Journal Description

The Indonesian Actuarial Journal (IAJ) is published by the Society of Actuaries of Indonesia (Persatuan Aktuaris Indonesia). It is a journal dedicated to the development of actuarial science. It covers both theoretical and applied mathematical methods.


The boundaries of actuarial mathematics are defined by the area of application rather than the uniformity of methods and techniques. Therefore, a paper of interest to the Indonesian Actuarial Journal (IAJ) may have its theoretical basis in actuarial science, probability theory, statistics, operations research, numerical analysis, data science, mathematical economics, or any other area of applied mathematics. The main criterion is that the paper should have specific relevance to actuarial applications.


The Indonesian Actuarial Journal (IAJ) is published two times a year, in July and December.
