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

Abstract

The objective of this research is to evaluate the characteristics of Asphalt Concrete–Binder Course (AC-BC) mixtures by utilizing coffee husk ash as a filler material. Coffee husk is an organic waste byproduct from the coffee bean processing industry, which has rarely been used in the construction sector. This study was conducted with variations of coffee husk ash filler proportions of 25%, 50%, 75%, and 100% of the total filler, and applied the Marshall test method to analyze stability, flow, VMA, VIM, VFA, and the Marshall Quotient. The test results indicated an Optimum Asphalt Content (OAC) of 5.25%. Mixtures with 25% and 50% filler content demonstrated performance that met the 2018 Bina Marga specifications, with good values of stability, VFA, and MQ, while the 75% and 100% variations showed a decline in quality. Coffee husk ash has potential as a substitute filler in AC-BC asphalt mixtures; however, its use is recommended not to exceed 50% in order to maintain the quality and performance of the mixture. The findings of this study serve as a reference for developing more environmentally friendly and cost-effective pavement materials.

Abstract

This study aims to test the durability of normal concrete after exposure to a combination of two extreme conditions: immersion in seawater and burning at high temperatures (300°C, 400°C, and 500°C). The study is motivated by the vulnerability of structures in coastal areas to both aggressive chloride attacks and fire hazards. The concrete used was designed for 25 MPa compressive strength and tested at 28 days of age. Cylindrical specimens (15 cm diameter and 30 cm height) were immersed in seawater for 28 days, then burned in a drum furnace for 30 minutes at the specified temperatures. Testing included compressive strength, density, and porosity measurements. Results show significant deterioration at 500°C, moderate deterioration at 400°C, and minor deterioration at 300°C. This confirms the need for better durability strategies for concrete in extreme environments.
