Hutasoit, Josua, Rohmatulloh, Vanda, Putantri, Nazlah Sari, Efrizoni, Lusiana
Abstract:   Abstract: Student attendance is one of the activities carried out in the lecture process. Attendance is also an element of a student's final grade for each course offered in accordance with a university's academic guidelines.… idelines. Attendance at STMIK Amik Riau is done manually, where students are called one by one and then the lecturer changes the attendance data in SIMDOS. This method is of course very inefficient, and takes a long time. Apart from that, this manual process is prone to fraud where students can make absences. Therefore, this research proposes a QR-Code based student attendance mobile application prototype at STMIK Amik Riau using the User Centered Design (UCD) method. The results of the research are in the form of a prototype or user interface design for the student attendance mobile application. It is hoped that this prototype can help programmers to build QR-Code based student attendance mobile applications. Keywords: Presence, QR-Code, User Interface, User Centered Design   = Abstrak: Kehadiran atau presensi mahasiswa merupakan salah satu kegiatan yang dilakukan dalam proses perkuliahan. Presensi juga merupakan salah satu elemen nilai akhir mahasiswa setiap mata kuliah yang ditawarkan sesuai dengan panduan akademik suatu perguruan tinggi.

Amin, Muhammad, Supriyanto, Boby, Tamaza, Muhammad Abyanda, Asy’ari, Ilham, Fadillah, Riszki
Abstract: Student development includes conduct as a key component. Student behavior becomes crucial in deciding how successful students will be in different spheres of life. The variety of student behavior can hinder the learning… process and personal development of students. Through the development of an expert system-based counseling model based on backward chaining, this study seeks to discover trends in student behavior. The research process starts with problem analysis, goal setting, literature study, data collection, system design and implementation, and results analysis. It then moves on to counseling model development and implementation in the school setting. To determine the reasons for the unruly behavior of the kids, data were analyzed using a backward chaining methodology. UML Usecase diagrams are used in system design to define the roles of actors and users. The established counseling model, which consists of 14 behaviors, 67 phenomena/symptoms, and 14 rules, focuses on goals and methods to modify student behavior. Three students underwent system testing based on previously achieved goals from therapy. The findings revealed "Smoking," "Emotional Problems," and "Fighting" among the student behaviors. When the Backward Chaining-based counseling model is used, it is simpler for homeroom teachers to gather information about students' conduct from them and to offer remedies based on the transfer of professional knowledge without having to wait for the counselor guidance procedure
