“…SWAT (Soil Water Assesment Tool) adalah model hidrologi yang dikembangkan oleh Dr. Jeff Arnold pada awal tahun 1990-an untuk pengembangan Agricultural Research Service (ARS) dari USDA (Neitsch et al, 2011;Arnold et al, 2012) dan digunakan untuk prediksi dampak dari manajemen lahan pertanian terhadap air, sedimentasi dan jumlah bahan kimia, pada suatu area DAS yang kompleks dengan mempertimbangkan variasi jenis tanahnya, tata guna lahan, serta kondisi manajemen suatu DAS. Beberapa penelitian di berbagai negara dengan menggunakan model SWAT telah dilakukan di Amerika Latin (Stehr et al, 2008), di Eropa (Epelde et al, 2015), di Afrika (Zettam et al, 2017), di Asia (Bieger et al, 2015), (Nguyen & Nguyen, 2014) dan di Indonesia (Rahmad & Nurman, 2017).…”

The Use of SWAT Model to Predict Erosion and Sediment in the Catchment Area of Lake Tondano. The objective of this research is to assess the accuracy of SWAT model to predict erosion and sediment in the catchment area of lake Tondano. A comprehensive hydrological model of SWAT is one of several models available to predict erosion dan sediment load. The validation of this model would be tested and it would be acceptable if Nash-Sutcliffe model Efficiency (NSE) coefficient was equal or greater than 0.4. The results in this experiment showed that values of NSE coefficient between sediment load observed and predicted by SWAT were between 0.4 and 0.9. Therefore, the use of SWAT model to predict erosion dan sediment in Tondano lake catchment area is satisfying and very good. Keywords: Catchment area; erosion; sedimentation; SWAT; NSE Penggunaan Model SWAT untuk Prediksi Erosi dan Sedimen di Area Tangkapan Air Danau Tondano Abstrak Penggunaan Model SWAT untuk Prediksi Erosi dan Sedimen di Area Tangkapan Air Danau Tondano. Penelitian ini bertujuan menguji keakuratan model SWAT dalam menduga erosi dan sedimen di area tangkapan air danau Tondano. SWAT (Soil Water Assesment Tool) merupakan model hidrologi yang komprehensif karena mempertimbangkan kondisi biofisik, iklim dan manajemen area tangkapan air dalam prediksi erosi dan sedimen. Penggunaan model SWAT untuk pendugaan erosi dan sedimen di area tangkapan air danau Tondano dapat diterima apabila hasil validasi sedimen terukur dan sedimen pendugaan menunjukkan koefisien NSE (Nash-Sutcliffe model Efficiency) lebih besar atau sama dengan 0,4. Penelitian ini menunjukkan bahwa model SWAT bisa digunakan untuk prediksi erosi dan sedimentasi di area tangkapan air danau Tondano karena koefisien NSE yang diperoleh pada 4 sungai yang bermuara di danau Tondano berkisar antara 0,4 sampai 0,9. Dengan demikian, pendugaan erosi dan sedimen di area tangkapan air danau Tondano dengan model SWAT dapat memberikan hasil yang memuaskan sampai sangat baik.

“…Terjadinya bencana alam yang sering terjadi di beberapa daerah selama ini mengindikasikan telah terjadinya kerusakan lingkungan, terutama penurunan dari daya dukung daerah aliran sungai (DAS). Penurunan luas vegetasi merupakan masalah serius pada ekosistem DAS (Rahmad, Nurman, & Wirda, 2017). Kurangnya daya dukung DAS dapat dilihat dari semakin banyaknya lahan yang seharusnya dimanfaatkan sesuai dengan arahan penggunaan lahan tidak dimanfaatkan sebagaimana mestinya.…”

Tujuan penelitian ini adalah untuk mengetahui arahan penggunaan lahan di Daerah Aliran Sungai Percut dengan memanfaatkan Sistem Informasi Geografis. Populasi dalam penelitian ini adalah seluruh daerah Sub DAS Percut. Teknik pengambilan sampel yang digunakan adalah total sampling, yaitu populasi sekaligus dijadikan sampel. Teknik analisis data yang digunakan dalam penelitian ini adalah teknik analisis kualitatif dengan pengharkatan (scoring) pada parameter penelitian berupa overlay/ tumpang susun peta. Overlay peta merupakan teknik analisis dalam SIG untuk mengetahui dan melakukan analisis keruangan yang dilakukan dengan cara tumpang susun antara beberapa peta dengan berbeda, yang menggunakan perangkat lunak ArcGIS. Hasil penelitian menunjukkan bahwa arahan penggunaan lahan di DAS Percut terdiri dari 3 kawasan, yaitu Kawasan Lindung dengan luas 4.258,19 Ha atau 9,9% dari keseluruhan daerah penelitian. Kawasan penyangga yaitu dengan luas 9.250 Ha atau (21,7%) dan Kawasan Budidaya tanaman semusim dan permukiman yaitu dengan luas 29.250 Ha atau 68,4%.

“…A micro catchment area is an area bounded by topographic separators that receive rain, accommodate, store and drain into rivers and so on to lakes or seas (Asdak, 2010). A micro catchment area is a management unit of a natural resource that serves as a producer of goods or services that are beneficial to life (Rahmad et al, 2017). Such as agricultural areas, plantations, fisheries, settlements, hydropower construction, utilization of timber forest products, and others (Gunawan et al, 2014).…”

“…Several studies in various countries conducted by Zettam et al (2017) in Africa, Nguyen & Nguyen (2014) in Vietnam, Rahmad et al(2017), andChristanto et al (2018) in Indonesia showed that the SWAT method can simulate hydrological processes with Nash-Sutcliffe Efficiency (NSE) values > 0.5. The model is expected to be one of the considerations in planning the management of micro catchment areas with erosion and sedimentation indicators in the Air Lanang Area Micro Catchment.…”

This research aims to obtain erosion and sedimentation rate data in the micro catchment area of Air Lanang using soil and water assessment tool (SWAT) modelling within existing and scenario land uses. Geographically, the study area is located between latitude 3°26`23.48” - 3°31`46.09” S and longitude 102°24`11.74” - 102°28`26.35” E with a total area of 2987.06 ha. Soil analysis was conducted in the Soil Science Laboratory, Faculty of Agriculture, University of Bengkulu. The research data was analysed using SWAT model. Recorded data in this study were including soil analysis data, soil type map from land unit and soil map book Bengkulu sheet (0912) Sumatra, data of status area from KLHK, Digital Elevation Model National data from BIG, a set of climate data from BMKG, data of administrative border from RBI map Bengkulu Province and data of land use from the interpretation of satellite image and ground checking, as well as the scenario land use which was prepared following the community forest program from the government in the protected forest by converting the coffee plantation located within the protected forest area to woody plants with economic, social and conservative values. The results showed total erosion in the micro catchment area of Air Lanang with the existing land use in 2020 was 820731.87 ton year-1, while in the scenario land use was 288212.45 ton/year which were classified to very light, light, moderate, heavy and very heavy in class erosion. Based on the existing land use data, there was a decrease of erosion in the moderate to very heavy class of erosion for 7.27 % resulting in the very light and light class of erosion become 15.55 % after the simulation of the scenario land use model. The use of scenario land use model is effective to decrease erosion and sedimentation rate. The total sedimentation in the micro catchment area of Air Lanang in existing land use in 2020 was 354949.98 ton year-1 with the highest sedimentation in sub-basin 2 while the lowest sedimentation was found in sub-basin 12. On the other hand, the total sedimentation in the scenario land use model was 137365.04 ton year-1. The reduction of total sedimentation in existing land use in 2020 to the scenario land use model was 36.76 %.
