet light. The walkways to enable lighting from 19.00 pm until 8.00 pm, When the officers came to work. Total time is about 13 hours per day, then you will see that it is not worth it. Consumption occurred So I see that should solve the problem by switching control to turn off power automatically install the switch general lighting in the target areas Results from continuing operations showed that such an action could solve problems caused economical and cost-effective to use lighting more than conventional operations.
