Abstract

Karangagung Fishing Port (PPI) in the coastal area of Tuban Regency, Palang District is known as the fisheries base in Tuban Regency, even most of the fish production from the Karangagung PPI fishing port has been marketed to all regions in East Java province. The sustainability of the development of an infrastructure project is very important to consider in the development of infrastructure in the maritime sector, especially the fisheries sector. This research will produce an investment analysis on the development of the Karangagung Fishing Port (PPI) infrastructure project which is expected to increase the productivity of the fisheries sector in the area. The investment analysis method used includes the calculation of Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit Cost Ratio (BCR) with the analysis results of NPV value of 6,648,460,488.00, IRR 6.21% and BCR 1.0178 with an investment period of 25 years. From the results of the investment analysis that has been carried out, the NPV value is positive. then the IRR value or the rate of return on an investment with a value greater than the discount factor plan and the benefit value or BCR is more than 1 and the payback period in year 25 is the same as the investment period of 25 years. So, the feasibility of investment is still said to be feasible to use for handling the work of the Karangagaung Tuban Fishing Port Development.

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.
