This paper approaches the spectrum of theater studies in Indonesia in an interdisciplinary manner, encompassing both descriptive and normative perspectives. From a descriptive standpoint, the spectrum is shaped by various ways of attributing meaning to theater as an entity. In a normative approach, various disciplines offer perspectives that contribute to creating a spectrum of meaning for theater in relation to the life of Indonesian society. Through a literature review, the research identifies at least three approaches to constructing theater studies in Indonesia: synchronic, diachronic and, combined. These three approaches are drawn from disciplines outside of theater, such as historical, anthropological, and sociological studies. Based on this perspectives, theater studies in Indonesia has moved from viewing theater in its meaning as a form of sacred ritual in the past to theater as symbolic capital today. These interdisciplinary perspective has an influence on the meaning of theater in theater studies itself as a discipline. Theater in Indonesia as a subject of study, therefore, is not only understood as an art that originates from dramatic works, but is more broadly understood as all forms of art that are centered on human action displayed in live performances, including sacred rituals, cultural performances, and theatrical protests.
