Land use change is one of the causes of the decreasing of hydrological function that affects the hydrological response of a watershed. Planning of watershed management needs to be conducted to improve the hydrological function of the watershed. This study aims to determine the hydrological response in supporting watershed management planning in Opak Hulu Watershed. This research was conducted using the Soil and Water Assessment Tool (SWAT) hydrological modeling. The method used included data collection, processing of input data, running of SWAT model, calibration, validation, and the decision of the best watershed management scenarios. The results of the analysis of land use changes in the Opak Hulu Watershed in 2012–2017 had a significant increase in mixed upland agriculture (3.21%) and shrubs (1.43%). Meanwhile, open field (2,31%) and dry land agriculture (1.71%) decreased significantly. Based on the analyzed hydrological scenario, Soil and Water Conservation techniques can decrease the surface runoff and increase the lateral flow and base flow. The scenario is able to decrease the surface runoff by 542.22 mm (27.09%). It increases lateral flow and base flow by 321.82 mm (13.15%) and 797.28 mm (18.32%), respectively. The best watershed management planning with Soil and Water Conservation technique is able to reach Annual Flow Coefficient value to 0,33 (moderate) and 69,85 (moderate) for Flow Regime Coefficient. Keywords: land use, soil and water conservation techniques, SWAT model, watershed

One of the priority watersheds to be managed in Indonesia is the Cisadane watershed due to the high degradation problems. The Cisadene watershed degradation could be indicated by a high river flow during rainy season, low baseflow in dry season, and high erosion and sedimentation. One of the main problems in the Cisadane watershed is a huge landcover changes in the Cisadane Hulu watershed that causes a decrease in water absorption region and a surface runoff. The study aimed to analyze landcover changes in the Cisadane Hulu Watershed during 2013-2018 and analyze the watershed conditions based on their hydrological characteristics. Analysis of landcover changes patterns was carried out by processing spatial data using GIS software. Analysis for hydrological characteristics was conducted by using SWAT modelling (Soil and Water Assessment Tool). The results showed that there were land cover changes during 2013-2018. The most significant landcover changes in the Cisadane Hulu watershed was residential area (455.95 ha). The result simulation scenario of the model SWAT showed scenario 2 was the best scenario for the management of the Cisadane Hulu watershed. The application of Soil and Water Conservation can decrease surface runoff by 32.1% and increase lateral flow by 8.89%. Therefore, it is expected that the results of this SWAT model simulation will be taken into consideration by the local government for the optimal management of the Cisadane Hulu watershed. Keywords: Cisadane watershed, land cover change, SWAT modelling

The main cause of flooding and erosion that creates critical land in various regions in Indonesia is surface runoff. The surface runoff will occur if rainfall exceeds the capacity of soil water absorption (infiltration capacity). The soil management of each land use could improve the infiltration capacity. The water movement both on the surface and in the soil determines the water infiltration. This study predicts surface runoff based on the infiltration rate of various land uses and rainfall in the Ciliwung Watershed. A series of studies were performed in the upstream and middle areas of the watershed. Observations of soil properties, water movement, and rainfall were carried out in various dry land uses. The results showed that the soil's physical properties mostly determine the constant infiltration rate, which affected the water movement in the soil. The initial water content, the degree of saturation of the initial moisture content, and the soil's physical properties determine the time of constant infiltration rate. The value of constant rate infiltration and the time of its achievement determine the amount of surface runoff that occurs. Keywords: hydraulic conductivity, run off, soil management, time achievement of infiltration capacity

Surface runoff is a primary driving factor for water regulation services on oil palm plantations as it determines the hydrological components and other biogeochemical process. Therefore, understanding on their interaction and contribution within the watershed system is important to support decision-making system. Here, we applied Soil and Water Assessment Tools (SWAT) model to simulate water regulation services for an intermittent micro-catchment dominated by oil palm plantation in Harapan Landscapes, Batanghari Regency, Jambi Province. In this study, we used two different runoff curve number (CN) approaches in the SWAT model, namely the soil moisture curve number (CN-SM) and the plant evaporation curve number (CN-ET), to evaluate their applicability and uncertainty for assessing water regulation services. SWAT was automatically calibrated and validated against daily observed streamflow data. The results showed that the model performed well as indicated by hydrograph visual interpretation and statistical indicators. The performance was good for calibration and validation for both approaches with high R2 and Nash-Sutcliffe Efficiency (NSE). Also, the uncertainty was acceptable with P-factor >70% and R-factor <1. Differences in CN-SM and CN-ET's conceptual structure have caused variations in the calibrated parameters' best-fit value and their sensitivity to streamflow simulations, which implicated for other components' output water regulation services. However, CN-ET approach was less responsive to area's biophysical conditions for runoff generation than CN-SM one. This implicated that CN-ET generated low soil water storage and an overestimated actual evapotranspiration. This modeling exercise showed selection of a runoff CN approach by considering biophysical characteristics is important for calculating and simulating water balance component in such watershed. The accuracy of the simulation will significantly influence watershed management recommendations to improve water regulation's sustainability.

One major river flowing through Bekasi City is Bekasi river. Total extent of the Bekasi watershed is about 39.045 ha, in 2002 with rainfall of 250 mm for 8 hours caused about 138 ha flooded in residents area for 2-3 days in Bekasi City, more extremely in 2005 with rainfall only 127 mm for 6 hours caused about 164 ha flooded in residents area for 3 days. This evidence showed that flood problem in Bekasi City is become worse, and seem to be more horrifying in the future. Therefore, the flood problem needs an extremely great attention. The objectives of the research is (1) analysis watershed condition; (2) analysis of the causes of flood over Bekasi City from the perpective of hydrology and hydraulic; (3) plan of Bekasi watershed management to reduce flood risk in Bekasi City. To obtain the purposes of this research, the method of analysis is devided into four main subjects: (1) analysis of watershed condition using SCS method; (2) hydrology analysis using hydrology modeling HEC-HMS; (3) river flow capacity using hydraulic modeling HEC-RAS and (4) plan of scenarios to reduce flood risk. There are four scenarios to overcome the flood problems: (1) similarly with government plan 2010;(2) managing Bekasi watershed area with conservation tillage; (3) build water retarded structure entire of watershed and;(4) combination of second and third scenarios. The research results shown that river flow capacity only 462 m3/s is not enough to flow the discharges, otherwise the land use is change and increasing the run off in upstream. Based on the problems, it is expected to overcome the flood problem by managing Bekasi watershed area with conservation tillage and build water retarded structure. It will reduce 28.58% of the discharge run off in 2020. Key words: flood, land use changing, watershed management

Salah satu penyebab banjir dan erosi adalah kondisi biofisik di bagian hulu Daerah Aliran Sungai (DAS) yang sudah tidak dapat mendukung fungsi hidrologis DAS. Perlu dilakukan upaya-upaya penerapan teknik konservasi tanah yang tepat untuk memperbaiki fungsi hidrologis DAS tersebut. Penelitian ini bertujuan untuk: (1) menganalisis respon hidrologi berdasarkan kondisi biofisik DAS pada tingkat analisis skala meso, dan (2) menganalisis respon hidrologi berdasarkan penerapan skenario teknik konservasi tanah. Wilayah kajian untuk penelitian adalah di sub DAS Lengkong yang terletak di bagian hulu DAS Cisadane seluas 1,788 ha. Penelitian ini dilakukan dengan menggunakan pemodelan hidrologi Soil and Water Assessment Tool (SWAT). Hasil analisis respon hidrologi terhadap penerapan skenario konservasi tanah menunjukkan Koefisien Regim Sungai sebesar 149.71 untuk skenario 1 (penanaman tanaman strip) dan 2 (penanaman pohon mengikuti kontur), sebesar 149.80 untuk skenario 3 (pembuatan teras), sebesar 150.25 untuk skenario 4 (gabungan skenario 1 dan 2), dan sebesar 149.31 untuk skenario 5 (gabungan skenario 1, 2 dan 3). Berdasarkan nisbah erosi potensial dengan erosi yang dapat ditoleransi, diperoleh indeks bahaya erosi untuk skenario 1 sebesar 2.63 (sedang), skenario 2 sebesar 2.57 (sedang), skenario 3 sebesar 0.60 (rendah), skenario 4 sebesar 2.45 (sedang), dan skenario 5 sebesar 0.44 (rendah). Penerapan teknik konservasi tanah yang mengkombinasikan penanaman pohon mengikuti kontur dan penanaman tanaman strip dengan pembuatan teras secara bersamaan, merupakan teknik konservasi tanah yang terbaik untuk memperbaiki respon hidrologi DAS, sehingga dapat direkomendasikan untuk diterapkan di sub DAS Lengkong pada khususnya, dan di DAS Cisadane bagian hulu pada umumnya.

Evapotranspirasi (ET) merupakan komponen neraca air terpenting setelah curah hujan. Saat ini, pengukuran evapotranspirasi dapat dilakukan dengan menggunakan input data yang berbasis penginderaan jauh. Penelitian ini mengembangkan rumus empirik perhitungan evapotranspirasi, yaitu Blaney-Criddle, dengan memanfaatkan nilai Land Surface Temperature (LST) yang diekstrak melalui citra Moderate Resolution Imaging Spectroradiometer (MODIS) sebagai masukan dalam komponen suhu dalam persamaan tersebut. Validasi dilakukan antara nilai LST MODIS (akuisisi siang dan malam) dan nilai T Stasiun Iklim Darmaga, pada berbagai ketinggian (5 cm, 100 cm, 120 cm) dan waktu (07.00, 07.10, 13.00, dan 13.50 WIB). Pada LST siang, temperatur yang diestimasi oleh MODIS, lebih mendekati pengukuran temperatur stasiun iklim pada ketinggian 5 cm (dibandingkan dengan pengukuran temperatur pada ketinggian lainnya) dengan nilai R2 sebesar 0.36. Sedangkan LST malam, memiliki hubungan yang cukup kuat dengan T stasiun pada ketinggian 120 cm. Namun demikian, nilai R2 tertinggi didapatkan pada hubungan antara LST malam dengan T stasiun pada ketinggian 100 cm, dengan nilai R2 sebesar 0.57. Secara umum, nilai evapotranspirasi potensial yang berada pada DAS Cimadur berada pada rentang 4.45-5.65 mm hari-1 (mendekati kondisi sebenarnya). Dengan berbasis penginderaan jauh, nilai evapotranspirasi dapat disajikan secara spasial maupun temporal. Namun demikian, terdapat kendala terkait ketersediaan data yang menyebabkan nilai evapotranspirasi hanya tersedia pada bulan-bulan kering. Penelitian ini menunjukkan bahwa jika hal ini diperbaiki dengan mengkombinasikan data LST terbaik dalam 1 bulan, ketersediaan data evapotranspirasi potensial secara spasial dan temporal dalam satu bulan dapat meningkat >50% dari kondisi awal 0%.

Kelapa sawit (Elais guineensis Jacq.) merupakan salah satu tanaman yang memerlukan air dalam jumlah yang banyak. Ketersediaan air merupakan salah satu faktor pembatas utama bagi produksi kelapa sawit. Pada musim kemarau kelapa sawit akan mengandalkan cadangan air bawah tanah untuk kebutuhan airnya. Hantaran hidrolik merupakan parameter sifat fisik tanah yang berperan dalam penambahan air bawah tanah. Tujuan dilakukannya penelitian ini adalah mengetahui karakteristik hantaran hidrolik jenuh pada berbagai jenis lokasi yang meliputi gawangan mati, piringan, dan jalan pikul pada perkebunan kelapa sawit PTPN VII Lampung. Karakteristik ini dapat dijadikan acuan pengelolaan lahan agar dapat meningkatkan cadangan air bawah tanah. Nilai hantaran hidrolik jenuh pada lokasi gawangan mati berkisar antara 2.9-30.4 cm jam-1 dengan kelas sedang sampai sangat cepat, pada lokasi piringan berkisar antara 2.5-13.4 cm jam-1 dengan kelas agak lambat sampai cepat, dan pada lokasi berupa jalan pikul nilai hantaran hidrolik jenuhnya berkisar antara 1.6-12.8 cm jam-1 yang berada pada kelas agak lambat sampai cepat. Tingginya hantaran hidrolik pada gawangan mati disebabkan terjaganya struktur tanah oleh tumpukan pelepah yang sudah mati. Hasil penelitian menunjukan bahwa aktifitas pemanenan yang intensif menurunkan nilai hantaran hidrolik jenuh tanah pada areal piringan dan jalan pikul tempat mengangkut hasil panen disebabkan peningkatan kepadatan tanah.

Penurunan muka air pada lahan gambut memicu oksidasi dan subsiden, khususnya pada musim kemarau. Agar dampak penurunan muka air dapat dikelola dengan baik, maka perlu dikaji besaran komponen neraca air (water balance) yang meliputi: a) Pre-storage, b) Evapotranspirasi, c) Ruang pori drainase, d) Konduktivitas hidrolik dan e) Drainase. Penelitian ini bertujuan mengkaji komponen neraca air tersebut pada lahan gambut yang ditanami kelapa sawit yang dapat digunakan untuk menetapkan pengelolaan drainase yang optimal. Metodologi yang digunakan dalam perhitungan kedua komponen neraca air adalah persamaan Hooghoudt Steady-State Approach yang diverifikasi dengan pengukuran data lapang terkait tinggi muka air dengan menggunakan piezometer. Penelitian lapang dilakukan pada perkebunan kelapa sawit di Kabupaten Seruyan, Kalimantan Tengah. Selama musim kemarau (Juli-September), evapotranspirasi mencapai 386 mm yang melebihi besaran curah hujan (311 mm). Jumlah air drainase pada periode ini adalah 90 mm atau 1 mm hari-1. Berdasarkan nilai-nilai tersebut terdapat defisit air sebesar 25 mm selama periode musim kemarau. Jika jarak saluran drainase ditingkatkan dari 30 m menjadi 50 mm, maka terjadi surplus neraca air sebesar 34 mm. Namun surplus tersebut hanya mampu menaikan muka air tanah sebesar 2.3 cm dari kondisi awal yang berada pada kedalaman 40-50 cm. Dalam rangka menghambat penurunan muka air pada musim kemarau maka pada masa transisi dari musim penghujan ke musim kemarau perlu dilakukan konservasi air melalui peningkatan pre-storage. Di samping itu kehilangan air drainase perlu ditekan seminim mungkin melalui pengaturan jarak saluran drainase dan penggunaan cascaded stop-log pada sistem saluran tersier.
