Diujikan

Diujikan is an Indonesian verb meaning “to be tested” or “to undergo testing.” It is a passive form used to indicate that something has been subjected to examination, trials, or evaluation by someone else. The term is common in scientific, regulatory, educational, and everyday contexts when describing products, methods, or hypotheses that have undergone testing.

Formation and grammar: The base verb is uji, meaning “to test.” Adding the suffix -kan yields ujikan, meaning “to test (something).” The prefix di- marks the phrase as passive, producing diujikan, “to be tested” or “to be subjected to testing.” The agent performing the test can be stated with oleh or omitted if obvious from context. Examples: “Produk ini telah diujikan.” (This product has been tested.) “Sampel tersebut diujikan oleh laboratorium independen.” (The sample was tested by an independent laboratory.)

Usage and nuance: Diujikan often emphasizes the act of testing itself rather than the tester. It is widely used in technical writing, product documentation, research reports, and policy discussions to indicate that verification, safety, efficacy, or compliance trials have occurred. Related forms include teruji (proven, tested), uji (test), dan pengujian (testing). The term can appear in both formal and informal registers, depending on context.
