The Admissions in the College of Technology Adisutjipto Yogyakarta, the committee has had PMB Computer Based Test (CBT) to test new students since 2010. However, CBT is owned by STTA not support randomization and answer questions about each exam so issued, the order of questions and answers will remain the same. Of the many random algorithm, algorithm Congruential Linear Generators (LCG) is an algorithm suitable for use in scrambling about in CBT because of the rapid process of generating random numbers and the algorithm is easy to learn and implement. By giving feedback LCG a current value of the length of time it will produce a different value in each random from the first randomization. With randomness about the cheating in the exam PMB can be resolved.

Wireless networks / hostspot using wave or signal transmission media. Waves or signals emitted from a device called an access point having a particular frequency. Signal beam is formed a circular pattern in which the antenna from the access point to the source signal. In a wireless network signal is captured and used a computer to be able to communicate with each other. PING technique is a method to double check the connection by sending data packets from the sending computer to the destination computer. This process can be seen from the travel time required to transmit data packets. So there is some problems how to convert time obtained from the PING into the distance. Algorithm Jawa can be used to convert units of time-based PING the wireless LAN / hostspot into the distance. Basically, two computers that are in a wireless LAN / hostspot will form a triangular pattern. This pattern will be used algorithm jawa to determine the distance between two computers within the wireless LAN / hostspot by utilizing modifications pythagorean theorem for isosceles triangular pattern and the large angle of 400.

Synchronization is the process of setting the course of several processes at the same time. Synchronization builds upon students' academic value table STTA Yogyakarta by comparing records for the records in the database. If there is a difference in the academic value of the table the different values will be returned as the value of the original with comparing by using the master database. Record based table synchronization is expected to address the security system on the database and provide security guarantees a safe and comfortable.Authentication is a process by which a user is identified by the server before the user using the network. In the process, the user is requesting access rights to the server to use a network. Authorization is the allocation of what services are entitled to be accessed by the user on the network. Authorization is done when the user has been declared eligible to use the network. Accounting is a process performed by the server to record all user activity in the network, such as when the user starts using the network, end user when the connection to the network, how long the user using the network, how much data is accessed from the network user.The results of the implementation of synchronization using a table based record system security authentication, authorization, accounting changes that may prevent the occurrence of data in a database, optimizing the use of stored, and enhance security systems at the database STTA center of Yogyakarta.

One way of written communication is to send a message to the others. With the current technological developments, written communication can be supported by the computer and internet media so that messages sent can be delivered to target internet users in a short time and geographical distance is no longer a barrier of communication. In communicating between countries is often used in English, but that will be an obstacle when the language used to write the message was not understood by the other person and vice versa. Seeing this condition, then there needs to be an alternative media to overcome these obstacles. One of them is to design a bilingual (Indonesian-English) chat translator application. The system was created using Delphi 7 as a programming language and Oracle as Indonesian and English vocabulary storage database. Through this system, users can send messages using Indonesian or English and receive messages according to language used. The result from the design of this application indicates that the application is able to translate the text that is sent into the appropriate language which is controlled by interlocutors. So it can be a solution to communicate although with different language. However, the ability of the translator is very dependent on the current record in the dictionary table, so the translation can be developed in subsequent research to be more complete and better.
