NATREL (National Relationship) 2021 is a work program from the Public Relations Department of HIMA EP, Universitas Airlangga . This program was formed based on the aim that students of Development Economics, Faculty of Economics and Business Universitas Airlangga can have insight, knowledge and ability to improve good relations with related institutions and universities. This activity can also be used as a means of exchanging information, developing students' thinking patterns, reasoning power and creativity so that it can bring benefits during the lecture environment and later work environment.

On July 31 2021, HIMA EP FEB UNAIR carried out national relationship activities with KANOPI UI, or the economics student association at UI. On this auspicious occasion, Hima EP and Canopy UI again strengthened their already quite close relationship through joint activities that had been carried out previously.

On this auspicious occasion a presentation session was also held about each association so that we could exchange ideas regarding the design of each association, and be able to compare the activities and work programs carried out in each association.

Activities apart from presenting work programs and association design are also conducting focus discussion group sessions between each department or division that has the same function so that problems in each division can be identified and various understandings regarding solving problems that have been faced by each division.

This activity ended with a testimonial session on the progress of each hima and the conditions during the FGD for each division, then the activity continued with handing over mementos and taking group photos.
