About the Journal

Marlajar: Journal of Science, Technology, and Innovation is an international scientific journal dedicated to publishing original, peer-reviewed research articles in the fields of science, technology, and innovation. The word “Marlajar” comes from the Simalungun Batak language and means “belajar” or “berlatih.” Scientifically, it refers to the active process of building knowledge through the scientific method, which involves observation, experimentation, and communication. This journal accepts manuscripts covering a wide range of topics, including natural and applied sciences, engineering and technology, information and communication technology, industrial innovation, renewable energy, and environmental studies. Submitted manuscripts will be reviewed by the journal’s editorial board. All submitted articles must present original research findings that have not been previously published and will undergo a peer-review process. Articles submitted to this journal must meet these criteria and must not be under consideration for publication elsewhere. Manuscripts must adhere to the journal’s style guidelines and will undergo a peer-review process as well as editorial editing. Marlajar is published twice a year in February and August, promoting innovative, sustainable, and forward-looking contributions that support scientific progress and technological development at both the national and international levels.
