AKS1 Matriculation or often known as "MATRIKS" is one of the work programs of the Accounting Student Association Universitas Airlangga (UNAIR) which is implemented with the aim of introducing the Accounting Student Association and its apparatus to new students.

In 2018, MATRIKS was held again for three days, specifically on Friday-Sunday, October 26-28, 2018. This activity was held at Villa Mediana, Pacet, Mojokerto. High enthusiasm was seen from the participants and performers involved in this activity.

Starting Friday evening, all participants and committee members departed together for Pacet. Upon arrival, everyone was warmly welcomed by the MC and then invited to their respective rooms to rest.

The next day, activities began early in the morning. They gathered for preparation and breakfast. Afterward, all participants participated in an outbound activity, which was conducted in a relay of posts. This outbound activity was expected to foster team building, a sense of camaraderie, and a sense of belonging, fostering closer ties within each group. Following the outbound activity, all participants received materials on the structure of the Accounting Student Association, the Supervisory Board, the Audit Committee, and the bureaucratic process. Saturday's activities concluded with dinner and a bonding evening, which included performances from each group and an awards ceremony.

On Sunday, all participants gathered again at the pavilion to begin the activity with breakfast. This was followed by games involving all participants. The games were designed in several stages, starting with finding items, answering clues, and putting together puzzles that they had to solve together, culminating in a group photo. Then, preparations began for the return trip to Surabaya.
