Universitas Pertamina manages the campus landscape with attention to water efficiency through the maintenance of drought-tolerant vegetation and seasonal adjustments to irrigation. In November 2024, Universitas Pertamina conducted a campus plant inventory to document vegetation across our green spaces. This inventory provides a basis for identifying species with different water requirements and supporting water-conscious landscape management. Universitas Pertamina’s campus vegetation includes ketapang (Terminalia catappa), flamboyant (Delonix regia), and pink trumpet tree (Tabebuia heterophylla). University of Florida IFAS Extension classifies these species as having high drought tolerance, supporting their suitability for landscapes exposed to periods of reduced water availability.
Other species recorded in the inventory include peacock flower (Caesalpinia pulcherrima), bungur (Lagerstroemia speciosa), and jamblang (Syzygium cumini), which are recognised as drought-tolerant once established. The palm trees include palem putri (Adonidia merrillii), whose established specimens can tolerate short periods of drought. These characteristics support water-conscious planting, while recognising that newly planted specimens may require additional watering as their root systems develop.
The drought-tolerant species described above are distributed across Universitas Pertamina’s campus, forming part of the green spaces surrounding buildings, internal roads, and parking areas. Together with other trees, palms, planted borders, and lawns, they provide vegetation cover and enhance the outdoor spaces used by students, employees, and visitors.
Landscape watering at Universitas Pertamina distinguishes between lawns and other vegetation. Routine sprinkler irrigation is concentrated on ornamental lawns and grass-covered areas, which are generally watered two to three times per week. Other landscape plants rarely receive supplementary watering. Watering frequency changes with seasonal conditions. During the rainy season, supplementary watering is rarely carried out. During the dry season, sprinkler irrigation for lawns and grass-covered areas may increase to four to five times per week to meet their additional moisture needs. By maintaining established vegetation with relatively low supplementary watering needs and adjusting lawn irrigation to seasonal conditions, we support water-efficient landscape management while providing green and comfortable outdoor spaces for our students, employees, and visitors.
