TL;DR: In this paper , the impact of soil structure interactions on the strength of a pile foundation was analyzed using the midas GTS NX and midas GEN programs, which required data such as superstructure models, soil factors, pile specifications, and pile bearing capacity.
Abstract: ABSTRACTThe interaction between pile foundation and soil results a bearing capacity that allows the superstructure to be securely maintained. The interaction impact of the soil structure can lead to more accurate analysis, especially on structure's ability to endure seismic forces. Therefore, the pile foundation must be idealized as a multilinear spring support in order to analyze the interaction of the soil structure. The Midas GTS NX and Midas GEN programs were used to examine the impact of soil structure interactions. The program requires data such as superstructure models, soil factors, pile specifications, and pile bearing capacity. The z-direction deformation (-11,112 mm) and axial force (-2207,914 kN) on the C19-3 pile are both greater than in the corner and edge pile sites under gravity load condition. The z-direction deformation (2,909 mm) and the axial force (587,850 kN) on the C2-2 pile are both greater than in the corner and center pile sites under the x-direction static earthquake load condition. The z-direction deformation (2,909 mm) on the C4-6 pile and the axial force (587,850 kN) on the C4-7 pile are both greater than at the edge and center pile sites under the y-direction static earthquake load condition.ABSTRAKInteraksi antara fondasi tiang dengan tanah menghasilkan daya dukung yang dapat mempertahankan kondisi struktur atas dengan aman. Efek interaksi struktur tanah dapat menghasilkan analisis yang lebih akurat terutama pada kapasitas struktur dalam menahan gaya gempa. Oleh karena itu dalam analisis interaksi struktur tanah, fondasi tiang perlu diidealisasikan sebagai tumpuan pegas multilinear. Analisis efek interaksi struktur tanah dilakukan menggunakan program Midas GTS NX dan Midas GEN. Data yang diperlukan seperti permodelan struktur atas, parameter tanah, spesifikasi tiang, dan daya dukung tiang dimasukkan ke dalam program. Pada kondisi pembebanan gravitasi di tiang C19-3, deformasi arah z (-11,112 mm) dan gaya aksial (-2207,914 kN) kedua nilainya lebih besar daripada di lokasi tiang pojok maupun pinggir. Pada kondisi pembebanan gempa statik arah x di tiang C2-2, deformasi arah z (2,909 mm) dan gaya aksial (587,850 kN) kedua nilainya lebih besar daripada di lokasi tiang pojok maupun tengah. Pada kondisi pembebanan gempa statik arah y, deformasi arah z (2,909 mm) di tiang C4-6 dan gaya aksial (587,850 kN) di tiang C4-7 kedua nilainya lebih besar daripada di lokasi tiang pinggir maupun tengah.

The involvement of construction management consultants is expected to provide reliable information to project owners. The use of construction management consultant services is usually only on large-scale projects,. Various problems at the implementation stage of development often occur. One of the problems that often occurs is the delay in construction time which causes a construction project to not be completed according to the scheduled time. The factors include: unorganized project organization, unprofessional human resources. Therefore, it is necessary to review what the role of a construction management consultant is and how to implement that role in preventing construction delays. The purpose of the study was to determine the role of Construction Management Consultants in preventing construction delays. In carrying out the research, a planning scope was developed which included: literature study, preparation of determining the required data, retrieval of primary data directly from the object under study by distributing questionnaires. After that the results of the questionnaire were processed by thePLS method to find out the influence of the role of construction management consultants in preventing construction delays in the construction of multi-storey buildings and their most dominant role.

TL;DR: In this article , the authors compared five designs of gravity retaining walls in two soil conditions that have different consistency of original soil and embankment soil and calculated soil pressure using conservative method with Rankine Theory and the calculation of stability to the failure of the bearing capacity of the soil is calculated based on the Hansenand Vesic equations based on soil characteristics and technical data.
Abstract: Retaining wall is a structure that is built to retain inclined land or on land where its stability is easilydisturbed. Retaining wall structures are used to withstand lateral soil pressures caused by embankment soilor unstable original soil due to topographic conditions. However, it is also common to find cases oflandslides at project sites where retaining walls have been installed. The failure of this retaining wall isgenerally caused by a design that is not in accordance with the soil conditions at th e project site or due toexternal factors that are not considered in the planning process. Therefore, in designing retaining walls,the parameters and properties of the soil, both original soil and embankment soil, are important factors tobe considered. The purpose of this study is to compare 5 designs of gravity retaining walls in 2 soilconditions that have different consistency of original soil and embankment soil. The design of retainingwalls is checked for shear stability, overturning, soil bearing capacity, global failure, and deformation.Calculation of soil pressure is calculated using conservative method with Rankine Theory and thecalculation of stability to the failure of the bearing capacity of the soil is calculated based on the Hansenand Vesic equations based on soil characteristics and technical data (c and ?). Analysis of shear stability,overturning, and bearing capacity of retaining walls was carried out using conventional method , whilestability calculations against global failure and deformation were carried out u sing the finite elementmethod-based program using CPT data and SPT value on project located in Bukit Asam area, Palembang.and Buleleng Regency, Bali.

TL;DR: In this article , the authors used the Relative Importance Index (RII) method to determine the ranking and the factors causing the remaining material in project X. The method used in collecting data was by distributing questionnaires, direct field observations, and interviewing construction workers.
Abstract: Waste material is material that is not used in processing or application. Waste material is a major concern in current construction projects, because every construction project will certainly cause material waste. The purpose of this study was to determine the ranking and the factors causing the remaining material in project X. The method used in collecting data was by distributing questionnaires, direct field observations, and interviewing construction workers. The research data obtained are the Budget Plan (RAB), the Implementation Budget Plan (RAP). The analysis was carried out by processing primary data in the form of a questionnaire by applying validity and reliability tests, and continued by using the Relative Importance Index (RII) method so that a ranking of the factors causing the material waste was obtained, while from the RAB and RAP data the waste material was ranked based on cost. From the calculation results, it is obtained that the largest waste material is Concrete Steel D-10 mm X 12 m of 15.74% of the total waste value, and the most influential factor in causing waste is the residue factor with indicators of material cutting residue that is no longer used, with an RII value of 0.8667. From the results of the field survey, it was found that one way to minimize the occurrence of waste material is to collect material in different shelters according to the material, so that it can be easily used if needed. Abstrak Waste material adalah material yang tidak terpakai dalam pengerjaan atau penerapan. Waste material merupakan perhatian utama di dalam proyek konstruksi sekarang, karena setiap proyek konstruksi tentu akan menimbulkan sisa material. Tujuan dari penelitian ini ialah untuk mengetahui peringkat dan faktor-faktor penyebab sisa material pada proyek X. Metode yang digunakan dalam pengumpulan data ialah dengan cara pembagian kuesioner, observasi langsung dilapangan, dan wawancara para pelaku konstruksi. Data penelitian yang diperoleh ialah Rencana Anggaran Biaya (RAB), Rencana Anggaran Pelaksanaan (RAP). Analisis dilaksanakan dengan mengolah data primer berbentuk angket dengan mengaplikasikan uji validitas dan uji reliabilitas, dan dilanjutkan dengan menggunakan metode Relative Importance Index (RII) sehingga didapatkan peringkat faktor penyebab waste material, sedangkan dari data RAB dan RAP didapatkan peringkat waste material berdasarkan biaya. Dari hasil perhitungan, didapatkan waste material terbesar adalah Besi Beton D-10 mm X 12 m sebesar 15.74% dari total nilai waste, dan faktor paling berpengaruh dalam menyebabkan waste ialah faktor residu dengan indikator sisa pemotongan material yang tidak terpakai lagi, dengan nilai RII sebesar 0.8667. Dari hasil survei lapangan didapat salah satu cara meminimalisir terjadinya waste material ialah mengumpulkan material pada tempat penampungan yang dibedakan sesuai dengan materialnya, sehingga dapat dan mudah digunakan jika diperlukan.

TL;DR: In this paper , the relative importance of communication management integration factors in construction projects based on the Relative Importance Index (RII) analysis was determined by distributing questionnaires to project managers from large and medium qualified contractors in Banda Aceh City.
Abstract: Ineffective communication can lead to work delays, quality discrepancies, and cost overruns. Thus, effective communication is needed to support the success of construction projects. Poor communication is one of the causes of project failure with a percentage of 56%. On the other hand, effective communication is considered to increase the suitability of the plan in project completion by up to 17%. Communication is a core competency that must be implemented properly in order to achieve the same strategy, goals, and actions. The purpose of this study was to determine the relative importance of communication management integration factors in construction projects based on the Relative Importance Index (RII) analysis. RII analysis will sort the importance of factors based on the highest to lowest RII values. Data was collected by distributing questionnaires to project managers from large and medium qualified contractors in Banda Aceh City. The results of data analysis obtained 3 important factors to integrate communication management in construction projects, i.e.: competence (0.938); management (0.922); and strategy (0.911). If viewed from the sub-factors, there was 5 important sub-factors to integrate communication management in construction projects, i.e.: skill (0.958); attitude (0.950); task clarity (0.942); stakeholder involvement (0.933); and knowledge (0.925). Abstrak Komunikasi yang tidak efektif dapat menyebabkan keterlambatan pekerjaan, ketidaksesuaian mutu, dan kelebihan biaya. Sehingga, diperlukan komunikasi yang efektif sebagai penunjang keberhasilan proyek konstruksi. Komunikasi yang buruk menjadi salah satu penyebab kegagalan proyek dengan persentase sebesar 56%. Sebaliknya, komunikasi yang efektif dinilai dapat meningkatkan kesesuaian rencana dalam penyelesaian proyek hingga 17%. Komunikasi menjadi kompetensi inti yang harus dilaksanakan dengan baik agar dapat mencapai strategi, tujuan, dan tindakan yang sama. Tujuan dari penelitian ini adalah mengetahui kepentingan relatif faktor -faktor integrasi manajemen komunikasi pada proyek konstruksi berdasarkan analisis Relative Importance Index (RII).
