Plagiarism Policy

JURNAL KIMIA VALENSI • PUBLICATION INTEGRITY

Plagiarism Policy

Upholding originality, ethical authorship, research transparency, and the integrity of scientific evidence in chemistry and related disciplines.

Policy Statement

Jurnal Kimia VALENSI, published by the Department of Chemistry, Faculty of Science and Technology, UIN Syarif Hidayatullah Jakarta, is committed to maintaining high standards of academic integrity, scientific originality, research reliability, and ethical publication practices.

The journal considers original and unpublished research that makes a meaningful contribution to chemical sciences. Submission of a manuscript implies that the work has not been formally published elsewhere and is not under consideration by another journal or publisher.

This policy addresses plagiarism, self-plagiarism, inappropriate text recycling, data fabrication and falsification, image and spectrum manipulation, duplicate publication, misleading reporting, and related forms of scientific misconduct. Authors, reviewers, editors, and the publisher share responsibility for maintaining the accuracy and integrity of the scientific record.

1. Definition and Scope of Plagiarism

Plagiarism occurs when an individual uses another person's words, ideas, experimental methods, research data, chemical structures, figures, tables, scientific interpretations, or intellectual contributions without appropriate acknowledgment, thereby presenting them as original work.

Plagiarism may involve published or unpublished materials, including journal articles, books, theses, dissertations, conference proceedings, preprints, technical reports, laboratory records, datasets, and online sources.

Direct Plagiarism Copying text or other material from an existing source without proper quotation, acknowledgment, or citation.

Paraphrasing Plagiarism Rewriting another author's arguments, findings, or scientific explanations without acknowledging their original source.

Mosaic Plagiarism Combining sentences, expressions, or ideas from several sources without appropriate citation.

Translation Plagiarism Translating previously published content into another language and presenting it as new research without disclosure.

Self-Plagiarism Reusing substantial portions of one's previously published material without adequate citation, explanation, or disclosure.

Data and Idea Misappropriation Presenting another researcher's experimental results, datasets, chemical models, methods, or unpublished findings as one's own.

Important Principle: Proper citation is required even when an author has obtained permission to reproduce material. Permission and attribution are separate obligations.

2. Similarity Screening and Editorial Assessment

Jurnal Kimia VALENSI uses plagiarism-detection software to screen submitted manuscripts. Screening supports editorial assessment of originality and may be repeated when substantial revisions or additional verification are necessary.

Similarity Index <20% The overall manuscript similarity index must be below 20%.

The editorial assessment considers:

The overall similarity percentage and the nature of matched sources.
The extent of overlapping text in the abstract, introduction, methods, results, discussion, and conclusions.
Whether appropriate citations and acknowledgments have been provided.
Whether the overlap concerns established terminology or appropriates another researcher's distinctive analysis, data, or findings.
Whether there is substantial overlap with the authors' previously published work.
Whether the reported manuscript contains original scientific evidence and an identifiable contribution.

Manuscripts exceeding the similarity threshold may be returned for correction or major revision, or rejected when the extent and nature of the overlap constitute a serious integrity concern. Substantial overlap in the methodology, results, or discussion sections receives particular editorial scrutiny.

Similarity Is Not the Same as Plagiarism A software-generated similarity percentage does not independently establish plagiarism. Editors evaluate the relevant passages, citations, research context, and supporting evidence. A manuscript with similarity below 20% may still contain plagiarism, including misappropriated data, ideas, figures, or results.

3. Data Fabrication, Falsification, and Selective Reporting

The integrity of experimental, computational, and analytical data is fundamental to chemical research. Authors must accurately represent the research that was conducted and must not invent, modify, conceal, or selectively present evidence in a misleading manner.

3.1 Data Fabrication Fabrication refers to creating research data or observations that were never obtained through an actual experiment, measurement, calculation, or simulation.

Examples include inventing laboratory measurements, chemical yields, spectroscopy results, chromatographic peaks, computational outputs, or characterization data.

3.2 Data Falsification Falsification involves manipulating research materials, equipment settings, experimental conditions, numerical values, or recorded results so that the scientific evidence is misrepresented.

Changing reported measurements without legitimate scientific justification.
Removing outliers without explaining appropriate exclusion criteria.
Altering experimental conditions or calculations to produce preferred results.
Misrepresenting sample size, experimental replication, or analytical precision.

3.3 Selective Reporting Selective reporting occurs when researchers deliberately omit important negative, inconsistent, or contradictory findings in a manner that distorts the interpretation of the study.

Authors should report findings fairly, distinguish exploratory observations from confirmed results, and explain relevant experimental limitations.

Data Verification The Editorial Team may request supporting research records, including raw datasets, laboratory notebooks, original spectra, chromatograms, instrument outputs, computational files, or other relevant documentation when questions arise concerning authenticity or reproducibility.

4. Image, Figure, Chromatogram, and Spectrum Integrity

Scientific images and instrumental outputs are essential evidence in chemical research. Jurnal Kimia VALENSI requires authors to present these materials accurately and without alterations that could mislead readers regarding experimental observations or analytical findings.

4.1 Materials Subject to Verification

Spectroscopy
NMR, FTIR, UV-Vis, Raman, mass spectrometry, and related spectral analyses.

Chromatography
GC, GC-MS, HPLC, LC-MS, TLC documentation, and other separation analyses.

Microscopy
SEM, TEM, AFM, optical microscopy, and related material-characterization images.

Other Scientific Evidence
XRD patterns, electrophoresis images, diffraction data, micrographs, and instrumental outputs.

4.2 Prohibited Manipulation

Adding, deleting, duplicating, or altering features in scientific images without legitimate justification and disclosure.
Excessively adjusting brightness, contrast, color, or background in ways that change the scientific interpretation.
Combining images from different experiments without clearly identifying the boundaries or composite nature of the figure.
Changing peaks, intensities, baselines, or signals to create misleading spectral or chromatographic evidence.
Removing solvent peaks, impurities, or unexpected signals without an appropriate methodological explanation.
Presenting the same spectrum, chromatogram, micrograph, or image as evidence for different samples, materials, or experiments.
Reproducing previously published figures or analytical outputs without appropriate attribution and necessary permission.

Acceptable Data Processing

Scientifically justified processing, such as calibration, normalization, baseline correction, or image enhancement, must not distort the original results. Authors should describe processing procedures where relevant and retain the underlying raw data for potential verification.

5. Duplicate Publication, Redundant Research, and Salami Slicing

Duplicate or redundant publication occurs when substantially the same research is submitted or published more than once without adequate disclosure, citation, or legitimate scientific justification.

Unacceptable practices include:

Submitting the same or substantially similar manuscript to multiple journals simultaneously.
Republishing substantially identical findings under a different title or authorship arrangement.
Reusing the same dataset with only superficial changes to the analysis or presentation.
Dividing one coherent research project into multiple minimally differentiated publications without a substantial independent contribution, commonly referred to as salami slicing.
Reusing previously published figures, tables, or experimental findings without acknowledgment.

Extended or Related Research A manuscript developed from previously published work must clearly identify the earlier publication, describe the additional experiments or analyses, and demonstrate the substantive novelty of the new contribution.

A previously published conference abstract may be disclosed as an earlier version when the submitted article provides substantial new evidence or analysis and otherwise meets the journal's originality requirements.

6. Preprint Policy

Jurnal Kimia VALENSI permits authors to share their Author's Original Manuscript (AOM) on non-commercial preprint platforms before submission or during peer review, subject to the journal's requirements concerning disclosure and copyright.

Examples of preprint platforms may include ChemRxiv, arXiv, HAL, and other relevant non-commercial repositories.

Authors must ensure that:

The preprint server allows authors to retain the necessary rights to their manuscript.
The existence of the preprint is disclosed during journal submission.
The preprint is appropriately identified and cited where relevant.
The submitted manuscript is not simultaneously under editorial review by another journal.
After publication, the preprint record is updated, where possible, with the citation and link to the final published article.

A disclosed preprint is distinguished from formal journal publication. However, previously published journal articles or manuscripts undergoing active review by another publisher are not eligible for simultaneous consideration by Jurnal Kimia VALENSI.

7. Authorship Ethics and Responsible Use of AI

7.1 Responsible Authorship

All authors must make a substantial contribution to the research, participate appropriately in manuscript preparation or critical revision, approve the final version, and accept responsibility for the integrity of the work.

Guest, gift, honorary, ghost, or otherwise misleading authorship is unacceptable.
Author contributions must be accurately represented.
Technical assistance and other contributions that do not qualify for authorship should be acknowledged appropriately.
All co-authors must approve the manuscript before submission.

7.2 Generative AI and Plagiarism Prevention

Generative AI or AI-assisted writing technologies must not be used to conceal plagiarism, fabricate references, invent experimental data, or misrepresent scientific findings. Authors remain responsible for verifying the originality, accuracy, and attribution of all manuscript content.

In accordance with the journal's policy, the use of generative AI for scientific writing must be disclosed. Such tools may assist readability and language quality under human supervision but must not be listed as authors or co-authors.

8. Editorial Procedures for Suspected Misconduct

Jurnal Kimia VALENSI evaluates credible allegations of plagiarism and related scientific misconduct through an evidence-based process informed by the Committee on Publication Ethics (COPE). An allegation does not, by itself, establish wrongdoing.

8.1 Initial Assessment

The Editorial Team reviews the suspected overlap or integrity concern.
Relevant materials and documentary evidence are examined.
The corresponding author may be contacted to provide clarification.
Additional supporting data, original spectra, laboratory records, or instrument outputs may be requested.
Qualified experts may be consulted when specialized scientific assessment is necessary.
The Editorial Team determines an appropriate response according to the available evidence.

8.2 Classification and Editorial Action

Minor Attribution Problems Limited citation, quotation, or acknowledgment errors that do not involve substantial misappropriation of original findings or scientific data.

Possible editorial action: Request for clarification, correction, or manuscript revision.

Substantial Unattributed Overlap Significant unattributed reuse of text, scientific arguments, methods, research data, or findings that compromises the manuscript's originality.

Possible editorial action: Major revision when a legitimate remedy is possible, or rejection when the violation is substantiated and materially affects the work.

Serious Scientific Misconduct Extensive plagiarism, deliberate data fabrication or falsification, deceptive manipulation of experimental evidence, or other serious violations affecting the reliability of the research.

Possible editorial action: Rejection, referral to the relevant institution when appropriate, or further action under the journal's research-misconduct procedures.

The classification and response are determined by the facts of each case. Editorial action should be fair, proportionate, documented, and consistent with the journal's publication-ethics policies.

9. Misconduct Identified After Publication

Concerns about plagiarism, duplicated research, unreliable scientific evidence, or other integrity problems may arise after an article has been published. Such concerns will be assessed using available evidence and appropriate editorial procedures.

Correction A correction may be issued when an error or attribution problem can be remedied without invalidating the article's central conclusions.

Expression of Concern An editorial notice may be considered when serious unresolved questions remain concerning the reliability or integrity of a published article.

Retraction Retraction may be necessary when substantiated plagiarism, fabrication, falsification, or another serious problem makes the published findings or scholarly record unreliable.

Institutional Referral Research institutions or relevant authorities may be contacted when allegations require formal investigation beyond the journal's editorial responsibilities.

Purpose of Post-Publication Action

Corrections, Expressions of Concern, and retractions are mechanisms for preserving the integrity and transparency of the published scientific record. Their use depends on the seriousness of the problem and its effect on the reliability of the article.
