Faced by consumers today's information technology is how to make a good circuit, which can be controlled by a computer, which is expected to help the human performance effectively and efficiently. System control electronic equipment in this study, will explain the process of communication between the computer with a series microcontroller serial data communication is done. The system will transmit data bits 0 and 1 to the microcontroller circuit through COM channels contained on the computer. The bits of data to be converted in the form of a specific amount that can be understood by the microcontroller AT89C51, which aims to control electronic equipment. Data bits 0 aims to ensure electronic equipment and bits 1 aims to turn on electronic equipment.

The main study of this research deals with the problem of planning the production process in a job scheduling operations. The problem that arises is how to determine the appropriate time allocation of available resources that affect the production mechanism. This problem is more focused on the management of time allocation on a set of machines to complete the production work efficiently. In this study using a genetic algorithm approach to solve the problems of the working plan (time schedule), namely the identification based on the results of the measurement inputs, then operated to obtain an optimal operation scheduling model. The method was developed based on the method of search of a set of points in a population, which is a process of finding a production schedule that has the minimum time span, so the results are useful to determine the solutions work planning optimal operation. The technique was developed to identify the operating system of production using genetic algorithms is to find the optimum solution is done by considering many points that emerged simultaneously subsequent operations are performed through the workings of which follow an evolutionary mechanism to obtain an objective function or desired fitness function. Opportunities obtained from the genetic algorithm to find the candidate of an optimum model, determined by the extent of population size and maximum generation as input data. Further observational data obtained at random will be operated by using three crossover operators as a measure of comparison for reviewing and detect the extent to which variations are related scheduling production operations. The comparison of the three crossover genetic algorithm in building the structure of the most minimum scheduling model is the end result in determining the best type of operator.

To simplify boolean function, can be done in three ways, namely by means of algebra, Karnaugh map method, and the method of tabulation of Quine Mc Cluskey. For a Boolean function with a variable number of more than 4 will be more complicated done, for it needs to develop a software tool to help resolve the issue. Software development to help simplification of Boolean functions with Quine Mc Cluskey method aims to give the facility a tool for those who are studying the simplification of Boolean functions, because the software is able to resolve the problem of simplifying Boolean functions along with the steps the number of variables that have been determined.

Access information on a college academic easily, quickly, and accurately has been a matter that must be considered by the college. With a system of academic services that easily allows students to access their academic information anywhere and anytime. Obviously this will have a positive impact both for students, universities, and foundations that can make the system as one of the capital which can be used for promotional purposes college. One form of academic information access system that can anticipate those needs are academic -based wireless access system user application protocol (WAP). In the system developed in this study is simulated by using a mobile phone and academic websites that are connected to the existing academic system in a college.
