National Relationship 2021 is an annual mandatory agenda for HIMA EP UNAIR, especially the public relations department, where this activity aims to improve Hima EP UNAIR's relations with various other institutions outside campus. This activity aims to compare the activity programs carried out, apart from that, it also strengthens cooperative relations between associations, as well as improving the branding of the association itself.

On November 27 2021, HIMA EP UNAIR has successfully carried out national relationship activities with BEST Prasetiya Mulya, namely the business economics department association at Prasetya Mulya University.

On this occasion, various designs, work programs, management composition and various advantages of each association were also presented. This was to carry out a macro comparison of the associations so that we could find out what the specifications of each association were.

Next followed by FGD activities with each division which has the same specifications, from this it is known that the composition of BEST PRASMUL is very slim compared to Hima EP UNAIR, because at PRASMUL itself there are very few students majoring in business economics compared to EP UNAIR 

This FGD activity also aims to find out the strengths and weaknesses of each division in carrying out an activity, how the division survives in the midst of a pandemic, as well as sharing problems that often occur in each division.

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