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.

Laju Deoksigenasi Dan Laju Reaerasi Sungai Bedadung Segmen Desa Gumelar Kabupaten Jember Sri Wahyuningsih; Elida Novita; Rizky Fathonah Imami

Bedadung River is the main river in the Bedadung Watershed in Jember Regency. People use the river to fulfill their daily needs and agricultural irrigation. Organic pollutants from domestic wastewater and agriculture wastewater that enter in river can decrease dissolved oxygen concentration, which can influence the river’s water quality. The river has a self-purification system with a reaeration and deoxygenation mechanism. The purpose of this study was to analyze the rate of deoxygenation and reaeration using the Streeter-Phelps method. Deoxygenation and reaeration rates influence oxygen concentration. This research took water samples using a Grab Sampling technique as the primary data at 5 nodes and 4 segmentations. The results of the research showed that the deoxygenation rate was 0.036 mg/L.day and the reaeration rate was 0.046 mg/L.day. This meant that the deoxygenation rate was lower than the reaeration rate so the self-purification can run quite well. The average DO value was 7.62 mg/L, showed that the river according to the class III water quality standard, so, the water quality was good and save to be used by the public. The research result can be used to determine the water quality carrying capacity in the next research.

Perubahan Tata Guna Lahan di Sub DAS Rembangan - Jember dan Dampaknya Terhadap Laju Erosi Idah Andriyani; Sri Wahyuningsih; Siska Suryaningtias

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.

Penilaian Daya Dukung Sungai Antirogo di Kabupaten Jember terhadap Beban Pencemaran Menggunakan Metode Streeter-Phelps Sri Wahyuningsih; Elida Novita; Deni Agung Idayana

The Antirogo River is a tributary of Bedadung Watershed which flows from Tegal Gede Village to Sumbersari Village, Jember Regency, East Java. The land areas near the River is used for agriculture, residential settlements, and industry. The wastes dumped from these lands degrades the water quality. Therefore, this study aimed to determine the river capacity against pollution loads, using the Streeter Phelps method in accordance with the Decree of Environment State Minister No. 110 of 2003. Water samples was taken from the River and divided into four monitoring points namely ATR01, ATR02, ATR03, and ATR04. A purposive sampling method was used and the water quality was analyzed. The average pollution load is 70.37 kg/day. Furthermore, the highest load is 81.04kg/day at ATR03 and the lowest is 64.81 kg/day at ATR04. Therefore, the river’s capacity can be determined by calculating the reaeration and deoxygenation rate, critical oxygen deficit, distance, and time taken to reach a point. The average deoxygenation rate is 1.77 mg/L.day, and that of reaeration is 16.13 mg/L.day. Also, the DOact values at ATR01, ATR02, ATR03, and ATR04 were 6.59 mg/L, 6.67 mg/L, 6.63 mg/L, and 6.67 mg/L respectively. The average value of oxygen deficit is 1.19 mg/L. According to the values of deoxygenation, reaeration, oxygen deficit, and DOact, it can be interpreted that the river is not in a critical condition, and, therefore, can tolerate pollutant load of 7.26 kg/day.
