Abstract

Column play an important role in bulding structure,remembering column failures wil improve the overall structure.other structure,column structural element that are vulnerable to completion failure recive earthquake loads.The structure of this bulding is located in jayapura,including in KDS D with a value of = 0,9 and =0.96 .From the result of structural analysis to the column evaluated,then the dimension of K1 100/100 (28D36,D25-100 mm , D25-150 mm and 8 D25-100 mm) K2 120/120 (28D32, D25-100 mm,D25-150 mm and 8 D25-100 mm) ,K3 130/130 (28 D 32,D25-130 mm, D25-150 and 8D25-130 mm),K4 140/140( 28 D32,D25-130 mm,D25-150 mm and 8D25-130 mm), column WF792x400x30x40, WF 800x400x30x40, WF 808x400x30x40, WF 900x400x30x40 with efficient columns such as column K1 100/100 with low prices Rp Rp.23,065,074,774.000.After analyzing the structure of a tiered bulding using the SRPMK method,it is expected to remain earthquake resisitant and have economic efficiency values

Abstract

A construction project is a series of activities carried out with a specific scope of work, time and expense according to the agreement between the project owners and the contractors. In the case of a project, it is necessary to file a task so that it can run smoothly and carry out according to plan times. An optimum time and expense analysis of the job involved time cost trade off for case studies of the advanced construction of the tower's 1 (one) located on the campus of ITS Sukolilo - Surabaya. Analysis runs to speed up project time that is tardiness with minimal costs added and should be noted on the other hand that the emphasis on activities that are on critical trajectories and have the lowest cost slope on those tracks. Steps made in this acceleration are identifications of job activity, arranging network diagrams, specifying acceleration scenarios, crashing duration and crashing cost, calculating cost slope, and do the iteration phase. After a time cost trade off analysis, it would provide output with multiple time and cost alternatives to the new project. Of the many alternatives, selected the time and expense of the completion of the project optimum. From the analysis, to complete the work at completion time according to plan, the cost increased by IDR 474.268.897,00 from IDR 9.919.982.348,00 to IDR 10.394.251.245,00 with a 32 day reduction from 180 days to 148 days so that the project could be completed as expected on March 2, 2021.

Abstract

Generally, a basement construction requires an appropriate Earth Retaining Wall to support the development process in the area. In the project area of ??PT. UBS Surabaya has the construction of a Soldier Pile which is arranged from Bored Pile and Bentonite Pile, the construction applies the Bottom Up and Dewatering method which means that construction starts from the subgrade level firstly and then the construction work goes up. This research was aimed to examine the existing types of retaining wall (Soldier Pile) with an alternative comparison of Corrugated Concrete Sheet Pile (CCSP). This is aimed to finding the effectiveness retaining wall that has been used with another methods so that it can affect to management in terms of cost and time which has been taken. Based on the comparison result of two methods, it is found that the use of the Soldier Pile method has a cost difference of Rp. 139,533,000,- less than the Sheet Pile method. However, the implementation time of the Sheet Pile method is 28 days faster than the Soldier Pile method, with this comparison, the Sheet Pile method is considered more effectively applied with an implementation time effectiveness ratio of 36.36% considering that the development project area is close to densely populated settlements.

Abstract

Cement is a product that is needed in the construction of infrastructure and various kinds of buildings. The function of cement as an adhesive material in the building construction makes cement have a vital position for people. Therefore, cement producers must pay attention to the quality of cement produced to fulfill the cement supply in accordance with development needs, either quantity or quality. There are many cement producers and brands in the market, makes people have many choices of cement products that can be used. This study aims to examine the quality of Gresik cement on cement users in Rungkut District, Surabaya. The research method used is descriptive quantitative research. Data was collected by spreading questionnaire to 79 cement users who are construction workers in Rungkut District, Surabaya. These data is then processed by applying descriptive statistics supported by SPSS for Windows version 20.0 program. The results reveals that the quality of Gresik cement was categorized as good. The highest quality perceived by respondents is reliability, followed by conformance to specifications and product performance. Meanwhile, aspects that are perceived as lower by users are durability, aesthetics, and additional features.

Abstract

In planning and controlling a project, it is often faced with various obstacles, for example, there is a shortage of materials, errors in the work order. In this project there was a delay due to a pandemic which caused the project to be hampered which initially could run according to schedule but became not according to the specified schedule. To minimize the impact of risks that occurred, a project scheduling method was developed using a probabilistic duration, one of which was PERT ( Program Evaluation and Review Technique). In this study, PERT (Program Evaluation and Review Technique) simulation was implemented which was implemented in the Grand Shamaya basement construction project based on the optimistic, pessimistic, and possible durations obtained from the survey results by the project management. PERT calculation using Microsoft Project 2013 software which produces an optimistic duration of 530 days, then for a possible duration of 535 days, a pessimistic duration of 551 days, and finally for a simulation result duration of 534.6 days. The difference in the schedule for the basement construction project of the Grand Shamaya Surabaya apartment when compared to scheduling using the PERT (Program Evaluation and Review Technique) method is the length of duration and the probability of project completion. So the duration of the plan schedule for 535 days produces a probability of 53.19%.
