Author Guidelines

The Indonesian Actuarial Journal (IAJ) publishes original research in actuarial science and its applications in insurance, pension, risk management, and related fields. Before preparing a submission, please read these guidelines in full. Manuscripts that do not follow them are returned to the author before review.

1. Types of manuscript

The journal accepts three types of manuscript. Each submission must state its type on the first page.

• Original research article. A report of original work with a clear method, results, and conclusions. At least sixty per cent of the articles in each issue are of this type.
• Review article. A comprehensive and critical review of a defined topic. A review article must contain a section presenting the authors’ own analysis and original contribution, not a summary of the literature alone.
• Case study or short communication. A focused report which must still contain an objective or hypothesis, a method, results with analysis, and a conclusion.

2. Language and length

Manuscripts are published in English. The manuscript must not exceed fifteen pages in the journal template, including tables, figures, and references. Authors whose first language is not English are encouraged to have the manuscript checked by a competent speaker before submission; a poor standard of English is a ground for return without review.

3. Format

Use the official IAJ article template, which is available on the journal website. The template sets A4 paper with margins of 2 cm on all sides, Times New Roman 11 point, line spacing of 1.15, a first-line indent of 1.5 cm, and 6 points of space before each paragraph. Submit the manuscript as a Microsoft Word file with the extension .docx. Do not submit a PDF as the main document.

Two files are required at submission: the main manuscript, which contains the full author information, and a blinded manuscript, from which the names of the authors, their affiliations, their contact details, and any self-identifying acknowledgement or funding reference have been removed.

4. Structure of the manuscript

An original research article follows the structure of introduction, methods, results and discussion, and conclusions. A review article may instead follow the structure of introduction, discussion divided into sections, and conclusions. Headings are numbered consistently as shown in the template.

4.1 Title

The title must be concise, not more than twenty words, and must convey the key finding of the article rather than only its subject. Avoid naming the research location in the title unless the study is specifically about the characteristics of that region.

4.2 Author names and affiliations

Author names are written without academic degrees and without job titles. In the article metadata each name must consist of at least two words, a given name and a family name; where an author normally uses a single name, that name is entered in both fields. Family names must never be abbreviated to a single letter, because the metadata is used when the article is cited.

Each affiliation must state the institution, the city, and the country, separated by commas, and the name of the institution must be written in full rather than abbreviated. Superscript numbers refer to the number of distinct institutions, not to the number of authors; where all authors share one affiliation no superscript is required. The corresponding author is marked with an asterisk and gives an email address. Authors are asked to provide an ORCID iD.

4.3 Abstract and keywords

The abstract is a single paragraph of not more than three hundred words containing a brief background on the importance of the research, the objective of the study, a brief description of the method, the main findings, and a brief conclusion. It must not contain references, tables, figures, equations, or undefined abbreviations. Provide up to five keywords, in alphabetical order, using standard terms that reflect the key concepts of the article.

4.4 Introduction

The introduction must contain three elements, and a manuscript that lacks any of them is returned before review:

1. a state of the art overview of the relevant previous research, citing the most important and most recent studies;
2. an explicit statement of the novelty of the work, or an analysis of the gap in the existing literature that the study addresses; and
3. a clear statement of the objective of the research.

4.5 Methods

Describe the research design, the data sources, the observation period, the sample, any data cleaning applied, and the analytical approach, in sufficient detail for another researcher to reproduce the work. Where the study uses secondary data, name the source and give a link or a citation.

4.6 Results and discussion

The discussion must contain four elements: an appropriate and sufficient method, a description of the key findings supported by clear data, an interpretation of those findings in relation to previous concepts or theories, and a critical comparison with the findings of other researchers in relevant and recent publications. A discussion that describes results without interpreting them and without comparing them with other work does not meet the standard of the journal.

4.7 Conclusions

State the conclusions briefly, without introducing new interpretation or new discussion. The conclusions must answer the objectives stated in the introduction and emphasise the new or important findings. Implications, limitations, and recommendations for further research may be added.

5. Declarations

Five declarations are placed after the conclusions and before the references. All five are mandatory, and a manuscript submitted with any of them left blank is returned to the author. State each explicitly, including where the answer is that there is nothing to declare.

Declaration	What it must state
Artificial Intelligence Statement	Whether artificial intelligence tools were used in preparing the article and, if so, which tools and for what purpose. Artificial intelligence cannot be listed as an author.
Author Contribution Statement	The contribution of each author, preferably using the CRediT taxonomy.
Funding Statement	The source and grant number of any funding, or a statement that no funding was received.
Conflict of Interest Statement	Whether any conflict of interest exists in relation to the publication of the article.
Data Availability Statement	The availability of and access to the data, code, methods, or supporting material, subject to ethics, personal data protection, confidentiality, and intellectual property.

6. Tables, figures, and equations

Tables carry a caption above the table and use horizontal rules only, without vertical rules, with contents in 10 point Times New Roman. Figures carry a caption below the figure and must be legible at print resolution; colour may be used without restriction. Number tables and figures consecutively, refer to each of them in the body text, and explain them there rather than leaving them to speak for themselves.

Equations are centred and numbered consecutively in the format (1), (2), and so on, with the number aligned to the right margin. Vectors are set in bold italics and variables in italics. Every symbol must be defined at its first appearance, and every equation must be referred to in the text.

7. References

The journal uses the IEEE style. Citations appear in the text as consecutive numbers in square brackets in the order in which they first appear, for example [1], [2]–[4]. The reference list is arranged in the order of citation, not alphabetically. Every citation in the text must appear in the list, and every entry in the list must be cited in the text. Cite only items you have read; do not cite a work through a secondary source.

Three quantitative requirements apply to every manuscript:

• at least twenty references in total;
• at least eighty per cent of them primary sources, meaning journal articles, conference proceedings, theses or dissertations, manuscripts, or research monographs, rather than compilations of primary literature; and
• at least eighty per cent published within the last ten years. Classic works may be cited where they are the source of a problem or of a theoretical concept, but not as the basis for comparing findings or for justifying novelty.

Authors are required to use a reference manager such as Mendeley, Zotero, or EndNote, so that the style remains consistent throughout the article. Include a Digital Object Identifier for every reference that has one.

Examples of each reference type are given in the article template. Follow them exactly.

8. Similarity and originality

The manuscript must be original, must not have been published elsewhere, and must not be under consideration by another journal. The editorial office checks every submission with similarity detection software at screening and again on the revised version. A similarity score above twenty per cent, excluding references and properly cited quotations, is returned to the author for paraphrasing. A high score is not by itself evidence of plagiarism; what matters is whether a substantial block of text is traceable to a single source without attribution.

9. Copyright and licensing

Authors retain the copyright of their articles. By submitting, authors grant Persatuan Aktuaris Indonesia the right of first publication and a non-exclusive right to publish, reproduce, distribute, and archive the article, and to register a Digital Object Identifier for it. All articles are published under a Creative Commons Attribution-ShareAlike 4.0 International License. Authors are free to deposit the published version in a repository or on a personal website, with a citation and a link to the original publication.

10. Fees

The journal charges no submission fee and no article processing charge, and readers pay nothing to access the published articles.

11. Review process

Every manuscript that passes editorial screening is reviewed by at least three reviewers under a single-blind process. The expected duration of each stage is published on the Peer Review Process page. The journal does not offer a fast track and does not issue a letter of acceptance before a manuscript has formally reached the status of accepted.
