Abstract

Total population increase therefore water supply requirement, irrigation water, as well as requirement ofresidential areas are also increase. Many ways in development of water resources management arerequired to fulfill future water requirement, and need minimizing land use changes. Integrated waterresources management planning based on river basins is required. Polices for water resourcesconservation program, exploitation of water resources and control of the water’s destructive force arerequired for optimizing water resources management. A holistic water resources management is requiredfor protecting, maintaining as well as increasing the value of water resources. According to WaterResources Law No. 7 year 2004, a water resources planning for a river basin has to prepare withparticipation of some stakeholders. Many program alternatives of water resources management will beproduced from a water resources management planning process. Thus, the ranking analysis of alternativeprograms needs to be proceeded. Decision Support System (DSS) with weighting optimization model is atool for helping to determine the rank of water resources development programs. The DSS technique needscriteria as basic for prioritizing water resources development programs. Determination weight for eachcriterion and score for each alternative water resources development program are required. Applicationof this model is a priority analysis of water resources development program from JRATUNSELUNA riverbasin for administration district Jepara, Kudus and Demak

Abstract

The Wonogiri Reservoir capacity decreases rapidly, caused by serious sedimentation problems. In 2007, JICA was proposed a sediment storage reservoir with a new spillway for the purpose of sediment flushing / sluicing from The Keduang River. Due to the change of reservoir storage and change of reservoir system, it requires a sustainable reservoir operation technique. This technique is aimed to minimize the deviation between the input and output of sediments. The main objective of this study is to explore the optimal Wonogiri reservoir operation by minimizing the sediment trap. The CSUDP incremental dynamic programming procedure is used for the model optimization.  This new operating rules will also simulate a five years operation period, to show the effect of the implemented techniques. The result of the study are the newly developed reservoir operation system has many advantages when compared to the actual operation system and the disadvantage of this developed system is that the use is mainly designed for a wet hydrologic year, since its performance for the water supply is lower than the actual reservoir operations.Doi: 10.12777/ijse.6.1.16-23 [How to cite this article:  Wulandari, D.A., Legono, D., and Darsono, S., 2014.

Abstract

Drainage problems, especially in the cities of Indonesia has become important with the frequent occurrence of  flooding or water logging in the rainy season at urban areas that disrupt people life and obstruct transportations fluency and cause property losses in large enough quantities. The main cause of flooding or water logging is a change from the natural landscape into the development environment, hence, increasing impermeable surfaces, such as roads, parking areas, sidewalks, and residential areas. This change reduces, disrupts, or eliminates the natural vegetation, land surface, basin, and natural drainage pattern that prevents, vaporizes, stores, issues slowly and absorbs the rainwater. The impact of changes in the landscape of OASIS Area of PT. Djarum Kudus is the increasing direct runoff (run off) while reducing water seep into the ground so that it can make the puddle of water. In its planning, the hydrologic analysis using the 15 years of rainfall data in Sta. Kedung Gupit is performed. In hydrologic analysis of this planning is applied the probability distributions of Log Pearson type 3 and is used EPA SWMM program with 10-years return period of flooding, thus, it is obtained the maximum flood discharge before construction in the amount of 9.05 m3/second and the maximum flood discharge after development in the amount of 16.69 m3/second. Based on the results of that analysis, the planning of drainage canals is carried out. In the planning, the used drainage canals are new drainage canals which are constructed at the OASIS area of PT. Djarum Kudus. The dimensions of the drainage canals that are used vary from the largest with the dimension of 2.5 m x 3 m and the smallest with the dimension of 0.6 m x 0.6 m. Furthermore, to determine the effectiveness of the drainage canals, it is modeled using HEC RAS program. In the calculations using that program, all the canals that are planned in the OASIS area of PT. Djarum are currently able to accommodate water during the flooding for return period plan of 10 years. Planning areas OASIS Drainage System PT. Djarum Kudus produces The dimensions of the drainage canals that are the largest with the dimension of 2.5 m x 3 m and the smallest with the dimension of 0.6 m x 0.6 m. The construction of drainage canals at OASIS area of PT. Djarum Kudus takes time for 4 months with a total cost incurred is 9,490,131,000.00 (nine billion four hundred and ninety million one hundred and thirty-one thousand rupiahs).

Abstract

Simpang Lima area of Semarang is administration region, education residence, service, and industry which are constructed in the center of Semarang sub district. Center Semarang region is an area where is topographically flat. Industry development, trade, and rapid growth people bring Simpang Lima are of Semarang as the prominent center growth of Semarang city. In addition flood happened in region of Simpang Lima area of Semarang is caused by the lack of drainage performance, high sedimentation, and not yet maximum in flood control using provision of water pumps. There are some scenarios to solve that proble,. the first scenario is by fixing the channels in Simpang Lima are of Semarang in order to increase the capacity of channel flow. This way includes widening the channel, fixing the slope of bottom channel, and scanting the discourtesy of channel flow wall. Second scenario is by making new channel in Simpang Lima cycle, because of the difficult to rehabilitate the existing channel which locates under sidewalk of Simpang Lima cycle, so taken solution to make new channel. The new channel locates under the road of Simpang Lima cycle and uses closed channel type. The third scenario is by maximizing the capacity in Kartini Pump Station. Hope by maximizing the capacity of pump may fasten the process of water disposal from Kampung Kali River to Banjir Kanal Timur River and reduce water level in Simpang Lima area of Semarang drainage channel downstream section.
