Abstract

In response to the increasing occurrence of rain, the city government is actively striving to mitigate urban flooding by enhancing the drainage system. Collaboration with contracted construction firms is central to this endeavor, although it is not without its challenges, including community opposition driven by concerns over potential disruptions and limited financial resources among contractors. This study adopts the Critical Path Method (CPM) and Microsoft Project software, supplemented with the Time Cost Trade Off (TCTO) method to expedite project completion, emphasizing a comprehensive evaluation that encompasses both time and financial aspects. Notably, the analysis identifies the most feasible acceleration opportunity within the excavation of ordinary soil for construction, with original plans indicating a cost of Rp. 60,818,919 over a 40-day period. Three alternatives are considered: (1) overtime labor, incurring Rp. 65,520,000, with a 34-day duration; (2) increased workforce, incurring Rp. 68,000,000, with a 34-day duration; and (3) introducing a new addendum for the replacement of manual excavation with heavy machinery, incurring Rp. 37,440,000, with a 16-day duration. In conclusion, this study provides a comprehensive strategy for accelerating the urban drainage project, considering the critical path, time-cost trade-offs, and cost-benefit factors, highlighting the significance of selecting the most cost-effective alternative while addressing community concerns and resource limitations in flood risk mitigation efforts.

Abstract

The Belanti II Swamp Irrigation Area in Pulang Pisau Regency, Central Kalimantan, spans 3,275 Ha. Water management activities, necessitated for sustained irrigation, incur the Water Resources Management Service Fee (BJPSDA), calculated on cost recovery principles. This study aims to (1) Determine the BJPSDA value by considering the economic benefit factor, (2) Assess farmers' Ability To Pay (ATP) and Willingness To Pay (WTP) for BJPSDA, and (3) Evaluate the Belanti II swamp irrigation network and optimization efforts. The BJPSDA in Belanti II is Rp5,625,504,000, with agricultural benefits contributing Rp51,468,721,052.40 (51.86% of NME). The cost is Rp570,151.69/Ha or Rp101/m3. Farmer ATP and WTP for BJPSDA are Rp54/m3. The irrigation system lacks proper water flow regulation structures, but optimization efforts include channel normalization and water control structures. To enhance leaching ability, 500 m3/ha/day of fresh water is needed. Structures like weirs and flap gates regulate water supply during high and low tides, respectively. These initiatives aim to ensure consistent irrigation and sustainable water resource management in Belanti II.

Abstract

Contractors involved in construction projects face the crucial challenge of effectively managing time to ensure the timely completion of the project as stipulated in the contract, if not earlier. Efficient time management not only facilitates adherence to contractual obligations but also transforms incurred costs into profitable outcomes, thereby preventing financial penalties associated with project delays. Consequently, the strategic implementation of acceleration efforts emerges as a pivotal solution to address and mitigate the complexities inherent in construction project timelines. The acceleration process is intricately tied to the identification and prioritization of critical activities within the project schedule. By employing a comprehensive approach that integrates both cost and time analyses, the Crashing method with additional modifications emerges as a valuable tool in this endeavor. The Crashing method involves a strategic acceleration of critical activities, coupled with a meticulous calculation of the additional costs incurred due to the acceleration process. A compelling case study that exemplifies the efficacy of the Crashing method and its supplementary measure of alternative overtime work is evident in the Tanjung Uncang Pier construction project in Batam City. Through the meticulous application of the Crashing method and the incorporation of alternative overtime work, the project's completion timeline was successfully curtailed from the originally delayed schedule of 257 calendar days to a more expedited 244 calendar days.
