PJU

PJU most commonly refers to Penerangan Jalan Umum, the public street lighting system in Indonesia. This term denotes the installed network of streetlights, poles, electrical conduits, control cabinets, and related infrastructure that provides illumination for roads, sidewalks, and public spaces. Municipalities typically oversee PJU programs, guided by national standards for road safety, luminance levels, color rendering, and glare control. Projects often involve planning, procurement, installation of new luminaires (frequently LED), upgrades of pole infrastructure, and integration with smart-city control systems.

Operational aspects include routine maintenance, lamp replacement, fault response, energy management, and alignment with urban planning goals such as safety, accessibility, and reducing light pollution. Funding may come from local budgets, state or provincial programs, and public-private partnerships, with emphasis on energy efficiency and long-term lifecycle costs. The effectiveness of PJU depends on proper design, adequate maintenance, and regular performance monitoring to ensure adequate illumination and public safety.

In addition to its Indonesian meaning, PJU can be an acronym for other organizations or terms in different regions or fields. Context is important to determine the intended meaning. See also street lighting, urban infrastructure, and energy-efficient public works.
