Plagiarism Policy

The Editorial Board of the Indonesian Journal of Business Analytics (IJBA) firmly maintains that plagiarism is unacceptable. Therefore, the journal has established the following policy outlining specific actions and consequences when plagiarism is detected in any manuscript submitted for consideration. Plagiarism refers to the “use or close replication of another author’s words or ideas while presenting them as one’s own original work.”

Policy Overview

Submitted manuscripts must be original, unpublished, and not under review elsewhere. Any material copied verbatim from another source must be clearly distinguished from the author’s own text by using:

1. indentation,

2. quotation marks, and

3. proper citation of the original source.

Text exceeding what is considered fair use (defined here as more than two or three consecutive sentences or an equivalent amount) or any reproduced graphic content requires formal permission from the copyright holder and, when possible, the original author(s) in addition to a complete citation referencing the prior publication.

When plagiarism is detected, the Editor-in-Chief overseeing the manuscript will determine the appropriate action based on the level of plagiarism identified, following the guidelines outlined below:

Levels of Plagiarism and Corresponding Actions

1. Minor Plagiarism

Definition:
A small portion of another work is copied without significant ideas or data being taken.

Action:
The authors receive a warning and must revise the manuscript to properly cite the original source.

2. Intermediate Plagiarism

Definition:
A substantial section of the manuscript is taken from another work without proper acknowledgment.

Action:
The manuscript is rejected, and the authors are prohibited from submitting to IJBA for one year.

3. Severe Plagiarism

Definition:
A large portion of the paper is plagiarized and includes original ideas, findings, or results taken from another publication.

Action:
The manuscript is rejected, and the authors are banned from submitting to IJBA for five years. 

All authors listed on a manuscript are collectively responsible for its content, as confirmed through the IJBA Copyright Transfer Form. If a plagiarism penalty is imposed, all authors will receive the same consequence.

If an author commits plagiarism a second time, the Editorial Board (including the Editor-in-Chief and editorial members) will determine the sanction, which may include a permanent submission ban. 

Policy on Self-Plagiarism and Reuse of Previously Published Material

This policy also applies when authors reuse their own previously published material. If text or figures have appeared elsewhere, they must be clearly identified and cited. The need for such reuse is understood for review papers or tutorial-style manuscripts; however, proper attribution remains mandatory.

Authors must obtain permission from the original copyright holder for any reused content. If a manuscript submitted to IJBA significantly overlaps with one submitted simultaneously to another journal—and this overlap is discovered during peer review or after publication—it will be treated as a severe plagiarism case. Significant overlap includes identical or nearly identical figures and text covering half or more of the manuscript.

Self-plagiarism involving less than half but more than one-tenth of the manuscript is classified as intermediate plagiarism. If the overlap is restricted to the methods section, it is considered minor plagiarism.

If previously published material is reused solely to clarify new findings, the reused portions must be identified, and the differences from the earlier work must be clearly stated. Written permission must be obtained from the copyright holder.

For manuscripts previously published in conference proceedings and later submitted to IJBA either unchanged or expanded authors must disclose the conference name and publication date and secure republication permission. The editor retains the right to reject such submissions.

Authors may reuse content from unpublished presentations, including visual materials, in later journal publications. If a manuscript is a translation of a previously published work, authors must identify the original publication (title, journal, and date) and obtain the necessary copyright permissions. IJBA may accept such translations to reach a broader audience. Occasionally, the editor may choose to republish a previously published paper to provide context within an IJBA issue; this must be clearly labeled as a republication, with proper attribution and permissions.

Enforcement and Record-Keeping

The IJBA layout editor is responsible for maintaining a record of authors who have received plagiarism penalties and will verify whether any authors on new submissions appear on this list. If a banned author attempts to submit a manuscript, the layout editor will inform the Editor-in-Chief, who will take the appropriate action.

This plagiarism policy will be published on the journal’s website alongside manuscript submission guidelines and will also be sent to authors when they receive confirmation of their initial submission. A statement affirming that authors have read and understood the plagiarism policy will be added to the copyright transfer form.
