Potentials use of leachate for turfgrass irrigation on soil coverage landfill Suwung Bali

Abstract

Abstract Climate change affect water quality and impact water resources and water supply thus using leachate for grass irrigation is hard choice. Suwung landfill is the largest landfill in Bali and was planted with turfrass and arranged as a park. This study aims to determine the potential use of leachate water for irrigation of turfgrass and determine the type of grass that is survive and suitable for landfills cover and irrigated with leachate water. The study was survey of field and observation by purposive sampling to observe the growth of grass and followed by analysis of the characteristics of leachate water and well water and soil. Results showed that using non potable water landfill leachate for irrigation of turfgrass during one year showed local seashore paspalum grew well, local Bermuda and Zoysia matrella showed relatively less growth inhibition than the Bermuda hybrid and Axonopus compressus. Grass growth on top hills is more survival than in slope and foot hill areas.
