Plagiarism Checker
Plagiarism Checker
The Journal of JAFA recommends Turnitin for manuscript similarity screening. This page explains our purpose, policy, and how to conduct a pre-check before submission.
All submissions to JAFA undergo a similarity screening. Authors are encouraged to run a personal pre-check to help expedite editorial processing.
1. Statement & Purpose
The integrity of scholarly publishing relies on academic honesty. JAFA conducts similarity checks to prevent plagiarism, duplicate publication, excessive text recycling, and other unethical practices.
2. Why Similarity Checking Matters
- Safeguards the reputation of the journal and authors against ethics breaches.
- Promotes originality and scholarly integrity.
- Speeds up peer review by reducing administrative revisions.
3. Recommended Tool: Turnitin
Turnitin is a widely used similarity-detection platform for education and research. It compares manuscripts against an extensive database (scholarly articles, assignments, the web, etc.) and generates a Similarity Report that highlights matched passages and their sources.
Beyond detection, Turnitin supports writing development via feedback and annotation features. It is therefore a key tool to uphold academic integrity and encourage original work.
4. Author Pre-check (Before Submission)
- Use the JAFA .docx template and follow the Author Guidelines.
- Run a pre-check using your institutional/class Turnitin account. For pre-checks, choose “no repository” or settings that do not store your draft in a permanent repository.
- Enable Exclude bibliography and Exclude quotes (see settings below).
- Fix flagged passages: add proper quotations and citations, perform substantive paraphrasing, and credit sources.
- Upload the final manuscript to OJS. The Editorial Office will conduct the official check (Turnitin/iThenticate).
5. JAFA Similarity Threshold Policy
- Overall similarity ≤ 20% (after excluding bibliography & quotations).
- A single large block from one source (e.g., > 5%) may warrant rejection, even if the total is ≤ 20%.
- Duplicate publication, excessive text recycling, or inadequate attribution will be rejected.
6. Suggested Report Settings
| Setting | Recommendation | Notes |
|---|---|---|
| Submission storage | No repository (for author pre-check) | Prevents permanent storage of drafts. |
| Exclude bibliography | On | Avoids inflated similarity from references. |
| Exclude quotes | On | Quoted text must still be properly cited. |
| Exclude small matches | On (≥ 8–10 words) | Reduces false positives from common phrases. |
7. Writing Ethics & Tips to Avoid Plagiarism
- Write in your own words—understand concepts before paraphrasing.
- Always cite sources when using others’ ideas or text.
- Use a reference manager (Zotero/Mendeley/EndNote) for consistency.
- For your prior work, avoid self-plagiarism—explain relationships and cross-cite appropriately.
- Follow JAFA’s Publication Ethics.
8. Frequently Asked Questions (FAQ)
- Does a high percentage automatically mean plagiarism?
No. The percentage is only an indicator. Editors evaluate the context and nature of matches. - Why is my percentage high when I use many quotations?
Ensure Exclude bibliography & Exclude quotes are enabled; cite properly and consistently. - What if my result exceeds 20%?
Revise problematic sections—perform substantive paraphrasing, add correct citations, then re-check before resubmitting. - Can Turnitin screen Indonesian manuscripts?
Yes. Turnitin is multilingual. Use your selected citation style correctly (e.g., APA 7th).
