Abstract

Selorejo dam is located in the village of Pandansari, Ngantang Sub Regency, Malang Regency. It is located in Kali Konto, a tributary of the Brantas River. Selorejo dam has a very important function, especially for the purposes of hydroelectric power generation and irrigation. As an old dam, completed in 1970, Selorejo experiences a decreasing volume of its reservoir due to a high sedimentation rate. The decreasing volume Selorejo reservoir has impacted the function of the dam and it is important to formulate a better operating rule to optimalize the current volume. During the planning of the operating rule of Selorejo reservoir, Perum Jasa Tirta I as an operator of the Selorejo Dam use a dependable discharge in predicting inflow discharge. This study predict the inflow discharge using ARIMA forecasting method, which then used to formulate a new operating rule. This study used 10 years of 10 days period inflow discharge data, which 9 years of it used to generating the ARIMA model and the last 1-year data for calibration. The study result suggest that the best ARIMA model in predicting the dam’s inflow discharge is ARIMA (1,1,1)(2,1,1) 36. Compare to a current method, this model is proved predicts better inflow discharge which has smaller Relative Error (KR) to the real data (Model’s KR 5.5 and Operator’s KR 17.8).Keywords: ARIMA, inflow discharge, the operating rule of reservoir, reservoir of Selorejo Dam.

Abstract

Karang Anyar outlet channel has the outlets that directly flow in to the sea and it’s influenced by the tides. Flooding often occurs when rain along with high tides. The outlet channel has a very gentle slope,initial data mentioned that outlet channel length is approximately 1625 m, elevation in the upstream = +4.40 m and +0.10 m in the downstream, with an average slope = 0.003. Elevation embankment upstream = +6.00 m and downstream = +1.50 m. Meanwhile, according to secondary data, the flood with 10 th years return periode that flow in the outlet channel is 66.4 m 3 /sec and the flood with 25 th years return periode is 75.16 m 3/sec. On average, a tide water level is +1.5 m above sea level. Based on the variety of modeling, the action concepts that can eliminate the flooding are these following action: widening the channel dimension, build the embankment on channel side, making the local storage for each sub-catchment in the downstream, making the gate for the local storage, making tidal gate to prevent the tide come into the system, making the retarding basin to accommodate flood waters from upstream when the outlet is closed due to high tide.Keyword: Outlet channel, Regional arrangement, Outlet, Karang Anyar, Tarakan

Abstract

Water availability is a major problem to be considered in determining cropping patterns in irrigated areas. Considering the importance of irrigation activities, there should be plan an optimal utilization of water in order to get maximum benefit from the existing water supply according to their function. Irrigation area of paguyaman is planned with two doors intercepts. Irrigation Area Paguyaman on right side, is planned to irrigate 4,176 ha of land where still have potential in the irrigated area expansion. Potential expansion of irrigated area is 1500 ha. Paguyaman Irrigation Area is still in the implementation stage of physical construction. The approach used as the basis arrangement for the water distribution is the approach in terms of a balance between the availability of water to the water requirements for crops. Allocating and distribution of water required in an integrated calculation attended by using a Linear Program.Key words: Optimization, Irrigation Area, Linear Program, Solver.

Abstract

The Oebufu Village geologically composed of limestones that hydrological growing in this area should be karst hydrology, but at this location, shallow groundwater are found in dig well at 5.63 m to 25.26 m depth, that are not commonly found in karst area. Therefore, the study aims to determine the spatial model of shallow groundwater in the study area and its controlling factors. Geoelectric equipment used to determine the presence of aquifer, IPI2WIN and RES2DINV software used to analyze the results of geoelectric, while the Surfer software used to create the shallow groundwater aquifer spatial model. The results of the study provide the output of the spatial model of shallow groundwater; controlling factors of the shallow groundwater are: (a) lithology, a soluble form of limestone and formed the secondary porosity; (b) the rock exposed, exposed rock thickness determines the depth of the aquifer; (c) hydrological system, is different hydrological system between the back and the foothills; and groundwater conservation zones covering the entire study site. Making watertight septic tank to accommodate domestic waste is a groundwater pollution control efforts in Oebufu Village, that its geological formation were limestone.Key word: Spatial model, controlling factor, shallow groundwater, conservation zone, Oebufu Village

Abstract

In the hydrologic analysis activities, the Errors in basic hydrological data monitoring in a drainage area of the river will result in data are not correct and lead to the result of planning and management of water resources is not efficient and effective. The errors are usually caused by a number of rainfall stations in the watershed inadequate and dispersal patterns of uneven rainfall stations. The purpose of this study is to obtain the results of the evaluation of the amount of rainfall stations WMO standards based on existing conditions, to determine the comparison between the design flood discharge KaganRodda method and the design flood discharge conditions using the existing station network, and to obtain recommendations amount and location of rainfall stations positions. This study conducted in watershed of Limboto, with an area of watershed is 902.91 km2 .The results of this study are recommending 16 rainfall stations where the 4 stations is the existing stations, with each station rainfall density is 8.038 km.Keywords: Flood, Kagan-rodda, Rain Station, Rain Station density.

Abstract

Sorong City where is located in West Papua Province has often experiences flooding due to overflow of Remu River. This study aims to find the proper flood management alternatives through hydrology, hydraulic, and economy approach. Based on hydrology analysis with Log Pearson III method, the highest historical rainfall that ever occured is the rainfall with return period of 16 years, that is 224.2 mm. The HEC RAS 4.1. simulation results n value of 0.021 with relative error of 2.64%. The proper flood managements are dike and retarding basin and the both of the alternatives use return period of 25 years. Dike has been choosen as then proper alternative with total ranking of 0.53 based on priority scale determination using Analyrical Hierarchy Process method with technique, economy, and easy implementation considerations.Keywords: Flood, HEC RAS, Analytical Hierarchy Process, Dike, Retarding Barsin.

Abstract

The potential of water resources Bone is the source of life for the people of Gorontalo, especially as a source of water, supply fresh water for the people of Bone Bolango. Generally in upstream of watershed use less water than the water right of it downstream, and the areas generally utilize water higher than the water use right. Excess use of water in downdstream will take from the remaining water rights of upstream. Because of these problems, it is necessary to study type of management system in related with conditions of watershed. System of incentives / disincentives is a form of integrated watershed management. The purpose of this study are to investigate the discharge quantity is used by the stakeholders, determine the required operational discharge in conservation the watershed, and establish the policy in watershed management with a system of incentives / disincentives.Keywords: Water Right, Incentives, Disincentives

Abstract

The problems occurred at the Kangkungan-Pohijo are not available surface water irrigation needs. BPP FT-UB as a community service agency conducting a relief estimating groundwater flow wich is done to determine potential for subsurface flow. If found potential of groundwater, useful to development irrigation potential so increasing harvest productivity. The aim of study is determine locations which have groundwater flow potential to support pump irrigation. The result of this study shown that point 4 is the best potential of groundwater flow than other location. This location was also its existence still on the region of “bengkok desa”, so it is recommended as the first alternative. The point-2 was recommended as an a second alternative. The response of residents of Pohijo village was very enthusiastic in order to realize procurement pump groundwater.Keyword: aquifer, transmisivity, resistivity, vertical electrical sounding, configuration
