Plagiarism

Plagiarism Policy

All manuscripts submitted to the Jurnal Ilmu Pendidikan Matematika Indonesia (MATEDO) will be screened for plagiarism and academic misconduct. MATEDO maintains a strict policy against plagiarism and self-plagiarism to ensure the originality and integrity of all published scientific works. Any manuscript found to contain plagiarism or significant self-plagiarism may be rejected by the editorial team.

Before being forwarded to reviewers, all submitted manuscripts undergo an initial similarity check conducted by the editorial team using Turnitin or other recognized plagiarism-detection software. Manuscripts submitted to MATEDO must have a similarity index of less than 25%, excluding references/bibliography, and the similarity score from any single source should not exceed 1%.

Definition of Plagiarism

Plagiarism is the act of using another person's ideas, words, data, findings, or intellectual work without proper acknowledgment, citation, or permission and presenting them as one's own. Plagiarism may occur intentionally or unintentionally and can take several forms, including direct copying, substantial copying, and paraphrasing without appropriate attribution.

Literal Copying

Literal copying occurs when an author reproduces another author's work word-for-word, either partially or entirely, without appropriate acknowledgment, citation, or permission where required.

Substantial Copying

Substantial copying occurs when an author reproduces a significant portion of another person's work without proper acknowledgment or citation. The significance of the copied material may be assessed based on both its quantity and its substantive contribution to the original work.

Paraphrasing

Paraphrasing involves expressing another person's ideas, concepts, arguments, or findings using different words while retaining the original meaning. Paraphrased material must still be properly cited. Failure to acknowledge the original source constitutes plagiarism.

Forms of Plagiarism Include, but Are Not Limited To:

  1. Copying terms, words, sentences, data, tables, figures, or other information from a source without proper citation.

  2. Using quotations from a source without clearly acknowledging and citing the original source.

  3. Using ideas, opinions, concepts, hypotheses, theories, or arguments from another source without appropriate acknowledgment.

  4. Rewriting or paraphrasing another author's work without providing appropriate references.

  5. Submitting research, manuscripts, or scientific works created wholly or partially by another individual as one's own work.

  6. Self-plagiarism, including the substantial reuse of previously published material without appropriate citation, disclosure, or justification.

Prevention

The Jurnal Ilmu Pendidikan Matematika Indonesia (MATEDO) is committed to maintaining high standards of academic integrity and ensuring that all published articles are original and properly attributed.
