J-Tektoma: Jurnal Teknik dan Teknologi Manufaktur Editorial Board recognizes that plagiarism is not acceptable and therefore establishes the following policy stating specific actions (penalties) when plagiarism is identified in an article submitted for publication.

Definition:

Plagiarism involves the "use or close imitation of the language and thoughts of another author and the representation of them as one's own original work."

Policy:

Papers must be original, unpublished, and not pending publication elsewhere. Any material taken verbatim from another source needs to be clearly identified as different from the present original text by (1) indentation, (2) use of quotation marks, and (3) identification of the source.

Any text exceeding fair use standards (herein defined as more than two or three sentences or the equivalent thereof) or any graphic material reproduced from another source requires permission from the copyright holder and, if feasible, the original author(s) and must include proper citation.

When plagiarism is identified, the Editor-in-Chief responsible for the review of this paper will decide on measures according to the extent of plagiarism detected, in agreement with the following guidelines:

Levels of Plagiarism

1. Minor: A short section of another article is plagiarized without any significant data or idea taken from the other paper.
   Action: A warning is given to the authors, and a request to change the text and properly cite the original article is made.

2. Intermediate: A significant portion of a paper is plagiarized without proper citation to the original paper.
   Action: The submitted article is rejected, and the authors are forbidden to submit further articles for one year.

3. Severe: A significant portion of a paper is plagiarized, involving the reproduction of original results or ideas from another publication.
   Action: The paper is rejected, and the authors are forbidden to submit further articles for five years.

It is understood that all authors are responsible for the content of their submitted paper as they all sign the J-Tektoma: Jurnal Teknik dan Teknologi Manufaktur Copyright Transfer Form. If a penalty is imposed for plagiarism, all authors will be subject to the same penalty.

If a second case of plagiarism by the same author(s) is identified, a decision on the measures to be enforced will be made by the Editorial Board (Editor-in-Chief and Editorial Members). The author(s) might be permanently banned from submitting further articles.

This policy also applies to material reproduced from another publication by the same author(s). If an author uses text or figures previously published, the corresponding paragraphs or figures should be identified, and the previous publication referenced. In case of a review paper or a tutorial paper, where much of the material has been previously published, the author should clearly identify the source and obtain permission from the original author and publisher.

If an author submits a manuscript to the J-Tektoma: Jurnal Teknik dan Teknologi Manufaktur with significant overlap with a manuscript submitted to another journal simultaneously, and this overlap is discovered during the review process or after the publication of both papers, the editor of the other journal will be notified, and the case will be treated as a severe plagiarism case. Significant overlap is defined as the use of identical or almost identical figures and text for half or more of the paper. For self-plagiarism of less than half but more than one-tenth of the paper, the case shall be treated as intermediate plagiarism. If self-plagiarism is confined to the methods section, it shall be considered minor plagiarism.

If an author uses some of their previously published material to clarify the presentation of new results, the previously published material shall be identified, and the difference from the present publication shall be mentioned. Permission to republish must be obtained from the copyright holder.

In the case of a manuscript originally published in conference proceedings and later submitted for publication in the J-Tektoma: Jurnal Teknik dan Teknologi Manufaktur, either in identical or expanded form, the authors must identify the name of the conference proceedings and date of publication and obtain permission from the copyright holder. The editor may decide not to accept such a paper for publication.

However, an author shall be permitted to use material from an unpublished presentation, including visual displays, in a subsequent journal publication. If a submitted publication was originally published in another language, the title, date, and journal of the original publication must be identified by the authors, and copyright permission must be obtained. The editor may accept such a translated publication to bring it to the attention of a wider audience.

The J-Tektoma: Jurnal Teknik dan Teknologi Manufaktur may also select specific previously published papers (e.g., "historic" papers) for republication to provide a better perspective on a series of studies published in one issue. Such republication shall be clearly identified as such, with proper citation of the original publication and permission from the author(s) and publisher.

The Layout Editor is responsible for maintaining the list of authors subjected to penalties and will check that no authors of a submitted paper are on this list. If a banned author is identified, the Layout Editor will inform the Editor-in-Chief, who will take appropriate measures.

This policy will be posted on the journal's website along with submission instructions, and a copy will be sent to authors with the confirmation email upon initial receipt of their manuscript. A statement will be included in the Copyright Transfer Form indicating that the author(s) have read and understood the Plagiarism Policy of the journal.
