Abstract

Infrastructure development plays a very important role as capital in efforts to stimulate increased economic productivity, both at the national and regional levels, as well as reducing unemployment, alleviating people from poverty and of course improving the standard of living of the community at large. Delays in completing a project are a problem that often arises and can have an impact on the entire work, especially with time delays resulting in increased costs which can be detrimental to many parties. This delay also occurred in the Kapas-Glendeng 8 bridge construction project, Bojonegoro Regency. In anticipation of these delays, it is necessary to accelerate time and costs. In this research the author uses the crashing method with the alternative of increasing working hours. The crashing method is a way of estimating cost variables to determine the maximum and most economical reduction in the duration of an activity that is still possible to reduce. The research results showed that the total time and cost of the project required after crashing was 174 calendar days with a cost under accelerated conditions of Rp. 2,555,189,555.98 with a difference of 6 calendar days from the normal duration of 180 calendar days and a fee under normal conditions of Rp. 2,548,581,990.63.

Abstract

In a construction project, preparation work typically includes tasks related to setting up work facilities, conducting field investigations, obtaining permits, and non-structural activities. The Jakarta Sewerage Development Project Zone 1, Package 2, which involves the construction of sewers in Area 1-1, is currently in the preparation phase and is experiencing challenges due to a complex permit process. This has led to minimal progress as the initial project planning did not consider the time needed to secure the necessary permits for implementation. The author is therefore evaluating the project timeline to gauge performance during the preparation phase before actual construction begins. This study utilizes the Critical Path Method (CPM) scheduling technique in Microsoft Project to pinpoint critical activities. Upon analysis, it was found that the budget plan for Package 2 of the Jakarta Sewerage Development Project (Zone 1) was detailed and included various work descriptions, with a total budget of IDR 862,292,086,196. However, delays have occurred, resulting in a 17-day setback in the project schedule, necessitating work acceleration. To bring the project duration back in line with the original schedule as per the contract, acceleration was required. This was carried out on the Shaft Construction C-8.1, which was initially set to take 80 days but was shortened to 63 days through time acceleration, incurring a cost of IDR 23,279,288.

Abstract

Provision of Sports Prasarana is an attempt to fulfill the basic rights of the public to obtain services in sports activities, as listed in Law of the Republic of Indonesia Number 11 of 2022 concerning Sports 2022. The growing automotive industry is one important sector that significantly contributes to Indonesian economic growth. Based on the Surabaya City for 2021-2026 calls for the creation of an integrated area, with the Gelora Bung Tomo area serving as an international sports center and integrating with the growth of trade and service functions in Surabaya's surrounding areas. The aim of this study is to measure the amount of investment income and revenue limits in an effort to reduce the risks associated with the investment in the circuit. We carry out flow calculations using the Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (BCR), and Payback Period (PP) methods, and then analyze the sensitivity. We reviewed the sensitivity analysis based on several parameters, including commercial rent income and circuit management costs. The development of Tomo's Gelora Circuit is sensitive to a loss of income from the rental of business or commercial premises of 8%, which will affect a decline in profit, resulting in a negative net present value (NPV) and prolonging the rate of return. Additionally, it is sensitive to an increase in management costs by 12%.

Abstract

The Kali Kamoning Watershed in Sampang Regency, spanning 35,421.15 Ha, experiences annual major floods affecting Sampang City. Despite various attempts and budget allocations at different administrative levels, flooding remains a persistent issue. A proposed solution is the implementation of an Ecodrains-based sponge village model for flood control, specifically targeting upstream areas like Karang Penang, Robatal, Kedungdung, Omben, and Sampang sub-districts. The model, cost-effective and easy to construct, utilizes the HEC-HMS software for technical analysis, simulating river capacity and calculating flood reduction. The sponge village model demonstrates a substantial reduction of flooding by 73.14%, equivalent to 326.3 m3/sec. The Q25th flood discharge measures 446.1 m3/sec. Estimated construction costs using the SNI method amount to IDR 917,588,260,000, aiming to control the Q25th flood. This innovative approach offers a promising strategy for mitigating flooding in Sampang City through sustainable watershed management and cost-efficient infrastructure development. Key terms: Watershed, Flood Reduction, Ecodrains, Sponge Village Model, HEC-HMS, Q25th, Construction Costs.

Abstract

The Genengan–Lembeyan road in Magetan Regency serves as a vital transportation route, connecting Magetan and Ponorogo Regencies. As a primary collector road, it facilitates the distribution of goods and community mobility but experiences significant surface deterioration due to high traffic volumes and heavy vehicle loads. This study evaluates the pavement condition using the International Roughness Index (IRI) method, supported by the Roadroid application, a smartphone-based tool for assessing road unevenness. The research identifies an average IRI value of 4.24, which suggests that the overall road condition is moderate to good. However, critical segments, particularly between STA 5+000 and STA 8+660, exhibit moderate to severe damage, including cracks, potholes, and surface deformations, necessitating immediate repair. The estimated repair costs, calculated using the Bina Marga 2024 guidelines, amount to IDR 4,069,031,000. This study emphasizes the effectiveness of the Roadroid application in providing accurate, real-time road condition data, offering a cost-efficient and practical alternative to conventional methods. The findings underline the importance of timely maintenance to prevent further deterioration, enhance road safety, and sustain transportation efficiency. Furthermore, the study advocates for regular evaluations using innovative tools like Roadroid and improved drainage systems to mitigate damage caused by environmental factors. The insights from this research contribute to better infrastructure management in Magetan Regency, demonstrating that integrating modern technology can optimize road maintenance planning and execution while supporting economic growth through reliable transportation networks.

Abstract

In the Kandya House Villa Construction project in Ubud, Bali, there was a delay with a time deviation of -11.97%. This delay has the potential to cause the completion time of the work, which according to the contract is scheduled for 53 weeks, to be exceeded. To evaluate the time and cost performance in this project, the Earned Value method was used. This method utilizes three main indicators, namely Actual Cost of Work Performed (ACWP), Budgeted Cost of Work Performed (BCWP), and Budgeted Cost of Work Scheduled (BCWS). The results of the analysis show that the project time performance has decreased, characterized by a Schedule Variance (SV) value of -Rp 375,265,411.62. This value reflects a significant difference between planned and completed work. In addition, the Schedule Performance Index (SPI) was recorded at 0.772, which means that time efficiency only reached 77.2% of the planned schedule. As a result, the projected completion of work using the Estimate to Schedule (ETS) and Estimate at Schedule (EAS) indicators increased to 421 days or equivalent to 60.090 weeks, far exceeding the contract duration. In terms of cost, the analysis shows suboptimal performance, with a Cost Variance (CV) value of -Rp 48,700,590.06. This indicates that the actual costs incurred were higher than the planned budget for the completed work. In addition, the Cost Performance Index (CPI) value was recorded at 0.963, which means that the efficiency of budget utilization only reached 96.3%.
