System Recovery Notice
The Open Journal Systems (OJS) platform used by Jurnal Tadris Matematika previously experienced a malware attack that affected the journal system and resulted in the partial loss of historical data. Following the incident, system cleaning, service restoration, data verification, and reconstruction of verifiable publication archives and available editorial records were undertaken.
The affected issues of Jurnal Tadris Matematika are:
- Volume 8, Issue 1, June 2025
- Volume 8, Issue 2, November 2025
- Volume 9, Issue 1, June 2026
As a consequence of the recovery and reconstruction process, some dates displayed in the OJS workflow history for articles published in these issues may not fully represent the original editorial chronology prior to the incident.
