We are informing you that there has been a change of server for the journal's website. As a result, all current submissions will need to be resubmitted to the new website.

Please note that the old website (http://efi.ui.ac.id) is no longer in use. We apologize for any inconvenience this may have caused, but we are pleased to announce that the transition to the new server is now complete.

In the future, please use the new website (https://scholarhub.ui.ac.id/efi/) to submit any new papers or to check the status of your current submission.

Thank you for your patience and understanding during this transition period. We look forward to receiving your submissions on the new website.
