Abstract

The behavior of prestress pretension beams made of Reactive Powder Concrete (RPC) concrete with compressive strength above 120 MPa included in the Ultra High Performance Concrete (UHPC) classification was investigated to study the mechanical properties of concrete and the performance of prestressed beams against static load tests. The mechanical properties of RPC materials include concrete compressive strength, concrete tensile strength, concrete elastic modulus values and concrete density compared to 70 MPa High Strength Concrete (HSC) concrete. Curing concrete at an early age using high temperature hot steam (steam curing) ensures the development of the compressive strength of concrete. Experimental tests were carried out on 4 pretension beams designed to be used as highway bridge beams, namely beam #1 (30/50-HSC-NF-S); beam #2 (30/50-RPC-F-S); beam #3 (17/50-RPC-NF-S); beam #4 (17/50-RPC-NF-S). The mechanical properties of RPC concrete show superior values compared to HSC concrete. From the results of the static test, only beam #3 (RPC beam which does not use steel fiber in mixing) which shows a value of flexural resistance below the theoretical value due to brittle destruction that occurs in the beam. Steel fiber effectively maintains beam integrity thereby maximizing bending resistance, preventing explosive brittle destruction, and preventing concrete fragmentation during peak loads.

Abstract

Mikrotrans is a means of transit that supports Transjakarta buses and serves residential neighbourhoods. However, travellers have lodged several concerns about the mikrotrans service's facilities and infrastructure. These concerns include drivers failing to stop at bus stops, drivers driving at excessive speeds, facility damage, inconvenient passenger wait periods, and a lack of bus arrival information. Aside from that, the bus stop lacks operational information, the bus stop pole is damaged, and the distance between bus stops varies. Using the customer satisfaction index approach and IPA-Kano integration, this study examines the operational performance of the Jak Lingko mikrotrans in terms of user satisfaction. The research findings revealed a 71,61% user satisfaction index in the satisfied group. However, all assessment attributes have negative gap values, resulting in a satisfaction score that fails to match user expectations. Based on the IPA-Kano integration analysis, three fatal category qualities were identified as high priority for service improvement. The fatal category attribute is that the driver drives the vehicle if the passenger is seated and/or both of the passenger's feet have touched the ground (A7), the vehicle's stopping time is adjusted to coincide with the completion of the passenger boarding and alighting process (A14), and there is signage, route information boards, the bus name, and the bus stop number (A22).

Abstract

The condition of the road pavement is an important aspect in terms of determining road maintenance and repair activities. In order to evaluate the condition of the road pavement, it is first necessary to determine the type of damage, the cause, and the extent of the damage that has occurred. Construction of a road that is not accompanied by good maintenance will cause various kinds of problems. Many district/city road pavements in Central Kalimantan have suffered damage as a result of repeated traffic loads, in line with increasing economic growth in these areas, including one of them on the Pulang Pisau – Pangkoh Road Section as far as ± 57.5 Km which is located in Pulang Pisau Regency, Central Kalimantan Province. So that on this road research will be carried out on the remaining existing road services to be able to provide alternative solutions for handling existing road problems and also budget plans. The method used in this study is using a FWD (Falling Weight Deflextometer) to determine the condition of the road structure. In addition, to find out how to handle it, this study used the 2017 Pavement Design Manual. Comprehensive road survey vehicles typically consist of a FWD mounted on a heavy truck together with a ground-penetrating radar and impact attenuator. The results obtained from this study are the remaining life of the Pulang Pisau – Pangkoh road section of 17% x UR (about 3-4 years). For its handling, it uses a flexible pavement overlay which was previously covered with selected fill and requires a cost of Rp. 243.905.730.000,- or Rp. 6.097.643.250,- per Km.

Abstract

Environmental and social risks are risks that can disrupt the sustainability of infrastructure provision through the PPP scheme. PPP is a cooperation scheme involving many stakeholders and each stakeholder can be part of mitigating risks, including environmental risks. Environmental risk mitigation can be carried out through instruments and frameworks owned by each stakeholder. This research aims to map the ESG framework that exists in PPP schemes in Indonesia based on existing instruments for stakeholders to be able to make ESG an effective instrument for mitigating environmental and social risks. The research method used in this research is qualitative because the analysis used in this research is a descriptive and in-depth observation of the PPP ecosystem in Indonesia. The results of this research show that there are eight stakeholders in PPP in Indonesia. Each stakeholder has an instrument and can apply the ESG framework based on the instrument they have. Implementing the ESG framework can mitigate environmental and social risks in business processes carried out by stakeholders in the PPP ecosystem in Indonesia.

Abstract

This study discusses geopolymer-reinforced concrete beam's shear strength capacity by experimental observation using high-calcium fly ash as the main binder. This study observed the influence of shear span per effective depth ratio due to the geopolymer concrete beam's shear behavior and strength capacity. Two beams are designed to have diagonal tensile cracks; hence the shear failure state could be obtained. Each beam has similar properties by 150 mm in width, 250 mm in height, 1800 mm in length, 2D16 as the flexure bar reinforcement, and stirrups of Ø6-250 with 20 mm concrete cover. The research employed the four-point load bending testing with the load span difference of each beam, which will later be the study variable. The things sought in this study include the peak load-deflection curve, the shear capacity that occurs in geopolymer concrete beams, and the shear capacity comparison with ACI 318-19. The results of the tests that have been carried out show that type A geopolymer-reinforced concrete beam was more ductile than type B beams, with a percentage difference of about 21.49% in deflection. The shear strength at the ratio a/d of 2 was 115,04 kN, and the ratio a/d of 2.5 was 89,00 kN. As well as a comparison of the shear strength of the test results with calculations according to ACI 318-19 shows a ratio of 1.69. So it can be concluded that ACI 318-19 calculations were conservative.

Abstract

Jakarta has a high level of urbanization, which causes land use changes and increasing inundation problems. One area that has experienced inundation is North Kembangan with a height of 20 - 30 cm in recent years and so of that the location is included in flood-prone sub-districts. Accordingly, a study is needed to estimate the North Kembangan drainage system actual conditions using the rainfall-runoff transformation model. This study simulates using the Storm Water Management Model (SWMM), and the calibration validation process is accomplished using the Nash-Sutcliffe model efficiency coefficient (NSE) and root mean square error (RMSE) method to evaluate the reliability of the model. The calibration for several model parameters is required to obtain the reliability model, including the channel Manning coefficient, land overflow Manning coefficient, and curve number. The calibration result shows that NSE values are 0,65, and the RMSE is 0,051 based on data in 2021. Then the validation result shows the NSE is 0,62 and RMSE is 0,040 based on data in 2022.

Abstract

This numerical analysis study predicts the behavior of spun piles with and without concrete infill under cyclic flexural loading and constant axial load. A fiber section using STKO pre- and post-processor for the OpenSEES program was employed. Spun piles were modeled using displacement-based beam-column elements with distributed plasticity and cyclic loading procedures with displacement control. The numerical method proposed for this research was verified by comparing it to reliable experimental results.

Abstract

This paper explores the accuracy of nonlinear finite element procedures implemented in ATENA in predicting the load-drift response of reinforced concrete coupling beam with headed bars under reversed cyclic loading. In this study, one of the coupling beams incorporating headed bars, tested by Seo and co-workers in 2017, is analysed and its response at different lateral drifts is discussed. Parametric analyses, studying the influence of reinforcement layouts, are also presented. It is shown that the hysteresis loops of the coupling beam could be predicted accurately, along with the crack patterns at different stages of loading and failure mode. It is also shown that the omittance of headed bars resulted in more pronounced bond-slip effects and a more severe pinched response in the post-peak region, highlighting the importance of providing adequate headed reinforcement. A similar trend was observed in the coupling beam with the omittance of U-bars and horizontal transverse reinforcements, whereas stirrup relaxation was found to increase the prominence of shear failure.

Abstract

Traffic accidents are unexpected and undesirable incidents that occur on the highway, resulting in damage and casualties. Traffic accidents occur due to several contributing factors, including driver behavior, road conditions, technical errors in vehicles, and environmental conditions. Based on several studies, motorcycles are the vehicles most frequently involved in traffic accidents. Jember is one of the districts in East Java with a high number of motorcycle accidents. Based on data from 2017 to 2019, motorcycle traffic accidents in Jember reached 3,543 cases. Most of motorcycle riders involved in accidents in Jember are young riders. Young riders are considered to lack proper driving attitudes. This study was conducted to determine the relationship between driving behavior and accidents in Jember District among young motorcycle riders using structural equation modeling (SEM). The primary data used were survey results with respondents consisting of motorcycle riders aged up to 24 years old residing in Jember District. There is also supporting data in the form of accident data that occurred in Jember District from 2018 to 2022. Using that method, the results showed that driving behavior variables significantly influencing traffic accidents are traffic violations and stunts. The traffic violations variable has an influence of 0.840. Meanwhile, the stunts variable has an influence of 0.267.
