This service activity aims at building an advanced and integrated library system between one library and another within the Faculty of Social and Political Sciences, Mulawarman University (Fisip Unmul) so that the existing libraries are not outdated. The methods used to implement it are through mentoring, workshop-training, as well as monitoring and evaluation. There are 9 partners for this activity, consisting of two Faculty website admins/technicians, three Faculty library operators, two library operators for the Master of Public Administration (MAP) program, and two library operators for the undergraduate study program of Integrative Government (PIN). The result of this activity is that the latest library system has been developed where the three libraries in question have been successfully integrated and are fully functioning/operating (100% realization), so that much progress has been achieved in library management with the new system compared to the old one in terms of work efficiency, the number of digital collections and their access systems, as well as synergy between libraries. Apart from that, the skills of partners in building integrated libraries increased by an average of 77.22% in implementing this activity.
