Abstract

In its management, watersheds must saw as an ecosystem. The ecosystem is an ecological system consisting of components that interact and have a relationship to form a unified whole. The purpose of this study was to identify changes in land use for the period 2010 and 2020 in the Tanralili sub-watershed in determining optimal management based on the watershed sustainability model. The data for the sustainability model is will obtained through the Analytical Hierarchy Process (AHP). The results showed that from 2010 to 2020, there was a decline in ​​industrial forest plantations, dry land mixed bush farming, and Savana by 126.81 ha, 339.33 ha, and 103.67 ha, respectively. In this period, there was also an increase in ​​secondary dryland forest, rice fields, shrubs, water bodies, and open land by 58.45 ha, 285.67 ha, 109.64 ha, 92.88 ha, and 23.18 ha, respectively. The hazard level of Surface Flow is the most important criterion in supporting sustainable watershed management, with a value of 0.472 or 47.2%. The next important criterion is farmers' income with a value of 0.202 or 20.2%; the next is food crop productivity with a value of 0.196 or 19.6%, and the last is flood/drought with a value of 0.130 or 13.0%. Industrial plantation forest has the highest value among other land cover aspects, with  0.183 or 18.3%. The next priority is dryland agriculture mixed with shrubs 0.166 or 16.6%, secondary forest 0.155 or 15.5%, water bodies 0.129 or 12.9%, rice fields 0.124 or 12.4%, shrubs 0.103 or 10.3%, savanna 0.088 or 8.8% and open land 0.053 or 5.3%.
