Screening Plagiarism

Plagiarism and Similarity Screening Policy

HEXAGON: Jurnal Ilmu dan Pendidikan Matematika is committed to maintaining academic integrity and ensuring the originality of all manuscripts published in the journal. Plagiarism, including the unattributed use of another person's words, ideas, data, or other intellectual contributions, is considered a serious violation of publication ethics.

Forms of Plagiarism

Plagiarism may occur in various forms. These include, but are not limited to:

1. Direct Plagiarism

Copying words, sentences, paragraphs, or other content from another source without appropriate quotation, acknowledgment, or citation.

2. Substantial Copying

Reproducing a substantial portion of another work without appropriate acknowledgment or permission. Substantial similarity may be assessed not only by the amount of copied material but also by the significance of the material in relation to the work as a whole.

3. Improper Paraphrasing

Rewriting or rearranging ideas, arguments, phrases, or other material from a source without appropriately acknowledging and citing the original source.

4. Self-Plagiarism and Redundant Publication

Reusing substantial portions of an author's own previously published work without appropriate citation or submitting substantially the same work to more than one publication may constitute unacceptable text recycling or redundant publication. Authors must transparently acknowledge relevant previous publications and clearly identify any legitimate reuse of previously published material.

Similarity Screening

All manuscripts submitted to HEXAGON are subject to similarity screening as part of the initial editorial evaluation and before proceeding to the peer-review process. The journal uses Turnitin to assist the editorial team in identifying textual overlap and potential issues related to originality.

The overall similarity index of a submitted manuscript must not exceed 20%. Manuscripts with a similarity index above 20% may be returned to the authors for correction and resubmission or may be rejected, depending on the nature and extent of the identified overlap.

Editorial Assessment of Similarity

The similarity percentage is used as a screening indicator and is not interpreted as evidence of plagiarism by itself. The editorial team evaluates the similarity report to determine the sources, location, nature, and significance of the identified textual overlap.

A manuscript with a similarity index below 20% may still be subject to further investigation if inappropriate copying, unattributed material, improper paraphrasing, or other forms of plagiarism are identified. Conversely, legitimate similarities arising from properly cited quotations, references, standard terminology, or other acceptable scholarly practices will be considered during the editorial assessment.

Actions on Suspected Plagiarism

If plagiarism or inappropriate textual overlap is suspected before publication, the editorial team may request clarification or revision from the authors, return the manuscript for correction, or reject the submission, depending on the severity of the issue.

If plagiarism or other significant originality concerns are identified after publication, the journal will investigate the matter and may issue a correction, retraction, or other appropriate editorial action in accordance with HEXAGON's Publication Ethics and post-publication policies.

Author Responsibility

Authors are responsible for ensuring that their manuscripts are original, that all sources are appropriately acknowledged and cited, and that previously published material is used in accordance with accepted scholarly and copyright practices. Authors are encouraged to conduct their own similarity check before submission; however, the similarity assessment conducted by the HEXAGON editorial team will be used for the journal's editorial screening process.
