One dimensional flow is often used as a flood simulation for the planning capacity of the river. Flood is a type of unsteady non-uniform flow, that can be simulated using HEC-RAS. HEC-RAS software is often used for flood modeling with a one-dimensional flow method. Unsteady flow modeling results in HEC-RAS sometimes refer to error and warning due to unstable analysis program. The stability program among others influenced bend in the river flow, the steep slope of the river bottom, and changes in cross-section shape. Because the flood handling required maximum discharge and maximum flood water level, then a steady flow is often used as an alternative to simulate the flood flow. This study aimed to determine the advantages and disadvantages of modeling unsteady non-uniform and steady non-uniform flow. The research location in the Kanal Banjir Barat, in the Semarang City. Hydraulics modeling uses HEC-RAS 4.1 and for discharge the plan is obtained from the HEC-HMS 3.5. Results of the comparison modeling hydraulics the modeling of steady non-uniform flow has a tendency water level is higher and modeling of unsteady non-uniform flow takes longer to analyze. Results of the comparison the average flood water level maximun is less than 15% Â (Â± 0,3 meters), that is 0.27 meters (13.16%) for Q50, 0.25 meters (11.56%) for Q100, dan 0.16 meters (4.73%) for Q200. So the modeling steady non-uniform flow can still be used as a companion version the modeling unsteady non-uniform flow.

There are plenty of buildings faliured in Indonesia until now. The process of collapse was caused of redistribution of moment happened in its structure not like its structural design. Building failured can be happened and caused by human activities, nature behavioral characteristic and combination of them. Refer the structural aspect, structural system is the first and prime element of building that supported building forever where man to live in. There must have strong efforts to analyze structural system as a whole building to provide safety factor, especially before construction have done. The point of view can be explained in planning, architectural design, engineering, economics, and environment. The last factor to avoid building failure consist of people or public participation and regulation of inspection periodically must be involved in building development processed.

To ensure sustainability of the benefits of water resources and water resources infrastructure for managing the funds should be provided adequately. Adequacy of funding for management can be planned based on the principle of full cost recovery or O & M cost recovery. One source of funding for the management of water resources as regulated in article 77, UU.RI Number 7, 2004 are the beneficiaries of which are service fees for water resources management (BJP-SDA). In order to realize the management of water resources with the principle of demand-side management and increase service fees for water resources management, it is necessary to analysis the correlation between the cost of management services to beneficiaries in accordance with existing regulations, commitment, and the contribution fee to be determined need to obtain agreement from interested parties (stakeholders) with the criteria that must be met. Important factors for the realization of cost recovery for water resources management in a basin area are: recovery policy management costs that will be done whether on the principle of full cost recovery or the O& M cost recovery, user groups according to water rights and the economic benefits derived each group of beneficiaries of development and management of water resources. Cost recovery model should be built at least with respect to these important factors. Keywords : cost recovery, users Â Abstrak Â Untuk menjamin kelestarian manfaat sumber daya air serta sarana dan prasarana keairan maka dana untuk pengelolaannya perlu disediakan secara memadai. Kecukupan danaÂ untuk pengelolaan dapat direncanakan berdasarkan prinsip full cost recovery maupun O&M cost recovery. Salah satu sumber dana untuk pengelolaan sumber daya air sebagaimana diatur dalam pasal 77, UU Nomor 7 tahun 2004Â adalah dari para penerima manfaat yang merupakan biaya jasa pengelolaan sumber daya air (BJP-SDA). Guna mewujudkan pengelolaan sumber daya air dengan prinsip demand-side management dan meningkatkan penerimaan biaya jasa pengelolaan sumber daya air, maka perlu dilakukan analisis korelasi antara biaya jasa pengelolaan dengan penerima manfaat sesuai dengan peraturan yang berlaku, komitmen bersama, dan besarnya kontribusi biaya yang akan ditetapkan perlu memperoleh kesepahaman dari pihak-pihak yang berkepentingan (stakeholders) dengan kriteria yang harus dipenuhi. Faktor-faktor penting untuk realisasi pemulihan biaya pengelolaan sumber daya air di dalam satu wilayah sungai adalah: kebijakan pemulihan biaya pengelolaan yang akan dilakukan apakah berdasarkan prinsip full cost recovery atau O&M cost recovery, kelompok pemanfaatÂ sesuai dengan hak atas air dan nilai manfaat ekonomi yang diperoleh masing-masing kelompok pemanfaat dari kegiatan pengembangan dan pengelolaan sumber daya air.

Time delay in the project execution phase causes cost escalation. This paper demonstrated the magnitude of severness of time delay affected to an increase of the project cost during the construction of bridge in Indragiri Hulu District. It wa evaluated that the project construction program was planned for 120 days but it was delayed up to 255 days. The time delay of 135 days within the project affected an increase of the constractorâ€™s additional expenses about Rp. 703 million. By simulating various parameters of risks, it was found that; (i) based on the â€œwhat it isâ€ scenario, 80 % probability the project was predicted to delay up to 118 days (cost of Rp 686 million); and (ii) by the implementation of risk management procedure encompassing 6 (six) risk mitigation elements it was estimated that 80% probablility of project delay may reach 46 days (cost Rp 361 million). The reduction of time delay and cost overruns may reach 50%.Â Hence, it demonstrates that the implementation of risk management procedure may control project risks systematically.

One of the problems with peat soils, when subjected to imposed loads of construction, is the very high compression and long-term excessive settlement. The embankment can be built on peat soil, but it needs reinforcement that can contribute to increasing the stability of the embankment. The nailed slab system, as reinforcement, is expected to reduce settlement and increase the stability of peat soil. The aim of this paper is to study the effect of pile length and distance on the reduction of settlement in both monolithic and non-monolithic piles. The embankment load test was conducted on 70 cm x 120 cm plates, which were reinforced pile with different lengths and distances in the peat soil layer. The analysis was conducted on the reduction settlement of monolithic and non-monolith pile. The results showed that the length and distance of the pile had an effect on the reduction settlement. Changes in pile length are more dominant reducing settlement compared to changes in pile distance. Pile connection with slab has a significant effect on different lengths of piles than different distances piles.
