The need tools to support the learning process for Colleges need to be examined properly so that the intent and purpose of learning can be done and can reduce the investment cost as economical as possible. The foregoing applies particularly to computer -based courses that require substantial investment costs, but life is quite short. Currently there are several obstacles that occur ineffectiveness of organizing the learning process, especially for courses Operating Systems, Computer Networking Systems, Distributed Computer Systems, Programming Client / Server or even for special courses / local content of the Linux operating system , Linux Programming. Ineffectiveness of these subjects can be measured by the level of understanding of the subject as well as the rate of the value of the subject. This study is expected to be designed and in implementing and deploying a network system based on the Linux operating system to support the implementation of the course Operating Systems, Computer Networking Systems, Distributed Computer Systems, Programming Client / Server , or can even be developed implementation of new subjects such as, Linux Server, Linux programming. These is run on a computer network architecture that has been there, but not change or damage the existing network system. Keywords: Linux Terminal Server Project (LTSP), Secure Socket Layer (SSL), Open Source, Secure Socket Host (SSH)

Problems faced by users of information technology one of which is the size of large files that need a large storage media, and required a long time to save it. By compressing a large file is a solution to save time and storage media. Compression system was extensive but because of the limitations, the theme of which will be described on this occasion only covers problems in the system comparison of the results of the compression of a file into the software by using algorithms Run Length and Two Level Hoshing. With the aim to build software that can support the compression system, does not always have to provide large storage media and time efficiency. Keywords: algoritma Run-Length, Two-Level-Hoshing, Compression, Decompression

An educational institution need of all the assets to support its activities. Assets, include Fixed Assets and Current Assets. Both assets must be managed properly since submited to the deletion process. Current asset management in STMIK Mardira Indonesia still done manually. Based to the important of the role of assets in supporting the activities in this research, tryes to design and implement Information Systems Object-Oriented Processing Assets. This Information Systems Object-Oriented Asset was limited to the process of submission of goods, purchase of goods, receipt of goods, distribution of goods, mutation and deletion process of inventory items and consumables. Information Systems Object-Oriented Asset Processing was developed through analysis using use case model, which is implemented in the PHP programming language and Java Script EXTJS version 2.2 with the MySQL database version 5. Through programming tools, it is expected that information systems can be applied easily operated and provides added value in the management of assets in STMIK Mardira Indonesia. Key Word : system, information, object, fixed asset, curent asset.

In an effort to improve the welfare of the people of Indonesia, the government seeks to promote development in all fields. One is the pharmaceutical sector has an important role in meeting the needs of the community. A business entity in London that specializes in the manufacture of drugs to realize that the situation of intense competition in today's business world, the company is required to make efforts so that the product can be accepted by consumers. One way is to pay attention to what the consumer preferences, among others, the quality of the products with good quality products, it is expected that production will increase productivity so that the company can maintain its presence in the business world. The method used is descriptive method of analysis is a method of describing the problems being faced by collecting data , then processed and put them together . The author uses the Linear Regression Analysis, Correlation coefficient, coefficient of determination and t test statistics. Data on Quality and Productivity Production Costs were used from 2002 to 2007. Keywords: Quality Control, Cost of Quality, Productivity Production

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.
