Thu, 24 Oct 2024 10:59:48 +0000

Road infrastructure development is an important factor in supporting economic growth and community mobility in urban areas. However, road construction in urban areas is often faced with various challenges, such as limited space, population density and the dynamics of community activities. This requires effective and efficient construction management to ensure the smoothness and success of the project. The aim of this research is to find out how cost calculations are carried out using AHSP and also to find out how to carry out and time schedule construction work for inner city lane roads. The method for implementing the construction of lane roads in the city is in the form of asphalting roads with a length of 3.06 KM and a duration of 90 days. The budget plan for building a 3.6 KM inner-city toll road is IDR. 10,428,920,000.

Efektivitas Metode Zero One Dalam Manajemen Resiko Pekerjaan Konstruksi Gedung Berlantai (Studi Kasus Gedung Kuliah Fakultas Kehutanan Dan Ilmu Lingkungan Universitas Halu Oleo Kendari)

Fri, 25 Oct 2024 01:08:01 +0000

This study aims to analyze the visibility of the Zero-One method in the construction of the Faculty of Forestry and Environmental Sciences Building, Halu Oleo Kendari University, Southeast Sulawesi. The results of the analysis showed that a weak control system was the main cause of delays and additional costs in this project. This variable has the highest weight, reaching an average of 90.38, in line with secondary data in the form of monthly reports from the project which show that there is a delay of 1-2 weeks of working days in the process of vertical formwork on floor plate work 2-3, this has a major impact on project time and cost. Corrective measures that can be suggested include optimization of staff performance through material training and risk management, as well as better strategies to address weak systems and avoid delays. The results of this analysis also highlight other risks such as errors in budget planning, material expenditure, and inefficient use of materials. This research was conducted by collecting data from 9 respondents involved in the project. In parallel with the secondary findings of the monthly report of the project, it was identified that there were delays in certain construction processes. Addressing efforts include increasing working hours and manpower to catch up with delays and minimize the addition of inefficient costs. The study provides valuable insights for improving risk management and efficiency in construction projects, focusing on cost and time control systems.

Penggunaan Standar Metode Work Breakdown Structure (WBS) Pada Proyek Pembangunan Gudang BPBD dan Rumah Jabatan Dandim

Fri, 25 Oct 2024 01:52:03 +0000

In today's modern era, the construction of buildings stands as a crucial element in the development of infrastructure. Among the various methods utilized for managing such construction projects, the Work Breakdown Structure (WBS) has emerged as an effective tool. WBS serves as a project management technique, breaking down complex tasks into smaller, manageable components, thereby facilitating efficient planning, execution, and monitoring throughout the project lifecycle.This research employs the Earned Value Method (EVM) approach, chosen for its adeptness in quantifying project cost and time performance. By integrating three key dimensions - scope, schedule, and budget - EVM offers a comprehensive framework for evaluating project performance.The findings of this study reveal subpar cost and time performance in the construction of the BPBD Warehouse and Military District Commander's office building. Conversely, the construction of the Veterans Building demonstrates stable performance in both cost and time aspects.The observed impact of implementing WBS standards, particularly in the construction of the Veterans Building, proves instrumental in enhancing project control. The detailed breakdown of work items and the clearer identification of required resources streamline the planning of Purchasing Orders (PO), thereby facilitating cost management efforts.

Utilization of concrete waste as an additional material for making concrete. And this research also adds chemical additives to the concrete mix using recycled coarse aggregate which is expected to increase the strength of the concrete. This research aims to determine the effect of adding concrete waste on the compressive strength of concrete due to variations in adding additives (Concrete Mix). and Knowing the comparison results of each substitute mixture of pure coarse aggregate with recycled coarse aggregate added with additives (Concrete Mix). This research method uses an experimental research method by comparing 4 (four) variations of the mixture to determine the compressive strength of concrete with a design compressive strength of 25 MPa. The results of the research show that each variation with a cylindrical specimen of 300mm x 150mm with a soaking age of 28 days, variations normal concrete with an average compressive strength of 25.38 MPa, a variation of 25% waste concrete with an average compressive strength of 21.89 MPa, a variation of waste concrete + 400ml mixed concrete with an average compressive strength of 25.48 MPa and a variation of waste concrete + mixed concrete 600ml with an average compressive strength of 28.31 MPa. So it can be concluded that the use of 25% concrete waste does not meet the planned compressive strength and cannot be used in construction, whereas by adding 400ml and 600ml mixed concrete additives, the maximum compressive strength is obtained and is suitable for use in construction.

The aim of the research is to find out or predict how much a project will cost during implementation and to find out the effectiveness of project control using the Earned Value Method. To overcome existing problems, an Earned Value method is used. There are two parameters or indicators used for analysis, namely BCWS, BCWP. Delay deviations can be identified by looking at the Schedule Variance (SV). This method can also be used to determine the efficiency of resource use in the form of the schedule performance index (SPI). The project implementation time aspect has a negative value up to the 12 th week of (SV) -Rp. 44,776,771.84 or schedule performance index (SPI) = 0.82 < 1. The calculation results are obtained from an effectiveness value of 0.85 for controlling project time using the Method Earned Value. In other words, the results of an effectiveness value that is smaller than 1 (one) can be said to be that the Time Performance for the Implementation of the Concrete Pavement Road Work Project in North Kolaka Regency is less effective. From the results of the time performance study using the Earned Value Method, it can be concluded that the Time Performance for the Implementation of the Concrete Pavement Road Work Project in North Kolaka Regency experienced a delay from the initial plan. It is clear that in weeks 1 to 12 the project performance was delayed from the planned schedule
