Rangka

Rangka is a term used in Indonesian to denote the skeleton or the structural frame of a body or object. It can refer to the physical skeleton of living beings as well as to the external frame that provides support and shape for man-made constructions. In addition to its literal meaning, rangka is often used metaphorically to describe the essential structure or framework of a system, project, or set of rules.

In biology and medicine, rangka tubuh refers to the skeleton, the internal framework of bones that supports the body, protects organs, and facilitates movement in conjunction with muscles. The concept also extends to other organisms, where their internal or external skeletons serve similar supportive and protective roles.

In engineering, architecture, and manufacturing, rangka denotes the structural frame of an object. For buildings and bridges, the rangka frame is the load-bearing skeleton usually made of steel or timber, designed to transfer forces to foundations. In vehicles, the kerangka kendaraan or chassis forms the base upon which components are mounted and from which stability and rigidity are derived. Different framing systems, such as kerangka baja (steel frame) or kerangka kayu (timber frame), determine strength, flexibility, and construction methods.

In figurative language, rangka appears in phrases like kerangka kerja or rangka kerja, meaning the framework or outline of a plan, policy, or procedure. These usages emphasize the idea of a foundational structure upon which details are built.

Etymologically, rangka shares roots in Malay and Indonesian, signifying skeleton or frame, and is used widely across contexts to denote the underlying support or architecture of physical objects and abstract concepts alike.
