Abstract

Plastic waste, which is one of the biggest environmental pollutants, can open up opportunities to be utilized in the field of highway construction because it is easy to obtain and has a more economical price as a porous asphalt mixture. Referring to this, a research was carried out on the characteristics of a mixture of porous asphalt with polyethylene terephthalate (PET) plastic waste as an additive to asphalt. The purpose of this study was to determine the effect of the use of PET plastic waste on the characteristics of porous asphalt mixtures. The method used is a laboratory scale experimental method based on 3 types of testing, namely marshall, cantabro loss and asphalt flow down. The gradation in this study used the open graded Australian Asphalt Pavement Association (AAPA) 2004. The test results showed that the addition of PET could improve the performance of porous asphalt mixtures. Stability, density, MQ, and VFA values increase with the addition of PET content so that they can prevent fractures due to traffic loads. The decrease in the cantabro loss value makes the mixture's resistance to disintegration better. addition of PET content up to 7.5% can reduce the flow value so that the mixture has optimal flexibility. However, the recommended PET content should be below 5% because in this study the penetration and ductility values did not meet the general specifications for 2018 Highways.

Abstract

The base course material uses mountain stone which is broken up with a stone crusher so that it has a high quality which makes it expensive. In this research we need an alternative material to replace fine aggregate that meets the specification requirements. One of the more affordable resources is sand aggregate. The purpose of this study was to determine the density and comparison of the California Bearing Ratio (CBR) value of the base course using sand as a substitute for fine aggregate. The method used in this research is laboratory scale testing to obtain data on aggregate characteristics, optimum moisture content, and CBR values. The base course aggregate mixture used was 55% coarse aggregate and 45% fine aggregate consisting of a mixture of fine crushed stone and 0%, 10%, and 20% sand substitution. The results showed that the KAO value decreased with the addition of sand aggregate. Laboratory CBR values increased with 0% sand substitution having a CBR value of 99.2%, 10% sand substitution having a CBR value of 90.6%, and 20% sand substitution having a CBR value of 84.1%. Only the laboratory CBR value with sand substitution of 20% does not meet the specifications for base A aggregate, namely a minimum value of 90%.

Abstract

Increased community mobility needs to be followed by the provision of transportation services that are tailored to the needs of travelers. To adjust to these needs, it is necessary to know the preferences of travelers in choosing the mode and level of service required by travelers. This research discusses the problem of choosing a mode of transportation between the royal-class Damri bus and the Lampung-Jakarta route plane. The purpose of this study is to determine the characteristics of travelers and the factors that influence mode selection, determine the probability of mode selection, and determine the condition of the Damri bus service level and the Lampung-Jakarta airplane route. The analysis carried out was multiple linear regression analysis with data from the results of distributing questionnaires to travellers, then a probability analysis was carried out using a binomial logit model. The results of the study show that there are factors that have an individual significant effect on the choice of mode, namely tariffs/costs, travel time, and level of security. The probability of choosing a mode for airplanes is 62% and for Damri buses is 38%. The service quality of the two modes has not been maximized, this can be seen from several passenger complaints, including Damri buses still using regular ship services, and the airplane fares that are imposed are expensive.Key words : characteristics, travelers, mode selection, probabilities. Peningkatan mobilitas masyarakat perlu diikuti dengan penyediaan layanan transportasi yang disesuaikan dengan kebutuhan pelaku perjalanan.

Abstract

A level crossing is a form of an intersection where a railway line crosses a highway at the same level. This may result a long queue which is caused by changes in velocity and density of vehicles. Hence, research should be conducted in order to determine changes in vehicle velocity which occurs when the gated crossing is opened on that road section. One of the level crossings between the railway line and the highway can be found on Jalan Hos Cokroaminoto, Kebon Jahe, Tanjung Karang. This study aims to determine changes in traffic velocity that occur on Jalan Hos Cokroaminoto based on the equivalent of light vehicle (EKR) value obtained from the headway ratio method. The results of the observation show that the average velocity of vehicle when crossing the railway line is 3.12 km/hour, while when entering the crossing is 19.48 km/hour so that there is a decrease in velocity in the amount of 16.36 km/hour.Keywords: Shock Wave, Light Vehicle Equivalence (EKR), Rasio Headway Method, Greenberg Method

Abstract

This research aims to investigate the influence of implementing BIM concepts on waste material analysis in type 1 and type 2 column reinforcement. Type 1 column reinforcement refers to the reinforcement applied on each floor separately, while type 2 column reinforcement refers to the reinforcement applied every two floors. In this research, the BIM concept is implemented using Autodesk Revit software. The research process begins with data collection, 3D structural modeling, reinforcement modeling, inputting reinforcement schedule marks, clash detection, outputting the Bar Bending Schedule (BBS), cutting lists, and waste material analysis.  The research findings indicate that the total weight of type 1 column reinforcement requirement is 29319.17 kg for D16 and 10232.06 kg for Ø10, with a total weight of waste reinforcement is 2739.17 kg for D16 and 120.64 kg for Ø10. Meanwhile, the total weight of type 2 column reinforcement requirement is 32103.36 kg for D16 and 10232.06 kg for Ø10, with a total weight of waste reinforcement is 6350.03 kg for D16 and 120.64 kg for Ø10. The waste level of type 1 column reinforcement is 9.34% for D16 and 1.18% for Ø10, while the waste level of type 2 column reinforcement is 19.78% for D16 and 1.18% for Ø10. Based on the research findings, it can be concluded that type 1 column reinforcement is more effective and efficient compared to type 2 column reinforcement in terms of the weight requirement and waste generated.

Abstract

The rapid development that occurs in the construction sector is important because the construction sector is an important part of the development of a country. The rapid development and high level of project complexity require construction service providers to work more effectively and efficiently. Currently, the development of technology and communication science is able to answer these problems, one of which is by using Building Information Modeling (BIM), which facilitates a more integrated design and construction process in order to obtain efficient results. Stages of research methodology: 1) Preparatory stage; 2) Data collection stage; 3) 3D modelling stage with Autodesk Revit; 4) Clash Check examination stage; 5) Stage of releasing work volume; 6) Stage of preparing The Cost Budget Plan (RAB); 7) Stage of drawing conclusions and presenting results. Overall, the total price difference between the total price using the total volume of work contained in the Bill of Quantity (BoQ) results in a greater total price than using the total volume of work produced by Autodesk Revit, with the following indicators: There is a calculation error in the form of human error in the process of preparing the RAB using the total volume of work contained in the BoQ by planning consultants, such as material double-count errors. From this research, it can be concluded: 1) Modeling with Autodesk Revit greatly speeds up planning work because it is very complex to be applied to various construction projects; 2) The use of BIM is very efficient due to the full-integrity facility; and 3) Output volume issued can minimize human error in calculating work volume manually. Minimizing human error greatly affects the contractor's profit.

Abstract

Earthquake resistant buildings are not designed only by strengthening the resistance of the structure, but are also designed to reduce earthquake forces. One of the structural reinforcement elements that can reduce earthquake forces is shearwall. The variation of shearwall layout will have a different effect on the performance level of the structure. This study aims to determine the performance level of the structure with a variety of shearwall layouts in a building structure model using the pushover analysis method. Determining the level of structural performance using pushover analysis is carried out using the help of structural analysis programs based on SNI 1726-2019, SNI 1727-2020, SNI 2847-2019 and ATC-40. From the research results it was found that the structural performance level according to ATC-40 (1996), for model 1 and model 6 were included in the damage control category, while for model 2, model 3, model 4 and model 5 were included in the immediate occupancy category. Placement of shearwall which has the optimum value according to ATC-40 for the X direction occurs in model 2 with the shearwall installed in an L shape which is placed near the center of mass of the building. Whereas in the Y direction it occurs in model 3 with the shearwall installed in an L shape which is placed away from the center of mass of the building. Key words : shearwall, model, structure performance level, pushover analysis.
