AbstractThe purpose of this study was determined the amount of suspended sediment concentration dan sediment rating curve. Sediment rating curve are use to show the relationship between the discharge of the river and sediment discharge, a value sediment discharge can be used to predict the magnitude of the sedimentation process. Assesment of the suspended sediment have been made to overcome theproblems associated with the movement of contaminants, changes in water quality, to predict the lifetime of a dam on the river, and also to determine the rate of erosion due to changes in land use. Replanting at oil palm plantations, especially during land clearing that part of the land to be bare land. This condition causes the surface flow of replanted areas become rapidly concentrated into a ditch and into the river carrying sediment. The research results were obtained that the value of sediment discharge at the study site including the criteria for very high (greater than 20 tons/ha/yr) and already exceeds the limit sediment load criteria issued by the Ministry of Forestry. AbstrakTujuan penelitian ini adalah untuk mengetahui besarnya konsentrasi sedimen melayang (suspended sediment) dan kurva lengkung sedimen (sediment rating curve). Kurva lengkung sedimen merupakan kurva yang menunjukkan hubungan antara debit sungai dengan nilai debit sedimen sehingga dapat digunakanuntuk memprediksi besarnya proses sedimentasi. Kajian terhadap sedimen melayang (suspended sediment) telah dilakukan untuk mengatasi masalah yang berhubungan dengan proses pergerakan kontaminan (bahan penyebab polusi), perubahan kualitas air, memprediksi masa pakai dari sebuah bendungan disungai, dan juga untuk mengetahui laju erosi akibat perubahan tataguna lahan. Kegiatan peremajaan (replanting) pada perkebunan kelapa sawit, terutama pada saat pembersihan lahan (land clearing) maka sebagian lahan menjadi terbuka. Kondisi ini yang menyebabkan aliran permukaan dari areal peremajaanmenjadi cepat terkonsentrasi ke parit dan menuju sungai dengan membawa sedimen. Dari hasil penelitian yang dilakukan diperoleh bahwa nilai debit sedimen pada lokasi penelitian termasuk kriteria sangat tinggi (lebih besar dari 20 ton/ha/thn) dan sudah melebihi batas kriteria muatan sedimen yang dikeluarkan oleh Kementerian Kehutanan.

The water demand increases in line with the growths of population, industry and business, but the water availability is ascertained to satisfy those needs continuously. Therefore, it is necessary to analyze water availability in a specified watershed integrated with various aspects in hydrology. The objective of this study were (1) to identify of landuse at Prumpung watershed,(2) to determine water availability in Prumpung watershed by analyzing the relationship of rainfall and river discharge using the Soil and Water Assessment Tool (SWAT) and (3) to influence government policies relation with urban planning of Tuban Regency. The watershed is located in Tuban Regency and based on urban planning of Tuban Regency 2012-2032 which is covering 22,319.14 ha. Input data were Digital Elevation Models, land use, and soil map. The procedures were including collection and process of climate data, trend analysis of water availability, discharge measurements, discharge analyze and calibration using SWAT. The results of existing landuse showed that the minimum water discharge was 0.338 m3/s to the maximum 5,945 m3/s with groundwater availability was maximum until 3,070 mm on July to September 2014. SWAT has generated 27 HRUs that described the spatial condition of the whole watershed. Calculated discharges with SWAT compared to the measured discharges having The NashSutcliffe Efficiency (NSE) of 0.77 and correlation coefficient of 0.79. Conservation scenario has been conducted at several landuses for water availability and based on conservation area. The results showed that the minimum water discharge was 0.334m3/s to the maximum 4.842 m3/s with groundwater availability was maximum until 3,140 mm. There were no significant change of groundwater based on urban planning and scenario at Prumpung watershed, Tuban Regency.Identification of Prumpung watershed produced relatively small water discharge compared than water demand based urban planning of Tuban Regency. A plan of water management for exploiting of high rain fall in rainy season will contribute in consideration of the appropriate water supply/demand balance in dry season.

Soil and Water Assessment Tools (SWAT) which is developed in America was used to analyze the effect of land management on discharge, sedimentation, and water quality in a river basin area. The hydrological conditions in the Americas are different from Indonesia, so a modified SWAT is done. This research aimed to implement a modified SWAT program to predict the results of a better discharge analysis based on hydrological analysis in the sub-Watershed area. About 13.90% of the area was paddy fields. The evaluation of the module had been done by looking at the coefficient of determination (R²) and Nash-Sutcliffe Efficiency (NSE) based on the comparison of simulated discharge results with an observation discharge. Research began with delineation DEM, HRU formation, simulation, calibration, and validation. The R² value for daily data on modified SWAT was 0,725. It was better than the original SWAT and SWAT with Pothole, which were 0,706 and 0,708 respectively. Likewise, the NSE value for daily data on modified SWAT was 0,721, on original SWAT and on SWAT with Pothole was 0,668 and 0,685 respectively. The analysis result showed that the modified SWAT provide good discharge prediction results, indicated by relatively high R2 and NSE values.Keywords: hydrological analysis,modified SWAT, paddy field, pothole, SWAT

Sprinkler irrigation network could be a good investment when designed, installed, maintained and managed well. But manually calculation consumes much time and gives rise to human error. Therefore, this study aims to evaluate the performance of sprinkler irrigation using secondary data and the data was analyzed by using simulation of EPANET 2.0 software. This study was conducted on irrigation network in the village of Tenilo, Gorontalo and the villages of Akar-akar, NTB. The simulation resulted the average pressure at both locations was excess of the recommended optimum pressure 40 m, but it was not excess the maximum recommended pressure 65 m. The variation pressure on each location were 2.82 m and 9.35 m. Debit issued by sprinkler was also nearing discharge plan 9.11 liters/second. The velocity of the flow both locations was not different much. It was less than maximum allowable speed 3 m/s, it meant that the network was safe from abrasion and water hammer on a pipe. Based on the results, simulation sprinkler irrigation network installed in the village of Tenilo and the villages of Akar-akar have met the criteria of hydraulic limitation design of sprinkler irrigation.

The dam is a construction of water structures built across the river. The function of the dam is to hold and store water, both rain water, river water and water from the lake which will then form a reservoir. Kadumalik Dam is one of the projects of the Directorate General of Water Resources (SDA) of the Ministry of Public Works and Public Housing (PUPR) which will be built in 2020 on an area of 500 Ha. The purpose of building Kadumalik Dam is to meet the irrigation needs of the Irrigation Area (D.I) and meet diverse water needs, but the dam can also pose a great risk as well, namely the risk of accumulation of sedimentation. Sedimentation is one of the factors that is very influential in dam management. A large sedimentation rate will speed up the service life of the reservoir so that the planned reservoir function can be disrupted. Therefore this research is important to know how much the dam capacity and how old the dam service. This study uses analytical calculation methods for sediment transport based on observations and calculation methods with efforts to handle sedimentation. Based on the results of the analysis, the sedimentation rate in the Kadumalik Reservoir is 2.71 tons / ha / year and is classified as an erosion hazard class I or very light erosion rate, calculation of the method with sedimentation handling measures results in the analysis of the Sediment Control Building (BPS) can control 2.2 million m3 of sediment, so that it can extend the reservoir service life to 50 years.
