Abstract

Land cover change is a major problem with environmental sustainability. The impact of the increasing population is urgent for the need for land for human activities. The purpose of this study is to determine the magnitude of land cover changes that occur in Sinjai Regency for the period 2014 to 2022. The research uses quantitative research. That is research that starts from a specific plan or a detailed set of questions or hypotheses. This research is closely related to the process of enumerative induction (induction based on calculations). Based on the analysis using imagery data, the rate of land change in Sinjai district was obtained as follows: : land cover in the form of mixed land decreased by 287.61 Ha, secondary forest decreased by 135.98 Ha, primary forest by 20.04 Ha, water body by 140.46 Ha and other uses increased by 586.53 Ha. Keywords: rate of change, land cover, temporal

Abstract

Land cover change is a transition process, such as agricultural land does not immediately turn into built-up land but into grass/soil or shrubs land cover change the transition process of land cover change. This study aims to (1) Determine the rate of change in the temporal function of the hedge. (2) Determine the value of the protection coefficient based on the results of satellite imagery analysis. The method used in this study is spatial descriptive, with land units as units of analysis or mapping units. In spatial description, the results of the study will be described and displayed in the form of a map. In this study, it will be described spatially and temporally the land cover and its effect on the index of protected function of the research area (Sinjai Regency Watershed). The analysis used is spatial analysis whose processing uses a Geographic Information System, with outputs including Land Use Maps and Land Cover Maps. In the period 2014 - 2022, there was a dynamic change in land cover in the Sinjai Regency watershed. The largest land cover that has changed is miscellaneous use which changed 49.87%, then mixed land which changed 24.66% and water body 12.20%. The index of the protected function of the Sinjai Regency Watershed in 2014 was 0.57 and in 2022 it was 0.50. During the period 2014-2022 there was an increase in the hedging function index by 0.02. Keywords: Temporal, Protected coefficient, Spatial

Abstract

The contribution of the mining sector to forest destruction in Indonesia has reached 10% and is now increasing every year to reach 2 million ha. Efforts to improve ex-mining land is by reclamation. The purpose of this study is to determine the design of reclamation activities and to evaluate the success of reclamation at PT. Citra Lampia Mandiri. The research method used is descriptive method with data collection techniques that are participant observation. Reclamation activities are carried out in several stages and activities that are systematic and well planned which have links between one activity and another in an effort to improve land quality. To determine the success rate of reclamation by providing an assessment of each reclamation activity, namely land use and revegetation, erosion and sedimentation control, top soil management, revegetation activities and plant maintenance. The results of the evaluation of the success rate of reclamation at PT. Citra Lampia Mandiri is 83% with good description.
