Finding academic journals is not just typing a topic into a search engine. The trick is to separate three different tasks, then pick the right database and the right way to judge quality. This guide uses four main sources, two of them Indonesia-specific: Garuda, SINTA, Google Scholar, and DOAJ.

Reviewed July 2026 against the Garuda and SINTA portals (run by Indonesia’s Ministry of Higher Education, Science, and Technology, “Kemendiktisaintek”), Google Scholar, and DOAJ. Interfaces and features can change.

Three tasks people confuse

Finding papers to read and cite.
Evaluating a journal — is it credible, indexed, worth citing?
Finding a venue to publish your own work.

They use similar tools for different ends. Mixing them up is how people cite a predatory journal or waste time in the wrong database.

Step 1: Turn a topic into a research question

A broad topic (“stunting”) returns thousands of unfocused hits. Break it into four parts:

Population/problem — who or what is studied (e.g., under-fives in rural areas).
Variable/intervention — the factor examined (e.g., clean-water access).
Context — place/time (e.g., Indonesia, last 5 years).
Outcome — the result sought (e.g., stunting prevalence).

Then build a keyword table so your search reaches both Indonesian and English terms:

Indonesian term	English equivalent	Synonyms/variants	Exclude
stunting	stunting, growth faltering	gagal tumbuh (failure to grow)	obesity
air bersih	clean water	sanitation, WASH	bottled water
balita	toddler, under-five	anak bawah lima tahun	adolescents

Step 2: Build a Boolean query

The basic operators work in almost every database:

AND — both terms must appear.
OR — either term (wrap in parentheses).
”…” — exact phrase.
- (minus) — exclude a term.

Examples across fields:

Health: "stunting" AND ("sanitasi" OR "clean water")
Social science: "digital literacy" AND remaja AND ("social media" OR Instagram)
Engineering: "compressive strength" AND concrete AND ("rice husk ash" OR "silica fume")

Run the English variant of the same query to catch international literature (and, for Indonesian topics, the Indonesian variant too).

Step 3: Search each database

Garuda (Garba Rujukan Digital)

Indonesia’s official portal indexing Indonesian journals, articles, and conference proceedings (garuda.kemdiktisaintek.go.id). Type keywords into the search box, or browse via Publisher, Journal/Conference, and Subject to narrow by publisher or field. Each article record usually has an abstract, metadata, and a link to the full text/PDF on the journal’s own site. Garuda is strong for Indonesian-language papers that don’t always surface in global searches.

SINTA (Science and Technology Index)

Run by Kemendiktisaintek to rank national journals from S1 (highest) to S6 (lowest). Open Sources > Journals and enter a journal name or ISSN to see its tier. As a rough guide to the accreditation scores: S1 ≈ 85-100, S2 ≈ 70-84, S3 ≈ 60-69, S4 ≈ 50-59, S5 ≈ 40-49, S6 ≈ 30-39. Tiers come from the ARJUNA accreditation process (the backend), and SINTA is the showcase, also flagging Scopus/Garuda indexing. Use SINTA to judge a journal, not to download articles.

Google Scholar

Very broad, across disciplines and languages — good for an initial sweep. Time-savers:

“exact phrase” with quotation marks; author:"name" to restrict to an author.
Year range via “Custom range” in the left panel (e.g., 2021-2026).
Cited by — papers that cite this one; trace newer developments.
Related articles — similar work.
All versions — often links a free copy (repository/preprint).

Caveat: Scholar indexes everything — preprints, theses, and predatory journals included. It is broad but does not filter for quality.

DOAJ (Directory of Open Access Journals)

A vetted directory of open-access journals. You can search at the Journals or Articles level. Inclusion requires full open access, peer review (at least two independent reviewers), and an open license. The DOAJ Seal marks journals with best-practice standards (e.g., CC BY/BY-SA/BY-NC licenses). DOAJ works both ways: it finds articles you can legally download and reuse, and it verifies whether an open-access journal is actually credible.

Step 4: Judge journal and article quality

A high rank does not guarantee every article is correct or relevant. Check:

Ranking/indexing — SINTA (S1-S6), Scopus, or Web of Science. Rankings judge the journal, not each article.
Peer review — does the journal do it, and state the method?
Method and sample relevance to your question; an S1 article with the wrong method is still useless to you.
Date, DOI, and status — is there a DOI, and has the article been retracted or corrected?
Editorial transparency — a real editorial board, article-processing charges (APCs) stated up front, and a clear license.

Predatory-journal red flags (see the Think. Check. Submit. campaign): a flood of flattering email invitations, guarantees of very fast publication (“24-hour review”), hidden fees that appear only after acceptance, fake or non-consenting editorial boards, and unverifiable indexing claims (DOAJ/Scopus). Cross-check against DOAJ, Scopus/WoS, and the journal’s official site.

Step 5: Get the full text legally

Click the PDF/HTML link on the result if the journal is open access.
Use All versions in Google Scholar to find copies in an institutional repository (e.g., a university repository, RAMA) or an official preprint.
Use your university library access (subscription databases) or interlibrary loan.
If stuck, email the author — many will share their manuscript.

Avoid pirate sites; besides being illegal, their metadata is often unreliable.

Step 6: Save citations correctly

Record the DOI as the article’s permanent identifier.
Export BibTeX/RIS (via the Cite button in Google Scholar, and on most journal sites) into a reference manager (Zotero/Mendeley).
Deduplicate the same item pulled from different sources.
Verify the metadata (author names, year, pages, volume) before it reaches your bibliography — automated exports often get a name or year wrong.

Worked example (illustration): from question to five articles

This is a hypothetical illustration of the workflow — the counts and article details below are examples, not references to real articles or DOIs. Run the steps on your own topic to get real articles.

Question: “Does clean-water access affect stunting prevalence in Indonesian under-fives, 2021-2026?”

Query "stunting" AND ("air bersih" OR "sanitation") in Garuda → 3 SINTA-ranked Indonesian-language articles with field data. Include: design and location fit.
English query in Google Scholar, 2021-2026 range, follow Cited by on a key paper → 1 national study. Include: Indonesia-wide coverage.
Check DOAJ for 1 open-access review article. Include: clear license, legal to cite and download.
Exclude: an article with no DOI from an unverified journal; 1 S1 article that is actually about obesity (not relevant).

Result: five articles with recorded include/exclude reasons — a clean base for your literature review.

If your goal is to publish

If the task is finding a venue to publish, reverse the workflow. Use SINTA and DOAJ to build a shortlist of journals that fit your field and level, then open each journal’s official site and check:

Aim and scope — is your topic actually in scope?
Ranking/indexing — SINTA (S1-S6) or Scopus, matched to your institution’s or supervisor’s requirements.
Article-processing charge (APC) and license, stated up front.
A valid ISSN/e-ISSN and a reasonable publication schedule.

Also check the review timeline and accepted manuscript language. Avoid journals promising instant publication or hiding fees — predatory red flags apply both ways, whether you are citing or publishing.

Go deeper with Ison Slate

Searching many sources at once, ranking relevance, and assembling citations is slow. Ison Slate is built for academic research. A ready-to-use prompt:

“Find articles from 2021-2026 on the effect of clean water on stunting in Indonesian under-fives, prioritise SINTA 1-2 and peer-reviewed journals, then export BibTeX.”

Slate searches across sources, filters by those criteria, and assembles the citations, so you can focus on reading and writing.

Questions that change what you do

What’s the difference between SINTA and Garuda?

Garuda is a search engine for Indonesian articles and journals (to find papers). SINTA is a ranking system that rates journal quality (S1-S6) and indexes publications. Use Garuda to search, SINTA to judge.

Is a SINTA 1 journal always the most relevant?

No. SINTA 1 signals high journal-management quality, but relevance depends on how well the topic, method, and sample match your question. A well-targeted S3 article beats an off-topic S1 one.

How do I limit to the last 5 years?

In Google Scholar, use “Custom range” (e.g., 2021-2026) in the left panel. In Garuda/DOAJ, filter by publication year. Favor recent work for fast-moving topics.

Where can I find legal free PDFs?

Prefer open-access journals (DOAJ), Scholar’s All versions, and university institutional repositories. Otherwise use library access or ask the author directly. Avoid pirate sites.

How do I spot a predatory journal?

Watch for flattering email invitations, promises of instant publication, hidden fees, fake editorial boards, and uncheckable indexing claims. Verify against DOAJ, Scopus/WoS, and the Think. Check. Submit. checklist.

Is Google Scholar enough on its own?

For an initial sweep, yes. But Scholar doesn’t filter quality and is weak for some Indonesian journals. Complement it with Garuda (Indonesian coverage), SINTA (judging journals), and DOAJ (verified open access).
