In the past decade, the development of land retaining construction is growing rapidly as optimization of available land use. The purpose of this study is to hold the soil in order to avoid landslide due to the structural load other than the use of available space. The results of the sheet pile analysis at Pontianak Peaker PLTMG found that the SF number in the condition without earthquake (safe condition) is 2.00 and the number of SF in earthquake conditions is 1.40. Based on the results of sheet pile analysis at S-02 and S-03 points in conditions without earthquakes, low tide-without earthquakes, floods-without earthquakes, normal-earthquakes, receding earthquakes, and earthquake floods with earthquakes returning 500 years in analysis the structure and analysis of slope stability are said to be "safe" because the conditions without earthquakes SF values greater than 2.00 and earthquake conditions SF values greater than 1.40.

Discharge data is usually less available than rainfall data, so it is necessary to find a relationship between river flows that are applied in the period available rainfall data in a watershed area. The purpose of this study is to determine the suitability of the method based on the analysis of data validation between the observed discharge and the model discharge. The method is done by modeling the discharge based on rainfall with the Artificial Neural Network (ANN) MATLAB R2014b program. The Upper Brantas Watershed is used as a case study because it often has runoff problems. Validation of the ANN method was tested with Root Mean Square Error (RMSE), Nash-Sutcliffe Efficiency (NSE), Correlation Coefficient (R) and Relative Error (KR). From the results of calibration using the ANN Model, the best data is found in the five years data of epoch 500. Verification results based on the value of R have a relatively good relationship between observation discharges with model discharges. The validation results show the validity in a year data of epoch 500.

An accurate determination of water availability in the 10-day period of the Amprong River has an important role in the planting system to support the agricultural production process in DI. Kedungkandang, because if the availability of water is not precisely determined, there will be an error in regulating irrigation water and its use is not as expected. To overcome these problems, an analysis system is needed that is able to make predictions well. One of the time series models is the ARIMA (Autoregressive Intregated Moving Average) model. The model was built by 9 period discharge data, namely 2008/2009 until 2016/2017, to predict the discharge of period 2017/2018. Of the ten tentative models obtained, there are only five models that are worth using. The best model is the ARIMA model (2,0,1) (1,2,1) 36 with the value of MSE = 22,90; KR = 6.00; MSD = 8.05; MAD = 2.04; MAPE = 18.53 and MPE = -8.98. In second crop season the crop intensity of paddy increased from 55.79% to 64.50%, and the production of GBK increased by 13.50%. While the third crop season paddy crop intensity increased from 37.22% to 49.99%, and GBK production increased by 25.54%.

Groundwater is one of the many alternative water sources that have a large and very good quantity and quality. An important factor that must be considered in groundwater management is the analysis of its chemical characteristics. These chemical characteristics will have a large impact on objects that receive and consume ground water regularly. The purpose of this study was to determine the effect of the risk of the object receiving and knowing the chemical characteristics of groundwater in the study location. To find out the effect of the occurrence of risk on the research location, use the equation recommended by the EPA (Environmental Protection Agency). Analysis of the chemical characteristics of groundwater was carried out using the Pie Chart Method, and the Kurlov Method. From the results of research conducted in Gamping Village, Campurdarat District, Tulungagung Regency, it is known that the groundwater in the study site has health risk factors and is dominated by anion bicarbonate (HCO3 - ), and kation calcium, sodium.

When the rainy season arrives inundation occurs in some areas in Palu, the capital city of Central Sulawesi. It’s due to rapid development, outdated drainage systems, high level of sedimentation and the topographic condition. Solutions to overcome the problem are rehabilitating existing drainage, rainwater harvesting, gully plug and temporary storage pond equipped with automatic valve door. Rehabilitation is done by increasing the depth of existing drainage. For rainwater harvesting, the rain barrels capacity varies from 350 - 1050 liters equipped with storage well. By combining the rehabilitation and rainwater harvesting, the effectiveness of inundation reduction in DTA 1 93,5% and in DTA 2 99,6%. For gully plug, each size of gully plug is set to fit the width of channel. The effectiveness of inundation reduction 81% in DTA 1 and 98,9% in DTA 2. The budget plan for rainwater harvesting between Rp. 1.492.505,- to Rp. 2.692.505,- depending on rain barrel capacity. For gully plug between Rp. 556.000,- to Rp. 808.000,- depending on the size of gully plug.

Argosari Village is one of the villages that has cattle farms in Malang Regency. This research was conducted in one of the houses in Argosari Village and has 6 (six) of cows. In one day, each cow produces 100-150 liters of liquid waste. However, the liquid waste is immediately discharged into the drainage channel because there is no effort to process wastewater. On the results of laboratory tests, samples of wastewater, BOD, COD, TSS, NH3-N and pH in wastewater were respectively 4488 mg/L, 11000 mg/L, 850,5 mg/L, 479,3 mg/L, 8,5 mg/L. Based on the Regulation of the Minister of Environment Number 11 of 2009, the liquid waste has not met the quality standard. Wastewater Treatment Plant (WWTP) is needed to save reserves on cattle wastewater. The suitable installation in this condition is an initial settling basin, aerobic biofilter basin and a final settling basin. Aerobic biofilter is used so that liquid waste can be used biologically by using the media of honeycomb biofilter to grow and breed microorganisms. After processing the WWTP, there is a decrease in effluent, so WWTP can produce effluent BOD of 80,78 mg/L, COD = 198 mg/L, TSS = 5,10 mg/L, NH3-N = 23,9 mg/L and pH = 8,5.

After processing the WWTP, there is a decrease in effluent, so WWTP can produce effluent BOD of 80,78 mg/L, COD = 198 mg/L, TSS = 5,10 mg/L, NH3-N = 23,9 mg/L and pH = 8,5.","PeriodicalId":236511,"journal":{"name":"Jurnal Teknik Pengairan","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123118794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The physical hydraulic model carried out in the laboratory is intended to determine the hydraulic behavior of the flow in hydraulic structures. The aim of Hydraulic model test of Sakagilas Dam spillway is to determine the flow profile that occurs in spillway system, including flow depth, velocity, water flow pressure, and Froude numbers. Also to find out the hydraulic performance of side spillway design, transition channel, chute way channel, energy dissipator, and escape channel. Investigation of water flow pressure in the spillway system (side channel spillway, transition channel, and especially chute way channel) was measured and analyzed to determine the condition of structure safety against cavitation and vibration flow. The spillway of Saka Gilas Dam is a side channel spillway (Fixed+Gated) with an Ogee spillway. The shape of the side spillway is circular quarter circle (45⁰). Preliminary observations on the physical model test are carried out under the condition of Original Design, which if there is a poor flow hydraulic behavior, design modifications will be made. The design modification is intended to get the best flow hydraulic behavior, according to the standard design criteria for the side channel spillway system.
