SINERGI
Initially, the Board of Trustees of PPPK Petra published Sinergi Magazine as a means of information and communication between the board of trustees and the entire PPPK Petra community. Since May 2004, the board of trustees changed the format of Sinergi Magazine to Sinergi Tabloid to make it more communicative. Sinergi Tabloid is published twice a year and contains information about the PPPK Petra organization.
