Some of the articles in the second edition of 2020 were selected articles at the 2020 National Seminar on Physics which was held on June 20, 2020. To maintain journal quality, all Spektra journal articles have gone through a peer review process by Bestari partners and through an editing process for templates, English, and content. The main hope of this Spektra journal is to become a reliable research reference source in the field of physics and its applications.
