Abstract

The design of the three-tier client server architecture is a further development than before that uses two tiers. The planning is the initial stage before the implementation of the system that is already running today. With this model it is expected that the application no longer need to be installed on every client but enough on the server only.  Beside that, this model of server side application can be accessed by every client in various operating system infrastructure and hardware. The Library transaction service workload can be dispersed and no longer overlap at one work terminal only, but it can already be spread over other terminals, which is the benefit of this technology.  The integrated information system between the academic information system and library information system makes the data more accurate and well distributed. The credibility and flexibility of data is maintained due to the synchronization between servers for data usage on the main server. This kind of model system development pattern makes integration between parts of an organization better. Three tiers have a database layer on server 1, the application layer on server 2, and Layer 3 is on the user side.

Abstract

The lecture attendance application at the University of Muhammadiyah Bengkulu needs to be developed so that it is easier in the implementation process. One way to simplify the process is to use the presence of a Quick Response Code which can be done in online or offline lectures. The method used is in the form of encrypted and hashed Uniform Resource Locator storage combined with internet protocol address filtering so that the information stored in the Quick Response Code becomes more secure than in plain text. The data collection method uses observation and interview techniques to previous application users and then analysis, design and experimental programming are carried out on program modules that play a role in the presence process. From the results of this study, the Quick Response Code can be protected and used successfully and can be integrated with several learning management systems, social media applications that are often used by lecturers, especially at the University of Muhammadiyah Bengkulu. The results of this study have been used in the lecture process in the Even Semester of the 2020 Academic Year.

Abstract

The implementation of the attendance system at the University of Muhammadiyah Bengkulu needs to be developed to be more effective in its implementation. This study aims to build a more effective attendance system to answer the problems that still exist in lecture attendance. In the construction of the presence system, the use of base64 encryption repetition is used for the presence of the Qr code. QR Code is used for security and reliability in code scrambling. The randomization was intended to limit students so that they could not make attendance if the class did not match. This is done to ensure that the student is present in class and the lecturer can anticipate student fraud in taking attendance. Therefore, in order to maintain security and avoid leakage and fraud in attendance, we need a system that can protect and maintain the security of a system. Base64 encryption repetition can be used to protect each student's string.
