In order to solve very difficult problems, we often compromise on speed and systematic, and control structure that ensures obtaining the best answer. It is used what is called the search process. Search is a technique of searching for answers by examining the various alternatives that exist in the knowledge base. This leads to new facts and finally arrives at an answer or solution. The main method is a heuristic search. Heuristic is a rule that a method or procedure that is based on experience and practice, advice, tricks or other assistance that helps narrow down and focus the search process for a particular purpose. So when doing a search may appeal from the existing knowledge base matches what is expected by the user to find the fastest and shortest. One application of search methods is the following problems, achieving the goal state at 8 puzzles game. Require steps or a solution to be able to reach the state goal state. A search algorithm is to find a solution would be to use a heuristic. This heuristic method is used to narrow down the possibilities that exist in conducting the achievement goal state. In AI known as search method best first search, which is one method that utilizes the advantages of the method and depth first search and breadth-first, where this method is used to determine the direction of motion in the search space.

Data security is now an issue of vital importance to the world today, especially information concerning the company confidential or secret state that its presence should not be known by others. Since ancient times the security or confidentiality of information is the key to success for the authorities or the king in winning the war, so that information about the war should not be known or leaked to the enemy. In the world of informatics data security has become an object that has been developed over the years. Even emerging data security techniques such as steganography and kriftografi. At this time many emerging methods or data security techniques are quite diverse as disguises the data in a particular image or icon, encryption, passwords, or even the installation of hidden data is that it can not be known by others in this study, the authors tried to make the data contained in a folder can not be known by others with a shape like recyle bin. This is called the security system security through the system registry window, where the registry is the heart rather than the system window. By doing registry to a folder, then the folder will be registered into a recycle bin, and the folder will change the function into a recyle bin. With this kind of expected menggunakanmetode data contained in a folder can be maintained in the data security, thus the continuity of data will be maintained and safe.

Salary is income received by the employee which is one element of the cost that needs to be controlled. Therefore, the internal control system is necessary for the purpose of securing the property, generate data that would be credible , improve operating efficiency and encourage the implementation of all policies that have been set by the company can be adhered to. So that internal control is running properly it needs a good accounting system to monitor abuses form irresponsible parties so as to prevent harm to the company that may occur. The method used is descriptive and verification method by means of multiple linear regression equation analysis, correlation coefficient, coefficient of determination, and hypothesis testing using t test and F. Using multiple linear regression obtained by the implementation of payroll accounting system will streamline the internal control system Y = 15.551 + 0,828X1 + 0,373X2 + 0,077X3 - 0,054X4 + 1,140X5, while the correlation analysis results obtained R = 0.729 (very strong). The results of the analysis coefficient of determination obtained Kd = 53.14 % , indicating that the payroll accounting system plays a role in effecting internal control system by 53.14 % , with the t test obtained significant role of organizational structure t = 5.162 , documents and accounting records t = 3,505, payroll accounting procedures t = 3.437, t = 4.998 destinations > table = 1.684, t = -0.288 while report < table = -1.684 means that the report does not contribute significantly, while simultaneously obtained F count = 7,724 > Ftable = 3.255 then Ho is rejected and Ha accepted , meaning that the accounting system recitation significant role in effecting the salary system of internal control.

PHP is a web-based programming language in which the system is implemented on the server side. PHP can be inserted between the HTML language scripts and other server side language arena, with it then PHP will be executed directly on the server. While the browser will execute the web page through which the server will then receive the display “results so" in an HTML form, whereas PHP code itself will not be visible.

Mobile phones (cell phones) are now used not only for conversation but also to play games and so on. The presence Java2 Micro Edition (J2ME) is expected to answer those needs while making more multifunctional mobile phones. Currently the latest generation of mobile phones has the ability to apply the J2ME program, which is a Java program that is specifically designed for mobile devices. Java enabled mobile applications meet the needs of its users through a variety of exciting programs. Because it can be done offline phones not only can be used as a communication tool but it can also be used as tool translator English words into Indonesian.

Technological developments in the growing industrial machine encourage industrial companies spend significant investment in order to adopt the technology to produce a quality product. In the industrial machine management operations management integrated with a variety of factors, including the cost of maintenance. Maintenance that will either keep the consistency of production so that the company can maintain production capacity. PT. X as a manufacturer of materials for industrial use today is preventive maintenance and breakdown maintenance. While the company is still facing towards the maintenance of the machine, it can be seen from the data operations engine unit 258 during the year 2008, there were an average of 6 units damaged machine per month. In this study, the research method used is descriptive analysis using quantitative analysis, using descriptive analysis, regression analysis and correlation analysis. Test equipment used is the F test to test the direction of the regression coefficient of determination. The results showed that the role of engine maintenance to quality production at PT. X was not significant, as indicated by a correlation coefficient of 0.2131 and based on regression equation Y = 0.9765 + 9E - 10 ( X ). In addition to the value of the correlation coefficient r = 0.2131 actual show showed no positive role between the cost of maintenance of the quality of the product, but it is very small, because only reaches r2 = 0.0454 or just 4.54 % The results show that the value of F = 0.4758 is not significant enough to reject Ho, meaning no maintenance costs contribute significantly to the quality. Thus the research hypothesis in the case of the production of the 2008 data sample could not be proven means that there are other factors that have a positive role to the quality of production in addition to the cost of maintenance of production machinery
