Ruangan

Ruangan is an Indonesian term for an enclosed interior space within a building, commonly translated as room or chamber. It is formed from the root word ruang with the suffix -an to indicate a defined interior area used for a particular function. In everyday language, ruangan usually refers to an interior space that is enclosed by walls and a ceiling, as opposed to ruang, which can denote space in a broader sense.

In homes and offices, ruangan are designated for specific activities, such as ruang keluarga (family room), ruang tamu (living room), ruang makan (dining room), and ruang tidur or kamar tidur. In institutional settings, ruangan include ruang kelas (classroom), ruang rapat (meeting room), ruang administrasi, and ruang arsip. The naming often reflects the intended use and helps organize movement and activities within a building.

A ruangan typically has at least one door and windows, plus a floor, walls, and ceiling. It is designed for comfort, safety, and function, with considerations for lighting, ventilation, acoustics, and accessibility. In tropical climates, ruangan may emphasize natural ventilation and shading, while in modern buildings mechanical systems support climate control.

The layout of ruangan is part of architectural planning and building regulations. Proper zoning, fire safety, and ease of maintenance influence how many ruangan a building contains and how they connect to corridors, stairs, and exits.
