This study used an experimental method which is conducted at the Laboratory of Materials and Construction Faculty of Engineering, University of Lampung. The sample for compressive strength test is a cylinder with a diameter of 15 cm and 30 cm in height, while the sample for flexural tensile strength test is a block with a length of 40 cm, 10 cm in width and 10 cm in height. The testing for the compressive strength and flexural tensilestrength of normal concrete with high-quality fiber-reinforced concrete 0; 0.25; 0.50; 0.75 and 1 performed after 14 and 28 days. Maximum compressive strength and flexural strength occurs at a height of 0,75 fiber-reinforced concrete. The maximum compressive strength is 27.3649 MPa, increasedby 3.5714%. The maximum flexural strength is 5.4880 MPa, increasedby 18.9475%. The addition of wire rope fiber does not make a major contribution to the increase of compressive strength, but the flexural tensile strength. The wire rope fiber in this study has high tensile strength, i.e. 1733.46 MPa so it can provide a significant increase in the flexural strength. Keywords : compressive strength, flexural strength, fiber concrete, wire rope fiber  AbstrakBeton merupakan salah satu bagian penting dalam perkembangan infrastruktur bangunan.

Abstract

Feasibility Analysis is an appropriate analysis of parameters to determine a successful implemented project or not. Feasibility analysis is divided into two parts economic and financial analysis that both affect the feasibility of a project. The purpose of this study is to determine the costs incurred in a railway shortcut project, to analyze delay times before and after a railway shortcut, and to find out which railway shortcut project meets the economic and financial feasibility requirements. In this study, an analysis of the economic and financial feasibility and summarize the economic viability benefits of the Tegineneng - Tarahan shortcut project was conduct. A project is declared feasible or not by doing comparison with the feasibility method that is NPV> 0, BCR> 1, PP faster than the specified time, IRR> capital cost, and PI> 1. This study uses full occupancy rate with discount rate of 5% , 10%, and 15%, respectively.Based on the results obtained in terms of economic feasibility analysis that investment evaluation does not qualify due to the amount of benefit is too small so that economic analysis is not feasible. The aspect of financial feasibility analysis and analysis by summing the two financial and economic benefits is eligible so that the Tegineneng - Tarahan shortcut project is categorized as feasible. Keyword : Economic Feasibility, Financial Feasibility, Feasibility Method
