Abstract

Single tuition is the extension of the single tuition, which can be interpreted as a payment system made at the time of admission in both State and private colleges in Indonesia. Where this single tuition can provide benefits for the equitable of each student and help the students who are less able in terms of the economy that is certainly derived from the underprivileged family. In the calculation process determines the single tuition money each student needs a long process and time. So, there is an idea to implement a Decision Support System Dynamic (DSSD) so that at the time of determination of single tuition can be evenly and by the actual situation. One method that can be used on DSSD is the Weighted Product (WP) method. By implementing the method of WP combined with the concept of DSSD, then generated values of confusion matrix (recall, precision, f-measure, and accuracy) obtained by looking for the value of comparison between test data with pattern data. Obtained confusion matrix value with system testing and get the results Precision 88.89%, Recall 82.76%, Accuracy 77.14%, F-Measure 85.71%.

Abstract

Message sending is one activity that is often used by everyone. However, security in this message delivery system needs to be wary of spying or message piracy during the process of sending messages. Surely someone who sent the message does not know if someone's personal message has been stolen. With this initiative builds a security message using cryptographic RSA algorithm where the message sender or recipient of the message can send the message safely without being known to the message hijacker or spy. Cryptography that uses the RSA algorithm to secure messages. This RSA algorithm message will be decrypted with the public key and to encrypt the message. This application was built on the Android platform because the dominant person has an Android smartphone with a system that runs the length of the message character does not affect the speed at the time of sending the message to the recipient, and there is no limit on the length of the message character during the encryption process so that any length of the massage character can be encrypted well.
