Abstract

The purpose of this study is to analyze land use changes in the Kelara watershed and to assess the suitability of current land use changes with the spatial planning regulation of Jeneponto within Kelara basin. This study integrates various survey techniques, remote sensing, and geographic information system technology analysis. Geospatial information used in this study consists of Landsat ETM 7+ satellite imagery (2009) and Landsat 8 (2014) as well as a number of spatial data based on vector data which is compiled by the Jeneponto Government. Remote sensing data using two time series (2009 and 2014) are analyzed by means of supervised classification and visual classification.  The analysis indicated that land use type for the paddy fields and forests (including mangroves) converted become a current land use which is inconsistent with the spatial planning regulation of Jeneponto.The use of land for settlement tends to increase through conversion of wetlands (rice fields). These conditions provide an insight that this condition will occur in the future, so that providing the direction of land use change can be better prepared and anticipated earlier.

Abstract

The area of agricultural land, especially paddy fields, is related to the level of rice production. Conversion of agricultural land to non-agriculture will have an impact on the availability of rice supply. This study aims to identify changes in paddy field land use in 2005 - 2016 using high-resolution satellite imagery and calculate the need for rice per capita in Pallangga District. This research utilizes the application of geographic information systems in monitoring changes in paddy field use. The method used in the classification of land use is digitizing on screen. The conversion of paddy fields to non-paddy fields was obtained from the results of overlapping maps of Pallangga District land use maps in 2005 and 2016 and presented in the form of cross tabulations. The accuracy test results obtained the overall accuracy value of 98.04%, and the kappa accuracy value of 0.98. This study shows that paddy field area has decreased by 305.25 ha. The change consisted of 17.68 ha into a water body, turned into a garden of 132.86 ha and became a settlement of 154.71 ha. The conversion of paddy fields in Pallangga District in 2005-2016 affected rice production. The results of the analysis of the needs of rice per capita per year show that in 2017 Pallangga District is surplus in the supply of rice to its population. However, based on population projection, the decrease in land area and rice production in Pallangga Subdistrict in 2020 was unable to meet the rice needs of its population of 1,027 tons
