The publication ethics of the Journal of Philology and Historical Review refer to COPE (Committee on Publication Ethics).

This scientific code of ethics statement is a statement of the code of ethics of all parties involved in the publication process of this scientific journal, namely managers, editors, reviewers, and authors. This scientific publication code of ethics statement is based on the Regulation of the Head of the Indonesian Institute of Sciences Number 5 of 2014 concerning the Code of Ethics for Scientific Publications, which in essence upholds three ethical values in publication, namely:

1. Neutrality, which is free from conflicts of interest in the management of publications;
2. Fairness, which is giving authorship rights to those who are entitled as authors; and
3. Honesty, which is free from duplication, fabrication, falsification, and plagiarism (DF2P) in publications.

Author Duties

Reporting Standards: The author must present an accurate report of the research conducted as well as important points of discussion that are objective in nature. The researcher must present the results of his/her research honestly and without imitation, falsification or inappropriate manipulation of data. A scientific paper should contain enough detailed information and bibliography to allow other researchers to continue their research. Fraudulent or deliberately inaccurate reporting is unethical and unacceptable behavior. Manuscripts must follow the journal submission guidelines.
Originality and Plagiarism: Authors must ensure that their work is entirely original. Authors cannot submit a manuscript to more than one journal publication simultaneously unless it has been approved by the editors. Previous similar papers and publications, either by other researchers or the authors themselves, may be acknowledged and referenced. If any primary literature is used, it should be cited. If a statement is taken directly from another researcher's publication, it should be marked with the word quote.
Excessive publication at the same time: in general, authors should not submit the same manuscript to more than one journal published at the same time. This is to avoid unethical and unacceptable behavior.
Diverse publications arising from personal research should be properly identified and their results referenced.
Acknowledgment of Sources used: Authors should acknowledge all sources of data used in the research and cited publications that have been influential in determining the nature of the research. It is always a good idea to give proper acknowledgment to other people's research.
Ownership: Ownership of published research should accurately reflect each individual's contribution to the paper and its report. Ownership should be limited to researchers who made significant contributions to the concept, design and interpretation of the study. Other researchers who contributed equally should be listed as second, third, and so on. When the most contributors are listed as the first author, the other contributors should be listed in the acknowledgment section. Authors should ensure that all contributors have seen and approved the paper for publication and their involvement as second, third, and subsequent authors.
Disclosure and Conflicts of Interest: All authors must disclose their manuscripts with regard to both financial matters and conflicts of interest that may have a limiting influence on the interpretation of the manuscript. All financial sources/funds supporting all projects should be disclosed.
Fundamental Errors in Published journals: If the author discovers fundamental errors or inaccuracies in the submitted manuscript, the author should heed the advice of the journal editor or publisher and work with the editor to improve the paper.
Hazards, People and Animation: Authors should clearly identify hazards in their manuscript such as chemicals, procedures, and equipment used.

Editor Duties

Publishing Decision: Based on the review of the board report, the editors may accept, reject, or request changes to the manuscript. The validity of the work and its importance to researchers and readers should always drive the decision. The editors may be guided by the policies of the journal's editorial board and limited by legal requirements such as those applicable to libel, copyright infringement and plagiarism. Editors may confer with other editors or reviewers in making these decisions. Editors should be responsible for everything they publish and should have procedures and policies in place to ensure the quality of the material they publish and maintain the integrity of published papers.
Manuscript Review: Editors should ensure that each manuscript is initially evaluated by the editors for originality. The editor should organize and use peer review that is capable and thoughtful. In addition, he or she should explain the peer review process to the authors and indicate which parts of the journal were reviewed. The editor should also use the right peer reviewers for papers that are worthy of publication by selecting people with sufficient competence and avoiding conflicts of interest.
Fairness: The editor must ensure that every manuscript received by the journal's editorial board is reviewed for intellectual content regardless of the author's gender, race, religion, nationality, etc. An important part of his or her responsibility is to make decisions that are fair and contain the enforcement of the principles of editorial independence and integrity. Editors are in a powerful position by making publishing decisions, which makes it very important that this process is as fair and objective as possible.
Confidentiality: Editors must ensure that information regarding manuscripts submitted by authors is kept confidential. Editors should critically assess any potential breach of data protection and author confidentiality, including using appropriate information related to the current research presented, and research that is applicable and worthy of publication.
Disclosure and Conflicts of Interest: Journal Editors will not use unpublished material disclosed in a submitted manuscript for their own research without the written consent of the author. Editors should not be involved in decisions about which papers have conflicts of interest.

Reviewer Duties

Confidentiality: Information regarding manuscripts submitted by authors should be kept confidential and treated as confidential information. They should not be shown or discussed with others except as authorized by the editor.
Acknowledged Sources: The reviewers should ensure that the authors have acknowledged all sources of data used in the paper. He/she should also identify relevant published papers not cited by the authors. Some statements that observations, derivations, or opinions have been previously reported should be accompanied by relevant citations. Reviewers should inform the editorial board of the journal as soon as possible if they commit any irregularities, such as work ethics, become aware of substantial similarities between the manuscript they are reviewing and a manuscript submitted to the journal or another published article, or suspect that this may have occurred either during the research or the writing and submission of the manuscript; reviewers should, however, maintain author confidentiality and not investigate further unless the editorial board of the journal requests further information or advice.
Objectivity Standard: Reviews of submitted manuscripts should be conducted objectively and the reviewer should express his/her views with clear and supportive arguments. He/she should also follow the journal's instructions regarding the specific feedback required by the author, unless there are reasonable grounds for not following them. The reviewer should be constructive in his/her review and provide feedback that will help the author to improve the quality of the author's manuscript, providing suggestions and feedback that can support the statements made in the manuscript in consideration of how it can improve the quality of the author's writing.
Disclosure and Conflict of Interest: Privileged information or ideas obtained through peer review must be kept confidential and not used for personal gain. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers. In the case of double-blind review, if they suspect the identity of the author(s) notify the journal if this knowledge raises any potential conflict of interest.
Confidential information or ideas obtained through peer review must be kept confidential and not used for personal gain.

Ketepatan: Pengulas harus memberikan respon dalam kerangka waktu yang disepakati. Ia hanya setuju untuk meninjau/mengulas naskah jika mereka cukup yakin mereka dapat menyampaikan hasil ulasannya dalam waktu yang disepakati bersama, menginformasikan jurnal sesegera mungkin jika mereka memerlukan penambahan waktu. Bilamana ia merasa tidak mungkin untuk menyelesaikan ulasan naskahnya dalam waktu yang ditentukan, maka informasi ini harus dikomunikasikan kepada editor, sehingga naskah bisa dikirim ke pengulas lain.[]
