kerataan

Kerataan is a noun used in Indonesian and Malay to denote the act or result of making something flat or even. In technical contexts it commonly refers to leveling or smoothing a surface or terrain, describing both the process of flattening a material and the state of being even.

Etymologically, kerataan is formed from the root rata (flat, even) with the prefix ke- to create a nominal concept and the suffix -an to indicate a state or action. It is related to the verb meratakan (to flatten or make even) and to the noun perataan (the act of leveling).

In practice, kerataan appears more often in technical or formal texts such as civil engineering, construction, agriculture, and land assessment. In everyday language, speakers frequently use meratakan or perataan to express the action of leveling or smoothing. The term may appear in government specifications, project plans, or legal documents that describe standards for leveling surfaces.

Kerataan can refer to surface finishing in contexts such as concrete work, road construction, or landscape leveling. It can denote both the process and the outcome, depending on context: for example, kerataan permukaan (surface leveling) or kerataan tanah (leveling of soil).

See also terms include meratakan, perataan, rata, and rata-rata (the mean).
