Abstrak. Perkebunan kelapa sawit di Kabupaten Nagan Raya mengalami perkembangan pesat dalam hal perluasan lahan dalam lima tahun terakhir sejak tahun 2009 hingga tahun 2013. Pada tahun 2009, luas total perkebunan sawit 27.434 hektar menjadi 40.216 hektar di tahun 2013. Perubahan tata guna lahan ini perlu diperhatikan karena dapat berpengaruh terutama pada ketersediaan air pada suatu DAS. Salah satu proses yang mempengaruhi hasil air pada suatu DAS adalah proses intersepsi. Penelitian ini dilakukan untuk mengetahui pengaruh intersepsi lahan kelapa sawit terhadap ketersediaan air pada sub DAS Krueng Isep dimana sub DAS ini merupakan catchment area untuk perencanaan PDAM serta sumber air untuk DI Jeuram. Metode penelitian ini dengan pengukuran secara langsung di lapangan untuk mendapatkan nilai curah hujan, air lolos, dan aliran batang. Lokasi penelitian berada di perusahaan perkebunan Kelapa Sawit di PT. Sucfindo yang terletak di Kecamatan Kuala Pesisir, Kabupaten Nagan Raya. Hasil penelitian yang diperoleh menunjukkan bahwa ketersediaan air pada sub DAS Krueng Isep dengan kondisi lahan kelapa sawit ditanami seluruhnya tidak mampu memenuhi kebutuhan air minum dan air irigasi (kebutuhan air total). Namun, pada saat sub DAS dengan kondisi lahan kelapa sawit dibatasi masih mampu memenuhi kebutuhan air total. Batasan maksimum yang diperbolehkan atau diizinkan penanaman kelapa sawit pada sub DAS Krueng Isep adalah seluas 95,94 km2.Abstract. Palm plantations in Nagan Raya experienced rapid development in terms of expansion in the last five years from 2009 to 2013. In 2009, the total area of palm plantations from 40. 216 hectares to 27. 434 hectares in 2013. Changes in land use should be noted because it can influence mainly on the availability of water in a watershed. One of the processes that affect the outcome of water in a watershed is the interception process. This study was conducted to determine the effect of palm oil interception against the water availibity in the Krueng Isep sub watershed which is a sub-watershed catchment area for planning taps and water sources for DI Jeuram. This research method with direct measurements in the field to get the rainfall, throughfall, and stemflow.The research location is in the palm plantation company PT. Sucfindo located in Kuala Pesisir Subdistrict, Nagan Raya District. The results obtained show that the water availability of the Krueng Isep sub watershed with the condition of land planted with palm wholly unable to supply the water drinking and irrigation demand (total water requirements). However, when sub-watershed with oil palm land conditions is limited still able to supply the total water requirements. The maximum limits allowed or permitted the planting of oil palm in Krueng Isep sub watershed is an area of 95,94 km2.

This study aims to predict the occurrence of erosion in the downstream Krueng Meureubo watershed, West Aceh Regency. Erosion is the loss of topsoil due to rain splash which is analyzed as a factor of rain erosivity, but the occurrence of erosion is not necessarily calculated by the occurrence of rain alone, but many other factors, such as soil erodibility, slope and length of land, land cover and the presence or absence of land conservation efforts. the. The Krueng Meurebo watershed shows a large sediment transport, with an indication that the river is getting shallower caused by sediment deposition at the riverbed, this sediment comes from sediment carried through the process of soil erosion. The method used in analyzing the occurrence of soil erosion in this study is the USLE method and uses a Geographic Information System (GIS). The results obtained are the distribution of erosion rate values in 228 polygons, with the largest erosion rate value occurring in polygon 1 with an erosion rate of 8495.308 tons/ha/year. The smallest erosion rate occurs in polygons 30, 34, 35, 179, and 180, with an erosion rate of 0 meaning that there is no land erosion event, which occurs in organosol and glehumus and regosol soil types, land cover is settlements and water bodies. It is concluded that the occurrence of erosion in a land is very dependent on the type of soil and the type of land cover. It is recommended for land with large erosion events to take serious land conservation actions so that erosion events can be minimized and do not occur continuously which of course can cause the watershed to become critical. Conservation efforts can be carried out in various ways, one of which is by vegetative means using plants that can reduce the rate of soil erosion.
