Abstract

In mitigation to minimize the risk of earthquakes, protection is needed to reduce the impacts. Damage caused by earthquakes can be minimized by planning and building earthquake-resistant houses. To get an earthquake-resistant house, by adding earthquake-strengthening components based “Pedoman Teknis Rumah dan Bangunan Gedung Tahan Gempa and SNI 1726-2019”. This research aims to design earthquake-resistant houses concept for an earthquake period of 50 years and analyze the benefit-cost ratio by comparing residential houses designed with earthquake-safe features to conventional residential houses. The concept of earthquake-resistant houses is carried out in conventional type 120 residential houses. The research results that the cost for a conventional residence is IDR 387,223,000 and the cost of an earthquake house concept is IDR. 407,593,000, where there is a cost difference of IDR 20,370,000 or 5% (more expensive). Benefit-cost ratio value for conventional residential houses for the 50-year earthquake scenario is 0.64; 0.71; 0.77; 0.82; and 0.87 where the value of BCR <1, then this residential house is not effective in facing a 50-year earthquake scenario. Benefit-cost ratio for earthquake-safe housing was 1.12; 1.34; 1.58; 1.84; and 2.09. The BCR>1 and the value moves up until the 50th year. So with an additional cost of 5% for earthquake-safe features, this house is considered very effective for the 50-year earthquake period scenario.

Abstract

Construction projects are activities carried out with limited time and costs. In its implementation, the project requires resources, namely materials, wages, tools and decisions on the use of subcontractors. Project implementation always begins with implementation planning. This activity consists of planning work methods, calculating project resource requirements, and determining the schedule for procuring these resources. Every project implementation always has risks in it. This risk can originate from human resources, implementation methods, and work environment conditions. Due to the limited time for implementing construction projects, it is not uncommon for planning project resource requirements to experience calculation errors. This error could be a lack of budget allocated to one of the project resource components. This research was carried out with the aim of obtaining the proportion of each resource, namely materials, wages and tools, which can later be used as a reference in preparing project plans in a short time. This research was conducted on a building construction project that functions as a hotel and villa. The projects reviewed are 2 hotels, 1 villa and 1 resort. The results of this research show that the average proportion of project resource use to the total value is (1) Materials 64.45%, (2) Wages 24.75%, (3) Tools 7.64%, and (4) use of subcontractors 3 .17%. The proportion of use of material resources, equipment, wages and subcontractors is greatly influenced by the type of building construction, material specifications and work contracts.

Abstract

Mount Agung is a type of volcano that is still active and showing signs of eruption. The existence of Mount Agung is located in Rendang District, Karangasem Regency, and is a tourist attraction for the area, which encourages the acceleration of development, so that quite a few people in Rendang District, or indeed, the existing ones, live in residential areas that are included in areas prone to volcanic eruptions. This will, of course, be high-risk because the living conditions are unsafe against the risk of a disaster that could come suddenly. To anticipate the possibility of being affected by volcanic eruptions, research is needed to identify the level of vulnerability to Mount Agung eruptions in residential areas of Rendang District. The research method used is a quantitative descriptive method using a spatial analysis approach with the help of GIS (Geographic Information System) analysis tools and scoring analysis. Based on the results of the analysis, it was found that residential areas in Penempatan, Besakih, and Menanga Villages are not suitable for housing because they have a high level of risk of volcanic eruptions with a total score of 131. Residential areas in Rendang, Nongan, and Pesaban Villages are categorized as suitable for housing because they have a low risk of volcanic eruptions, with a total score of 126. It can be concluded that residential areas in the villages of Penempatan, Besakih, and Menanga have a high risk of being affected by volcanic eruptions. so that in the future it is hoped that it will become a reference for the area when there will be a relocation or when developing built-up land so that the risk of disasters in this area can be anticipated.

Abstract

Cost estimation as a reference for analyzing the budget for the implementation of construction projects is very vulnerable to risks, so analysis is needed to reduce losses that can occur. The aim of study is to discover dominant risks, evaluate risks, define risk mitigation strategies and risks ownership to the cost estimation process at the planning stage. The research uses mix methods beetween qualitative and quantitative and data collection through surveys and interviews. The research respondents used the purposive sampling method. The results of the study showed that the identified risks amounted to 35 (thirty-five) risks and came from 9 (nine) risk sources. Risks that are included in the dominant category are unacceptable risks (unacceptable) as many as 10 risks and undesirable (undesirable) risks as many as 25 risks. The mitigation carried out is to appoint an experienced estimator, improve coordination between teams, ensure the availability and accuracy of data and learn more details of tender documents. The allocation of risk ownership on the contractor side is 33 risks (94.29%), followed by the owner and planning consultant each have 1 risk allocation (2.86%).

Abstract

Bridges are essential infrastructures that serve to connect two regions separated by various geographical conditions. Among the various types of bridges, suspension bridges are commonly used for long-span applications. The main structural components of a suspension bridge consist of the main cables and vertical suspenders. Due to their long spans, suspension bridges are susceptible to differential ground motions at each support, which may arise from varying soil conditions—this phenomenon is referred to as multi-support excitation. In this study, three types of analyses were conducted: static analysis, dynamic analysis under longitudinal seismic excitation, and dynamic analysis under transverse seismic excitation, using MIDAS Civil software. The soil conditions applied in all three analyses were assumed to be stiff soil at the left support and soft soil at the right support. The structural responses observed include internal forces and displacements. The seismic loads were defined using the time history method. The time history records were derived from the conversion of response spectra for the Bukittinggi region, considering both stiff and soft soil conditions. The results indicate that, in both longitudinal and transverse dynamic seismic analyses, the highest internal force values predominantly occurred at the support located in the soft soil area, except for moment values, which reached their maximum at the support in the stiff soil area. The maximum Dynamic Amplification Factor (DAF) in the longitudinal direction of the girder occurred at an element located at 0,25 of the span length on the right side, with a value of 2,621.
