Abstract

Abstrak Perubahan tata guna lahan akibat peningkatan jumlah penduduk mengakibatkan bertambahnya area pemukiman. Meningkatnya kebutuhan manusia terhadap tempat tinggal dan aktivitas lainnya menyebakan terjadinya beberapa permasalahan lingkungan semakin kompleks. Apabila keadaan ini berlangsung secara terus menerus maka menyebabkan menurunnya kemampuan tanah dalam menyerap dan menampung air hujan terutama di kawasan DAS Krueng Keureuto. Tujuan Penelitian ini adalah mengetahui seberapa besar perubahan tata guna lahan terhadap perubahan hydrograph aliran pada Sub DAS Krueng Keureuto. Data yang digunakan adalah data DEMNAS dan data citra satelit landsat 8 tahun 2015 dan 2021. Berdasarkan peta tata guna lahan tahun 2015 dan 2021, terjadi penambahan luas area ladang sebesar 4,75%, pemukiman 6,34%, perkebunan 11,83%, semak belukar 5,75%, dan sungai 0,21%. Adapun area yang mengalami penurunan luas yaitu hutan sebesar 27,67% dan sawah 1,21%. Hal ini berdampak pada laju limpasan permukaan dan besarnya debit aliran sungai yang terpantau pada outlet DAS Krueng Keureuto. Kata kunci: tata guna lahan, daerah aliran sungai, keureuto   Abstract Increasing human needs for housing and other activities have resulted in several complex environmental problems, such as a decrease in the soil capacity to absorb and hold rainwater, especially in the Krueng Keureuto watershed area. The aim of this research is to determine how much land use changes have affected changes in the flow hydrograph in the Krueng Keureuto Sub-watershed. The data used is DEMNAS data and Landsat 8 satellite image data for 2015 and 2021. Based on the 2015 and 2021 land use maps, there has been an increase in the area of fields (4.75%), residential (6.34%), plantations (11.83%), bushes (5.75%), and rivers (0.21%). Meanwhile, the area that experienced a decrease was forest (27.67%) and rice fields (1.21%). This has an impact on the rate of surface runoff and the magnitude of river flow discharge monitored at the outlet of the Krueng Keureuto watershed. Keywords: land use change, watershed, keureuto
