Ekspulsi

Ekspulsi is a term used in Indonesian- and Malay-language contexts to denote the act of expelling or ejecting something from a system, organization, or body. The word is a cognate of the English expulsion and often appears in technical or disciplinary writings. Because ekspulsi is not a universally standardized term, its precise meaning depends on the field of use.

In biology and medicine, ekspulsi can refer to the expulsion of materials from a body or an organ, such as the discharge of fluids or other contents through natural or pathological pathways. In environmental and physical sciences, it describes the release of gases, liquids, or particulates from a container, chamber, or geological vent, typically driven by pressure differences or chemical reactions. In sociopolitical contexts, ekspulsi denotes the formal removal of a person from a group, organization, or country.

Mechanisms of ekspulsi vary by context. In physical systems, ekspulsi often involves rapid venting or ejection following a buildup of pressure. In biological systems, it involves regulated transport or excretion processes. In sociopolitical usage, it corresponds to organizational rules, legal actions, or policy-based decisions.
