berkadar

Berkadar is a term used in Malay and Indonesian to describe the presence of a particular proportion, concentration, or content in a material, product, or substance. The word combines the prefix ber- with kadar, meaning "to have or possess a rate or proportion." It is used across contexts to indicate that a material contains a specified amount of a substance, often expressed as a percentage or gram per ton.

In mining and geology, berkadar describes the grade of ore, for example "ore berkadar tinggi" meaning high-grade ore and "ore berkadar rendah" for low-grade ore. In the food and beverage, pharmaceutical, and chemical industries, it is used to specify the concentration of an active ingredient, alcohol, sugar, acid, or other constituents, such as "minuman berkadar alkohol 40%" or "sediaan berkadar gula 5%." In environmental monitoring or regulation, phrases like "berkadar logam berat" indicate measured contaminant concentrations.

Usage notes: Berkadar is common in formal or technical writing, journalism, and industry literature in Indonesia and Malaysia. It is often paired with numbers (percentages, g/ton, etc.). The term is not commonly used in everyday casual speech, where more specific measurements or adjectives are preferred. An English equivalent is "having a concentration of" or "with a content of."
