Universitas Negeri Semarang (UNNES) plants and maintains campus landscapes using vegetation suited to local conditions, including drought-tolerant plants, to minimise irrigation needs. This approach integrates plant selection, the maintenance of established tree cover, and efficient watering practices into the management of campus green spaces. Reports published by university faculties in 2025 document how these practices support water conservation.
Selecting Plants with Lower Water Requirements
At the Faculty of Law (FH), landscape management includes planting and maintaining drought-tolerant vegetation across faculty grounds. A report dated 20 August 2025 describes the selection of plants adapted to tropical conditions with relatively low water requirements.
These plants help maintain green spaces during dry weather while reducing the need for intensive watering. Faculty maintenance combines suitable plant selection with regular care and efficient irrigation, linking landscape design directly to responsible water use.
Maintaining Established Trees to Reduce Irrigation Needs
The Faculty of Mathematics and Natural Sciences (FMIPA) also manages its landscape to minimise water demand. Its report of 6 November 2025 identifies established tree cover as an important component of green space management, supporting rainwater infiltration and reducing the need for intensive irrigation.
The faculty’s vegetation inventory records 76 mahogany trees (Swietenia mahagoni), 45 mango trees (Mangifera indica), and 39 glodokan tiang trees (Polyalthia longifolia). The report identifies these species as having good tolerance to dry-season conditions, supporting the maintenance of campus greenery with lower irrigation requirements. These figures describe the faculty’s vegetation inventory, rather than trees newly planted in 2025.
Supporting Water Conservation through Landscape Management
Beyond reducing watering needs, campus vegetation contributes to wider environmental functions. At FH, green spaces are managed to provide shade, moderate temperatures around buildings, absorb rainwater, and reduce surface runoff. These functions complement the faculty’s use of drought-tolerant planting and help maintain
