Soil stabilization by adding new materials is one of the alternatives to soil repair that can improve the properties of the soil, namely by mixing new materials and soil that is then compacted. Waste left over limestone hill mining,among others in the form of materials with various sizes of granules. This study aims to review the effect of the addition of limestone hill mining waste material on the density and value of the California Bearing Ratio (CBR) of clay soil. Tests conducted only on a laboratory scale with variations in the increase in limestone hill mining waste levels are 0%, 5%, 10%, and 15% to the total weight of the mixture. Laboratory CBR testing is performed under optimum water content conditions. The results showed that the stabilization of soft soils using limestone hill mining waste, can increase the density and value of soil CBR. The most optimal level of use of limestone hill mining waste and which provides the highest CBR value is for the addition of 5%of limestone hill mining waste with a CBR value of 26.5%.

Padang City, the most populated city in West Sumatra, is considered to have one of the world’s highest tsunami risks due to its high and close offshore thrust-fault seismic hazard, its flat terrain, and its dense population, which is mostly distributed along the coast. Current preparation for a tsunami in Padang focuses on developing early warning systems, planning evacuation routes, conducting evacuation drills, and educating the public about its tsunami risk. These are necessary, but insufficient, steps. The natural warning in Padang—strong earthquake shaking that lasts over a minute—will be the first and best indicator that a tsunami is likely to strike. It is estimated that even if evacuation begins immediately after the earthquake shaking stops, more than 100,000 inhabitants of Padang will be unable to reach high ground in less than 30 minutes—the expected time between the end of the earthquake shaking and the arrival of the tsunami wave at the shore. Based on Evaluation of Tsunami Evacuation Infrastructure for Padang, West Sumatra, Indonesia (Veronica, et.al: 2011) concluded, based upon extensive fieldwork, that Padang’s existing tsunami evacuation capacity is grossly inadequate, and that tsunami evacuation structures are essential to protect the people of Padang. To maximize their impact and effectiveness, those tsunami evacuation structures should be locally-appropriate, feasible to build and maintain, and easy to replicate. The M7.6 earthquake that struck Padang on September 30, 2009 confirmed this critical need for tsunami evacuation infrastructure. Although the earthquake did not generate a tsunami, it did cause the collapse of many buildings that had previously been identified as satisfactory evacuation structures. The earthquake also triggered massive traffic jams, stranding people in harm’s way and demonstrating why Padang needs structures that enable more people to evacuate-in-place. Finally, it needs to design new structures to accommodate people to evacuate immediately in place. Pedestrian Overpasses Bridge for Vertical Evacuation from Tsunami (POBET) will work effectively for evacuees who get traffic jam during the tsunami inundated elapsed critical hours. The most reason for POBET need to be design is a prototype for the government to combine pedestrian overpasses bridge with vertical evacuation from tsunami. These evacuation infrastructures consider about less for land use, easy to reach, compatible for any infrastructure purposes. Rely on budget and planning, POBET would design with a smallest amount budget and effortless construction process. It can be replicate by the local government to build in any place in Padang City.

In general, the seismic design provisions around the world present different criteria for local soil conditions depending on soil and rock properties to determine the design spectra representing seismic design. On the other hand, site-specific analysis results not only show the main characteristics of soil-rock profiles but also local soil characteristics where detailed studies are needed to review the earth response to earthquakes. In this study conducted Site Specific Response Analysis (SSRA) is to analyze the earthquake wave propagation from the bedrock to the surface layer. The data needed are ground stratification data and shear wave velocity parameters obtained from empirical correlation to N-SPT test drilling data. In addition, the required data is ground motion synthetic at baserocks used for the earthquake wave propagation obtained by Probabilistic Seismic Hazard Analysis (PSHA) 3-dimensional earthquake source referring from the results of previous research. SSRA is based on the theory of single-dimensional wave propagation in time domain using NERA (Non-linear Earthquake Response Analysis) program. Various inputs of earthquake movement are taken by considering suitable for Padang area. The results of this analysis are shown in the form of historical time acceleration graph and peak acceleration from each bore point location which is then processed to obtain amplification and response spectra design factors for the re-quake period of 475 years and 2475 years.

Suatu proyek dikatakan sukses apabila minimal memenuhi empat faktor, antara lain adalah proyek berjalan sesuai jadwal kontrak, mendapatkan keuntungan karena pengeluaran sesuai dengan yang direncanakan, masalah yang terjadi dalam proyek kecil, dan tidak terjadi kecelakaan kerja. Jika teknis yang digunakan kurang baik maka akan berdampak buruk pada kinerja proyek dan dapat menimbulkan kerugian dari segi biaya, mutu, dan waktu. Salah satu kerugian yang ditimbulkan pada pelaksanaan proyek konstruksi disebabkan oleh karena adanya pengerjaan ulang (rework). Tujuan penelitian ini adalah untuk mengetahui faktor-faktor yang menjadi penyebab rework dan faktor dominan apa saja yang menjadi penyebab rework pada pelaksanaan proyek gedung di Kota Padang tahun 2019. Penelitian ini menggunakan instrumen kuesioner yang melibatkan 22 orang responden, terdiri dari 11 perusaaan kontraktor dan masing-masing perusahaan terdapat 2 orang responden yaitu project manager dan site manager. Uji yang dilakukan meliputi uji validitas, reabilitas, korelasi Pearson Product Moment dan analisis deskriptif berdasarkan nilai mean dengan bantuan program Statistical Package for Social Science (SPSS) for Windows version 24.0. Penelitian ini mengidentifikasi 5 faktor penyebab terjadinya rework: faktor manajerial, faktor metoda pelaksanaan konstruksi, faktor material, faktor sumberdaya manusia dan faktor site conditions. Hasil penelitian menunjukkan bahwa faktor paling dominan penyebab rework adalah faktor manajerial, pada sub faktor kurangnya kerja sama tim (teamwork) sehingga hasil konstruksi tidak sesuai dengan kontrak (X1.4) dengan nilai mean 4.32 dan persentase sebesar 86.64 %.

Project construction has complexity conflict (clash). Clash can cause work delays, design changes, additional material, cost overruns, reduced quality, and project delays. Clash construction design can be detected with Autodesk Revit and Autodesk Naviswork manage software which are part of building information modeling (BIM) software. This research found the clash detection Project of X, caused this project's potential clash to be very large because each component is designed by a different team, so when detail engineering design (DED) it intersects with each other component. This study aims to find clash detection (hard clash and soft clash) for structural, architectural mechanical, electrical, and plumbing (MEP) components and provide solutions by repairing the clash. Hard clash found 184 clash points consisting of: clash between structures and architecture with 9 points, structures and MEP with 59 points, architecture and architecture with 16 points, architecture and MEP with 11 points, and MEP and MEP with 89 points. Soft clash found 96 points consisting of: clash between structures and architecture with 52 points, structures and MEP with 1 point, architecture and architecture with 18 points, architecture and MEP with 3 points, and MEP and MEP with 22 points. The solution to the clash found is to change, remove, and add to the components that occur clash using Autodesk Revit, to get zero clash so that this project planning is free clash.

The building performance is an innovative approach that discusses planning, design, construction methods, and the users of the building. To ensure the building functions as intended, maintenance and care are essential. An analysis of user satisfaction regarding building performance reflects users' needs and expectations. Politeknik Negeri Padang, a vocational higher education institution established for 37 years, warrants a user satisfaction analysis of its facilities to maintain comfort in its activities. This research was conducted through a questionnaire survey with 700 respondents, including staff, educators, and students. The analysis using the Suitability Level approach identified three priority indicators for improving building performance: information technology facilities, the condition of public facilities like restrooms, parking, and pantries, and the cleanliness of public toilets. Meanwhile, the Importance and Performance Analysis (IPA) highlighted four key areas for performance enhancement: availability of trash bins and cleanliness of the environment, public facilities such as pantries, toilets, and parking areas, room temperature issues, and information technology facilities like internet connectivity.
