Abstract

Indonesia, most cyber incidents reported by respondents relate to loss or leakage of business information such as internal records, information related to customers, employees and intellectuals. This worries the misuse of information held by irresponsible parties. in order to protect information so that it is not misused by unauthorized parties, then an attempt is made to hide the actual information on other information called steganography by using the Least Significant bit (LSB) method and to see the image quality value containing the message using the MSE calculation (Mean Square Error) and PSNR (Peak signal to noise ratio). The process of inserting messages is successfully carried out and produces extraction steganographic images. From testing the picture it can be concluded that the results of the steganography application must be invisible or not visible in plain view, as the purpose of this study is to increase the security sent to arrive at the recipient.

Abstract

Algebra is one branch of mathematics that studies simplification and problem solving using symbols that are substitutes for constants or variables. Algebra in middle school children is usually obtained in class VII where the learning process uses textbooks and practices are simple. On the other hand, as more and more interactive learning media emerge that teach children, then with these considerations, the authors took the initiative to build a Mobile-Based Algebra Form Learning Media Design that can help the learning process more interesting.

Supporting Puskesmas staff every day must go to the Puskesmas to attend attendance when they come and go home, so that fraud arises in making attendance by making attendance care.Attendance system using the QR Code, can easily search data and minimize fraud in attendance care, because the QR Code must scan. The QR Code scanning results will be saved in the database. The QR Code is made with the Puskesmas Employee Identification Number. The results obtained from the Implementation of the Quick Response (QR) Code for the attendance of Puskesmas are able to facilitate employees in making attendance and the head of administration to get information on the attendance of Puskesmas Payung Sekaki employees.

Abstract

The campus area is a place for students and teaching staff to carry out their routine activities. But there are times when campus visitors are not only focused on teaching staff or students who already know the ins and outs of the campus area. Some parties such as students' parents, new students, guests sometimes need a certain guide to find specific areas of interest in the campus area. The development of this application is carried out aiming to assist and alleviate these parties to search and find related areas. The design of the software is made with Adobe Edge Animation CC with Action Script 3.0. based on the results of this study it can be concluded that the Digital Mapping Application on the Muhammadiyah Riau Campus can overcome the problem of confusion among the parties when visiting the Muhammadiyah Riau campus.
