Abstract

Development in Indonesia is partly on soft soils, for example the opening of transmigration areas and the construction of roads connecting cities on the east coast of Sumatra Island. The two main problems of construction on soft soils are large settlement and low bearing capacity. One of the soil improvement efforts that will be investigated is soil stabilization with cement and chemicals. Observations were only made on the bearing capacity of the soil using a free compressive strength tester. The stabilized soil type is soft clay with dominant mineral content of montmorillonite from P. Rimau, South Sumatra. The levels of cement mixed in the soil were 2, 6, 10 and 15% of dry weight with treatment periods of 1, 3, 7, 14 and 21. The chemicals used to improve cement properties in organic soils are NaOH, KOH and Na2CO3. The results showed an increase in strength both for the addition of cement content and for the addition of the treatment period. The increase in soil strength reached 500% - 1,450%.

Abstract

The movement of pipe in sand and clay are presented, formulated and analyzed using a linear interpolation method within the framework of elastic perfectly plastic Mohr Coulomb criteria and a new two-mechanism- non-associative piecewise linear Drucker Prager formulation. The two mechanisms are found when the variation of shear strength due to mean effective stress is separated from that due to plastic deviatoric strain. The modelling framework is intended to show the deformation and displacement of soil surrounding pipe. Furthermore it also describes the relationship between displacement and the force. Horizontal and vertical displacement are applied into pipe and they are modelled using finite element program, CRISP version 4. Slip element (interface) is attached in the vicinity of pipe to compare the deformation produced in this case with those without interface. Different material properties of cohesive and granular soil taken from laboratory tests are set in the model. All main parameters are recorded from lateral and horizontal loading test, as a part of the Collaborative Project on Soil/Pipe Interaction Mechanisms and Modelling. Application of the approach are presented and discussed with emphasis on identifying and optimizing some of the important factors that control the displacement of soil because of the movement of pipe. Several conclusions are drawn regarding the difficulties encountered in the numerical implementation. Illustrative numerical results for common geotechnical experiments on clay and sand using finite element software demonstrate the stable derivation of the two linear non associative Drucker Prager model.

Abstract

Stability is one of the regular calculation elements in geotechnical engineering. Stability calculations relate to the collapse of a soil mass with large deformation occurring in the collapse plane followed by the collapse of the geotechnical structure. This shows that the analysis of stress-strain behavior at critical state is very important. Soil behavior depends not only on the initial and final stress state but also on the trajectory at which the stress and strain state changes and the previous loading history. The trajectory is different for each type and consolidation state of the soil sample. However, the trajectory will tend towards a unique boundary surface and then along the surface to a single and unique critical state line. This paper aims to describe the critical state line, which is the final destination of the collapse of the loaded soil, and to describe a boundary surface consisting of the Roscoe surface, which is typically traversed by normally consolidated soil samples, and the Hvorslev surface, which is typically traversed by overconsolidated soil samples. A case study was conducted on clay soil samples at U.K. Maranatha Bandung. The shear test conducted was undrained sriaxial consolidated test. The case study shows that the soil sample belongs to normally consolidated clay. The critical state parameters obtained are M and 2.

Abstract

The quality of road construction is highly dependent on the quality of human resources of organizers, managers and also road users considering that the quality of construction is a product of construction activity actors including project owners (owners), contractors as implementers and also consultants both as planners and supervisors; but not to forget the road users. In general, the human resources owned by the perpetrators of activities are actually sufficient and have adequate 'abilities' both in the field of engineering and road construction, this can be seen from the large number of human resources who have attended and graduated from various training and development ranging from courses, training, education, etc. in the field of road engineering. However, the facts show that the quality of the road construction industry is still far from satisfactory as seen from the many premature damages to road construction. A new problem, the ethical problem, is relatively more complicated than the capability problem. The word 'ethics' may be too harsh and harsh, so it would be better to call it a 'culture' of willpower because it concerns not only road operators, but also road users. In general, it appears that all the problems of road construction, utilization and management are inadequate, especially those related to human resources in terms of the ethics of the human resources concerned. For this reason, it is necessary to rethink what “breakthroughs” can be made by institutions responsible for the quality of human resources.

Abstract

The important thing in teaching besides mastering the material to be taught is how well. The two things above are closely related, how to deliver the right material is very dependent on how the style and way of learning of students who listen to it. Learning styles explain individual differences to more effectively learn a concept, based on learning styles there are groups of ES (Extroversion Sensing), IS (Introversion Sensing), EN (Extroversion Intuition), IN (Introversion Intuition). In addition to Learning Styles, there is also the term Learning Ways, which shows the different ways that individuals absorb and understand information optimally. Learning styles are known as Visual, Auditory and Kinesthetic. Research on students of the Civil Engineering Department of U.K. Maranatha class of 2003 shows the tendency of learning styles ES, EN, IS, IN respectively 41.38%, 34.48%, 6.9%, 17.24%, while the majority of learning styles are Visual (68.97%) then Auditory (20.69%) and Kinesthetic (10.34%). This study concludes that most students show the tendency of ES learning style (41.38%) with the characteristics of easy learning with application and realistic. While the way of learning is dominated by Visual shows that students will capture and understand more information through what is seen. Hasil peneltian ini dapat memberikan informasi untuk mengajar Mekanika Rekayasa dengan tepat yaitu melalui simulasi, studi kasus/aplikasi , diskusi kelompok kecil serta memberikan banyak gambar menarik dan warna untuk menjelaskan materi/rumus yang diberikan. Cara mengajar yang cenderung satu arah dan menonjolkan banyak rumus daripada visualisasi yang menarik tampaknya harus ditinggalkan sehingga diharapkan mahasiswa akan menikmati pelajaran Mekanika Rekayasa dan tentunya hal ini akan berdampak pada hasil akhir yang didapat.

Abstract

Currently, the Kobutri bus company operates only 8 units out of 12 units, and the route served is KPAD-Antapani. The level of service is relatively low as passengers are crammed standing like pindang fish. This may be due to the tariff charged to passengers is low so it does not cover the cost of operating the vehicle. Therefore, it is necessary to conduct research to determine the appropriateness of the applicable tariff. Data collection was carried out using a survey method to passengers, drivers, owners and managers to obtain primary and secondary data for the purposes of analyzing Vehicle Operating Costs (BOK), the amount of tariffs and actual real deposits Using the Cost Component Analysis Method, Determination of Tariffs and Deposits, and Net Present Value Analysis, appropriate values were obtained.From the results of the analysis, it was concluded that the tariffs and deposits obtained from the calculation of vehicle operating costs using the actual number of passengers were smaller than the tariffs set by the government. In this case, it means that the company gets enough profit and the amount of the existing tariff is not the main cause of the decline in Kobutri transportation services majoring in KPAD-Antapani.

Abstract

In determining a contractor, project owners are usually interested in choosing the lowest bid, but that is not always true. For this reason, a bid evaluation is needed that can provide a fairly detailed description of the offers of each prospective contractor. Evaluation of bids from contractors is carried out by considering three aspects, namely: administrative aspects, technical aspects and price bidding aspects. These three aspects are evaluated one by one using a bid evaluation system by taking into account the requirements set by the consultant concerned. This case study contains data from the winning contractor, in this case PT Teguh Puncak Lestari and not the lowest bidder. This data includes administrative data, technical data and price bid data that will be used for bid evaluation. The system used in evaluating this bid is a value system, which is by assessing the administrative aspects, technical aspects and price bid aspects. In the value system, all requirements from the administrative aspect must be met first, then for the technical aspect and the price bid aspect are determined by a score. This score determines the winner of the tender. From the bid evaluation results, it turns out that PT Teguh Puncak Lestari has a complete administrative score, technical score = 60.50 and bid price value = 25.38. In evaluating bids, it is necessary to have staff who really master the technical aspects related to the project concerned.

Abstract

The planning of earthquake-resistant building structures in Indonesia is very important considering that most of Indonesia is located in an earthquake area with moderate to high intensity. The latest trend in earthquake-resistant building planning today is performance-based design. The performance-based planning concept is a combination of resistance and service aspects. In this study, six reinforced concrete buildings with moment-bearing frame structural systems with special and medium criteria, ten stories high, consisting of a regular (symmetrical) building and an irregular (symmetrical) building, were designed in accordance with the Earthquake Resistance Planning Procedure for Buildings [SNI 1726, 2002] and the Concrete Structure Calculation Procedure for Buildings [SNI 03-2874, 2002]. The seismic behavior of these structures was evaluated using static nonlinear/pushover analysis and inelastic dynamic time history analysis. The study results show that the pushover analysis yields actual ductility (ua) and seismic reduction factor (R) greater than the design pq and R, so the pushover analysis is rational enough to be used in determining the ductility and R factor of regular reinforced concrete building structures. At the same transition target, the building designed with SRPMK generates less base shear force than the building designed with SRPMM. The results of the performance-based design evaluation show that all the buildings reviewed are included in the Damage Control Performance level so that the building is in a category that in the post-earthquake damage that occurs varies between the Immediate Occupancy and Life Safety performance levels, the risk of casualties is very low, the building structure may be damaged, but does not collapse. While the results of the time history analysis show for all buildings analyzed with the 1940 El Centro, 1992 Flores and 1971 Pacoima Dam earthquakes, the transitions, drifts and plastic joint rotations that occurred have not exceeded the allowable limits, while for the Bucharest earthquake produced transitions and drifts that exceeded the ultimate limit performance, buildings in region 4 produced plastic joint rotations that have not exceeded the allowable limits and buildings in region 6 rotations have exceeded.
