Abstract

In construction projects, inadequate implementation of the Occupational Safety and Health Management System (OHSMS) poses risks to the safety and well-being of workers, resulting in decreased performance and compromised project quality. This study focuses on the Kapas-Glendeng bridge widening project in Bojonegoro Regency, identifying key obstacles such as workforce competence, limited experience, insufficient training, and challenges accessing digital information. Additionally, issues related to worker involvement in regulation-making, understanding of Personal Protective Equipment (PPE), reporting procedures, and documentation of work accidents were observed. To address these challenges, the study recommends strategies such as involving untrained workers in competence-building programs, providing apprenticeships for less experienced personnel, implementing comprehensive training information systems, actively engaging workers in project planning, enforcing OHS monitoring systems, ensuring mandatory PPE usage with penalties for violations, and establishing clear procedures for recording and reporting work accidents. This proactive approach aims to enhance OHS implementation and mitigate risks in construction projects.

Abstract

The construction of the Bahtera Elang Perak Indonesia (BEPI) Office is one of the ongoing projects in Surabaya City consisting of 8 floors with an area of 1,081 m² and a contract value of Rp. 13,908,226,157.00. The Bahtera Elang Perak Indonesia office construction project is planned to last for 43 weeks. In reality, when the piling work is in progress, there are several changes so that there is a need for rescheduling or re-schedulling. The length of implementation time became 54 weeks. The current condition of the progress of the construction of the Bahtera Elang Perak Indonesia Surabaya office is in week 37 at 35.67% while the planned progress is 43.619% so that there is a difference of -7.948%. In order to address this issue, an evaluation of the project's cost and time efficiency during implementation is conducted utilizing the Earned Value Method. This strategy seeks to assess the project's performance in terms of both cost and time. The analysis conducted in week 41 revealed that the performance of the project, in terms of cost, was below expectations with a CPI value of 0.945, indicating that the actual costs exceeded the budgeted costs. Additionally, the CV value of Rp. -381,606.94 further confirmed this negative deviation. In terms of time, the project also experienced delays, as indicated by an SPI value of 0.758, which is less than 1. The SV value of Rp. -2,082,524,745 further highlighted this delay, indicating that the completed work packages were fewer than planned.

Abstract

The Gelora Bung Tomo area currently includes a football stadium, three training fields, a wheel-shoe track, a motorcycle racing circuit, and a multipurpose indoor sports building. With the evolving automotive industry, upgrading the circuit from grade D to grade C is necessary to accommodate more races. This involves extending the 650-meter road race track to 1700 meters, including a pit stop area, audience tribune, paddock, and commercial area. The study evaluates the current facilities of the Gelora Bung Tomo (GBT) area in Surabaya and conducts investment analysis to determine financial viability. The research methodology combines quantitative and qualitative approaches using previously obtained primary and secondary data, then compiles cash flow projections and performs investment analysis using investment valuation methods, namely net present value (NPV), internal rate of return (IRR), benefit cost ratio (BCR), and payback period (PP). Based on the results of the analysis with the Net Present Value (NPV) method, if a positive value of Rp. 13.339.690.346 is obtained, then the investment is acceptable. If the benefit-cost ratio is greater than 1,1849, then the project is accepted, and the PP is 30.98 under the time of the investment of 50 years, but the greater the risk faced, the more the overall investment is worthy of being implemented.

Abstract

Preparatory work in a construction project generally includes the fulfillment of work facilities, field investigations, and licensing, and is typically non-structural. The implementation of the Jakarta Sewerage Development Project Zone 1, Package 2: Construction of Sewers in Area 1-1, which is currently still in the preparatory work stage, is experiencing significant issues. Specifically, the project is facing a very complex licensing process, resulting in minimal work progress. This is due to the project planning phase not adequately considering the timeframe required for obtaining an implementation permit. Therefore, this paper analyzes the project timeline to identify project performance during the preparation period before the main project work implementation stage. In this study, the Critical Path Method (CPM) scheduling method was applied to the project to determine the activities on the critical path, utilizing the Microsoft Project application. The analysis identified that the activities on this critical path include Document Submission Work, Shaft Location C-8.1 Work, 8-span Pipe Jacking Work, Diversion Chamber Work, and Contract Closing. The analysis of the relationship between the licensing process and the critical path of the Master Schedule, as determined by the CPM method, revealed a delay in the start time of Shaft work from the planned June 3, 2024, to June 21, 2024, representing a 17-day delay from the original plan.

Abstract

Project management plays a critical role in ensuring the success of infrastructure projects like road implementations, which are essential for the development of emerging regions such as Baucau City, Timor Leste. Challenges often arise due to discrepancies between planned schedules and actual implementation, exacerbated by logistical constraints and unforeseen changes in project requirements. Effective cost management, exemplified by methods like Earned Value Management (EVM), becomes crucial in maintaining project feasibility and controlling expenditures. The purpose of this study was to analyze the cost of road implementation projects using the Earned Value Analysis Method. The method used in this study is to use the Earned Value Method with a project duration of 18 months, where the importance of the earned value analysis method is very helpful for the owner and project implementer to more easily analyze the performance of the project being carried out so as to provide benefits for the owner and project implementation. The findings revealed a project cost overrun of $205,483.12, attributed to low labor productivity and inadequate management, resulting in extended project timelines and subsequent delays in follow-up activities.

Abstract

With the dominance of top-down development, the aspirations of the community's ideas in every stage of construction development are not perfectly absorbed, resulting in community antipathy towards every government policy. Therefore, to recreate public sympathy, the government released a program to strengthen village governance and development (P3PD) or better known as the village fund program. The AHP (Analytical Hierarchy Process) method is used to analyze the results of the questionnaire so that the weight value of the criteria and sub criteria can be known as the basis for selecting the implementation of construction activities. Based on the results of the analysis, the weight value of the criteria can be found as follows: quality criteria are the main criteria in the selection of construction projects with a weight of 0.235, cost with a weight of 0.203, time with a weight of 0.192, community participation with a weight of 0.144, labor with a weight of 0.117 and administration with a weight of 0.110.
