Abstract

The basic concept of transportation is to facilitate mobilization from the Point of origin towards to the point of destination. One of element of that is quite important in transportation users that refer to the riders. It is need to be done a research about that to improve riding safety.This study used Traffic Conflict Technique method (TCT) Near-Missed Accident discovered and developed by Lund Swedish University. TCT refers to the relationship between road user behavior in the event of an accident generally be able to produce classifications Related to factors that cause a conflict or accident. This research conducted in Jambi City, at the junction connecting Jln. Sentot Ali Basa-Lrg. Marene-Jln. Raya Kasang Pudak-Jln. Lingkar Timur II. The location is quite representative with a focus of research, because the intersection has a fairly heavy volume of traffic flow, so that sometimes traffic jams and past violations often occur to the other cross.Based on results, the Average of Time to Accident (TA) that needed to evade or evasive for about 0,1 seconds; Whole conflict that is occurs included in the classification of Serious Conflict; the type of conflict that occurs is crossing and, from four conflicts that occurred at the location research on the majority of road users who are often involved in conflict Bentor riders who subsequently fall into the category of vehicle type motorized or MC.

Abstract

The increase in the need for building material of concrete for infrastructure need to be improved through technology inovation. Various methods have been developed to increase the compressive strength and flexural strength of concrete, one of them by adding micro reinforcement such as fiber. In this research, polypropylene fiber curved form is used. This research aims to analyze the influence of adding fiber into the design concrete mix on their compressive and fexible strength. In this study, the mix design used the SNI 7656-2012 method and the design compressive strength is 30 Mpa, the design slump height is 70 mm – 100 mm. Normal concrete is added with polypropylene with the composition of 3 kg/m3, 4 kg/m3, 5 kg/m3. 24 cylinder (15 x 30 mm) test objects are provided, and 24 beam (15 x 15 x 60 cm) test objects are provided, with 3 tests for each variety for the age of 7 and 28 days. Based on the test the compression strength results of normal concrete for the age of 28 days are obtained as 35.19 Mpa. Optimum value is obtained in the variety of 4 kg/m3, in the age of 7 days as 31,88 MPa or 15,74% increase, in the age of 28 days as 40.94 MPa or 16.33% increase from the normal concrete compressiven strength. The flexural strength of normal concrete aged 28 days is found to be 4.76 Mpa. The optimum value of flexible strength with the variety of 4 kg/m3, in the age of 7 days is obtained as 4,76 Mpa or 5,76% increase, in the age of 28 days is obtained as 5.87 Mpa or increase of 23.26% from the flexible force of normal concrete. Based on the results of this research, the adding of polypropylene fiber into the concrete mix can increase its mechanical properties, mainly the compression and flexible strength.

Abstract

Traffic control at intersections with a high volume of vehicle traffic requires regulation with traffic lights. With the regulation using traffic lights, it is hoped that it can reduce the number of queues experienced by vehicles, compared to those that do not use traffic lights. One of the intersections located in the Jambi City area which is equipped with vehicle traffic control using traffic lights is Hajj Dormitory Intersection. This intersection is a confluence of four arms of the road namely, Jl. H. Agus Salim – Jl. H. Adam Malik – Jl. H. Yunus Sanis – Jl. H. A. Roni Sani, located in the Handil Jaya Village area, Jelutung District, Jambi City. This intersection is a connecting road between regions including; office areas, shops, schools, markets, hospitals, campuses, tourist attractions, settlements, and various other destinations. At these intersections often experience traffic congestion problems, especially during the morning rush hour, afternoon rush hour and evening rush hour. This problem can be seen from the long queue of vehicles that occur. This study aims to analyze the traffic performance of the intersection, as well as obtain the service level of the existing intersection at the intersection of the Hajj Dormitory in Jambi City. The method used in calculating the analysis uses the 2014 Indonesian Road Capacity Guidelines for the capacity of the APILL intersection. The results of the study obtained several conclusions in the form of (1) the performance of the Jambi City Hajj Dormitory intersection, the existing conditions work less than optimally in serving the existing vehicle traffic flow, where the delay value that occurs is greater than 60 seconds/skr for all approaches. For Jl. H. Agus Salim the delay value is 74 seconds/skr and the queue length is 144 meters, Jl. H. Adam Malik delay value of 106 seconds/skr and queue length of 156 meters, Jl. H. Yunus Sanis the delay value is 134 seconds/skr and the queue length is 140 meters, and Jl. H. A. Roni Sani has a delay value of 228 seconds/skr and a queue length of 166 meters. (2) The service level for all approaches is F, where the delay value is greater than 60 seconds/skr. With an average intersection delay value of 116 sec/skr, the level of service F.

Abstract

Value Engineering is a function analysis approach that aims to reduce the cost of production or project. The amount of costs that will be needed both in the planning period and also the implementation and time saving process are sought not to increase the amount of cost itself. Gamil & Alhagar(2020) revealed that there are several impacts of Covid-19 in the construction sector, namely project suspensions, workers who lose their jobs, jobs that exceed the time limit, excessive costs, and financial impacts. Jallow et al (2020) stated the changes that must be made to the infrastructure sector in order to comply with health protocols and remain productive during lockdown. The problem in this study is how much the total cost savings can be obtained after Value Engineering method to the architectural work of the Facilities and Infrastructure Rehabilitation project at the Sungai Gelam Campground in the Hall Building. Through graphs and calculations is, the results of 4 work items with the highest percentage were obtained, namely on wall pair work, roofing work, floor formwork work, and frame, door and window work. At the creative stage, the idea of alternative replacements is given to the same quality, function and quality, but at a lower price. Then the analysis stage carries out the development of a comparison between the alternatives to be obtained. The recommendation stage is the result of the chosen alternative. At the recommendation stage, the result of applying the value engineering method is the Material used for the work of the red Masonry 5x11x22cm amounting to Rp.1,934,368.62 or 9.16% of the initial design cost. For Metal Tile Roofing Work of Rp.7,775,287.18 or 30.27% of the initial design cost. For Aluminum Frame, Door and Window Work, 8mm Glass is Rp.8,360,275 or 20% of the initial design cost. For Ceramic Floor Work measuring 40x40 cm (Plain) of Rp. 12,926,981.30 or 25.26% of the initial design cost. The cost efficiency that can be obtained using Rp. 30,996,912.10 or 6% of Rp. 514,217,599.92,- the total project

Abstract

Material is one component of the cost that plays an important role in supporting the success of a project. In the implementation of building construction projects, leftover materials or Construction Waste cannot be avoided. Excess material, whether from work results or from construction materials that are left/scattered/destroyed and cannot be used again, is called construction waste. Thus, a method is needed for the efficiency of remaining construction materials (Intan et. Al,2005). Construction in Indonesia currently has many problems regarding inefficiency in the implementation of construction. The causes of this inefficiency include poor performance, waste of resources used during the construction process, but this does not add value to the function of the resources used. Based on data submitted by the Lean Construction Institute (LCI), waste in the construction industry is around 57% and activities that provide added value are only 10% (Abduh, 2007). In construction projects, problems are often found in the construction process, such as changes to project drawings, changes to specifications, poor storage, and other technical problems in the field that cause material waste. Problems like this can have an impact on project cost losses beyond what was planned.Lean Construction is very necessary in construction projects so that waste does not occur due to the problems that have been explained previously, it is hoped that it can reduce waste on the project. So that it can reduce costs caused by waste and can establish better relationships between individuals involved in the project.

Abstract

Projects generally have a deadline, meaning that the project must be completed before or on time. In connection with this project problem, the success of a project can be measured from three things, namely, cost, quality and timeliness of completion. Many efforts must be made in order to achieve what has been planned, including calculating the correct strength of the structure, calculating cost estimates that are effective and economical. In implementing the construction of the Fiberline 3 Building (FL3B) & Relocation New Area Woodyard PT project. Riau Andalan Pulp And Paper indicated that there was a delay in the Excavation, Bacfilling & Cutting/Breaking Top Of Pile work, therefore the researchers accelerated it by rescheduling. This is intended so that this project can be completed according to the planned target. The method that will be used to speed up the duration of the project in this research is the Time Cost Trade Off method or also called the cost versus time exchange method. Based on the results of the Time Cost Trade Off Analysis on the Fiberline 3 Building project (FL3B) & Relocation New Area Woodyard PT. Riau Andalan Pulp And And Paper, it can be concluded as follows: Acceleration of project duration for the alternative of increasing overtime working hours by 4 (four) hours is obtained:The optimum time to accelerate the project duration is 142 calendar days with an increase in direct costs from Rp. 3,145,559,610.00 to Rp. 3,346,947,482.50. The total optimum project cost due to accelerated project duration increased from Rp. 3,806,175,528.10 to Rp. 4,007,523,400.60. Acceleration of project duration for the alternative of increasing the number of workers was obtained. The optimum time for accelerating the project duration was 142 calendar days with an increase in direct costs from Rp. 3,145,559,610.00 to Rp. 3,220,683,352.66 Total optimum project costs due to accelerated project duration increased from Rp. 3,806,175,528.10 to Rp. 3,881,259,270.76.
