Abstract

Geopolymer concrete is an environmentally friendly concrete that does not use cement at all, but uses high silica-containing materials such as fly ash (waste from PLTU). Geopolymer concrete consists of a binder material in the form of fly ash reacted with an alkaline activator solution, and filler material in the form of aggregate. The alkaline activator used is a solution of NaOH concentration of 8M and Na2SiO3 solution in a ratio of 1:2, while the ratio of aggregate and binder is 60%: 40%. In this study, the wetting treatment method was carried out with the number of test specimens for each variation as many as 3 test specimens and concrete compressive strength testing was carried out at the age of 3, 7, and 28 days on cylindrical test specimens with a size of 10 cm × 20 cm as many as 9 test specimens. Based on the results of the compressive strength test, the relationship graph between the compressive strength of concrete and the age of concrete is obtained, the value of the compressive strength of concrete with the wetting treatment method is 19.92 MPa

Abstract

The construction projects for Buildings C and D were delayed in construction process due to financial constraints in completing building construction and the project was re-implemented so that the two buildings were classified as Construction in Progress. Efforts are made to avoid obstacles by carrying out effective risk management. Therefore, all projects require proper risk management. On the basis of these events, risk management is carried out with the aim of knowing the risks that may occur, knowing the level of risk, and knowing the dominant risk response in the construction project of Buildings C and D of the Kalimantan Institute of Technology. The method in this study uses Severity Index method in analyzing risk variables with the Guttman scale used to determine the relevance of a risk variable. Then do an analysis of the response to the dominant risk. In the correlation test, 40 indicators were found that were relevant and 4 that were irrelevant. The validity test shows 7 invalid indicators. The results obtained are 6 indicators of risk that are dominant to the value of the likelihood and impact matrix labelled "high" risk. The risk response in this study is to seek supervision of the budget specified in the contract, carry out reliable material estimation calculations, the procurement department is required to identify places for replacement materials, make re-engineering arrangements for work execution sequences, and depend on professional distributors and forwarders, ensuring experienced project employees, working drawings have clear information, and prioritizing outdoor work.

Abstract

In the world of construction, aesthetic has become an important factor that must be considered. The aesthetic elements consist of wholeness, prominence and balance. However, aesthetic values can be influenced by several factors, namely economic, social, cultural, technological, ergonomic and psychological factors and this cause that in commercial development or the building that use slab system for foundation is used greatly affects it in terms of aesthetics and also cost effectiveness. The author's purpose of doing this research is to analyse the efficiency of volume in concrete and deflection between Flat Slab system and Waffle slab system. This research uses a case study at the Pasir Putih Convention, Batam, Indonesia. The analysis is done with ETABS software based on the local standards or known as Indonesia National Standard (abbreviated SNI). The choice of a slab system in a development is very important, especially if the building or construction is categorized as commercial structure. Based on the data obtained by researchers in terms of economics and deflection, Waffle Slab System is the right choice, meanwhile in terms of ease construction Waffle Slab System will be the secondary choice than Flat Slab, Since Flat Slab is more ease of framework installation than Waffle Slab.

Abstract

The Krueng Langsa River in Aceh often faces landslide problems due to natural erosion, human activities, and changes in river flow. This study aims to design a landslide mitigation system using geobags as a control technology on the Krueng Langsa Riverbank. Geobags, bags made of geotextiles filled with materials such as sand, are systematically installed to reinforce river banks. Primary data was obtained through field surveys, while secondary data was taken from related stakeholders, including regional maps and elevation data. The results of the study show that the installation of geobags along the 295 meters of the Krueng Langsa River bank can reduce the risk of landslides. The total calculation of the need for geobags reaches 9,440 units, which are designed to withstand flooding and strengthen cliff structures. In conclusion, geobags are an effective temporary solution in resisting erosion and waterlogging. This study recommends the development of permanent infrastructure for sustainable landslide control.

Abstract

Enggano Island is one of the areas in Bengkulu Province, located directly on the border with the Indian Ocean, making Enggano Island one of the outermost small islands in Indonesia. This island is one of the geographical areas where the soil contains lime, where limestone or what is often known as limestone is a non-metallic industrial mineral which has benefits as a raw material for cement, aggregate and asphalt. Considering that this island is a small island, it is very difficult to find mountain stone or river stone for Base A aggregate needs, because limestone is abundant on this island, this has encouraged researchers to conduct research on limestone as an additional material for fine aggregate in Base A. Research This aims to determine the CBR value after using limestone at 0%, 10%, 20% and 30%. CBR testing is carried out using the California Bearing Ratio (CBR) test method using a CBR penetration tool. The results of this research show that base A aggregate mixed with 0% limestone produces a CBR value of 94.84%, mixing 10% produces a CBR value of 95.34%. The addition of 20% produces a CBR value of 95.96%, and mixing 30% produces a CBR value of 96.62%. These results indicate that the addition of a limestone mixture as fine aggregate in base A can be used because the CBR value is greater than 90% and with the composition determined in this research

Abstract

ABSTRACT The bridge design modification presented in this study focuses on implementing a steel arch truss system combined with Fluid Viscous Dampers (FVDs) to improve structural efficiency and seismic resilience. The steel arch truss enables a longer main span with fewer intermediate supports, offering construction advantages, enhanced stability, and improved aesthetics. Additionally, the integration of FVDs aims to reduce structural displacements during seismic events, thereby minimizing potential post-earthquake damage.The object of this study is referred to as Bridge XYZ, assumed to be one of the key bridges in Gresik Regency, serving as a vital connection between Gresik and Lamongan. This bridge plays a strategic role in supporting mobility and logistics distribution in the region, making structural optimization and seismic mitigation essential. The research methodology includes data collection and literature review, followed by the structural redesign process. Structural modeling and analysis were conducted using SAP2000 software, adhering to Indonesian bridge and seismic design standards. The primary objective is to develop a single-span bridge configuration using steel orthotropic decks for a lighter superstructure and to evaluate the effectiveness of FVDs in reducing seismic-induced displacements. The analysis results show that the redesigned bridge utilizes BJ55 steel orthotropic deck plates with T-profile ribs, cross girders with WF profiles, tie beams with box girders, and Macalloy suspension cables. The application of FVDs successfully reduced seismic displacement by 3% to 45%, demonstrating their effectiveness in enhancing the bridge’s structural resilience.KEYWORDS Fluid Viscous Damper; SAP2000; Steel Arch Truss.

Abstract

One of the disturbances to road performance that can cause traffic flow conflicts is the entry and exit of vehicles on the roadway, vehicles stopping and parking, as well as vehicles decelerating. The main objective of this study is to determine the extent to which side friction affects the performance of the Boulevard lane. Observations were conducted on Saturday, Sunday, and Monday. Data collection was carried out through direct field observation to obtain data on side friction, traffic flow, and the average vehicle speed, with a 15-minute interval. The data were then analyzed using the PKJI 2014 method. After going through several stages of data analysis, it can be concluded that traffic flow has the highest correlation value (R²), with vehicle entry and exit on the roadway showing a value of 0.5122. Meanwhile, the relationship between side friction and the degree of saturation has a correlation (R²) of 0.947. The results of the analysis indicate that 94.7% of the changes in side friction significantly affect the degree of saturation.

Abstract

The use of environmentally friendly materials in road construction has received increasing attention, particularly in efforts to utilize waste as a value-added additive. One potential organic waste is candlenut shell ash, which contains specific chemical compounds that may affect the characteristics of asphalt mixtures. This study aims to investigate the effect of adding candlenut shell ash on the mechanical properties of Asphalt Concrete–Wearing Course (AC-WC) mixtures. The research method employed is a laboratory experiment with variations of candlenut shell ash content at 4%, 6%, 8%, and 10% of the total filler weight. Testing was conducted using the Marshall method to obtain values of stability, flow, Marshall Quotient (MQ), as well as VIM, VMA, and VFA.The Marshall test results indicate that the addition of candlenut shell ash influences the Marshall characteristics of AC-WC mixtures. At certain levels, the ash improves stability and flow values, demonstrating enhanced strength and stiffness of the mixture. However, at excessively high levels, the mixture performance declines. The optimal condition was achieved with 6% ash content, which yielded the highest stability and MQ values while meeting the 2018 Bina Marga specifications. Therefore, candlenut shell ash has the potential to be used as an additive in AC-WC mixtures, while also serving as an environmentally friendly waste management solution.

Abstract

One of the innovations that has received attention is Building Information Modeling (BIM). The software that applies the BIM concept is Autodesk Revit. This study compares the Cost Budget Plan (RAB) obtained through the BIM method, and the RAB calculated by conventional methods in the Denpasar Undiksha Campus Lecture Building Construction Project, to identify a more efficient method used in project cost estimation. The method used in this study is to collect project data in the form of structural work drawings, unit price analysis, and RAB, which is used as a reference for modeling with Autodesk Revit. The RAB calculated using the BIM method modeled on Autodesk Revit was obtained lower at IDR 3,003,134,274.71. while RAB was obtained from contract documents of IDR 3,425,386,712.44. The comparison between Autodesk Revit's RAB and the contract document RAB shows a difference of IDR 422,252,437.73 with an efficiency value of 12.33%. The Cost Budget Plan (RAB) generated through modeling using Autodesk Revit shows lower and more efficient values. This shows that the application of BIM methods in project cost planning can provide more accurate and optimal results
