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.

Ciujung Watershed is the biggest and considered one of the major watersheds in Banten Province related to floods that take place almost every year in the area. The study aimed to review the SWAT (Soil and Water Assessment Tool) Model performance in predicting flow discharge and sediment yield to determine the best management practice to reduce those parameters in Ciujung Watershed. There were some steps in running SWAT model, including: (1) delineate watershed; (2) create Hydrology Response Unit (HRU); (3) HRU definition; (4) climate data input; (5) write SWAT input files; (6) run SWAT model; (7) calibration and validation; and (8) hydrological parameters simulation. The study showed that the model had a good performance in predicting flow discharge with R2 and NSE values in the calibration process of 0.83 and 0.65 respectively. Meanwhile, the model resulted in not a satisfying performance in predicting sediment yield with R2 value of 0.55 and NSE value of -193.62. The validation process in predicting flow discharge produced R2 and NSE values of 0.78 and 0.63 respectively. Land management practices used in this study are reforestation, land degradation rehabilitation, soil and water conservation practice with vegetative and mechanical methods, and all land management practice implementation. The last scenario is the best management practice that can be implemented in Ciujung watershed to maintain watershed conditions. The scenario produced the best river regime coefficient by 65 (moderate), reduced direct runoff and sediment yield by 46% and 95% respectively, and increased lateral and return flow by 32% and 80% respectively. Keywords: Best management practice, flow discharge, hydrological parameters, sediment yield, SWAT model

Pesanggrahan river with total extent of watershed about 13,384 ha is one of rivers flowing through Jakarta City that causes flood problem every years. Many effort has been done to reduce flood problem, among others is to build reservoir in watershed, but the effectiveness of reservoir is still questionable. A research aimed to analyze gap of reservoir capacity changes and its influence on hydrological response and to arrange the scenario of reservoir capacity change to improve hydrological response in Pesanggrahan Watershed was done using HEC-HMS Model. Reservoir capacity change scenarios applied to the actual rainfall condition and designed rainfall condition with a certain recurrence interval. The scenarios consist of: reservoir with the exsisting condition (scenario 1), increase depth of reservoir to 5 meters (scenario 2) and build 6 reservoirs on Pesanggrahan watershed (scenario 3). The model was calibrated using daily discharge data from the date of January 10th to April 30th 2009. Model calibration result shows that model is quite accurate to predict peak discharge in Pesanggrahan Watershed with Nash-Sutcliffe efficiency value = 0.9817 and R2 =0.975. Simulation results showed that the reservoir is effective in decreasing its local effect to peak discharge (reservoir area). The presence of reservoir with existing condition reduce only 6.38 % of the peak run off in outlet Kebon jeruk, whereas building of 6 reservoir will reduce 24.6 % of the peak run off in outlet Kebon jeruk.Keywords : HEC-HMS Model, peak discharge, Reservoir capacity change

Watershed management consists of multi stakeholders. Therefore, institutional aspect for regulating interaction among stakeholders is very important to be taken into consideration in watershed management. Watershed management will only be efficient if institutional aspect functioning in harmony. Objective of this research is to study role and coordination of cross sectoral government institutions in management of water resource conservation. In this research five elements of water resource conservation were analized, there are: 1) involved organizations, 2) related regulations, 3) management function performance (planning, execution, and controlling), 4) coordination aspect, and 5) priority instrument. Each of those elements was sub-divided into sub-elements according to analysis model used in this research. Two models were used in this analysis. Those are Interpretative Structural Modeling (ISM) and Analytical Hierarchy Process (AHP). Base on the analysis it is concluded that Big Agency of Lore Lindu National Park (BBTNLL), Agency of Watershed Management (BPDAS) Palu-Poso, and Forestry and Plantation Service of Donggala Regency were the most influential organizations in planning, execution, and controlling water resources conservation. Role of those organizations in the management activities were mainly regulated in the respective regulations. Coordination among acting organization is still weak due so the sectoral-ego and lack of qualified human resources.

The use and management of land resource which are unsuitable with its land capability will cause physical, chemical and biological-damage to the land and will disturb its hydro-orological function. The damage of land resources in a watershed needs improvement to increase its land quality. Optimal land use management planning based on its land suitability and hydrological aspects become important and need to be applied. The objectives of the study were: 1) To analyze land use change at Cijalupang Watershed, 2) To evaluate SWAT capability to predict impact of land use change on the hydrologic characteritics of the watershed, and 3) To provide land use plan based on land quality and hydrologic characteritics of the watershed. The result showed that optimizing land use management by integrating GIS and SWAT model at the Cijalupang Watershed was capable to increase land quality of the watershed. This was shown by the improvement of its land use capability to create better hydrological condition by decreasing run off 2.1 % and increasing base flow and lateral flow 0.4% and 0.4% respectively.

Forest destruction may affect forest hydrological functions either as a water regulator, maintaining the timing and distribution of river water flows, maintaining microclimate, or being able to protect the underlying areas from disasters such as floods. Revegetation is considered as an effort to improve the condition of forest and environment. The objective of this study was to examine the hydrological characteristics of soil under stands of Pinus (Pinus merkusii), Ugandan Mahogany (Khaya anthoteca), and Merawan (Hopea odorata Roxb). The method used is periodic measurement of soil physical variables. Our investigation reveals that hydrological and physical properties of soil under the stands were different. Within the same depth of soil, water content changed from the highest to the lowest in Pine (3.05%), Merawan Siput Jantan (2.40%), and African Mahogany (1.89%), respectively. The highest infiltration was 116.25 cm hour-1 under Pine stand, while the lowest was 24 cm hour-1 under Merawan Siput Jantan stand. The highest permeability was 13.27 cm hour-1 under Pine stand, while the lowest was 2.72 cm hour-1 under Merawan Siput Jantan stand. Dominated by clay, the soil texture was relatively similar in each stand. Further, the soil under the three stands were categorized as the soil hydrological group B.

Kondisi DAS Cisangkuy mengalami degradasi yang ditunjukkan dengan semakin seringnya kejadian banjir di musim hujan dan kekeringan di musim kemarau. Beberapa kecamatan di Kabupaten Bandung mengalami banjir tahunan. Pada 2013, banjir setinggi dua meter menyebabkan Kabupaten Baleendah terisolasi. Perubahan penggunaan lahan di DAS Cisangkuy merupakan salah satu penyebab menurunnya kondisi hidrologis. Peningkatan populasi di DAS Cisangkuy menyebabkan peningkatan permintaan air. Perubahan penggunaan lahan dan peningkatan populasi dapat mengancam ketersediaan air baku di DAS Cisangkuy. Tujuan dari penelitian ini adalah untuk menganalisis keseimbangan pasokan dan permintaan air DAS Cisangkuy dan untuk menganalisis dampak perubahan penggunaan lahan pada respon hidrologi DAS Cisangkuy. Hasil penelitian menunjukkan bahwa ketersediaan air DAS Cisangkuy dengan debit rata-rata 2015 memiliki jumlah air yang tersedia hingga 343,121,970 m3. Total ketersediaan air hingga 11,104,629,178 m3 pada tahun 2015. Berdasarkan hasil ini, ada defisit air hingga 10,498,001,277 m3 tahun-1.
