Increasing population and development has resulted in inappropriate land use within watersheds that increase soil erosion. One of the hydrologic models that can be used to predict erosion and soil and water conservation in a watershed is SWAT. This research was conducted to predict erosion and the guidance of soil and water conservation in the Yeh Empas Watershed. This research was carried out in several stages, including data collection, data analysis and map validation using the ROC (receiver operating characteristic) and AUC (area under curve) methods. Results revealed that Yeh Empas Watershed had a very light EHL (erosion hazard level) category was found in the downstream area with an annual erosion value of 0 – 14.68 t/ha. In the middle area, the EHL was categorized as light with an erosion value of 15.44 – 57.22 t.ha-1.y-1. The upstream area has moderate EHL with a value of 65.20 – 178.64 t.ha-1.y-1. The validation of the EHL map using the ROC method showed a result of 0.83. This value was classified as very good. It can be concluded that SWAT predictions can be used in estimating erosion and soil and water conservation scenario to reduce 85% erosion. Keywords: Erosion prediction, Soil and water conservation scenario, SWAT models, Yeh Empas Watershed.

“…Daerah aliran sungai (DAS) merupakan wilayah tangkapan air yang berpengaruh besar terhadap ketersediaan air di suatu daerah. Pengelolaan daerah aliran sungai (DAS) perlu dilakukan sebaik mungkin untuk menjaga ketersediaan dan kualitas air [1]. Penduduk yang semakin bertambah mengeksploitasi sumber daya tanah dan air untuk memenuhi kebutuhannya.…”

Soil and Water Assessment Tool (SWAT) merupakan sebuah model hidrologi yang dikembangkan di Amerika Serikat untuk menganalisis dampak dari perubahan tata guna lahan terhadap hasil air (debit) dan sedimentasi. Model ini telah banyak diterapkan di Asia. Akan tetapi, neraca air di dalam model SWAT menggunakan neraca air untuk tanaman yang ditanam pada lahan kering (up land) termasuk tanaman padi. Di Asia, khususnya di Indonesia, tanaman padi umumnya ditanam di lahan sawah. Untuk menyesuaikan dengan kondisi lahan sawah, model SWAT telah dimodifikasi dengan mengacu kepada algoritma sawah yang dikembangkan oleh Sakaguchi et.al. (2014). Penelitian ini bertujuan untuk mengevaluasi kinerja model SWAT yang dimodifikasi untuk menduga debit Sub-DAS Cimanuk Hulu yang bersawah. Hasil evaluasi menunjukkan bahwa model SWAT yang dimodifikasi dapat menduga debit relative lebih baik dibandingkan dengan modul SWAT original (tanpa algoritma sawah) yang ditunjukkan oleh nilai determinasi (R2) dan Nash-Sutcliffe efficiency (NSE). Nilai R2 dari hasil kalibrasi model SWAT yang dimodifikasi, SWAT original lahan kering dan model SWAT pot-hole berturut-turut adalah 0.569, 0.494 dan 0.544. Sedangkan nilai NSE dari hasil kalibrasi model SWAT yang dimodifikasi, SWAT original lahan kering dan model SWAT pot-hole berturut-turut adalah 0.521, 0.420 dan 0.503

“…Running a SWAT model simulation is carried out if the data that has been entered is judged to be appropriate to minimize the occurrence of simulation failures to see the results of the model that has been created. The equation used in the SWAT simulation to predict runoff discharge is the SCS Curve Number method (Rau et al, 2015).…”

Water shortage problem was often happened in many places in Indonesia. Water availability is very important not only for domestic needs, but also for other activities particularly for agricultural activities. To solve water shortage problem, this study aimed to design a water source alternative. The rain is a free water source and collecting rain in the small dam or reservoir is one of the effective rainwater harvesting technique that can increase water availability. This research was conducted at Sekaran Village and the analysis had done using SWAT (Soil and Water Assessment Tools) model. The planned rainfall and discharge were analysed by 5 years return period to calculate the water potential for reservoir charging. The results of this study indicated that the location of the reservoir was planned in a forest area with a slope of 8-25%, on coordinates 111º38'11.39"E and 7º6'14.22"S and has a storage volume of 13737 m3. The reservoir has 4356 m2 surface area with a depth of 3 m. Based on the SWAT model simulation, the highest average discharge potential occured in February with a discharge of 0.312 m3/s and the lowest average discharge occured in October with a discharge of 0.044 m3/s. The total volume of potential annual water that can fill the reservoir is 61.166 m3/s per year based on a planned rainfall of 115.38 mm and a planned flood discharge of 2.54 m3/s with a return period of 5 years. The reservoir construction required a cost of IDR 1,200,747,000. Keywords: Cost, Location, Rainwater Harvesting, Reservoir, SWAT
