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.
