Abstract

A feeder system is a transportation system that aims to serve parts of the city that are beyond the reach of the main modes of transportation. The feeder system is designed to be used in residential areas towards the main road corridor so as to create a better hierarchy of public transportation systems between the main mode, branch mode, feeder mode. With the holding of this feeder, one of them is a milestone to increase LRT (Light Rail Transit) occupancy. The purpose of this research is to find out how effective and efficient feeder public transportation is and to find out the characteristics of passengers using feeder services on corridor 5, the analysis method used in this study uses a mixed method between descriptive and quantitative. Based on the results of the analysis that has been done, it is known that the background of different passengers at each observation point and the results of the feeder performance with a vehicle density value of 0.322 vehicles / hour, waiting time of 6 minutes, vehicle frequency of 4 - 5 vehicles / km, speed of 17 km / hour, travel time of 0.8 hours, operational capacity of 11.4%, headway 12 minutes, load factor 96% and utility 230 km in one day of operation.

Abstract

In Indonesia, infrastructure development such as bridges and buildings is rapidly advancing, with concrete serving as the primary material due to its compressive strength. However, concrete is susceptible to cracking caused by stresses and temperature variations, which can compromise the strength and safety of structures. These cracks can appear both before and after construction completion and are influenced by environmental factors as well as the inherent properties of the concrete itself. To address these weaknesses, various studies have shown that adding fibers, particularly steel wire fibers with high tensile strength, can help inhibit crack propagation. Therefore, research was conducted on the use of steel wire fibers with a content of 0.5–1.5% to investigate their effects on the mechanical strength and crack patterns of concrete with a compressive strength of 25 MPa. The compressive strength tests indicated that all samples experienced strength increases over time, with the addition of 1% and 1.5% steel fibers providing the most significant and stable improvements, accelerating hardening and enhancing the load-bearing capacity of the concrete. Crack patterns varied based on age and fiber concentration, with parallel crack patterns being more dominant at higher fiber contents, while cone-shaped and shear cracks were more common in concrete without fibers or with lower fiber contents.
