Abstract

Analysis of the effect of the layout of reinforcement in reinforced concrete beams with different diameters to understand behavior and layout position of reinforcement produces the maximum of load capacity and ductility. Modeling and analysis using ANSYS program, the experimental test beam type OA1 and A1 from the University of Toronto (Vichio & Shim, 2004) was used as a benchmark and models which varies in layout of reinforcement. The number of models analyzed is a total of fourteen models consisting of seven models without stirrups and seven with stirrups. Beam behavior observed in the form of load capacity, deflection, ductility, stiffness and crack patterns. Results showed that: the layout of reinforcement affects the behavior of reinforced concrete beam; on the same width of reinforcedment, one layer reinforcement has greater load capacity and rigidity but smaller ductility than two layers; the layout of reinforcement in general does not affect the pattern of cracks; the collapse of the beam without stirrups is caused by the diagonal tension and  the beam with stirrups by shear and rupture due to the press; the layout of reinforcement produces the largest load capacity and ductility of the largest is model OA1 and OA1,4 on the beams without stirrups and models A1 and A1,5 on beam with stirrups.

Abstract

Degradation function of Situ Gede (Lake Gede) becomes crucial at present time compared to its function at initial condition when it was used for  tourism, irrigation, and raw water supply within an optimal use. The crucial aspects are related to the decreasing reliability of supply to Situ Gede and increasing sedimentation accumulation. The research concerns with various aspects due to the Situ Gede conservation and restoration that is aimed to increase the potential uses, based on the quantitative and qualitative model by using optimization technique and Analitic Hierarchy Process (AHP). The optimization technique is applied in order to evaluate the amount of monthly  water availability within 3 scenarios i.e. tourism ounly (Scenario 1), tourism and irrigation (Scenario 2), and, tourism, irrigation and raw water (Scenario 3), respectively, based on the potency of Situ Gede itself, new additional supply from other sources, and additional supply from Galunggung Crater. In addition, based on simulation of accumulated sedimentation model, that is aimed to identify the effect of firm outflow change of Situ Gede Release, indicates the decrease of firm outflow around 0,5% annually. The priority order based on AHP evaluation shows that the the first priority is Scenario 1, the second is Scenario 3 and the third is Scenario 2. Those priorities based on various criterias such as Investment Cost and Operation Maintenance, Additional Supply Reliability to Situ Gede, and Sedimentation. Sensitiviy analysis is also applied based on the weight change of each criteria in performing the shift possibilities due to the priority order.

Abstract

The flow-duration curve at a site is most useful tool for evaluating flows in water resources development projects. Flow-duration curves are based on cotinuous stream flow data, where stream flow meuserements are not available, precipitation and potensial evapotranspiration records can be used to calculate continuous flows. Calculation of monthly flows from meteorologic data are based on the water balance in watershed. The water balance equation is Precipitation – Actual evapotranspiration + Storage = Runoff. This calculation use coefficients that represent watershed characteristics, that will change from one watershed to another. The watershed characteristic coefficients changes will correlate with changes in vegetation, soils, and subsurface geology. This study is an attempt to estimate the watershed characteristic coefficients to calculate monthly streamflows in Krengseng River at Diponegoro Dam site. The  watershed characteristic coefficients analysis using F.J.Mock Model and NRECA Model. Resuls of watershed characteristic coefficients  analysis using F.J.Mock are, Expose surface, m = 50%, Soil moisture capacity, SMC = 200 mm, Infiltration factor, IF = 0.45, Recesion coeffisien, RC =0.70. Watershed characteristic coefficients using Model NRECA are, Index soil moisture capacity, Nominal:100+(0.25xmean annual precipitation), Base flow parameter, PSUB = 0.30 and Index groundwater storage, GWF=0.50.

Abstract

Banyak kota-kota di Indonesia terletak di kawasan pantai atau dataran banjir yang terbentuk dari endapan alluvialr. Ketika kota berkembang permasalahan penurunan muka tanah muncul akibat penambamhan beban bangunan yang meningkat yang diperparah oleh pengambilan air tanah yang berlebihan. Tulisan ini membahas dampak pengambilan air tanah yang berlebihan dan  peningkatan beban bangunan terhadap penurunan muka tanah di Kota Semarang. Berdasarkan kecenderungan pengambilan air tanah dan penambahan beban bangunan, potensi penurunan muka tanah ke depan dapat diprediksikan. Hasil prediksi menunjukkan laju penurunan yang cukup akurat dibandingkan dengan hasil pengukuran. Penurunan muka air tanah mempunyai pengaruh yang lebih dominan dibandingkan dengan penambahan beban pemabangunan terhadap penurunana muka tanah.Kata kunci:  groundwater abstraction, overburden load, land subsidencePermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3906[How to cite: Suripin, 2005, Contribution of Groundwater Abstraction to Landsubsidence at the North Coast of Semarang, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 2, pp. 27-36]

Abstract

The Feasibility study potential of small dams in Semarang District has identified 8 (eight) urgent potential small dams. These potential dams here to be constructed within 5 (five) years in order to overcome the problem of water shortage in the district. However, the government has limited funding source. It is necessary to select the more urgent small dams to be constructed within the limited budget. The purpose of the research is determining the priority of small dams construction in Semarang District. The method used to determine the priority in this study is cluster analysis, AHP and weighted average method. The criteria used to determine the priority in this study consist of: vegetation in the inundated area, volume of embankment, land acquisition area, useful storage, recervoir life time, water cost/m³, access road to the dam site, land status at abutment and inundated area, construction cost, operation and maintenance cost, irrigation service area and raw water benefit. Based on results of cluster analysis, AHP and weighted average method can be conclude that the priority of small dams construction is 1) Mluweh Small Dam (0.165), 2) Pakis Small Dam (0.142), 3) Lebak Small Dam (0.134), 4) Dadapayam Small Dam (0.128), 5) Gogodalem Small Dam (0.119), 6) Kandangan Small Dam (0.114), 7) Ngrawan Small Dam (0.102) and 8) Jatikurung Small Dam (0.096). Based on analysis of the order of priority of 3 (three) method showed that method is more detail than cluster analysis method and weighted average method, because the result of AHP method is closer to the conditions of each dam in the field.

Abstract

Nowadays, the government plan to develop toll road intercity network, which connect Jakarta and Surabaya city, Either Roadway or toll road that connecting one town to another represent supporting tools towards economic activity. Lacking in road connetion services, can cause high expense economics which finally encumber society as a whole.  In the last decade, government find difficulties to increase road connection service, either from capacities or also from its qualiaty side. Recent years, the maintenance cost allocation seems to short to fulfill the requirement standard of maintenance. Therefore the toll road constructed by private sector should be mobilize as one of the society participation form in the infrastructure development, besides reduce the monetary burden to government. It is need to learn furthermore, whether the toll road construction oppose against the principle of environment conservation. Principles of sustainable development also consider to the economics aspect. Both aspects, economic and environment have to be considered and in line together. In evaluating a big project, there are some method which could direct or indirectly calculate its cost benefit. Its should be recognized whether the toll road construction comply with the financial, economics and social aspects. In the view of economics, toll road construction investment could mobilized a big amount of money and offering many vacancies. While in economics critism which produce a high unemployment, it should stimulate the growth of economics in a broad way. Meanwhile government should not be encumbered to make such road improvement, which is very difficult to fulfill nowadays.Keywords: toll road investment, community participation, sustainable developmentPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3939[How to cite: Riyanto, B., 2006, Pengembangan Jaringan Jalan Tol antar Kota dalam Perspektif Sistem Transportasi Berkelanjutan, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 1, pp. 95-105]
