Pasir

Pasir is the Indonesian and Malay word for sand, a granular material composed of finely divided rock and mineral particles. In geoscience, sand is typically defined by particle size, ranging from about 0.063 to 2 millimeters in diameter, finer than gravel and coarser than silt. It is formed by the weathering and erosion of rocks and is transported by water or wind, accumulating in beaches, deserts, river channels, and dune fields.

Most sand consists mainly of silica in the form of quartz, but its mineralogy varies with source. Carbonate sands derived from limestone or coral, feldspathic sands from granitic rocks, and heavy-mineral sands enriched with minerals such as ilmenite, zircon, or magnetite occur in different regions. The color of sand is influenced by mineral content and impurities and can range from white or pale yellow to red, brown, or black.

Sand has many uses: construction aggregates for concrete and asphalt, glass manufacturing from high-purity silica sand, foundry molds, filtration media for water and air, and various industrial or landscaping applications. In maritime and desert environments, sands influence ecosystem dynamics and stability, including dune formation and coastal erosion.

Extraction of sand, especially from beaches or riverbanks, can have environmental and social impacts, including habitat loss, increased erosion, and water quality concerns. Sustainable management, land-use planning, and regulatory frameworks aim to balance economic demand with environmental protection.

Within Indonesian contexts, pasir is the common term for sand and is used in geology, construction, and daily language. The term appears across Indonesian and Malay usage, and is often encountered in discussions of beaches, deserts, and soil resources.
