One of the services of HIMAINFRA is to distribute announcements and upcoming events to the students.Nowadays, HIMAINFRA uses posters and social media, such as LINE and Instagram, to distribute the announcements and information to the students.

Besides that, to register as an event participant or an event committee, the student still need to do it manually (i.e., paper-based).This Android-based HIMAINFRA application was developed to help HIMAINFRA distribute the announcements and information. This application also helps HIMAINFRA’s members on running a committee and enables the students of the Department of Informatics and Business Information System to register online as event participants or committees.
