Abstract

Land use conversion is a phenomenon of land use changes. The changes of land use and climate will affect on agricultural productivity. The purpose of this study was to analyze the changes of land use and climate that occurred in Jumantono District and the correlation between the land use conversion and the climate changes to agricultural productivity. This research was conducted in Jumantono District and Laboratory of Pedoogy and Climatology in Agriculture Faculty. Data be analyzed quantitavie descriptively and by correlation. The results showed that there was a change of land use area according to BPS in 2006-2007 and according to Google Earth Image analysis in 2004-2011 or 2011-2014 there ware changes of land use. Statistical analysis showed that land use changes and climate changes was significally correlated with land productivity.

Abstract

Samin sub-watershed is located in the district of Karanganyar and Sukoharjo regency. Every year an increasing number of people in Samin sub-watershed can inflict problems such as the seizure of land use and the amount of available water resources. This study purpose to analyzed the influence of land conversion and rainfall to hydrology conditions Samin sub-watershed in 2005-2015. This research used descriptive exploration method. The study population was the whole unit of land use in the Samin sub-watershed. Data collection techniques used collection of  secondary data from  BPS  Karanganyar-Sukoharjo regency and  watering hall.  Data  were analyzed using correlation analysis of land use and rainfall on hydrology conditions Samin sub-watershed. The results showed that the wetland and forest land decreased by an average of 44,76 ha-1year and 102,5 ha-1year. Residential land, fields and plantations increased by an average of 26,8ha-1year, 54,07ha-1year and 26,82ha-1year. In period 2005-2010 and 2011-2015, Samin sub-watershed has declined average on annual charge (-3.117,42 m3/second), value of coefficient run-off (-0,11), sedimentation (-0,01 mm) and increase average on value of  coefficient of river regime (+91,02) and CVcharge  (+0,35). Results of statistical analysis of correlation showed that, decline in wetland, forest and increased fields affect the increase coefficient of river regime. Decreased forest land also increased of fields land and plantations affect the  increase of  Coefficients of  Variants (CVcharge). Decreased forest land  affects decreased run-off coefficient, sedimentation and annual discharge.
