National Relationship 2021 is an annual mandatory event for HIMA EP UNAIR, particularly the Public Relations Department. This activity aims to strengthen HIMA EP UNAIR's relationships with various institutions outside the campus. The event aims to compare programs, strengthen collaboration between associations, and enhance the associations' branding.

On November 27, 2021, HIMA EP UNAIR successfully carried out national relationship activities with BEST Prasetiya Mulya, which is the association of business economics majors at Prasetiya Mulya University.

On this occasion, various designs, work programs, management structures, and various advantages of each association were also presented. This was to compare the associations on a macro level so that the specifications of each association could be known

This was followed by FGD activities with each division having the same specifications. From this, it was known that the composition of BEST PRASMUL was very slim compared to the EP UNAIR student association, because in PRASMUL itself, there were very few students majoring in business economics compared to EP UNAIR 

This FGD activity also aims to identify the strengths and weaknesses of each division in carrying out an activity, how the division survives amidst the pandemic, and also share problems that often occur in each division.

At the end of the activity, FGD testimonials and impressions were also given, then closed with a group photo.
