Abstrak. Peningkatan curah hujan ekstrem dengan durasi lebih lama dapat meningkatkan frekuensi dan besar bencana hidro-meteorologi yang terjadi pada suatu wilayah. Hujan ekstrem dengan durasi lebih lama dan merata pada suatu wilayah telah menyebabkan kejadian banjir bandang pada beberapa kota di Indonesia. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis kecenderungan dan perubahan hujan ekstrem (2-harian) dan menggambarkan sebaran spasial kecenderungan hujan ekstrem ke dalam peta tematik. Data hujan dari 64 stasiun di wilayah Unit Pelaksana Teknis Pengelolaan Sumberdaya Air (UPT-PSDA) di Kabupaten Pasuruan (periode rekaman data dari 1980 ? 2015), digunakan sebagai input utama. Data hujan 2-harian diolah dari data hujan harian. Analisis kecenderungan menggunakan Uji Mann-Kendall, Rank-Sum, dan Median Crossing test. Hasil uji Mann-Kendall menunjukkan kecenderungan signifikan hujan 2-harian terjadi pada 12 stasiun. Hasil uji Rank-Sum menunjukkan delapan stasiun hujan mengalami perubahan hujan 2-harian signifikan. Berdasarkan uji tersebut secara keseluruhan wilayah UPT PSDA Pasuruan tidak mengalami kecenderungan perubahan hujan ektrim pada periode 1980 sampai dengan 2015.Abstract. Increased extreme rainfall duration can increase the frequency and magnitude of hydro-meteorological related disaster events. The extreme rainfall events with more prolonged duration have caused flash flood events in several areas in Indonesia. The aims of the study were to analyze the trends and shifts of 2-days extreme rainfall and to describe the spatial distribution of rainfall trend into thematic map layers. Rainfall data from 64 stations in the area of Water Management Unit (UPT PSDA) at Pasuruan (recorded from 1980-2015), were used as the main input. The 2-days extreme rainfall data was processed from daily rainfall data. The trend analysis used Mann-Kendall, Rank-Sum, and Median Crossing Tests. The Mann-Kendall test resulted in a significant trend of 2-days extreme-rainfall occurred in 12 rainfall stations. The Rank-Sum test showed that eight rain gauge experienced a shift. Based on these tests, we conclude that the overall area of UPT PSDA Pasuruan has not experienced the changes in extreme rainfall events from 1980 to 2015.

Abstract

Sedimentation is the accumulation of sediment materials in a location due to both surface erosion and cliff erosion that occurred in the water catchment area, and which was carried by the flow of water to that location. The purpose of this study was to determine the sedimentation rate by using slope data and rainfall intensity in the river basin area. The sample used in this study was the land located in the Kemuning watershed, in which the Kemuning watershed is a sub-watershed of the Bedadung watershed located upstream. Soil samples were taken from 3 different points, upstream, middle and downstream, then the soil was taken to the laboratory to be tested for the soil’s physical properties and the rate of soil loss using a rainfall simulator tool. The research results of soil erodibility in the upstream, middle area and downstream were 0.74 (very high); 0.59 (high); and 0.7 (very high) respectively. Moreover, the calibration of slope in the field to the rainfall simulator was 15°. We found that rainfall intensity which give the highest sedimentation in the upstream, middle and downstream area were 142.15 mm/h; 132.05 mm/h; and 137.43 mm/h respectively, with rainfall durations of 13.88 minutes; 15.50 minutes; and 14.60 minutes. Finally, the sedimentation measurement results using a rainfall simulator in the upstream, middle and downstream were 39904.04 mg/L; middle 85401.85 mg/L; and downstream 75530.00 mg/L respectively. We conclude that rainfall duration gives more influence to the sedimentation.

Abstract

Inappropriate land use and lack of cover crops may increase erosion rates. The purpose of this study was to compare the erosion rates of land use in Rembangan sub-watershed in 2001 and 2014. The erosion rates were calculated using a USLE (Universal Soil Loss Equation) method. The input data used were rainfall from 2004 to 2014, soil erodibility values based on field measurements, DEM (Digital Elevation Model), and land use maps in 2001 and 2014. USLE modeling showed that erosion rates in the study area in 2001 and 2014 were 873.1 tons/ha/year and 881.9 tons/ha/year, respectively. The erosion rates were classified as a very high level, which covered 42.5% of the total area. So, land conservation action is vital in the Rembangan Sub-watershed.

Abstract

The purpose of this research is to learn the working process of CGM model and to compare the water content value of model simulation with field observation. This researchwas done in the form of experiment. The parameters of the observation were the soilphysical observations, they are: the analysis of soil (soil texture), the analysis of bulkdensity (BV), the measurement of soil water content (KA) every 10 days, and themeasurement of the thickness of the soil layer. The calculation of the model then comparedwith the result of field measurements. The results showed that the texture of the soil layer 1and layer 2: sandy clay loam and layer 3: sandy loam. The grafic comparison of simulatedsoil water content (KA) and the observation indicates that the simulation model of watercontent value (KA) increases the decline in value. Meanwhile the value of water contentobservation of layer 1 is always over the water content of layer 2 and 3. This is influencedby soil texture factor in each layer of the peanut plants land, because the texture of the soilalso determines a water system in the soil like infiltration rate, rainfall, and water bindingability of the soil. Further research is necessary to observe the growth of plants as a resultof the water content of the soil and to compare with the results of a model simulations.

Abstract

This research proposes to evaluate whether there has been a change in hydrological regimes of the watershed. The research was conducted at the the administrative area of UPT PSDA Surabaya. Furthermore, Surabaya-Perning and Lamong-Simoanggrok watersheds were used as a sample for this study. The analysis was conducted using the Indicator of Hydrologic Alteration (IHA). The main input is the daily discharge data series from the two watersheds. The discharge data range from 1996 to 2015. Then, the time series data is divided into two periods, the pre-impact period (1996-2005) and the post-impact period (2006-2015). A total of 33 IHA parameters classified into 5 categories were used to evaluate the change. The results of the assessment are then used for RVA (Range of Variable approach) calculations. RVA calculations were used to discover changes occurring from the pre-impact period to the post-impact period. The data series from the two watersheds also analyzed using Environmental Flow Components (EFC) and Flow Duration Curves (FDC). The result of the research shows the difference in parameter value that indicating the hydrological change between the pre-impact period and the post-impact period. RVA analysis results show an increased flow in the Surabaya-Perning watershed from January to September and December. RVA analysis results also show an increased flow in the Lamong-Simoanggrok watershed from January to July and December. The results of the EFC analysis can provide information about flows that have the potential to cause floods and droughts. The Surabaya-Perning watershed has the potential to encounter a small flood with a value 254,7 m3/s which last for 9 days with a chance of occurring 0,5 times every 2 years.

Abstract

Upstream cultivation activities by use intensive fertilization have an impact on water quality degradation. Accumulation within several decades will cause damage to the hydrological conditions the watershed. Residual substances and heavy metals due to intensive fertilization will affect the biotic and abiotic components of the watershed ecosystem. Water in Indonesia is divided into several classes, namely class I, II, III and IV. Every class has a quality standard according to its designation class. This study aimed at evaluating the status of water quality based on physical and chemical parameters in the upstream area (rainfall catchment). Water sampling was carried out at three points, namely water sources (in), locations of aquaculture activities (irrigation), and rivers (out). Chemical parameter results showed that DO was 7.16 mgO2/ L in the river (out), BOD was 7.84 mg/L  in irrigation, COD in the river was 25,50 mg/L, the irrigation point nitrate was 6.75 mg/L, and pH average was 6.80 almost at each sample point. As for the physical parameters consisting of colour, smell, and temperature. The physical parameters based on Government Regulation No. 82/2001 were still in accordance with the specified quality standards. Management through monitoring river water quality requires an integrated model as an effort to conserve water resources. Result Rapid Rural Appraisal in the upstream area of the Bedadung Jember watershed showed that the role of institutions at the farm level was less than optimal. Communication between farmers level, agricultural extension workers, and several stakeholders was not good. Meanwhile, the participation of the community and several stakeholders had an important role as users of natural resources in conservation.

Abstract

Sengon (Paraserianthes falcataria) menjadi komoditas andalan sebagai bahan baku industri, sehingga sengon memiliki nilai ekonomis yang tinggi. Efek domino yang timbul adalah meningkatnya luasan lahan sengon, dan menyebabkan perubahan tataguna lahan ladang/sawah menjadi perkebunan sengon. Perubahan lahan tersebut rawan erosi yang akan memperbesar tingkat bahaya erosi. Peruntukan lahan yang tidak sesuai untuk komoditas tanaman sengon akan menjadi ancaman tersendiri bagi keberlanjutan agroindustry berbahan baku sengon oleh karena itu diperlukan evaluasi kesesuaian lahan tanaman sengon. Penelitian ini bertujuan mengidentfiikasi kesesuaian lahan tanaman sengon di DAS Bedadung. Infomasi ini digunakan untuk mengembangkan agroindustri yang berkelanjutan. Parameter yang dianalisis sebanyak 14 dan metode kesesuaian lahan adalah matching dan overlay. Hasil dari analisis kesesuaian lahan pada tanaman sengon didominasi kelas S3 “sesuai marjinal” (48,07%). Parameter pada lahan yang menjadi faktor pembatas tanaman sengon adalah curah hujan sebagai penyedia sumber air dan solum tanah. Upaya perbaikan faktor curah hujan yaitu membuat waduk atau bendungan, namun perbaikan tersebut membutuhkan dana banyak dan waktu yang lama. Sedangkan usaha perbaikan solum tanah sulit dilakukan karena membutuhkan waktu yang lama. Dengan demikian maka komoditas sengon di Kabupaten Jember akan mengalami kendala keberlanjutan apabila faktor-faktor diatas tidak dicari solusinya.
