Land cover index production has exceeded 80 % of the total area of the upstream catchment area of Mrica reservoirs, indicating the occurrence of land conversion. Elementary hydrological model, is predicted as an extrapolation tool that can help to understand the complexity of watershed management, including land conversion. Soil Water Assessment Tool (SWAT) is a physically based, deterministic, continuous, watershed-scale hydrologic models that was developed by the USDA Agricultural Research Service. SWAT was developed from numerous individual models within a period more than 30 years, and has been applied in several areas. The aim of this study was applying the SWAT on the upstream region of Mrica reservoirs. The method of the research was using the SWAT modeling procedure through a systems based on input output processes (IO). Output model was in the form of flow rate, validated by means of calibration and verification using statistical and graphical criteria on monthly scale. The results showed that their value of R2 = 0.61, NSE = 0.61, PBIAS = -0.61 % and MB = -0.25 for calibration, and R2 = 0.74, NSE = 0.73, PBIAS = -4.06 % and MB = -1.57for verification. The value of the statistical test showed that the model SWAT has good degree of precision and accuracy in watershed modeling. NSE values > 0.65 indicates that the SWAT model has an accuracy of very good degree. Several challenges in this watershed modelling are the availability and adequacy of data, the optimizationof parameters, time and computer resources. ABSTRAKIndeks Penutupan Lahan (IPL) produksi yang telah melebihi 80 % dari total luas kawasan Hulu Daerah Tangkapan Air (DTA) waduk Mrica, mengindikasikan telah terjadinya alih fungsi lahan. Model hidrologi elementer, dipandang sebagai alat ekstrapolasi yang dapat membantu untuk memahami kompleksitas pengelolaan kawasan Daerah Aliran Sungai (DAS), di antaranya alih fungsi lahan. Soil Water Assessment Tool (SWAT) adalah model hidrologi skala DAS berbasis fisik, deterministik, dan kontinyu yang dikembangkan oleh USDA (United States of Department of Agriculture) Agricultural Research Service. Model SWAT dikembangkan dari sejumlah model-model individu dalam periode lebih dari 30 tahun, dan telah diaplikasikan pada beragam wilayah, dalam rentang waktu yang cukup lebar. Penelitian ini bertujuan untuk mengaplikasikan model SWAT pada kawasan hulu DTA waduk Mrica. Metode yang digunakan yaitu menjalankan prosedur pemodelan SWAT melalui pendekatan sistem yaitu proses Input Output (IO). Luaran model berupa debit aliran, yang kemudian divalidasi dengan cara kalibrasi dan verifikasi menggunakan kriteria statistik dan grafis pada skala bulanan. Hasilnya menunjukkan bahwa nilai R2 = 0,61, NSE = 0,61, PBIAS = -0,61 % dan MB = -0,25 untuk kalibrasi, dan R2 = 0,74, NSE = 0,73, PBIAS = -4,6 % dan MB = -1,57 untuk verifikasi. Nilai uji statistik tersebut menunjukkan bahwa model SWAT mempunyai tingkat presisi dan akurasi yang baik dalam pemodelan DAS. Nilai NSE > 0,65 mengindikasikan bahwa model SWAT yang diaplikasikan mempunyai tingkat akurasi mencapai derajat sangat baik. Tantangan yang dihadapi dalam pemodelan DAS ini yaitu ketersediaan dan kecukupan data, optimasi parameter, waktu dan sumberdaya komputer.

Conceptual Approach On Development of Tidal Farming From Water Management Aspect, A Case Study at Kalimantan, Indonesia Sahid Susanto; Sigit Supadmo Arif
agriTECH Vol 7, No 1 (1987)
Publisher : Faculty of Agricultural Technology, Universitas Gadjah Mada, Yogyakarta, Indonesia

A lot of tidal irrigation land development projects were carried out in several locations of Kalimantan for new settlement and food production. A continuous research has been conducted to develop tidal agricultural land since 1971. Based on the research, a new concept for redesigning and reconstructing of tertiary demonstration block (TDB) should be develop. A conceptual approach on development of tidal farming from water management aspect has been proposed. The concept is presented in a model named Micro Water Management Model (MWMM): The basic concept of MWMM is improvement of micro water management and then be followed by improvement of all aspects.

Tropical Hydrology Simulation Model 1 For Watershed Management (Trophydsim-1) Sahid Susanto

A hydrological. simulation model, named the Tripical Hidrology Simulation Model I (Trophydsim-1), was created in order to simulate the run-off processes in mountainous terrain in a tropical monsoon region. The hydrological cycles in five major land covers, i.e., forest, upland, plantations (normally tobacco areas), paddy fields, and settlements, were each analogized by a series of four storages representing interception. depression, upper. zone and lower-zone storages. A set mathematical equations expressing empirical formula as well as physical law were employed in the model. An automatic parameter optimization routine was presented. The model was applied to the Kali Progo river basin. Central Java. Indonesia. which contains five subbasins. The simulated and recorded hydrographs were in close agreement both at every transfer point of the subbasins and in three different calendar years with different land use patterns.Some hydrologic characteristics were found from application of the model. The basin, which is mainly comprised of fresh volcanic formations. is capable of storing much water and releasing it gradually as groundwater flow. Therefore. the basin provides stable low flow for irrigating paddy land, which has expanded to 40 to 60 percent of the whole basin area. with multiple cropping patterns of rice-rice-upland crops or even rice-rice-rice.The model was also applied to simulate the effect on water regime of different modes of watershed management of simply land use patterns. Five scenarios representing extreme conditions of land use and four more realistic

The cereal production especially rice has increased sharply in Indonesia. The irrigation development program implemented by the government has become an important rote in the production process. However, expansion of irrigated paddy lands significantly influence the hydrological regime in its basin. A set of basic indicator for assessing the hydrological implication of the development in a river basin was proposed.

Sebaran komponen neraca air yang terdiri dari evapotranspirasi potensial dan aktuil, hujan, simpanan air dalam tanah, defisit dan surplus air di Indonesia dalam kondisi hujan normal diturunkan dari analisis neraca air dengan metode Thornthwaite yang telah dimodifikasi untuk wilayah beriklim muson tropik. Modifikasi ditekankan untuk mempertinggl akurasi perhitungan evapotranspirasi potensial dan konsep simpanan air dalam tanah. Neraca air dianalisis atas dasar data meteorologi yang dikumpulkan dari 99 stasiun terpilih. Lima wilayah hidrometeorologi dapat diklasifikasikan: 1) wilayah A dengan ciri tanpa defisit air tahunan, 2) wilayah B dengan ciri tanpa surplus air tahunan dan defisit ~ 200 mm, 3) wilayahC yaitu wilayah transisi yang mempunyai defisit maupun surplus air tahunan, 4) wilayah 0 yang ditandai dengan defisit air tahunan > 200 mm. Diperoleh keterkaitan antara klasifikasi wilayah dengan pengembangan irigasi untuk kepentingan pertanian. Semua komponen neraca air berikut wilayah hidrometeorologi disajikandalam bentuk peta.

Model hidrologi tangki Sugawara telah dimodifikasi dan diterapkan di lahan sawah beririgasi, dengan kajian kasus di petak tersier BP 1 Ka di DI Pijenan. Hasil kaliberasi model menunjukkan bahwa model dapat menampilkan unjuk kerja yang cukup memadai. Model selanjutnya digunakan untuk analisis regim air di petak irigasi tersier tersebut, dengan membagi regim air menjadi lima komponen, yaitu: (a) pemberian air irigasi, I; (b) evapotranspirasi aktual, Eta; (c) perkolasi, P; (d) air yang keluar dari petak, Qo; dan (e) kehilangan air tak terkontrol, L. Rata-rata jumlah air untuk masing-masing komponen diperoleh: I = 9,06 mm/hari (1,05 It/dt/ha); Eta = 3,69 mm/hari; P = 1,25 mm/hari; Qo = 1,63 mm/hari (0,19 It/dt/ha); dan L = 6,21 mm/hari (0,72 It/dI/ha). Nilai efisiensi pemberian air irigasi di petak tersebut selama penelitian berkisar antara 21% hingga 75%, dengan rata-rata sebesar 42%. Sedangkan untuk pemberian air irigasi yang optimal diperoleh angka 1,3 It/dt/ha.
