Abstract

Sepakat Street, Payung Sekaki District, had puddles on the road surface even though it already has drainage channels on the right and left of the drain with a depth of 0.4 m and a width of 0.6 m. The purpose of this research is to evaluate the planning to improve the condition of the existing drainage channels so that they can drain water. The method used is the Gumbel distribution method to calculate the frequency of rainfall, SNI 03-3424-1994 to calculate rainfall intensity, and the Manning method to calculate flow velocity. Then the results of evaluation calculations on the drainage channel on the road agreed, Payung Sekaki sub-district, Pekanbaru City with dimensions of 0.6 meters wide and 0.4 meters high, obtained that the discharge of the existing channel that can accommodate water on the right is 0.0621 m³/s, and on the left is 0.071 m³/sec, and the total discharge from the discharge and rainfall on the right is 1.20401 m³/sec, and the left is 1.20411 m³/sec. Payung Sekaki, Pekanbaru City, the cause is that the drainage cannot accommodate the existing water discharge so there is a puddle on the road in the Sekaki Payakumbuh sub-district, Pekanbaru City, and after being re-planned according to the existing discharge, the dimensions have been planned for the right and left channels with a width of 0.6 meters and depth of 1.05 meters.

Abstract

One of the building constructions on the hillside in Kebumen Regency requires the implementation of a cut and fill process on the natural slope. The excavation work on the 7-meter-deep slope of cohesive soil has been reinforced with a secant pile type retaining wall. However, during the excavation process, the secant pile experienced a displacement of 1.1 meters. Therefore, it is necessary to evaluate the causes of the displacement of the retaining wall. The finite element analysis software, Plaxis, is used to analyze and evaluate based on displacement values and safety factors. Additionally, the Geo5 software is used to design the depth of secant pile retaining walls using the Rankine analysis method. The evaluation of the excavation construction work resulted in a safety factor of 1.3984. This value is still below the value required by SNI 8460:2017. Based on the analysis with the software, it was found that the secant pile diameter of 60 cm could still cause a displacement of 1.1 meters, even though the safety factor remained stable. The displacement of the retaining wall occurred because the excavation process resulted in the active earth pressure being greater than the passive earth pressure. After optimizing the design, the results show that increasing the secant pile diameter can reduce the displacement and improve the safety factor to meet the requirements of SNI 8460:2018, which is ≥ 1.5. The effective diameter obtained in the optimization is 80 cm, which can reduce the displacement to 0.3 meters.

Abstract

The increasing development of construction projects has led to an increase of work accidents and insurance claims. This must be followed up with the implementation of a construction safety management system. This action is expected to reduce the number of accidents and illnesses due to work. The purpose of the study is to analyze the value level of implementation of construction safety management system and the factor that causing the discrepancy between the requirements and the implementation. This study uses a qualitative research method with a descriptive format. The results showed that the implementation rate of the Construction Safety Management System was 88.37% with the category of "Satisfactory Implementation". The factor that causing the discrepancy are the contractor leader rarely goes to the field to provide briefings related to occupational safety and health because it has been carried out by the project occupational safety and health management team, the implementation of the construction safety management system is good but there are still some differences because the project being worked on is a building construction project, the composition of the Occupational Safety and Health Management Team in the project is adjusted to the needs of the project so that emergency response officers and first aid officers in accidents are not provided in the field.

Abstract

Construction developments in Bali have experienced great progress in recent years, especially in the construction of hotels, resorts and villas. This attracts the interest of many investors to invest in building villas in Bali. An important factor that determines project success is the planning of human resources who are directly involved in project work, especially foremen. One of the projects experiencing delays is the Pasraman Bhagawan Villa Renovation Project. This delay is caused by a focus on the quality of work so that it goes according to plan. Therefore, this study aims to analyze the influence of foreman performance on work quality and the factors that influence it. This research uses data collection methods by distributing questionnaires and multiple linear regression analysis. Based on the analysis results, the R-Square value obtained was 0.949, which means that the foreman's performance influenced 94.9% of the quality of the Pasraman Bhagawan Villa Renovation Project in Jimbaran. Management factors are the most dominant factors influencing project quality with a t count of 4.114. More efficient management of time, resources and budget will help avoid delays and ensure project quality is maintained.

Abstract

One of the most important elements influencing a building project's success is its implementation cost. Issues including ineffective material utilization, inept resources, and improper work method selection frequently arise during project execution. These problems may cause projects to be executed with significant time and expense overruns. Project cost control can be used to lessen these issues. Value engineering analysis is the research methodology employed. Value engineering is used to maximize project budgets by locating and removing wasteful spending. Optimizing building projects in terms of time, money, technology, and creativity is the goal of this study. Price surveys serve as the major means of gathering data for the descriptive quantitative research design. Project managers and material suppliers are among the respondents. The Unit Price Analysis (AHSP) and the Budget Plan (RAB) are two examples of secondary data that were employed. The best alternative design and the least expensive alternative design are the two categories into which alternative designs are divided based on the analysis results. The cheapest option's cost optimization is 9.95%, or Rp1,336,499,405, of the initial design cost, whereas the best option's is 9.14%, or Rp1,222,120,406..

Abstract

As the height of a building structure increases, the building becomes more vulnerable to responding to lateral loads, which is why a dual-system approach is used to resist the lateral forces that occur in the structure. The use of moment-resisting frame systems (MRF) and dual systems differs particularly in terms of earthquake loads. Based on these conditions, an analysis was performed to compare the effects of loading on a frame system versus a dual system in the structural design of the RSU BaliMed Negara building. In the modeling process, two models were created: Structure 1 represents the existing condition, and Structure 2 incorporates the addition of shear walls. The analysis results show that the 100% mass participation value for Structure 1 is achieved at mode 34, whereas for Structure 2, it decreases to mode 15. The natural period of vibration is also influenced by the structural loading, with the addition of shear walls resulting in a shorter natural vibration period for Structure 2 compared to Structure 1. The base shear forces for Structure 1 are Vd in the X and Y directions at 4,856.70 and 4,856.41, respectively, and Vs in the X and Y directions at 4,635.12. For Structure 2, the values are Vd in the X and Y directions at 4,745.47 and 5,745.43, and Vs in the X and Y directions at 5,508.07. The displacement values for Structures 1 and 2 indicate that the displacement in Structure 2 is smaller.

Abstract

Bandar Kedung Mulyo District is an area at risk of groundwater pollution due to agricultural activities involving pesticide use and improper disposal of domestic waste. Preventive measures are necessary to protect groundwater from contaminants. One approach is to assess groundwater vulnerability using the SVV Method. This research aims to evaluate the SVV index as an assessment of groundwater vulnerability derived from parameters such as the thickness of the unsaturated zone, percolation value, and the type of material in the saturated zone. The research results indicate variations in groundwater vulnerability levels, with SVV index values ranging from 11.55 to 47.89 over the five-month study period. There are three classifications of groundwater vulnerability levels: medium (35-65) and high (24-35) with an area percentage of 9 – 10% each. Very high vulnerability (≤ 24) dominates with a percentage of 81 – 82% of the area. The percentage of areas with very high vulnerability decreased, while areas with medium and high vulnerability increased each month. This is due to the decreasing depth of groundwater each month.

Abstract

Soft soil with low bearing capacity presents challenges for infrastructure projects like the Kayu Agung–Palembang–Betung Toll Road. This study aims to identify the most efficient soil improvement method using the Value engineering (VE) approach and simulate associated risks. Using a descriptive quantitative method, data were collected through field observations, expert questionnaires, and project documents. Three methods were evaluated: preloading without vertical drains, with vertical drains, and vacuum preloading. Risk simulation was conducted using the Monte Carlo method with Crystal Ball software. Results show that preloading without vertical drains is the most cost-efficient but carries higher technical risks. Preloading with vertical drains offers a good balance between cost and stability, while vacuum preloading ensures optimal stability with higher costs.

Abstract

Structural damage often occurs in buildings due to earthquake loads. Irregular buildings have a greater risk of damage due to earthquakes than regular buildings. Because the probability of an earthquake occurring in a structure cannot be predicted, an analysis is needed that can describe the vulnerability or fragility due to earthquakes. The purpose of this study was to determine the performance of irregular buildings and the probability of building damage based on seismic fragility. The method used to compile the seismic fragility curve is HAZUS, while the structural performance is obtained from the pushover analysis. Hazus is a method for estimating losses due to disasters, while the pushover analysis is in the form of a push-load application on the structure. Based on the results of the analysis, the structural performance point was obtained with a base shear force and displacement in the x direction of 4194.424 kN and 0.145 m, while in the y direction it was 4187.2016 kN and 0.152 m. The performance level of the building structure based on the analysis results is stated in the Damage Control (DC) condition according to ATC-40 and Life Safety (LS) according to FEMA 440. Based on the fragility curve, the probability of ultimate damage and yield conditions in moderate criteria and the probability of damage in the x and y directions of the building is 100%. The results of this study provide important information about the condition of irregular building structures during an earthquake so that it can be used for structural evaluation and mitigation during an earthquake.
