In this study, we introduce the concepts of (i, j) -semi^*- -open sets within the context of ideal bitopological spaces. This concept is demonstrated to be weaker than the established the notion of (i, j) -semi- -open sets. Subsequently, we define strong (i, j) -semi^*- -open sets in ideal bitopological spaces, elucidating some of their essential characteristics. Furthermore, leveraging this newly introduced concept, we establish the notions of strong (i, j) -semi^*- -interior and strong (i, j) -semi^*- -closure.
