Article Processing Charges (APCs)

SPEKTRA publishes all articles in a fully open access format, ensuring that the scientific community and the general public have free, unlimited, and immediate access to all content as soon as it is published online. This aligns with the principles of the Budapest Open Access Initiative.

SPEKTRA does not generate income from selling subscriptions, charging "pay-per-view" fees, or restricting access to its articles. To cover the costs associated with editorial processes, peer review, production, and online hosting, SPEKTRA collects an Article Processing Charge (APC).

• APC Details:
  • The APC is USD 120.00 or the equivalent of IDR 1,500,000.00.
  • APCs are only payable once an article has successfully passed peer review and has been accepted for publication.
  • Submission to SPEKTRA is free of charge, and no fees are incurred during the initial submission or review process.

SPEKTRA is committed to transparency in all author charges:

• No hidden charges: Authors are not required to pay submission fees, editorial processing fees, page charges, or color charges.
• Fee waivers: Authors who are unable to pay the APC may request a waiver. Waivers are considered on a case-by-case basis and must include details such as the reason for the request and the time period for which the waiver applies.

This approach ensures that SPEKTRA maintains a high standard of scholarly publishing while remaining accessible and inclusive for authors worldwide.
