摘要

Sumberpitu water springs was the one of primary resources, not only for people living in around of Bromo Mountain, but also for people living in Malang City. The water spring was very important for them to sustain their life activities. The importance of that urged people to be aware how important conservation activities was. Understanding conservation activities was done using System Dynamics approach which was part of system thinking helping to be understand real life condition. Causal Loop Diagram (CLD) is a system dynamics form having feedback among the variables. Water-Human-Land System (WHLS) Sumberpitu water spring Conservation was used as CLD Model. The CLD Model used Groundwater Storage including Sumberpitu water spring, Built- Up/Opened Area and Agricultural Areas in the Upper stream of water springs, and Rural and Urban Population as primary variable. The variables have both influence and feedback to each other. Conservation activities were done by local people including water prices variable as environment services charge, conservation education variable, and Adat Karo traditional ceremony as a local wisdom. For sustaining Sumberpitu water spring use, the conservation activities were expected to control, not only water use, but also land use change in the upper stream of water springs.
