Abstract

Dalam suatu kondisi pemilik proyek menginginkan proyek selesai lebih awal dari rencana semula dikarenakan rumah dinas tersebut akan segera ditempati oleh karyawan RS. Ibnu Sina sebelum pergantian tahun 2018, akan tetapi terdapat keterlambatan pekerjaan, Oleh karena itu diperlukan analisis penjadwalan proyek sehingga dapat diketahui berapa durasi percepatan yang dapat dilakukan agar proyek tersebut dapat diselesaikan tepat waktu. Penelitian ini menggunakan metode CPM (Critical Path Method), percepatan durasi kegiatan hanya dilaksanakan pada pekerjaan yang kritis saja dengan target waktu penyelesaian sesuai kontrak awal pekerjaan. Berdasarkan hasil analisis penjadwalan ulang (rescheduling) dengan metode CPM (Critical Path Method) dihasilkan kesimpulan bahwa waktu yang dapat dipercepat ialah 25 hari kalender dengan durasi total pelaksanaan 66 hari kalender. sedangkan apabila tidak dikendalikan maka waktu penyelesaian sebesar 91 hari kalender. Kata kunci: CPM, percepatan, reschedulling

Abstract

Banjarsari Highway is an arterial road in the primary road network system that connects Surabaya, Krian, Sidoarjo, Mojokerto and Lamongan areas. Banjarsari-Cerme Highway uses flexible pavement consisting of basic soil layer, bottom foundation layer, top foundation layer and surface layer. The arrangement of these layers is generally used on roads that have a fairly high volume of traffic. Over time, the number of vehicles passing is increasing and eventually causing road damage in a relatively short period of time. Therefore, it is very important to make road improvements in accordance with the Average Daily Traffic Volume (VLHR) and the composition of passing vehicles. This study will calculate and plan the type of pavement that is feasible according to the age of the planned plan. To supporting this study, several data are needed such as: traffic volume data, rainfall data, CBR data, and secondary data obtained from the Public Works Office and Gresik Regency Transportation Office. From the data obtained, it is then processed and analyzed on the calculation of pavement bending new roads with Bina Marga standards. Planning in this study uses flexible pavement analysis in accordance with the Guidelines for Thick Planning of Pavement Pavement with Component Analysis Method (SKBI-2.3.26.1987) and combined with AASHTO method 1993. The results of this study are: (1) The average daily traffic (LHR) based on the age of the 10-year plan on Banjarsari-Cerme road is 29,418 vehicles per day. (2) The thickness of the planned bending pavement on Banjarsari-Cerme road in Gresik regency based on the analysis method of the 1987 Bina Marga SKBI component of 97.50 cm with the following details: a) Surface layer (surface course) used Laston MS-744 with a thickness of 17.50 cm with details of a wear layer AC-WC 7.50 cm thick and foundation layer AC-BC as thick as 10 cm. b) The base course is used 100% CBR 100% grade with a thickness of 35 cm. c) The bottom foundation layer (subbase course) is used sirtu (class B) CBR 50% with a thickness of 45 cm. Keywords: Average Daily Traffic, Bending Pavement Layer, Component Analysis and AASHTO Method.

Abstract

The implementation of a construction project is a mechanical series of activities or works that are complex, multi-layered and interdependent. Building construction activities in the field of construction, we need a basic means of calculation of Principal Unit Price Analysis (AHSPK). Contractors are more likely to calculate the price of the work unit based on their own analysis based on previous experience in completing a construction work, although it is inseparable from SNI analysis (Indonesian National Standardization). The research method in analyzing the Budget Plan (RAB), namely the SNI and Contractor Calculation Methods. From the calculation of each analysis of the existing budget plan, the results obtained are a comparison of the budget plan between the SNI method with the Contractor Method. A more economical cost budget plan using the Contractor Method is IDR 548,564,455.00 while the results of the analysis of the SNI cost budget plan is IDR 1,151,860,112.11. Keywords: Budget, Comparison, Contractor, Cost, Estimation, Price, SNI.

Abstract

Structural design is an important element in the construction of a building in order to produce a strong, safe and economical building. Overall, the building structure consists of two parts, namely the upper structure (in the form of floors, beams, columns, walls and roofs) and the lower structure (in the form of foundations and sloof beams). Columns and beams are the structure of the building frame, therefore it is very important, so that dimensions and use of reinforcement that are safe and economical must be planned. Changing the function of an office building into a café building needs to recalculate the beam and column structure. In the load regulation, the live load value of café buildings is greater than that of office buildings, so it is necessary to recalculate the dimensions of the beam and column structures so that they are able to withstand the existing loads in the cafe building. This study analyzes the beams and columns of concrete structures using a load-bearing frame system with tools from the STAADPro program according to SNI-2847-2013 regarding structural concrete requirements for buildings. The conclusion of this research is that the beam section uses a size of 300 x200mm and the column section uses a size of 300 x 300mm. Column section uses 8 Ø12 bending reinforcement, the support beam uses 2 Ø12 upper reinforcement 3 Ø12 lower reinforcement, field beam uses 7 Ø12 upper reinforcement 4 Ø12. Keywords: Analysis, Beams, Columns, Concrete, Structure.

Abstract

Warehouse is a building to store a variety of necessary products for a company, it could be said that warehouse is collection point and starting point of the goods that will be distributed to the retailer or directly to the consumer. In cases that took place at the warehouse in PT.X is a building which had height of 26 meters and span of 25 meters that has earthquake-prone and wind loads. This makes researcher need to do structure analysis and planning of warehouse resilience of PT.X in Gresik.This study uses SNI 1726:2012 for planning earthquake resistance of building and non-building structures. The step of structure analysis of rafters, gordings, beams and columns as follows: 1. Input data into STAAD pro (structure modelling), 2. Control the strength of rafter structures, gordings, beams and columns using the largest external force data based on calculations from STAAD pro.The results of this study are: 1. The structural resistance to combined loads according to SNI 1726:2012 shows an indication of the inability of the steel profile on the H 350 x 175 rafter and on the H 250 x 125 beam with the actual value of the allowable ratio more than 1.00, 2. The rafter profile is replaced with I 450 x 175 x 11 profile which has a ratio value of 0.7818 and the beam profile is replaced with H 250 x 250 x 9 x 14 which has a ratio value of 0.1996, both steel profiles have indicated pass result. Keywords: Analysis, STAAD Pro, Steel, Structure.
