Senior High School 1 V Koto Timur is one of the public schools located in Padang Pariaman Regency. In solving student problems, schools have guidance and counseling teachers that are responsible for providing services to students, whether students have problems or commit violations. But in fact, the existing counseling guidance has not been properly recorded related to the guidance and violations committed by students. With the development of a counseling guidance application, it is hoped that it can be a solution to these to monitor guidance counseling or violations committed by students. This study aims to develop a counseling guidance application that can mediate interactions between teachers and students as well as monitor student progress by their parents. The counseling guidance application was developed using the waterfall method, where each stage is carried out sequentially. It was developed using the CodeIgniter 3 framework of data management, the counseling guidance application utilizes the PHP programming language, MySQL database, and Apache web server. Based on the research that has been done, it can be concluded that this counseling guidance application can be an intermediary for interaction between teachers and students, especially at SMA N 1 V Koto Timur, with an activity log that stores counseling guidance data between teachers, BK teachers, homeroom teachers, and students. In addition, parents can also monitor developments related to violations, guidance, and achievements of their children at school.
