Abstract

Steel beams are susceptible to initial geometric imperfections due to improper fabrication and installation processes. Consequently, long steel beams without stiffening are prone to bending due to lateral torsion. The purpose of this study is to determine the effect of variations in the initial geometric imperfections of Single Curvature-Moment (SCM) on the moment, total displacement, displacement in the X direction (U1), displacement in the Y direction (U2), and twist. This study used an RH profile with a compact flange and web. The boundary condition used is a simple beam with an initial geometric imperfection due to single moment-curvature (SCM) bending. The variations used are the initial geometric imperfections values of SCM 0 mm (without initial geometric imperfections), SR5 (with initial geometric imperfections of 5 mm), and SR10 (with initial geometric imperfections of 10 mm). Initial geometric imperfections of SCM in steel beam decreased moment capacities up to more than 2% in elastic conditions and 12% in plastic states. This SR10 beam is also a beam that has a displacement of the X-axis (U1 = -203,960 mm), a displacement of the Y-axis (U2 = -255,615 mm), and the most significant twist (28,179 °). Keywords: Buckle, Initial Geometric Imperfections, Single Curvature-Moment.

Abstract

Surabaya–Gempol Toll Road is a toll that has operated since 1986, but in 2006 the Porong-Gempol route collapsed due to lapindo mud flow. Therefore, the toll road needs a relocation. On the construction of its relocation, additional scope of work was added and affected the feasibility of the investment which must be put into consideration for analyzing purposes in order to regain the initial feasibility value of 14.84% IRR. The forecast of cost and income analyzed with financial approach. The method used are Net Present Value (NPV) and Internal Rate of Return (IRR) with a discount rate of 11.8%. The result of investment feasibility after additional scope of work shows that the NPV during concession period (39 years) is negative Rp459.150.000.000,00 and IRR at NPV = 0 is 9,55%. To return the feasibility value, concession period is must be increase to 50 years with adjustment of the toll fee to Rp1.625 in 2021 and Rp1.980 in 2023. It shows that NPV is Rp1.037.727.000.000,00 and IRR at NPV = 0 return to 14,84%. Keywords: Additional Scope of Work, Compensation, Feasibility, Relocation.

Abstract

Infrastructures development in Indonesia is experiencing a high increase. However, many construction failures were due to construction that was not following the predetermined quality. Data obtained from the Investigation of the PNK Technical Team in 2013 contained 5 cases of construction project failure handled by the authorities with a total loss of more than 5 billion to the state. The reality shows that many construction service businesses have names but do not have the supporting facilities. Therefore, data collection aims to analyze the application of the ISO 9001: 2015 application quality management system and its application constraints. Processing data use descriptive statistical analysis and using SPSS version 25 software. The data testing techniques used include validity, reliability, and descriptive hypothesis. The data was collected using a questionnaire method for construction employees in the Design Project for the Tanjung Barat Station Flats. This analysis indicates that the application of the ISO 9001: 2015 quality management system by taking into account all the points from clause 4 to clause 10 is 85.19% and is in the excellent category (80-100%). Factors that become obstacles in implementing ISO 9001: 2015 are due to the lack of socialization regarding the application of ISO 9001, documented information, and communication between project teams. Keywords : ISO 9001, ISO 9001:2015, Quality Management System.

Abstract

The Government of Indonesia is accelerating the development of railway infrastructures. MRT is a milestone in the development of railway infrastructures in Indonesia since 2013. The elevated construction uses a single pier structure with a main reinforcement bar diameter of 40 mm. However, the conventional overlapping connection is unsuitable; hence it used a mechanical coupler connection. This research focused on the quality and cost comparison of using a mechanical coupler as a reinforcing connection in the MRT CP 103 Project's pier construction. The variables which would be studied were conventional connection and mechanical coupler connection. There were two stages in this research: quality testing in an independent laboratory and a cost comparison analysis. The data used were primary data from quality testing results, and secondary data were the project volume and unit price. The project sample in this research was MRT CP 103 Project with Pier AP 29 as the case study. The analytical approach used was descriptive analysis by making a comparison of the two variables. According to the quality test results, the tensile strength of the reinforcement was 665.56 N/mm2 and the mechanical coupler tensile strength was 626.33 N/mm2 . According to the calculation results of the case study on Pier AP29, it was found that the price difference was IDR2,246,622 or 6.17% cheaper than conventional connection. Further analysis showed that the mechanical coupler connection with 40 mm diameter was very effective because it was cheap. This research can be used as a reference in the alternative selection of reinforcement connection. Keywords : Quality, Cost, Mechanical Coupler, Pier, MRT CP 103 Project.
