Abstract

ABSTRACTJakarta MRT was one of solution to solve the traffic jam in Jakarta. There are two physical constructions which serves as the main infrastructure of Jakarta MRT, elevated and underground track. It is not only the first MRT in Indonesia but also, the first large-scale underground works in Jakarta. The physical construction of underground structure became an interesting case to be researched. The use of precast concrete tunnel lining (PCTL) segment was necessary to hold the loads and to provide the space for underground track.In designing the tunnel lining, calculation of the member forces and safety check are necessary to determine the amount of rebar and the dimension, and also to know the value of safety, so, the tunnel lining can be used as the function. According to the guidelines for the design of shield tunnel lining issued by International Tunnelling Association (ITA, 2000), the member forces of tunnel lining could be calculated by (1) Elastic Equation Method, (2) Bedded Frame Method, (3) Finite Element Method (FEM). In this research, the member forces of tunnel lining are calculated using analytical method, without computer program. Therefore, method (1) is used to know the value of each member forces to be used for designing the reinforcement bars. The member forces are analysed for tunnel lining with 6.8 m outer diameters, 1.5 m width and 0.25 m thickness in Jakarta MRT CP106 (Bundaran HI).Based on research which has been done, obtained the maximum values for positive bending moment in the tunnel crown (θ = 0°) is 101.352 kN.m, for negative bending moment in the tunnel axis (θ = 90°) is -281.394 kN.m. In contrary, the value of maximum axial force is in the tunnel axis (θ = 90°) is 1094.538 kN, for minimum axial force is in the tunnel crown (θ = 0°) is 904.674 kN. While, the value of maximum shear force is in (θ = 120°) is 118.740 kN, for minimum shear force is in (θ = 30°) is -66.866 kN. The result of safety checks against member forces in tunnel lining, the value of nominal bending moment multiplied by reduction factor (ϕ · Mn) is 296.263 kN.m, bigger than the value of ultimate bending moment (Mu) is 281.394 kN.m. For the value of nominal shear force multiplied by reduction factor (ϕ · Vn) is 136.095 kN, bigger than the value of ultimate shear force (Vu) is 118.740 kN. While, safety check against thrust force of shield jack obtained the value of maximum compressive stress of concrete segment (𝜎𝑐) is 5.016 MN/m2, bigger than the value of allowable stress (𝜎𝑐𝑎) is 16 MN/m2.Keywords: Jakarta MRT, underground, tunnel lining, member forces, Elastic Equation Method.

Abstract

ABSTRACTA hospital is one of the important elements in the people of nation, especially in the medical sector. Cideres hospital is one of hospital in district Majalengka that has the best services. Healthy is important to make development of quality people sector. Cideres hospital has a target to make Majalengka become a healthy district in Indonesia.As one of citizen needs, healthy is important to make development of quality people sector. Cideres hospital has a target to make Majalengka become a healthy district in Indonesia. After this building constructed, it make the service healthy to the people in Majalengka more increase.In order to create a structure that is safe and meets serviceability limit, in the process of design the building structure must be according to SNI-2847-2013 of reinforced concrete, which are the latest regulations adapted from the latest material technology development refers to the AISC. Besides planning, the loading structure must be according to SNI-1727-2013 and the calculation of earthquake engineering refers to SNI-1726-2012.With the special programs, the completion of structural analysis for various purposes can be performed quickly and accurately, when compared with the structural analysis is done manually including SAP2000 program.Keywords : Analysis and design, SNI codes, SAP2000 Program

Abstract

ABSTRACTThe pile foundation is one of a kind of deep foundation that serves to funnel structural loads to hard soil layers that have a high carrying. The purpose of this study was to calculate the bearing capacity of piles.Based on SPT data obtained and calculated by Mayerhoff method at point BH-01 Qult = 259,992 tons, at point BH-02 Qult = 258,234 tons, and at point BH-03 Qult = 279.586 tons, with HSPD data obtained based on reading dial pressure manometer tool is approximately from 178,365 tons - 186,120 tons, whereas with PDA obtained based on RMX value on PDA test is about 124 tons - 225 tons.The results of the calculation of bearing capacity there are differences in values, both from the use of calculation methods and the location of points reviewed. From the results of the calculation can be concluded that the big highets bearing capacity the pile is values of SPT. In values of HSPD and PDA is relative same because the method using similar method (hydraulic and wave method).

Abstract

ABSTRACTRivers drain water by embracing a gravitational philosophy, in which water always flows from high to low or downstream to downstream. The process of river water flow is an endless natural process, closing the hydrological cycle by restoring the river runoff to the sea. For centuries, rivers have been used as a source of clean water, meeting human needs for drinking water, sanitation, irrigation, and so on. Large rivers are dammed to store water in the wet season and use it in the dry season for various purposes.Kali Gung or Kaligung or also known as Kaligung river is a river that flows in Tegal regency, Central Java. This river is one of the largest rivers in Tegal besides Kali Ketiwon and Kali Kemiri. This river is called Kali Gung because it is tangent to the spring that comes from Mount Agung is an ancient name from Mount Slamet in pre-Islamic times in Java. Upstream or spring water Kaligung located in the north of Mount Slamet and empties to the north precisely in the sea of Java.Keywords: Hydrologycal cycle, rivers, downstream, upstream, Kaligung.
