Abstract

Waste management is a pressing issue in Probolinggo Regency and City, necessitating swift action to mitigate environmental impacts. The construction of the Probolinggo Regional Waste Landfill (TPA) aims to address this challenge through cross-regional sanitation services. Proper financing is crucial for successful infrastructure development, and this study compares government budget (APBN/APBD) and non-government (regional loans) financing schemes. Utilizing a quantitative approach with primary and secondary data, the analysis indicates the viability of both financing options. Government-sourced investment shows an NPV of Rp 431,148,007,790, IRR 40.55%, BCR 1.07, and a 3-year payback period. Meanwhile, non-government or regional loans exhibit an NPV of Rp 110,115,495,905, IRR 9.03%, BCR 1.3, and a 9-year payback period. The decision-making process, weighing financial and non-financial criteria, favors regional loans/loans as the preferred financing scheme for the Probolinggo TPASR project. This research emphasizes the importance of a well-selected financing scheme to ensure the success and sustainability of the Probolinggo Regional Waste Landfill infrastructure.

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.
