ABSTRACT
Liliba water shed locate administratively at Kupang city and district of Kupang with about 4,534 ha of wide and about 20,176.22 m of main river length. Carrying capacity of Liliba watershed as natural resources (soil, water, and vegetation) is affected strongly by land cover conditions. Decreasing in water quantity is indicated by decrease in water discharge during dry season. Study had been conducted at Liliba Water Shed during September to November 2019. Change of land cover was analyzed based on classification land use at Liliba Water Shed during 2008-2018 Water quantity was observed by Mock method at 4 locations. Result of the study showed that land cover of settlement type increased from 20.39% in 2008 to 48.47 % in 2018. Shrubs type decreased from 19.73% in 2008 to 0% in 2018. Moreover, secondary forest areas decreased from 15.45% in 2008 to 10.14% in 2018. These conditions resulted in decreasing of water quantity. Maximum water discharge was 1.36 m3/second occurred in January and minimum water discharge occurred in October was 0.34 m3/second. Meanwhile, analyzed water quality indicated a light level of pollution in all parameters measurements.
