About the Journal

Dear Presenters, Participants, Authors, and Reviewers,

We are pleased to announce the publication opportunity at JCU: Journal CASTLE KPM UNJ. This journal is specifically dedicated as one of the official outputs for the 5th CASTLE (Conference of Social, Science, Technology, Language, and Education Research).

JCU aims to serve as a platform for disseminating high-quality findings in education research fields presented at the 5th CASTLE conference. This provides a valuable opportunity for presenters to publish their work in a scholarly journal.

The success of this conference and the launch of JCU have been made possible through the support of many parties. We extend our sincere gratitude to the Institute for Research and Community Service (LPPM) UNJ and the UNJ Student Affairs office, particularly Mr. Taryudi, Mr. Firmanul Catur Wibowo, and Mrs. Widyaningrum Indrasari.

We also extend our gratitude to the alumni, fellow journal editors, and the 2025 Research Institute of Kelompok Peneliti Muda (KPM) UNJ. We are especially grateful to the Public Relations (HIK) and Research (P2P) divisions, particularly Nida Eka Safitri, Muhamad Hafiz, and Muhammad Farid for their efforts in coordinating this journal.

Once again, thank you for your continued support and collaboration in the dissemination of scientific knowledge.

Best regards,
