Abstract

This study investigates the optimal design of bridge foundations incorporating ground improvement techniques in challenging soil conditions, employing a case study methodology. Bridge foundations primarily serve to transfer forces applied by the bridge to the underlying soil, and ground improvement techniques enhance soil properties, particularly in complex environments. Challenging soil conditions pose substantial difficulties in designing and constructing bridge foundations, requiring engineers to employ specific methodologies to ensure stability and long-term resilience. These solutions are crucial in areas with weak or unstable soil incapable of supporting large structures like bridges. This study aims to conduct a thorough comparative analysis to evaluate the suitability of Controlled Modulus Columns (CMC) for a roadway project in north-central Java, where soil conditions present significant challenges. By collecting and analyzing secondary data from various sources, including literature, case studies, and empirical research, the study assesses ground improvement techniques' effectiveness, efficiency, and performance in similar soil and geotechnical conditions. The objective is to determine whether CMCs are the most beneficial approach for enhancing the stability and performance of the highway or if alternative methods, which require rapid installation and high load-bearing capacity while minimizing soil disruption, might be more appropriate. The study highlights that Deep Soil Mixing (DSM) offers advantages comparable to CMCs and has proven effective in different soil conditions. This research aims to provide valuable insights into selecting optimal ground improvement techniques for bridge foundations in challenging soil conditions, ensuring stability and performance while addressing project-specific requirements.

Abstract

The increasing on air transportation passengers and the development of the remote area are factors that accelerate the needed develop of runway pavements. The research aims to find out how to design flexible pavement for runway with two methods, that is CBR (California Bearing Ratio) method and FAA (Federal Administration Aviation) method. Thick of pavement evaluated with PCN-ACN (pavement classification number) method. The designs included a range of subgrade conditions, as well as commercial aircraft and analyzed optimal budget. Case study in the research is Andi Jemma Airport, South Sulawesi. Based on analysis result from the two methods obtained the thick of pavement with CBR method is 21 inch with PCN 27,9 F/C/X/T, thick of pavement with FAA graphic method is 17,5 inch with PCN F/C/X/T and from software FAARFIELD the thick of pavement is 16 inch with PCN 16,9 F/C/X/T. The cost required for thick of pavement analyzed by CBR method is IDR 6.415.252.926, with FAA graphic method is IDR 5.897.401.963 and with the FAA software FAARFIELD is IDR 5.675.465.836. These results indicate that the models obtained for FAA (software) can be used to design the pavement, where as it optimal budget.

Abstract

Transportation is used to facilitate people to do daily activities, and options of transportation mode have an important role in relation to the types of modes and available infrastructures. This study aims to determine what factors influence options of public transportation modes and find out what transportation modes chosen by people who live near Bekasi to Soekarno Hatta Airport by choosing train or bus. The data used in this study are primary data obtained from survey results in the form of questionnaires with the stated preference method by providing several different scenarios. With the influence of variable cost X1, X2 travel time and X3 headway. Furthermore, the secondary data obtained is calculated using the linear regression method and the differences between the utility of the airport train and the bus are used to calculate the probability of the options. The results of the linear regression obtained by the difference in mode selection utilities that is . The conclusion is that the differences in cost, travel time and headway affects the options of transportation modes. Factors that influence the option of public transportation modes are travel time, where the certainty of arrival time to the airport is very important. And the most preferred transportation mode from Bekasi City to Soekarno Hatta Airport is Bus. Where the probability of using bus is greater than airport train.

Abstract

The 2018 Palu-Sigi-Donggala earthquakes in Center Celebes have caused significant damage to many residential houses due to varying degrees of soil liquefaction over a very wide extent of urban areas unseen in past destructive earthquakes. While soil liquefaction occurred in Palu and Sigi, thus providing researchers with wide range of characterize soil and site response to large-scale earthquake shaking. One of important learn issues is prediction of liquefaction. Prediction of liquefaction is also a complex problem as it depends on many different physical factors, and the relations between these factors are highly non-linear and complex. Most of these approaches are based on classical statistical approaches and neural networks. In this paper a new approach which is based on classification data mining (DM) is proposed. The proposed approach is based on historical data from the field and sciences portal. The proposed algorithm is also compared with several other DM algorithms based on rminer. It is shown that the proposed algorithm is very effective and accurate in prediction of liquefaction.

Abstract

Majalengka-Rajagaluh road is a road located in several sub-districts which is a link to the city and also one of the connecting roads to Cirebon City. This design planning starts in Cigasong sub-district and continues to Rajagaluh sub-district with the length of Majalengka-Rajagaluh road is 5.3 kilometers. The geometric design results are visualized in the form of drawings using AutoCAD 2D. The design speed (Vd) was set at 60 km/h with a horizontal curve radius of 358 m, a maximum slope of 4%, and an elevation (e max) of 8%. Based on these design criteria, a spiral curve with a circular curve length (Lc) of 74.996 m was obtained. Furthermore, the results of the vertical alignment calculation of the length (L) of one type of convex curve in PPV were also calculated.
