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

Along with the very rapid development of infrastructure and construction in Indonesia in the era of globalization, the Indonesian government has carried out various large-scale projects to achieve the increasingly complex expectations of society. This will trigger the growth of the construction industry in Indonesia and become one of the main goals in the framework of national development. An infrastructure development project is an activity carried out with limited time and resources to achieve a specified final result. One of the construction projects currently being developed is Road Works. The Earned Value method can be used to determine cost performance and implementation time during the project and the indicators used for analysis include: BCWP (Budget Cost of Work Performance), BCWS (Budget Cost of Work Schedule), ACWP (Actual Cost of Work Performance), SV (Schedule Variance), CV (Cost Variance), SPI (Schedule Performance Index), CPI (Cost Performance Index), EAC (Estimated At Complete) and ET (Estimated To Complete) and TE (Time Estimate). Conclusions from this research is to determine the estimated costs and time for project completion. In the data analysis in the 9th week, the project schedule performance (CPI) was 1.14, greater than 1, while (SPI) was 0.587, less than 1. The results of the calculation of projected costs for the remaining work (ETC) were IDR. 1,586,686,537.62 and total project costs (EAC) of Rp. 2,509,041,243.08.

Abstract

Project completion delays have adverse consequences on a contractor's credibility and result in additional penalty costs, reducing potential profits. To mitigate these issues and optimize project outcomes, refining activity schedules and budgets is crucial. The Earned Value Method proves effective in monitoring and controlling project activities. In the case of the Kediri airport access road construction project, weeks 1 to 6 revealed a negative Cost Variance (CV), indicating higher-than-planned costs, while weeks 7 to 8 showed a positive CV, suggesting costs were lower than anticipated. Schedule Variance (SV) for the 1st week was unfavorable, indicating a delay, and SV>1 from weeks 2 to 8 signaled a project delay. The Estimate to Complete (ETC) is IDR 17,470,510,292.77, and the Estimate at Complete (EAC) is IDR 32,509,153,464.05. The Time Estimate (TE) forecasts project completion in 89 calendar days, five days beyond the contracted 84 days. Employing the Earned Value Method enhances project performance evaluation and decision-making to avoid delays and cost overruns.

Abstract

The construction project of the McD Pontianak building encountered significant challenges due to a tight schedule of 110 calendar days and unforeseen delays arising from the existing building's foundation. These delays led to a setback in the construction progress, prompting the need for strategic measures to accelerate the project and mitigate the delays amounting to 11.48%, equivalent to 12.63 days. The potential financial consequences of this delay were estimated at IDR 228,366,605. In order to expedite the construction process, the chosen acceleration method was the crashing method, involving an increase in overtime ranging from 1 to 4 working hours, in accordance with relevant laws and regulations. This required a comprehensive analysis encompassing normal cost, normal duration, critical path, productivity, crashing cost, and crashing duration calculations. Upon thorough examination, it was determined that the optimal solution to overcome the delays was to implement an additional 2 hours of overtime. However, this decision came with associated costs, resulting in a necessary expenditure of IDR 93,651,965 to achieve a crashing time of 18.30 days. Despite the increased financial commitment, this strategic approach was deemed essential to meet the project's original schedule and avoid potential penalties. The findings and conclusions drawn from this analysis provide valuable insights into effective project management and decision-making in the face of unexpected challenges in the construction industry.

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.

Abstract

This study aims to identify critical tasks in the construction of a 4-floor building at Kadiri University using the Critical Path Method (CPM). The project is planned to be completed within 43 weeks, from October 2023 to August 2024, with a budget of IDR 20,551,534,000. Data collection involved direct site visits for primary data and secondary data from project documentation, including the Cost Budget Plan (RAB) and project schedule. Using Microsoft Project software, a project network was mapped, and CPM analysis was performed to identify the critical path. The analysis revealed that several tasks, such as site cleaning, demolition, temporary project fencing, heavy equipment work, geotechnical work, and various structural works from the 1st to the 5th floors, are on the critical path. These tasks have zero slack time, indicating that any delays will directly impact the overall project timeline. Identifying the critical path is crucial for project managers to prioritize resources and efforts on these tasks to ensure the project stays on schedule. This study underscores the significance of CPM in project management for timely completion and effective resource allocation, providing valuable insights for managing similar construction projects.

Abstract

The lecture building is an important building which is the center of academic activities where educational activities are carried out. Currently, the construction of a four-story lecture building at Kadiri University is experiencing significant project delays with a deviation of 5.64% from the plan. Crash analysis can be carried out to speed up the duration of the project so that it can be completed on time with additional working hours. This research aims to determine crash time, crash costs, and cost slope for the application of overtime on the 4-story building construction project at Kadiri University. A quantitative and case study approach was used with data collected through observation, interviews, and analysis of project documents. Critical Path Method (CPM) analysis is carried out using Microsoft Project software to identify work that is on the critical path. Crashing is done by calculating crash time, crash cost, and cost slope. The research results show that applying 1 hour of overtime can speed up the project by 12 working days, with an additional cost of IDR 24,488,758. Cost slope analysis shows additional overtime costs of IDR 12,244,379. This research shows that the application of measurable overtime and crashing analysis can effectively overcome project delays in the context of building educational facilities.
