Author Guidelines

Instructions for preparing rigorous, reproducible, ethically responsible, and original contributions to chemical sciences.

Before You Submit

Jurnal Kimia VALENSI, published by the Department of Chemistry, Faculty of Science and Technology, UIN Syarif Hidayatullah Jakarta, welcomes significant and original contributions to theoretical, experimental, and applied chemistry. Authors should consult the Focus and Scope before preparing a manuscript.

A suitable manuscript must clearly explain the research problem, review the relevant state of the art, identify its research gap and novelty, employ appropriate and transparent methods, present verifiable findings, and discuss its specific contribution to chemical knowledge. All submissions must use the official journal template and comply with applicable editorial and publication-ethics policies.

Key Manuscript Requirements

For detailed formatting and examples, authors must follow the latest official Jurnal Kimia VALENSI manuscript template.

Submissions must be original, unpublished, within the journal's scope, and not under consideration by another journal. The journal accepts manuscripts in English or Bahasa Indonesia, with English strongly preferred. Manuscripts written in Indonesian must still provide the required English title, abstract, and keywords in accordance with the journal template.

2.1 Title, Authors, and Affiliations

The title must be concise, informative, scientifically accurate, and no longer than 20 words. It should indicate the essential subject or important finding, avoid unnecessary abbreviations, and be written in clear English.

List authors by their full names without academic titles. Use superscript numbers to connect authors with affiliations and an asterisk to identify the corresponding author. Provide the corresponding author's email address. Author order and contribution must be approved by all co-authors; metadata must be consistent across the manuscript, OJS record, and published article.

2.2 Abstract and Keywords

Provide an English abstract of no more than 200 words, in Times New Roman 10 pt, single-spaced. It should be intelligible without consulting the full paper and normally present the following information in a coherent paragraph:

1. Context and problem: The scientific issue and why it matters.
2. Objective: The specific purpose of the study.
3. Methods: The central experimental, computational, or analytical approach.
4. Principal results: Key findings, preferably with quantitative evidence where relevant.
5. Conclusion: The principal interpretation and contribution to the field.

Do not include citations, figures, tables, equations, or unexplained abbreviations. Provide 3–5 keywords in English, arranged alphabetically, specific enough for scholarly indexing, and separated consistently as required by the template.

2.3 Introduction

Establish the scientific background and significance of the research problem using relevant primary literature. Critically synthesize earlier findings and identify the current state of the art rather than listing previous studies one by one.

Explain the unresolved problem, limitation, or research gap, and justify the novelty and scientific contribution of the work. Define the research objectives, research questions, or hypotheses explicitly toward the end of the Introduction. A new sample, location, or material alone does not establish novelty unless it yields a substantive scientific contribution.

2.4 Research Methods / Materials and Methods

Describe the research so that other researchers can evaluate, reproduce, or independently verify the work. Where applicable, report:

1. Materials: Chemical names, purity or grade, sources, reagents, solvents, biological materials, and relevant sample characteristics.
2. Equipment and instrumentation: Instrument type, manufacturer/model where pertinent, operating conditions, calibration, and measurement settings.
3. Research design: Experimental groups, controls, computational models, variables, replication, and sampling approach, as relevant.
4. Procedures: Sufficient synthesis, extraction, preparation, characterization, analytical, or simulation details, including quantities, time, and temperature.
5. Data processing: Calculations, statistical tests, uncertainty measures, software and versions where relevant, and criteria for interpreting results.
6. Reliability: Method validation, accuracy, precision, detection limits, recovery, or other appropriate quality-control criteria.

Cite established methods and explain any modifications. Do not claim measurements, experiments, statistical procedures, or characterization analyses that were not actually performed. For human or animal intervention studies, provide the relevant ethical-clearance documentation.

2.5 Results and Discussion

Present the Results and Discussion as one integrated main section, with informative subheadings if needed. Results must be accurate and supported by verifiable experimental data, computational output, spectra, chromatograms, images, measurements, or other relevant evidence.

Explain the meaning of the findings through chemical principles and appropriate theory, identify mechanisms and relationships where the evidence permits, and compare the results critically with previous research. Address consistency and differences with published studies, explain unexpected results, and avoid repeating table or figure content verbatim.

Emphasize the scientific advancement and the boundaries of the claims. Report relevant variability, uncertainty, limitations, and reproducibility issues. Interpretations and conclusions must not extend beyond the available data.

2.6 Conclusions

Provide a concise synthesis that directly addresses the research objectives, explains the most important scientific findings, and identifies the study's original contribution or practical implications. Conclusions should be written as paragraphs, not merely a list of results. Avoid introducing new findings, unsupported claims, or a repetition of the abstract. Indicate focused directions for future work when justified.

2.7 Acknowledgments and Declarations

After the Conclusions and before References, include the relevant statements below. All declarations must be accurate, specific, and consistent with the submission metadata.

• Figures: Supply readable photographs, chemical structures, schemes, spectra, chromatograms, microscopy images, graphs, and other illustrations at a minimum of 300 dpi. Number figures consecutively and place them near their first discussion.
• Figure captions: Place explanatory captions below each figure, using sentence case; identify the figure number and explain necessary abbreviations, symbols, or experimental conditions.
• Tables: Place titles above tables; use horizontal rules for the heading and bottom border, avoid unnecessary vertical rules, and add explanatory footnotes when needed.
• Equations and symbols: Define variables and symbols; italicize mathematical variables where appropriate and number displayed equations consistently. Use accepted chemical notation and SI units.
• Data integrity: Do not alter peaks, spectra, backgrounds, micrographs, or images in ways that misrepresent the original results. Disclose any permissible image processing and retain raw records for potential editorial verification.
• Supplementary materials: Provide additional spectra, datasets, instrument outputs, procedures, or supporting analyses when these improve transparency and reproducibility. Refer clearly to all supplementary files in the manuscript.
• Permissions: Obtain necessary permission and attribution for third-party figures, photographs, or other copyrighted material.

Use the American Medical Association (AMA) citation and reference style consistently in the text and the reference list. In-text references should be numbered in order of first citation, using the numerical format demonstrated by the official journal template. Do not switch to an author-date system.

• Provide at least 20 relevant references.
• At least 80% should be journal articles; prioritize original research as primary sources rather than relying mainly on secondary reviews.
• At least 80% should have been published within the preceding 10 years, while important foundational studies may be included when relevant.
• Use references to establish the state of the art, research gap, theoretical basis, analytical methods, and critical comparison of findings.
• Verify author names, publication years, journal titles, volume, issue, pages or article numbers, and DOI details.
• Include only works cited in the manuscript, and cite all sources used. Prefer DOI identifiers where available and use Zotero, Mendeley, EndNote, or an equivalent reference manager.

Jurnal Kimia VALENSI evaluates manuscripts for originality, scientific contribution, methodological reliability, research ethics, and compliance with its focus and scope. Submissions are screened for similarity and may be examined for plagiarism, redundant publication, fabricated data, undisclosed conflicts, image manipulation, or other misconduct.

Similarity screening: The journal's published Plagiarism Policy specifies an overall similarity index below 20%. Similarity reports are interpreted alongside substantive editorial checks; a low percentage does not guarantee originality or acceptance.

Peer review: Manuscripts that pass the initial editorial assessment undergo double-blind peer review by at least two qualified experts, as stated in the journal's current review policy. Reviewers assess scientific novelty, analytical rigor, evidence, interpretation, presentation, and scholarly significance.

Anonymous review: If the editorial workflow requests a blinded manuscript, remove author names and identifying acknowledgments from the review file, but provide complete author details separately through OJS and the required title-page file.

Revisions: Authors must address reviewer and editor comments substantively and provide a point-by-point response, highlighting the corresponding changes. Resubmissions should be completed by the stated deadline.

Editorial decisions: Acceptance is not guaranteed by passing similarity checks, completing revisions, or paying an article processing charge. The editorial decision is based on scholarly merit and the completed peer-review process.

Manuscripts must be submitted through the VALENSI online submission system. Authors must register or sign in, complete all required manuscript metadata, and upload the manuscript and supporting documents.
