About Journal

Aims and Scope

The Indonesian Actuarial Journal (IAJ) covers actuarial science in both its theoretical and applied forms. A paper may draw on probability theory, statistics, operations research, numerical analysis, data science, mathematical economics, or any other branch of applied mathematics, so long as it bears directly on actuarial practice. The journal serves actuaries in practice and in research across Indonesia and the surrounding region.

Publication Frequency

The Indonesian Actuarial Journal (IAJ) is published by the Society of Actuaries of Indonesia (Persatuan Aktuaris Indonesia) and has been in publication since 2025. The journal is published twice a year in July and December.

Article Types

IAJ publishes original research, review articles, and empirical studies. Submissions must be original work, not under consideration elsewhere and not previously published.

Peer Review Process

Every article is peer reviewed: screened first by an editor, then sent to independent referees under anonymous review.

Research Misconduct and Post-Publication Discussion

The Indonesian Actuarial Journal treats research misconduct as a serious matter and handles every allegation in a transparent and documented manner, guided by the flowcharts published by the Committee on Publication Ethics.

Research misconduct includes, but is not limited to:

fabrication, that is the invention of research data or information;
falsification, that is the manipulation of research data or information;
plagiarism, that is the use of another person’s work, in whole or in part, without proper attribution, including the reuse of one’s own published work without citation;
invalid authorship, as defined in the journal’s authorship criteria;
undisclosed conflicts of interest that influence the content of an article; and
duplicate or simultaneous submission of the same manuscript to more than one journal.

Anyone may raise a concern about a published or submitted article by writing to the editorial office with a clear description of the concern and any supporting evidence. Anonymous allegations are considered only where the evidence supplied is sufficient to be examined on its own.

Every allegation is handled in five stages: initial report, clarification with the authors, investigation, decision, and corrective action. The authors are always given an opportunity to respond before any decision is taken. Where the authors are affiliated with an institution, the journal may refer the matter to that institution.

The corrective action may be a correction, a retraction, or the withdrawal of a manuscript that has not yet been published, as set out in the journal’s correction and retraction policy. Records of the process are retained by the editorial office.

Post-publication discussion is welcome. Readers who wish to comment on, question, or dispute a published article may write to the editorial office. Where the matter is of scientific interest, the Editor in Chief may invite the correspondent to submit a formal letter and invite the original authors to reply, and may publish both in a subsequent issue with their own Digital Object Identifiers. Correspondence is subject to the same editorial standards as other content.
