Notasi

Notasi is a term used in Indonesian to refer to a system of symbols, signs, and conventions that stand in for information, quantities, or processes. A notation provides a compact, precise way to represent complex ideas so that people can read, compare, and compute without ambiguity. In any domain, a notation consists of a set of symbols, rules for combining them, and agreed meanings for those expressions.

Musical notation encodes pitch and rhythm on staves with notes, rests, accidentals, time signatures, and tempo marks. Mathematical notation uses symbols and conventions to express numbers, operations, functions, and relationships, enabling compact formulas and formal proofs. In chemistry, chemical notation represents elements and compounds with symbols, formulas, reaction arrows, and stoichiometric coefficients. In linguistics, phonetic notation such as the International Phonetic Alphabet transcribes speech sounds. In computing and information technology, programming languages, data formats, and regular expressions provide formal notations for algorithms, data structures, and text processing.

Notasi evolves with practice and technology. Standardization by international bodies and the use of digital encodings such as Unicode support cross-system interoperability, making notation portable across languages and platforms. Good notation emphasizes clarity, consistency, and the ability to convey meaning with minimal risk of misinterpretation.
