Abstract

This paper discuss the concrete hydration thermal control with the economical and eco-friendly Method Statement, based on the basic perfomance of concrete bio-admixture, Bioconc, which is produce mico-filler, reduce the binder content up to 40%. The concrete hydration thermal sources is from the cement as binder, since Bioconc may reduce up to 40% binder content, the concrete hydration thermal can be controlled and worked as Low Heat Concrete. The paper limited discuss about the application of the Bioconc,for laboratory scale trial mix, Low Heat Concrete mock up modelling test and comparison with another 2 (two) Low Heat Concrete above mentioned [1] , [4] and does not discuss the Bioconc ingredient. The research started by laboratory scale trial mix Fc'25 Low Heat Concrete Bioconc based concrete Job Mix, from cement content reduction 20%, 25%, 30% and 40%. The attached result shows optimum jobmix is Fc'25 Low Heat Concrete Bioconc based concrete Job Mix on 40% cement as binder content reduction, was choosen as Low Heat Concrete Mix Mock Up. Later on, further research make mock up for sampling mass concrete dimension 1000x1000x2500 mm3 was executed. The attached Graph Thermal Monitoring Low Heat Concrete shows that the peak temperature occured 63,5 ?C in 29,5 hours after pouring and maximum thermal differential between LHC layers is 19,5 ?C. Another two Low Heat Concrete Method Statement, i.e.: Pre-cooling and Low Heat Concrete with Fly Ash 40%, Mock Up Graph Thermal Monitoring also attached for comparison study. The observation and analysis proof that, “Low Heat Concrete Hydration Thermal Reduction with Bioconc” is work simplifier and economically, for mass pouring. The most essential thing is that, the basic concept of Bioconc’s Low Heat Concrete on reducing the mass concrete cement-binder content means reducing CO2 emision in every concrete production, without any hazard impact to the environment. Its mean Bioconc based Low Heat Concrete contribute to develop the green technology and eco-friendly technology on the concrete industry as sustainable green technology.

Abstract

The road network is a land transportation infrastructure that plays an important role in the transportation sector, especially for the balance of the distribution of goods and services, both from other regions. In this study, an analysis was conducted to find out how the influence of heavy vehicle volume increase on the service life of the road, while the method used was Bina Marga, the study was conducted by taking a case study on the Hera road section until Dili. This research is expected to find out how the service life of the road if the volume of heavy vehicles continues to increase. If the% of heavy vehicles increases, the thickness of the required surface layer will also be even greater. When% of vehicles or carrying heavy traffic loads are increased, the thickness of the existing layer cannot meet, because the calculation results with% of heavy vehicles increase by 10%, surface thickness 17.2 cm / This will cause the service life of the road to decrease because it is confirmed that the road will be damaged before the service period ends due to excessive load increase in heavy vehicles.

Abstract

The complex problems that existed during the Field Implementation in the SMP Negeri 1 Surabaya project at that time caused some work that was not as planned both in terms of time, quality and cost which resulted in overbudget and overtime. When experiencing overbudget and overtime, it is necessary to have good cost, quality and time management. Good management should not only be owned by the project owner. The length of time to complete the project has a big effect on the increase in the overall project cost. Therefore, daily, weekly and monthly progress reports are needed to report work results and completion times for each project work item. Furthermore, this work is compared with the completion time of the plan so that the completion time can be controlled for each period. This is because the construction of the building has a delay in time so that it can cause disruption in some field operations. The analysis that I have done is viewed from all of them (owner and contractor). This study uses the AHP (Analytical Hierarchy Process) research method because AHP is used to derive the ratio scale of several paired comparisons that are discrete or continuous. Other problems such as inconsistencies in planners, supervisors, executors, and other authorities in the field, namely lack of communication and late making decisions such as changes in design and changes in calculations that are in implementation and planning so that the project results in time and cost delays, and other problems. such as material calculations and others, there are also delays caused by delays in making decisions in implementation. Because of that, the project for the Public Junior High School 1 in Surabaya experienced delays in several jobs, namely the foundation, column, ladder, and beam work, which should have been done in 1-2 months to 3-4 months. In terms of implementation, such as lack of communication between planners, supervisors and implementers as well as other authorized officials, a good communication is needed. So that it does not cause so many problems and can reduce delays in terms of implementation in the field.

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%.
