The purpose of this study was to obtain the level of technical<br />effectiveness and the level of cost and time efficiency in the use of thin concrete and aggregate<br />grade foundation layers from the Mangkurawang-Rapak Lambur road improvement project<br />in Tenggarong District. Rigid hardening is determined as the closing pavement. Technically<br />the pavement plan design uses the 1993 AASHTO method while the 2017 binary analysis<br />method is used to compare costs and time. The results show that for a road improvement<br />project of 1,151 km with a subgrade CBR of 5%, the lower grade aggregate foundation B is<br />15 cm thick with a planned budget of Rp. 5,153,245,000.00 while the time required is 49 days.<br />Meanwhile for thin concrete 10 cm thick. With a budget plan of Rp. 6,147,623,000.00 within<br />43 days. Means the bottom foundation layer aggregate class B 16.18% more efficient with a<br />time of 12.24% more efficiency compared to thin concrete.<br />Keywords: lower foundation layer, thin concrete, AASHTO, binamarga analysis Rina Astuti, Wateno Oetomo ##submission.copyrightStatement## https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2849 Tue, 01 Oct 2019 00:00:00 +0000 ANALISIS PERBANDINGAN WAKTU PELAKSANAAN PEMBANGUNAN HARGA DAN ANTARA RUMAH SEDERHANA RUPAK DENGAN RUMAH SEDERHANA KONVENSIONAL TIPE 36 https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2852 One of the value engineering innovations in supporting a million housing program from the<br />Government which is supervised by the Ministry of Public Works and Public Housing on<br />housing or residential assistance for low-income people, PT Duta Cipta Pakarperkasa which<br />is engaged in the Steel Industry has issued a simple house product Rupak using the concept of<br />growing houses with knockable walls made from Expandable Polystrane (foam foam) coated<br />with steel plates. The purpose of this study was to obtain a comparison of the cost and time of<br />implementation in building a simple Rupak and conventional type 36 house, namely by using<br />a descriptive analysis method that was processed to determine the RAB and standards used in<br />Rupak houses and conventional houses. It turned out to be the result that for a modest house<br />it needed Rp. 80,898,797.52 while for conventional simple houses Rp. 92,471,372.31. And in<br />terms of time a simple house needs 16 days whereas a conventional simple house needs 29<br />days.<br />Keywords: shapely houses, conventional simple houses, styrofoam, knock down walls Aulia Sari, Wateno Oetomo ##submission.copyrightStatement## https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2852 Wed, 09 Oct 2019 00:00:00 +0000 ANALISIS CRASHING TIME MENGGUNAKAN MS-PROJECT DALAM PELAKSANAAN PEKERJAAN PADA PROYEK PENINGKATAN JALAN https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2854 The Sangkulirang-Bontang road improvement project is in the form of delays on the seventh<br />week of December amounting to 6.21%. The cause of the delay in the execution of work was<br />the problem of asphalt work and thermoplast road marking equipment. This research is<br />intended to obtain optimal solutions in order to catch up on project delays. There are two<br />alternatives that can be assessed, namely the first addition to the time of work<br />implementation using the amount of equipment available, and the second by increasing the<br />amount of equipment used. It turned out that the first alternative cost was Rp. 18,349,500.24<br />with a period of 17 days. The second alternative is the implementation cost of Rp.<br />36,699,234.86 but with a processing time of 9 days. Because the first alternative is cheaper<br />with time still permissible, the first alternative is chosen. In order to catch up on work delays,<br />planning and scheduling are obtained and the acceleration of the duration of the project<br />completion is 1 day from the initial project planning of 59.0%. And in terms of costs there is<br />a difference in the contract value of Rp.5,565,986,000.00 with a total cost of work of Rp.<br />4,647,256,026.19 or Rp. 505,998,154.81 amounting to 0.165%<br />Keywords: planning and scheduling project, delays, crashing time, road improvement Rina Mariani, Budi Witjaksana ##submission.copyrightStatement## https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2854 Thu, 03 Oct 2019 00:00:00 +0000 FAKTOR-FAKTOR YANG BERPENGARUH TERHADAP PERUBAHAN KONTRAK LUMP SUM PRICE MENJADI UNIT RICE https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2862 The work contract for the Surabaya-Gempol toll road relocation project Porong-Gempol<br />package 2 Porong-Kejapanan has been signed, namely in the form of a lump sum contract.<br />Due to a request from BPJT to change the design from 2 x 4 lanes to 2 x 6 lanes on the<br />Surabaya-Gempol toll road relocation project, Porong-Gempol 2 Porong-Kejapanan, the<br />contractor intends to propose a contract change from a lump sum to a unit price contract.<br />This study aims to determine and determine the factors that influence changes in the contract.<br />It turns out that by distributing questionnaires, it can be found that there are five main<br />variables, namely service users (X1), service providers (X2), third parties (X3), contracts (X4)<br />and environment (X5) that affect the final outcome of contract change (Y). By using factor<br />analysis and stepwise regression analysis aided by the SPSS program, it was found that only<br />the service user variable (X1) and the service provider variable (X2), which significantly<br />affected the contract change dependent variable (Y). And that influence is expressed by the<br />relationship Y = -1,171 + 0,268 X1 + 0,529 X2.<br />Keywords: lump sum contract, unit price contract,  factor analysis, multiple regression<br />analysis Abdulloh Abdulloh, Wateno Oetomo ##submission.copyrightStatement## https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2862 NALISIS MANEJEMEN RISIKO PEMBANGUNAN PROYEK JALAN LINTAS BAWAH TANAH BUNDERAN MAYJEN SUNGKONO SURABAYA https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2863 The underground road construction project in the satellite roundabout area is a project with<br />a risk level that is difficult to predict, so an in-depth risk management analysis is needed.<br />With the approach of the quality, cost and time specs, the dominant risk factors and changes<br />in costs and time will be sought due to the influence of these risk factors. By using 35<br />respondents, it turns out that the final results of the analysis show that from the aspect of<br />quality, the factor of planning changes, material lacking in quality, low productivity of work<br />tools becomes the dominant risk factor. While from the aspect of time, it turns out that the<br />failure factor of the team / project management, planning changes, and planning errors are<br />the dominant risk factors. Meanwhile, in terms of cost aspects of project management factors<br />and traffic safety, structural excavation, geotextile work, rigid pavement are the dominant<br />risk factors and from the natural aspect and planning aspects become the dominant source of<br />risk in terms of time and scope of structure work, general scope of work of in terms of cost. As<br />a result of these risk factors, it results in changes in costs for structural works of 75 million or<br />53%, while in public works amounting to 63 million or 11% with changes in time&gt; 30 days. <br />Keywords: Risk analysis, underpass, risk factors, sources of risk<br /><br /> Triase Triase, Risma Marleno ##submission.copyrightStatement## https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2863 Mon, 07 Oct 2019 00:00:00 +0000 ANALISIS PERCEPATAN WAKTU PENYELESAIAN PROYEK DENGAN METODE CRASHING DAN FAST TRACKING PADA PELEBARAN JALAN DAN JEMBATAN https://jurnal.untag-sby.ac.id/index.php/JSpTS/article/view/2864 To obtain a better profit without ignoring work safety and quality of work, the acceleration of<br />the implementation of the work of a construction project can be done using the Crashing and<br />Fast Track method. The research objective is to determine the amount of cost and time<br />incurred by the acceleration of implementation and determine the magnitude of the difference <br />in budget and time spent with the Crashing and Fast Track methods. The Crashing method <br />uses 2 types of variables, namely the addition of 1 hour, 2 hours and 3 hours overtime, and<br />the addition of heavy equipment and labor, while the Fast Track method uses 3 times the<br />overlapping application of work items. It turns out that the most optimal result is the addition<br />of 2 hours of overtime work for 163 days so there is a reduction in costs of Rp. 156,358,936,<br />while the Fast Track Method obtained the most efficient results are the results of operations<br />with a total duration of 130 calendar days, and with a total cost of Rp. 16,812,941,734,38,<br />while the difference between the total plan and the cost after Fast Track is: Rp.<br />340,933,265.63. The Fast Track method is cheaper than the Crashing method which uses<br />overtime hours for 2 hours.<br /><br />Keywords: acceleration of project time and cost, Crashing method, Fast Track method.
