Abstract

ABSTRACT Gold has become one of the inventions that people are interested in. The high resale value makes many people save it as a substitute for savings. But the price of gold is influenced by several things such as economic conditions, the level of demand and supply or the existence of goods, this has encouraged some parties to make predictions of gold prices to avoid unexpected losses going forward. Based on these problems the researchers tried to predict gold prices using the K-Nearest Neighbor (K-NN) method and Linear Regression. The K-NN method is used to classify the data that is owned to then make predictions using Linear Regression. From the test with the number of training data as many as 4305 data and test data as many as 402 data, the root mean square error value of 5.807% was obtained. Keywords: gold investment, gold price prediction, K-Nearest Neighbor, Linear Regression

Abstract

School management information system is an important application used to manage data and information of a school in order to provide the best service to the community. To create an effective and efficient information system, an effective database design is needed. This needs to be done because if the database is not designed properly, in the future when a system starts to develop, the integrity data stored in the database will decrease. One aspect that needs to be considered is database security. Database security is very important, because the data stored in the database is important information for schools, such as student, financial and employee data. One of the method that can be used to improve database security is Role-Based Access Control (RBAC), which is limiting access to users or roles according to their respective roles. In this study the RBAC method was applied in school management information systems using the PostgreSQL database.  Keywords:  Role Based Access Control, RBAC, Database Security, PostgreSQL, SIM Sekolah

Abstract

Many factors must be considered in terms of security when communicating using information technology. SMS is one of the features that are embedded in a mobile phone is no exception in android phone. SMS is still widely used for the exchange of information, many users inadvertently share information that is privacy by sending a message by SMS. Messages that are done with SMS will be received by the provider of the service provider, then after it was forwarded to the recipient therefore sending a message by SMS need to be protected, so that the safety messages are kept strictly confidential. In this study, the software will be built in order to improve the security of messages via SMS. The application will be built to encrypt a message that will be sent and decrypt incoming messages via SMS. Applications built using the RC6 algorithm. RC6 algorithm is an algorithm flow block (block cipher) were included into the type of symmetric key cryptography system. RC6 algorithm implementation is built using Android technology, to protect and maintain the confidentiality of messages. The results of trials that have been done with this application, encrypts messages sent and can decrypt a message that was well received, the message can only be decrypted if entered the correct key corresponding to the message encryption key at the time. This application can only perform encryption and decryption of text messages (letters, numbers, symbols), to encrypt the decrypted form of the image file can not be done with this application. Keyword : SMS, Android, Cryptography, Algorithms RC6.

Abstract

Analysis of Support Vector Machine (SVM) implemented on prediction of production rice commodity that can help the management of rice production in Indonesia. Prediction is done with Matlab R2016A especially function of SVM Regression. The prediction results were evaluated by performance criteria such as Root Mean Squared Error (RMSE), R-Squared and Adjusted R-Squared, and also curve fitting. SVM parameters determined automatically after processing is completed. Predictions done annually, conducted from 2006 to 2015. The results of those predictions determined the value of performance to get the value of the correspondence between the predicted value and the actual value and the best prediction is illustrated by curve fitting. It also conducted comparison performance of predictions per year to determine which ones produce the best fit. Results of prediction rice commodity with SVM method showed that the best fit is prediction in 2007 with RMSE value of 1.20E+06, R-Square of 0.794 or 79.4%, Adjusted R-Square of 0788 or 78.8%, as well as curve fitting shows the level distribution predictions are optimal for the year. Keyword: SVM, regression, prediction

Abstract

Canteen is one of the most important places to be owned by a particular institution including educational institutions such as universities, in the canteen itself there are sellers - sellers who are the main factors that determine the consumer's decision to the canteen. in this study we will discuss how to determine the priority weights of criteria to be used as an evaluation parameter for the selection of prospective sellers who will be accepted in a canteen. The method used is the Analytical Hierarchy Process (AHP), the stages in the AHP method begin with the process of defining the problem, making a hierarchical structure that begins with general objectives, followed by criteria and alternative choices, Creating pairwise comparison matrices, normalizing data, calculating values eigen vector and test its consistency, calculate eigen vector from each paired comparison matrix, test the consistency of hierarchy. If it does not meet with CR <0.01, the pairwise comparison process must be carried out again. The results of this study are a priority weight of each criterion that will be used for the selection process of prospective sellers in the canteen.Keywords: Canteen, AHP, criter
