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.

Abstract

This paper presents the shear behavior of concrete beams incorporating glass fiber-reinforced polymer (GFRP) stirrups using a nonlinear finite element simulation package, 3D-NLFEA. The experimental data was adopted from the test results performed by previous researchers. The constitutive model for the concrete material used in this simulation is based on the plasticity-fracture model and considers the tension-stiffening effect of the concrete. The numerical simulation result was compared with the experimental test, including the ultimate shear force-deflection response and cracking pattern. Based on the analysis result, it was found that the ultimate shear force-deflection response shows almost the same. For the mean ratio of prediction ultimate shear load to actual ultimate shear load from the experimental result and a coefficient of variation of 1.000 and 0.206%, respectively, and deformation results, the mean ratio of prediction deformations for the mid-shear span and mid-span of 0.966 and 0.941, respectively, with the coefficient of variation for the mid shear span and mid-span of 11.849% and 7.627%, respectively. However, the cracking pattern mode of the beam shows good results, which complies with the experimental test.

Abstract

With the increasing frequency of trains, more and more people are becoming interested in using them for transportation. However, at Gubeng station, the majority of passengers still prefer to use private vehicles or online transportation instead of public transportation. To evaluate passenger satisfaction with intermodal services at both the new and old Gubeng stations, a performance analysis was conducted. Data analysis uses quadrant analysis with the gap analysis method, the Importance Performance Analysis (IPA) method, the Customer Satisfaction Index (CSI) method, and the Fishbein method. From the results of the analysis, a total of 303 respondents were obtained. In the Gap Analysis method, negative values were obtained for all attributes. The overall service satisfaction index using the Customer Satisfaction Index method obtained a satisfaction index of 0.523 with the criteria "quite satisfied". The overall attitude value of the Fishbein method was 417.335, the criteria for a "neutral" attitude value.

Abstract

This research aims to study the impact of supplementary cementitious materials on the heat of hydration of concrete. The experimental tests were performed for concrete with three size variations and seven variations of supplementary cementitious materials (SCMs) to investigate its impact on the heat of hydration. The SCMs used in this research mainly come from industrial waste materials. Fly ash (FA), ground bottom ash (GBA), and silica fume (SF) were the waste materials used in this research. Tests were carried out for seven days for each variation to observe the effect of volume changes and the addition of SCMs on the change in concrete temperature. The experimental results indicated a direct correlation between concrete volume and maximum temperature, with notable variations in temperature distribution across the concrete mass. Typically, the highest temperature was observed at the core of the concrete. Fly ash (FA) and bottom ash (BA) demonstrated an inverse relationship between their content as supplementary cementitious materials (SCMs) and the maximum temperature achieved. Increasing the proportion of FA and BA in the concrete mixture resulted in a reduction of the hydration temperature. Additionally, silica fume (SF) was found to accelerate the hydration rate, though its efficacy in lowering the heat of hydration was significant only when its content exceeded 5%.

Abstract

Natural fibres are biomass waste that agriculture generates in abundance. Lacking environmental awareness, biomass waste is often improperly disposed of. This raises environmental concerns. Natural fibres might be used as building materials, such as bricks. This might be a viable alternative for sustainable development. In this study, articles on the use of natural fibres in bricks are reviewed. The purposes were to study their influence on the structural behaviour of fibre-reinforced bricks and to identify their prospects and challenges. Natural fibres were found to reduce the brick's density, drying shrinkage, thermal conductivity, and workability. They boosted the compressive, tensile, flexural, and tensile splitting strengths, as well as the water absorption capacity. Natural fibres can only be used in limited amounts in bricks, usually less than 5%. This prevents significant strength loss and excessive water absorption. This study points out the drawbacks of natural fibres, such as inconsistent properties, dimensional changes, combustibility, decay susceptibility, and microbiological growth susceptibility. These shortcomings should be addressed before commercialising fibre-reinforced bricks. To overcome the problems, natural fibres may need to be carefully screened and treated before being used in bricks.

Abstract

Surabaya City has several public transportation such as Feeder Wira Wiri and Suroboyo Bus managed by Surabaya City Government, Bus Trans Semanggi managed by the Ministry of Transportation of the Republic of Indonesia, and Bus Trans Jatim managed by East Java Provincial Government. Based on observations in Purabaya-Rajawali routes, these public transportation services have yet to achieve maximum integration between modes, hence requiring analysis to improve the integration and connectivity of these public transportation systems. This analysis assesses customer satisfaction regarding the integration and connectivity of Feeder Wira Wiri, Suroboyo Bus, Trans Semanggi Bus, and Trans Jatim Bus along the Purabaya-Rajawali routes in Surabaya City. The methods used Customer Satisfaction Index (CSI) to calculate user level of user satisfaction and Quality Function Deployment (QFD) used by integrating Importance-Perfomance Analysis (IPA) and Kano model. From the analysis results, the satisfaction level indicates a value of 68.01% (satisfied). So, it is needed to improve existing attribute integration. From this analysis, 11 technical responses were obtained to improve integration attributes. The final result of this research indicates that 11 improvements of integration attributes can be implemented in the integration system between services of Feeder Wira Wiri, Suroboyo Bus, Trans Semanggi Bus, and Trans Jatim Bus in Surabaya City Purabaya-Rajawali routes.

Abstract

The durability of concrete is an essential factor in construction as a means to enhance the quality of public facilities planning. The durability of concrete structures can be degraded due to several factors, one of the factors is sulfate attack concrete. Expose to magnesium sulfate (MgSO4) causes more aggressive damage compared to sodium sulfate. The negative effect of sulfate exposure is the accelerated formation of microcracks that lead to concrete deterioration. This study aims to investigate the influence of expose to a 5% magnesium sulfate solution on the mechanical properties of Portland composite cement concrete (PCC). Sulfate exposure was conducted after the PCC concrete was cured in water for 28 days. Observations and testing were carried out in four stages: before exposure, after 28, 56, and 90 days. The compressive strength of the concrete increased by 8.78% after 56 days of exposure but decreased by 7.2% from the 56-day strength during the 90-day exposure. The modulus of elasticity, Poisson's ratio, tensile strength, and fracture energy were directly proportional to the compressive strength values generated during sulfate exposure. Additionally, the mass of the concrete increased by 0.87% after 56 days of exposure and then decreased to 0.56% during the 90-day exposure.

Abstract

The mixing method for green concrete with a mixture of Ground Granulated Blast Furnace Slag (GGBFS), Fly Ash and artificial coarse aggregate is an important thing that needs special attention to achieve a uniform mixture of materials. Testing the effect of the mixing sequence was carried out to obtain the optimum mixing sequence for the green concrete mixture. The experiment was carried out using 4 different methods, namely a combination of 25% fly ash, 25% GGBFS and 25% artificial coarse aggregate with different mixing sequences for cement material, coarse aggregate, fine aggregate, artificial aggregate as well as water and admixture dosages. Test results based on workability parameters, slump loss, compressive strength, split tensile strength, concrete shrinkage and heat of hydration show that mixing method 4 has 5% higher compressive strength results than other methods, and produces optimum workability and slump loss. Concrete mixed with GGBFS, Fly Ash and artificial coarse aggregate can reduce the heat of hydration by 15%. Artificial coarse aggregate reduces compressive strength by 7%, but has better concrete shrinkage.
