pemilah

Pemilah is an Indonesian term that designates a person or device that sorts or separates items according to predefined criteria. The word is formed from pilah, meaning to sort, with the agentive prefix pe- and suffix -lah, indicating an actor or instrument. In everyday language, a pemilah can be a person who sorts items, such as a pemilah sampah who separates recyclables from waste. In technical usage, pemilah refers to equipment designed to separate materials by properties such as size, density, color, or magnetism.

Industrial and technical use: In mining and mineral processing, pemilah encompasses devices like screens and sieves that separate ore by particle size, gravity separators that exploit density differences, magnetic separators for ferrous materials, and optical sorters that distinguish materials by color or reflectance. In agriculture and food processing, sorting machines remove broken or mis-sized products. In waste management and recycling, pemilah devices improve material recovery by isolating plastics, metals, and paper.

Operational considerations include throughput, separation accuracy, material properties, maintenance, and energy consumption. The term highlights a broad category of sorting and separation technologies used across manufacturing, mining, agriculture, and environmental services.
