The Simulation of Land Use for Reducing Water Use Index in Sub-watershed Cacaban Karanggayam District Kebumen year 2013 (The Implementation for Teaching Material Supplement for the Basic Competence Analyzing the Relationship between Human and Environment as a Result of Hydrosphere Dynamics Class X Semester 2). Thesis, Teacher Training and Education Faculty Sebelas Maret University Surakarta. August 2014. The purposes of this study were to (1) determine the influence of the land use dynamics on water use index in Sub-watershed Cacaban year 2001 and 2013, (2) determine the land use simulation for reducing water use index in accordance with the function of sub-watershed Cacaban area, (3) determine the implementation of land use simulation results to reduce water use index in sub-watershed Cacaban Karanggayam District Kebumen year 2013 as a teaching materials supplement on the basic competence analyzing the relationship between human and environment as a result of the hydrosphere dynamics class X semester 2.This research was a descriptive study using combined approaches (quantitative-qualitative), and was designed using survey method. The population in this study was a unit of land in Sub-watershed Cacaban. The sampling technique was proportioned sampling and purposive sampling. The techniques of data collection were observation, documentation, interview, and laboratory testing. The techniques of data analysis to determine Water Use Index was done by comparing the availability of water based on Water Balance Thornwaite-Mather method and water needs based on Murtiono model, then the researcher did the simulation of the changing of land use based on the land function for reducing Water Use Index.The results showed that (1) Sub-watershed Cacaban, a change in land use was quite high during the 12 years from 2001 to 2013, especially in the use of dry land and garden, Water Use Index in Sub-watershed Cacaban for 2001 was 0.87 whereas in 2013 was 1.02. Based on the Regulation of Director General of Land Rehabilitation and Social Forestry about Monitoring and Evaluation Guidelines for Watershed No. 4 year 2009 Water Use Index Sub-watershed Cacaban in 2001 were classified into moderate with the range of values of 0.5-1, and the Water Use Index in 2013 were classified into bad since the value more than 1. (2) The application of simulated instruction of land use can reduce water needs, the reduction of water needs during one year were -1,039,661.9 m3/year. Therefore, by applying water needs after simulation can reduce the Water Use Index into 0.34 (from 1.02 to 0.68), and classified into moderate category. (3) the implementation of the results of the simulation of land use for reducing water use index in Sub-watershed Cacaban Karanggayam District Kebumen year 2013 as teaching material supplement Geography subject for the basic competence analyzing the relationship between human and environment as a result of hydrosphere dynamics class X semester 2.
