teruji

Teruji is an Indonesian adjective meaning having been tested or proven. It indicates that a person, object, claim, method, or measurement has undergone formal or informal testing and has met a specified standard. The term is formed from the verb uji (to test) with the prefix ter-, which in Indonesian often yields a stative meaning such as “in a tested state” or “reliably proven.” In everyday and technical language, teruji is used to convey credibility: products described as teruji have typically undergone quality or safety testing; statements described as teruji have been evidence-supported; and conclusions described as teruji reflect empirical validation.

Common collocations include teruji secara ilmiah (scientifically tested), teruji secara klinis (clinically tested), teruji mutunya (its quality has been tested), and teruji keamanannya (its safety has been tested). The phrase is frequently seen in marketing copy, academic writing, and regulatory or quality-assurance contexts. Negation forms include tidak teruji or belum teruji for not yet tested.

Related terms include terbukti (provable, proven by evidence) and uji (to test) as the root verb; terpercaya (reliable, trustworthy) denotes broader trustworthiness. Etymological dictionaries such as the Kamus Besar Bahasa Indonesia (KBBI) document teruji as a standard Indonesian vocabulary item.

Note: The exact meaning of teruji can depend on context and the standards to which something is subjected; it does not, by itself, guarantee safety or quality, but indicates that testing has occurred.
